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.
Claims11
A vehicle seat including
- a backrest portion,
- a head support,
- connecting means mounting the head support to the backrest portion,
- a displacement means movable on the backrest portion, the displacement means comprising a sliding guide means guiding the head support connecting means and operable to produce displacement of the head support forwardly in the longitudinal direction of the seat in response to displacement of the displacement means in the transverse direction of the vehicle seat, and
- a resilient mechanically stressable drive means operatively connected to the displacement means for displacement thereof, the drive means being connected to a vehicle-specific acceleration sensor means for release and relief of the drive means.
