a seat cushion side frame;
a seat back frame rotatably fastened to a rear end portion of the seat cushion side frame;
a seat cushion main-frame fastened between the seat cushion side frame and the seat back frame in a tiltable manner; and
a dive link fastened by a hinge mechanism between a front end portion of the seat cushion main-frame and a front end portion of the seat cushion side frame;
wherein a stopper link rotatably mounted on the seat cushion side frame is rotated by an inertial force when a head-on collision occurs, holding the dive link in place; and
wherein the stopper link includes an elastic member integral with a lower end portion of the stopper link and configured to provide an inertial motive force to the stopper link when the head-on collision occurs.
