Abstract: An air bag device that comprises an air bag cushion, a diffuser canister, and a gas generation inflator. The diffuser canister is attached to the air bag cushion and has walls configured to define an interior space therein. The walls of the diffuser canister have an interior surface, an exterior surface, and a wall thickness t. At least one of the walls has an aperture formed therethrough in communication with the interior of the air bag cushion. The gas generation inflator is configured to rapidly create a gas that exists the diffuser canister through the aperture so as to fill the air bag cushion. The aperture is defined by an edge extending between the interior and said exterior surfaces of the wall that is configured to diffuse the gas exiting the diffuser canister through the aperture.

Abstract: Arrangements and methods for attaching an airbag cushion are provided wherein an attachment opening of the airbag cushion is clamped between an inflator and an airbag retainer which previously had been floatingly confined within the body of the airbag cushion.

Abstract: Arrangements and methods for attaching an airbag cushion wherein the airbag cushion "floats" or is movable relative to an airbag module element extending through an opening in the cushion with a first end of the module element disposed within the cushion inflatable body and a second end of the module element extending out of the cushion inflatable body. Upon deployment of the corresponding airbag cushion, such floating or movable attachment can help avoid stress concentrations and complications associated therewith.

Abstract: An airbag module featuring a reduced number of components is disclosed. The assembly of the module is simplified by the fewer number of components involved and by the use of a single fastener to hold the major components together as a module. The module comprises an inflator, an inflatable cushion, an optional cover and an optional insulator, all of which are held together by a single clamp.

Abstract: An airbag deflection mount for mounting an airbag cushion to an airbag module and for deflecting hot inflation gas away from a throat of the airbag cushion. The airbag deflection mount includes a generally flat retainer ring for securing a collar of the airbag cushion around an inflator of the airbag module that produces and expels the inflation gas from a plurality of inflation ports for inflating the airbag cushion upon a vehicle collision. The airbag deflection mount also includes a plurality of deflectors extending upwardly from the retainer ring and positionable, spaced-apart from the inflator, between the plurality of inflation ports of the inflator and the throat of the airbag cushion. The plurality of deflectors deflect hot inflation gas away from the throat of the airbag cushion and substantially prevent the throat of the airbag cushion from being burned by the hot inflation gas.

Abstract: An airbag module combining assembly and mounting components and steps. The module includes an inflator having a mounting flange. The cushion mouth rests upon a top side of the flange. A rigid retaining member rests above the cushion mouth to secure the cushion to the flange. The retaining member includes studs which extend through mating holes in the cushion and flange. The free ends of the studs extend beyond the bottom of the flange. A cover fits over the folded cushion and includes a plurality of flaps extending downward. The ends of the flaps are folded under the flange and fit over the studs. Temporary restraints, such a friction lock washers are secured over the studs to secure the cushion, inflator and cover flaps between the retaining member and temporary restraints. The partially assembled module may be shipped in this condition. The extending free ends of the studs may then be inserted into mounting brackets in the vehicle, and permanent nuts fixed thereon.

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.

Abstract: A closure for an air bag deployment opening is provided. The closure includes at least one integral reinforcement rib and/or appropriately thickened hinge section to prevent undesired tearing of the closure.

Abstract: A closure for an air bag deployment opening is provided. The closure includes at least one stress concentration feature adapted to form, under the influence of an inflating bag, a selected initial opening in the face portion of the closure for the deployment of the bag therethrough.
