Abstract
A mounting arrangement for an airbag cushion. The cushion is provided with a mounting portion adjacent the cushion mouth. The mounting portion is connected about the periphery of the mouth, preferably on the interior, and extends peripherally outward from the mouth to a collar. This collar is received and secured between a mounting plate and the inflator, and includes holes to receive the bolts extending between the mounting plate and the inflator. The mounting portion may take many forms. A first embodiment includes a plurality of fabric sheets secured at their inner edge about the periphery of the cushion mouth. In a second embodiment, the fabric sheets include overlapping tabs which pass through the mouth of the cushion. In a third embodiment, strips of fabric are formed into a loop, with one longitudinal end being secured to the mouth of the cushion. The sheets may be oriented and arranged such that gas vents between the sheets to alter the inflation of the cushion.
