Disclosed is a fluid conduit () comprising a pipe () and a conduit connector () which is connected to the electrically conductive pipe (). In order to be able to keep the risk associated with electricity being on the fluid line as low as possible with little effort, an electrical connecting element () which is electrically connected to the pipe () is provided in the region of the conduit connector ().

Fluid conduit

A pipe arrangement includes a pipe and a pipe coupling having on a front face a peripheral groove with a groove bottom. The pipe is insertable within the groove and weldable to the pipe coupling. At least one through opening structured and arranged to connect the groove to the surroundings of the pipe coupling.

Pipe arrangement

A steering-wheel skeleton has a hub, spokes, and a rim made in one piece out of a single sheet-metal blank and provided with its final shape by separation and bending without machining. The hub is provided with a cone facing the vehicle. The spokes, which extend up and out, are provided with unthreaded bores, cutouts, or threaded bore for attaching an airbag module. A nut can, if necessary, be forced into one cutout. The hub can be reinforced by using two layers of the material.

Sheet-metal steering wheel

The hub and spoked of a steering wheel consist of a synthetic thermoplastic resin and just as the rim are covered with a layer of a deformable plastic. To provide a steering wheel which is light in weight and has a high temperature stability, the hub and spokes consist of a polyamide which has been modified with elastomers and fibers.
