Date Aug. 29, 1996A gas generator of sheet-metal constructional type for a motor vehicle passenger protection device, the generator having a concentric style of construction with a combustion chamber (2) with a gas-generating charge (3) being disposed around an ignition chamber having an igniter and an ignition charge (1) and the combustion chamber (2) being surrounded by an expansion chamber (4). To achieve lower manufacturing costs, a smaller overall size combined with less weight and good recycling properties, the sheet metal parts forming the combustion chamber (2) and the expansion chamber (4) are connected to one another exclusively by metal-forming techniques.
