technical field

The present application relates generally to a vehicle seat for an automobile for transporting a child, and more particularly, to a headrest of a vehicle seat that can be adjusted in position to comfortably and safely support the child.

Background technique

Car seats for children are commercially available in a variety of configurations, corresponding to the age, weight and height of the children being transported. Parents can choose a vehicle seat that is not only the right size, but also fits their taste, budget and lifestyle. As children grow in size and developmental level, they need different types of vehicle seats. For example, a child initially uses a rear-facing infant car seat, progresses to a forward-facing toddler car seat with integral shoulder straps, and finally uses a A booster vehicle seat positioned by a shoulder harness that utilizes an automobile's seat belt and shoulder harness system.

There are many car seats on the market that can be used in a variety of configurations. For example, a forward-facing seat for a child of 20-40 lbs with integral shoulder straps could remove the straps and utilize the car's seat belt and shoulder harness system to serve as a shoulder strap positioning booster seat to accommodate a weight of Children 30-100 lbs. This makes it easier for guardians to purchase fewer seats. Some parents choose to purchase shoulder strap positioning booster seats for their older children. These booster seats may be configured with a high back, as disclosed in US Patent No. 6,682,143, issued January 27, 2004 to Davis Amirault, or may have no seat back at all. Older children don't want to be seen sitting in a "baby seat" like this option, and parents don't have to manage a large, bulky car seat.

Seats available today typically have a one-piece shell, that is, the seat back and seat cannot be used separately. Some automotive seats are designed without a back base, but instead are configured as a separate seat secured under the integral seat and back, as in U.S. Patent No. 4,754,999 issued to James Kain on July 5, 1998 revealed in. The problem with this configuration is that there are redundant seats; one as part of the overall shell and one as only the seat.

Check condition and adjust limiter age and weight specifications. As the car restraint safety increases with age and weight, various restraint sizes are required to accommodate the increasing span of the car seat safety restraint required by the child. Shoulder height and proper placement of the shoulder strap trajectory are critical to the safety of the car seat restraint. As children grow, the area of the headrest needs to fit the size of their body and move up as they grow. Some seats are used for more than one child and the headrest area needs to be moved up and down to fit each child. Buying new seats as children grow is an expensive option. Some seats on the market have up and down headrest adjustments, but they are often not obvious or easy to operate. An example of such a car seat with an adjustable headrest can be found in U.S. Patent No. 6,623,074 issued to Ronald Asbach in 2003, wherein the headrest can be moved vertically on the adjust. Another example can be found in US Patent Application No. 2005/0225136 filed by William Horton and published on October 13, 2005, where the headrest is movable vertically relative to the seat back.

Children often fall asleep while in a car seat. As a result their heads fall forward and are not adequately supported. The side supports on some child safety seats are not only angled too far out to support the head or position properly, but are rigid and immovable, as in the aforementioned US Patent No. 6,623,074 and US Patent Application No. 2005/0225136 described inside. The side supports need to be moved in and out to accommodate different head sizes. The side supports need to be able to move in to support the head while the child is sleeping, and then move out rearward to provide comfort and visibility for the child while driving. Side supports alone are not a solution to prevent children from falling head forward when they are asleep. The child can support their head to one side, but the movement of the vehicle will cause the child's head to fall forward and vibrate uncomfortably.

In U.S. Patent No. 6,481,794 issued to Kenzou Kassai on November 19, 2002, a car seat with a sleep support position controller is disclosed, comprising a bearing provided on the headrest and a shaft provided on the sleep post pole. The concave portion provided on the lower surface of the bearing is engaged with the convex portion provided on the upper surface of the shaft, and a coil spring is embedded at a height to maintain the engaged state with an elastic force, thereby fixing the position of the sleeping support. U.S. Patent No. 7,055,903 issued June 6, 2006 to Eugene Balensiefer discloses an adjuster for a car seat that includes a disc brake attached to the back post for movement relative to the back post. The rotational movement activates the lock/unlock mechanism of the height adjustment mechanism and allows the headrest to move freely up and down relative to the seat frame. In U.S. Patent No. 6,464,294 issued to James Kain on October 15, 2002, a car seat is disclosed, which has a forward surface facing the occupant in the seat, and The surface has a groove. The headrest anchor is located within the headrest recess and is configured to secure the headrest in one of a user-selected raised position and lowered position relative to the seat back.

