In 1 is a motor vehicle according to the invention 1 symbolically shown in longitudinal section view, in the motor vehicle interior 5 an inventive air vent 10 located. The air vent 10 can in a conventional manner to an instrument panel, not shown here, a Center console, an interior trim, a headliner or the like. others in the vehicle interior 5 be mounted components.

On his in the 1 right side is the air vent 10 with an entrance opening 15 to an air inlet duct 20 connected, through which an input air flow I can flow. The inlet airflow I may comprise air-conditioned or uncontrolled air supplied by an air conditioner or HVAC device, not shown here, and / or a blower not shown in the direction of the air vent 10 is transported. It should be noted that in the embodiment shown here only one inlet opening 15 is provided. However, it is also possible to have more than one entrance opening 15 provide one or more input air streams I in the air vent 10 to transport.

In order that the input air flow I is able to flow in the direction of a desired virtual focal point F, are in the air vent 10 a first disc 25 and a second disc adjacent thereto 30 intended. The first disc 25 according to the embodiment shown here a number of radially spaced apart and over the circumference of the first disc 25 distributed inlets 40 on, as with reference to 2A will be carried out further. The second disc 30 in turn has a first outlet opening 45 , a second outlet 50 (This is beyond the paper level of the 1 ), a third exit opening 55 (This is located on this side of the paper plane of the 1 ) and a fourth outlet opening 60 on, which are radially spaced from each other and over the circumference of the second disc 30 are distributed as with reference to 2 B will be carried out further.

In the in 1 shown operating position are the first disc 25 and the second disc 30 so arranged pivoted about the common axis of rotation L, that the inlet openings 40 with the respective outlet openings 45 . 50 . 55 respectively. 60 are fully aligned. In this case, flows through a part of the input air flow I the exit opening 45 and leaves the vent 10 as a first free jet II , Another part of the inlet air flow I flows through the outlet opening 50 and leaves the vent 10 as a second free jet III (which begins beyond the paper plane). Another part of the intake airflow I flows through the outlet opening 55 and leaves the vent 10 as a third free jet IV (which starts on this side of the paper plane). A final part of the intake airflow I finally flows through the outlet opening 60 and leaves the vent 10 as a fourth free jet V , The four free-rays II . III . IV and V unite in the focal point F.

It should be noted that on the housing 35 a the first disc 25 axially securing the first housing cover (not shown) and / or a second disc 30 axially securable second housing cover (not shown) may be provided.

The orthogonally oriented to the rotation axis L first disc 25 is in 2A shown again in more detail in plan view. Starting from a middle section 65 are concentric about the axis of rotation L around a first ring 70 (the radially outermost ring), a second ring 75 , a third ring 80 and a fourth ring 85 (The radially on the innermost ring) each spaced from each other. The middle section 65 as well as the four rings 70 . 75 . 80 and 85 are through eleven beyond the circumference of the first disc 25 evenly distributed webs 90 interconnected, wherein between said elements in the 2A be formed substantially arcuate surface areas. At discrete, white marked locations, the surface areas correspond to the inlet openings 40 ; at the other, hatched areas, the areas are fluid-tight, so that no input air II can flow through them. The geometric center of gravity of such surface areas extending between the first ring 70 and the second ring 75 each has a first radial distance R1 from the axis of rotation L. The geometric center of gravity of such surface areas extending between the second ring 75 and the third ring 80 each has a second radial distance R2 from the axis of rotation L. The geometric center of gravity of such surface areas extending between the third ring 80 and the fourth ring 85 each has a third radial distance R3 from the axis of rotation L. The geometric center of gravity of such surface areas finally, extending between the fourth ring 85 and the middle section 65 each has a fourth radial distance R4 from the rotation axis L.

It is easy to see that the position and geometry of the surface areas depends on the number and arrangement of the rings 70 . 75 . 80 and 85 and footbridges 90 depends. As a result, it is possible in particular, the cross-sectional area of the between the central portion 65 and the fourth ring 85 located inlet openings 40 to increase by the distance between the two is increased from each other. For example, if it is desired, the cross-sectional areas of the between the first ring 70 and the second ring 75 located inlet openings 40 To reduce, so only the distance between the two has to be reduced become. In addition, the webs can 90 - Not shown here - in a non-uniform arrangement over the circumference of the first disc 25 be distributed, which further design options in terms of number, position and geometry of the inlet openings 40 opened. Overall, it is thus possible in an advantageous manner, the position and geometry of the cross-sectional areas of the outlet openings 45 . 50 . 55 and 60 swept inlets 40 arbitrarily, in particular the same size, to train.

