Abstract
An electrically operated heating device, in particular for a heating or air conditioning system of a vehicle, is provided, comprising a heating register with a layered heating element, for converting electrical energy into heat, and two electrically insulating and heat-conducting insulating layers, which respectively make contact, at least in certain regions, with one side of the layered heating element. The insulating layers and the layered heating element are braced with one another, an abrasion-counteracting sliding layer being arranged between at least one of the insulating layers and the layered heating element. Alternatively or in addition, at least one of the insulating layers and the layered heating element have, at least in the region of their mutual contact surfaces, a material pairing with which the abrasion of the contact surfaces goes below a predetermined limit value.
