跳ね上げ椅子の緩衝装置

Shock absorber of tip-up seat

Abstract

PROBLEM TO BE SOLVED: To provide a shock absorber of a tip-up seat such that a cushioning material for a colliding part can easily be mounted and that the seater is stably supported. SOLUTION: A mounting groove 45 which opens toward a stopper 27 is formed in a colliding part (44a), 44b which, when a seat is folded down to a horizontal position, collides against the stopper 27 to regulate rotation, and a cushioning material 43 is mounted in the mounting groove 45; a part of the cushioning material 43 is projected outwards from the opening of the mounting groove 45, and at the collision of the stopper 27 the stopper is first received by this projecting part. When someone is seated, the entire cushioning material 43 is pressed into the mounting groove 45 by the weight of the body of the seater to force the stopper 27 to directly collide against the colliding part (44a), 44b, thus avoiding sinking of the seat, and supporting the seater stably.
