Description

Device for operating a screen arrangement for a vehicle roof and vehicle roof for a motor vehicle

The invention relates to a device for operating a screen arrangement for a vehicle roof. The invention further relates to a vehicle roof for a motor vehicle with such a device.

Some motor vehicles have a screen arrangement that can provide an entertainment program if desired and contributes to increased comfort in the motor vehicle. If necessary, such a screen arrangement is provided with a kinematics concept that allows the screen arrangement to be folded in and out as required. It is a challenge to enable such entertainment electronics to be arranged in a space-saving and cost-effective manner and to contribute to the comfort of the motor vehicle.

It is an object on which the invention is based to create a device for operating a screen arrangement for a vehicle roof, which can be implemented in a space-saving manner and can contribute to the comfort of the motor vehicle.

The object is solved by the features of the independent patent claim. Advantageous developments are specified in the dependent patent claims.

A device according to the invention for operating a screen arrangement for a vehicle roof comprises a cross member which is designed to connect to the vehicle roof to be coupled, so that the cross member extends predominantly transverse to a longitudinal axis of the vehicle roof. The device also includes a rollable display that can be wound up and down by means of a display shaft and that is coupled to the cross member. The device also comprises a fixing unit with a fixing bar which is coupled to the display along a lower edge thereof and which is configured to be moved away from the cross member when the display is unwound and towards the cross member when the display is wound up, and in cooperation to clamp the display with the display shaft.

Using the device described, a screen arrangement for a vehicle roof with a rollable display can be implemented, which can be designed to be particularly space-saving and can contribute to increased comfort in the motor vehicle. In comparison to a rigid display, space requirements can be kept low and, in particular when the display is parked, greater headroom for vehicle passengers can be contributed.

Furthermore, the device enables an enlarged view through the vehicle roof, provided that this is designed to be transparent or has a transparent roof element.

The fixation unit enables a reliable fixation of the rollable, flexible display and contributes to a controlled extension and retraction as well as clamping and clamping of the display. The fixing bar is made of aluminum or a glass fiber reinforced plastic, for example, and has sufficient rigidity to enable the display to be reliably attached and stretched. According to a further development of the device, the fixing unit has a carrier layer which is coupled to the display on a front side and which is coupled to the fixing bar in a force-fitting, form-fitting and/or material-fitting manner. In particular, the carrier layer is designed as a plastic element and/or film element, for example as a PET film, and is used for mechanical stability and also implements protection and provides scratch resistance in order to protect the rollable display and to connect it to the fixing bar in a stable and reliable manner can. Furthermore, the carrier layer can contribute to keeping away or absorbing mechanical stress from the display.

The rollable display is implemented in particular as an OLED display and has a predetermined flexible multi-layer structure. Alternatively, the display is embodied as a micro-LED display or an electronic paper display and has a predetermined scrollability. The flexible display can be fully or partially rolled up or bendable and, for example, can be rolled up around a radius of 1 mm to 40 mm in relation to a winding direction, provided the display is set up for this and the functionality of the display is not impaired by correspondingly tight windings.

According to a further development of the device, one of the carrier layer and the fixing bar has one or more fixing openings and the other has one or more fixing elements that are designed to match one another, so that the fixing elements engage in the fixing openings. For example, the Carrier layer several fixation openings each in the form of a slot, while on the fixation bar several fixation elements are each formed in the form of an elongated push button, which form a respective suspension strap. A correspondingly inverse design is also possible. The fixing elements are inserted into the fixing openings provided and form a non-positive and/or positive coupling. Alternatively or additionally, a cohesive coupling can be set up, for example by means of gluing, which reliably connects the carrier layer to the fixing bar.

According to one development, the device has a shielding element that can be wound up and unwound by means of a shielding shaft, the shielding shaft being coupled to the cross member so that the shielding element faces a rear side of the display and defines the rear side when the display is wound up and unwound covered. The shielding element is designed, for example, as a textile roller blind or as a non-transparent layer to conceal the back of the display and existing electronics and/or to form anti-glare protection which prevents or at least reduces unwanted light from entering the back of the display. The shielding element is preferably coupled to the shielding shaft on the one hand and to the fixing bar on the other hand, so that the shielding element can also be unwound when the display is unwound and the fixing bar tensions the shielding element in cooperation with the shielding shaft.

According to a preferred development of the device, one also has a shielding element and a fixing bar or more fixation openings and the other one or more fixation elements, which are designed to match one another, so that the fixation elements engage in the fixation openings. Correspondingly, as described above in connection with the carrier layer, the shielding element can have a plurality of fixing openings which are introduced into it in a predetermined manner and into which the fixing elements of the fixing bar extend. The carrier layer and the

Shielding element each fixing openings, which are predetermined in their position so that based on a coupled state extends a fixing element of the fixing bar through a fixing opening of the carrier layer and through a fixing opening of the shielding element.

According to a further development, the device has a strip-shaped reinforcement element, for example in the form of a metal strip, which is connected to the carrier layer and/or the shielding element in an edge region of the latter. If necessary, both the carrier layer and the shielding element each have such a reinforcing element in an edge region. The respective edge area corresponds to a coupling section in which the carrier layer and/or the shielding element is or is coupled to the fixing bar. As described above in connection with the carrier layer or the shielding element, the reinforcement element can also have one or more fixing openings and can be coupled to the respective component, for example as a perforated or punched metal strip. The reinforcement element can accordingly become particularly stable and secure Contribute support of the respective components to the fixation beam.

According to a further development, the device has display electronics that are coupled mechanically to the fixing bar and to the display in terms of signals and that provide a predetermined electronic functionality. The display electronics are set up in particular to provide a signal and power supply for the display. The display electronics can also have communication capability or a communication connection to an on-board network or an on-board computer of the motor vehicle and be set up for such in order to control an entertainment program through the display in coordination with the on-board computer. The display electronics are preferably arranged on an upper side of the fixing bar and are concealed to the outside by the shielding element and/or lateral screen elements.

