ABSTRACT:
An air-guiding appliance (10) for the directionally defined introduction (R) of air (L) supplied on the rear side (20) of the appliance into a space (22), in particular interior of a vehicle, having a housing (26), at least one duct (24) in which the air (L) is supplied to the housing (26), an air-guiding device (12) which has recesses (14) on the front side and by means of which the direction (R) of the air flowing out into the space (22) can be defined, means for setting the direction (R) of the air-guiding device (12) and, if appropriate, means for setting the quantity of the air flowing into the space (22), is distinguished by the fact that a jet pipe (30) which can be displaced in and counter to the direction of the supplied air (L) is arranged in the housing (26) or in the duct (24) and its air outlet opening (28) is smaller in size than the cross-sectional surface of the air-guiding device (12), in which case, in the retracted position of the jet pipe (30), the air (L) emerges from the air-guiding device (12) with a diffused outflow profile and, in the extended position of the jet pipe (30), the air outlet opening (32) of said jet pipe is brought so close to the inside of the air-guiding device (12) that the air emerges with a focused outflow profile (42).
