Description

An air deflecting device for an air vent and an air vent with such an air deflecting device are described.

background

Air vents are used to deflect air that is provided by an air conditioner or other ventilation device. Air vents are used in particular in vehicles to bring fresh air, tempered air and / or conditioned air into the passenger compartment of a vehicle. Vehicles can be, for example, motor vehicles, such as cars, trucks or buses, trains, planes or ships. In the case of the air vent, in addition to controlling the deflection of air that is output, for example from an air conditioning system, the amount of air output can also be regulated. Air vents can be arranged, for example, in a vehicle dashboard or in the area of the A, B or C pillar or on the roof of a motor vehicle.

State of the art

Air deflection devices with first slats, second slats and a closing flap are known from the prior art, which can be controlled separately via an operating element. To do this, the control element must perform three different movements.

A disadvantage is that a lot of space is required for the control element and the components coupled to it in order to achieve the separate control. Another disadvantage is that, due to the large number of components, the known devices require additional installation space, which is often only available to a limited extent in vehicles.

Operating devices for air vents are also known from the prior art, lamellae being able to be pivoted via an operating element, for which purpose the operating element is shifted in one direction. In addition, in the event of a further displacement in the same direction, a throttle valve which is pivotably mounted parallel to the slats can be pivoted.

EP 1 752 324 B1 discloses an air nozzle with lamellae which can be pivoted via an operating wheel, the lamellae being coupled to one another via a coupling element and the coupling element being in engagement with the operating wheel, so that turning the operating wheel causes the lamellae to pivot. The control wheel has a peripheral portion with a gear-shaped contour, which is operatively connected to other components with gear contours with a flap for controlling the flow cross-section within the air nozzle. The control wheel can also be operatively connected to the flap for controlling the flow cross section within the air nozzle via a coupling rod. For both variants, it is possible for the coupling element to be operatively connected to the flap in such a way that the flap is moved into a closed position when the slats are in a diffuse position.

In the known designs, a coupling of slats with a closing device is possible, the slats as well as the closing flap being controlled via a common operating element which has to be shifted in only one direction in order to realize both movements. In these devices, the slats coupled to an operating element and the closing flap coupled to the operating element are arranged in such a way that their pivot axes run parallel to one another.

It is therefore known from the prior art to pivot a closing or throttle flap after pivoting pivotably mounted slats.

These operating devices are limited to lamellae and throttle valves which are mounted around swivel axes running parallel to each other.

With regard to the operation of differently shaped air vents, such restrictions are, however, to be regarded as disadvantageous. It also identifies EP 1 752 324 B1 Known control device has the disadvantage that there is a direct coupling between the displacement of the flap and the slats via the control wheel, so that a displacement of the slats always causes a displacement of the flap.

task

It is therefore the task of specifying a solution that enables air deflection and air volume regulation, the number of components and the installation space being reduced. In addition, an alternative solution to the designs known from the prior art is to be specified.

solution

The above-mentioned object is achieved by an air deflecting device for an air vent with an operating element, at least one slat, a flap arrangement and a housing, the at least one slat being one the first pivot axis is pivotally mounted in the housing and is coupled to the control element, the flap arrangement has a control flap and two flap vanes, the control flap and the two flap vanes being pivotally mounted in the housing about a second pivot axis running orthogonally to the first pivot axis, the control flap a first one Section and a second section, which extend opposite to the second pivot axis, wherein the first section is coupled to the operating element and the second section is mounted between the two flap wings.

The air deflection device enables air deflection via the flap wings, one of the flap wings being able to be pivoted via the control element and thus first air deflection being achieved. The at least one lamella brings about a second air deflection, with incoming air being able to be deflected in a direction running essentially orthogonally to the air deflection via the flap blades. The flap blades can also be used to throttle the amount of air supplied, so that both air deflection and air volume regulation can be achieved via the flap arrangement. The flaps are swiveled together to regulate the air volume.

