Abstract
An integral airbag cushion retainer, filter and diffuser for use with an inflator assembly for generating inflation gas, a first filter material, a second filter material and an inflatable airbag cushion, as part of an inflatable restraint system. The integral airbag cushion retainer, filter and diffuser comprises a shaped plate member which has a top panel that joins to a filter chamber wall extending to a radially extending airbag cushion retaining ring. The shaped plate member fits over and encloses a portion of the inflator assembly comprising a plurality of gas exhaust openings, with the retaining ring attaching to the inflator assembly, retaining the airbag cushion therebetween in a gastight manner. A filter chamber, enclosing the gas exhaust openings and retaining the first filter material, is formed by the inflator assembly, the top panel and the filter chamber wall. An outer filter chamber, retaining the second filter material is formed by the filter chamber wall, the retaining ring and an outer filter chamber wall extending upwardly from the cushion retaining ring to an outer edge of the shaped plate member. The outer edge is either folded or crimped towards the top panel and filter chamber wall, retaining the second filter material within the outer filter chamber. A plurality of gas port openings in the filter chamber wall connect the filter chamber to the outer filter chamber, while the outer filter chamber has a gas delivery passage for delivering and diffusing generated gas into the airbag cushion.
