AI Technical Summary

Benefits of technology

[0012] As in the child seat, the support means is provided to support the seat cushion pulled out from the recessed portion in the back rest of the vehicle seat in the horizontal condition, the seat cushion of the child seat is supported in place without any contact with the seat cushion of the vehicle seat. Even if the seat cushion of the child seat was received by the seat cushion of the vehicle seat, the seat cushion of the child seat would be avoided from an influence caused by the cushion property of the vehicle seat. This is useful to eliminate vertical displacement of the seat cushion of the child seat caused by the cushion property of the vehicle seat and to avoid deformation and inclination of the seat cushion of the child seat caused by a difference in weight of children seated thereon. This is useful to retain a posture of the children seated on the seat cushion of the child seat in a stable condition. Even in the occurrence of a head-on collision, the seat cushion does not occur any submarine phenomenon of the child's buttocks so that the seat belt acts to securely restrain the waist portion of the child without displacement toward the belly of the child.

[0014] As in the child seat, the back rest is retained in the retracted position and retained in the forward position where the front surface of the back rest is placed to coincide with the front surface of the back rest of the vehicle seat, the depth of the recessed portion in the back rest of the vehicle seat can be adjusted in accordance with the body size of the child seated on the seat cushion of the child seat Thus, in use of the child seat, a child of small body can be entered into the recessed portion of the vehicle seat without any difficulty and seated on the seat cushion of the child seat so that the child is securely fastened by the seat belt by adjustment of the depth of the recessed portion. In use of the child seat for a child of large body, the child can be seated on the seat cushion of the child seat without any difficulty by adjustment of the depth of the recessed portion so that the child is securely fastened by the seat belt.

Problems solved by technology

Accordingly, the seat cushion of the child seat is deformed and inclined in accordance with the weight of a child seated thereon, causing the seated posture of the child unstable.

However, when the child seat is used by a child of large body, it is difficult for the child to enter his back into the recessed portion of the vehicle seat for seating on the seat cushion of the child seat.

In such an instance, the seat belt may not be securely fastened to restrain the child body.

However, the first and second problems discussed above may not be solved.
