A headrest device for supporting a headrest with respect to a seat. A lower frame is connectable to the seat, and an upper frame is provided for supporting the headrest thereon. A pair of link brackets connects the lower frame to the upper frame for pivotal motion of the upper frame with respect to the lower frame through a limited range of motion between a forward tilt limit position and a rearward tilt limit position. A motor is operatively connected one of the link brackets to move the upper frame between the forward tilt limit position and the rearward tilt limit position in response to a control signal.
