Description

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

background

Air vents are used to divert air released by an air conditioning system or other ventilation device. Air vents are used in particular in vehicles to bring fresh air, temperature-controlled air and/or air-conditioned air into the passenger compartment of a vehicle. Vehicles can be, for example, motor vehicles such as cars, trucks or buses, trains, airplanes or ships. With the air vent, in addition to controlling the deflection of air emitted, for example from an air conditioning system, the amount of air emitted 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 a control element. To do this, the control element must carry out 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 separate control. Another disadvantage is that the known devices require additional installation space due to the large number of components, which is often only available to a limited extent in vehicles.

Control devices for air vents are also known from the prior art, with slats being able to be pivoted via a control element, for which purpose the control element is displaced in one direction. In addition, a throttle valve that is pivotably mounted parallel to the slats can be pivoted during a further displacement in the same direction.

EP 1 752 324 B1 discloses an air nozzle with slats that can be pivoted via a control wheel, the slats being coupled to one another via a coupling element and the coupling element engaging with the control wheel, so that turning the control wheel causes the slats to pivot. The operating wheel has a peripheral section with a gear-shaped contour, which is operatively connected via further components with gear contours to a flap for controlling the flow cross section within the air nozzle. The control wheel can also be in operative connection with the flap to control 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, with the slats and the closing flap being controlled via a common control element, which only has to be moved in one direction in order to realize both movements. In these devices, the slats coupled to a control element and the closing flap coupled to the control element are arranged so 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 slats pivotably mounted parallel to it have been pivoted.

These operating devices are limited to slats and throttle valves, which are mounted around pivot axes that run parallel to one another.

However, with regard to the operation of variously designed air vents, such restrictions are to be viewed as disadvantageous. In addition, it shows EP 1 752 324 B1 known operating device has the disadvantage that there is a direct coupling between the displacement of the flap and the slats via the operating wheel, so that a displacement of the slats always causes a displacement of the flap.

Conventional operating devices, which only have ordinary arrangements for air deflection and air volume regulation, are out DE 10 2009 020 574 B3 , DE 20 2018 002 957 U1 , DE 10 2016 014 132 A1 , DE 10 2017 118 055 A1 and DE 10 2017 206 464 A1 known.

For example, it reveals DE 10 2009 020 574 B3 an air outlet nozzle, which has a slat arrangement with slats mounted orthogonally pivotable to one another, which can be rotated via an adjustment handle to deflect air, and an additional throttle device, the throttle device being permanently activated synchronously has bare flap parts that are used to control the air volume and can be controlled via a separate link control.

Task

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

Solution

The task is solved by the features of the independent patent claims. Advantageous developments of the invention are characterized in the subclaims.

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

The air deflector therefore requires fewer components than known designs in order to fulfill the same functions. In particular, it is therefore possible to dispense with a second slat arrangement, the slats of which in the prior art are pivotally mounted essentially orthogonally to the first slats.

The operating element can be pivotally mounted 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 each other. 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, with the second section being pivoted accordingly. For example, if the first section is pivoted downwards or laterally, the second section is shifted upwards or laterally. This results in a pivoting of a first flap wing, which is pushed upwards or to the side via the second section - depending on the orientation of the housing. Incoming air is then directed downward or to the side via this flap wing 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 upwards or to the sides, for example. For this purpose, the coupling of the control element to the coupling rod is designed in such a way that pivoting the control element upwards leads to a pivoting of 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 pivotally mounted with the control flap in the area of the second pivot axis, and a second and a third bearing section, which extend from the first bearing section and are in bearing receptacles of the operating element and are recorded in the area of the first pivot axis. For this purpose, the coupling rod can have several bearing balls which are accommodated in corresponding receptacles. The storage of the coupling rod is simple in this version and reduced to the essential functions. The coupling rod is mounted in the control flap in the area of the second pivot axis via the first bearing section. Aside from this, the coupling rod has an orthogonally extending arm, at the end of which, for example, a bearing ball is accommodated in a corresponding receptacle in the first section of the control flap. Furthermore, the coupling rod has a second bearing section which is opposite the first bearing section. The second bearing section can also have a bearing ball which is accommodated in the at least one slat in the area of the first pivot axis. A further arm of the coupling rod extends from this, which runs 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 accommodated 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 operating element about an axis running parallel to the second pivot axis causes a displacement of the further arm of the coupling rod, with the first arm and the further, second arm of the coupling rod running essentially parallel to one another. The coupling rod is over the first bearing section and the second Bearing section pivotably mounted in the corresponding receptacles and thus allows a parallel displacement of the first arm, which thus pivots the first section of the control flap and causes a pivoting of the corresponding flap wing. In addition, the mounting of the coupling rod via the bearing balls in the first bearing section and in the second bearing section enables the at least one slat to be pivoted without the control flap becoming blocked and/or unintentionally lost.