In the context of this description, terms such as "top", "bottom", "front", "rear", "top", "bottom" and "horizontal" and "vertical" refer to directions or orientations according to an operational motor vehicle with a Vehicle roof and a device arranged thereon. Accordingly, a bottom edge of the display in an unrolled state is flat

Vehicle interior facing. A common direction of travel is forward, while the rear of the vehicle is located at the rear. The top of the fixation bar is accordingly located between the vehicle roof and the underside of the fixation bar. The display electronics are preferably coupled to the display by means of mechanically flexible circuit electronics, wherein they have a coupling voltage that is set to be smaller than a coupling voltage between the carrier layer and the fixing bar. It can thus be ensured that a mechanical load on the electronic coupling is kept low. Accordingly, the carrier layer is tensioned in a predetermined manner, while the connection of the display electronics to the circuit electronics and to the display is not tensioned or is slightly tensioned.

A vehicle roof according to the invention for a motor vehicle includes a roof element that is designed to be coupled to a roof body of the motor vehicle. The vehicle roof according to the invention also comprises one of the above-described embodiments of the device for operating a screen arrangement, which is coupled to the roof element on a side of the roof element that faces a vehicle interior. The device can be connected directly or indirectly to the roof element by means of the cross member. The cross member can be coupled to the vehicle roof as a stationary cross member or is preferably set up to be movable relative to the vehicle roof. Thus, the cross member and the display attached to it or integrated therein can be moved in a predetermined manner along the longitudinal axis below the vehicle roof and, for example, be moved all the way forward or all the way back.

The roof element is implemented, for example, as a cover system with a glass cover or as a panoramic glass roof. Alternatively, the roof element can also form a non-transparent roof skin of the vehicle roof. The roof element can be set up so that it can be raised or extended and/or it can be stationary be designed with a roof body or movable relative to this.

Due to the fact that the vehicle roof comprises an embodiment of the device, described features and properties of the device are also disclosed for the vehicle roof and vice versa.

The device and the corresponding vehicle roof can contribute to increased comfort in the motor vehicle. The rollable display can be stowed in a particularly space-saving manner and enables an enlarged view through the vehicle roof. In addition, with a movable cross member, a particularly large view through the vehicle roof can be set up and the risk of a head of vehicle passengers colliding is reduced when the display is rolled up and the cross member is moved all the way back to behind the rear vehicle passengers. The fixing bar of the fixing unit can advantageously be used to couple the display and the shielding element and also provide a stable structure for the display electronics or other components. The fixing elements, which are preferably arranged on the fixing bar or formed together with it, can provide a fastening both for the carrier layer and thus the display and for the shielding element. Thus, no separate fixing elements are required for different components.

Exemplary embodiments of the invention are explained in more detail below with reference to the schematic drawings. Show it: FIG. 1 shows a motor vehicle with a vehicle roof in a perspective view,

Elements of the same construction or function are identified with the same reference symbols across the figures. For reasons of clarity, not all of the elements shown are identified with reference symbols in all of the figures.

FIG. 1 schematically shows a perspective view of a vehicle roof 2 of a motor vehicle 1 which comprises a roof element, a cover system or a cover 4 which closes a roof opening in the vehicle roof 2. The cover 4 is, for example, a fixed glass element that cannot move relative to the vehicle roof 2 . Alternatively, the cover 4 can be moved relative to the vehicle roof 2 in order to selectively open and close the roof opening in the vehicle roof 2 . The vehicle roof 2 can also have no cover 4 and can have a recess-free roof skin, for example a foldable or collapsible convertible roof, which can be stowed in a rear area of the motor vehicle 1 . In addition, the vehicle roof 2 can also form a convertible roof with the cover 4, in which the cover 4 is designed in such a way that it can be folded or collapsed. Below the vehicle roof 2, a cross member 13 is arranged, which is designed to be movable relative to a longitudinal axis L. The cross member 13 is a load-bearing beam or a traverse that is directly or indirectly coupled to the vehicle roof 2 and/or the cover 4 .

In connection with this description, terms such as "top", "bottom", "front", "rear", "top side", "bottom side" and "horizontal" and "vertical" also denote directions or orientations according to an operational motor vehicle 1 a vehicle roof 2, as illustrated in FIG. Accordingly, a horizontal plane is spanned by the drawn x-y plane and is oriented perpendicular to the drawn z-direction, which represents a vertical. The longitudinal axis L corresponds to a longitudinal axis of the vehicle and the direction of the arrow drawn represents a normal direction of travel forward. A rear of the vehicle is arranged or formed at the rear. The cross member 13 is thus arranged under the vehicle roof 2 and/or integrated into it and faces a vehicle interior of the motor vehicle 1 .

As will be explained with reference to the following Figures 2 to 68, various devices 10, 20, 30, 40, 50, 60 and 70 allow a comfortable operation, alignment and covering of a screen arrangement that is coupled to the cross member 13, arranged on it and/or is integrated in this. The devices 10 and/or 20 and/or 30 and/or 40 and/or 50 and/or 60 work together in a particularly advantageous manner, but can also be provided individually in order to provide respective functionalities. Devices 10-70 can be used to implement a screen arrangement for vehicle roof 2 with at least one display 11, 12, which can be designed to be particularly space-saving and can contribute to increased comfort in motor vehicle 1.

Figures 2-12 show an embodiment of a device 10 for operating the screen assembly for the vehicle roof 2 in different views. In the figures 13-16 further views and / or components of the device 10 and / or the devices 20, 40 and / or 70 are shown.

According to FIG. 2, the cover 4 is preferably designed as a transparent roof element, which allows a view through the vehicle roof 2. The cover 4 is designed, for example, as a transparent pane and forms a panorama roof that is firmly connected to a roof body 3 of the motor vehicle 1 . In FIG. 2, the device 10 is arranged in a rear area or in a rear area of the vehicle roof 2 or moved to the rear and stowed away.

