Abstract

A gas generator (10) comprises an outer housing, which has at (east two housing parts (12), which are connected to each other, in the form of a diffuser bowl (14) with outflow openings (16) towards the outside and a cover (20) directly connected to the diffuser bowl (14). Inside the gas generator (10), at least one first and one second combustion chamber (30, 36) are provided, wherein the first combustion chamber (30) is delimited by an inner wall (32) and the second combustion chamber (36) is located within the space delimited by the diffuser bowl (14) and the cover (20). The diffuser bowl (14) and/or the cover (20) comprise a section (24) that is shaped, in particular deep-drawn, into an indentation, forming at least partially a circumferential section of the inner wall (32).
