Abstract: An air-guiding nozzle has a fixed slat and several parallel pivoting slats. The fixed slat is configured to supply air to a vehicle side window and the pivoting slats are configured to blow air onto a person in the interior of the vehicle. When the pivoting slats are pivoted to their full extent, several of them close the discharge region that blows air onto a person in the interior of the vehicle and at least one of the pivoting slats interacts with the fixed slat such that the discharge region which supplies air to the vehicle side window is enlarged. This allows a compact construction of the air-guiding nozzle, which makes it particularly suitable for integration into the region of the B-pillar above the door ledge of a motor vehicle.
