Abstract
A gas generator for air bags having a container holding a combustible gas mixture and fitted with a closure which opens into a combustion chamber fitted with a gas outlet in which the gas mixture is ignited by an ignition device. To provide a fast-reacting ignition device and generate a controllable flow of pressurized gas at a relatively low temperature, the container is mainly filled with a pressurized inert gas and contains 0.1 to 2.0% vol. of a hydrocarbon and 0.5 to 10% vol. of a gaseous oxidizing agent. On being actuated, the ignition device opens the container closure, ignites the gas mixture flowing into the combustion chamber and maintains combustion by the continuous supply of energy.
