More specifically, the engagement hole 315 is provided on a side wall of the cover recess 3102 opposite to the first side 331 of the cover 33, and the engagement end 3911 can at least partially protrude from the second side 332 of the cover 33 and engage with the engagement hole 315. Wherein, the opening/closing releasing lock 391 is movably disposed in the accommodation recess 33c. The upper cover 33a (i.e., the upper surface of the cover 33) is provided with an operation port 334 communicating with the accommodation recess 33c. When the opening and closing releasing member 391 is located at the first position, the releasing portion 3912 faces the operation opening 334, so that the releasing portion 3912 can be operated by the operation opening 334 to move the releasing member 391, and when the opening and closing releasing member 391 is located at the second position, the engaging end portion 3911 extends out of the accommodating recess 33c to engage with the engaging hole 315. The rotation direction of the releasing member 322 when releasing the lock is opposite to the rotation direction of the cover 33 when opening. Taking fig. 31 as an example, unlocking is achieved when the release 322 is rotated in a counterclockwise direction, and the cover 33 is opened when rotated in a clockwise direction. Thus, the cover 33 can be prevented from being opened by mistake when the lock release member 322 releases the lock.

Referring to fig. 32 in combination, the opening and closing mechanism 39 further includes an opening and closing reset member 392. The opening and closing reset piece 392 is disposed between the cover 33 and the opening and closing releasing lock piece 391, and the opening and closing reset piece 392 is abutted against the opening and closing releasing lock piece 391 to bias the opening and closing releasing lock piece 391 to move to the first position. The open-close reset member 392 is, for example, a compression spring. Referring to fig. 33 again, the upper cover 33a is provided with an abutment rib 335, and the abutment rib 335 is positioned in the accommodation recess 33 c. The opening and closing reset member 392 is accommodated in the accommodation recess 33c, one end of the opening and closing reset member 392 abuts against the opening and closing release lock member 391, and the other end of the opening and closing reset member abuts against the abutment rib 335. Specifically, the shutter release lock 391 is provided with a shutter recess 3913, the shutter recess 3913 being a groove open toward the upper cover 33a, the abutment rib 335 extending into the shutter recess 3913, the shutter release lock 392 being housed in the shutter recess 3913 and abutting against a side wall of the shutter recess 3913. More specifically, the reset piece recess 3913 is provided between the engagement end portion 3911 and the release portion 3912, and is located in front of the release portion 3912.

As shown in fig. 31 and 32, the child booster seat 3 is provided with two opening and closing mechanisms 39, but is not limited thereto. The two opening and closing mechanisms 39 are symmetrically disposed on the cover 33. The moving directions of the opening and closing lock 391 of the two opening and closing mechanisms 39 are substantially parallel to each other. Specifically, the moving direction of each opening and closing lock 391 is substantially perpendicular to the second side 331 of the cover 33. That is, when the cover 33 is in the closed state, each of the open/close lock 391 can be moved substantially in the front-rear direction.

Fig. 42 to 43 show perspective views of a child booster seat 3 provided in accordance with a further embodiment of the present application. In fig. 42, the cover 33 is in a closed state, and in fig. 43, the cover 33 is in an open state.

As shown in fig. 42 to 43, the cover 33 is provided to be openable and closable at the opening of the storage recess 314 by the opening and closing mechanism 39. The cover 33 is substantially rectangular in cross section, but is not limited thereto. The cover 33 has oppositely disposed left and right sides. The opening and closing mechanism 39 in the present embodiment is different from the opening and closing mechanism 39 in the embodiment shown in fig. 31 to 33 described above at least in the following.

As shown in fig. 45, the opening and closing mechanism 39 includes two opening and closing releasing lock pieces 391 and an opening and closing resetting piece 392 provided between the two opening and closing releasing lock pieces 391. The two opening and closing locks 391 are symmetrically disposed on the left and right sides of the cover 33. Two opening and closing releasing locks 391 are movably provided on the cover 33. When the two opening and closing locks 391 move between the first position and the second position, the two opening and closing locks 391 move in opposite directions, respectively. In some alternative embodiments, the left and right sides of the cover 33 are respectively provided with an opening and closing mechanism 39, and each opening and closing mechanism 39 includes an opening and closing releasing lock 391 and an opening and closing resetting member 392 disposed between the opening and closing releasing lock 391 and the cover 33.

For convenience of description, referring to fig. 43 and 45, an opening/closing lock 391 provided on the left side of the cover 33 is exemplified in the present embodiment.

As shown in fig. 43 and 45, the moving direction of the opening/closing lock 391 is substantially perpendicular to the left side of the cover 33. That is, the moving direction of the opening/closing lock 391 is substantially parallel to the first side 331 of the cover 33. That is, the movement direction of the opening/closing lock 391 is substantially parallel to the left-right direction. Accordingly, the engagement hole 315 is provided on the side wall of the storage recess 314 or on the side wall of the cover recess 3102. The engaging end 3911 of the opening/closing releasing lock 391 can at least partially protrude to the left of the cover 33, so that the engaging end 3911 can engage with the engaging hole 315. Specifically, when the opening/closing releasing lock 391 is in the first position, the engaging end portion 3911 extends out of the left side of the cover 33 and is capable of engaging with the engaging hole 315, and when the opening/closing releasing lock 391 is in the second position, the engaging end portion 3911 is retracted into the cover 33 such that the engaging end portion 3911 is separated from the engaging hole 315.

As shown in fig. 44, the opening/closing lock 391 includes a lock release knob 391a and an engagement pin 391b penetrating the lock release knob 391 a. The engagement pin 391b is fixedly or detachably connected to the release knob 391 a. A portion of the engagement pin 391b that passes out of the lock release knob 391a is formed as an engagement end 3911. The opening and closing lock 391 is provided with an operation recess 3914, and the operation recess 3914 is a groove provided on the lock release knob 391a with an opening facing upward. A side wall of the operation recess 3914 remote from the engagement end portion 3911 is formed as at least a part of the lock release portion 3912. When the opening/closing lock 391 is located at the first position, at least a portion of the operation recess 3914 is aligned with the operation opening 334 of the cover 33, and at least a portion of the operation recess 3914 is exposed from the operation opening 334, so as to allow the operation opening 334 to extend into the recess 3912a and push the operation recess 3914, thereby pushing the opening/closing lock 391 to move to the second position. When the opening/closing lock 391 is located at the second position, at least a portion of the operation recess 3914 is exposed to the operation opening 334. The opening/closing release lock 391 is further provided with a stopper 3915. The limiting portion 3915 protrudes from an opening of the operation recess 3914 and can at least partially extend into the operation opening 334. In this way, the movement stroke of the opening/closing lock release 391 can be limited by the stopper action of the side wall of the operation opening 334 on the stopper portion 3915, so that the lock release portion 3912 is prevented from being moved to be offset from the operation opening 334, and the opening/closing lock release 391 can be operated by the stopper portion 3915 and the lock release portion 3912 together.

As shown in fig. 45, the shutter 392 is, for example, a compression spring. The opening and closing reset piece 392 is respectively abutted with the two opening and closing releasing locking pieces 391, so that the two opening and closing releasing locking pieces 391 respectively move to the first positions. That is, when any one of the shutter lock 391 is not operated, the shutter lock 391 that is not operated is maintained at the first position by the shutter reset member 392. Specifically, each of the opening and closing releasing latches 391 is provided with a restoring member concave portion 3913, and the restoring member concave portion 3913 is provided to the releasing knob 391a and is located on a side of the operating concave portion 3914 away from the engaging end portion 3911. A boss 3916 is arranged in the reset piece concave portion 3913, two ends of the opening and closing reset piece 392 are respectively accommodated in the reset piece concave portion 3913 of the two opening and closing release lock pieces 391, and two ends of the opening and closing reset piece 392 are respectively sleeved on the corresponding boss 3916. This prevents the return element 392 from being deflected during elastic energy storage. In the present embodiment, when the two opening and closing releasing locks 391 are moved from the first position to the second position, the two opening and closing releasing locks 391 are moved in directions approaching each other, respectively. Specifically, the opening and closing locks 391 distributed on the left side of the cover 33 are moved rightward, and the opening and closing locks 391 distributed on the right side of the cover 33 are moved leftward. In other words, when the opening and closing mechanism 39 needs to be released, the opening and closing releasing pieces 391 are pushed against or simultaneously pressed in a direction to bring the two opening and closing releasing pieces 391 closer to each other, so that the two opening and closing releasing pieces 391 are simultaneously moved from the first position to the second position.

As shown in fig. 10, 12 and 34, the child booster seat 3 further includes a cup holder 38, the cup holder 38 being removably connected to the at least one armrest portion 34, the cup holder 38 having a generally circular cross-section for facilitating placement of objects such as water cups, while reducing interference of the cup holder 38 with nearby objects or adjacent passengers. At least one of the armrest portions 34 is provided with a cup holder recess 343 adapted to snap into place with the storage cup holder 38. In the present embodiment, the outer side surfaces 342 of the two armrest portions 34 are each provided with a cup holder recess 343, and the number of the storage cup holders 38 is one, so that the user can select to engage the storage cup holder 38 with one of the cup holder recesses 343 as required. In another embodiment, referring to fig. 1, the number of the storage cup holders 38 is two, and the two storage cup holders 38 are respectively and correspondingly clamped at the two cup holder recesses 343. It should be understood that in other embodiments, the number of cup holders 38 may be greater than two, and the number of cup holder recesses 343 may be greater than two, without limiting the application.