The air deflection device therefore requires fewer components than known designs in order to perform the same functions. In particular, it is therefore possible to dispense with a second lamella arrangement, the lamellae of which in the prior art are pivotably mounted essentially orthogonally to the first lamellae.

The control element can be pivoted parallel to the second pivot axis. In addition, the control element can be connected to the first section of the control flap via a coupling rod. The coupling rod is used to pivot the two flap wings independently of one another. For this purpose, the control element can be pivoted about the second pivot axis and transmits the movement to the first section of the control flap via the coupling rod. The first section is then pivoted about the second pivot axis, the second section being pivoted accordingly. If, for example, the first section is pivoted downwards or laterally, the second section is displaced upwards or laterally. This results in a pivoting of a first flap wing, which is pressed upwards or to the side via the second section, depending on the orientation of the housing. Incoming air is then directed downwards or to the side via this flap and flows against a lower or side wall of the housing. The housing can have a taper in the area of an air outlet opening, so that the air flows along the housing wall following the taper and is deflected, for example, upwards or laterally. The control element is coupled to the coupling rod for this purpose such that pivoting the control element upwards leads to pivoting the first section downwards and vice versa.

In a further embodiment, the coupling rod can have a first bearing section which has a bearing ball and is pivotably mounted in the region of the second pivot axis with the control flap, and a second and a third bearing section which extend from the first bearing section and in bearing receptacles of the control element and are recorded in the area of the first pivot axis. For this purpose, the coupling rod can have a plurality of bearing balls which are accommodated in corresponding receptacles. The mounting of the coupling rod is simple in this embodiment and reduced to the essential functions. The coupling rod is mounted in the control flap in the region of the second pivot axis via the first bearing section. Apart from this, the coupling rod has an orthogonally extending arm, at the end of which, for example, a bearing ball is received in a corresponding receptacle in the first section of the control flap. Furthermore, the coupling rod has a second bearing section, which lies opposite the first bearing section. The second bearing section can also have a bearing ball, which is received in the region of the first pivot axis in the at least one lamella. A further arm of the coupling rod extends therefrom, which extends orthogonally to the main extension of the coupling rod and has, for example, a bearing ball at its end, which forms the third bearing section. The bearing ball in the third bearing section is received in a corresponding receptacle of the control element.

The slat can be pivoted by moving the control element to the side. A displacement of the control element about an axis running parallel to the second pivot axis causes a displacement of the further arm of the coupling rod, the first arm and the further, second arm of the coupling rod running essentially parallel to one another. The coupling rod is pivotably mounted in the corresponding receptacles via the first bearing section and the second bearing section and thus allows a parallel displacement of the first arm, which thus pivots the first section of the control flap and causes the corresponding flap wing to pivot. In addition, the coupling rod can be supported via the bearing balls in the first bearing section and in the second bearing section Swiveling the at least one slat without the control flap being blocked and / or being given away unintentionally.

In an alternative embodiment, the coupling rod can have a first bearing section which is pivotably mounted about a bearing axis extending between the operating element and the flap arrangement, and a second and a third bearing section which extend from the first bearing section and in bearing receptacles of the operating element and the first section are included. The second and the third bearing section are located away from the bearing axis, so that a displacement of the control element can automatically cause the coupling rod to rotate about the bearing axis and thus also to pivot the third bearing section. E.g. pivoting the control element about an axis running parallel to the second pivot axis leads to a deflection of the second bearing section. For this purpose, the second bearing section is accommodated in a bearing holder of the control element. The third bearing section is received in a bearing receptacle of the first section of the control flap. This enables the control flap to be pivoted by appropriately pivoting the control element without the at least one slat pivoting.

The first bearing section can have a bearing ball, via which the coupling rod is mounted at a first bearing point, and have a bearing journal, via which the coupling rod is supported at a second bearing point. The bearing axis extends through the bearing points. At least one of the bearing points only allows rotation about the bearing axis, so that the function of the coupling rod is ensured with a simple and essentially play-free bearing.

