Headrest for vehicle seat

A headrest in combination with a seat of a vehicle having a seat cushion and a seat back foldable downwardly, wherein said vehicle has a floor, wherein said seat cushion has a forward end portion facing forwardly of the vehicle, said forward end portion being rotatably connected with said floor so as to allow the seat cushion to be flipped over relative to said forward end portion to an upright non-use position, wherein said seatback is rotatably connected to said floor at the lower end portion thereof opposite to said top thereof, thereby allowing the seat back the be folded downwardly about said lower end portion to a horizontal non-use position, and wherein said seat back has a forward surface facing forwardly of said seat;

• the headrest comprising:
• a headrest body of a generally inverted L shape in section, which has a generally horizontal top portion and a generally vertical support portion extending vertically from said generally horizontal top portion, wherein said generally horizontal top portion is rotatably engaged to an at least one headrest stay element so that said generally vertical support portion is swingable relative to said headrest stay element in a forward direction and a backward direction of said seat;
• said headrest stay element being slidably inserted through a top of said seat back, thereby allowing said headrest body to be vertically movable toward and away from the seat back;
• and
• a wire provided between said seat cushion and said at last one headrest stay element, such that one end thereof is connected with the seat cushion and another end thereof is connected with the at least one headrest stay element;
• with such an arrangement that, upon said seat cushion being flipped over to said upright non-use position, said wire is drawn in a direction to said seat cushion, which in turn causes said headrest stay element as well as said headrest body to move downwardly to said seat back, so that said generally horizontal top portion of said headrest body is contacted on said top of said seat back, while said generally vertical support portion of said headrest body is contacted on and along the upper region of said forward surface of said seat back, thereby allowing said seat back to be folded downwardly to said horizontal non-use position without contact of said headrest body with said seat cushion.
