Abstract
Improved air-conditioning of the rear-seat area of a motor vehicle is achieved substantially independently from the front-seat area in a heating or air-conditioning system having means for controlling the temperature of the supply air via a front-seat control unit by employing a front air flap with a cool air passage at the inlet of a heat exchanger. A front-seat air-mix chamber is connected with a rear-seat air-mix chamber having a rear-seat area duct, a rear-seat foot duct, and a rear-seat air-mix flap with a cool air passage therethrough to control the proportion of cool and warm air entering the ducts. Cool air is provided from the inlet side of a heat exchanger flowing through the cool air passage in the front air flap and the cool air passage in the rear-seat air-mix flap while warm air is provided from the outlet of the heat exchanger. The rear-seat air-mix flap is actuated either jointly with a front-seat air-mix flap in a front-seat air-mix chamber by a temperature-setting element on the front-seat control unit or by a separate rear-seat control unit.
