Vehicle air handling system

A vehicle air handling system comprising:

• a user input interface;
• an air duct housing having an air inlet, a first panel duct leading from the housing to a first panel vent, and a second panel duct leading from the housing to a second panel vent, the first and second panel vents being disposed between the first and second panel ducts and an interior of a passenger compartment;
• a first panel duct door disposed to selectively open and close the first panel duct;
• a second panel duct door disposed to selectively open and close the second panel duct;
• at least one air blower drawing air into the air duct housing via the air inlet and conveying the air toward the first and second panel ducts, the first panel duct door being disposed between the first panel vent and the at least one air blower such that air flowing out of the first panel vent into the interior of a passenger compartment must first pass by the first panel duct door, and the second panel duct door being disposed between the second panel vent and the at least one air blower such that air flowing out of the second panel vent into the interior of a passenger compartment must first pass by the second panel duct door;
• and
• a first panel actuation assembly operatively coupled to the first and second panel duct doors to simultaneously control positions of the first and second panel duct doors in response to operation of the user input interface between a plurality of settings,
• the positions of the first and second panel duct doors including at least one setting in which different airflow volumes are passed by the first and second panel duct doors,
• the first panel actuation assembly including a first control link, a second control link non rotatably attached to the first control link, and a first actuator operatively coupled to the first and second control links to rotationally move the first and second control links,
• the first duct door being rotationally mounted relative to the first control link, and the first duct door including a first positioning arm cooperating with the first control link to position the first duct door in different positions in response to rotation of the first control link;
• the second duct door being rotationally mounted relative to the second control link, and the second duct door including a second positioning arm cooperating with the second control link to position the second duct door in different positions in response to rotation of the second control link,
• the first and second duct doors being rotationally supported by a first shaft attached to the first and second control links, and
• the first and second panel duct doors being rotatable about a common axis.
