Filter medium and use thereof in an air bag filter

摘要

A filter medium comprises metal particulates including at least about 10 % non-linear metal fibers. The metal particulates are sinter bonded to one another and the filter has a voids volume of at least about 35 %. The filter medium may be used in an air bag inflator (14) which includes an inflator housing (22) cooperatively arranged with an air bag to direct gas from the housing (22) into the air bag. A combustible material (24) and an ignitor (26) are disposed within the inflator housing (22). An air bag filter (28) is positioned in the gas flow path between the ports (20) and the combustible material (24) to filter and/or cool the gases before they are propelled into the air bag.
