For air-conditioning within a vehicle interior of a motor vehicle, an air vent is provided with at least one air-directing device located in the region of an air outlet opening. The air vent is configured to allow air flowing out of the air outlet opening to flow, by way of the Coanda effect, in a directed manner along a surface which is adjacent to the air outlet opening. The air-directing device and the adjacent surface are inclined in relation to each other by an angle of inclination which is between 23&#xb0; and 27&#xb0;, and the directed air has a volumetric flow of between 30 m/h and 700 m/h.

Air vent for a motor vehicle

An air vent is provided for directly introducing air into a passenger compartment of a vehicle. The air vent has at least one outlet opening and at least one deflecting surface which is arranged in the region of the outlet opening, which runs radially outwards with respect to a flow direction of the air flowing in the direction of the deflecting surface, and by which the air flowing in the direction of the deflecting surface can be deflected radially outwards using the Coanda affect. An intuitively controllable and inexpensively producible air vent is achieved in that the shape and arrangement of the deflecting surface is adapted to a flow speed of the air flowing in the direction of the deflecting surface such that it is equally probable that the air flowing in the direction of the deflecting surface is deflected radially outwards by the deflecting surface or it is not.
