A vehicle seat has a back-rest ( 1 ) carrying a head-rest ( 2 ). A mechanism is provided to move the head-rest ( 2 ) forwardly relative to the back-rest ( 1 ) in response to a rear impact situation. An element ( 9 ) is operatively located between the head-rest ( 2 ) and the mechanism ( 6 ) which is adapted to yield when exposed to a force in excess of a predetermined force. Thus the force that can be applied by the head-rest ( 2 ) to a head ( 8 ) of an occupant of the seat, is limited to be a maximum of 200 Newtons, with the preferred value being 100 Newtons.
