Ventilation nozzle

The nozzle (1) has an air-guiding device (10) forming an undercut and moving into a non-undercutting position. The air-guiding device comprises a film hinge (14) and formed on a frame (7) inserted into the nozzle. The air-guiding device is pivotable out of the undercut position into the non-undercutting position and vice versa, where the nozzle holds the air-guiding device in the undercutting position. Vertical vanes (3) are held and pivotally mounted in the frame.
