  • Patent number: 11180001
    Abstract: 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.