In an alternative embodiment, the coupling rod can have a first bearing section, which is pivotally 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 are mounted in bearing receptacles of the operating element and the first section are included. The second and third bearing sections 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 pivot the third bearing section. For example, pivoting the operating 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 receptacle of the operating element. The third bearing section is accommodated in a bearing receptacle of the first section of the control flap. This enables the control flap to be pivoted by corresponding pivoting of the operating element without the at least one slat being pivoted.

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 pin, via which the coupling rod is mounted at a second bearing point. The bearing axis extends through the bearing points. At least one of the bearing points only allows rotation around the bearing axis, so that the function of the coupling rod is guaranteed with simple and essentially play-free storage.

The second bearing section and the third bearing section can have a bearing ball. The bearing balls enable storage in bearing holders without the risk of tilting and thus a blockage.

The control element can be displaceable parallel to the second pivot axis and coupled to the at least one slat via a linkage. The linkage can have a lever which is coupled in a rotationally fixed manner to a rotation axis, pivot pin or rod, which are part of the control element. The control element can be displaced in such a way that a front part can be displaced laterally, whereby at the same time a displacement can take place about a pivot axis running orthogonally thereto. For example, the control element can have two rotating pins that are pivotably mounted in the housing. The pivot pins are connected to the front part of the control element via connecting elements (e.g. second slats). If the control element is moved laterally, the pivot pins are automatically pivoted around third pivot axes. A transfer then takes place to the linkage, with a first lever, which is connected to a rotating pin, and a second lever coupled to the first lever being displaced. The second lever can, for example, engage in a receptacle that is arranged away from the pivot axis of the at least one slat, or of a slat coupled to the at least one slat via a driver, or which is provided in a driver. A displacement of the control element thus causes the at least one slat to pivot.

The at least one slat or a slat coupled to the at least one slat via a driver can be connected to a turntable, which is coupled to a mechanism for pivoting the two flap wings together. This makes it possible to pivot the flap blades together and thus achieve air throttling. The flap wings are only pivoted together when the at least one slat has been pivoted, for example by a maximum pivoting path. The turntable is arranged in the area of the pivot axis of the at least one slat. The turntable can be arranged in particular in the area of a bearing pin and formed or attached to it and have a gear section through which the movement is transmitted.

The mechanism can have a control plate with a guide slot in which a lever arrangement is guided which is coupled to the two flap wings. The flap wings can each have a lever that is coupled to one another. For this purpose, a pin can protrude laterally from the lever arrangement and is accommodated in the link guide. When the flap wings are in a neutral position, the pin is in a central position of the guide link. When a flap leaf is pivoted, the pin is at a position in the guide link that is different from the neutral position. For this purpose, the link guide can have an arcuate guide link. If the control plate is moved, the pin, which is on a wall of the guide the backdrop is pulled along. This results in the joint displacement of both flap wings. The curved shape of the guide link ensures that after opening the air duct of the housing, the original position of a flap leaf is assumed again or that the corresponding flap leaf maintains its position.

