Abstract
A vehicle seat has a cushion, a seat-heating arrangement integrated in the cushion, a ventilation device for the through-ventilation of the cushion over its surface area, and a control unit for controlling the seat-heating arrangement and ventilation device. For the purpose of shortening the response time of the seat-heating arrangement when the latter is switched on, the control unit activates the ventilation device as the seat-heating arrangement is switched on in each case, the control operation, in the control unit, which causes the seat-heating arrangement to be switched on preferably being such that the seat-heating arrangement and ventilation device are switched on at full power and the power of the ventilation device is reduced asymptotically to a predetermined end value within a predetermined time interval.
