Abstract

An arrangement for wireless transmission of electrical signals in a motor vehicle maintains a cassette equipped with a stator (3) and a rotor (4) rotatably mounted in the stator (3) is arranged on the steering wheel of the motor vehicle, where the cassette has at least one electrical line extending in windings mounted between stator and rotor. The stator of the cassette is connected to the steering column, while the rotor is connected to the steering wheel. The transmitter (6) is arranged in the immediate vicinity of the stator (3) of the cassette and the receiver (7) is mechanically connected to the rotor (4) of the cassette and electrically to at least one electrical line (9) with a display (8) for displaying received signals.

Claims

1. Arrangement for wireless transmission of electrical signals in a motor vehicle, said motor vehicle equipped with a steering wheel which is capable of turning in a stationary steering column, wherein a transmitter for the electrical signals is mounted on the steering wheel and a receiver for the electrical signals is mounted stationary in the motor vehicle, said arrangement comprising:

a cassette equipped with a stator and a rotor rotatably mounted in the stator, wherein the cassette includes an electrical line mounted between the stator and the rotor and extending in windings, wherein the line is at one end secured to the stator and with the other end to the rotor, wherein the stator of the cassette is connected to the steering column, while the rotor is connected to the steering wheel;

wherein said transmitter is arranged in the immediate area of the stator of the cassette on a stationary part of the motor vehicle; and

wherein said receiver is connected mechanically to the rotor of the cassette and electrically by means of an electrical line to a display for displaying received signals.

2. Arrangement according to claim 1, wherein the receiver as well as the display are connected for their current supply electrically conductively to the line of the cassette.

3. Arrangement according to claim 1, wherein the transmitter is mounted directly on the stator of the cassette.

4. Arrangement according to claim 1, wherein the display is constructed as a screen.
