Abstract:
Disclosed are embodiments of an airbag cushion and related airbag modules including a plurality of flaps that may be used to secure the airbag within a module housing. In one embodiment of the invention, first and second flaps are connected with the airbag cushion. The airbag cushion is adapted to be condensed into a compact configuration wherein the first flap extends adjacent to the second flap and in at least approximately the opposite direction as the second flap.
Abstract:
The applique film airbag cover includes a substrate and an applique film. The substrate includes a tear seam to permit the emergence of a contained inflatable cushion. The applique film is disposed on an exposed surface of the substrate and is disposed across at least one tear seam in the substrate. The substrate may include contours that can be aligned with an emblem design on the applique film to produce a three-dimensional emblem. In response to expansion of the contained cushion, the tear seam and applique film rupture to permit the cushion to emerge through the cover.
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:
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.
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:
Flangeless inflators include a body comprising a base member and a diffuser member coupled together, where the body is devoid of a lateral inflator-coupling flange. At least one fastener is coupled to the base member of the body. In an inflatable airbag system, the flangeless inflator is coupled to an airbag cushion, as well as to a steering wheel armature. In forming flangeless inflators, a body is formed that is devoid of the lateral inflator-coupling flange, and at least one fastener is attached to the body.
Abstract:
A steering wheel assembly that receives an airbag may include a steering wheel framework. This framework may include a back cover and a first attachment feature. The steering wheel assembly may include an airbag cover having a second attachment feature for engaging the first attachment feature to directly attach the airbag cover to the steering wheel framework. This attachment may be accomplished without the use of an airbag housing. In some situations, the framework further includes an armature. The first attachment feature is positioned either on the armature or on the back cover.

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 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. This firmly secures the cushion and cover to the inflator, and completes assembly of the module with the mounting step. This design further permits the use of a simplified cover flap which is easier to produce.
