Abstract
A heating device has a sheet-like heating element and a holding device for the heating element, wherein the heating element is held along an outer edge on the holding device and, by way of at least 70% of its surface area, runs freely within the holding device. The heating element has a weave which at least partially contains heating conductor material. Therefore, warp threads can advantageously be composed of electrically conductive heating conductor material, and weft threads can be composed of carbon fibre or ceramic fibres. The heating element can be centrally supported or be provided with a structuring over its surface area, which structuring stabilizes the heating element, for example can be corrugated.
