Abstract
An air bag system having an air bag, an impact sensor, and a calculator, including vent holes formed at a joint of the air bag and an inflator to communicate with the air bag; and vent hole opening control means for regulating the opening of the respective vent holes. The vent hole opening control means has a rotor with a plurality of slots formed along a circumference to overlap the vent holes, and a gear extending to the outside; a stepping motor engaging with the gear of the rotor to drive the rotor by stages; bearings provided to the inflator coupling disc to support the free rotation of the rotor; and a compression ring for making the bearings contact the rotor.
