Abstract: An inflator (14) includes a structure (50, 70, 90) that helps define a chamber (42) from which inflation fluid flows. The structure (50, 70, 90) includes an end cap (90) having a side wall (92). A closure member (104) is rupturable to release inflation fluid from the chamber (42). An initiator (230) is actuatable to rupture the closure member (104). A filter retainer (170) includes a side wall (172) that defines a cavity (176). The side wall (172) of the filter retainer (170) includes a rim portion (196) that forms a terminal end of the side wall. A filter assembly (120) is positioned in the cavity (176) of the filter retainer (170). First segments (260) of the rim portion (196) are deformed to clamp the filter assembly (120) to the filter retainer (170). Non-deformed second segments (262) of the rim portion (196) engage an inner surface (264) of the side wall (92) of the end cap (90). The second segments (262) help position the end cap (90) and the filter retainer (170) coaxially with each other.

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).

The apparatus also includes at least two deployable vehicle occupant protection devices (120, 130, 140, 142) for helping to protect a vehicle seat occupant from injury in the event of a vehicle collision. The protection devices (120, 130, 140, 142) are spaced apart from each other. 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).
