Abstract
A flexible heating element for a vehicle seat or the like includes at least one flexible heating resistor element and at least two flexible supply electrodes arranged at a distance from each other and at least partly embedding the heating resistor element between them to form a layered structure. The flexible heating resistor is formed of a material having a positive temperature coefficient (PTC) effect. The layered structure includes a plurality of recesses formed therein defining a plurality of webs, the webs and recesses resulting in a net-like structure.
