DETAILED DESCRIPTION

[0057] A first exemplary embodiment of air vent 1 according to the invention is described in greater detail below with reference to the representations in FIGS. 1 to 4. To be more precise, FIGS. 1 and 2 show air vent 1 according to the invention according to the first exemplary embodiment in the neutral position, while air vent 1 is shown in a maximal position in FIGS. 3 and 4.

[0058] Air vent 1 has a housing 2 with a housing main body 11. Although not represented in the drawings, it is in principle conceivable if housing main body 11 is divided into a housing lower part and a housing upper part which is detachable from the housing lower part. Air vent 1 can also have a panel which is connected or can be connected to housing 2.

[0059] Housing 2 has an air inlet region with a (single) air inlet opening and an air outlet region or outflow region 14 opposite the air inlet region. In the case of the air outlet region or outflow region 14, a total of two air outlet openings arranged on top of one another in this case are provided.

[0060] As can be inferred from the schematic sectional view, for example, according to FIG. 2, a single air duct 3 is preferably formed by housing wall 5a, 5b of housing 2 in an end region of air vent 1 which faces the air inlet region of air vent 1. To be more precise, in this exemplary embodiment, an upper housing wall 5a and a lower housing wall 5b opposite upper housing wall 5a delimit air duct 3 for air flowing from the air inlet opening along a main flow direction H.

[0061] As seen in main flow direction H, air vent 1 is divided substantially into two regions: in a first region which faces the air inlet region of air vent 1, a mechanism for horizontal air deflection of the air flowing through air duct 3 along a main flow direction H is provided. This mechanism for horizontal air deflection has at least one and preferably a plurality of vertical air-guiding slats arranged parallel to one another, which air-guiding slats are pivotable relative to housing 2 of air vent 1 about an axis of rotation extending perpendicular to main flow direction H.

[0062] The second region of air vent 1 is arranged immediately adjacent to the first region of air vent 1 and serves the purpose of vertical air deflection. An air-guiding slat 4 which is arranged substantially centrally in air duct 3 and is in the neutral position according to FIGS. 1 and 2 substantially in a horizontal plane is used for this purpose. Said air-guiding slat 4 is mounted in a pivotable manner about an axis of rotation 6 relative to housing 2.

[0063] A first sub-duct for the air flowing through air vent 1 is formed between air-guiding slat 4 and upper housing wall 5a, while a second sub-duct is formed between air-guiding slat 4 and lower housing wall 5b. In the neutral position, i.e. in the position in which air-guiding slat 4 is in its straight-ahead position in relation to main flow direction H, the two sub-ducts preferably have a substantially identical effective flow cross section.

[0064] At least one region of the housing wall of housing 2, and in particular at least one region of the upper or lower housing wall 5a, 5b, i.e. that housing wall 5a, 5b which lies in a plane extending parallel to axis of rotation 6 of air-guiding slat 4, is formed to be adaptive according to the invention.

[0065] To be more precise, in the case of the first exemplary embodiment of air vent 1 according to the invention shown in the drawings, it is provided that both upper and lower housing walls 5a, 5b of housing 2 of air vent 1 according to the invention have in each case an adaptive region 7, 8.

[0066] Each adaptive region 7, 8 is formed such that corresponding adaptive region 7, 8 is moved out and in particular pivoted out of its straight-ahead position into air duct 3, in dependence on the direction in which air-guiding slat 4 is pivoted relative to housing 2 of air vent 1 and in dependence on the degree of the deflection of air-guiding slat 4. In this manner, the air deflection of the air flowing through air vent 1 can where necessary be improved.

[0067] As can be inferred from the representation in FIG. 2, both adaptive regions 7, 8 of upper and lower housing wall 5a, 5b are formed in each case in a region of corresponding housing wall 5a, 5b downstream of a virtual line extending orthogonally to main flow direction H. This virtual line extends parallel to axis of rotation 6 of air-guiding slat 4 and is oriented in particular orthogonally in relation to main flow direction H.

[0068] Although this should not be regarded as a restriction, it is provided in the case of the exemplary embodiments of air vent 1 according to the invention that respective adaptive regions 7, 8 of the housing walls are formed in each case as air-guiding element 9, 10 or have in each case an air-guiding element 9, 10 which have in each case a dimension extending perpendicular to main flow direction H which corresponds at least substantially to the dimension of air-guiding slat 4 extending perpendicular to main flow direction H.

[0069] On the other hand, adaptive regions 7, 8 designed in the form of air-guiding elements 9, 10 can be arranged on a main body 11 of housing 2 of air vent 1 or integrated in a main body 11 of housing 2 of air vent 1 and are able to be pivoted relative to main body 11 of housing 2 about an axis of rotation extending substantially perpendicular to main flow direction H.

