ABSTRACT:
For rapid inflation of a gas bag a pressurized gas container has an outlet opening closed by a closure disc adapted to be blown off to free the outlet opening. An intermediate housing has an interior space which is divided by the closure disc into a pressure chamber provided with inlet openings for gaseous combustion products of a propellant charge and an outflow space having outlet openings for a gas mixture for filling the gas bag. A pair of propellant charges are separated from each other in a housing surrounding the intermediate housing. An accommodation space for the first propellant charge is directly connected with the pressure chamber through an open conduit. A conduit for communication of an accommodation space for the second propellant charge with the pressure chamber is closed by a closure element. The closure element is maintained in a closure position blocking the conduit at least during ignition of said first propellant charge, and is movable into an opening position by pressure arising on ignition of the second propellant charge to free the conduit.
