Abstract: A plug for gas generators of air bag impact protection systems has current paths formed by sheet metal strips and an inductance coil in one of both interrupted current paths that form two poles. One of the current paths is U-shaped; its branch opposite the counter-current path (4) is interrupted to form two inner poles (1, 2) and acts as a mechanical support for the inductance coil (5) that electrically bridges the interruption, and the other branch (3), located next to the counter-current path (4), forms together with the counter-current patch (4) plug pins (6, 7) that extend outwards. The plug pins (6, 7) are formed by bending the T-or forked-shaped ends of the current paths (3, 4). The inductance coil (5) is arranged in a housing and is provided with electric connections that can be directly connected to the inner poles (1, 2). In order to manufacture this plug, a preform is first cut out of a sheet metal web.

Abstract: A current conductor apparatus for connecting the stator of a steering column to a rotor of a steering wheel. The stator and rotor are guided concentrically with respect to one another by rotation guides and are provided with contacts for establishing an electrical connection between them. The rotor and stator are stapled to one another without being aligned by the guides. The axial and radial play between them is limited, and they may be fastened to the steering wheel and column without rotating or contacting one another. In order to facilitate the center adjustment of the apparatus, stator is provided with an attachment with a tapped hole for a screw. The screw and spring are used to hold clamp, which projects into a corresponding bore on rotor with its one elbow end and extends up to an area lying on shoulder of stator with its other end. Rotor and stator are provided with stops to limit the axial play.