The second bearing section and the third bearing section can have a bearing ball. The bearing balls enable the bearing to be stored in the bearing, without jamming and thus blocking.

The control element can be displaced parallel to the second pivot axis and can be coupled to the at least one lamella via a linkage. The linkage can have a lever, which is non-rotatably coupled to an axis of rotation, pivot pin or rod, which are part of the operating element. The control element can be displaced in such a way that a front part can be displaced laterally, and at the same time it can be displaced about a pivot axis that is orthogonal to it. For example, the control element can have two pivot pins which are pivotally mounted in the housing. The rotary pins are connected to the front part of the control element via connecting elements (e.g. second slats). If the control element is moved to the side, the pivot pins are automatically pivoted about third pivot axes. A transfer to the linkage then takes place, a first lever, which is connected to a rotary pin, and a second lever coupled to the first lever being displaced. The second lever can, for example, engage in a receptacle which is arranged apart from the pivot axis of the at least one lamella, or a lamella coupled to the at least one lamella via a driver, or which is provided in a driver. A shift of the control element thus causes the at least one slat to pivot.

The at least one lamella or a lamella coupled to the at least one lamella via a driver can be connected to a turntable which is coupled to a mechanism for jointly pivoting the two flap wings. As a result, the flaps of the flaps can be pivoted together and air can be throttled. The flaps of the flaps are only pivoted together when the at least one slat has been pivoted, for example by a maximum pivoting path for this. The turntable is arranged in the region of the pivot axis of the at least one lamella. The turntable can, in particular, be arranged in the region of a bearing journal and can be integrally formed or fastened thereon and have a gearwheel section via which the movement is transmitted.

The mechanism can have a control plate with a guide link, in which a lever arrangement is guided, which is coupled to the two flap wings. The flap wings can each have a lever, which are coupled together. For this purpose, a pin can protrude laterally from the lever arrangement and is received in the link guide. In a neutral position of the flap wing, the pin is in a central position of the guide link. In a pivoted state of a flap wing, the pin is in a position different from the neutral position in the guide link. For this purpose, the link guide can have an arcuate guide link. If the control plate is moved, the pin that rests against a wall of the guide link is pulled along. As a result, the joint displacement of both flap wings is achieved. The curved shape of the guide link ensures that after opening the air duct of the housing, the original position of a flap wing is restored or that the corresponding flap wing remains in its position.

The control plate may have a rack section that has a gear arrangement is coupled to the turntable. For this purpose, the turntable can have a gearwheel section which engages with the gearwheel arrangement, the control plate likewise engaging with another gearwheel of the gearwheel arrangement via its rack section. The gearwheel arrangement can, for example, have a shaft on which at least two gearwheels are arranged, which are in engagement with the gearwheel section or the rack section or can be brought into engagement. E.g. can be brought into engagement only after a certain pivoting of the at least one slat and thus a definable displacement of the turntable.

For this purpose, the turntable can have a gearwheel section which is not in engagement with the gearwheel arrangement in a neutral position of the control element and can be brought into engagement with the gearwheel arrangement by displacement of the control element along a direction running parallel to the second pivot axis.

The control element can be pivotally connected to two second slats, which are pivotably mounted about a third pivot axis running parallel to the first pivot axis and are coupled to the at least one blade via the linkage. The second lamellae (connecting elements) are pivotably mounted in the housing via rotary pins, as already mentioned above.

The air deflection device can furthermore have two air guiding elements which extend transversely over an air outlet opening of the housing and between which the operating element is mounted. The air guiding elements can have a curvature directed towards one another. This further supports and improves air deflection. The opposite air guiding elements each have a curvature that essentially corresponds to the adjacent housing section. The air guiding elements can also follow the shape of the housing.

The above-mentioned object is also achieved by an air vent which has an air deflecting device which is designed in accordance with the above statements.