For ease of description, one of the handle portions 34 and the cup holder 38 disposed thereon will be described below.

As shown in fig. 34, the armrest portion 34 includes a first armrest portion 34a located on the front side of the first sleeve hole 36 and a second armrest portion 34b located on the rear side of the first sleeve hole 36, and a cup holder recess 343 is provided in the first armrest portion 34a. The storage cup holder 38 is provided with a connection protrusion 381, the cup holder recess 343 is provided with an entry slot 344 through which the limiting hole 345 communicates, and the connection protrusion 381 enters the limiting hole 345 through the entry slot 344 to lock to fix the storage cup holder 38 at the cup holder recess 343. The cup holder 38 includes a cup 383, and a connecting protrusion 381 is disposed on a sidewall of the cup 383. Specifically, the connection protrusion 381 includes a connection portion 3811 and a locking portion 3812, and the connection portion 3811 is connected between the locking portion 3812 and a sidewall of the storage cup 383. The locking portion 3812 is connected to the connection portion 3811 and extends in a direction parallel to a sidewall of the connection portion 3811 with a space from the connection portion 3811. The cup holder recess 343 has a side wall 3431 and a bottom wall 3432, and the access slot 344 and the retaining hole 345 are provided through the side wall 3431. The locking portion 3812 of the connection protrusion 381 passes through the entry groove 3411 so that the locking portion 3812 may penetrate from the inner sidewall 3431a of the cup holder recess 343 to the outer sidewall (not shown in the drawings) of the cup holder recess 343, and the connection portion 3811 of the connection protrusion 381 enters into the spacing hole 345 along the entry groove 3411 so that the locking portion 3812 abuts against the outer sidewall of the cup holder recess 343 at the spacing hole 345, thereby locking the connection protrusion 381 at the spacing hole 345.

With continued reference to fig. 34, the access slot 344 is generally L-shaped. The access slot 344 includes a first slot segment 3441 and a second slot segment 3442 in communication with each other, the second slot segment 3442 being located between the first slot segment 3441 and the spacing aperture 345. The first groove section 3441 extends in a direction substantially perpendicular to the bottom wall 3432, and the second groove section 3442 extends in a direction substantially parallel to the bottom wall 3432 (i.e., in a circumferential direction substantially parallel to the cup holder recess 343). The distance between the opposing sidewalls of the first slot section 3441 is greater than the distance between the opposing sidewalls of the second slot section 3442. Wherein the connection protrusion 381 is free to pass through the first slot section 3441 (i.e., the locking portion 3812 of the connection protrusion 381 is free to pass into or out of the first slot section 3441), while the locking portion 3812 of the connection protrusion 381 is not free to pass into or out of the second slot section 3442, the connection protrusion 381 slides in its extension direction relative to the second slot section 3442.

As shown in fig. 34, a limiting protrusion 349 is disposed at a transition between the second slot section 3442 of the inlet slot 344 and the limiting hole 345, and the limiting protrusion 349 protrudes from a side wall of the second slot section 3442 and is used for limiting the connecting portion 3811 of the connecting protrusion 381 in the limiting hole 345, so as to avoid accidental separation of the connecting protrusion 381 from the limiting hole 345. The connecting portion 3811 of the connecting protrusion 381 can push against the limiting protrusion 349 to deform, so that the connecting protrusion 381 can slide to the limiting hole 345 or slide from the limiting hole 345. Specifically, the number of the limiting protrusions 349 is two, and the two limiting protrusions 349 are axisymmetrically distributed into the transition between the second slot section 3442 of the slot 344 and the limiting hole 345. The cup holder concave portion 343 is provided with deformation holes 347, the number of which coincides with the number of the limit convex portions 349. In the present embodiment, the number of the deformation holes 347 is two, and the two deformation holes 347 are axisymmetrically distributed on both sides of the limit hole 345 and are respectively located on both sides of the two limit protrusions 349. Specifically, two deformation holes 347 are provided near the upper and lower sides of the limit hole 345, and are axisymmetrically distributed with respect to the limit hole 345. The deformation hole 347 is configured to deform the limiting protrusion 349 and its vicinity during pushing of the limiting protrusion 349 by the connection portion 3811 of the connection protrusion 381, so that the connection protrusion 381 passes over the limiting protrusion 349, and the connection protrusion 381 can be conveniently locked into or withdrawn from the limiting hole 345.

In order to more firmly connect the storage cup holder 38 at the cup holder recess 343, the storage cup holder 38 is further provided with a connecting post 382, which connecting post 382 is provided at the bottom wall of the storage cup 383. The cup holder recess 343 is provided with a first connecting hole 346, and the connecting post 382 is fitted to the first connecting hole 346.

In the above embodiment, the process of mounting the cup holder 38 at the holder recess 343 is performed by first aligning the connection post 382 with the first connection hole 346 and passing the connection protrusion 381 through the first slot section 3441 of the access slot 344, then moving the cup holder 38 down along the first slot section 3441 to slide the connection protrusion 381 to the transition between the first slot section 3441 and the second slot section 3442, in which process the connection post 382 is inserted into the first connection hole 346, then rotating the cup holder 38 clockwise to slide the connection protrusion 381 down the second slot section 3442 of the access slot 344 toward the spacing hole 345, and continuing rotating the cup holder 38 clockwise, the connection part 3811 of the connection protrusion 381 pushing the spacing protrusion 349 and over the spacing protrusion 349 to slide the connection protrusion 381 to the spacing hole 345, thereby locking the connection protrusion 381 with the spacing hole 345.

The process of removing the storage cup holder 38 from the cup holder recess 343 is opposite to the above-described process of mounting at the cup holder recess 343, specifically, by first rotating the storage cup holder 38 counterclockwise, the connecting portion 3811 of the connecting protrusion 381 pushing against the spacing protrusion 349 and over the spacing protrusion 349 so that the connecting protrusion 381 slides from the spacing hole 345 to the second groove section 3442 of the entry groove 344, continuing to rotate the storage cup holder 388 clockwise so that the connecting protrusion 381 slides along the second groove section 3442 of the entry groove 344 to the first groove section 3441, and when the connecting protrusion 381 slides to the transition between the first groove section 3441 and the second groove section 3442, moving the storage cup holder 38 upward so that the connecting protrusion 381 slides along the first groove section 3441, during which the connecting post 382 withdraws from the first connecting hole 346, and finally withdrawing the connecting protrusion 381 from the first groove section 3441 of the entry groove 344.

The second end of the second webbing 72 remote from the first webbing 71 is connected to the bottom wall of the storage recess 314, or passes through the bottom wall of the storage recess 314 and is connected to other structures provided on the seat cushion body 31. When the connecting strap assembly 7 is not in use, it may be stored in the storage recess 314, i.e. both the second webbing 7 and the connector 73 may be accommodated in the storage recess 314. When the connecting assembly 7 is used, the two connectors 73 respectively arranged on the first webbing 71 respectively pass through the second sleeve holes 348 on the corresponding armrest parts 34 and are locked with the automobile seat connectors arranged on the automobile seat, and meanwhile, the second webbing 72 and a part of the first webbing 71 are clamped in the storage concave part 314 through the closing of the cover body 33, so that the first webbing 72 is prevented from rising above the upper surface of the seat cushion 3 of the child when being tensioned, and is pulled to the buttocks of the child.

As shown in fig. 10 to 11, in one embodiment, the seat cushion body 31 includes a front end 31c and a rear end 31d. In one embodiment, the front end 31c refers to the front half of the seat cushion body 31 in the front-rear direction (i.e., the first direction D1), the rear end 31D refers to the rear half of the seat cushion body 31 in the front-rear direction, and the intermediate line of the seat cushion body 31 in the left-right direction (i.e., the second direction D2) constitutes the boundary between the front end 31c and the rear end 31D. Illustratively, referring to FIG. 2, the portion of the seat cushion body 31 to the left of the U1-U1 cut line is a front end 31c and the portion to the right of the A-A cut line is a rear end 31d. With continued reference to fig. 10 and 11, the seat cushion body 31 is provided with an engagement groove 311, the engagement groove 311 being located at the lower surface 31b of the seat cushion body 31. The mating slot 311 is adapted to snap-fit with at least a portion of the back assembly 2. Specifically, the fitting groove 311 is substantially U-shaped. The fitting groove 311 includes two first groove portions 3111 and a second groove portion 3112 communicating with the two first groove portions 3111. The two first groove portions 3111 are substantially parallel to each other, and each first groove portion 3111 extends from the rear end 31D toward the front end 31c, that is, extends forward in the first direction D1. The two first groove portions 3111 are adapted to be respectively engaged with the two fitting ribs 22 to restrict the movement of the child booster seat 3 relative to the fitting ribs 22 in the direction perpendicular to the first direction D1. Both ends of the second groove 3112 communicate with the first groove 3111, respectively. Referring to fig. 9 in combination, the second slot 3112 is adapted to at least partially receive the crossbar 23, and a side wall of the second slot 3112 on the side of the backrest body 21 is capable of abutting the crossbar 32 to limit movement of the child booster seat 3 relative to the crossbar 23 in the first direction D1, i.e., to limit forward movement of the child booster seat 3 relative to the crossbar 23. Of course, in other embodiments not shown, the engaging groove 311 may be provided with only the first groove portion 3111, and the first groove portion 3111 is engaged with the engaging rib 22, which is not limited to the present application.

