1. A gas generator for a safety arrangement, in particular for a vehicle occupant restraint system, comprising:

  • a combustion chamber delimited by a combustion chamber wall;

    longitudinal ribs formed in the combustion chamber wall and arranged so as to oppose each other;

    propellant granule filled into the combustion chamber to a preselected filling level; and

    a means arranged in the combustion chamber for holding down the propellant granule, wherein the means for holding down the propellant granule consists of a perforated metal sheet having two opposed straight edges, wherein the perforated metal sheet is pressed into the combustion chamber so that the straight edges engage the longitudinal ribs, thereby forming a form- and force-fitting connection, wherein the perforated metal sheet is pre-stressed for pressing elastically onto the propellant granule, thereby arresting the propellant granule at the preselected filling level, and wherein the holding face has grid holes having a diameter smaller than the propellant granule.
