The invention concerns 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 invention also concerns a passenger restraint system for vehicles and a method of inflating and deploying the impact cushion of a passenger restraint system of this type. In accordance with the invention, the required amount of inflating gas is generated exclusively with a propellant that is in the liquid state, when the gas generator is in a state of operational readiness, and 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 liquid propellant, especially water, which is contained in a closed pressure chamber.
