ABSTRACT:
An inflator is formed of a cylindrical casing filled with propellant, booster filled in a tube, and auto ignition material situated inside the tube. An electrical ingitor is disposed in the casing. First gas outlet holes are disposed on the front surface of the casing and second gas outlet holes are disposed on the rear surface of the casing. The first gas outlet holes are covered by a first film member and the second gas outlet holes are covered by a second film member. As the booster is ignited by the electrical ignitor, a gas pressure of 20.about.25 MPa is applied to break only the first film member. In fire, a gas pressure of 30.about.35 MPa is applied to break both of the first and second film members.
