In addition, although the number of markers 21 is three in this embodiment, the number of markers 21 may be two or four or more. In addition, the mark 21 may be one (single).

The platform 30 is a member that prevents the elastic chair 1 from falling forward and sideways, and is a member that supports the seat member 10 together with the base pipe 40 . The platform 30 is provided with a groove 31, and the base frame 11a is attached to the groove 31 in a non-detachable manner. The base frame 11a is rotatable in the groove 31, and the back frame 11b rotates in the front-rear direction along with the rotation of the base frame 11a.

The base pipe 40 is a member that prevents the elastic chair 1 from falling backward and sideways, and prevents the elastic chair 1 from falling forward due to the weight of the base pipe 40 itself. The base pipe 40 is attached to the back surface portion 30 a of the stage 30 . The base pipe 40 is formed not only in a shape having a width in the front-rear direction, but also in a shape having a width in the lateral direction, for example, as shown in FIG. A shape having a certain length (width) in the lateral direction. The lateral width of the base tube 40 may also be greater than the lateral width of the seat member 10 . Rubber or resin members (not shown) are attached to the platform 30 and the base pipe 40 as a non-slip member for the installation site.

The reclining-folding mechanism portion 50 is a mechanism for changing and fixing the angle of the seat member 10 with respect to the platform 30 and the base pipe 40 . As shown in FIG. 2 , the reclining-folding mechanism portion 50 is installed in portions of the base pipe 40 that are parallel to each other. The reclining-folding mechanism part 50 has: a sliding part 51 that can move in the front-rear direction within a certain range with respect to the base pipe 40; a locking pin 52 that is urged toward the outside; and a sliding hole 53 for locking The pin 52 slides; the reclining arm 54 connects the reclining folding mechanism part 50 and the rod 11c of the seat piece 10.

In addition, the angle of the seat piece 10 is changed by the angle of the rod 11c. In this way, the angle of the seat member 10 can be changed by the position of the sliding portion 51 with respect to the front-rear direction of the base pipe 40 . With the sliding portion 51 located furthest away from the platform 30, the seat piece 10 is folded. The seat member 10 can be fixed step by step within the range of the arc-shaped arrows at both ends shown in FIG. 2 . For example, when an infant is seated, it can be fixed at 20 degrees, 25 degrees, 30 degrees, 40 degrees, and 50 degrees from the bottom, and the seat member 10 cannot be rotated forward beyond 51 degrees.

Next, the headrest 60 will be described with reference to FIGS. 3 to 5 . FIG. 3 is a perspective view of the front side of the headrest 60 . FIG. 4 is a front view of the headrest 60 . FIG. 5 is a perspective view of the back side of the headrest 60 .

As shown in FIG. 3 , the headrest 60 is a pillow portion that is substantially curved as a whole so as to enclose the head of the infant, and a back cover 67 and a front cover 68 provide a soft pillow cushion (not shown in the figure). shown) to cover.

The surface of the headrest 60 is provided with a recessed portion 69 recessed to support the back of the infant's head, and a U-shaped bank 70 protruding forward from the side wall portion 69b of the recessed portion 69 . The concave portion 69 includes a central portion 69 a that becomes the bottom of the concave portion 69 , and a side wall portion 69 b that is bent forward from the periphery of the central portion 69 a and is connected to the slope 70 . The slope 70 is formed to be continuous with the inner wall surface of the recessed portion 69 . The slope 70 is a bank-shaped portion protruding forward from the periphery of the recessed portion 69 to the height of the ears of the infant, and is provided to prevent the head of the infant from moving laterally and downward. The recessed part 69 and the slope 70 form the head support part 71 which supports the head of an infant.

As shown in FIGS. 3 and 4 , the concave portion 69 has the side wall portion 69b connected to the slope 70, so that the head of the infant can be prevented from moving laterally and downward in the side wall portion 69b. On the other hand, since the slope 70 protrudes more forward than the side wall portion 69 b , the head of the infant can be firmly supported from the left, right and below compared with the concave portion 69 . The effect of suppressing the movement of the head (the inclination of the head to the left and the right and the movement of the head downward such that the head is detached from the headrest 60 ) is high. That is, the inclination of the head of the infant in the left-right direction and the downward movement cannot be sufficiently suppressed only by the concave portion 69 . .

