Gas generator of essentially cylindrical or tubular construction containing a solid propellant or solid fuel for ignition in a combustion chamber by an electricallyactivatable igniter, with filter media for cooling and filtering the generated gas before this escapes for inflating a restraining medium such as an airbag, wherein the construction is made up of: - a combustion chamber cylinder open at one face end, having at the other face end both a central igniter with electrical contact 1 and also a peripheral holding and centering ring; - a prefabricated filter that can be pushed into the combustion chamber cylinder, in particular for prefiltering and cooling, essentially in the shape of a strip, covering the openings in a partial area of the periphery of the combustion chamber cylinder; - a second tubular prefabricated filter surrounding (concentrically) the combustion chamber cylinder, held in an outer housing made of sheet metal with gas outlets, securely held on the periphery and at the face ends to the combustion chamber cylinder between the holding and centering ring mounted on the one closed end wall and also secured on a cover with a protrusion for positive connection with the tubular filter.
