Abstract
An air-distributor box for a heating/air-conditioning system of motor vehicles has a first air-outflow orifice for the connection of a lateral nozzle and a second air-outflow orifice, arranged below the first air-outflow orifice, for ventilating the foot space as well as an air flap controlling the air stream to the second air-outflow orifice. In order to avoid the lateral nozzle having to be additionally throttled by hand from outside by the driver or front-seat passenger with the air flap opened for ventilating the foot space to a sufficient extent, the first air-outflow orifice to the lateral nozzle is assigned a throttle diaphragm. The diaphragm is positively coupled to the air flap so that the throttle diaphragm throttles the orifice cross-section of the first air-outflow orifice to the maximum extent in an open position of the air flap allowing the full air stream to the second air-outflow orifice and exposes it completely in the closing position of the air flap shutting off the air stream to the second air-outflow orifice.