In one embodiment, as shown in fig. 8, 9 and 12, the child booster seat 3 is provided with a connection mechanism 32, the connection mechanism 32 being connected to the seat main body 31, and the child booster seat 3 being connected to the back assembly 2 through the connection mechanism 32. The connecting mechanism 32 is disposed near the front end 31c of the seat cushion body 31. The connection mechanism 32 includes a locking member 321, a releasing member 322, and an elastic member 323. The lock 321 is pivotally connected to the seat main body 31 and has a hook portion 3211. The lock 321 is pivotable between a lock release position and a lock position. When the locking piece 321 is located at the locking position, the locking piece 321 is clamped with the backrest assembly 2 to allow the child booster seat cushion 3 to be connected with the backrest assembly 2, and when the locking piece 321 is located at the unlocking position, the locking piece 321 is unclamped with the backrest assembly 2 to allow the child booster seat cushion 3 to be separated from the backrest assembly 2. Specifically, referring to fig. 8, when the locking member 321 is in the locking position, the hook portion 3211 of the locking member 321 is inserted into the second groove portion 3112 to engage with the rail 23, and referring to fig. 9, when the locking member 321 is in the unlocking position, the hook portion 3211 is adapted to disengage from the rail 23 (i.e., the hook portion 3211 is disengaged from the rail 23 and leaves the second groove portion 3112).

In other not shown embodiments, the locking member 321 may also slide in the first direction D1, the second direction D2, or the third direction D3 relative to the seat cushion body 31. In these embodiments, the end of the locking member 321 is connected to the end of the release member 322 by a driving structure such as a steel wire, a bevel, or the like. When the locking member 321 slides relative to the seat cushion body 31, the locking member 321 drives the driving structure to move, and the driving structure pulls or pushes the end of the locking member 322, so that the locking member 322 rotates in the direction of the lock releasing position.

Referring to fig. 8 and 9, in one embodiment, the locking member 321 is generally C-shaped. The lock 321 is provided with a pivot portion 3214 and a driving portion 3213 connected to the pivot portion 3214. The seat cushion body 31 is provided with a passage 313, and the passage 313 penetrates the first seat cushion shell 301 and the second seat cushion shell 302. The locking member 321 is disposed through the channel 313, and the pivot portion 3214 and the driving portion 3213 can extend out from one end of the channel 313. The pivot portion 3214 is pivotally connected to the seat cushion main body 31 and to the release lock 322, and the release lock 322 is pivotally connected to the seat cushion main body 31. The locking piece 321 can be driven to pivot by the driving portion 3213 when the release locking piece 322 pivots. The catch portion 3211 can at least partially penetrate out of the channel 313, and in particular, the catch portion 3211 can penetrate out of the other end of the channel 313 and be inserted into the second slot portion 3112 to be engaged with the rail 23. The cross bar 23 has an upper side 231, a lower side 232, a rear side 233 facing the back main body 21, and a front side 234 facing away from the back main body 21. The locking piece 321 is engaged with the rear side 233 of the cross bar 23 in the direction of the front side 234 (i.e., engaged with the cross bar 23 in the counterclockwise direction). The side walls of the channel 313 form a first stopper 3132 and a second stopper 3131, thereby restricting the pivoting range of the locking member 321. In the present embodiment, a side wall of one side of the second groove portion 3112 of the fitting groove 311 (a side wall of the second groove portion 3112 on the side close to the backrest main body 21) is formed as the first stopper portion 3132. When the locking member 321 is at the locking position, the locking member 321 is abutted by the first limiting portion 3132, and the hook portion 3211 can penetrate out of the channel 313 and be inserted into the second groove portion 3112 to be engaged with the lower side 232 of the cross bar 23. In this way, the child booster seat 3 cannot move forward in either the front-rear direction (i.e., the first direction) or upward in the up-down direction (i.e., the third direction D3) relative to the crossbar 23 (the back assembly 2). When the locking member 321 is located at the lock release position, the locking member 321 abuts against the second stopper 3131. The pivoting range of the locking member 321 can be limited between the locking position and the unlocking position by providing the first and second stopper portions 3132 and 3131, thereby avoiding excessive pivoting of the locking member 321.

As shown in fig. 8 and 9, the hook portion 3211 of the lock 321 is provided with a wedge surface 3212, and the wedge surface 3212 is provided at one end of the hook portion 3211. The wedge surface 3212 is adapted to be pushed against the rail 23 to pivot the locking member 321, thereby allowing the catch portion 3211 to be snapped into engagement with the rail 23. The upper side 231 of the cross bar 23 is curved or beveled to facilitate a smoother abutment against the wedge 3212. The lower side 232 of the cross bar 23 is substantially planar, and the lower side 232 is slightly inclined from the front side 234 toward the rear side 233, so that the lower side 232 can be more firmly engaged with the hook portion 3211.

In one embodiment, as shown in fig. 8, 9 and 12, the release 322 has a pivot recess 3221. Specifically, the release member 322 includes a top portion 3222 and two opposite side portions 3223, the two side portions 3223 are respectively connected to two sides of the top portion 3222 and are substantially parallel to each other, and the top portion 3222 and the two side portions 3223 enclose a pivot recess 3221. The release 322 is generally U-shaped. A pivot recess 3221 is formed at both ends of the release piece 322, and a handle portion 3224 is provided between both ends of the release piece 322. The upper surface 31a of the seat cushion body 31 is provided with a receiving groove 312, and the receiving groove 312 is formed by the first seat cushion housing 301. The release lock 322 is received in the receiving slot 312 and pivotally coupled to a side wall of the receiving slot 312. Specifically, both ends of the release latch 322 are pivotally connected to the side walls of the receiving groove 312, respectively. More specifically, both side portions 3223 are pivotally connected to the side walls of the receiving groove 312 by the pin shafts 324.

With continued reference to fig. 8, 9 and 12, the receiving groove 312 communicates with the channel 313 such that the pivot portion 3214 of the locking member 321 can extend into the receiving groove 312 to pivotally connect with a side wall of the receiving groove 312. The pivot portion 3214 is at least partially received in the pivot recess 3221, and the driving portion 3213 can at least partially extend out of the pivot recess 3221, so that the driving portion 3213 can be pushed by the release lock 322. The pivot axis of the locking member 321 relative to the seat cushion body 31 and the pivot axis of the release locking member 322 relative to the seat cushion body 31 are collinear or parallel. In the present embodiment, the lock release member 322 and the lock release member 321 are pivotally connected to the seat cushion body 31 by the same pin 324, and the lock release member 321 and the lock release member 322 can pivot with respect to the pin 324. Specifically, the pin shaft 324 is respectively inserted into the locking member 321 and the releasing member 322, and two ends of the pin shaft 324 are respectively fixedly connected with two side walls of the accommodating groove 312. More specifically, the pin 324 is coupled to the sidewall of the receiving groove 312 through both sides 3223 of the release lock 322 and the lock 321. In another embodiment, the releasing locking member 322 and the locking member 321 may be pivotally connected to the seat cushion body 31 by a plurality of pins 324, for example, each pivot recess 3221 is pivotally connected to two sidewalls of the receiving groove 312 by two pins 324, respectively, and is connected to the locking member 321, which is not limited to the present application.

As shown in fig. 8 and 9, the release lock 322 is pivotable between a first position and a second position to actuate the lock 321 to pivot between the locked and release positions. The angle between the release lock 322 and the seat cushion body 31 when the release lock 322 is in the second position is larger than the angle between the release lock 322 and the seat cushion body 31 when the release lock 322 is in the first position. In this embodiment, when the releasing member 322 is in the first position, the locking member 321 is located at the locking position, and the releasing member 322 can be completely accommodated in the accommodating groove 312 (i.e. the releasing member 322 does not protrude out of the accommodating groove 312). More specifically, when the lock release 322 is in the first position, the lock release 322 is just flush with the upper surface 31a of the seat cushion body 31. In this way, a relatively flat seating surface may be provided, improving the comfort of a child riding on the child booster seat 3. When the release member 322 is pivoted to the second position, the locking member 321 is in the release position, and the handle portion 3224 of the release member 322 is disengaged from the receiving groove 312. In this way, the release 322 can be conveniently operated.

