Abstract
A gas generator (10) utilizes at least three segregated propellant container/combustion chambers (22, 32 and 34), each having a plurality of nonazide propellant grains (20, 36 and 38) therein, and an igniter (16) for igniting only the propellant grains (20) located within the first combustion chamber (22). The nonazide propellant produces enough heat energy to subsequently ignite the segregated propellant grains (36 and 38) by forced convection and/or heat conduction. The output inflation profile can be tailored to optimally cover a range of 10 to 90 percentile vehicle occupants.
