ABSTRACT:
The vehicle seat has a seat back that is extended upwards by a headrest. The headrest is supported by at least one rigid stalk that is vertically slidable in a socket secured to the seat back, with a certain amount of clearance for forward pivoting. The stalk is urged angularly rearwards by a spring towards a rest position in which notches formed in the rear face of the stalk co-operate with a stop member secured to the socket. Starting from this rest position, the headrest can be moved angularly forwards by a user into an adjustment position where the stalk is free to slide vertically in the socket.
