Abstract (en)
[origin: DE19826544C1] The invention relates to a resistor heating element (1) comprising a resistive sheet layer (2) which contains a resistive material (preferably an electroconductive polymer) and is placed between at least two electroconductive layers (3, 4, 7) shaped as plane electrodes in order to form a sandwich element. Each layer (3, 4, 7) can be connected to a power supply line via contact studs. At least one recess (5) in the first electroconductive layer (3) is shifted relatively to a recess (6) in the second electroconductive layer (4) so that the two recesses (5, 6) (viewed in projection one on top of the other) are placed at a distance from each other. These recesses (5, 6) are located in the border region of the electroconductive layer (3, 4, 7) and at least one contact stud (34) can come into electrical contact and be mechanically connected to the other electroconductive layer (3) in the region of the recess (5) of a first electroconductive layer (4) via the resistive layer (2). Preferably, the contact stud (34) can also be connected to the resistive layer (2), especially through a crimp connection.
