Abstract
A vehicle seat including at least one pad ( ) having an air-permeable surface area ( ). In the region of the air-permeable surface area ( ) of the pad, an air-permeable heating element ( ) is arranged to heat the surface area ( ) of the pad. A fan unit ( ) blows air through the heating element ( ) and the surface area ( ) of the pad. A first temperature sensor ( ) detects the temperature of the surface area ( ) or of the heating element ( ). A second temperature sensor ( ) detects the temperature of the air aspirated by the fan ( ). A fan regulator ( ) regulates the volume flow of air as a function of the temperature detected by the second temperature sensor ( ).
