Abstract
A gas generator for an airbag system of a vehicle comprises a combustion chamber to accommodate a propellant which is able to be activated. The combustion chamber has outflow openings for a gas which is generated after the propellant has been activated. The outflow openings are covered inside the combustion chamber by a filtering device. The filtering device is arranged spaced apart from the outflow openings. The filtering device divides the combustion chamber in axial or radial direction into a combustion space for the propellant or into one or more expansion chambers for the gas which is generated. The filtering process of the filtering device becomes more reproducible in the region of the outflow openings and is therefore improved. There is a better utilization of the filtering material and a greater lifespan of the filtering device is likewise achieved.
