Kraftfahrzeuge sind oftmals mit einer Sitzheizung ausgestattet, deren Bedienung über ein im Innenraum des Kraftfahrzeugs angeordnetes Betätigungselement erfolgt. Dazu kann im Sitz ein Temperaturfühler integriert sein, der die Sitzheizung beim Erreichen einer bestimmten Solltemperatur wieder ausschaltet. Da Sitzheizungen eine relativ hohe Leistungsaufnahme besitzen (ca. 100 W) und daher das Bordnetz bzw. die Batterie des Kraftfahrzeugs belasten, werden diese nur bei laufendem Motor (Klemme 15) betrieben. Trotz der hohen Leistungsaufnahme dauert es jedoch eine gewisse Zeit, bis die Fahrzeuginsassen die Heizwirkung der Sitzheizung verspüren.motor vehicles are often equipped with a seat heater whose operation is over in the interior of the motor vehicle arranged actuating element takes place. To Can in the seat a temperature sensor be integrated, the seat heating when reaching a certain Set temperature switches off again. Since seat heaters a relative have high power consumption (about 100 W) and therefore the electrical system or load the battery of the motor vehicle, these are only operated with the engine running (terminal 15). Despite the high power consumption takes However, it takes some time for the vehicle occupants to heat up feel the seat heating.
