Abstract: An inflator (22) for providing inflation fluid ( ) to inflate an inflatable vehicle occupant protection device (14) includes a container (30) storing the inflation fluid under pressure. The container (30) has an outlet passage (80) through which the inflation fluid flows from the container. A rupturable closure member (92) fixed to the container (30) blocks flow of inflation fluid through the passage (80). A support (100) for the rupturable closure member (92) defines a chamber (110) adjacent the rupturable closure member (92). The rupturable closure member (92) has a first portion (122) deformed into the chamber (110) by the pressure of the inflation fluid and a second ring-shaped portion (124) encircling the first portion (122). An initiator (98) ruptures the closure member (92) when actuated by shearing the first portion (122) from the second portion (124).

Abstract: A Restorable Vehicle Occupant Safety System to replace present pyrotechnic airbag systems. The system is comprised of an air pressure storage vessel 21 that is fluidly connected to an air distribution manifold 36, electronic sensors that preclude an impending crash, valves which are sensor activated to inflate airbags for driver, passenger, knee bolster, side impact, and rollover units as well as seatbelt pre-tensioning units. The present system will safely deploy the airbags in a substantially safe increment of time before a crash condition and restore the airbags to their original position in the event the crash condition does not occur.

The protection devices (120, 130, 140, 142) are in fluid communication with the fluid manifold (66) and are deployable by fluid directed into the protection devices from the fluid manifold. A single actuatable device (150) provides pressurized fluid for deploying one or more of the protection devices (120, 130, 140, 142).

Abstract: An apparatus (10) includes a frame structure (32) defining a deployment opening (40), an inflatable vehicle occupant protection device (14) aligned with the deployment opening (40), and a deployment structure (24) extending across the deployment opening (40). The deployment structure (24) has first and second locking portions (70, 72) in releasably interlocked engagement with the frame structure (32) at locations spaced apart across the deployment opening (40). The deployment structure (24) is configured to undergo non-rupturing deflection under the influence of inflation fluid pressure forces applied by the protection device (14). Such non-rupturing deflection of the deployment structure (24) moves the first locking portion (70) partially out of interlocked engagement with the frame structure (32), and moves the second locking portion (72) fully out of interlocked engagement with the frame structure (32).

Abstract: An inflator (10) comprises a housing (20) defining first and second combustion chambers (100, 120). A first inflation fluid source (140) in the first combustion chamber (100) is actuatable to effect flow of inflation fluid. A first initiator (12) in the housing (20), when energized, effects actuation of the first inflation fluid source (140). A second inflation fluid source (150) in the second combustion chamber (120) is actuatable to effect flow of inflation fluid. A second initiator (124) in the housing (20), when energized, effects actuation of the second inflation fluid source (150). The housing (20) deforms due to the pressure of inflation fluid in the housing upon actuation of one or both of the inflation fluid sources (140, 150). The housing (20), after deforming, has a fluid passage (90) for directing flow of inflation fluid out of the housing. The flow area of the fluid passage (90) varies in accordance with the pressure of inflation fluid in the housing (20).
