ABSTRACT:
Apparatus for preventing whiplash-related injuries to a passenger in a vehicle. The apparatus includes a frame supported on a seat of the vehicle and located behind the cranium and cervical spine of a passenger on the seat. A layer of resilient material is supported on the frame, and defines a supporting means located behind the cranium and cervical spine of the passenger which defines one or more contours that interfit with the posterior contour of the passenger's cranium and cervical spine. The apparatus thereby contacts and supports the posterior portion of the passenger's cervical spine substantially simultaneously with contact and support of the passenger's cranium, thereby substantially simultaneously decelerating the cranium and cervical spine during a vehicle collision to prevent whiplash-related injuries to the passenger.
