Abstract: A gas generator for inflating a gas bag of a vehicle occupant restraint system is provided. The gas generator includes an igniting means for producing gas and/or heat upon activation by a control signal of the vehicle. The gas generator also includes a first chamber comprising a propellant ignitable by gas and/or heat produced by the igniting means, and a second chamber comprising pressurized inflation gas. An outlet opening through which the inflation gas can flow out of the second chamber and into the gas bag is provided. The gas generator also includes a sealing means sealing the outlet opening. The gas generator is configured in such a way that after activation of the igniting means gas and/or heat produced by the igniting means ignites the propellant and a pressure wave is created under the direct or indirect impact of gas produced by the igniting means.
