Abstract
Abstract An overhead energy attenuating panel in a vehicle moves from an inactive position above the occupants, on the inside of the roof of the vehicle, to a position in front of the front seat passengers upon a generally headon crash, and a mound of soft material formed by the overhead protector receives and protects a person projected against it on such a crash. In one form of the invention, the mound of soft material is an air bag which inflates as the overhead panel moves between the passengers and the vehicle windshield.