Headrests for automobiles are also vertically adjustable and have positionable wing members, such as U.S. Patent No. 6,068,337 issued to Emillio De Fillippo in 2000, which relates to an automobile headrest having a frame and a pair of Support bars slidably attached to the frame. The guide slot cooperates with a pair of arms carried by a slide member movable in the frame of the headrest, in a direction perpendicular to the support bar, between an engaged position and a disengaged position. The headrest found in U.S. Patent No. 5,806,933 issued September 15, 1998 to Leslie Tsui utilizes an elongated arm and a mounting member, wherein the mounting member has an internally indented portion that fits over the elongated arm Center radial serrated external engagement. In the European patent publication EP1136313, a position adjustment for the headrest of a car is disclosed, with a connecting mechanism, an actuating member and a connecting cable, wherein the cable exerts a force on the connecting mechanism so that the locking pin protrudes into the recess of the supporting member. slot.

US Patent No. 6,220,668 issued April 24, 2001 to Matthias Acheffziick discloses an adjustable wing for a car headrest in which an activation button is used to release the wings of the headrest from a locked position. The pivotal connection of the flanks to the central headrest is formed by a journal having a recess and a bolt arranged in the recess. U.S. Patent No. 6,305,749 issued to Richard O'Connor on October 23, 2001, and U.S. Patent No. 6,648,416 issued on November 18, 2003 disclose an automotive headrest in which the side wings are mounted by a friction hinge , the friction hinge has sufficient friction to maintain tilt with the wing member in any of a number of positions under a person's head load, but is capable of buckling when a greater load is applied.

There is a need to provide a headrest for a car seat for use in vehicles transporting children, wherein the headrest can be adjusted vertically to accommodate the growth of the child, and the side wings can be positioned with a practical range of angular coordinates for enhanced use The comfort of the child in the car seat.

Detailed ways

Referring now to FIGS. 1-3, a car seat embodying the principles of the present invention can be best seen. The car seat 10 can be configured in a conventional generally L-shaped configuration to provide a seat assembly 30 upon which the child is supported when being transported in the car, the seat assembly including an upright seat back 10 to support the child's back, there is also a vertically movable headrest 20 on the seat back to support the child's head sitting in the car seat 10.

The car seat 10 is intended to be used by a child older than an infant, and such a child is usually placed in a rear-facing infant car seat until the child is of sufficient size and age to sit in the forward-facing car seat 10, which is usually For children about one year old. However, the car seat 10 can be set in multiple orientations corresponding to the growth of the child until the child is of sufficient size and age to safely sit in the car seat using the seat belt on the car without the aid of any assistive device. superior.

Typically, toddlers and young children are placed in the traditional L-shaped configuration of the car seat 10, as shown in FIG. support. By moving the headrest 20 through multiple positions, the car seat 10 can be reconfigured to accommodate the growth of the child. Figure 1 depicts the maximum height of the headrest 20 for an older child before moving onto the booster seat.

As seen in FIGS. 1-7 , the headrest 20 includes a pair of support rails 22 received in grooves 42 formed in the top of the seat back 40 . A locking mechanism 50 is located in the headrest 20 to fix the position of the headrest 20 on the seat back 40 . Preferably, the headrest 20 includes a rear support portion 23 and a pair of wings 24 projecting forward on the rear support portion 23 and forming an angle with the side wings 44 of the seat back 40, so that when the head cover is in the lowered position, the head The backrest 20 is suitably nested along the upper portion of the seat back 40 as shown in FIG. 3 . Preferably, the wings 24 are pivotally positioned to increase the comfort of a child seated in the car seat 10, as will be described in more detail below. Accordingly, the wing 24 is connected to the rear portion 23 by a pivot shaft mechanism 60 that allows the wing 24 to be selectively positioned.

The seat back 40 has a rear support member 43 from which side wings 44 extend in a fixed unitary structure. The upper portion of the rear support member 43 includes a shoulder strap orientation device 45 comprising a plurality of pairs of orientation openings 46 positioned vertically between the grooves 42 . The shoulder strap orientation 45 allows a shoulder strap (not shown) to pass from the seat back 40 to establish a proper fit with the shoulders of a child seated in the car seat 10 . The shoulder straps will pass through a pair of selected directional openings 46 spanning from the front of the seat back 40 to the rear of the seat back 40 where a support is established on the seat back 40 for the shoulder straps passing through the seat back 40 point. The shoulder straps in turn extend upwardly from selected orientation openings 46 on the rear side of the seat back 40 . The shoulder straps then roll over the top of the hanger and extend down to the bottom of the rear support member 43 where the shoulder straps extend forward to conventional shoulder strap mounts 48 at the front of the seat assembly 30 .

