Abstract
One aspect according to the invention can include a headrest operating device including a backside collision detecting device that can produce an operational force upon detection of occurrence of backside collision. The operational force of the backside collision detecting device can be transmitted to an operation member via an interlocking member. A switching device can switch a path of movement of the interlocking member between an inoperative path and an operative path. When no backside collision occurs, the interlocking member can move along the inoperative path, so that the operational force of the backside collision detecting device cannot be transmitted to the operation member. 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.
