    摘要： A filter arrangement for an airbag gas generator of the type utilizing gas-producing propellant charge to generate gas to inflate an airbag, and having a filter chamber exhibiting contoured interior surfaces. A gas permeable filter material with a large effective filter surface is disposed in the filter chamber in such a manner as to substantially completely fill up the filter chamber and to contact substantially all of its contoured interior surfaces. The filter material comprises a circular knitted wire knit, rolled up and pressed into a shape corresponding to the shape of the filter chamber.

    摘要： A gas generator, which can be used to inflate an airbag, that has a perforated outer housing wall, a fuel chamber, an expansion chamber which adjoins the fuel chamber and is connected to the fuel chamber via openings, includes a surrounding filter resting against the outer housing wall. A filter tube holds and supports the filter. To provide a secure and uniform sealing of the edge of the filter along the entire circumference of the outer housing wall, a ring-shaped clamping device is provided between the filter tube and the edge of the filter. The clamping device presses the edge of the filter against the outer housing wall.
