Operating panel for a motor vehicle air-conditioning system

Claim 1

An operating panel for a motor vehicle air-conditioning system, comprising: a heating device; a cooling unit with a switch for switching the cooling unit on and off; an air blower with a speed control device for setting the blower speed; a damper with a damper movement controller for moving the damper between a fresh air position and an air recirculating position, wherein the damper movement controller is an electromechanical actuating member; a blower speed actuating element connected to the speed control device for selectively setting the blower speed; an air temperature actuating element for selectively setting the incoming-air temperature; an air distribution actuating element for selectively setting air distribution in a vehicle passenger compartment; a damper actuating element for selectively actuating the damper; a maximum air cooling actuating element for maximum air cooling of the air in a vehicle passenger compartment; and a coupler connecting the maximum air cooling actuating element to the damper movement controller, to the blower speed control device, and to the cooling unit switch so that actuation of the maximum air cooling actuating element sets the damper to the air recirculating position, the blower to a predetermined speed, and the cooling unit to a maximum output, wherein the coupler comprises at least one electric switch actuated by the maximum air cooling actuating element and electric connecting lines to the blower speed control device and the damper controller, the electric switch being provided with a contact for switching the electromechanical actuating member for moving the damper to the air recirculating position.