[0070] As can be inferred in particular from the sectional representations according to FIG. 2 and FIG. 4, adaptive regions 7, 8, designed in each case in the form of air-guiding elements 9, 10, of housing walls 5a, 5b are arranged, at least partially and/or regionally, in corresponding groove-shaped regions 12, which extend perpendicular to main flow direction H and are formed in main body 11 of housing 2. Air-guiding elements 9, 10, which form adaptive region 7, 8 of housing wall 5a, 5b, are able to be pivoted, at least partially, from corresponding groove-shaped region 12 into the air flowing through air duct 3. In the illustrated embodiment, the groove-shaped regions 12 are formed by each housing wall 5a, 5b progressively thickening beginning at a location upstream, in the main flow direction H, from the groove-shaped region, and then having a stepwise decrease in thickness to create the groove-shaped region, where the increase in wall thickness is achieved at the internal duct facing sides of the housing walls 5a, 5b. Thus, a gap or spacing between the duct facing sides of the housing walls 5a, 5b is greater in the groove-shaped regions 12 than such gap or spacing is immediately upstream of the groove-shaped regions. However, other configurations to form the groove-shaped regions 12 are possible.

[0071] It can furthermore be inferred from the sectional views according to FIG. 2 and FIG. 4 that, in the case of the first exemplary embodiment of air vent 1 according to the invention, each air-guiding element 9, 10 which serves as an adaptive region of housing wall 5a, 5b has a surface which points in the direction of air duct 3 and which is, at least partially or regionally, of concave form and is embodied in particular in a complementary manner to a region of the surface of air-guiding slat 4 pointing in the direction of corresponding air-guiding element 9, 10.

[0072] A comparison of the sectional views in FIGS. 2 and 4 shows that the two adaptive regions 7, 8, designed in each case as air-guiding elements 9, 10, of housing wall 5a, 5b are pivotable in each case about an axis of rotation extending substantially perpendicular to main flow direction H relative to housing main body 11 on one hand and relative to air-guiding slat 4 on the other hand. The respective axes of rotation of the two air-guiding elements 9, 10 can (but do not have to) match one another, i.e. a joint axis of rotation can be present for both air-guiding elements 9, 10.

[0073] Although not shown explicitly in the drawings, it is advantageous if a motor-actuable, in particular electric motor-actuable, or manually actuable actuation mechanism is assigned to air-guiding slat 4 of air vent 1 according to the invention in order where necessary to be able to pivot air-guiding slat 4 relative to housing wall 5a, 5b of air vent 1.

[0074] It is provided in particular here that the two adaptive regions 7, 8, designed in each case in the form of an air-guiding element 9, 10, of housing wall 5a, 5b are operatively coupled to air-guiding slat 4 or to the actuation mechanism assigned to air-guiding slat 4 such that, when air-guiding slat 4 is pivoted relative to housing 2, air-guiding elements 9, 10, which serve as adaptive regions 7, 8 of housing wall 5a, 5b, are pivoted about their axes of rotation.

[0075] In the case of the first exemplary embodiment of air vent 1 according to the invention according to FIGS. 1 to 4, it is provided that the two adaptive regions 7, 8, designed in each case as air-guiding element 9, 10, of housing wall 5a, 5b are opposite one another, wherein air-guiding slat 4 is arranged, at least regionally, between the two air-guiding elements 9, 10.

[0076] The operative coupling between air-guiding elements 9, 10 on one hand and air-guiding slat 4 or the actuation mechanism assigned to air-guiding slat 4 on the other hand is preferably selected such that, in a state in which air-guiding slat 4 is, with respect to main flow direction H, in its straight-ahead position (cg. FIG. 1 and FIG. 2), a first sub-duct is formed between lower (first) air-guiding element 9, 10 and air-guiding slat 4 and a second sub-duct is formed between upper (second) air-guiding element 9, 10 and air-guiding slat 4.

[0077] On the other hand, the operative coupling between air-guiding elements 9, 10 on one hand and air-guiding slat 4 on the other hand is selected such that, in a state in which the air-guiding slat 4 is, about its axis of rotation 6, pivoted relative to housing 2 of air vent 1 in the direction of first air-guiding element 4, the effective flow cross section of the first sub-duct is reduced in comparison with the effective flow cross section of the first sub-duct in the neutral position of air vent 1, while the effective flow cross section of the second sub-duct remains, at least substantially, unchanged.

