Abstract
An automobile seat includes a swinging motion restraint mechanism for restraining a swinging motion of a sub-frame relative to side frames. The swinging motion restraint mechanism includes a swing axis mounted on the sub-frame, a swinging motion restraint member rotatably mounted on one of the side frames and having a first contact portion and a second contact portion, both of which are brought into contact with the swing axis one at a time, and an elastic member for biasing the swinging motion restraint member toward the swing axis. In an initial state in which no load is applied to a seat back, the first contact portion of the swinging motion restraint member is held in contact with the swing axis, while when a load greater than a predetermined value is inputted to the seat back in a rearward direction, the sub-frame is caused to swing about a hinge to thereby move a headrest forward, and the second contact portion of the swinging motion restraint member is brought into contact with the swing axis, thereby holding the headrest at a position after the movement.