The second disc 30 is in 2 B shown again in more detail in plan view. On the axis of rotation L orthogonal aligned second disc 25 are the ones out 1 already known passages 45 . 50 . 55 and 60 radially and over the circumference of the second disc 25 arranged distributed. In this case, the geometric center of gravity of the first outlet opening 45 the first radial distance described above R1 from the rotation axis L on. The geometric center of gravity of the second exit opening 50 has the above-described second radial distance R2 from the rotation axis L on. The geometric center of gravity of the third exit opening 55 has the previously described third radial distance R3 from the rotation axis L on. The geometric center of gravity of the fourth exit opening 60 finally, has the fourth radial distance described above R4 from the rotation axis L on.

The position, geometry and size of the first opening 45 essentially corresponds to the position, the geometry and the size of an area between the first ring 70 , the second ring 75 and two adjacent webs 90 is trained. The position, geometry and size of the second passage opening 50 essentially corresponds to the position, the geometry and the size of a surface area between the third second ring 75 , the third ring 80 and two adjacent webs 90 is trained. The position, geometry and size of the opening 60 essentially corresponds to the position, the geometry and the size of a surface area between the third ring 80 , the fourth ring 85 and two adjacent webs 90 is trained. The position, geometry and size of the opening 60 Finally, it essentially corresponds to the position, the geometry and the size of a surface area between the middle section 65 , the fourth ring 85 and two adjacent webs 90 is trained.

Finally, the respective geometric centers of gravity of the passage openings 45 . 50 . 55 and 60 Radially spaced substantially equal to each other or with a substantially same angle of rotation. It should be noted, however, that the latter need not necessarily be the case; Rather, the outlet openings 45 . 50 . 55 and 60 be arranged in a different relationship to each other. Because the position and geometry of the outlet openings 45 . 50 . 55 and 60 in the second disc 30 the position and geometry of the swept areas of the first pane 25 It is easy to see that the in 2 B shown outlet openings 45 . 50 . 55 and 60 can also be designed differently.

Would be the in 2 B shown second disc 30 in her shown position on the in the 2A shown first disc 25 in their position shown (hereinafter referred to as "first example constellation"), wherein the respective axes of rotation L are identical to each other, so would the outlet opening 45 over a first surface area 95 , the exit opening 50 over a second area 100 , the exit opening 60 over a third area 105 and the exit opening 55 over a fourth area 110 are located. As can be seen from the hatching or non-hatching of the surface areas in question, this would result in an air flow, not shown here, out of the outlet opening 45 can escape while the outlet openings 50 . 55 and 60 would be blocked for an air flow or would not be charged with air.

Upon rotation of the second disc 30 about the axis of rotation L by 1 / 11x360 ° clockwise (hereinafter referred to as "second example constellation") would the outlet opening 45 the next adjacent surface area 115 cover. In this case, air could pass through the outlet 50 leak out while the outlet openings 45 . 55 and 60 would be blocked or would not be exposed to air due to the formation of each adjacent next, hatched areas shown for an air flow.

It is easy to see that the conditions just described would continue to change by 1/11 × 360 ° with each continued rotation. To simplify the presentation of this fact, these are summarized in the following table, the theoretically possible and practically useful combinations: Outlet opening (reference number) combinations 45 1 0 0 0 1 1 0 0 1 1 1 50 0 1 0 0 0 0 1 1 1 1 1 55 0 0 1 0 1 0 1 0 1 0 1 60 0 0 0 1 0 1 0 1 0 1 1 wherein the numeral "1" the presence or an investment of one of the outlet openings 45 . 50 . 55 respectively. 60 with an entrance opening 40 (ie a flow) or the number "0" the absence of an inlet opening 40 (ie no flow) symbolizes. According to this convention, the first combination of the first example constellation and the second combination of the second example constellation.

As the table can be seen, no combination is provided in the event that all the outlet openings 45 . 50 . 55 and 60 closed (ie "0"), since this case also by a non-operation of the in the motor vehicle 1 in itself existing air conditioning or ventilation device (not shown) can be covered. However, if a flow through all the inlet openings 45 . 50 . 55 and 60 be prevented when operating the air conditioning or ventilation device, one of the combinations listed in the table can be replaced by a combination in which all the inlet openings 45 . 50 . 55 and 60 closed (ie "0") are. Alternatively, the middle section 65 as well as the four rings 70 . 75 . 80 and 85 instead of eleven by twelve across the circumference of the first disk 25 evenly distributed webs 90 be advantageously connected to each other in such a way that in the twelfth combination all outlet openings 45 . 50 . 55 and 60 are locked. Advantageously, two or more air vents connected in parallel to an air-conditioning or ventilation device can thereby be provided 1 operated independently of each other.