The device 10 includes a rollable display 11 which can be wound up and unwound by means of a display shaft 14 and which is coupled to the cross member 13 . The display shaft 14 is coupled to the cross member 13 by means of a shaft connection 16 (see FIGS. 10-13). The cross member 13 is coupled to the vehicle roof 2 so that it mainly extends transversely to the longitudinal axis L. A main extension direction or longitudinal extension direction of the cross member 13 thus essentially leads from one side of the vehicle roof 2 to the opposite side of the vehicle roof 2. The scrollable display 11 is implemented in particular as an OLED display and is also referred to as the first display 11 in the following description. The rollable display 11 can be designed as a flexible screen that can be rolled up or bent in whole or in part.

In addition to the first display 11, the device 10 has a further display 12, which is coupled to the cross member 13 at a distance from the first display 11 in relation to the longitudinal extension direction of the cross member 13.

The further display 12 is designed as a rigid display and is also referred to as the second display 12 in the following description.

In this context, it is pointed out that, according to a preferred embodiment, the device 10 comprises two rollable displays instead of one rollable and one rigid display 11, 12, which are coupled next to one another with the crossbeam 13 or are integrated into it. For reasons of describability, however, advantages of the configuration of the rollable, first display 11 in connection with the rigid, second display 12 are described or illustrated.

FIG. 3 shows the vehicle roof 2 without a transparent cover 4, in which the cross member 13 has been moved all the way to the rear and the first and the second display 11, 12 have been retracted or adjusted. Because the first display 11 is a scrollable display, the illustrated rest or parked position corresponds to a rolled-up condition in which it is at least mostly disposed about the display shaft 14 . The wound up state can also be referred to as the idle state of the first display 11 . In addition the coiled state can also be referred to as a state in which the first display 11 is set, retracted, clamped, rolled up, or stowed.

Since the second display 12 is a rigid display, the rest position or parking position illustrated corresponds to a folded-in state in which it is folded up and extends essentially along the vehicle roof 2 or the cover 4 . The collapsed state can also be referred to as the idle state of the second display 12 . In addition, the folded state can also be referred to as a state in which the second display 12 is adjusted, retracted, flipped up or retracted.

A central position is illustrated in FIG. 4, which was set up by moving the cross member 13 forward until a desired position below the vehicle roof 2 or the cover 4 is reached. In addition, the two displays 11 and 12 are shown in their respective displayed state, in which they are ready to output an entertainment program.

The issued state of the first display 11 can also be referred to as the operating state. In addition, the issued state can also be referred to as a state in which the first display 11 is extended, stretched, unrolled or unwound. The issued state of the second display 12 can also be referred to as the operating state. Furthermore, the issued state can also be referred to as a state in which the pivotable, second display 12 is folded out, folded down or extended. The displays 11 and 12 are oriented in such a way that, based on an operationally extended state, their respective light-emitting front side is aligned backwards in the direction of the rear of the vehicle. In relation to the longitudinal axis L that is drawn in, the device 10 has the rollable display 11 on the left side of the crossbeam 13 and the fixed display 12 on the right side. An alternative arrangement is possible.

FIG. 5 shows a further perspective view of the device 10, in which the cross member 13 is moved all the way forward in relation to the longitudinal axis L and the indicated direction of travel. The two displays 11 and 12 are still ready to output in their respective operating states. Such a foremost position of the cross member 13 is useful, for example, when the motor vehicle 1 is designed as an autonomous vehicle and enables automated driving. In addition, such an entertainment position of the displays 11, 12 can also be specified when the motor vehicle 1 is parked, for example, to take a break from driving.

The movability of the cross member 13 is set up by means of a guide system 60 and in this regard reference is made in particular to the following description with regard to FIGS. 64-68.

FIG. 6 shows the extended displays 11 and 12 on the movable crossbeam 13 in an oblique view from behind. FIG. 7 shows a corresponding view of the extended displays 11 and 12 in a view from above, in which the cross member 13 provides a view of the displays 11,

12 covered.

In FIG. 8, the retracted displays 11 and 12 on the movable crossbeam 13 are shown in an oblique view from behind. FIG. 9 shows a corresponding view of the retracted displays 11 and 12 in a view from above. An advantage of the rollable display 11 is immediately apparent from FIG. A particularly large gain in transparency can thus be set up through the cover 4, which corresponds, for example, to half the length or height of the rigid display 12. The scrollable display 11 thus contributes to a screen arrangement which, in comparison with a fold-out, rigid display, enables an enlarged view and offers an advantage in terms of installation space.

FIGS. 10 and 11 show an exemplary embodiment of the display shaft 14 onto which the rollable display 11 is wound up or from which the rollable display 11 is unwound. The display shaft 14 is designed in a cylindrical and rotationally symmetrical manner. The display shaft 14 is designed as a hollow shaft and surrounds a shaft axis 15. The shaft connections 16 are arranged on opposite sides of the display shaft 14 and are coupled to the shaft axis 15.

A plurality of clamping elements in the form of drive springs 17 are arranged between the display shaft 14 and the shaft axis 15 . Based on a longitudinal direction of the Display shaft 14 are three mainsprings 17 arranged at opposite free ends. The drive springs 17 are each coupled to the display shaft 14 on the one hand and to the shaft axis 15 on the other hand and are set up to tension the display 11 in a predetermined manner when it is unwound from the display shaft 14 and wound onto the display shaft 14 . The drive springs 17 form a preferred variant of internal spring elements, which contribute to the fact that the rollable display 11 can be operated and stowed away in a small space and that a useful force build-up for tensioning the rollable display 11 is provided.

The rollable display 11 and the display shaft 14 are designed in such a way that they are matched to one another in such a way that they together have a diameter in the range of 40-100 mm in relation to a wound-up state and a radial direction transverse to the longitudinal direction of the display shaft 14 .

