  • Patent number: 6802531
    Abstract: A steering wheel has a skeleton with a foamed sheathing, a hub, spokes and a steering wheel rim. A gas bag module is inserted in a central recess of the steering wheel. The gas bag module has a cover cap at the side facing the driver. For actuating a horn switch, the module is movable in the direction of the steering wheel axis relative to the steering wheel. A movement gap is formed between the cover cap and the foamed sheathing. Mounting studs on the skeleton extend parallel to the steering wheel axis. The positioning of the mounting studs is defined by the foamed sheathing. The mounting studs have free ends which are slidingly accommodated in guide recesses provided in the cover cap.

  • Patent number: 6257615
    Abstract: An impact protection device for motor vehicle drivers includes a steering wheel, an air bag module and a module cover. The steering wheel, the air bag module and the module cover each form a separate assembly unit. Two mounting studs project from the module cover towards the steering wheel. The module cover and the air bag module are connected to the steering wheel by means of the mounting studs. The mounting studs are attached to the steering wheel. Fastening means are provided on the end of each mounting stud. A washer of insulating material, a coil spring and a mounting flange of the module cover are clamped between the flange of the mounting stud and the fastening means. Support for an electrical switch contact is embedded in the washer of insulating material and a mass contact of an electrical switch is provided on the mounting flange of the module cover.
