An inflator for a vehicle occupant safety apparatus including an inflatable airbag has a filter which removes undesirable combustion products without detrimentally reducing the pressure of the gas flow into the inflating airbag. The filter comprises a plurality of spaced apart filter layers having offset gas flow openings to define tortuous gas flow paths through the filter.


A filter for removing material from gas generated by a gas generating material in a vehicle occupant safety apparatus, the safety apparatus including an inflatable airbag which restrains a vehicle occupant when inflated by the gas, and a housing which contains the gas generating material and which has at least one gas exit opening, said filter comprising: a filter sheet having a first section, a second section, a side surface extending across said sections, and a plurality of gas flow openings at each of said sections, said filter sheet comprising an imp...