FIG. 12 shows the device 10 with the crossbeam 13 and the display shaft 14 in a partially sectioned side view. The cross member 13 has a housing 131 in which the display shaft 14 is arranged. Accordingly, the rollable display 11 can be arranged in a hidden state in the housing 131 when it is wound up on the display shaft 14 . FIG. 12 shows the scrollable display 11 in an extended state. A retracted state of the scrollable display 11 is shown in FIG.

In the figures 12-16 further kinematic components are illustrated, for example, an extension movement of the scrollable displays 11 control. The device 20 capable of doing this is also referred to as a guide mechanism 20 and is described below in connection with FIGS. 17-27. In addition, the device 40 and elements thereof are also illustrated in FIGS. 12-16. The device 40 is also referred to as a fixing unit 40 and in this regard reference is made in particular to FIGS. 43-45 and the associated description. Furthermore, components of the device 70 are shown, which is also referred to as a cover unit 70 and provides a cover for the display 11 that can be folded in and out. The veneering unit 70 is described below in particular in connection with FIGS. 69-75.

The device 10 further includes a shielding element 19 , for example in the form of a roller blind, which can be wound up and down by means of a shielding shaft 18 . The shield shaft 18 is coupled to the cross member 13 and disposed in the case 131 like the display shaft 14 . The shielding element 19 is assigned to a rear side 112 of the rollable display 11 so that it covers the rear side 112 in a predetermined manner when the first display 11 is rolled up and down.

The shield member 19 is coupled to the shield shaft 18 at an upper end on the one hand and to the fixing unit 40 at a lower end on the other hand. The same applies to the rollable display 11, which is coupled to the display shaft 14 on the one hand at an upper end and to the fixing unit 40 on the other hand at a lower end (see FIG. 16). When the shielding element 19 and the rollable display 11 are unwound, the fixing unit 40 is moved by means of the guide mechanism 20 of FIG moved away from the crossbeam 13 and upon winding up the shielding member 19 and the display 11 to the crossbeam

13 moved. The shield shaft 18 and the display shaft

14 are designed to be coordinated with one another, so that the shielding element 19 and the display 11 can be wound up and unwound synchronously.

Analogously to FIGS. 12 and 13, FIGS. 14 and 15 show an extended and a retracted state of the first, scrollable display 11 with a view of

Kinematic components of the guide mechanism 20 without showing the first display 11 and the shielding element 19. The guide mechanism 20 enables reliable unwinding and stable clamping as well as winding and clamping of the rollable display 11 and the shielding element 19. For this purpose, the guide mechanism 20 has a plurality of guide levers 21, 22, 23, which can be moved electrically by means of a drive unit 24. The drive unit 24 is designed in particular as a central drive with an electric motor.

According to FIG. 12, some guide levers 22, 23 are also designed as lateral cover elements 72, 73 or are coupled with such in order to form an attractive lateral closure or visual protection for the unrolled display 11. In particular, the illustrated form of such screen elements can contribute to comfortable visual protection and reliable operation of the guide mechanism 20 . The shielding element 19 forms a screen that can be rolled up and conceals cabling and/or electronic control components of the display 11 that can be rolled up in the extended state. The guide levers 22 and 23 form a corresponding panel as a laterally folding lateral privacy screen on opposite sides of the rollable display 11. A tensioned state of the unwound display 11, as illustrated in FIG. Correspondingly, a tensioned state of the unwound shielding element 19, as illustrated in FIG.

Figures 17-27 show various views of the vehicle roof 2 with the device 10 and exemplary embodiments of the guide mechanism 20 for the controlled setting and adjusting of the scrollable display 11. Figures 17-21 show different positions and states of the device 10 and in perspective views the guide mechanism 20 for operating the screen assembly.

Figures 22-27 show exemplary embodiments of the guide mechanism 20 in more detail.

For reasons of clarity, only the scrollable display 11 is illustrated in FIGS. 17-27, if visible. The guide mechanism 20 is therefore described in connection with the scrollable display 11 . However, the further, second display 12 is to be arranged on the cross member 13 next to the first display 11 that can be rolled, preferably as a further rollable display.

FIG. 17 shows the device 10 in the parking position, in which it is stowed at the rear in the area of the rear of the vehicle and the display 11 is retracted. FIG. 18 shows the device 10 in a first intermediate position, with the display 11 still being retracted or rolled up.

FIG. 19 shows the device 10 in the first intermediate position according to FIG. 18, with the display 11 being extended or unclamped.

FIG. 20 shows the device 10 in a further position, in which the cross member 13 is moved all the way forward and the display 11 is retracted or rolled up.

FIG. 21 shows the device 10 in the foremost position according to FIG. 20, with the display 11 being extended or unclamped.

Extending or rolling out and retracting or clamping in again takes place by means of the guide mechanism 20, which can be designed according to FIGS. 22-27. Figures 22 and 23 deal with the guide mechanism 20, which includes a turnstile 25. An alternative embodiment of the guide mechanism 20 is shown in FIGS. 24-27, according to which the guide mechanism 20 has a lever mechanism 26 .

The guide mechanism 20 is coupled to the cross member 13 and includes a plurality of guide levers 21,

22, 23, which are coupled to the rollable display 11 and set up to stretch the display 11 when it is unwound from the display shaft 14 and to clamp it when it is wound onto the display shaft 14. With respect to a right and a left side of the display 11, a first guide lever 21, a second guide lever 22 and a third guide lever 23 arranged. In the following, one side of the guide mechanism 20 is therefore mainly described, with the properties being transferrable to the other side accordingly. If necessary, differences are pointed out with reference to the right and left side of the guide mechanism 20 or the scrollable display 11 .

