Abstract

The invention relates to a gas generator for a safety arrangement, in particular for a vehicle occupant restraint system, comprising a combustion chamber (4) delimited by a combustion chamber wall (4a) and filled with propellant granule (3), and also a means arranged in the combustion chamber for holding down the propellant granule. The gas generator according to the invention is characterized in that the means for holding down the propellant granule comprises a disc-shaped holding face (1) having grid holes, wherein the holding face is pressed into the combustion chamber and is connected in a form and force-fitting manner with the combustion chamber wall, and is prestressed and presses elastically onto the propellant granule, the grid holes having a smaller diameter than the propellant granule (3).
