<p>A solid propellant gas generator (10) incorporates staged gas cooling and filtration so as to generate cool, clean gasses having a composition suitable for use in an automobile airbag inflator. A multistage filter of the gas generator (10) includes a first filtration stage comprising ceramic foam balls (30), a second filtration stage comprising a wire mesh metallic filter (32), a third filtration stage comprising a wire mesh metallic filter (34), and a fourth filtration stage comprising a ceramic filter (36). The ceramic foam balls (30) are used as a primary heat sink within the filter thereby increasing the dimensional stability of the gas generator (10).</p> |