An advantage of the air deflection device described here, in addition to the small number of components and the combination of functions (air deflection and air throttling) in the flap arrangement, is to be seen in maintaining a position of the flap wings in the event of air deflection. An air deflection can thus be set, for example one flap wing being deflected or pivoted, while the other flap wing is in its neutral position and is oriented essentially parallel to opposite side walls of the housing. If a joint swiveling of the flap wing is initiated by a lateral displacement of the control element, the air volume being throttled, the undeflected flap wing is swiveled and - depending on the swivel position of the already swiveled flap wing - a further swiveling of the swiveled flap wing. As a result, the amount of air can be regulated by both flap vanes until the air duct of the housing is completely blocked. If the air duct is now released again by moving the operating element back into the starting position, the flap wing which has already been pivoted is only pivoted back as far as was previously the case. This is achieved on the one hand by the fact that the pivoting position of the operating element is not changed during the lateral displacement and thereby the alignment of the second section of the control plate is maintained, and also by the arcuate guide link of the link guide because the deflected state is maintained without this Affects the relocation of the control plate.

The flap wings are pivoted together when the control plate is displaced orthogonally to the first pivot axis. If a flap wing has already been swiveled, the pin is located within the guide link at a point deflected towards the neutral position. If the control plate is then shifted, the pin is shifted to the position at which it is currently located, as a result of which the shifting of the pin and thus the pivoting of the other flap wing are not hindered or restricted.

Further advantages, features and design options result from the following description of the figures of exemplary embodiments that are not to be understood as restrictive.

Detailed description of exemplary embodiments

The 1 to 12th show different views of an air vent and the components thereof. In particular, the air deflecting device is shown in different views, components being partially hidden.

First embodiment

The 1 to 11 show different views of an air vent 200 with an air deflector 10th as well as components thereof. The air vent 200 the first embodiment is described below with reference to FIG 1 to 11 described.

The air vent 200 has a housing 20 with one connection 26 on. About the connection 26 is the air vent 200 connected to an air duct, which in turn is connected to a ventilation device, such as a vehicle air conditioning system. The in the area of the connection 26 Air flowing into the housing through an air inlet opening 20 and flows through this. The housing shows on the front 20 as well as the air vent 200 an air outlet 28 on which the air is discharged. The air vent 200 can, as in 1 shown, horizontally or vertically, i.e. rotated by 90 degrees, can be arranged in a vehicle. For example, the air vent 200 be arranged as a side vent on the edge of a dashboard next to a side door. The air vent 200 is in the embodiment shown as an air vent 200 trained for motor vehicles. In further embodiments, not shown, the air vent can 200 can also be used for aircraft, ships, rail vehicles and / or commercial vehicles. This may require modification to the air vent 200 to adapt to the relevant circumstances. In addition, the air vent 200 have a different appearance.

In the embodiment shown, the air vent has 200 in the area of the air outlet opening 28 two fixed air guiding elements 22 on. Between the air control elements 22 is a control element 40 arranged. A housing wall extends on the underside 24th essentially parallel to the air guiding elements 22 and is like the air control elements 22 executed slightly curved to effect an air deflection of the outflowing air. The housing has at the opposite upper section 20 no housing section designed in this way with a housing wall 24th on. The upper housing section is formed by a vehicle door (not shown in FIG.), Which has a corresponding section. When the vehicle door is closed, this creates an air vent 200 provided, the two air guide elements in the middle section 22 and two housing walls on the outside 24th having.

The air control elements 22 can have a light-guiding element in other embodiments in the region of the front edge or can be designed to be illuminated in some other way. Likewise, the housing walls 24th be illuminated at the front edge. The lighting can be achieved by means of inserted light guides or by means of translucent plastics. For example, the air guiding elements 22 consist entirely of a translucent plastic, the air guide 22 are coated so that light can only escape through exposed or exposed areas. The light can be coupled in via laterally arranged lamps, such as light-emitting diodes. The light can also be introduced by means of light guides which are flexible. The components of the air vent 200 are made of plastic and can be manufactured in an injection molding process. In the exemplary embodiments shown, there is only one spring 58 (please refer 2nd ) from a metal. The remaining components are plastic parts.

