First Claim
Patent Images
1. An inflator comprising:
- a reaction can having a plurality of exit ports around the circumference thereof;
an igniter installed on a first end of the reaction can, the igniter is in communication with an electronic control unit;
a pressure vessel for storing gas, the pressure vessel has a burst disk for blocking the stored gas from exiting a nozzle of the pressure vessel; and
an impinger having a sharp portion extending from a base, the base is connectd the second end of the reaction can, whereby the firing of the igniter causes the pressure vessel to propel into the impinger causing the burst disk to be punctured.

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.
