Abstract

An air discharger for discharging an air stream, in particular in a vehicle interior, includes at least one air guide channel and at least one air routing element disposed therein. The routing element being designed as a vane wheel having at least one vane, wherein each of the vanes is formed from at least two segments disposed in succession axially. The segments being able to move at least relative to one another angularly between a position that brings about a “diffuse” mode and a position that brings about a “total air” mode by way of an axially adjustable variable flow cross section of the air guide channel.

First claim

What is claimed is:

1. An air outlet for discharging an air stream in a vehicle interior, the air outlet comprising:
a housing;
at least one air guide channel within the housing;
at least one air guide element disposed in the air guide channel, the air guide element configured as a vane wheel having at least one vane, wherein each vane is formed from at least two axially successively disposed segments that are movable angularly relative to one another between a position that brings about a diffuse mode and a position that brings about a total air mode with an axially variably adjustable flow cross section of the air guide channel, each of the axially successively disposed segments comprising:
an inner ring;
a recess formed in the inner ring; and
a pin formed adjacent the recess, the pin configured to engage the recess of an adjacent one of the axially successively disposed segments;

a segment housing surrounding the segments, the segment housing having a plurality of outwardly projecting guide ribs;
guide beads disposed on an inside surface of the housing, the guide beads configured to receive the guide ribs; and
an actuating element to move the segments relatively to one another,
wherein the actuating element comprises an adjusting ring placed centrally on an axially last of the segments, said adjusting ring having a gripping structure disposed around an outer edge of the adjusting ring, the adjusting ring projecting outwardly from the housing, and a plurality of adjusting bars disposed within the adjusting ring, the gripping structure comprising a plurality of gripping surfaces positioned outside of the housing and configured to be gripped by a user for activating the actuating element.

2. The air outlet according to claim 1 , further comprising at least one angular staggering positioning device, which in at least one part of the positions of the air guide element brings about a defined angular stagger of individual axially successively disposed segments.

3. The air outlet according to claim 2 , wherein the individual axially successively disposed segments of at least one vane are disposed along a nonlinear curve, along an arcuately curved line, or along a spline line.

4. The air outlet according to claim 1 , wherein an entrance angle of at least one vane is at least at times between 30° and 150°, between 70° and 110°, or between 85° and 95°, and/or the exit angle of the air stream is at least at times between 0° and 90°, between 10° and 70°, or between 20° and 40°.

5. The air outlet according to claim 1 , wherein an average stagger angle, at least at times between two axially successively disposed segments, is between 0° and 90°, between 40° and 80°, or between 50° and 70°.

6. The air outlet according to claim 1 , wherein at least two of the axially successively disposed segments have a different shape or wherein all of the axially successively disposed segments have a different shape.

7. The air outlet according to claim 1 , wherein, in the diffuse mode, a substantially flush surface contouring of at least one vane results, which runs approximately parallel to a curve of the segments of a corresponding vane.

8. The air outlet according to claim 1 , wherein at least two segments disposed axially adjacent in succession overlap at least in areas when viewed in an axial direction.

9. The air outlet according to claim 1 , further comprising at least one additional air guide channel that is operated substantially steadily in a total air mode.

10. The air outlet according to claim 1 , wherein at least one of the air guide channels is configured as a ring-shaped air guide channel and/or as a circular air guide channel.

11. The air outlet according to claim 1 , wherein at least one segment has a sleeve-like extension, which functions as a bearing bushing for at least one part of the other segments.

12. The air outlet according to claim 1 , further comprising at least one self-locking device for at least one segment, which is formed as a narrow fit, as frictional material, as an insertion device, and/or as a roughening.

13. The air outlet according to claim 1 , further comprising at least one driver device, which imparts a movement between at least two of the axially successively disposed segments.

14. The air outlet according to claim 1 , wherein the segments follow a predefined edge contouring, an air guide channel contouring, or a housing contouring.

15. The air outlet according to claim 1 , wherein the at least two axially successively disposed segments comprise a disk element having the inner ring element, an outer ring element disposed concentrically around the inner ring element, and at least two ribs radially disposed between the inner ring element and the outer ring element.

16. The air outlet according to claim 15 , further comprising a stop formed on the at least two ribs.

17. The air outlet according to claim 1 , further comprising an elongate hollow cylinder disposed in said at least one air guide channel,
wherein said inner ring of each of the axially successively disposed segments is disposed around the elongate hollow cylinder.

18. The air outlet according to claim 1 , wherein said pin is smaller than said recess such that said pin is configured to move within said recess.

19. The air outlet according to claim 1 , wherein each of the axially successively disposed segments is axially rotatable.

20. An air outlet, the air outlet comprising:
a housing;
an air guide channel within the housing;
an air guide element disposed in the air guide channel, the air guide element having a vane, wherein the vane is formed from at least two axially successively disposed segments, each of the successively disposed segments being movable angularly relative to one another, each of the axially successively disposed segments comprising:
an inner ring;
a recess formed in the inner ring; and
a pin formed adjacent the recess, the pin configured to engage the recess of an adjacent one of the axially successively disposed segments;

a segment housing surrounding the segments, the segment housing having a plurality of outwardly projecting guide ribs; and
guide beads disposed on an inside surface of the housing, the guide beads configured to receive the guide ribs; and
an actuating element to move the segments relatively to one another,
wherein the actuating element comprises an adjusting ring placed centrally on an axially last of the segments, said adjusting ring having a gripping structure disposed around an outer edge of the adjusting ring, the adjusting ring projecting outwardly from the housing, and a plurality of adjusting bars disposed within the adjusting ring, the gripping structure comprising a plurality of gripping surfaces positioned outside of the housing and configured to be gripped by a user for activating the actuating element.

21. An air outlet, the air outlet comprising:
a housing, said housing comprising a guide portion disposed on an inner surface of said housing;
an air guide channel disposed within said housing; and
an air guide element disposed in said air guide channel, said air guide element comprising:
a segment housing, said segment housing comprising at least two outwardly projecting ribs disposed on an outer surface of said segment housing, said at least two outwardly projecting ribs being configured to be received within said guide portion;
at least two axially successively disposed segments mounted within said segment housing concentrically around a longitud