The first guide lever 21 is pivotably coupled to the turnstile 25 or the lever mechanism 26 on the one hand and pivotably coupled to the second guide lever 22 on the other hand, which can also be designed as a screen element (see FIG. 12). On the right-hand side, the coupling position of the first guide lever 21 with the turnstile 25 or the lever mechanism 26 forms a first pivot axis S1. On the left-hand side, the coupling position of the first guide lever 21 with the turnstile 25 or the lever mechanism 26 forms a second pivot axis S2.

The second guide lever 22 is on the one hand pivotable relative to the crossbeam 13 and on the other hand pivotally coupled to the third guide lever 23 . The coupling of the second guide lever 22 to the cross member 13 can be set up directly or indirectly. The third guide lever 23 is pivotably coupled to the second guide lever 22 on the one hand and pivotably coupled to the fixing unit 40 on the other hand.

The guide mechanism 20 and the guide levers 21, 22, 23 can each be controlled by means of the drive unit 24 and can be folded out and in electrically. The electric drive unit 24 is arranged on the cross member 13 and for example integrated in the housing 131 and coupled to the turnstile 25 or the lever mechanism 26 . By means of the drive unit 24, a rotation of the turnstile 25 or the lever mechanism 26 and thereby a pivoting of the guide levers 21, 22, 23 and a winding or unwinding of the rollable display 11 can be initiated.

The first and second guide levers 21 and 22 are designed as elongated articulated links in terms of their shape, while the third guide lever 23 is designed in a straight line. Such a preferred configuration can contribute to a particularly space-saving folding in of the guide mechanism 20 and stowage of the scrollable display 11 . The guide levers 21, 22, 23 can in particular be designed as stable and narrow metal components in order to enable reliable unwinding and opening of the display 11 and also to be able to be folded up and stowed away to save space. Alternatively, one or more of the guide levers 21, 22, 23 can be designed as plastic components.

The guide mechanism 20 forms a scissor mechanism in each case, by means of which the pivot axes S1 and S2 and the guide levers 21, 22, 23 are guided in a controlled manner. By means of the scissor mechanism with the turnstile 25, according to FIGS. 22 and 23, the pivot axes S1 and S2 can be guided one above the other. FIG. 22 shows a retracted or folded-in state of the scissor mechanism, in which the display 11 is rolled up and the guide levers 21, 22, 23 are stowed away in a bent position. In this state, the second pivot axis S2 is arranged above the first pivot axis S1 in relation to a vertical line. Between the two pivot axes S1 and S2 is a rotation axis R3 of the Turnstile 25 formed or arranged. FIG. 23 shows an extended or unfolded state of the guide mechanism 20 in the form of a scissor mechanism according to FIG. Thus, in the retracted and in the extended state, one of the pivot axes S1, S2 is arranged above the other and above the axis of rotation R3 of the turnstile 25.

The guide mechanism 20 in the form of a scissor mechanism with the lever mechanism 26 according to Figures 24-27 enables an even more space-saving arrangement of the display 11 in or on the cross member 13 compared to the embodiment with the turnstile 25. The lever mechanism 26 comprises two gear elements 27, 28 , which are coupled to the drive unit 24 on the one hand and to the first guide lever 21 on the other hand. The first gear member 27 is rotatable about a first axis of rotation RI and the second gear member 28 is rotatable about a second axis of rotation R2. The gear elements 27 and 28 mesh with one another with their tooth structures, so that only one gear element can be driven by the drive unit 24 in order to also move the corresponding other side of the guide levers 21, 22, 23. Alternatively, both gear elements 27, 28 can also be driven by the drive unit 24, and an embodiment is also possible in which the gear elements 27, 28 are not in contact with one another. By means of the drive unit 24, a rotation of the gear elements 27, 28 of the lever mechanism 26 and thereby a pivoting of the guide levers 21, 22, 23 and a winding or unwinding of the rollable display 11 can be initiated. FIG. 24 shows a retracted or folded-in state of the scissor mechanism with lever mechanism 26, in which the display 11 is rolled up. In this state, both pivot axes S1 and S2 are arranged approximately at the same height relative to a vertical and above the axes of rotation RI and R2 of the gearwheel elements 27 and 28 . Thus, the fixing unit 40, which is coupled to a lower edge 111 of the scrollable display 11 with this, can be moved closer to an underside of the drive unit 24 than is the case in the embodiment with the turnstile 25. The fixing unit 40 can be coupled to the rollable display 11 in sections or completely along the lower edge 111 . Thus, the guide mechanism 20 and the rollable display 11 can be stowed particularly flat on an underside of the vehicle roof 2 and a contribution can be made to greater headroom for vehicle passengers.

FIG. 25 shows an extended or unfolded state of the guide mechanism 20 in the form of a scissor mechanism according to FIG.

The guide levers 21, 22, 23 are coupled to the drive unit 24 on the one hand and to the fixing unit 40 on the other hand, which is coupled to the display 11 that can be rolled along the lower edge 111 of the latter. The fixing unit 40 is thus moved towards the cross member 13 by means of the guide levers 21, 22, 23 when the display 11 is wound up. As described above with reference to Figures 12-16, the shielding element 19 by means of Guide mechanism 20 are unwound from its shielding shaft 18 and wound onto it.

Figures 26 and 27 show the guide mechanism 20 with the lever mechanism 26 in a perspective view in a retracted state according to Figure 24 and in an extended state according to Figure 25. In addition, components of the guide system 60 are illustrated, which enable the mobility of the cross member 13. In this regard, reference is made to the following description with regard to FIGS. 64-68.

The guide mechanism 20 implements a space-saving and reliable guide linkage for the scrollable display 11. The guide mechanism 20 is designed in particular in such a way that the scrollable display 11 can be continuously extended and retracted, so that desired intermediate positions can also be set up, in which the scrollable display 11 is not fully retracted or extended. Thus, for example, the lower edge 111 of the scrollable display 11 can be adjusted to a desired height in the vehicle interior. Alternatively, the guide mechanism 20 can also provide several predefined intermediate positions, so that the display 11 can be extended and retracted step by step. Alternatively, the guide mechanism 20 can also be designed in such a way that the display 11 can only be fully retracted or extended.

