ABSTRACT:
An airbag restrain system is disclosed for use in automotive protective systems. The airbag restraint system includes an inflatable airbag cushion having a tether coupled to the interior surface of the cushion. The airbag restraint system further includes first and second inflators for dual mode airbag cushion deployment. Upon a pre-impact condition, the first inflator deploys to partially inflate the cushion and release the tether. The second inflator also deploys to inflate the cushion to approximately full capacity. Upon an impact condition, only the second inflator deploys and the tether extends until taut to limit expansion of the cushion. Means are provided to retain and release the tether in response to the first inflator.
