Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat having a support leg, and more particularly to a child seat in which a child seat and a support leg are integrally formed.

[0002]

2. Description of the Related Art When a baby or an infant is put on a vehicle, a child seat attached to a vehicle seat is used. Some child seats are provided with support legs (support legs) for the purpose of preventing shaking or rattling at the mounting position of the child seat main body when the child seat is mounted on a vehicle seat. The support leg is attached to a lower portion of the child seat body, and when attaching the child seat body to a vehicle seat, the tip of the support leg is brought into contact with the vehicle floor surface to support the child seat body. In recent years, child seats provided with support legs have been increasing in order to enhance safety of the child seat. In particular, it is expected that the number of child seats equipped with support legs will increase more and more because of the stricter criteria for child seat collision tests after 2003.

[0003]

However, there have been the following problems in the prior art. The support leg has a shape that protrudes forward from the child seat body and extends downward. Therefore, when packing is performed with the support legs attached to the child seat for shipping or storage, the storage space becomes much larger than that of a child seat without the support legs, and the complexity of packing increases. .

For this reason, a child seat has been proposed in which the support legs are separated from the child seat body, and the child seat body and the support legs are separated and stored. However, the assembling work of attaching the support legs to the child seat body is complicated, and when attaching the child seat body to the vehicle seat, there is a possibility that the support legs may be forgotten to be assembled.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, to make the storage space for a child seat having support legs as compact as a child seat having no support legs, and to provide a child seat for a vehicle seat. An object of the present invention is to provide a child seat that can prevent forgetting to assemble a support leg when attaching a child seat.

[0006]

In order to achieve the above object, a child seat according to the present invention has a child seat detachably fixed to a vehicle seat, the child seat being attached to a lower portion of a child seat main body, and a tip end of the child seat surface. And a support leg that is rotatable between a seat support position that contacts the vehicle and a storage position where the leading end is separated from the vehicle floor surface. With the above configuration, when storing the child seat,
By rotating the tip of the support leg to a storage position separated from the vehicle floor, the support leg can be moved substantially along the surface of the child seat body. For this reason, the storage space for the child seat can be made comparable to that of a child seat having no support legs, and the storage space can be greatly reduced as compared with a child seat having conventional support legs. Further, since the support legs are provided integrally with the child seat body, it is possible to prevent the user from forgetting to assemble the support legs when attaching the child seat to the vehicle body. The child seat may be provided with a fixed holding mechanism for fixedly holding the support leg moved to the storage position. In this case, since the support legs can be prevented from rotating from the storage position, the reliability of the packing operation can be increased. Further, the child seat may be configured to be prevented from being attached to a vehicle seat by the support leg moved to the storage position. With this configuration, since the child seat cannot be attached to the vehicle seat while the support legs are stored, it is possible to more reliably prevent forgetting to assemble the support legs. Further, it is preferable that the pivot of the support leg is variable. By doing so, the storage position can be adjusted at an optimum position, and the storage space can be made more compact. In addition, the rotation fulcrum of the support leg can be adjusted according to the depth of the vehicle seat. It is preferable to provide a height adjusting mechanism on the support leg. In this way, by lowering the height position during storage, the storage space can be made more compact, and the height of the support legs can be adjusted according to the height of the floor when attaching the child seat to the vehicle seat. Can be adjusted arbitrarily. In the case where there is a pair of support legs, the rotation operation can be facilitated by integrally connecting the respective support legs so as to be rotatable.

In the above configuration, the support leg may be rotatable in the front-rear direction of the child seat body, and the storage position may be on the rear side of the child seat body. With the above configuration, when a pair of support legs is used, the respective rotation fulcrums are connected to each other to form an integral body, and the connection portion is used as a rotation center, so that the pair of legs is once used. Can be rotated. In addition, the support legs moved to the rear side of the child seat main body at least partially cross the through holes of the seat belt for fixing to the seat, so that it is possible to reliably prevent forgetting to remove the support legs. it can.

In the above configuration, the support leg may be rotatable in the left-right direction of the child seat main body, and the storage position may be a front side of the child seat main body. According to the above configuration, since the child seat cannot be used unless the supporting leg moved to the storage position is rotated to the lower side of the child seat body, the supporting leg can be reliably used.
Further, when the child seat body is formed to be rotatable, rotation of the child seat body can be prevented by the support legs held at the storage position. Further, when the child seat body is attached to the vehicle seat in the opposite direction (for example, when an infant is placed), the support leg moved to the storage position abuts on the backrest portion of the vehicle seat to serve as a hook bar. . For this reason, rebound of the child seat can be prevented. In addition, the support legs may be configured to be moved independently, and each support leg is connected by a rod and a gear mechanism,
The rotation operation can be linked.