The air vent 200 points in the housing 20 Openings in which bearing journal 32 of slats 30th are arranged. The slats 30th are about first swivel axes S ₁ pivoted in the housing (see 5 ). The slats 30th have coupling pins away from the pivot axis, which in openings of a driver 38 are included. About the driver 38 are the slats 30th coupled together so that the pivoting of a slat 30th automatic synchronous swiveling of the other slats 30th causes.

The control element 40 is between the air control elements 22 laterally displaceable and thereby causes the slats to pivot 30th . Tilting of the control element 40 about a parallel to a second pivot axis S ₂ running axis causes flap wings to pivot 88 a flap arrangement 80 , both for air deflection by an orthogonal to air deflection over the fins 30th extending axis as well as throttling the air flow.

2nd shows a view of components of the air vent 200 from 1 from above. The upper air guide 22 as well as the housing 30th are not shown in the illustration. The control element 40 is about coupling pieces 46 (please refer 5 ) with second slats 50 coupled. The second slats 50 have bearing shafts 54 with trunnion on which the second slats 50 pivotable between the air guiding elements 22 are stored as in 5 shown further. The second slats 50 are about the bearing shafts 54 about third swivel axes S ₃ (please refer 9 ) pivoted. The coupling pieces 46 enable a lateral shift of the control element 40 between the air guiding elements 22 without causing the control element to pivot 40 around a parallel to the swivel axis S ₃ running axis through the control element 40 is coming. The control element 40 has a rearward projecting section with a bearing holder 42 in which a bearing ball 71 a coupling rod 70 is recorded. The coupling rod 70 extends substantially in the longitudinal direction of the air flow path through the housing 20 and has an arm 72 and an arm 74 on, with the arm 72 essentially orthogonal to the main direction of the coupling rod 70 and the arm 74 inclined to the main extension of the coupling rod 70 extend. At the ends of the arms 72 and 74 are the bearing ball 71 and a bearing ball 75 (please refer 9 ) arranged. About a bearing ball 73 is the coupling rod 70 between a bearing shaft 54 a second slat 50 rotatably mounted. The bearing ball 73 allows pivoting of the coupling rod 70 around a in the longitudinal direction of the coupling rod 70 extending axis, whereby there is also a pivoting of the bearing balls 71 and 75 around the main extension of the coupling rod 70 is coming. For swiveling the coupling rod 70 becomes the control element 40 around a parallel to the swivel axis S ₂ extending axis swiveled up or down. Via the coupling rod 70 the movement is on the valve assembly 80 transferred so that there is a corresponding pivoting of an upper flap wing 88 or a lower flap wing 88 is coming. For this is the bearing ball 75 in a warehouse 86 of a first section 82 a control flap 81 added. The control flap 81 points to the first section 82 and a second section 84 on, which is about the pivot axis S ₂ opposite. The second section 84 is between the flap wings 88 recorded so that a pivoting of the first section 82 downward to pivot the second section 84 upwards and thus swiveling the upper flap wing 88 leads (see 9 ). The front section is pivoted accordingly 82 upward to a corresponding pivoting of the second section 84 about the pivot axis S ₂ down so the lower wing 88 is pivoted downwards.

The coupling rod 70 can be rotated about the longitudinal axis. There is an additional bearing shaft for this 76 provided their stock 78 in corresponding housings in the housing 20 are included. The bearing shaft 76 has a central circular opening in which a corresponding circular portion of the coupling rod 70 is recorded. Twisting the coupling rod 70 can therefore only take place around its length.

