Abstract
A hybrid system is described for inflating an automobile passenger restraint bag. Part of the gas for inflating the bag is stored in a high pressure gas reservoir. Another portion is generated by combustion of a pyrotechnic mixture. In a preferred embodiment the gas storage cylinder and pyrotechnic generator are coaxial with an axial gas flow passage through the pyrotechnic generator for collecting and conveying gas. A frangible diaphragm separates the pyrotechnic gas generator from the high pressure gas storage vessel. The gas generator has four compartments surrounding the gas flow passage, each containing a pyrotechnic gas generator grain. Combustion gas flows from one of these compartments through another and thence to the axial gas passage. In each embodiment the two inflation gas sources are in series with the inflatable bag rather than in parallel with each other.
