1. A vehicle seat with a backrest, a headrest and support means to adjustably mount the headrest on said backrest, said headrest being provided with a mass body coupled thereto, said mass body being located to enable a displacement of the headrest relative to the support means in case of a force acting on the mass body and said headrest being movable from an initial position for use to a position in which the headrest is displaced for a predetermined distance mainly to the front of the vehicle under the effect of forces occurring at said mass body in a rear vehicle collision, said forces being caused by the inertia of the mass body.
