Patent ID: 7758115

Claim:
A headrest inclining apparatus which receives pressure from a passenger and inclines a headrest to a front side of a vehicle, and which comprises a headrest drive provided in an upper part of a vehicle seat back, a wire drive provided in a lower part of the seat back, and a tension transmission member connecting the headrest drive and the wire drive, wherein: the headrest drive includes a support bracket to fix the headrest, a holder to hold the support bracket to be slidable in a vertical direction, and an actuator to move the support bracket upward, a projection projecting to inside of the holder is provided in an upper part of a rear wall, with respect to the vehicle, of the holder, a cam crest corresponding to the projection is formed in the support bracket, and a coefficient of friction between the projection and cam crest is higher than a predetermined value, and when the headrest is pressed by a passenger's head, the projection locks the cam crest by frictional resistance at a position where the headrest is pressed.