The control plate may include a rack portion coupled to the turntable via a gear arrangement. For this purpose, the turntable can have a gear section which is in engagement with the gear arrangement, with the control plate also being in engagement with another gear of the gear arrangement via its rack section. The gear arrangement can, for example, have a shaft on which at least two gears are arranged, which are in engagement or can be brought into engagement with the gear section or the rack section. For example, engagement can only take place after a certain pivoting of the at least one slat and thus a determinable displacement of the turntable.

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

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

The air deflection device can also have two air guiding elements which extend transversely over an air outlet opening of the housing and between which the control 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 guide elements each have a curvature that essentially corresponds to the adjacent housing section. The air guide elements can also follow the shape of the housing.

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

In addition to the small number of components and the combination of functions (air deflection and air throttling) in the flap arrangement, an advantage of the air deflection device described here is the maintenance of a position of the flap blades during air deflection. An air deflection can be set, for example, one flap wing is deflected or pivoted, while the other flap wing has its neutral position and is aligned essentially parallel to opposite side walls of the housing. If a joint pivoting of the flap wings is initiated by a lateral displacement of the control element, whereby the amount of air is throttled, the non-deflected flap wing is pivoted and - depending on the pivoting position of the already pivoted flap wing - the pivoted flap wing is pivoted further. This allows the amount of air to be regulated until the air duct of the housing is completely blocked by both flap wings. If the air duct is now released again by moving the control element back to the starting position, the previously pivoted flap wing is only pivoted back as far as was the case before. This is achieved on the one hand by the fact that the pivoting position of the control 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 has an impact on the displacement 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 leaf has already been pivoted beforehand, the pin is located within the guide slot at a point deflected to the neutral position. If the control plate is then relocated, the pin is relocated at the point where it is currently located, so that the displacement of the pin and thus the pivoting of the other flap leaf are not hindered or restricted.

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

Detailed description of exemplary embodiments

The 1 until 12 show different views of an air vent and its components. In particular, the air deflection device is shown in different views, with some components being hidden.

First embodiment

The 1 until 11 show various views of an air vent 200 with an air deflection device 10 and components thereof. The air vent 200 of the first embodiment will be described below with reference to 1 until 11 described.

The air vent 200 has a housing 20 with a connection 26. Via the connection 26, the air vent 200 is connected to an air duct, which in turn is connected to a ventilation device, such as a vehicle air conditioning system. The air flowing in in the area of the connection 26 via an air inlet opening enters the housing 20 and flows through it. On the front, the housing 20 and the air vent 200 have an air outlet opening 28 through which the air is emitted. The air vent 200 can, as in 1 shown, can be arranged horizontally or vertically, i.e. rotated by 90 degrees, in a vehicle. For example, the air vent 200 can be arranged as a side vent on the edge of a dashboard next to a side door. In the exemplary embodiment shown, the air vent 200 is designed as an air vent 200 for motor vehicles. In further embodiments not shown, the air vent 200 can also be used for airplanes, ships, rail vehicles and/or commercial vehicles. For this purpose, modifications may be necessary in order to adapt the air vent 200 to the relevant circumstances. In addition, the air vent 200 can have a different appearance.

In the exemplary embodiment shown, the air vent 200 has two fixed air guide elements 22 in the area of the air outlet opening 28. A control element 40 is arranged between the air guide elements 22. On the underside, a housing wall 24 extends essentially parallel to the air guide elements 22 and, like the air guide elements 22, is designed to be slightly curved in order to deflect the outflowing air. At the opposite upper section, the housing 20 does not have a housing section designed in this way with a housing wall 24. The upper housing section is formed by a vehicle door (not shown in figure) which has a corresponding section. When the vehicle door is closed, an air vent 200 is provided, which has two air guide elements 22 in the middle section and two housing walls 24 on the outer sides.