2nd also shows that on the bearing shaft 54 the second slat 50 on the right side a damping disc 56 is arranged in sections in a groove of the lower air guide 22 is recorded. The tongue is also located in this groove 58 that against the circumference of the damping disc 56 presses so that damping is provided. The damping enables a required minimum torque to be set when the air guiding element is displaced 40 to the left or right and ensures that the selected swivel positions can be maintained. The groove in the lower air guide 22 can also determine the extent to which the second slats pivot 50 can take place because then the damping element 56 abuts on wall sections of the groove (see also 11 ).

3rd shows a bottom view of components of the air deflector 10th of the air vent 200 . One of the bearing shafts 54 assigns one Bearing journal 51 on in a corresponding opening in the air guide 22 is recorded. The other bearing shaft 54 has a bearing journal 52 with a rectangular cross-section on, in a corresponding receptacle of a lever arm 62 is recorded. The lever arm 62 has a tick 64 on that in an opening of a lever 60 is recorded. The lever 60 again has a tick 61 on. The hook 61 is in an opening of a lever arm 34 added to the side of a slat 30th extends (see 2nd ). A rotation of the second lamella 50 about the pivot axis S ₃ causes the bearing journal to rotate 52 with the rectangular profile so that the lever arm 62 is pivoted accordingly. Over the lever 60 the movement is on the lever arm 34 transmitted, which then pivots the associated slat 30th causes. About the driver 38 all slats are pivoted 30th in sync with each other.

A slat mounted on the side 30th points instead of a journal 52 a bearing plate on a wall of the housing surrounding an opening 30th lies on. A connecting pin of the slat protrudes through the opening 30th with a rectangular profile. This connecting pin is in a corresponding opening 92 a turntable 90 added (see 10th ). The rotation of the slat 30th therefore also causes a rotation of the turntable 90 around the first pivot axis S ₁ . The hub 90 is designed as a circular segment element and has a gear section 94 on. In a neutral position of the slats 30th is the gear section 94 the turntable 90 spaced from a first gear 114 a gear arrangement 110 . The gear arrangement 110 (see for example 10th ) has a wave 112 on, at the ends of a first gear 114 and a second gear 116 are arranged. The gears 114 and 116 each have a gear section that does not extend around the entire circumference. The wave 112 is so in the air vent 200 stored that this in a neutral position of the slats 30th not engaged with the gear section 94 the turntable 90 stands. If the slats 30th by moving the control element 40 over the linkage, consisting of lever arm 62 and lever 60 , are pivoted, the turntable is also rotated 90 . To a certain extent the slats pivot 30th or a shift of the control element 40 this has no effect on the gear arrangement 110 . Only after passing a maximum position, the slats 30th are pivoted by a definable amount, the gear section 94 the turntable 90 in engagement with the first gear 114 . If the turntable is moved again 90 therefore becomes the first gear 114 around the wave 112 twisted. This leads accordingly to a displacement of the second gear 116 that with a rack section 104 is engaged directly with a control plate 100 is coupled. A rotation of the gear assembly 110 around the wave 112 therefore leads to a shift of the rack section 104 and thus the control plate 100 . The control plate 100 has a leadership backdrop 102 on, in which a hook 124 a lever arrangement 120 is recorded.

The formation of the lever arrangement 120 is for example in the 6 , 8th , 9 shown schematically. The lever arrangement 120 includes two levers 122 , which are coupled to one another via a shaft, the shaft at the front end of the hook 124 has that from the management backdrop 102 protrudes. The wave is within the leadership backdrop 102 stored. The levers 122 have hooks at the other end sections, which in corresponding openings of arms 89 are included. The poor 89 are on the flap wings 88 arranged. Will the control plate 100 shifted, the shaft mounted therein is also shifted, which leads to a fanning out of the two flap wings 88 by pivoting leads. The flap wings 88 are about the second pivot axis S ₂ pivotable in the housing 20 stored, shifting the shaft with the levers 122 automatically swiveling the flap wings 88 causes. The shape of the leadership backdrop 102 enables the flaps to pivot together 88 regardless of the swivel position of the individual flap wings 88 . The formation of the management backdrop 102 allows that with an already pivoted flap wing 88 also a relocation of the control plate 100 is possible, with both flap wings 88 then be fanned out, for example to restrict or prevent the air flow. The wave in the leadership backdrop 102 can either be in an upper or in a lower section of the guide link 102 are located.

