Abstract

A head-rest of a vehicle seat with a deformable central supporting body which forms an impact zone for the head of a vehicle occupant and into which the kinetic energy of the head in the event of an accident is admitted. On both sides of the impact zone the central supporting bodies are joined by lateral supporting surfaces which are extendable out of the plane of the head-rest in the direction of travel in order to laterally support the head. In order to avoid or at least to reduce the risk of a cervical-spine whiplash injury, it is proposed according to the invention that the head-rest comprises a device for absorbing the energy admitted into the central supporting body and for outputting the absorbed energy in order to activate lateral supporting surfaces.