As shown in FIG. 4 , the slope 70 is formed into a gentle U-shape when viewed from the front. Moreover, the head support part 71 which consists of the recessed part 69 and the slope 70 has a pair of side parts 71a corresponding to the side head of the infant, and a top part as a head and neck support part corresponding to the head and neck (neck) of the infant. 71b, the side portion 71a and the top portion 71b are continuously and integrally provided. The side portion 71a supports the head of the infant from the left-right direction, and prevents the head from tilting in the left-right direction. Since the seat member 10 of the elastic chair 1 swings in the front-rear direction, the head of the infant tends to be tilted by the swing of the seat member 10, but the side portion 71a can prevent the baby's head from tilting laterally. In particular, the side portion 71a can prevent the head of an infant whose head and neck are relatively fragile until about four months after birth from tilting to the left or right and continuing the state of tilting, so that the infant can Toddlers do not become uncomfortable.

The top part 71b is provided as a part of the head support part 71, and contacts the back side of the neck of an infant. The top portion 71b has a shape protruding from the side wall portion 69b of the concave portion 69 to support the bulge from the head of the infant to the back of the head. Therefore, the back of the baby's head is supported so as to hang on the top portion 71b, and the body of the baby can be prevented from gradually rotating in the seat member 10 due to the movement of the baby and the swing of the seat member 10, so that the buttocks rise (seat on the seat). lighten).

Since the top of the baby's head is not covered by the slope 70, the top side of the head is open, and even if the head of the baby grows, the opening prevents the head of the baby from being accommodated in the head support portion 71. Happening.

In addition, as shown in FIG. 4, in the center part 69a of the recessed part 69, a plurality of small raised concavo-convex marks 72 and holes 73 which are dove eye-shaped holes are provided, respectively, so that the back of the head of the infant is provided. support near the center. The concave-convex mark 72 supports the occipital region of the infant slightly upward, and the eyelet 73 suppresses the stuffiness of the occipital region.

As shown in FIG. 5 , the inside of the headrest 60 is curved toward the rear. That is, the pillow pad and the back cover 67 are bent so as to bulge rearward so as to correspond to the concave portion of the concave portion 69 . The above-mentioned curvature is formed in a curved shape along the shape of the upper seat cover 12a that sinks due to the weight of the infant. Thereby, since the curved shape of the inner surface of the headrest 60 is brought into contact with a wide range along the curved shape of the upper seat cover 12a that sinks due to the weight of the infant, the headrest 60 is placed on the upper seat cover 12a. Internally stable. Since the headrest 60 is stable, the elastic chair 1 can stably support the head of the infant.

The curved shape of the rear surface side of the rear cover 67 includes a curved central portion 67a and a curved side portion 67b which is curved laterally from the circumference of the curved central portion 67a and descends. The curved shape of the curved center portion 67a corresponds to the curved shape of the raised portion 18 of the upper seat cover 12a. Therefore, even when the infant is not lying down, the curved center portion 67 a of the headrest 60 is accommodated in the raised portion 18 in the cloth seat 12 and is stabilized with respect to the seat member 10 . In addition, the curved shape of the curved side portion 67b corresponds to the curved shape of the upper seat cover 12a which sinks due to the weight of the infant. Therefore, when the headrest 60 is in a state where the infant is lying down, in addition to the curved central portion 67a, the curved side portions 67b also come into contact with the lowered upper seat cover 12a (become a shape along a wide range). Stable with respect to the cloth seat 12 .

In addition, since the headrest 60 has flexibility, it can be deformed into a curved shape along the shape of the upper seat cover 12a

[Effect of the invention according to the first embodiment]

The elastic chair 1 according to the first embodiment includes a headrest 60 provided with a head support portion 71 that supports the head of the infant from the left-right direction. Although the head of the infant lying down on the cloth seat 12 is easily moved by the swinging of the cloth seat 12 , the head support portion 71 prevents the head from being skewed in the left-right direction.

The headrest 60 is curved so that the curved surface shape of the inner surface follows the curved surface shape of the raised portion 18 of the cloth seat 12 . Thereby, the headrest 60 is accommodated in the curved shape of the raised portion 18 , and the headrest 60 is stabilized with respect to the cloth seat 12 .

Moreover, the headrest 60 has the top part 71b as a head-neck support part provided so that it may swell along the back side of the head-neck of an infant. Thereby, since the head and neck of an infant is supported by the top part 71b, it can suppress that an infant rotates and raises a buttocks.

In addition, the headrest 60 can move in the up-down direction with respect to the cloth seat 12 . Thereby, the headrest 60 can be arrange|positioned at an appropriate position according to the body length of an infant.

