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.
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:
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:
Inflatable airbags often have inflation gas deflectors to protect the airbag or airbag seams from sustaining damage from the force of the inflation gas and to direct the inflation gas to predetermined areas of the airbag. The deflectors can be coupled to the airbag so that the deflector projects radially away from the surface of the airbag to which the deflector is coupled. The deflectors can also have a plurality of vent apertures.
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:
A new type of airbag cover and method for making the same is described herein. The airbag cover will generally have an insert that includes one or more logos, indicia, symbols, trademarks, etc. that denote the vehicle manufacturer. A base will then be molded around this insert. The base and the insert are made of the same (or substantially the same) materials. However, the color used for the insert will differ from the color used for the base. The fact that different colors are used means that the indicia on the insert will be visually appealing and “eye-catching” to the consumer. Once the base is molded to the insert, these two features will chemically bond together. The indicia and the base material may be chemically and/or mechanically bonded together. Generally, this bonding is accomplished such that there is a continuous fit between the insert and the base.
Abstract:
A fabric deflector system is disclosed for use with airbags and airbag systems. The system comprises a deflector panel attached to an airbag cushion body. The deflector panel is attached to the airbag cushion body in a position such that the deflector panel at least partially deflects the inflation gas received from the inflator during inflation of the airbag cushion. The deflector panel comprises a plurality of arms extending radially outward from the inflator opening and at least partially deflects the inflation gas through the arms.
Abstract:
An air bag device that includes 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 exits 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. The edge of the aperture is configured such that the cross-sectional area of the aperture that is proximate to the exterior surface of the wall is larger than the cross-sectional area of the aperture proximate to the interior surface of wall. The edge includes an angled portion configured such that opposing sides of the aperture have an angle &agr; therebetween in the range of about 20 degrees to about 145 degrees. The aperture has a diameter d1 proximate to the interior surface of the wall and is configured so that the diameter d1 and wall thickness t have a ratio d1 to tin the range of about 0.5 to about 4. An alternate embodiment of the air bag device comprises an aperture defined by an edge that is configured so that the cross-section of aperture is non-smooth and causes turbulence in the gas stream.
