Abstract
An airbag assembly may include an airbag and an inflator that provides inflation gas to inflate the airbag. A filter module may be positioned such that inflation gas exiting the inflator must first pass through the filter module. The filter module may be formed of a sheet of metal that is wrapped into a generally spiraling tubular shape. The filter module may have an inner layer, an intermediate layer, and an outer layer. The intermediate layer generally encircles the inner layer, and the outer layer generally encircles the inner layer and the intermediate layer in a spiraling fashion. The inner layer, the intermediate layer, and the outer layer each may have a pattern of holes and dimples that are separate from and/or displaced from each other. The dimples may protrude toward an adjacent layer to maintain spacing to enable relatively unrestricted gas flow from the holes of the inner layer through unaligned holes of the intermediate layer and the outer layer. The resulting tortuous gas flow path may help to slow, cool, and/or purify the gas before it exits the inflator.
