Abstract
In a vehicle seat having a backrest portion and a head support carried on the backrest portion by a connecting member, to reduce whiplash risk by forward displacement of the head support into a more effective head-supporting position, a displacement member is movably carried on the backrest portion of the seat. The displacement member has a sliding guide arrangement on which the head support connecting member is so guided that displacement of the displacement member in the transverse direction of the seat causes displacement of the head support forwardly of the seat. The displacement member is connected for displacement thereof to a resilient, mechanically stressable drive element activatable by a vehicle-specific acceleration sensor, for release and relief of the drive element to displace the head support.
