Patent ID: 8047606

Claim:
A headrest operating device for moving a headrest toward a head of a person seated on a vehicle seat when a backside collision occurs to a vehicle, comprising: a backside collision detecting device disposed within a seat back of the vehicle seat and configured to be able to detect occurrence of the backside collision; wherein the backside collision detecting device can produce an operational force upon detection of the occurrence of the backside collision; an operation member; a headrest including a headrest base portion and a headrest support portion, supported on the vehicle seat by support tubes; a headrest moving mechanism coupled to the operation member and configured to move the headrest support portion away from the headrest base portion and toward the head of a seated person based on the operation of the operation member; an interlocking member coupled between the backside collision detecting device and the operation member, so that the operational force of the backside collision detecting device can be transmitted to the operation member via the interlocking member; and a switching device configured to be able to switch a path of movement of the interlocking member caused by the operational force of the operation member between an inoperative path and an operative path; when no backside collision occurs, the interlocking member can move along the inoperative path; and when the backside collision occurs, the interlocking member can move along the operative path, so that the operational force of the backside collision detecting device can be transmitted to the operation member.
