Air bag system and method

摘要

An air bag system includes an inflatable air bag and a housing formed with a vent. A tether release/vent-modifying mechanism is connected to the housing and has a plurality of walls and a movable member. The movable member has a cap portion and a rod portion extending longitudinally from the underside of the cap portion. A first broad portion extends from the cap portion forward of the underside of the cap portion and covers or uncovers a vent in the housing when the movable member is actuated to move between first and second positions to release tethers connected to the air bag.
