BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laterally recoil type seat.

[0002]

2. Description of the Related Art A rear seat (a second seat or a third seat) of an automobile is provided with a seat back tilted to a rear side in order to enlarge a luggage compartment behind the rear seat, and then the entire rear seat is provided with a seat cushion. There is a horizontal recoil type structure in which it is rotated so as to stand up around the outer end (as a similar technique, Japanese Utility Model Application Laid-Open No. 61-1283).
No. 7).

[0003] In this type of rear seat, a tag belt provided on a lower surface of a seat cushion is removed and locked to a vehicle body (such as an assist grip) after the side seat is in a side recoil state. It can be held.

[0004] The tag belt includes a base portion fixed to the lower surface of the seat cushion, a hook portion locked to the vehicle body, and a belt portion connecting the base portion and the hook portion. The hook portion is attached with a hook that is pressed against the base portion so that the hook portion can be easily removed during use.

However, in such a conventional technique, the hook portion is engaged with the base portion in a push-fit state by the hook, so that the foot of the occupant cannot be engaged with the hook portion. When they hit the belt portion, they rotate, resulting in deterioration of appearance.

[0006] The direction in which the hook portion is pressed onto the base portion corresponds to the direction in which the seat cushion is flipped up, and the direction in which the hook portion is removed from the base portion corresponds to the direction in which the seat cushion is returned to its original seated state. Therefore, when the seat cushion is quickly returned from the flipped-up state to the original sitting state, the hook portion may be detached from the base portion.

The present invention has been made by paying attention to such a conventional technique. When the hook portion does not rotate and the seat cushion is returned from the flipped up state to the original sitting state, the hook portion is moved to the base portion. It is intended to provide a side recoil type seat that does not come off.