Referring now to FIGS. 6-11A , there can be seen a locking arrangement 50 securing the headrest 20 in a selected vertical position relative to the seat back 40 . The locking device 50 includes an activation button 52 disposed on the upper half of the frame 21 of the headrest 20 , and the headrest 20 is formed with a handle 29 through which the headrest can be grasped. Depressing the activation button 52 into the frame 21 can best be seen in FIGS. 10 and 11 causing movement of the opposing cam member 53 supported in the frame 21 adjacent the activation button 52 . As can best be seen in FIG. 11A , the cam members 53 are connected to respective flexible members 56 which in turn are connected to a driver 55 located near the hollow support rail 22 . A biasing force is applied to the activation button 52 to move outwardly relative to the frame 21 towards the initial position by engagement with the cam member 53 which is spring loaded to return to its initial position when the activation button is retracted.

When the start button 52 and the cam member 53 are in the initial position, the respective driver 55 is close to the corresponding locking element 57, which has an outwardly protruding locking retainer 58 formed by elastic material in a cantilever manner, Moving the driver away from the locking element 57, the locking retainer 58 springs back inside the hollow support rail 22, as shown by the dashed lines in FIG. 8 . When the activation button 52 is pressed and the cam member 53 moves accordingly, the driver 55 is forcibly lowered by the elastic member 56 below the locking member 57 . The spring force and the cam member 53 drive the transmission part 55 upwardly into engagement with the locking element 57, and a cam edge on the transmission part 55 helps to initiate the movement of the locking element 57 to lock the retainer 58 via the locking element formed in the A hole 45 in a recess in the seat back 40 is pushed out, wherein the hole is used to engage a locking retainer 58 .

Therefore, the adjustment of the vertical position of the headrest 20 can be realized by pressing the activation button 52 , and the activation button 52 engages with the cam member 53 to allow the locking retainer 58 to exit the opening 45 . Once the headrest 20 has been positioned as desired, the activation button 52 is released causing the actuator 55 to rise back into engagement with the locking member 53 and drive the locking retainer 58 out through the corresponding opening 45 . In the event that the locking retainer 58 is not properly aligned with the opening 45, the spring loaded cam member 53 will maintain a force on the driver 55 until the headrest 20 is moved vertically until the locking retainer 58 is aligned with the opening, In this way, the driver 55 is moved up close to the lock retainer 58 to hold it in place, so the lock retainer 58 snaps into the opening 45 .

The channel 42 is formed with a plurality of vertically spaced openings 45 to establish a corresponding number of predetermined positions at which the headrest 20 may be positioned. In FIGS. 6 and 7 , corresponding to the position shown in FIGS. 1 and 2 , the headrest 20 is in the highest attainable position. In Fig. 8, the headrest 20 has been moved down two notches, as can be seen from the layout of the openings 45 shown in the figure. Corresponding to the position of the headrest 20 shown in FIG. 3 , the lowest position that the headrest 20 can reach is depicted in FIG. 9 . A plurality of openings 45 formed at the rear of the channel groove 42 can be seen in FIG. 9 .

Referring now to Figures 12-16A, the pivotal movement of the wings 24 can be seen. The side wings 24 facing each other are pivotally connected to the rear support portion 23 by a pivot mechanism 60, which can be seen very well from the sectional views of FIGS. 15 and 16 and the exploded view of FIG. 61 and an upper part 62. The lower portion 61 is a simple hinge arrangement that pivotally connects the mounting elements of the side wings 24 to corresponding mounting elements on the rear support. The upper portion 62 includes a latch mechanism 65 to secure the side wings 24 in the desired tilted rotational position.

A locking mechanism 65 is operatively placed between an upper mounting element 63 on the rear support 23 and a lower mounting element 64 on the side wings 24, the locking mechanism 65 comprising a release button 66 and a gear 67 inserted between the two mounting elements 63 and 64 In between, a spring 69 biases the gear 68 into engagement with the two mounting elements 63 and 64 . The release button 66 is held by a frame but is movable linearly within the frame by a vertical seat formed at the end of the actuating bracket 67 extending through the opening in the upper mounting member 63 to engage the gear 68 .

As best seen in FIG. 16, the gear 68 is biased upwardly by a coil spring 69 beneath it to engage teeth formed on both the upper and lower mounting members 63,64. When release button 66 is pressed into the frame, activation bracket 67 passes through an opening in the frame to engage gear 68 and cause the gear to resist the biasing force exerted by spring 69 . When fully depressed, the gear 68 simply engages the lower mounting element 64 , allowing the lower mounting element 64 and the side wings 24 attached thereto to rotate relative to the upper mounting element 63 and the rear support 23 of the headrest 20 . The wings 24 can be rotated to the desired position until the teeth of the upper and lower elements 63, 64 are aligned on the spring 69, at which point the gear will be pushed up into engagement with the upper mounting element 64, like the lower mounting element 63 , to lock the wings 24 into the desired pivot position.

