  • a gas-emitting substance chamber having an opening;

    a gas-emitting substance provided in said gas-emitting substance chamber comprising between about seventy-six to about eighty percent by weight of a high energy explosive and about twelve to about fifteen percent by weight of a combustible binder;

    an igniter provided within said gas-emitting substance chamber for igniting said gas-emitting substance;

    a pressure reducing valve arranged in said opening of said gas-emitting substance chamber for maintaining a desired pressure in said gas-emitting substance chamber during burning of said gas-emitting substance;

    a gas container having an opening;

    a gas provided in said gas container for oxidizing gas produced by said burning of said gas-emitting substance;

    a closure for closing said opening in said gas container;

    a mixing chamber joined to each of said gas-emitting substance chamber and said gas container in the vicinity of said opening of said gas-emitting substance chamber and in the vicinity of said opening of said gas container, said openings of said gas-emitting substance chamber and said gas container being directed toward an interior of said mixing chamber, burning of said gas-emitting substance releases gas into said mixing chamber thereby causing a gas pressure to increase in said mixing chamber which causes said closure to open, said mixing chamber including at least one outlet for directing gas resulting from said burning of said gas-emitting substance and opening of said gas container toward an airbag; and

    an airbag interconnected with said mixing chamber and inflated by said gas resulting from said burning of said gas-emitting substance and opening of the gas container.