Optionally, the release 322 is provided with a third position, which is located between the first position and the second position. When the release lock 322 pivots from the first position to the third position, the pivot recess 3221 of the release lock 322 cannot pivot against the driving portion 3213 of the push lock 321, that is, the first position to the third position are the buffer strokes of the release lock 322. The locking member 321 is maintained in the locking position during the buffer stroke of the release member 322. By providing the buffer stroke, the locking piece 321 and the cross bar 23 can be prevented from being released from the locking piece 322 due to misoperation, and the safety of the connection of the child height-increasing seat cushion 3 and the backrest assembly 2 is improved. When the release lock 322 is located at the third position, the end of the pivot recess 3221 of the release lock 322 just abuts against the driving portion 3213 of the lock 321, the lock 321 is located at the locking position, and the end of the pivot recess 3221 can abut against the driving portion 3213 to drive the lock 321 to pivot. When the release lock 322 pivots from the third position to the second position, the end of the pivot recess 3221 can push against the driving portion 3213 to drive the lock 321 to pivot from the locking position to the release position. In the present embodiment, when the lock release 322 is located at the first position, the lock release 322 is substantially parallel to the upper surface 31a of the seat cushion body 31, i.e., the angle between the lock release 322 and the upper surface 31a is about 0 °. When the release member 322 is in the second position, the angle between the release member 322 and the upper surface 31a is approximately 90 °. When the release member 322 is in the third position, the angle between the release member 322 and the upper surface 31a is approximately 60 °. The buffer travel range of release 322 is approximately (0, 60). Of course, the angles between the locking member 322 and the upper surface 31a in the first, third and second positions may be set to other angles, which is not a limitation of the present application.

As shown in fig. 8, 9 and 12, in the present embodiment, the number of the locking pieces 321 is one. The locking member 321 is connected with a pivot recess 3221 at one of the ends of the release member 322. In other embodiments, the number of locking pieces 321 may be two, and the two locking pieces 321 are connected to the pivot recesses 3221 at the two ends of the releasing piece 322 through the pins 324, respectively. Of course, in other embodiments, more than two locking members 321 may be configured according to the shape of the releasing member 322 and the actual requirement, and the locking members 321 are pivotally connected to the releasing member 322 respectively, which is not limited by the present application. The release lock 322 pushes the driving portion 3213 by the end of the top 3222, driving the lock 321 to pivot in the same direction (e.g., the rotational direction R1, i.e., the clockwise direction) as the release lock 322.

In another embodiment, as shown in fig. 31 and 32, the connection mechanism 32 includes a release member 322, a locking member 321, and an elastic member 323. The structure of the locking member 321 may refer to the structure of the locking member 321 in the above embodiment, and the structure of the elastic member 323 may refer to the structure of the third elastic member 323c in the following embodiment, which will not be described herein. The lock release 322 in this embodiment is different from the lock release 322 in the embodiment shown in fig. 8 and 9 described above mainly in the following.

In another embodiment, as shown in fig. 31 and 32, the release member 322 is in driving connection with the locking member 321 detachably, i.e. it corresponds to the driving connection of the release member 322 with the locking member 321 and the two members can be separated from each other. The release locking element 322 is pivotally connected to the second cover portion 33e of the cover 33, specifically, the upper surface 31a of the cover 33 is provided with a concave accommodating groove 312, and the accommodating groove 312 is used for accommodating the release locking element 322. The two ends of the releasing member 322 are pivotally connected to the side walls of the receiving recess 312, respectively. The lock 321 is pivotally connected to a rotation recess 3101 of the seat cushion main body 31, wherein the rotation recess 3101 penetrates a bottom wall of the cover recess 3102. Referring to fig. 28 in combination, the lower case 33b of the cover 33 is provided with a through hole 3105, and the through hole 3105 communicates with the accommodation groove 312. The perforation 3105 is used for passing at least one of the releasing locking piece 322 and the locking piece 321, so that the releasing locking piece 322 can drive the locking piece 321 to rotate. The driving portion 3213 of the locking member 321 at least partially penetrates the rotation recess 3101 and protrudes into the cover recess 3102. When the cover 33 is in the closed state, the receiving groove 312 communicates with the cover concave portion 3102 through the perforation 3105, so that when the release lock 322 rotates, the driving portion 3213 can be pushed against, thereby driving the lock 321 to pivot.

Fig. 13 to 14 show perspective views of the elastic member 323 according to an embodiment of the present application. Fig. 15 shows a perspective view of an elastic member 323 according to another embodiment of the present application.

As shown in fig. 12 to 14, in an embodiment, the elastic member 323 includes a first elastic member 323a, and the first elastic member 323a is, for example, a torsion spring. The elastic member 323a is sleeved on the pin shaft 324, and the elastic member 323a includes a first end portion 3233 connected to the seat cushion main body 31, a second end portion 3234 connected to the release lock member 322, and a third end portion 3235 connected to the lock member 321. Specifically, the first end portion 3233 is accommodated in the accommodation chamber 303 and abuts against the second cushion housing 302 of the cushion main body 31. The second end portion 3234 is engaged with the releasing member 322, and the third end portion 3235 is engaged with the locking member 321. The second end 3234 biases the release 322 toward the first position to pivot the release 322 toward the first position. The third end portion 3235 biases the locking member 321 toward the locking position to pivot the locking member 321 toward the locking position. In the present embodiment, the first elastic member 323a is an integral member to facilitate the installation of the first elastic member 323a.

As shown in fig. 15 and 16, in another embodiment, the elastic member 323 includes a second elastic member 323b and a third elastic member 323c. The second elastic member 323b and the third elastic member 323c are, for example, torsion springs, respectively. Referring to fig. 12, the second elastic member 323b and the third elastic member 323c are sleeved on the pin 324. One end of the second elastic member 323b abuts against the seat cushion main body 31, and the other end of the second elastic member 323b is engaged with the release lock member 322. The second elastic member 323b biases the release member 322 toward the first position to pivot the release member 322 toward the first position. One end of the third elastic member 323c abuts against the seat cushion main body 31, and the other end thereof engages with the locking member 321. The third elastic member 323c biases the locking member 321 toward the locking position to pivot the locking member 321 toward the locking position. The elastic member 323 in this embodiment includes two independent torsion springs, which is simple in structure and low in cost.

In other not shown embodiments, the elastic member 323 may include only the third elastic member 323c that biases the locking member 321 toward the locking position. In the present embodiment, the lock release member 322 is driven to pivot from the second position to the third position by the lock release member 321 pivoting from the lock release position to the lock position, and when the lock release member 322 is located at the third position, the lock release member 322 pivots from the third position to the first position under the action of its own weight.

In still another embodiment, the elastic member 323 may include only the second elastic member 323b biasing the locking member 321 toward the first position. The release member 322 is provided with a bottom portion (not shown) opposite the top portion 3222, the bottom portion being connected between the successive side portions 3223. At least a portion of the driving portion 3213 of the locking member 321 can extend out of the pivot recess 3221 from between the top portion 3222 and the bottom portion. When the release member 322 pivots from the second position to the first position, the bottom portion can push the driving portion 3213 to pivot the locking member 321 from the release position to the locking position.

In one embodiment, as shown in fig. 5 and 7, the rear end 31d of the seat cushion body 31 is provided with a catching groove 319, and the catching groove 319 communicates with the first groove portion 3111 of the fitting groove 311. The groove wall (e.g., bottom wall) of the locking groove 319 forms a first locking slope 3191. The first engagement slope 3191 is provided obliquely to the upper surface 31a of the seat cushion main body 31. The mating rib 22 is provided with an abutment 223. The abutment portion 223 is provided with a second engagement slope 222 adapted to cooperate with the first engagement slope 3191. In the present embodiment, the abutting portion 223 is provided inside the mating rib 22. When the child booster seat 3 is connected to the back assembly 2, the abutment 223 is at least partially received in the clamping groove 319, and the first engagement slope 3191 abuts against the second engagement slope 222 to prevent movement of the child booster seat 3 relative to the back 2 in the first direction D1 (i.e., front-rear direction) and in the third direction D3 (i.e., vertical direction, also referred to as up-down direction), thereby engaging the child booster seat 3 between the back main body 21 and the base 9. Wherein the third direction D3 is substantially perpendicular to the first direction D1. As shown in fig. 24, in another embodiment, the fitting rib 22 is provided with abutment portions 223 on both the inner side and the outer side. In another alternative embodiment, the abutment 223 may be provided on the back main body 21. It will be appreciated that in other embodiments not shown, the rear end 31d of the seat cushion main body 31 may be provided with an abutment portion 223, the abutment portion 223 may be provided with a first engagement inclined surface 3191, the backrest main body 21 may be provided with a locking groove 319, and the locking groove 319 may be provided with a second engagement inclined surface 222 adapted to cooperate with the first engagement inclined surface 3191.

In the present embodiment, the front end 31c of the seat cushion main body 31 is engaged with the cross bar 23 of the back assembly 2 through the connection mechanism 32, and the rear end 31D of the seat cushion main body 31 restricts the movement of the child booster seat cushion 3 in the first direction D1 and the third direction D3 by the engagement of the first engagement slope 3191 and the second engagement slope 222. And the movement of the child booster seat 3 in the direction perpendicular to the first direction D1 (i.e., the second direction D2, also referred to as the left-right direction or the lateral direction) is restricted by the snap fit of the fitting rib 22 with the fitting groove 311. In this way, the child booster seat 3 can be firmly attached to the back assembly 2.

