When the lock lever is disengaged from the groove by manipulating the release handle in a downward motion, a dump spring allows the headrest portion to assume a folded or dumped position. In the folded or dumped position, the headrest portion fits compactly against the back portion of the seat. The manual release handle can be associated with either the left or the right side of the headrest assembly allowing the same assembly to be used on either side of a vehicle, e.g., the driver or passenger side of the vehicle, as well in the front and rear seats.

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.

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.
