  • Rivetless cushion retaining ring with tabs which lock the ring in place after rotation
    Patent number: 5501484
    Abstract: This invention relates to a clamping structure for assembling an automotive air bag to an automotive air bag inflator. The clamping structure includes an annular retainer ring and module housing. Integral "L" shaped tabs or studs descending from the annular retainer are designed to pass through radial slots in the air bag and module housing. The tab or stud is formed to have an "L" shape with the short leg of the "L" having a slight angle. Then as the retainer is rotated into place, the short leg of the "L" shaped tab or stud will be forced into contact with the housing and clamp the assembly together.

  • Floating, serviceable horn switch, air bag modules
    Patent number: 5239147
    Abstract: A floating, serviceable, horn blowing switch consists of a shoulder bolt and stud which in conjunction with an assembly retainer and lock nut hold an air bag module assembly to the steering wheel of an automotive vehicle. The horn switch assembly includes a pre-stressed compression spring and two concentric housings that are arranged to snap together. The housings act as an electrical insulator and house the compression spring and electrical contacts. Lead wires connect the electrical contacts to a power source and the horn mechanism. The electrical contact gap is governed by the vibration requirements of the vehicle and stiffness of the compression spring.

  • Driver cover integral horn switch with solid reinforcement structure
    Patent number: 5186490
    Abstract: The cover for an inflatable occupant restraint system for a motor vehicle contains a slot in the upper wall thereof into which a thin or membrane type switch assembly is inserted. The slot in the cover is positioned between a soft outer cover material (such as urethane, vinyl or polyester) and a solid reinforcement material (such as molded thermoplastic material). The solid reinforcement material provides for the slot into which to insert the switch and also for positioning and support of the switch, and in addition, for another slot through which electrical leads to the switch are inserted. The solid reinforcement material also provides for cover strength, as well as the cover rigidity that is required to provide a reaction surface for switch actuation.
