Abstract
A vehicle seat of the invention has an upper movable member (10) supporting a headrest (3), a lower movable member (30) provided inside a backrest, and a coupling mechanism for coupling the upper movable member and the lower movable member. The coupling mechanism includes an upper link mechanism (15) positioned in an upper part of a side frame (40) and coupled to the upper movable member, a lower link mechanism (32) positioned in a lower part of the side frame and coupled to the lower movable member, and a rod (27) extending along the side frame and coupling the upper link mechanism and the lower link mechanism. The upper link mechanism amplifies a backward moving amount of the lower movable member, and moves the headrest forward.