In further embodiments, the air guiding elements 22 can have a light guiding element in the area of the front edge or can be designed to be illuminated in another way. Likewise, the housing walls 24 can be illuminated at the front edge. The lighting can be via inserted light guides or via translucent plastics can be achieved. For example, the air-guiding elements 22 can consist entirely of a transilluminable plastic, with the air-guiding elements 22 being coated so that light can only emerge via exposed or uncovered areas. The light coupling can take place via laterally arranged lamps, such as light-emitting diodes. The light can also be introduced using light guides that are designed to be flexible. The components of the air vent 200 are made of plastic and can be produced in an injection molding process. In the exemplary embodiments shown there is only one spring 58 (see 2 ) made of a metal. The remaining components are plastic parts.

The air vent 200 has openings in the housing 20, in which bearing pins 32 of slats 30 are arranged. The slats 30 are mounted in the housing so that they can pivot about first pivot axes S ₁ (see 5 ). The slats 30 have coupling pins away from the pivot axis, which are accommodated in openings of a driver 38. The slats 30 are coupled to one another via the driver 38, so that pivoting one slat 30 automatically causes the other slats 30 to pivot synchronously.

The control element 40 can be moved laterally between the air guide elements 22 and thereby causes the slats 30 to pivot. Tilting the control element 40 about an axis running parallel to a second pivot axis S ₂ causes the flap wings 88 of a flap arrangement 80 to pivot, which serves both to deflect air an axis running orthogonally to deflect air over the slats 30 and also serves to throttle the air flow.

2 shows a view of components of the air vent 200 from 1 from above. The upper air guide element 22 and the housing 20 are not shown in the illustration. The control element 40 is connected via coupling pieces 46 (see 5 ) coupled to second slats 50. The second slats 50 have bearing shafts 54 with bearing pins, via which the second slats 50 are pivotably mounted between the air guide elements 22, as in 5 shown further. The second slats 50 are connected via the bearing shafts 54 about third pivot axes S ₃ (see 9 ) pivotally mounted. The coupling pieces 46 enable a lateral displacement of the control element 40 between the air guide elements 22 without the control element 40 pivoting about an axis running parallel to the pivot axis S ₃ by the control element 40. The control element 40 has a rearwardly projecting section with a bearing holder 42, in which a bearing ball 71 of a coupling rod 70 is accommodated. 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, the arm 72 extending substantially orthogonally to the main direction of the coupling rod 70 and the arm 74 extending inclined to the main extent of the coupling rod 70 . At the ends of the arms 72 and 74 are the bearing ball 71 and a bearing ball 75 (see 9 ) arranged. The coupling rod 70 is rotatably mounted between a bearing shaft 54 of a second lamella 50 via a bearing ball 73. The bearing ball 73 allows the coupling rod 70 to pivot about an axis running in the longitudinal direction of the coupling rod 70, whereby the bearing balls 71 and 75 also pivot about the main extent of the coupling rod 70. To pivot the coupling rod 70, the control element 40 is pivoted downwards or upwards about an axis running parallel to the pivot axis S ₂ . The movement is transmitted to the flap arrangement 80 via the coupling rod 70, so that a corresponding pivoting of an upper flap wing 88 or a lower flap wing 88 occurs. For this purpose, the bearing ball 75 is accommodated in a bearing receptacle 86 of a first section 82 of a control flap 81. The control flap 81 has the first section 82 and a second section 84, which lie opposite each other about the pivot axis S ₂ . The second section 84 is received between the flap wings 88, so that pivoting the first section 82 downwards leads to a pivoting of the second section 84 upwards and thus to a pivoting of the upper flap wing 88 (see 9 ). Correspondingly, pivoting the front section 82 upwards results in a corresponding pivoting of the second section 84 downwards about the pivot axis S ₂ , so that the lower wing 88 is pivoted downwards.

For this purpose, the coupling rod 70 can be rotated about the longitudinal axis. For this purpose, an additional bearing shaft 76 is provided, the bearings 78 of which are accommodated in corresponding housing receptacles in the housing 20. The bearing shaft 76 has a central circular opening in which a corresponding circular section of the coupling rod 70 is received. The coupling rod 70 can therefore only be rotated along its longitudinal extent.

