Hybrid gas generator

A hybrid gas generator comprises an elongated cylindrical outer housing, and a pressure chamber that is filled with pressurized gas and that is closed off by a membrane provided on an end face of the pressure chamber. The gas generator further comprises a pyrotechnical propellant charge that is provided for opening the membrane and is accommodated in a preferably bushing-shaped propellant charge housing. The propellant charge housing is connected to the outer housing at a location outside of the pressure chamber and a longitudinal axis of the propellant charge housing extends at a right angle to a longitudinal axis of the outer housing. The generator also has an axial outflow opening situated at one axial end of the outer housing. The outer housing has a circumferential wall with a radial insertion opening for introducing the propellant charge housing. The propellant charge housing is attached to a section of the circumferential wall diametrically opposite the insertion opening in such a way that the propellant charge housing is secured at least against a movement in the direction of the longitudinal axis of the outer housing.
