Abstract:
A system for venting an air bag module comprising:a single-piece air bag cushion retainer ring having an opening; an air bag cushion secured to the air bag cushion retainer ring; an inflator for generating gas to inflate the air bag cushion; at least one spring positioned and compressed between the inflator and the air bag cushion retainer ring such that the spring biases the inflator and the air bag cushion retainer ring away from each other, wherein the inflator is urged away from the air bag cushion retainer ring; a quick-release device securing the air bag cushion retainer ring to the inflator and maintaining the spring in a compressed position; sensors to sense occupant and crash information; and a restraint control module electrically connected to the quick-release device, the restraint control module capable of receiving information from the sensors and computing if venting is required; wherein if venting is required, the restraint control module signals the quick-release device to release the air bag cushion retainer ring from the inflator to allow the spring to urge the inflator away from the air bag cushion retainer ring to create a passageway between the retainer ring and the inflator to allow venting of the gas from inside the air bag cushion.