FIGS. 28-42 show various views of the device 30, which is also referred to as the tilting mechanism 30 below. The tilting mechanism 30 enables a double tilting of the first, scrollable display 11 and the second, rigid displays 12. The displays 11 and 12 can accordingly be tilted or tilted in relation to a horizontal, first plane EA1 and in relation to a vertical, second plane EA2 (see FIGS. 33 and 35).

FIG. 28 shows the vehicle roof 2 in a plan view, with the two displays 11 and 12 being retracted into the parking position.

FIG. 29 shows an intermediate position of the crossbeam 13 with retracted displays 11 and 12 in a perspective view. FIG. 30 shows the vehicle roof 2 according to FIG. 29 in a plan view.

FIG. 31 shows the intermediate position of the cross member 13 with the displays 11 and 12 extended in a perspective view. FIG. 32 shows the vehicle roof 2 according to FIG. 31 in a plan view.

FIG. 33 shows the foremost position or a front position of the cross member 13 with the displays 11 and 12 extended in a plan view. FIG. 34 shows the vehicle roof 2 according to FIG. 33 in a plan view with retracted displays 11 and 12.

FIG. 35 shows the retracted displays 11 and 12 in a sectional view along the second plane EA2 looking backwards. FIG. 36 shows the vehicle roof 2 according to FIG. 35 in a perspective view. FIGS. 37 and 38 show the vehicle roof 2 according to FIGS. 35 and 36 with extended displays 11 and 12 looking backwards.

FIGS. 38A and 38B schematically show kinematic components for folding the second, rigid display 12 in and out and for tilting it in an unfolded and a folded-in position.

Figures 39 and 40 show the kinematic components for folding out and folding in and tilting the second, rigid display 12 in lateral sectional views perpendicular to the longitudinal axis L. In Figure 39, the second display 12 is folded up or in and in Figure 40 is the second display 12 partially or fully folded down or exposed. A desired inclination of the second display 12 relative to the vertical can be set by means of a lever mechanism 37 .

Figures 41 and 42 show kinematic components for folding and unfolding and for tilting the first, flexible display 11 in sectional views along the longitudinal axis L. In Figure 41, the first display 12 is retracted or wrapped and in Figure 42 the second display 12 is fully extended and stretched.

The tilting mechanism 30 comprises a plurality of guide elements 31-36 which couple the respective display 11 or 12 to the cross member 13. The guide elements 31-33 are assigned to the second display 12 and can also be referred to as first, second and third cross member coupling 31-33. The guide elements 34-36 are the first display 11 assigned, which include a link guide element 34, a link track 35 and a guide pin 36.

The guide elements 31-36 are set up to align the respective display 11, 12 with respect to an associated lower edge 111, 121 in a deployed state along a first axis A1, A2 and in a set state along a second axis A3, A4. The first axis A1, A2 is oriented within the first plane EA1, which is spanned by the longitudinal axis L and the direction of longitudinal extension of the cross member 13. The first level EA1 corresponds to a horizontal level. The first axis A1 of the first display 11 and the first axis A2 of the second display 12 can be adjusted in such a way that they each enclose an angle of less than 90° with the longitudinal axis L in an extended state (see FIGS. 32 and 33). The smaller angle between the axis A1 or A2 and the longitudinal axis L is to be referred to as the included angle. According to FIG. 32, in relation to the illustrated point of intersection of the axis A1 with the longitudinal axis L, the angle at the top right (to the rear of the vehicle) or at the bottom left (to the front of the vehicle) is to be referred to as the included angle. With regard to axis A2, the angle at the top left (to the front of the vehicle) or at the bottom right (to the rear of the vehicle) is to be designated as the included angle.

The second axis A3, A4 of the displays 11, 12 is oriented within the second plane EA2, which is perpendicular to the first plane EA1 and represents a perpendicular plane perpendicular to the longitudinal axis L. The second axis A3 of the first display 11 and the second axis A4 of the second display 12 can each be set in such a way that, in a set state, they form an angle greater than 0° with the first plane EA1 (see Figures 29, 35 and 36). Here, too, the smaller angle between the axes A3 or A4 and the horizontal plane EA1 is to be regarded as the included angle. According to Figure 35 is thus related to an intersection of the axis A3 with the (because of the

For clarity (not shown) horizontal plane EA1, the angle at the bottom right (towards the outside of the vehicle) or at the top left (towards the center of the vehicle) is to be designated as the included angle. With regard to axis A4, the angle at the bottom left (to the outside of the vehicle) or at the top right (to the center of the vehicle) is to be designated as the included angle.

Thus, the displays 11 and 12 can each be set in an exposed state with a predetermined inclination along their first axes A1, A2 and in a set state with a predetermined inclination along their second axes A3, A4.

The first axes A1 and A2 take into account a viewing direction or a line of sight of a vehicle passenger who is generally not seated in the center in front of the respective display 11, 12 in the motor vehicle 1, but is placed slightly offset from the center of the display. The displays 11 and 12 can therefore be tilted outwards in a predetermined manner with respect to their light-emitting front sides towards the respective outside of the vehicle, so that a line of sight essentially corresponds to a normal direction of the front side of the associated displays 11, 12 (see FIG. 32).

By means of the possibility of adjustment along the second axes A3 and A4, the displays 11 and 12 can be stowed higher in the center of the vehicle than in the area of the outer sides. The screens 11 and 12 can thus be stowed in a parking position by means of the tilting mechanism 30 in such a way that they extend predominantly along the vehicle roof 2 or the cover 4. The vehicle roof 2 and the cover 4 are usually not flat within a horizontal plane, but are rather curved in a predetermined manner and are oriented higher in their center than at their lateral edge when mounted on the motor vehicle 1 . Using the described

Inclination mechanism 30, the curvature of vehicle roof 2 and cover 4 can be taken into account and contribute to increased headroom for vehicle passengers (see FIGS. 35 and 36).

