Abstract

Gas generator of lightweight construction, especially of an impact protection system for occupants of a vehicle, wherein a housing shell and a cover are made in one piece, formed of light metal such as aluminum, and have internally located screw-threaded parts which are screwed against each other, so that they are connected to one another tightly in a press fit positive lock manner and in a compression-proof manner, and also accommodate and hold between them the igniter, the propellant, and the filter. This leads to considerably reduced production costs for series production. Despite the weight reduction achieved, the gas generator is resistant to high temperatures, and the propellant gases discharged are sufficiently cool and muffled.
