ABSTRACT:
An air bag system includes an inflator, an inflatable air bag, an air bag housing substantially surrounding the air bag, and a vent-modifying mechanism operatively connected to the housing. The housing defines a vent. The vent-modifying mechanism includes a vent blocker movable from a first position to a second position to adjust inflation fluid flow through the vent, and a retention member retaining the vent blocker in the first position. A sensing tether extending between the air bag and the retention member is operable to selectively release the retention member. An inflation fluid responsive member movable between a restricting position and an unrestricting position may also be included. The inflation fluid responsive member at least partially blocks the housing vent in the restricting position, and is movable to an unrestricting position in response to pressure of inflation fluid.