The tilting mechanism 30 of the first display 11 and the tilting mechanism 30 of the second display 12 are each set up in such a way that the respective second axis A3, A4 coordinates with the vehicle roof 2 and/or the cover 4 and a position of the display 11, 12 the underside of the vehicle roof 2 is specified such that the associated display 11, 12 in the set state follows a shape of the vehicle roof 2 and/or the cover 4 along the longitudinal direction of the cross member 13 and essentially parallel to the vehicle roof 2 and/or the Lid 4 is set.

The tilting mechanism 30 of the first display 11 includes the link guide element 34, which is coupled to the cross member 13 and has a link track 35, in which the guide pin 36 engages and within which the guide pin 36 can be guided in a predetermined manner. The guide pin 36 is formed on the second guide lever 22 of the guide mechanism 20 or with the second guide lever 22 coupled and thus specifies, together with the first guide lever 21, a guided movement of the second guide lever 22 when adjusting and adjusting the scrollable display 11 (see FIGS. 41 and 42).

The tilting mechanism 30 of the second display 12 comprises a lever mechanism 37 which is coupled to the cross member 13 and by means of which the second display 12 can be folded out and in. The lever mechanism 37 includes the three cross member couplings 31, 32, 33, which are designed to be of different sizes and pivotable, so that the second display 12 changes from a set state in which the lower edge 121 of the second display 12 is aligned along an initial axis A0 (see Figure 34). The output axis A0 is oriented perpendicular to the longitudinal axis L within the first plane EA1. In this way, the second display 12 is not aligned obliquely within the horizontal plane in the set parking position below the vehicle roof 2 . Edges of the second display 12 are thus essentially parallel or perpendicular to the longitudinal axis L in the folded state. The second display 12 is inclined along the second axis A4 with respect to the horizontal first plane EA1 (see FIGS. 35-36).

The first cross member coupling 31 pivotally couples the second display 12 to the cross member 13 and has a pivot axis S6. The pivot axis S6 also corresponds to the pivot axis of the third crossbeam coupling 33. Referring to the illustration illustrated in FIG. The second cross member coupling 32 is accordingly arranged centrally and has three pivot axes S7, S8 and S9 up. The second cross member coupling 32 comprises a link lever 321 and a further lever 322. The link lever 321 is pivotably coupled to the cross member 13 on the one hand and pivotably coupled to the lever 322 on the other hand. Lever 322 is also pivotally coupled to display 12 (see Figure 40). The link lever 321 comprises a link in which a guide pin, for example of the drive unit 24, engages, which, when driven, causes the link lever 321 to pivot and the display 12 to fold in or out.

The above-described inclined positions of the second display 12 can be set up reliably and stably by means of the described cross-beam couplings 31, 32, 33 and the pivot axes S6-S9 assigned to them. In relation to a horizontal axis, the pivot axes S6-S9 run at a predetermined angle in order to form the described inclined positions of the second display 12.

The slanting mechanism 30 or 37 enables the second display 12 to be brought into an open state, in which the second display 12 is aligned with a predetermined slanting position along the first axis A2 (see FIGS. 35-40). Furthermore, the first and second displays 11 and 12 can be raised by means of their tilting mechanisms 30 in such a way that their lower edges 111, 121 are aligned essentially horizontally (see FIGS. 37-38).

FIGS. 43-45 show a side sectional view of the device 40, which is also referred to as the fixation unit 40. FIG. The fixing unit 40 is coupled to the lower edge 111 of the first, scrollable display 11 and includes a fixing bar 42 that extends along the lower edge 111 of the Displays 11 extends and is set up to be moved away from the cross member 13 by means of the guide mechanism 20 when the display 11 is unwound and to be moved toward the cross member 13 when the display 11 is wound up. The fixing unit 40 tensions the rollable display 11 in cooperation with the display shaft 14 and preferably also the shielding element 19 in cooperation with the shielding shaft 18.

The fixing unit 40 has a carrier layer 41 which is coupled to the rollable display 11 on a front side 113 thereof. The carrier layer 41 is designed in particular as a film element, for example as a PET film, and serves, among other things, to protect the display 11 and to provide a stable and reliable connection to the fixing bar 42. It also contributes to mechanical stability and provides scratch resistance, to protect the rollable display 11 from surface damage. The carrier layer 41 is coupled to the fixing bar 42 on an underside 421 in a force-fitting, form-fitting and/or cohesive manner.

The fixation bar 42 has in each

Deflection areas, in which the shielding element 19 and the carrier layer 41 are deflected, have a rounded contour in order to enable reliable and gentle tensioning of the respective elements. The fixing bar 42 is made, for example, from aluminum or a glass fiber reinforced plastic and has sufficient rigidity to enable the display 11 to be reliably attached and clamped. Like the shielding element 19 , the carrier layer 41 has a plurality of fixing openings 48 into or through which a plurality of fixing elements 43 formed or arranged on the underside 421 of the fixing bar 42 extend.

The fixing elements 43 and the fixing openings 48 are preferably designed to match one another in terms of their shape and number. For example, the fixing bar 42 is designed as a plastic molded part in one piece with the fixing elements 43, each in the form of an elongated push button, which form a respective hanging tab and are set up equidistantly on the underside 421 (see FIG. 44). FIG. 44 shows a schematic view of the fixing bar 42 from below. The fixing openings 48 are designed in the form of a slot into which the fixing elements 43 are inserted.

