Abstract
In a vehicle seat having a backrest portion and a head support carried on the backrest portion by a connecting device, to reduce whiplash risk by forward displacement of the head support into a more effective head-supporting position, a displacement device is linearly movably carried on the backrest portion of the seat. The displacement device has a sliding guide arrangement on which the head support connecting device is so guided that displacement of the displacement device in the transverse direction of the seat causes displacement of the head support forwardly of the seat. The displacement device is connected for displacement thereof to a pyrotechnic drive element on the backrest portion, with the drive element being activated by a vehicle-specific acceleration sensor.
