Abstract

A gas generator is provided with a housing which is open at two opposing end faces and a housing wall in which several gas orifices are arranged. The housing is formed as an extruded hollow profile of aluminum or an aluminum alloy. A combustion chamber is accommodated in the housing, in which combustion chamber gas-generating material which is ignitable by means of an ignition unit is accommodated. The combustion gases arising with the ignition of the gas-generating material are cleaned within the housing by filter elements and discharged by means of the gas orifices. The filter elements are supported by holding sections integral with the extruded hollow profile and are inserted by means of one of the open end faces of the extruded hollow profile. In the installed state the filter elements extend in a straight line between the holding sections associated therewith.
