  • Patent number: 5584507
    Abstract: Fabric coatings and methods reduce the toxicity of effluent gases produced by combustion of nonazide gas generating compositions used to inflate vehicle occupant restraint systems. Passing the effluent gases into a coating comprising an alkaline material reduces the concentration of toxic oxides of nitrogen therein. Further, passing the effluent gases into a coating comprising an oxidation catalyst reduces the concentration of carbon monoxide therein.
    Type: Grant
    Filed: October 31, 1994
    Date of Patent: December 17, 1996
    Assignee: Automotive Systems Laboratory, Inc.
    Inventors: Paresh S. Khandhadia, Daniel G. Zelenak
  • Patent number: 5553888
    Abstract: A snap-on steering wheel assembly (10) is provided with an integral air bag housing (38) for supporting an air bag (50) therein. The assembly includes a steering wheel having a hub. An inflator (100) is threadably connected to an insert member (60) and longitudinally extends from the hub or insert member. A collar (80) mounted relative the insert provides a snap-fit engagement to a steering column (12).

  • Patent number: 5547217
    Abstract: An air bag inflator is manufactured by sandwiching a wire mesh filter between a pair of flat elongated perforate strips of steel, thereafter rolling the sandwiched steel strips and wire mesh concomitantly to form a right circular cylindrical tube with the edge portions of the steel strips orientated in juxtaposed relation to one another, respectively; and welding the juxtaposed edge portions of the strips by a common weld that extends radially across the edge portions of both of the steel strips.

  • Patent number: 5062664
    Abstract: An assembly comprising:a hollow cylindrical member or can including an opening into which a gas generator may be inserted, the gas generator of the type responsive to a control signal, for generating gas to inflate an air bag. The assembly including the air bag, for protecting, when activated, an occupant of a vehicle, comprising an inflatable bag or sack, disposed in a compacted or stored condition, during periods prior to deployment, proximate a side of the cylindrical member containing at least one aperture, the inflatable bag, including an open end disposed about the cylindrical member to receive the gas and including relatively opposing flaps extending from proximate the open end and adapted to envelop the cylindrical member, the flaps, proximate a side of the cylindrical member, away from the at least one aperture, disposed in an overlapping, condition, one to the other. A band of tearable material is provided to secure the air bag in its stored or predeployment condition.

  • Patent number: 5022675
    Abstract: A method of folding an air bag and an air bag having a main panel 20 defining a top (26), front (24), and bottom (28) portions and side panels (44a,b) the top and bottom portions defining a neck 30 narrower than the front portion; comprising the steps of: laying bag with bottom portion (28) of main panel (22) flat and as fully extended as possible; flattening the front portion (24) of the main panel (20) to over the flattened bottom portion to form a first lateral extending fold (80) between the bottom (28) and front portions (24) of the bag; maintaining a portion of the front panel (24), proximate the bottom panel (28), relatively flat and folding over the front portion with the top portion to define a second lateral fold (82) between a top portion and the front portion with the top portion flattened and extended as fully as possible, aligning edges (86) of opposing top and bottom portions; placing bag material towards a centerline (70) of bag to form on each side of the bag (20) first (90) and second (92) e
