Seat
First Claim
1. A seat having a height adjusting mechanism for adjusting height of a seat cushion with respect to a floor, and comprising a support link for supporting said seat cushion by attaching a lower portion to the floor side and attaching an upper portion to the seat cushion side, and adjusting the height of said seat cushion by a tilting movement in the forward and backward directions within a perpendicular face;
- a stopper link in which a base end portion is attached to said floor side so as to rotate a rotating end portion in the forward and backward directions within the perpendicular face, and a projection projected on the side is arranged on said rotating end portion side;
an irregular face arranged on said support link side so as to be extended in a direction crossing a moving locus of said projection, and inhibiting further rotation of said support link in cooperation with said projection when the irregular face is engaged with said projection by receiving a colliding load of a supposing direction;
a stopper abutting on said projection in a position of said projection not engaged with said irregular face, and inhibiting that said projection is separated from said irregular face any more; and
biasing means for biasing said stopper link in a direction in which said projection abuts on said stopper.

Abstract
The present invention provides a seat having a colliding stopper 51 operated for a short time at a time of collision.
The seat is constructed by a support link 23 for supporting a seat cushion by attaching its lower portion to the side of a floor and attaching its upper portion to the seat cushion side, and adjusting the height of the seat cushion by a tilting movement in the forward and backward directions within a perpendicular face; a stopper link 55 in which a base end portion is attached to the floor side so as to rotate a rotating end portion in the forward and backward directions within the perpendicular face, and a projection (57) projected on the side is arranged on the rotating end portion side; an irregular face 61 arranged on the support link 23 side so as to be extended in a direction crossing a moving locus of the projection, and inhibiting further rotation of the support link 23 in cooperation with the projection when the irregular face is engaged with the projection by receiving a colliding load of a supposing direction; a stopper (65) abutting on the projection in a position of the projection not engaged with the irregular face 61, and inhibiting that the projection is separated from the irregular face 61 any more; and biasing means (67) for biasing the stopper link 55 in a direction in which the projection abuts on the stopper.
