Abstract: Inflatable airbag assemblies can be mounted on a driver's side of a vehicle within a steering wheel. A gap is formed between the airbag assembly cover and the steering wheel. Maintaining a consistent width of the gap can be accomplished with an airbag assembly that is bolted to the steering wheel by minimizing the number of components used to attach the airbag assembly to the steering wheel. A flexible airbag housing mounting bracket can be used to allow the housing and cover to be positioned and oriented within the steering wheel so that the gap between the airbag cover and the steering wheel is maintained.

Abstract: A relief valve and related systems and methods have particular use in fluid distribution lines. The relief valve comprises a body defining a cavity and comprising at least first and second openings in fluid communication with the cavity. A connector piece is connected to the body at the first opening to connect the valve to a fluid distribution line. A rupture disc is disposed within and obstructs the first opening. When it is desired that fluid from the fluid distribution line be vented from the system, the rupture disc is punctured via activation of an active material initiator and thereby allows for fluid communication through the first opening of the valve.

Abstract: A post-deployment, position-stabilized curtain airbag has a top edge from which an inflatable safety cushion is supported by a vehicle for deployment into a vehicle passenger compartment between occupant and occupant enclosure. A fill chamber is secured to the top edge of the safety cushion. An inflatable structural member is mechanically connected to the safety cushion. The fill chamber directs pressurized gas into the safety cushion and the structural member. The structural member deploys into the passenger compartment between the safety cushion and occupant enclosure limiting outboard displacement of the safety cushion. The structural member fully deploys after the safety cushion. Another structural member deploys along the top edge of the safety cushion limiting pivoting of the safety cushion there relative to the fill chamber. Pressurized gas enters each structural member through auxiliary passageways having oppositely directed entrances and outlets.
