ABSTRACT:
An airbag module providing adaptive performance. The module includes a housing defining an interior. At least an inflator is received within the housing, and preferably the folded, uninflated cushion, also. Various arrangements are provided to selectively block, or create, a vent extending through the housing. This vent, when open, permits the inflation gas provided by the inflator to exit the housing without entering the cushion. The vent may be initially open, and blocked by a sliding cover block, may be initially closed and opened by movement of a slide plug, or may be initially closed and opened by deformation of a portion of the housing. The venting of the inflation gas will at least slow the rate of inflation of the cushion, and may reduce the final pressure within the cushion. As such, the housing will be vented for less severe collisions, and will not be vented for more severe collisions.
