Abstract
The compressed gas inflator has a movable pressure vessel. The pressure vessel is biased away from an impinger by a spring. At the occurrence of a car crash, the igniter in the compressed gas inflator is fired. The burning of the pyrotechnic material in the igniter produces sufficient output energy to overcome the biasing force of the spring and propel the pressure vessel into the impinger. The impinger ruptures a hole in the burst disk of the pressure vessel and the gas in the pressure vessel is able to quickly exit the pressure vessel.
