Abstract: An apparatus includes a vehicle seat (10) having a tubular seat frame (60) defining a fluid manifold (66). 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 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). The actuatable device (150) is in fluid communication with the fluid manifold (66).

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).
