Abstract
A gas generator for deploying and inflating an impact cushion of a passenger restraint system, with a gas generator housing, which has at least one seal, for holding a propellant for generating the required quantity of inflating gas for the impact cushion. The required amount of inflating gas is generated exclusively with water that vaporizes virtually instantaneously, when an emergency occurs, i.e., when the restraint system is activated. When the restraint system is activated, the required vaporization is brought about by depressurization of the heated water, which is contained in a closed pressure chamber.