How the air vent works 200 is such that, for example, by pivoting the control element 40 around a parallel to the swivel axis S ₂ extending axis a pivoting of one of the two flap wings 88 occurs. Then the control element 40 be shifted laterally, pivoting the slats 30th takes place and a further shift of the control element 40 a rotation of the turntable 90 about a first pivot axis S ₁ evokes. This leads to a shift of the control disc 100 being the shaft, which is in the lead frame 102 is recorded, forward towards the air outlet opening 28 is shifted. This also causes a fanning out or pivoting of the other flap wing 88 , so that the air flow is throttled even when the flap is already swiveled 88 can be done. Then you can the maximum air flow can be released again, using the control element 40 is shifted in the opposite direction. This rotates the gear arrangement 110 around the wave 112 so that the control plate 100 in the opposite direction, from the air outlet 28 away, is shifted, which also involves shifting the shaft in the guide link 102 he follows. The previously not swung flap wing 88 then returns to its original position (such as in 8th shown) and the other flap wing 88 maintains its pivoted position as long as the control element 40 accordingly around a parallel to the second pivot axis S ₂ extending axis remains pivoted.

The 11 and 4th to 7 show further views of the air deflector 10th and components of the air vent 100 .

The advantage of the air vent 200 is that on the one hand about the flap arrangement 80 Both air deflection and air throttling can be achieved. An additional assembly, for example additional lamellae or a separate throttle valve, can therefore be dispensed with. The air vent also enables 200 maintaining air deflection during and after throttling an air flow. Engaging the gear section 94 the turntable 90 takes place after swiveling the slats 30th so that the air can be deflected without having to restrict the air flow.

Second embodiment

12th shows a perspective view of components of an air deflection device 10th an air vent 200 a further embodiment.

The second embodiment of the air deflector 10th differs from the first embodiment essentially in that no bearing shaft 76 is required. In this embodiment, the coupling rod has 70 two arms that are substantially orthogonal to the main direction of the coupling rod 70 extend and run parallel to each other. At the ends of the arms 176 are bearing balls 170 arranged. The coupling rod 70 also has a bearing ball at its end portions 172 and a bearing ball 174 on, which is advantageous in the area of the swivel axes S ₁ and S ₂ run.

In the in 12th The second embodiment shown has the control element 40 an arm 114 on which is a seat for the bearing ball 170 includes. The control flap 81 has a bearing axis, which is a receptacle for the bearing ball 174 includes. The arm 176 projecting bearing ball is also in a corresponding receptacle in the first section 82 added. Will the control 40 around a parallel to the swivel axis S ₂ extending axis (in 12th shown schematically) pivoted, this leads to a deflection of the arm 140 and thus twisting the coupling rod 70 around a in the longitudinal direction of the coupling rod 70 extending axis. Similarly, the arm is pivoted 176 and thus a relocation of the first section 82 , so that analogous to the first embodiment, by pivoting the first section 82 a pivoting of the opposite section 84 and thus one of the two flap wings 88 can be achieved.

The storage of the coupling rod 70 over the bearing ball 172 in the slat 30th allows swiveling the flap wings 88 in all positions of the slat 30th .

The second embodiment also differs from the first embodiment in that no second slats 50 are provided. In this embodiment, the two slats shown 30th a protruding approach to that with coupling pieces 46 with the control element 40 connected is. On a linkage with a lever 60 and a lever arm 62 can be omitted further in this embodiment. The two slats 30th can via a driver, not shown, with additional slats 30th be coupled.

The second embodiment additionally offers the advantage of reduced components and a simplification of the air vent 200 . Furthermore, fewer components are provided which protrude into the air duct and would thus cause an additional swirling of the air flowing through.
