Seat for car, has thrust that carries out overrunning by deviating gradually from reciprocal thrust in backrest folding angular range such that backrest is in folding position to make seat base in retraction position

摘要

The seat (1) has a thrust (14) and a reciprocal thrust (15) that are placed such that the thrust is in support against the reciprocal thrust in a backrest use position to maintain a rod (10) in an angular position. The thrust remains in the support against the reciprocal thrust in a backrest folding angular range to accompany the rod in another angular position, and the thrust carries out an overrunning by deviating gradually from the reciprocal thrust in another backrest folding angular range such that the backrest is in a folding position to make a seat base in a retraction position.
