Vehicle seat ventilation system
摘要:
A vehicle seat ventilating system comprising at least one fan (4) arranged in the seat (7) and controlled by a central control unit (1) and an electric control unit (3) associated with each fan (4) for actuating the respective fan in response to control signals from the central control unit (1), wherein each electronic control (3) is arranged at the respective fan (4) Thus, each of the fans (4) arranged in the vehicle seat (7) has its own electronic control unit (3) that is located at the fan (4) and is connected to the central seat control unit (1) by a data line (2) that transmits control signals. The power supply currents required to drive the fan (4) are regulated directly in the electronic control unit (3) located at the respective fan (4). Thus, each of the fans (4) arranged in the vehicle seat (7) has its own electronic control unit (3) located at the fan (4) and is connected to the central seat control unit (1) by a data line (2) that transmits control signals. In this way, the number of fan units controlled by the central control unit (1) can be readily changed according to design criteria as a result of the standard data bus interface.
