  • Patent number: 10145407
    Abstract: A wave washer includes an annular member surrounding an opening arranged to receive a pipe axially therethrough, the annular member having a plurality circumferentially spaced holes formed therein. The wave washer also has associated with it at least one spring portion protruding axially from the annular member between two of the holes. The wave washer can be used in a pipe joint to join a first pipe and a second pipe, each having a pipe end having a pipe flange and an adjacent sealing flange. The wave washer is positioned against an inner side of the pipe flange of the first pipe. The wave washer and the flanges of the first and second pipes are fastened based on the deflection of the annular member of the wave washer.

  • Patent number: 9333937
    Abstract: Airbag covers with stress relief features are disclosed. An airbag cover includes a cover face that opens during deployment and one or more sidewalls extending from the cover face to engage a housing of an airbag assembly. One or more tear seams formed in the airbag cover are rupturable upon expansion of the airbag to form the cover face as a hinged door that opens. Excess force can cause a tear seam to propagate through a stop, creating a risk that a portion of the airbag cover will separate from itself or the housing. Stress relief features are disposed in a sidewall to dissipate excess deployment energy and limit undesired breakage of the airbag cover or continued tearing of the tear seam beyond a tear seam stop. The stress relief features disclosed include tear seams and slits oriented transverse to front cover tear seams.

  • Patent number: 6394491
    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.

  • Patent number: 6213501
    Abstract: An improved ignition system for vehicle airbags is described. This invention includes a novel means for venting igniter material gases in such a manner as to more evenly distribute the flow in a more disperse manner, thereby permitting the gas generant to burn more uniformly throughout the generant bed. This invention by venting igniter gases more efficiently produces improved airbag ballistics, namely lowered average airbag deployment delay and increased consistency of operation.

  • Patent number: 5876062
    Abstract: A two-walled, dual chamber, inflator for inflation of an automotive airbag in the event of a collision is provided. The inflator includes a simplified housing with two internal chambers, including a central chamber and a coaxial outer chamber. The central chamber houses both the solid fuel gas generant bodies and a electrical igniter having a reliable single-stage ignition train in direct contact with the generant bed. The single-stage igniter includes a resistance wire submersed in the generant bed along a convoluted path. Multiple points of direct contact are established between the igniter wire and gas generant over a substantial portion of the generant bed, which leads to more uniform and efficient ignition of the gas generant. To get sufficient surface area for the generant to contact the igniter wire, the gas generant bodies are formed in relatively small sizes of about 0.05 inch or less, which, in turn, limits the selection of gas generant materials to those having low burn rates of about 0.

  • Patent number: 5829785
    Abstract: A gas generating inflator assembly for a vehicle safety restraint system including an inflator housing having two walls, an inner wall and an outer wall. The inner and outer walls form a combustion chamber therebetween. A filter pack is disposed within the combustion chamber along an inner diameter of the outer wall. Gas generant is also disposed within the combustion chamber. An internal structure is disposed within the combustion chamber for diffusing the ignitor blast and retaining slag produced by the ignited gas generant. The internal structure is spaced from the filter pack and the inner wall such that a portion of the gas generant is located between the internal structure and the inner wall and another portion of the gas generant is located between the internal structure and the filtration pack.

  • Patent number: 5779267
    Abstract: Components of a vehicle airbag gas generator, or inflator, are coated with reactivity resistant materials to protect them from deterioration caused by contact with the high temperature, reactive gases generated by recently developed non-azide high reactive temperature gas generating materials. Suitable coatings include those produced from ceramics and reactivity resistant metals. These coatings also provide long term protection of the components from deterioration caused by the environment/atmosphere within the inflator.

  • Patent number: 5673483
    Abstract: An improved method for fabricating a filter for use in automotive air bag inflators which comprises forming a hollow cylindrical inner core or combustion screen of filter material and outer filter layers wound outward from the surface of the core so as to be maintained in cylindrical relation thereabout. This invention is specifically directed to an improved filter which does not include a perforated support tube and relies on only the interior combustion screen for support in the final wrapping of the remaining filter structure.
