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.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 108 words
A gas bag assembly disposed in the passenger compartment of a vehicle, comprising: a. an inflatable bag connected to a diffuser; b. a conical inlet means in communication with a source of pressurized gas; c. said diffuser connected to and in communication with said inlet means at its end of greatest perimeter; d. sections of said diffuser symmetric about and adjacent said inlet means apertured for aspiration of and passage of compartment air therethrough and supply to said bag; e. said sections each covered by an impermeable flexible flap in the diffuser and under predetermined pressure conditions uncovered, said flaps biased to normally cover the associated apertured section.