It is understood that the order of the individual combinations found in the table by a suitable arrangement of outlet openings 40 or closed surface area can be changed without the functionality of Luftausströmers invention 10 to question.

While the in 2A and 2 B illustrated embodiment of the second disc 30 four outlet openings 45 . 50 . 55 and 60 is in the 3A and 3B an alternative embodiment shown in which on the axis of rotation L closest to the outlet opening 55 the second disc 30 , and as a result on the free jet V, was waived. Furthermore, those on the between the middle section 65 the first disc of the in 2A shown embodiment and the fourth ring 85 located surface areas or inlet openings 40 omitted. Instead, in the embodiment according to 3A a middle section 65 provided whose radius is the outer radius of the fourth ring 85 equivalent.

Would be the in 3B shown second disc 30 in her shown position on the in the 3A shown first disc 25 in their position shown (hereinafter referred to as "third example constellation"), wherein the respective axes of rotation L are identical to each other, so would the outlet opening 45 over a first surface area 95 , the exit opening 50 over a second area 100 and the exit opening 60 over a third area 105 are located. As can be seen by the hatching or non-hatching of the surface areas in question, would thus not shown here first free jet II , second free jet III and third free jet IV from the outlet openings 45 . 50 respectively. 60 can escape.

Upon rotation of the second disc 30 clockwise around the axis of rotation L at 1 / 7x360 ° would be the exit opening 45 the next adjacent field or area 115 cover (hereinafter called "fourth example constellation"). In this case, air could pass through the outlet 45 and - in an analogous manner - through the outlet opening 55 exit while the outlet 60 would be blocked or would not be exposed to air due to the formation of the adjacent next, hatched area shown for an air flow.

It is easy to see that the number of theoretically possible and practically useful combinations compared to those of the embodiment according to 2A and 2 B is reduced, so that now no eleven, but only seven bars 90 are required, with a spatial adjustment or distribution of the free jets II . III and IV nevertheless preserved. Here too, the ratios just described would continue to change by 1/7 × 360 "with each continued rotation, to simplify the illustration this fact, these are summarized in the table below the theoretically possible and practically meaningful combinations: Outlet opening (reference number) combination 45 1 1 1 0 0 0 0 50 1 1 0 1 1 0 0 60 1 0 0 1 0 1 0 wherein the numeral "1" the presence or an investment of one of the outlet openings 45 . 50 respectively. 60 with an entrance opening 40 (ie a flow) or the number "0" the absence of an inlet opening 40 (ie no flow) symbolizes. According to this convention, the first combination of the third example constellation and the second combination of the fourth example constellation.

It should be noted that the outlet openings previously shown 45 . 50 . 55 respectively. 60 have been described as being aligned substantially parallel to each other. However, it is also possible in an advantageous manner, one, some or all outlet openings 45 . 50 . 55 respectively. 60 not parallel to each other. So it is possible in a particularly advantageous manner, some or all outlet openings 45 . 50 . 55 respectively. 60 to align each other, so that a movement of the or the free jets II . III . IV respectively. V is supported to each other.

In the embodiments, the first slices 25 with individual rings 70 . 75 . 80 respectively. 85 and jetties 90 shown, which are formed as a single, interconnected components. However, it is also possible in an advantageous manner, some or all of the rings mentioned 70 . 75 . 80 respectively. 85 and footbridges 90 form as one-piece elements. Further, it is possible in an advantageous manner, with adjacent outlet openings 45 . 50 . 55 respectively. 60 and / or adjacent, no outlet openings 45 . 50 . 55 respectively. 60 having surface areas, on a bridge 90 and / or a ring 70 . 75 . 80 respectively. 85 to renounce. Thus, it is possible in an advantageous manner, the first disc 25 form one piece, wherein at suitable points the outlet openings 45 . 50 . 55 respectively. 60 are omitted. So it is possible in a particularly advantageous manner, the first disc 25 from one with outlet openings 45 . 50 . 55 respectively. 60 punched out sheet metal or one with outlet openings 45 . 50 . 55 respectively. 60 To produce recessed plastic by injection molding.
