In order to fill an inflatable safety restraint device such as an air bag, a relatively small pyrotechnic charge is used to pressurize a chamber of water or other suitable liquid and force the liquid out of the chamber and through a conduit in a manner wherein it is caused to intimately mix and atomize in a high speed stream of gas resulting from the combustion of the pyrotechnic charge. The heat of the combustion gas is absorbed by the liquid which is then converted into a large volume. The vaporized liquid and combustion gas is used to inflate the air bag with an essentially non-toxic, low temperature, low particulate atmosphere. The resulting combustion gas and liquid mixture may also be used to extinguish a fire.

[ What is claimed is:] [1.] A hybrid gas generator comprising:a housing having a closed section;a displaceable partition member disposed in the closed section and arranged to partition the closed section into first and second variable volume chambers;a non-flammable liquid disposed in the first variable volume chamber;a pyrotechnic charge disposed in the second variable volume chamber, said pyrotechnic charge being selectively ignitable to produce combustion gas and pressurize the second chamber in a manner which displaces the displaceable partition member in a direction which reduces the volume of the first variable volume chamber;means defining an orifice through which the combustion gas vents from the second variable volume chamber; andpassage means for transferring liquid from the first variable volume chamber and ejecting it into the flow of gas from the second variable volume chamber at a location proximate said orifice prior to venting the combustion gas through said orifice.
