Abstract
The present invention relates to a heating and/or air conditioning system for vehicle interiors with air outlets located at the middle level of the vehicle interior, especially in a dashboard. The outlets include a middle nozzle connected by air ducts with an air distributor, the middle nozzle having a middle nozzle automatic button, with a mixing chamber integrated into the air distributor. The chamber has a cold air duct controlled by a cold air flap for supplying cold air to the mixing chamber and at least one outlet opening to the middle level, with the air to the middle level being controllable by at least one middle level flap, with an automatic control device that comprises an additional automatic button, and with a control device for linking signal values of the adjusting elements and programmed control of adjusting motors to set the air flaps. Provision is made for the cold air flap and the (at least one) middle level flap to be coupled together in terms of their movement possibilities by forced guidance so that, for maximum heating, the cold air flap and the middle level flap are closed, to regulate the air volume to the middle level, the cold air flap is closed and the middle level flap is open to correspond to the desired air flow, and to lower the temperature in the middle level, the middle nozzle automatic button is unlocked and the cold air flap is opened by turning an operating element.
