Abstract
The invention relates to an air nozzle for conducting air flow from an air feed shaft or a duct from a heating, ventilating or air-conditioning installation, particularly in a motor vehicle, with a housing having a connection at the back for the air feed shaft and an air outlet opening at the front. Air guide elements with blades adjustable by way of a coupling rod are present in the air outlet opening. The axles (4) of the individual blades (5) are arranged in a blade ring (2) with one lateral coupling rod (3) or two lateral coupling rods (3), wherein the middle blade (5) is constructed as a control blade and has an actuating element (6) for adjusting the blades (5). The blade ring (2) is inserted, together with the blades (5), in an annular guide (7) of the mount (1) and is coupled with an adjusting ring (8), which is rotatably mounted in the annular guide (7) and which has at its outer circumference control elements (9) for rotating the blade ring (2). A cover mask (10) with a central passage, through which the actuating element (6) for the blades (5) is accessible or from which the actuating element protrudes to be operable, is present in the opening of the adjusting ring (8).