2 also shows that on the bearing shaft 54 of the second slat 50 on the right side a damping disk 56 is arranged, which is accommodated in sections in a groove of the lower air guide element 22. In this groove there is also the spring 58, which presses against the circumference of the damping disk 56, so that a Damping is provided. The damping makes it possible to set a required minimum torque when moving the air guide element 22 to the left or right and ensures that the selected pivot positions can be maintained. The groove in the lower air guide element 22 can also determine to what extent the second slats 50 can be pivoted, since the damping element 56 then abuts against wall sections of the groove (see also 11 ).

3 shows a view from below of components of the air deflection device 10 of the air vent 200. One of the bearing shafts 54 has a bearing pin 51 which is received in a corresponding opening in the air guide element 22. The other bearing shaft 54 has a bearing pin 52 with a rectangular cross section, which is accommodated in a corresponding receptacle of a lever arm 62. The lever arm 62 has a hook 64 which is received in an opening of a lever 60. The lever 60 in turn has a hook 61. The hook 61 is accommodated in an opening of a lever arm 34, which extends laterally from a slat 30 (see 2 ). A rotation of the second slat 50 about the pivot axis S ₃ causes a rotation of the bearing pin 52 with the rectangular profile, so that the lever arm 62 is pivoted accordingly. The movement is transmitted via the lever 60 to the lever arm 34, which then causes the slat 30 connected to it to pivot. All slats 30 are pivoted synchronously with one another via the driver 38.

A laterally mounted lamella 30 has, instead of a bearing pin 52, a bearing plate which rests on a wall of the housing 20 surrounding an opening. A connecting pin of the slat 30 with a rectangular profile protrudes through the opening. This connecting pin is accommodated in a corresponding opening 92 of a turntable 90 (see 10 ). The rotation of the slat 30 therefore also causes a rotation of the turntable 90 about the first pivot axis S ₁ . The turntable 90 is designed as a circular segment element and has a gear section 94. In a neutral position of the slats 30, the gear section 94 of the turntable 90 is located at a distance from a first gear 114 of a gear arrangement 110. The gear arrangement 110 (see for example 10 ) has a shaft 112, at the ends of which 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 shaft 112 is mounted in the air vent 200 so that it does not engage with the gear section 94 of the turntable 90 when the slats 30 are in a neutral position. If the slats 30 are pivoted by moving the control element 40 via the linkage, consisting of the lever arm 62 and lever 60, the turntable 90 also rotates. Up to a certain degree of pivoting of the slats 30 or a displacement of the control element 40 This has no effect on the gear arrangement 110. Only after passing a maximum position, whereby the slats 30 are pivoted by a definable amount, does the gear section 94 of the turntable 90 come into engagement with the first gear 114. If the turntable 90 is moved further therefore the first gear 114 is rotated around the shaft 112. This accordingly leads to a displacement of the second gear 116, which is in engagement with a rack section 104 which is directly coupled to a control plate 100. A rotation of the gear arrangement 110 around the shaft 112 therefore leads to a displacement of the rack section 104 and thus of the control plate 100. The control plate 100 has a guide link 102 in which a hook 124 of a lever arrangement 120 is received.

The design of the lever arrangement 120 is, for example, in the 6 , 8th , 9 shown schematically. The lever arrangement 120 comprises two levers 122 which are coupled to one another via a shaft, the shaft having the hook 124 at the front end, which protrudes from the guide link 102. The shaft is stored within the guide link 102. The levers 122 have hooks on the other end sections, which are received in corresponding openings of arms 89. The arms 89 are arranged on the flap wings 88. If the control plate 100 is displaced, the shaft mounted therein is also displaced, which leads to the two flap wings 88 fanning out by pivoting. The flap wings 88 are mounted in the housing 20 so that they can pivot about the second pivot axis S ₂ , with a displacement of the shaft with the levers 122 automatically causing the flap wings 88 to pivot. The shape of the guide link 102 enables the flap wings 88 to be pivoted together regardless of the pivoting position of the individual flap wings 88. The design of the guide link 102 makes it possible for the control plate 100 to be moved when the flap wing 88 has already been pivoted, with both flap wings 88 then can be fanned out, for example to throttle or stop the air flow. The shaft in the guide link 102 can be located either in an upper or in a lower section of the guide link 102.

