Abstract
Abstract A gas bag assembly for vehicle occupant constraint upon impact of the vehicle. The gas bag assembly comprises an occupant protecting inflatable bag. The bag is partially filled with gas supplied by a gas source, such as stored gas or a gas generator, or a combination of the two, through a cone. The cone supplies gas to a diffuser which is in communication with the interior of the vehicle. Upon passage of inflating gas through the cone for inflation of the outer bag, the diffuser is supplied, because of pressure differential by the action of the cone on the gas from the source, with air from the interior of the vehicle by aspiration.