[0078] It can furthermore be inferred from the representation in FIGS. 3 and 4 that, in the maximal position of air vent 1, i.e. in a state in which air-guiding slat 4 is, about its axis of rotation 6, pivoted relative to housing 2 to a maximum extent in the direction of first (or second) air-guiding element 9, 10, the first (or second) sub-duct is blocked by first (or second) air-guiding element 9, 10, wherein the effective flow cross section of the other sub-duct is at least substantially unchanged in comparison with the state in which air-guiding slat 4 is in its straight-ahead position.

[0079] In the case of the first exemplary embodiment of air vent 1 according to the invention, the vertical air deflection is brought about by the use of two pivotable air-guiding element 9, 10 on the front upper and lower edge, on the inside of housing 2 as well as horizontal air-guiding slat 4 inside housing 2. Horizontal air-guiding slat 4 located inside moves up and down with outer pivotable air-guiding elements 9, 10—depending on the desired deflection. Air-guiding elements 9, 10 are controlled in their movement which is dependent on horizontal air-guiding slat 4 such that they are located in each case in the ideal position for air deflection.

[0080] If horizontal air-guiding slat 4 is moved into the upper maximal position in order to deflect the air maximally upward, upper air-guiding element 9, 10 retracts into housing 2 or into housing main body 11 of housing 2 and thus releases the maximal cross section. Horizontal air-guiding slat 4 comes to almost bear against upper air-guiding element 9, 10 and thus shuts off the air throughflow above air-guiding slat 4.

[0081] At the same time, lower air-guiding element 9, 10 in its maximal position moves upward and thus forms a bulge at the bottom of housing 2. Together with preferably inclined air-guiding slat 4, a narrow air duct is thus formed which directs the air flow upward.

[0082] For downward air deflection, horizontal air-guiding slat 4 is correspondingly moved downward. Both air-guiding elements 9, 10 follow this movement. Lower air-guiding element 9, 10 retracts and upper air-guiding element 9, 10 extends to its maximal position. As a result, a bulge is again generated on housing 2. As a result of this, a narrow air duct is formed, the air flow of which is directed downward. Air-guiding slat 4 almost comes to bear against upper air-guiding element 9, 10 and thus blocks the air flow below air-guiding slat 4.

[0083] The invention is of course not restricted to a horizontal installation situation; on the contrary, a vertical installation situation or an installation situation between horizontal and vertical is also conceivable.

[0084] According to embodiments, it is advantageous if deflections between, for example, 35° and 40° (top/bottom) are achieved.

[0085] In order to operatively couple air-guiding slat 4 to air-guiding elements 9, 10, it is conceivable if air-guiding slat 4 sits on an axis of rotation 6 which is controlled, for example, via an operating wheel and is pivoted in this manner. There sits, for example, on air-guiding slat 4 an operating knob with which the corresponding deflection in the horizontal direction (right/left), which is controlled, for example, via rear, vertically oriented air-guiding slat pack 13, is carried out.

[0086] In a further embodiment, an air-guiding slat 4 which is visible from the outside can be dispensed with. Air-guiding slat 4 required for air guiding is positioned further upstream in housing 2, for example, behind the vertically oriented air-guiding slat pack for the right/left deflection. Such a system naturally has advantages in the case of the right/left deflection since the elements responsible for this can be placed further to the front in housing 2.

[0087] In this context, reference is made to the second exemplary embodiment of air vent 1 according to the invention which is shown schematically in FIGS. 5 to 8.

[0088] As also in the case of the first exemplary embodiment described above of air vent 1 according to the invention, air vent 1 according to the invention according to the second exemplary embodiment has a first air-guiding element 9, 10, designed in the form of an adaptive region of housing wall 5a, 5b, as well as a second air-guiding element 9, 10, also designed in the form of an adaptive region of housing wall 5a, 5b, wherein these two air-guiding elements 9, 10 are opposite one another.

[0089] In contrast to the first exemplary embodiment of air vent 1 according to the invention, in the case of the second exemplary embodiment, air-guiding elements 9, 10 which serve as an adaptive region of housing wall 5a, 5b are arranged downstream of air-guiding slat 4.

[0090] Air-guiding slat 4 required for the air guidance is positioned further upstream (i.e. behind) in housing 2. As indicated in FIG. 6 or FIG. 8, a slat pack 13 with further air-guiding slats can be provided between air-guiding slat 4, which in the example shown serves the purpose of vertical air deflection, wherein these further air-guiding slats are oriented perpendicular to air-guiding slat 4 for the vertical air deflection and serve the purpose of horizontal deflection of the air flow flowing through air vent 1.