In this embodiment, when the child booster seat 3 is to be removed from the back assembly 2, the release 322 is rotated in a clockwise direction R1 with reference to fig. 8. When the release lock 322 is rotated from the first position to the third position, the end of the U-shaped release lock 322 abuts against the driving portion 3213 of the lock 321. When the release lock 322 is rotated further from the third position to the second position, the end portion of the release lock 322 pushes the driving portion 3213 to rotate clockwise so that the lock 321 moves from the locking position to the release lock position. Referring to fig. 9, when the lock release member 322 is rotated to the second position, the lock member 321 is pushed to the lock release position, the hook portion of the lock member 321 is retracted into the channel 313 from the second groove portion 3112, and the lock member 321 is disengaged from the cross bar 23. The lock release 322 is held at the second position and is moved forward by applying an external force forward in the first direction D1 to the child up seat 3, so that the first engagement slope 3191 of the child up seat 3 is separated from the second engagement slope 222 (refer to fig. 7). Thereby, the child booster seat cushion 3 can be separated from the backrest assembly 2, at this time, the external force applied to the lock release member 322 can be released, the lock release member 322 rotates from the second position to the first position under the elastic restoring force of the elastic member 323, and the lock member 321 pivots from the lock release position to the lock position under the elastic restoring force of the elastic member 323.

When it is necessary to mount the child booster seat 3 to the back assembly 2, the seat main body 31 is pushed against the first direction D1, so that the first engagement slope 3191 engages with the second engagement slope 222. The front end 31c of the seat cushion body 31 is pressed in the opposite direction to the third direction D3, and the upper side 231 of the cross bar 23 pushes the wedge-shaped surface 3212 of the lock 321, causing the lock 321 to pivot in the clockwise direction. When the cross bar 23 moves in the third direction D3 relative to the base 3 to be separated from the wedge-shaped surface 3212, the locking member 321 pivots in the counterclockwise direction to be engaged with the cross bar 23 under the elastic restoring force of the elastic member 323, thereby realizing the installation of the child booster seat cushion 3 onto the backrest assembly 2.

In other embodiments not shown, the first engagement slope 3191 and the second engagement slope 222 may not be provided. For example, the connection mechanism 32 is provided at each of the positions near the rear end 31d and near the front end 31c of the cushion main body 31, and the cross bar 23 is provided at each of the end of the fitting rib 22 near the backrest main body 21 and the end far from the backrest main body 21. The two connection mechanisms 32 are disposed opposite to each other, that is, the two connection mechanisms 32 are engaged with the corresponding cross bars 23 in opposite directions (for example, in the first direction D1 and the opposite direction of the first direction D1). The present embodiment restricts the movement of the child booster seat 3 in the direction parallel to the first direction D1 (i.e., in the front-rear direction) and the third direction D3 (i.e., in the up-down direction) by the two connecting mechanisms 32 respectively engaging with the two cross bars 23, thereby firmly connecting the child booster seat 3 to the back assembly 2.

As shown in fig. 10 to 12, the child booster seat 3 is further provided with a crotch strap hole 37, the crotch strap hole 37 being for passing a crotch strap 41 (refer to fig. 1) of the child safety seat therethrough, the crotch strap hole 37 being provided through the seat cushion body 31. Wherein the crotch strap aperture 37 extends through the upper and lower surfaces 31a, 31b of the seat cushion body 31, i.e. the crotch strap aperture 37 has a crotch strap outlet 37a located on the upper surface 31a and a crotch strap inlet 37b located on the lower surface 31 b. One end of the crotch strap 41 is located on the lower surface 31b and the other end passes out of the upper surface 31a through the crotch strap aperture 37. With continued reference to fig. 12, the crotch strap aperture 37 communicates with the guide recess 317 on the lower surface 31b of the seat cushion body 31, specifically, the crotch strap inlet 37b is located at the bottom wall of the guide recess 317. Wherein the number of crotch strap holes 37 is two, the crotch strap holes 37 are distributed in the first direction D1 to allow the crotch strap holes 37 through which the crotch strap 41 is to be threaded to be selected according to the body shape of the child. In other embodiments, the number of crotch strap holes 37 may be set to one or more than two, without limiting the application.

As shown in fig. 12, in an embodiment, the crotch strap aperture 37 is offset from the storage recess 314, i.e., at least one of the crotch strap inlet 37b and the crotch strap outlet 37a of the crotch strap aperture 37 is not in communication with the storage recess 314. As shown in connection with fig. 10, in this embodiment, the crotch strap outlet 37a is provided offset from the cover 33 (i.e., the crotch strap outlet 37a is not provided on the cover 33).

In another embodiment, as shown in FIGS. 27 and 28, crotch strap holes 37 extend through the cover 33 and communicate with the storage recess 314. Specifically, the crotch strap aperture 37 is located in the first cover portion 33d. The crotch strap outlet 37a is located in the upper cover 33a, and the crotch strap inlet 37b is located in the lower cover 33 b. Thus, when the crotch strap 41 is not used, the crotch strap 41 can be directly received in the storage recess 314.

As shown in fig. 7, 11 and 12, in one embodiment, the child booster seat 3 is further provided with shoulder strap adjustment holes 318. The shoulder strap adjustment hole 318 is used for the adjustment strap 42 to pass out to adjust the effective length of the shoulder strap 43. The child safety seat 100 is also provided with an adjustment mechanism 35, at least a portion of the adjustment mechanism 35 being disposed in the seat cushion body 31 and at least partially received within the shoulder strap adjustment aperture 318. The adjustment mechanism 35 is connected to the adjustment strap 42 to adjust and lock the effective length of the shoulder strap 43. Referring to fig. 10 in combination, at least a portion of the adjustment mechanism 35 is located on the upper surface 31a of the seat cushion body 31 and on the front end 31c of the seat cushion body 31 to facilitate operation of the adjustment mechanism 35. The lower surface 31b of the seat cushion body 31 is provided with a guide recess 317, the guide recess 317 extending from the rear end 31D to the front end 31c of the seat cushion body 31, the direction of extension of the guide recess 317 being substantially parallel to the first direction D1. In the present embodiment, the guide recess 317 is located between the two first groove portions 3111, and the shoulder strap adjustment hole 318 communicates with the accommodation chamber 303. One end of the shoulder strap adjustment hole 318 is located on the upper surface 31a, the other end of the shoulder strap adjustment hole 318 is located on the bottom wall of the second groove portion 3112 of the engagement groove 311, and the shoulder strap adjustment hole 318 communicates with the guide recess 317. The adjustment mechanism 35 is at least partially mounted to the upper surface 31a of the seat cushion body 31. The cross bar 23 is provided with a mounting portion 235, and the adjustment mechanism 35 is connected to the mounting portion 235 through a shoulder strap adjustment hole 318. The adjustment strap 42 can extend along the guide recess 317 and be connected to the adjustment mechanism 35 through the shoulder strap adjustment aperture 318. The adjustment mechanism 35 has a locked state and an unlocked state, and when the adjustment mechanism 35 is in the unlocked state, the adjustment strap 42 is capable of bi-directional movement relative to the adjustment mechanism 35, so that the effective length of the shoulder strap 43 can be increased or decreased. When the adjustment mechanism 35 is in the locked state, the adjustment strap 42 is only movable in one direction relative to the adjustment mechanism 35, so that the effective length of the shoulder strap 43 can be reduced by pulling the adjustment strap 42.

Fig. 21 shows a schematic structural diagram of an adjusting mechanism 35 according to another embodiment of the present application.

In another embodiment, as shown in fig. 21, the child safety seat 100 further includes an adjustment mechanism 35.

The adjustment mechanism 35 includes a belt lock assembly 351 and a belt adjustment release 352. Referring to fig. 24 in combination, a belt lock assembly 351 is provided on the cross bar 23 for passing the adjustment belt 42 of the seat belt 4 therethrough and locking the adjustment belt 42 of the seat belt 4, and has a locked state and an unlocked state. The adjuster belt 42 is movable in one direction with respect to the belt lock assembly 351 in a direction to tighten the shoulder belt 43 of the seat belt 4 when the belt lock assembly 351 is in the locked state, and the adjuster belt 42 is movable in both directions with respect to the belt lock assembly 351 in a direction to tighten and loosen the shoulder belt 43 of the seat belt 4 when the belt lock assembly 351 is in the unlocked state.

Referring to fig. 21, the seat belt adjusting and releasing lock 352 is movably provided to the child booster seat 3, and specifically, the seat belt adjusting and releasing lock 352 is movably provided to the cover 33. The belt adjustment release 352 is detachably connected to the belt locking assembly 351, i.e. it corresponds to the belt adjustment release 352 being connected to the belt locking assembly 351 in a driving manner and the two being detachable from each other. The seat belt adjusting release 352 has an operating section 3523a and a driving end section 3522, the operating section 3523a being exposed at the upper surface 31a of the child booster seat 3, the driving end section 3522 being located at the lower surface 31b of the child booster seat 3, the operating section 3523a being operable to allow the seat belt locking assembly 351 to be switched from the locked state to the unlocked state by the driving end section 3522 pushing against the seat belt locking assembly. Specifically, the seat belt adjusting release lock 352 is pivotally connected to the seat cushion body 31 of the child booster seat cushion 3 by a pivot shaft 3521, and the pivot shaft 3521 is connected to an end of the operating section 3523a remote from the driving end 3522. In this embodiment, the belt adjustment release 352 is an integrally formed member. The upper surface of the operation section 3523a forms a concave pressing recess 3523, and the pivot shaft 3521 is connected to the lower surface of the operation section 3523 a. The pressing recess 3523 and the driving end 3522 are both located on the same side of the pivot shaft 3521. When the pressing recess 3523 is pressed downward, the driving end 3522 rotates about the pivot shaft 3521 and pushes against the belt locking assembly 351. As shown in fig. 31 and 32, the webbing adjusting lock release 352 is located between the two opening and closing mechanisms 39 (i.e., the opening and closing lock release 391).

