A control circuit for a vehicle seat having at least one heating element and at least one fan is provided. The control circuit includes a two-pole switch having two synchronously actuated switch elements. The switch elements are operatively connected to the heating element and the fan to operate the heating element and the fan in a first operating mode wherein only the heating element is active, and a second operating mode wherein both the heating element and the fan are active. When two heating elements are employed, the two heating elements are connected in parallel by the switch elements in the first operating mode and are connected in series by the switch elements in the second operating mode.

Electric circuit to control an air-conditioned seat

A vehicle seat ventilating system comprising at least one fan ( ) arranged in the seat ( ) and controlled by a central control unit ( ) and an electric control unit ( ) associated with each fan ( ) for actuating the respective fan in response to control signals from the central control unit ( ), wherein each electronic control ( ) is arranged at the respective fan ( ) Thus, each of the fans ( ) arranged in the vehicle seat ( ) has its own electronic control unit ( ) that is located at the fan ( ) and is connected to the central seat control unit ( ) by a data line ( ) that transmits control signals. The power supply currents required to drive the fan ( ) are regulated directly in the electronic control unit ( ) located at the respective fan ( ). Thus, each of the fans ( ) arranged in the vehicle seat ( ) has its own electronic control unit ( ) located at the fan ( ) and is connected to the central seat control unit ( ) by a data line ( ) that transmits control signals. In this way, the number of fan units controlled by the central control unit ( ) can be readily changed according to design criteria as a result of the standard data bus interface.

Vehicle seat ventilation system

A ventilation device for the seat ( ) of a motor vehicle ( ) which has an electrically driven fan ( ), the vehicle ( ) having a solar cell arrangement ( ) which, with the vehicle ( ) turned off, provides a supply of solar generated power for operation of the fan ( ).
