Abstract:
Electrical resistor heating element with a flat resistive layer containing a resistive mass and disposed between at least two electroconductive layers formed as flat electrodes and disposed congruently, such that a sandwich element results where each conductive layer can be connected with one feeder line, characterized in thatâ€”at least in the border regionâ€”at least a first recess in the first electroconductive layer is offset relative to a second recess in the second electroconductive layer in such a way that the two recessesâ€”when seen in superimposed projectionsâ€”are mutually separated, so that each of the electroconductive layers can be contacted selectively and connected mechanically on both sides with the corresponding feeder line in the region of a corresponding recess in a direction normal to the conductive layers, while the contacted conductive layer is accessible on one side through one of the recesses and through the resistive layer.