The locking seat 3511 is fixedly disposed on or integrally formed with the cross bar 23. A torsion spring (not shown in the drawings) is provided between the locking seat 3511 and the locking block 3512. When the webbing adjustment release member 352 is operated, the driving end portion 3522 rotates about the pivot shaft 3521 and pushes against the lock block 3512 to rotate, so that the adjustment mechanism 35 is switched from the locked state to the released state. When the release lock 352 is not operated, the lock block 3512 rotates to the initial position by the elastic restoring force of the torsion spring, and in the process, the lock block 3512 pushes the seat belt adjustment release lock 352 to rotate to the initial position.

Fig. 48 shows a schematic structural view of an adjusting mechanism 35 according to another embodiment of the present application. The adjustment mechanism 35 in this embodiment differs from the adjustment mechanism 35 in the embodiment shown in fig. 21 described above at least in the following.

As shown in fig. 35, 46 to 48, the adjustment mechanism 35 includes a webbing lock assembly 351 and a webbing adjustment release lock 352. The belt lock assembly 351 may be referred to in the above-described other embodiment, and will not be described in detail herein. The webbing adjustment release lock 352 is movably provided on the cover 33. The webbing adjustment release lock 352 moves substantially in the up-down direction, that is, the webbing adjustment release lock 352 moves substantially in the direction perpendicular to the upper surface 31a of the seat cushion main body 31. The cover 33 is provided with a penetration passage 336, and the penetration passage 336 is provided to penetrate the upper cover 33a and the lower cover 33 b. The upper cover 33a and the lower cover 33b form two outlets of the penetration passage 336, respectively. The seat belt adjustment release 352 has an operating section 3523a and a drive end 3522. The operating section 3523a is exposed to the upper surface 31a of the child booster seat 3 through an outlet in the upper cover 33a, and the driving end 3522 can protrude from the lower surface 31b of the child booster seat 3 through an outlet in the lower cover 33 b. In this embodiment, the belt adjustment release 352 is an integrally formed member. The upper surface of the operation section 3523a forms a concave pressing recess 3523. The operation section 3523a is provided with a first limiting portion 3524, the penetrating channel 336 is provided with a second limiting portion 3361, and the second limiting portion 3361 is disposed on the upper cover 33a and located at the opening of the upper cover 33 a. The first limiting portion 3524 is adapted to abut against the second limiting portion 3361 to limit the seat belt adjusting release lock 352 at least partially in the through passage 336, so as to prevent the seat belt adjusting release lock 352 from being pulled out of the through passage 336. The driving end 3522 is provided with a limiting hook 3525, and a limiting recess 3363 is provided on a side wall of the through passage 336, and the limiting recess 3363 is provided at an outlet of the lower cover 33 b. The limiting hook portion 3525 is adapted to engage with the limiting recess 3363 to prevent the seat belt adjusting release lock 352 from being disengaged from the through-passage 336.

When the webbing adjustment release lock 352 is operated, the webbing adjustment release lock 352 moves downward, and the driving end 3522 protrudes out of the penetrating passage 336 and rotates against the lock block 3512 of the webbing locking assembly 351, so that the adjustment mechanism is switched from the locked state to the release state, and the adjustment webbing 42 can be adjusted bi-directionally.

Referring to fig. 48, the adjusting mechanism 35 further includes an adjusting and resetting member 353, and the adjusting and resetting member 353 is disposed in the penetrating passage 336 and abuts against the operating section 3523a of the seat belt adjusting and releasing member 352. The adjustment return member 353 provides a force to the webbing adjustment lock release member 352 to return the webbing adjustment lock release member 352 to the initial position, so that the adjustment mechanism 35 is switched from the lock release state to the lock state. Specifically, when the webbing adjusting lock release member 352 is not operated, the webbing adjusting lock release member 352 moves toward the initial position by the adjusting return member 353, the driving end portion 3522 no longer pushes against the lock block 3512 of the webbing locking assembly 351, and the lock block 3512 is rotationally returned by the torsion spring, so that the adjusting mechanism 35 is switched to the locked state. In this embodiment, the adjustment restoring member 353 is, for example, a compression spring. The penetrating channel 336 is provided with a first boss 3362, the operating section 3523a is provided with a second boss 3526, and the first boss 3362 is disposed opposite to the second boss 3526. One end of the adjusting reset piece 353 is sleeved on the first boss 3362, and the other end is sleeved on the second boss 3526 and is abutted against the operation section 3523 a. This prevents the return adjustment member 353 from being deflected during elastic energy storage.

The present application also provides a reclining device that may be configured on the child safety seat 100.

As can be seen from the above, in some embodiments the child safety seat 100 is also provided with a recline mechanism 5. The inclination angle θ of the backrest module 2 to the base 9 (i.e., the inclination angle θ of the backrest main body 21 with respect to the base 9) can be adjusted by adjusting the inclination adjusting means 5.

In another embodiment, as shown in fig. 21 and 22, the recliner 5 is connected between the base 9 and the seat assembly 10 wherein at least a portion of the recliner 5 is located between the base 9 and the mating rib 22. The reclining device 5 has a locked state and an unlocked state, and the reclining device 5 includes an engagement mechanism 51 and an operating assembly 520, the engagement mechanism 51 being connected between the base 9 and the mating rib 22 and being switchable between a locked position and an unlocked position. The operating unit 520 is drivingly connected to the locking mechanism 51, and the operating unit 520 is operable to drive the locking mechanism 51 from the locked position to the unlocked position. When the engagement mechanism 51 is in the unlock position, the reclining device 5 is in the unlock state, the engagement rib 22 of the backrest module 2 is allowed to slide with respect to the base 9, so that the reclining angle θ of the backrest body 21 with respect to the base 9 can be adjusted, and when the engagement mechanism 51 is in the lock position, the reclining device 5 is in the lock state, the engagement rib 22 is restricted from sliding with respect to the base 9, so that the reclining angle θ of the backrest body 21 with respect to the base 9 is locked.

In another embodiment, as shown in fig. 21 and 22, the tilt adjustment device further includes a catch 53. The engagement mechanism 51 is pivotably provided to one of the seat assembly 10 and the base 9 and is provided with an engagement lever 511. The engaging piece 53 is provided to the other of the seat assembly 10 and the base 9, and a plurality of engaging recesses 531 are provided in order in the front-rear direction. Wherein the engagement lever 511 is selectively engageable with one of the plurality of engagement recesses 531 to limit the seat assembly 10 to a desired angle, and the seat assembly 10 is movable relative to the base 9 in a fore-aft direction when the engagement mechanism 51 is pivoted to disengage the engagement lever 511 from the plurality of engagement recesses 531. In the present embodiment, as shown in connection with fig. 24 to 26, the click mechanism 51 is pivotably provided to the seat assembly 10, specifically, the click mechanism 51 is pivotably connected with the mating rib 22. The fastening piece 53 is fixedly arranged on the base 9. When the engagement lever 511 engages the engagement recess 531 at the rearmost side of the base 9, the angle θ between the back assembly 2 and the base 9 is greatest (i.e., the seat assembly 10 is in the upright position). When the engagement lever 511 engages the engagement recess 531 at the forefront of the base 9, the angle θ between the back assembly 2 and the base 9 is minimized (i.e., the seat assembly 10 is in the lie flat position). Of course, the engagement mechanism 51 may be provided on the base 9 and the engagement member 53 may be provided on the seat assembly 10, as desired. In other embodiments not shown, the engaging members 53 may not be provided, but a plurality of engaging recesses 531 may be provided directly on the base 9 or the seat assembly 10, which is not a limitation of the present application.

Referring to fig. 21 and 30, in another embodiment, an operating assembly 520 is movably provided on the seat body 1. The seat body 1 is, for example, a child booster cushion 3. The operating assembly 520 includes a first operating member 52, a second operating member 56, and an operating reset member 54. The second operating member 56 is movably disposed on the seat body 1, the first operating member 52 is movably disposed on the seat body 1 and is in driving connection with the driving member 512 of the engaging mechanism 51, and the moving direction of the second operating member 56 is parallel to the moving direction of the first operating member 52. The second operating member 56 is connected to the first operating member 52 and operable to move the first operating member 52 to drive the engagement mechanism 51 from the locked position to the unlocked position. Referring to fig. 23 in combination, the first operating member 52 is generally U-shaped. The first operating element 52 is movably provided in the seat body 1, and has an operating portion 521 and an operating driving portion 522 connected to both ends of the operating portion 521, the operating portion 521 is connected to the second operating element 56, and the operating driving portion 522 is drivingly connected to the engagement mechanism 51. When the second operating member 56 is operated, the first operating member 521 is moved in the seat body 1 by the operating portion 521, and the operation driving portion 522 of the first operating member 521 drives the engagement mechanism 51 to rotate about the pivot axis X (see fig. 24) with respect to the engagement rib 22, thereby rotating the engagement mechanism 51 from the lock position to the release position. In the present embodiment, the seat body 1 is provided with the operation notch 3103, and the operation notch 3103 is located at the front end 31c of the seat body 1 and at the lower surface 31b of the seat body 1. The second operating member 56 is located at the operating notch 3103. This allows both the second operating member 56 to be conveniently operated via the operating notch 3103 and the second operating member 56 to be prevented from interfering with a child seated in the seat body 1, while also preventing the child from accidentally moving the second operating member 56.

