At a vehicle rear-end collision, the locking unit 40 is released by a control unit 50 for detecting the vehicle rear-end collision. As a result, the left and right headrest members 11, 12 rotate forward about the vehicle, so that a sheet 13 stretched between respective separation ends of the members 11, 12 is unfolded to restrict a passenger's head without making use of the passenger's inertia at the collision, surely and rapidly.",
