Abstract
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.
