Abstract

A temperature-controlled seat has at least one seat contact surface (31) whose outer side faces the passenger in the seat. Conditioned air is supplied to the inner side region of the seat contact surface (31) by means of an air conditioning device (18). An electrical heating element is used to heat the seat contact surface (31) in the inner side region of the seat contact surface (31). A thermal sensor (28) detects the temperature in the region of the seat contact surface (31). To rapidly adjust the seat temperature to a preset desired temperature independently of ambient conditions, a control device (20) is provided which is linked to both the air conditioning device (18) and the electrical heating element (26) and which regulates them to a preset desired value for temperature as a function of the temperature measured by the thermal sensor (28).
