A heating or air-conditioning system for a vehicle has a cold-air duct and a warm-air duct which open out into an air-mixing chamber. One control member is assigned to each of the cold-air duct and the warm-air duct for setting the amount of cold or warm air which flows into the air-mixing chamber. The control member for the amount of warm air is designed as a shutter which includes a plurality of closure lamellae which are arranged next to one another, which overlap one another in the closed position, and which can be pivoted by a common actuating drive. To achieve a less progressive, substantially linear control curve of the shutter in the lower pivoting range, the shutter is designed in such a way that the individual closure lamellae, when they pivot out of their closed positions, open up unevenly sized opening cross sections for the warm air to pass through.

Heater or air conditioner for vehicles

A ventilation device for an interior of a vehicle provided with a windshield and instrument panel has a plurality of air outlet openings provided side by side in the instrument panel close to the windshield in two rows, one behind the other as viewed in the travel direction. To ensure freedom from precipitation on a large windshield without adversely affecting climate comfort in the interior, each row of air outlet openings is connected to one of two separate supply channels and the air supply channel that leads to the front row receives warm air conditioned to a higher temperature than the air supply channel that leads to the back row.
