A hybrid air bag system has a simple internal structure and can be manufactured at a low cost. The hybrid inflator is positioned within a first container (210) which has a rupturable cover and a bottom plate. The hybrid inflator has a second container (214) defining a first chamber (302) filled with a quantity of compressed gas, and then sealed. A pyrotechnic heater (350) contains a pyrotechnic charge (366) and squib (364) therein and generates high temperature combustion products by burning a pyrotechnic charge contained within a second chamber, a booster charge (384), and a gas generating material (386) contained within a third chamber. The combustion products push upwardly against a lower end surface of an operation pin (420) elastically supported by a plate spring (412) and slidably and vertically positioned within a fourth chamber (410). The operation pin ruptures a burst disk (330) sealing the first chamber. Consequently, the compressed gas in the second container (214) and the combustion products are united and injected into an inflatable air bag to inflate the air bag. Thus, a passenger in a motor vehicle can be protected from colliding with a structural part of the motor vehicle.
