Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a child seat attached to a vehicle seat.

[0002]

[Prior Art]

 In a conventional vehicle, as shown in FIG. 8, a child seat 1 is mounted on a seat 3 by a seat belt 2 which extends under the back of the child seat 1 in the vehicle width direction and is impacted by a vehicle collision or the like. At this time, the seat belt 2 is held in that position by the pulling force of the seat belt 2. However, since the child seat 1 is attached by the seat belt 2 only below the back of the child seat 1, even if the child seat 1 is restrained in the front-rear direction, there is little sense of stability against a lateral load, and the child seat 1 It is actually difficult to adjust the height of the child seat 1 by placing a spacer below the seat because it makes the attachment of the child seat 1 unstable.

[0003]

[Problems to be solved by the device]

 The present invention is intended to provide lateral stability to a child seat mounted on the seat, and to make it possible to easily adjust the height of the child seat without impairing the sense of stability. Is.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, a child seat according to the present invention is a vehicle seat or a child seat mounted on the seat by a seat belt mounted in the vicinity of the vehicle seat. A guide having a locking portion is provided, and one side of the bracket having a substantially L-shaped section is vertically guided and locked by the above guide, and the other side of the bracket is disposed on the seat back top of the seat and the seat is provided. It is configured to engage with a stem inserted into the headrest guide of the.

[0005]

[Action]

 Therefore, the child seat mounted on the seat is restrained from being displaced in the front-rear direction by the seat or a seat belt mounted in the vicinity of the child seat, and at the same time, a bracket which one side engages with a vertically extending guide on the back of the seat back. The other side engages with the stay that is inserted into the headrest guide of the seat to prevent lateral displacement, and a spacer etc. is placed below the child seat to adjust the height of the child seat or Even when the back is reclined, one side of the bracket is guided by a guide extending vertically on the back of the seat back, and the engagement between the guide and the bracket is retained, which impairs the stability of the child seat installation. The child seat on the seat. It is stably attached to the.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described. 1 to 3, a guide 13 is formed on the back surface of the seat back 11 of the child seat 10 by a pair of projections 12 having a hook-shaped cross section that extends upward and downward, and one side 15 of the bracket 14 having a substantially L-shaped cross section is formed by the guide 13. The other side 16 of the bracket 14 is hooked on the top of the seat back 21 of the vehicle seat 20 while being fitted in the upper and lower portions of the bracket 14 and is guided by the stay 23 of the headrest 22 or a bar-shaped bifurcated stay (not shown) separately prepared. Passes through the through hole 17 on the other side 16 of the bracket and is inserted into the headrest guide 24 embedded in the top of the seat back 21, so that the child seat 10 is fixed on the seat 20. On the other hand, as in the conventional case, the child seat 10 is attached to the seat 20 by a seat belt (not shown) which is inserted in the vehicle width direction below the back of the child seat 10.

Therefore, when the child seat 10 on the seat 20 is restrained in the front-rear direction by the pulling force of the seat belt when the vehicle is impacted by a collision of the vehicle, the other side 16 of the head rest stay 23 is Since one side 15 of the engaged bracket 14 is locked to the guide 13 on the back of the seatback 11, the lateral displacement of the child seat 10 is reliably prevented, so that the child seat 10 on the seat 20 is prevented. The attachment is extremely strong and stable, and it is possible to easily protect the infant sitting on the child seat 10 completely.

Also, as shown in FIG. 4, even if a spacer 30 is provided below the child seat 10 and the height of the child seat 10 is adjusted, the guide 13 on the back surface of the seat back 11 has one side 15 of the bracket 14. Since the displacement of the child seat 10 in the lateral direction is restrained by being displaced upward along the direction of the child seat 10 and the lateral displacement of the child seat 10 is restrained, the stability of attachment of the child seat 10 is not impaired.

Further, as shown in FIG. 5, when the seat back 21 is reclined rearward, the guide 13 on the back surface of the seat back 11 is displaced downward along one side 15 of the bracket 14 and the both are locked as described above. Since the child seat 10 is mounted on the seat 20 with the seat back 11 tilted rearward along the seat back 21 with the child seat 10 held, the child seat 10 can be installed stably even when the child seat 10 is used as a basket type. There is no loss of sex.

Although the guide 13 in the above embodiment is formed by a pair of protrusions 12 having a hook-shaped cross section, the guide 13 is formed by a closed cross section that extends in the vertical direction so that one side 15 of the bracket 14 can be fitted. It goes without saying that it is okay.

Next, as shown in FIG. 6, a bracket 40, which is a modification of the bracket 14, has one side 41 engaged with the guide 13 on the rear surface of the seat back 11 and the other side 42 engaged with the stay 23. Since the hinges 43 are foldably connected by a hinge 43, when the child seat 10 is mounted on the seat 20 as in the above-described embodiment, the spacers 44 are placed below the child seat 10 as shown in FIG. While the one side 41 is locked to the guide 13 on the back of the seat back 11, the one side 41 and the other side 42 of the bracket 40 are bent, so that the seat back 21 of the seat 20 does not recline rearward and the child seat 10 does not recline. Can be mounted with a rear tilt, so if there is not much space behind the seat 10. Even when the child seat 10 is used, it is convenient because the child seat 10 can be easily used as a basket type.

[0012]

[Effect of the device]

 In the child seat according to the present invention, displacement in the front-rear direction is restrained by the seat or a seat belt mounted in the vicinity thereof, and one side of the bracket is inserted into a guide on the back of the seat back and the other side is inserted into a headrest guide of the seat. Lateral displacement can be reliably prevented by engaging the stay with the seat, and the height of the child seat can be adjusted by placing a spacer etc. below the child seat, or the seat back of the seat can be reclined. Even if the child seat is tilted backwards due to factors such as the above, the locking between the guide on the back of the seat back and one side of the bracket is retained, so the child seat can always be stably attached on the seat, and It can easily and surely protect a sitting infant.