As shown in fig. 21, an operation return member 54 is provided between the first operation member 52 and the seat body 1, and the operation return member 54 is adapted to bias the first operation member 52 to move the first operation member 52 toward the initial position. When the first operating element 52 is in the initial position, the tilt adjusting device 5 is in the locked state, and the engagement mechanism 51 is in the locked position. In the present embodiment, the operation resetting member 54 is, for example, a compression spring. The operation resetting piece 54 is located in the seat body 1, one end of the operation resetting piece 54 abuts against the seat body 1, the other end of the operation resetting piece 54 abuts against the first operation piece 52, and specifically, the other end of the operation resetting piece 54 abuts against the operation portion 521 of the first operation piece 52.

As shown in fig. 22 and 24 to 26, in another embodiment, the locking mechanism 51 includes a locking lever 511 and two driving members 512 connected to the locking lever 511, and the two driving members 512 and the locking lever 511 together form a substantially U-shaped structure. The two driving members 512 are pivotally connected to the corresponding mating ribs 22 by the connection pins 501, respectively, and specifically, the driving members 512 are pivotally connected to the rib housings 227 of the corresponding mating ribs 22 by the connection pins 501. The driving member 512 is substantially L-shaped. The driving member 512 has a first driving end 5121 and a second driving end 5122, the first driving end 5121 extending upward in a substantially vertical direction (i.e., up-down direction), and the second driving end 5122 extending in a substantially horizontal direction (i.e., front-rear direction). Referring to fig. 22, the first driving end 5121 is drivingly connected to the operation driving portion 522 of the first operation element 52. Specifically, the operation driving portion 522 is provided with a driving groove 523, and the first driving end 5121 is inserted into the driving groove 523. The end of the drive slot 523 is capable of pushing against the first drive end 5121, thereby driving the drive member 512 in rotation about the connection pin 501 (i.e., the pivot axis X). Referring to fig. 29 and 30 in combination, in the present embodiment, the operation driving portion 522 is located in the seat body 1, the lower surface 31b of the seat body 1 is provided with the penetration hole 31b1, and the first driving end 5121 is extended into the seat body 1 through the penetration hole 31b1 and is penetrated into the driving groove 523. Of course, in other alternative embodiments, the first operating member 52 may operate the driving portion 522 to protrude below the seat body 1 through the insertion hole 31b1, and the first driving end 5121 may be inserted into the driving slot 523 of the first operating member 52.

Referring to fig. 22 and 23, in another embodiment, the driving slot 523 is elongated and extends along the moving direction of the first operating member 52, such that the end of the driving slot 523 will push the first driving end 5121 (i.e., corresponding to providing a certain amount of idle stroke for the second operating member 56) only when the moving distance of the first operating member 52 (i.e., the second operating member 56) reaches a certain value, so as to avoid the accidental switching of the tilt adjusting apparatus 5 to the unlocked state due to the false touch, and particularly, to avoid the accidental unlocking of the tilt adjusting apparatus 5 due to the false touch when the child sits on the child safety seat 100, thereby improving the safety of the child safety seat 100. As shown in fig. 22, in the present embodiment, the first driving end 5121 forms a limit hook 5124, and the limit hook 5124 is locked with the end of the driving slot 523, so as to avoid accidental separation of the end of the driving slot 523 and the first driving end 5121 when the two are pushed against each other.

As shown in fig. 22 and 24, the engagement lever 511 extends in a substantially right-left direction (i.e., perpendicular to the first direction D1). To limit the pivot stroke of the locking mechanism 51, at least one of the engaging ribs 22 is provided with a limiting groove 224, and at least one end of the locking lever 511 is inserted into the limiting groove 224, and the limiting groove 224 is, for example, arc-shaped or elongated. The engaging rod 511 is fixed or movably connected to the driving member 512. In the present embodiment, the locking lever 511 is movably connected to the second driving end 5122 of the driving member 512, and the locking lever 511 passes through the second connecting hole 5123 provided on the second driving end 5122 and is inserted into the limiting groove 224 provided on the rib body 22. Both the two matching ribs 22 are provided with limiting grooves 224, and both ends of the clamping rod 511 respectively penetrate into the limiting grooves 224.

With continued reference to fig. 22 and 24, the second connection hole 5123 is elongated, and the limiting groove 224 is elongated. The extending direction of the second connection hole 5123 and the extending direction of the limit groove 224 are intersected with each other. Specifically, the extending direction of the second connection hole 5123 forms an angle of approximately 90 degrees with the extending direction of the limiting groove 224, the second connection hole 5123 extends approximately along the front-rear direction, and the limiting groove 224 extends approximately along the up-down direction. Thus, when the driving member 512 is driven to rotate, the locking lever 511 can be driven to rotate around the pivot axis X. Of course, in other embodiments, the limiting groove 224 and the second connection hole 5123 may have other shapes, as long as the engaging lever 511 can be rotated about the pivot axis X within a set stroke. Referring again to fig. 24, in the present embodiment, the limit groove 224 is formed in the rib housing 227 of the mating rib 22. Specifically, the limit groove 224 is formed on the inner housing 227 b.

As shown in fig. 22 and 24, in another embodiment, the locking mechanism 51 further includes a locking reset member 513, wherein the locking reset member 513 is disposed between the engaging rib 22 and the driving member 512, and the locking reset member 513 is adapted to bias the driving member 512 to rotate the locking mechanism 51 in the direction of the locking position. Specifically, the engagement return member 513 is, for example, a torsion spring. The engaging reset member 513 is sleeved on the connecting pin 501 on the matching rib 22, one end of the engaging reset member 513 is abutted against the matching rib 22, and the other end is abutted against the driving member 512.

In the above-described other embodiment, the operation principle of the inclination adjustment device 5 for angle adjustment is as follows.

Referring to fig. 21, when it is desired to adjust the angle of the seat assembly 10 relative to the base 9, the second operating member 56 is pulled forward in the front-rear direction (i.e., in the first direction D1), and the second operating member 56 moves the first operating member 52 forward. When the first operating member 52 is moved to push the end of the driving slot 523 against the first driving end 5121 of the driving member 512, the end of the driving slot 523 drives the first driving end 5121 to rotate in a counterclockwise direction about the pivot axis X (see fig. 24) and the second driving end 5122 of the driving member 512 to rotate in a counterclockwise direction about the pivot axis X. Since the locking lever 511 is connected to the second driving end 5122, the second driving end 5122 drives the locking lever 511 to rotate around the pivot axis X in the counterclockwise direction, that is, the locking lever 511 moves upward relative to the base 9, so that the locking lever 511 is separated from the locking recess 531 (that is, the locking lever 511 and the locking recess 531 are not locked), and the engaging rib 22 can move in the front-rear direction relative to the base 9.

When the seat assembly 10 is adjusted to a desired angle, the second operating member 56 is released, the operating portion 521 moves backward under the elastic restoring force of the operating restoring member 54, the end portion of the driving slot 523 of the first operating member 52 no longer pushes against the first driving end 5121 of the driving member 512, and the driving member 512 rotates clockwise about the pivot axis X under the elastic restoring force of the engaging restoring member 513, and drives the second driving end 5122 of the driving member 512 to rotate clockwise about the pivot axis X. Since the locking lever 511 is connected to the second driving end 5122, the second driving end 5122 drives the locking lever 511 to rotate about the pivot axis X in a clockwise direction, that is, the locking lever 511 moves downward relative to the base 9, so that the locking lever 511 is locked with the locking recess 531, thereby locking the seat assembly 10 at a desired angle. Whereby angular adjustment of the seat assembly 10 can be achieved.

Fig. 35 illustrates a perspective view of a child safety seat 100 provided in accordance with yet another embodiment of the present application.

The child safety seat 100 in this embodiment differs from the child safety seat 100 in the other embodiment described above and shown in fig. 19 at least in the following.

As shown in fig. 35-37, the recliner 5 is connected between the base 9 and the seat assembly 10 wherein at least a portion of the recliner 5 is located between the base 9 and the mating rib 22 of the back assembly 2. The reclining device 5 includes an engagement mechanism 51 and an operating assembly 520, the engagement mechanism 51 being connected between the base 9 and the mating rib 22 and being switchable between a locked position and an unlocked position. The operating unit 520 is drivingly connected to the locking mechanism 51, and the operating unit 520 is operable to drive the locking mechanism 51 from the locked position to the unlocked position. The operating assembly 520 is movably disposed on the seat body 1 (i.e., the child booster seat cushion 3). The engagement mechanism 51 includes an engagement lever 511, a driving member 512 connected to the engagement lever 511, and an engagement piece 53 provided with an engagement recess 531. The driving member 512 is pivotally connected to the two mating ribs 22 by the connecting pin 501. The engaging rod 511 is disposed through the driving member 512 and can pivot with the driving member 512. Alternatively, the driving member 512 is pivoted to the two mating ribs 22 through one connecting pin 501, or the driving member 512 is pivoted to the corresponding side mating rib 22 through two connecting pins 501, and the two connecting pins 501 are coaxially disposed.

