Claim:
A vehicle seat comprising: a seat body having a seat back, a pair of legs, a headrest coupled to the seat back at an upper side of the seat back via the pair of legs; a load detecting unit provided on the seat back and having a movable part that displaces in a predetermined direction upon being subjected to a load from a front of the seat back; a first interacting member mechanically coupled to one leg of the pair of legs and to the movable part of the load detecting unit, that moves the one leg of the pair of legs in conjunction with a displacement of the movable part caused upon being subjected to the load and thereby displacing the headrest toward the front; and a second interacting member mechanically coupled to the other leg of the pair of legs and to the first interacting member, that moves the other leg of the pair of legs in conjunction with a movement of the first interacting member caused upon moving the one leg of the pair of legs and thereby displacing the headrest toward the front, wherein at least one of the first and second interacting members comprises a pressure-contact member that is pressure-contacted with the legs or a coupler member that connects both legs.
