ABSTRACT:
An airbag module (10) employing a deflagration venting system (40) for adaptively changing the level of venting provided during airbag inflation is disclosed. The adaptively controlled airbag system (10) includes an airbag (12) in fluid communication with an airbag inflator (18). A manifold (16) is provided for directing the output of the airbag inflator (18) into the airbag (12), and a reaction canister (22) houses the airbag (12), the airbag inflator (18), and the manifold (16). A deflagration device (40) is provided for selectively venting the airbag module (10). The deflagration device (40) may be activated for creating at least one variable shaped vent (50, 52) for regulating output from the airbag inflator (18) and adaptively changing the deployment force of the airbag (12).