The operation of the air vent 200 is such that, for example, a waste ken of the control element 40 about an axis running parallel to the pivot axis S ₂ , a pivoting of one of the two flap wings 88 occurs. The control element 40 can then be displaced laterally, with the slats 30 pivoting and a further displacement of the control element 40 causing a rotation of the turntable 90 about a first pivot axis S ₁ . This leads to a displacement of the control disk 100, with the shaft, which is accommodated in the guide link 102, being displaced forward in the direction of the air outlet opening 28. This also causes the other flap wing 88 to fan out or pivot, so that the air flow can be throttled even when the flap wing 88 is already pivoted. The air flow can then be maximally released again, with the control element 40 being displaced in the opposite direction. The gear arrangement 110 is rotated around the shaft 112, so that the control plate 100 is displaced in the opposite direction, away from the air outlet opening 28, whereby the shaft is also displaced in the guide link 102. The flap wing 88, which was not previously pivoted, then returns to its starting position (as in, for example). 8th shown) back and the other flap wing 88 maintains its pivoted position as long as the operating element 40 remains pivoted accordingly about an axis running parallel to the second pivot axis S ₂ .

The 11 and 4 until 7 show further views of the air deflection device 10 and components of the air vent 200.

The advantage of the air vent 200 is that, on the one hand, both air deflection and air throttling can be achieved via the flap arrangement 80. Therefore, there is no need for an additional assembly, for example additional slats or a separate throttle valve. In addition, the air vent 200 allows air deflection to be maintained during and after throttling of an air flow. The gear section 94 of the turntable 90 is brought into engagement after the slats 30 have been pivoted, so that the air can be deflected without having to throttle the air flow.

Second embodiment

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

The second embodiment of the air deflector 10 differs from the first embodiment essentially in that no bearing shaft 76 is required. In this embodiment, the coupling rod 70 has two arms which extend essentially orthogonally to the main direction of the coupling rod 70 and run parallel to one another. Bearing balls 170 are arranged at the ends of the arms 176. The coupling rod 70 also has a bearing ball 172 and a bearing ball 174 at its end sections, which advantageously run in the area of the pivot axes S ₁ and S ₂ .

In the in 12 In the second embodiment shown, the operating element 40 has an arm 140, which includes a receptacle for the bearing ball 170. The control flap 81 has a bearing axis which includes a receptacle for the bearing ball 174. The bearing ball protruding from the arm 176 is also accommodated in a corresponding receptacle in the first section 82. If the control element 40 rotates around an _axis (in 12 shown schematically), this leads to a deflection of the arm 140 and thus to a rotation of the coupling rod 70 about an axis running in the longitudinal direction of the coupling rod 70. Analogously, the arm 176 is pivoted and thus the first section 82 is displaced, so that, analogously to the first embodiment, the opposite section 84 and thus one of the two flap wings 88 can be pivoted by pivoting the first section 82.

The mounting of the coupling rod 70 via the bearing ball 172 in the slat 30 allows the flap wings 88 to be pivoted in all positions of the slat 30.

The second embodiment also differs from the first embodiment in that no second slats 50 are provided. In this embodiment, the two slats 30 shown have a forwardly projecting extension which is connected to the operating element 40 with coupling pieces 46. A linkage with a lever 60 and a lever arm 62 can be dispensed with in this embodiment. The two slats 30 can be coupled to further slats 30 via a driver, not shown.

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