The headrest 20 can be wrapped by the remainder of the car seat 10 removed from the seat back, thus requiring several components to complete the car seat 10 . As can be seen well in FIGS. 7 and 7A, the top of the groove 42 in the seat back 40 is widened at the rear to accommodate a head with a locking retainer 58 protruding therefrom. Lean on the bearing rail 22 of 20. The top of the seat back 40 has a mounting clip 25 mounted thereon for controlling the upward movement of the headrest 20 once mounted on the seat back 40 . The clip 25 has a bottom member 26 secured to the seat back 40 , and a spring-loaded locking catch 27 protruding therefrom and over the top of the widened portion of the groove 42 . A representative spring 28 is schematically shown to provide a bias to the locking clip 27, preferably by pressing and advancing the locking clip 27 when the locking clip 27 is retracted to provide a spring load thereon. The curved fingers of the bottom element 26 are formed.

The locking catch 27 is formed by an inclined upper surface 27a to define a cam surface capable of engaging the support rail 22 and the raised locking retainer 58, thereby urging the locking catch 27 to retract into the bottom member 26 against the spring 28. , thus allowing the support rail 22 to enter the groove 42 and cause the locking retainer 58 to protrude through the retaining clip 25 as shown in FIG. 7 . Once the locking retainer 58 has passed the clip 25, the locking clip 27 passes over the groove 42 against recoil of the locking member 57, which is detachably connected to the support rail 22 and defines a flange 22a on which the locking member 57 recoils. The upper locking catch 27 will deploy to retain the support rail 22 inside the groove 42, thus preventing the headrest 20 from being removed from the seat back.

In operation, the car seat 10 is preferably shipped to a customer with the headrest 20 detached from the seat back 40 . The headrest 20 can be mounted to the seat by sliding the support rail 22 into the receiving channel 42 at the top of the seat back 40 and pushing the locking clip 27 into the bottom member 26 until the locking retainer 58 has passed the clip 25 40 on the backrest. When the headrest 20 is assembled, the latch mechanism 50 will not be retracted by pressing the activation button 52 until the headrest 20 has been positioned on the seat back 40 at the desired height relative to the seat assembly 30 . The latching mechanism 50 extends the jam nut 58 into the opening 45 at the rear of the channel 42 to secure the headrest 20 in the desired vertical position.

Once properly secured to the car seat, the car seat 10 is ready for use. As the child grows in size, the car seat 10 is configured to accommodate the growth of the child. The headrest 20 can be reconfigured vertically to match the size of the child. Eventually, the child will grow to the stage where the shoulder harness is not needed, and while the car seat belt can provide a safe environment for the child in the seat, the child is not yet old enough for the car seat belt to fit the child properly. In this case, the car seat 40 can be moved to the highest permissible position shown in FIGS. 1 and 2 and the car seat 10 can be used as a high-back booster seat. The shoulder belt (not shown) can be passed through a shoulder belt (not shown) via a shoulder belt guide member connected to the seat 20 through a slot formed in the headrest to properly position the shoulder belt according to the position of the headrest 20. The belt part, where the position of the headrest thus corresponds to the height of the child using the seat.

Referring now to FIGS. 17 and 18 , an optional bolster 70 may be mounted to the headrest 20 to assist in the comfort of a child seated in the car seat 10 . Preferably, the pillow 70 is generally cylindrical to best conform to the shape of the wings 24 . Pillows 70 are supported on attachments 71 connected to respective side wings 24 along an inclined axis. The outboard end of the pillow 70 includes a connector 72 which is connected to the pillow 70 and extends thereto to a connector 72 which engages the side flap 24 on which the pillow 70 is mounted. The angular mounting axis of attachment 71 allows the pillow to be oriented between a substantially vertical position as shown in FIG. 17 and a substantially horizontal position as shown in FIG. 18 . Once positioned in the desired position, the connectors 72 are attached to the wings 24 to ensure that the outboard ends of the pillow do not move.

Connector 72 may comprise any conventional device, such as a hook and loop fastener or flip button, so long as the connector can be reconfigured as desired. Placing the bolster 70 in a substantially vertical position allows the child's head to rest within the car seat 10 that the bolster 70 is constructed of. When in the horizontal position, the child is able to rest the head on the bolster and prevent the head from bouncing around with the movement of the vehicle. Preferably, the attachment 71 is made of a fabric material that can be sewn to the headrest 10 covering, or can be detachably connected with conventional devices such as hook and loop fasteners or flip buttons.
