BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat that also serves as a child seat.

0002

[Prior Art] Japanese Utility Model Application Publication No. 48-106019 discloses a vehicle seat consisting of a seat and a backrest seat provided at the rear of the seat, in which the backrest seat has a downward facing corner on its upper side. It is described that a split backrest part in the shape of a square is formed, and the split backrest part is configured to be rotatable between a position on the same plane as the backrest seat and a substantially horizontal position.

0003

In the above-mentioned known example, a downward U-shaped divided backrest portion is formed on the upper side, so it cannot be installed in a backrest seat with a headrest. Also, since the entire circumference is a frame, you cannot enter from the side, making it difficult to use. Furthermore, since the effective area of the seat back seat is significantly reduced, not only does it look unsightly, but its effectiveness as a seat back seat is also reduced. In addition, it is difficult to fix because it has a structure in which a downward U-shaped split backrest is formed on the upper side. This problem can be solved by attaching the divided backrest portion to the seat seat side rather than the backrest seat side.
