A hybrid inflator (10) for a cushion or air bag comprising: a pressure vessel means (16) for storing a volume of stored gas at an elevated pressure, including at least one opening (22) adapted to communicate gas within the pressure vessel to a cushion (84), a mixing chamber (60) defining a volume si

A hybrid inflator (10) for a cushion or air bag comprising: a pressure vessel means (16) for storing a volume of stored gas at an elevated pressure, including at least one opening (22) adapted to communicate gas within the pressure vessel to a cushion (84), a mixing chamber (60) defining a volume significantly smaller than the remaining volume of the pressure vessel; a disk (70) for providing a rupturable seal in the pressure vessel; a heat and gas generator (30,32,40,42,52,54) responsive to a control signal, for generating heated media for increasing the temperature of the stored gas at least in the mixing chamber (60), and for directing the heated media into the mixing chamber (60) and onto the disk for opening same.