Referring to fig. 36 and 37, the driver 512 is located between the two mating ribs 22. The driving member 512 includes a driving body 5125, a first driving end 5121 and a second driving end 5122, the first driving end 5121 and the second driving end 5122 being connected to both ends of the driving body 5125, respectively, specifically, the first driving end 5121 and the second driving end 5122 being connected to both front and rear ends of the driving body 5125, respectively. Wherein the first driving end 5121 extends upward in a substantially vertical direction (i.e., up-down direction). The second driving end 5122 extends substantially in the front-rear direction. In other words, the angle between the line between the first drive end 5121 and the pivot axis X of the drive member 512 and the line between the second drive end 5122 and the pivot axis X is substantially 90 °. Alternatively, the number of the first driving ends 5121 is two, and the number of the second driving ends 5122 is two. In other embodiments, the number of first driving ends 5121 may be greater than two or may be one. Likewise, the number of the second driving ends 5122 may be more than two or may be one. Returning to fig. 37, two first driving end portions 5121 are disposed on the left and right sides of the driving body 5125, respectively, and two second driving end portions 5122 are disposed on the left and right sides of the driving body 5125, respectively. Specifically, the two first driving end portions 5121 and the two second driving end portions 5122 are symmetrically disposed at the left and right sides of the driving body 5125, so that the stress of the driving member 512 can be more balanced and uniform. More specifically, in the left-right direction, the first driving end 5121 and the second driving end 5122 disposed on the same side of the driving body 5125 are located between the corresponding mating rib 22 and the catch 53, respectively. The engaging rods 511 are provided to pass through the two first driving end portions 5121. At least one end of the locking lever 511 may pass through the first driving end 5121 and into the limiting groove 224 of the engaging rib 22. The engaging lever 511 is rotatable with the driving member 512 relative to the limiting groove 224, and the rotational stroke of the engaging lever 511 can be limited by the stopping action of the end of the limiting groove 224 on the engaging lever 511.

The driving body 5125 has a substantially plate shape. The first driving end 5121 is integrally formed on the driving main body 5125, or fixedly arranged on the driving main body 5125 by means of bonding, welding or the like, or arranged on the driving main body 5125 by means of clamping or the like, and the first driving end 5121 protrudes upwards from the driving main body 5125. The second driving end 5122 is integrally formed on the driving body 5125, or is fixedly disposed on the driving body 5125 by bonding, welding or the like, or is disposed on the driving body 5125 by clamping or the like, and the second driving end 5122 protrudes backward from the driving body 5125. The driving body 5125 includes a first driving connection part 51251 and a second driving connection part 51252. The first driving connection part 51251 is connected between the two first driving end parts 5121, so that the stress of the driving member 512 can be more balanced. The second driving connection portion 51252 is closer to the locking lever 511 than the first driving connection portion 51251, and the second driving connection portion 51252 is located between the pivot axis X and the locking lever 511. An operation hole 51253 is formed between the first driving connection portion 51251 and the second driving connection portion 51252, so that the second driving connection portion 51252 is pulled by the operation hole 51253 to rotate the driving member 512, thereby driving the engaging lever 511 to rotate. Thus, when the seat body 1 (i.e., the child booster seat cushion 3) is not mounted on the backrest module 2, the second drive connection 51252 is operated to rotate the driving element 512, thereby adjusting the angle θ between the backrest module 2 and the base 9. In this embodiment, a space is formed between the engaging lever 511 and the driving member 512, so that the second driving connection part 51252 is more convenient to hold.

As shown in fig. 49 to 50, the child safety seat 100 is further provided with a seat cloth pad 8. The cloth pad 8 includes a second cloth pad 81 and a first cloth pad 82. One end of the first cloth pad 82 is connected to the child booster seat 3 or the second cloth pad 81 and serves as a pivot end 823 to allow the first cloth pad 82 to be flipped between the covering position and the flipped-up position. The second cloth pad 81 is provided with a relief recess 811, and when the second cloth pad 81 is provided on the child booster seat 3, the position of the relief recess 811 is opposite to the position of the cover 33. In this way, the cover 33 can be opened or closed by the escape recess 811 without detaching the seat cushion 8. Specifically, the relief recess 811 is substantially U-shaped, and the opening of the relief recess 811 faces the backrest main body 21. The second cloth pad 81 is provided with a handrail sleeve portion 812, and the handrail sleeve portion 812 is used for being sleeved on the second handrail portion 34b at the rear side of the first sleeve hole 36, so that the second cloth pad 81 can be conveniently installed on the child height-increasing seat cushion 3, and displacement of the second cloth pad 81 is avoided. In the present embodiment, the second cloth pad 81 is provided with a first engaging portion 833, and the child booster seat 3 is provided with a second engaging portion 337, and the first engaging portion 833 is adapted to be detachably connected with the second engaging portion 337, thereby detachably disposing the second cloth pad 81 on the child booster seat 3. Alternatively, one of the first mating portion 833 and the second mating portion 337 is, for example, a button body, a protrusion, or a hanging button, and the other of the first mating portion 833 and the second mating portion 337 is, for example, a button hole, or a hanging ring. Or the first engaging portion 833 and the second engaging portion 337 are snap fasteners or velcro fasteners that can be engaged with each other.

When the first cloth pad 82 is in the covering position, the first cloth pad 82 covers the avoidance recess 811 of the second cloth pad 81 and covers the cover 33, and the second cloth pad 81 and the first cloth pad 82 together cover the child booster seat 3, so that the child booster seat 3 provides a relatively soft and comfortable seating surface. When the first cloth pad 82 is located at the open position, the cover 33 is exposed from the escape recess 811 to allow the operation cover 33 to be switched between the open state and the closed state. By the first cloth pad 82 being provided on the child booster seat 3 in a reversible manner, the cover 33 can be switched between the open state and the closed state without detaching the seat cloth pad 8, so that the article (e.g., the connecting belt assembly 7) stored in the storage recess 314 can be more conveniently taken or used. Referring to fig. 49 to 50, the pivot end of the first cloth pad 82 is connected to the seat cushion main body 31 of the child booster seat cushion 3, and the rotation direction of the first cloth pad 82 from the closed position to the open position is the same as the rotation direction of the cover 33 from the closed state to the open state. Specifically, the pivot end of the first cloth pad 82 is connected to the seat cushion body 31 at a position near the first side 331. More specifically, the pivot end is located behind the first side 331, that is, corresponds to a position of the seat cushion body 31 between the first side 331 and the back main body 21. The pivot end of the first cloth pad 82 defines a pivot axis S of the second cloth pad. As shown in connection with fig. 27 and 28, the pivot axis S of the first cloth pad 82 is located rearward of the second set of apertures 348 of the armrest portion 34. That is, the pivot axis S of the first cloth pad 82 is closer to the backrest main body 21 than the second sleeve hole 348. This prevents interference between the first cloth pad 82 and the connector strap assembly 7 that may be threaded through the second sleeve hole 348. The relief recess 811 of the second cloth pad 81 opens toward the pivot axis S. The first cloth pad 82 is further provided with crotch strap perforations 821 for passing out crotch strap 45 (see fig. 19). When the first cloth pad 82 is in the covering position, the crotch strap aperture 821 is substantially aligned with the crotch strap aperture 37. The number of crotch strap perforations 821 corresponds to the number of crotch strap holes 37. With continued reference to fig. 49-50, the first cloth pad 82 is also provided with an adjustment aperture 822, the adjustment aperture 822 being for a user to operate the adjustment mechanism 35. When the first cloth pad 82 is in the covering position, the adjustment opening 822 is aligned with the belt adjustment release 352 of the adjustment mechanism 35 to allow the belt adjustment release 352 to be operated through the adjustment opening 822.

The first cloth pad 82 is detachably connected with the second cloth pad 81. The second cloth pad 81 is provided with a first connecting member 831, the first cloth pad 82 is provided with a second connecting member 832, and the second connecting member 832 is adapted to be detachably connected with the first connecting member 831. Alternatively, the first connecting piece 831 and the second connecting piece 832 are, for example, velcro tapes that can be adhered to each other. The second link 832 is disposed at an end of the second cloth pad remote from the pivoting end 823, and the position of the first link 831 corresponds to the position of the second link 832. Through the cooperation of the first connecting piece 831 and the second connecting piece 832, the second cloth pad 81 and the first cloth pad 82 can be connected together, and the second cloth pad 81 is prevented from being deviated or folded, etc.

In an embodiment not shown, the second cloth pad 81 may not be provided. The pivot end 823 of the first cloth pad 82 is attached to the seat pad body 31. The end of the first cloth cushion 82 remote from the pivot end 823 has a second connector 832, and the seat cushion body 31 is correspondingly provided with a first connector 831. In this way, the first cloth pad 82 may be disposed on the seat pad main body 31 in a reversible manner, and the first cloth pad 82 may be fixed on the seat pad main body 31 by detachably connecting the first connecting member 831 and the second connecting member 832 when the first cloth pad 82 is located at the covering position.