[0091] Such a system has advantages in the case of horizontal air deflection since the elements responsible for this can be placed further to the front in housing 2, i.e. closer to outflow region 14 of air vent 1.

[0092] As also in the case of the first exemplary embodiment, in the case of the second exemplary embodiment of air vent 1 according to the invention, it is provided that air-guiding slat 4 can be manipulated for vertical air deflection via a corresponding actuation mechanism. It is furthermore provided that air-guiding elements 9, 10 are operatively coupled to air-guiding slat 4 or to the correspondingly assigned actuation mechanism so that air-guiding elements 9, 10 are correspondingly automatically adjusted with air-guiding slat 4.

[0093] A comparison of the sectional views according to FIG. 6 and according to FIG. 8 shows that the operative coupling between air-guiding elements 9, 10 on one hand and air-guiding slat 4 or the correspondingly assigned actuation mechanism on the other hand is preferably selected such that, in a state in which air-guiding slat 4 is in its straight-ahead position (cf. FIG. 5 and FIG. 6), a first (upper) sub-duct and a second (lower) sub-duct extending parallel hereto are formed between air-guiding slat 4 and housing 2.

[0094] If, however, air-guiding slat 4 is pivoted about its axis of rotation 6 relative to housing 2 in the direction of that housing wall 5a in which first air-guiding element 9 designed as an adaptive region is provided, the effective flow cross section of the second sub-duct is reduced in comparison with the effective flow cross section of the second sub-duct in the straight-ahead position of air-guiding slat 4 by air-guiding slat 4, wherein at the same time first air-guiding element 9 is pivoted into air duct 3 in order in this manner to bring about a deflection of the air flow.

[0095] In detail, in the case of the second exemplary embodiment of air vent 1 according to the invention, it is provided that axis of rotation 6 of air-guiding slat 4 extends through a downstream region of air-guiding slat 4. The second sub-duct is preferably entirely blocked by air-guiding slat 4 if air-guiding slat 4 is in a state in which it is pivoted about its axis of rotation 6 relative to housing 2 to a maximum extent in the direction of that housing wall 5a in which first air-guiding element 9 designed as an adaptive region is provided.

[0096] In other words, if horizontal air-guiding slat 4 which lies further to the rear is moved into the upper maximal position (cf. FIG. 7 and FIG. 8) in order to deflect the air maximally upward, upper air-guiding element 9 retracts into housing 2 or into main body 11 of housing 2 of air vent 1 and thus releases the maximal cross section. Vertical air-guiding slat 4 shuts off the air throughflow above air-guiding slat 4 and steers the air flow onto the underside of housing 2. At the same time, lower air-guiding element 10 in its maximal position moves upward and thus forms the bulge on housing 2 which directs the air flow upward.

[0097] For downward air deflection, horizontal air-guiding slat 4 is correspondingly moved downward. Here, the air flow on the underside of air-guiding slat 4 is shut off and deflected to the upper side of housing 2. Both air-guiding elements 9, 10 arranged downstream follow the movement of air-guiding slat 4.

[0098] Lower air-guiding element 10 retracts into housing 2 or into main body 11 of housing 2 of air vent 1 and upper air-guiding element 9 extends to its maximal position. As a result of this, a bulge on the upper side of housing 2 is formed which thus directs the air flow downward.

[0099] The kinematics for control of air-guiding elements 9, 10 via the movement of air-guiding slat 4 can in principle be performed, for example, via coupling rods. The advantage here is that sliding block guides, which tend to jam, can be avoided.

[0100] Control via sliding block guides is nevertheless of course conceivable. Transmission arrangements with gear wheels are furthermore also conceivable.

[0101] Motor-driven controls for horizontal air-guiding slat 4 and air-guiding elements 9, 10 are also possible.

[0102] In further embodiments, combinations of these above-mentioned principles cannot be ruled out. Housing 2 of air vent 1 is advantageously—as seen in cross section—embodied to be rectangular or at least substantially rectangular, wherein preferably all opposite housing walls extend at least substantially parallel in particular over the entire length of housing 2.

[0103] It is furthermore conceivable to arrange several air vents 1 on top of one another.

[0104] The solution according to the invention makes it possible to construct air vents 1 in the case of which the distance between two opposite housing walls (in particular of upper and lower housing wall 5a, 5b) above all in the outflow region of air vent 1 is at most 60 mm, preferably at most 30 mm and more preferably at most 20 mm.

[0105] The invention furthermore relates to a venting system for a vehicle, wherein this venting system has at least one air vent 1 of the type according to the invention.
