  • Airbag filter assembly and method of assembly thereof
    Patent number: 5702494
    Abstract: An efficient, light-weight airbag inflation filter includes a gas-permeable, substantially rigid support tube having a plurality of uniform perforations therethrough. A filtering element formed from a continuous inorganic ceramic yarn or roving is helically cross-wound around the support tube to form one or more layers covering the perforations of the support tube. A wire screen, having openings therethrough smaller than the perforations in the support tube, is disposed between the filtering element and the support tube to act as a gas diffusion layer for the gases passing through the inflation filter.
