Abstract

The invention relates to a heating device for a moveable part of a motor vehicle such as an automobile which can be held, such as a steering wheel. The heater is connected to a source of electrical energy in a stationary part of the vehicle by a contact unit having a stator and a rotor. A voltage converter of the heating device is provided in the stationary part of the vehicle, before the contact unit or in the stator of the contact unit. The voltage converter enables the generation of a higher voltage than the normal 12 volt standard voltage of the vehicle.
