Abstract:
Seat heater with at least one electric sheet-type heating element (10) made of flexible high-resistivity material, the heating element having opposite sides to which main electrodes (13A, 13B) are directly connected for the purpose of heating the sheet-type heating element (10), characterized byan additional feature (18A, 18B) for heating basically at least a partial area (SH) o f the sheet-type heating element (10) with increased heating density, anda switching device for changing from heating the partial area (SH) with the additional feature (18A, 18B) to a basically all-over homogeneous heating process of the sheet-type heating element (10) with regular heating density through the main electrodes (13A, 13B), or through the main electrodes (13A, 13B) and the additional feature (18A, 18B).
