[Prior art]

 In this type of automobile child restraint system, both the seat portion and the backrest portion are deeply formed in order to protect the body, especially the head, from shocks and vibrations when the infant sits down. Moreover, since it is made by integral molding, it was difficult to store it in the trunk of the car when it was removed.

In order to facilitate storage in a narrow space such as a luggage compartment, there has been a device in which the backrest can be folded over the side support of the seat. However, since it is deeply molded as described above, it was not possible to fold it too small due to the high height dimension of the seat side support. In addition, in some cases, the height of the side supports was reduced to solve this problem.

[0004]

[Problems to be solved by the device]

 However, if the height of the side support is lowered, the function of protecting the infant's body becomes insufficient, which is not preferable for safety.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and the purpose thereof is to fold it to a size that can be easily accommodated in a narrow space such as a luggage compartment. An object of the present invention is to provide a child restraint system for a vehicle that can be used and that does not impair the function of protecting the infant's body.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the technical means taken by the present invention consist of a backrest part with standing head support parts on both side edges and a seat part with standing lower body support parts on both side edges. In a child restraint system for an automobile that can fold the backrest to the upper side of the seat, the head support and the backrest can be folded so that the head support can be folded to the front side of the backrest. Is characterized in that the width dimension of the backrest portion when the head support portion is folded is connected by folding means and is smaller than the inner dimension of the seat portion.

As a means for folding the head support part, it is preferable to separate the backrest part and the head support part and connect them by using a hinge or the like, but a flexible resin plate is used instead of the hinge. Or may be connected using a through shaft. The head support should be folded in the direction of the front of the backrest so that it can be folded to a position approximately parallel to the backrest. Also, when the head support is completely folded, the width of the backrest should be smaller than the distance between the inner surfaces of the lower body support that are erected on both side edges of the seat. . When the backrest is folded, the back of the backrest should be at the same height as or lower than the top of the lower body support.

Further, as a means for fixing the head support portion and the backrest portion, a perforated plate provided at an end portion of the head support portion and a hook provided inside the side surface of the backrest portion are engaged with each other. Depending on the method, off-the-shelf magnet catches or roller catches may be used.

[0009]

[Work]

 According to the above means, the head support part is folded through the folding means to a position substantially parallel to the front side of the backrest part, and the width dimension of the backrest part at this time is the inside of the lower body support part. Since it is smaller than the distance between the sides, the backrest is integrated with the head support and fits completely inside the seat. Further, the back surface of the backrest has a height equal to or lower than the height of the lower body support portion, so that the backrest can be folded more compactly.

Further, when the head support portion is opened and used, the head support portion and the backrest portion are fixed by the fixing means, and the use state is maintained.
