A housing for a gas generator for inflating a safety bag in a passenger vehicle is constructed of modular units preferably having a tubular or cylindrical tubular configuration. At least one combustion chamber and one filter casing are joined to each other so that the longitudinal axes of the units align with each other longitudinally. An axially facing gas exit from the combustion chamber into the filter casing provides an initially axial gas flow which is then diverted radially outwardly from the filter casing into the safety bag.

A housing for a gas generator for inflating a safety bag in a passenger vehicle, comprising at least three, cup-shaped tubular enclosure components having substantially the same cross-sections and including two first cup-shaped components each having a tubular jacket and one closure end wall integral with said tubular jacket for forming together a combustion chamber having a longitudinal central axis, gas exit means in at least one of said closure end walls facing axially, and at least one second cup-shaped component forming a filter casing also having a longitudinal axis coinciding with said central axis of said combustion chamber, first means for securing said two first cup-shaped components to each other to form said combustion chamber with a tight seal, further means for securing said second cup-shaped component forming said filter casing to said one end of said combustion chamber where said gas exit means are located to form said housing, so that generated gas can enter into said filter casing in an axial direction through said gas exit means, and gas discharge openings in a peripheral wall of said filter casing for discharging gas into said safety bag substantially in a radial direction of said filter casing, said at least three cup-shaped components forming a modular tubular construction in which the volume of said combustion chamber can be changed by providing one of said first two cup-shaped components as units having different lengths.
