Abstract
The invention relates to a device for transmitting electric current between two components, which twist in relation to one another, of a steering device for motor vehicles. The inventive device comprises a rotor which is assigned to the steering wheel and which can turn together with the same, a stator which is assigned to a stationary subassembly of the motor vehicle, and at least one flexible printed circuit board which runs from the rotor to the stator. When the steering wheel is turned, said printed circuit board can, according to the direction of turning, be wound onto a winding element or unwound therefrom. In addition, the printed circuit board comprises a flat flexible support on which the conductor tracks run from the stator to the rotor. According to the invention, each opposing surface (28, 29) of the flexible support (30) is provided with conductor tracks (40a, 40b) running from the stator to the rotor.