In addition, a first belt 61 and a second belt 62 for moving the headrest 60 are attached to the headrest 60 , and the belts 61 and 62 pass through the cloth seat 12 and are directed toward the inside of the cloth seat 12 side transfer. Thereby, the position of the headrest 60 can be changed by grasping the belts 61 and 62 located on the back side of the cloth seat 12 . In addition, since the belts 61 and 62 are passed through the upper slits 19 and the lower slits 20 provided in the center portion of the cloth seat 12 in the left-right direction, the headrest 60 can be avoided inside the cloth seat 12 without realizing it. The headrest 60 is attached to the cloth seat 12 so that the center positions of the left and right are aligned.

In addition, the inside of the cloth seat 12 is provided with a plurality of marks 21 indicating the positioning of the position of the headrest 60 according to the age of the infant. Thereby, since the infant can be placed on the cloth seat 12 after adjusting the position of the headrest 60 in advance, the head of the infant can be stably supported. In addition, even if the position of the headrest 60 moves, the headrest 60 can be moved to an appropriate position depending on the mark 21 .

In addition, since the headrest 60 is attached to the inside of the cloth seat 12, it is not directly soiled due to the recoil of the infant. Thereby, the frequency of detaching the headrest 60 from the cloth seat 12 for washing is reduced, and the effort for keeping the headrest 60 clean is not spent.

According to this configuration, since the back surface of the headrest 60 is formed in a curved shape along the shape of the cloth seat 12, the curved shape of the headrest 60 is accommodated in the curved shape of the cloth seat 12, and the headrest 60 is fixed to the cloth seat 12. In addition, since the head support portion 71 of the headrest 60 supports the infant's head from left and right, the infant's head is stably supported by the headrest 60 and the infant's head is prevented from tilting to the left and right. In particular, since the head of an infant whose head and neck are relatively fragile can be suppressed from being in a state of being inclined laterally, the head and neck of the infant are not in a curved state.

Moreover, the back surface of the headrest 60 is formed in the curved shape along the shape of the cloth seat 12 which sinks by the weight of the infant lying down.

According to this configuration, not only the shape of the cloth seat 12 before the infant is put down, but also the shape of the cloth seat 12 sunk by the weight of the infant, the inner surface of the headrest 60 is formed is formed into a curved shape. Therefore, since the inner surface of the headrest 60 is accommodated in the curved shape of the cloth seat 12 in the state where the infant is put down, the contact range between the cloth seat 12 and the headrest 60 which is lowered is further increased. Therefore, the headrest 60 is further stabilized with respect to the cloth seat 12 in the state where the infant is lying down. As a result, the head of the infant is stably supported without being inclined to the left and right.

In addition, on the surface of the headrest 60, a top portion 71b serving as a head and neck support portion for supporting the head and neck of the infant is provided so as to protrude.

According to this structure, since the top part 71b is in contact with the back side of the neck of the infant, the head of the infant is restrained from moving downward while supporting the neck of the infant. Thereby, the back of the baby's head is supported so as to hang on the top portion 71b, and the body of the baby can be restrained from gradually rotating in the seat member 10 due to the movement of the baby and the swing of the seat member 10, so that the buttocks rises (as in the seat becomes shallow).

The headrest 60 can move up and down along the cloth seat 12 .

According to this structure, the position of the headrest 60 can be changed in an up-down direction so that it may correspond to the body length of an infant. Therefore, the headrest 60 can support the head of the infant at an appropriate position even if the body length of the infant increases.

Belts 61 and 62 for moving the headrest 60 up and down are attached to the headrest 60 , and the belts 61 and 62 pass through the cloth seat 12 and are transferred to the back side of the cloth seat 12 so that they can be removed from the cloth seat 12 Hold on the inside side.

According to this configuration, the upper and lower positions of the headrest 60 can be changed by grasping the belts 61 and 62 inserted into the back side of the cloth seat 12 .

On the inside of the cloth seat 12, along the belts 61 and 62, a plurality of marks 21 for indicating the position of the headrest 60 according to the age of the infant are provided.

According to this configuration, the infant can be placed on the cloth seat 12 after adjusting the position of the headrest 60 to a height corresponding to the age of the infant in advance with the marking 21 set as a positioning, and therefore, it can be stably supported Infant's head. In addition, even if the position of the headrest 60 moves, the headrest 60 can be moved to an appropriate position depending on the mark 21 .

The headrest 60 is built into the cloth seat 12 .

In addition, since the headrest 60 is attached to the inside of the cloth seat 12, it is not directly soiled due to the recoil of the infant. Therefore, the frequency of detaching the headrest 60 from the cloth seat 12 for washing is reduced, and effort for maintaining the headrest 60 clean is not required.

The embodiments of the present invention have been described above, but the above-described embodiments merely represent a part of application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above-described embodiments.
