Abstract

Gas generator system of lightweight design, especially of an impact protection system for occupants of vehicles, containing a central area with an igniter for a combustion chamber enclosing the igniter for solid propellant, which combustion chamber in turn is enclosed by a filter chamber with discharge openings for inflating a downstream receiver, containing, in combination: a housing, consisting of an upper part and a lower part, which are screwed together, and which accommodate and hold between them the igniter, the propellant, and the filter, so that they are sealed tightly and in a pressure-proof manner from the outside, and that one of the two housing parts that can be connected to one another has an approximately mushroom-shaped cross section, as well as special filter designs and brackets for holding same during screwing together, and the selected ducting for the flow of the gas generated.
