1. A gas generator for generating gas under pressure comprising:

  • means for providing a first gas including a pressure vessel containing the first gas, the first gas being an oxidizing gas;

    means operatively connected with the means for providing a first gas for providing a second gas adapted to be oxidized by the first gas, the means for providing a second gas including a pyrotechnic charge for generating the second gas when ignited;

    means for providing an oxidation zone operatively connected with the means for providing a first gas and the means for providing a second gas and including an outlet, the first gas and the second gas being adapted to undergo an oxidation reaction in the oxidation zone for generating the gas under pressure;

    means operatively connected with the means for providing the oxidation zone for directing the first gas and the second gas to the oxidation zone such that oxidation zone contains a mixture of the first gas and the second gas for the oxidation reaction thereof, the second gas being of a sufficiently elevated temperature to initiate the oxidation reaction in the oxidation zone; and

    back-up catalytic means disposed in the oxidation zone for ensuring initiation of the oxidation reaction of the mixture in the oxidation zone.
