Abstract
A structure and assembly technique for providing an internal reinforcement for an air bag module to restrain bulging of the module while minimizing the size of the module. The air bag module comprises a container with a wall defining a cavity for a gas generator and at least a part of an air bag. The wall also defines an opening through which at least part of the bag is inserted into the cavity. A reaction member, preferably a fabric tether strap, is connected with at least two points of the wall adjacent the container opening and extends across the opening in the container. The tether strap is located internally of the container and resists deformation of the container under the pressures of air bag deployment, without increasing the size of the module. The tether strap is preferably constructed as a part of the air bag itself, and is incorporated into the container at the time the air bag is assembled with the container. Moreover, the assembly process is designed to enable the bag to be folded into the container and around the tether strap, in a manner which is designed to promote effective deployment of the bag despite the incorporation of the tether strap internally relative to the container.
