An airbag device including a gas-emitting substance chamber having an opening. A gas-emitting substance is provided in the gas-emitting substance chamber including 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 the gas-emitting substance chamber ignites the gas-emitting substance. A pressure reducing valve arranged in the opening of the gas-emitting substance chamber maintains a desired pressure in the gas-emitting substance chamber during burning of the gas-emitting substance. A gas container having an opening contains a gas for oxidizing gas produced by burning of the gas-emitting substance. A closure closes the opening in the gas container. A mixing chamber is joined to the gas-emitting substance chamber and the gas container in the vicinity of the opening of the gas-emitting substance chamber and in the vicinity of the opening of the gas container. The openings of the gas-emitting substance chamber and the gas container are directed toward an interior of the mixing chamber. The mixing chamber includes at least one outlet for directing gas resulting from the burning of the gas-emitting substance toward an airbag. An airbag is interconnected with the mixing chamber and is inflated by the gas resulting from the burning of the gas-emitting substance.
