Air distributing device for an air conditioning unit of a motor vehicle

An air distributing device for an air conditioning unit of a motor vehicle, the device configured to distribute air to rear seats of a cabin of the motor vehicle, the device comprising:

• a housing defining an air intake chamber, on the housing there being formed an air inlet by means of which the air intake chamber may be supplied with an air flow, a central air outlet located in front of the air inlet, and two side air outlets arranged on opposing sides of the housing, and
• a drum flap for distributing the air flow to the air outlets;
• wherein the drum flap is rotatably mounted about an axis orthogonal to a direction running from the air inlet to the central air outlet to control a distribution of the air flow to the central air outlet and to the side air outlets, the drum flap comprising two flat side flap portions parallel to each other, and a circular arch-shaped central flap portion interconnecting the two side flap portions, and
• wherein the drum flap is movable between a first position, in which the air inlet is closed by the central flap portion of the drum flap;
• a second position, in which the two side air outlets are closed by the drum flap, the air intake chamber is entirely in fluid communication with the air inlet and with the central air outlet, and an air flow between the air inlet and the central air outlet is allowed;
• and a third position, in which the central air outlet is closed by the central flap portion of the drum flap, the air intake chamber is entirely in fluid communication with the air inlet and the side air outlets, and an air flow between the air inlet and the side air outlets is allowed.
