Heating or air conditioning system for a motor vehicle

A climate control system for a motor vehicle having a front seat area and a back seat area comprising:

• a. a heat exchanger having an air inlet and an air outlet;
• b. a source of cool air;
• c. a first passage coupling cool air from said source to said heat exchanger inlet;
• d. a second passage from said heat exchanger outlet to the front seat area to conduct warm air;
• e. a front air flap in said first passage movable between a position where a minimum amount of air from said first passage is directed through said heat exchanger to a position where a maximum amount of air from said first passage is passed through said heat exchanger;
• f. means for setting said front air flap from the front seat;
• g. a rear-seat air-mix chamber having an air inlet and an air outlet;
• h. a third passage from said air inlet of said heat exchanger to said rear-seat air-mix chamber directing cool air thereto;
• i. a fourth passage from said outlet of said heat exchanger to said rear-seat air-mix chamber directing warm air thereto;
• j. a rear-seat air-mix flap for selecting air from said third and fourth passages to be provided to said outlet of said rear-seat air-mix chamber;
• and
• k. a fifth passage bridging said front air flap, said fifth passage comprising a cut-out in one edge of said front air flap, such that a portion of cool air is always directed to said third passage, even when said front air flap is in said minimum position.
