Flat heating element
First Claim
1. An electric heating element comprising:
- a. at least one flat heating resistor for disposed near a surface to be heated; and
b. at least one electrode for feeding a current into the flat heating resistor, the at least one electrode comprisingat least two contact conductor strands includingan elongated contacting region;
wherein, within the elongated contacting region of the electrode feeds a current into the flat heating resistor, wherein the at least two of the contact conductor strands are at least locally in contact to one another and to the heating resistor, and wherein further at least one point at least one of the contact conductor strands at least locally extends directionally generally parallel to the direction of the electrode and at least one other contact conductor strand at least locally extends angular to the direction of the electrode or of the elongated contacting region or both.

Abstract
The present invention pertains to an electric heating element with at least one flat heating resistor to be arranged near a surface to be heated, and at least one electrode that serves to feed a current into the heating resistor and features at least two contact conductor strands that are, at least locally, connected to one another and to the heating resistor, at least in an elongated contacting region. The invention proposes that at least at one location along the electrode and/or the contacting region at which at least one of the contact conductor strands, at least locally, extends parallel to the direction of the electrode, and/or the contacting region, at least one additional contact conductor strand, at least locally, extends at an angle thereto.

11. An automotive vehicle having at least one seat that is heated by an electric heating element comprising:
-
a. a flat carrier; b. at least one electrode comprising a conductor network arranged on the flat carrier, including at least two contact conductor strand bundles that are generally curved and generally parallel to each another but phase shifted relative to each other such that they contact one another in at least one contact point, such that in the event of local failure, heating current can be distributed to adjacent heating conductors contacting the conductor network; and c. at least one connecting line associated with the carrier for supplying a current from a current source to the conductor network. - View Dependent Claims (12, 13, 14)
