Abstract
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.
