The seatback has the other one of a guide member and follower. The guide member has a guideway and the follower engages the guideway of the guide member such that upon impact to the vehicle forward inertia of the headrest will cause the follower to engage the guideway in such a manner as to cause the headrest to move in a manner so as to support the head of an occupant irrespective of whether occupant is in contact with the seatback.