Both the shielding element 19 and the carrier layer 21 each have fixing openings 48, the position of which is designed in such a predetermined manner that a respective fixing element 43 of the fixing bar 42 extends through an associated fixing opening 48 of the shielding element 19 and an associated fixing opening 48 of the carrier layer 21 . Thus, a non-positive and/or positive connection of the shielding element 19 and the carrier layer 41 with the fixing bar 42 can be set up. Alternatively or additionally, the shielding element 19 and/or the carrier layer 41 can be glued to the fixing bar 42 . According to FIG. 45, the carrier layer 41 and/or the shielding element 19 has a strip-shaped reinforcing element 49, for example in the form of a perforated metal strip, in a respective edge region in which it is coupled to the fixing beam 42. The respective edge region can thus be reinforced in order to set up a particularly reliable and stable coupling of the carrier layer 41 and/or the shielding element 19 to the fixing bar 42 .

The fixing unit 40 also includes display electronics 44 which are mechanically coupled to the fixing bar 42 on a top side 422 . The display electronics 44 are also coupled in terms of signals to the scrollable display 11 by means of a coupling interface 46 and a flexible circuit unit 47 and provide a predetermined electronic functionality for the display 11, for example in coordination with an on-board computer of the motor vehicle 1. A coupling voltage between the circuit unit 47 and the display electronics 44 is preferably set to be smaller than a coupling voltage between the carrier layer 41 and the fixing bar 42. The circuit unit 47 is designed, for example, as flexible printed circuit electronics.

The shielding element 19 is designed, for example, as a textile element in the form of a blind or as a non-transparent layer in order to shield the electronic and/or mechanical components on the rear side 112 of the rollable display 11 . Furthermore, the fixing unit 40 has a facing 45 which is connected to the fixing bar 42 or the shielding element 19 and the underside 421 Backing layer 41 is coupled to aesthetically pleasingly conceal the coupling positions of these elements. In addition, the cover 45 has contours that are rounded outwards or in the direction of the vehicle interior in order to contribute to safe headroom for vehicle passengers.

FIGS. 46-63 show different views of the device 50, which is also referred to as cable storage unit 50 below. The cable storage unit 50 enables a reliable data and power supply of the first, rollable display 11 and the second, rigid display 12.

Figures 46 and 47 each show a perspective view of the arrangement of

Cable storage unit 50 in the rear area of the vehicle roof 2. Alternatively, the cable storage unit 50 can be integrated in a front area of the vehicle roof 2.

Figures 48-60 show the cable storage unit 50 in different views.

Figures 61-63 illustrate schematically

Exemplary embodiments of possible tension concepts in order to keep the supply cables 51, 52 of the cable storage unit 50 taut.

The cable storage unit 50 has a first supply cable 51 and a second supply cable 52 which provide a respective data and/or power supply for the displays 11 and 12 . Accordingly, the first supply cable 51 can be connected to the first display 11 and the second supply cable 52 to the second display 12 be assigned in terms of supply. This can include a data supply and/or a power supply. Alternatively and preferably, the data supply and the power supply are located separately from one another, so that, for example, the first supply cable 51 provides a respective power supply for the two displays 11 and 12 and the second supply cable 52 provides a respective data supply for the two displays 11 and 12. A separate supply is particularly important for voltage reasons and with regard to electromagnetic compatibility and/or

beneficial from a safety perspective. The supply cables 51 and 52 each form sheathed energy chains which have coupling structures 58 which, in cooperation with cable guides 57, enable the supply cables 51, 52 to be routed in a stable, reliable and low-noise manner. If no such energy chain covering is useful, uncovered sections 56 and 59 of the umbilical cables 51, 52 are also provided.

The cable guides 57 are arranged on opposite sides of the vehicle roof 2 and enable the supply cables 51, 52 to be routed in a controlled manner from the very rear to the very front in the vehicle roof 2. In order that such a relatively large mobility of the cross member 13 can be set up, the supply cables 51, 52 arranged one above the other in a housing 54 (s. Figures 50-53). The housing 54 is set up to store and release the supply cables 51, 52 and is integrated in a rear transverse beam of the vehicle roof 2. Alternatively, it can be integrated into a front cross member or cowl of the vehicle roof 2 . So that the supply cables 51, 52 can be reliably guided over one another, there is, for example, between the supply cables 51, 52 a partition wall is provided in the housing 54, which forms a floor for the upper umbilical cable 52. A floor for the lower supply cable 51 is realized through the housing floor.

The supply cables 51, 52 are fixed in place at one end, which faces away from the respective display 11, 12, for example by means of a fixing hook (not shown). Starting from the fixed end, the supply cables 51, 52 run through the housing 54 and emerge from the housing 54 through a respective deflection 55 on the side associated with them. The deflection 55 is formed with the housing 54 or is coupled to it and is set up to deflect the supply cables 51 , 52 and to align them along the longitudinal axis L and to introduce them into the cable guides 57 . The deflections 55 can in particular be formed in one piece by means of injection molding together with the housing 54 and any partitions and covers. The supply cables 51, 52 pass through the cable guides 57 to the associated display 11,

12. Furthermore, an uncovered section 56 of the supply cables 51, 52 is illustrated (see FIG. 53).

The supply cables 51, 52 thus run in sections along the longitudinal axis L on a respective side of the vehicle roof 2 within the cable guide 57 and in sections in the housing 54, with the supply cables 51, 52 running in opposite directions in inclined planes E1 and E2 above one another and in each case have a U-shaped change of direction in order to be able to provide a sufficiently long supply line. The figure 52 illustrates the possible movements of the U-shaped change of direction of the two supply cables 51, 52 when the Cross member 13 is moved closer to the cable storage unit 50 or moved further away from it.

FIG. 56 illustrates the housing 54, which comprises the obliquely oriented first plane E1 and the obliquely oriented second plane E2. The horizontal plane EA1 is also drawn in to illustrate the deliberately predetermined inclination. The first level El is arranged below the second level E2 relative to a vertical, the first supply cable 51 being assigned to the first level El and the second supply cable 52 to the second level E2 of the housing 54 .

The oblique storage of the supply cables 51, 52 within the housing 54 enables useful accommodation and also a transfer of the respective supply cables 51, 52 to the common plane EA1 outside of the housing 54, so that the supply cables 51, 52 are guided at the same height in the cable guides 57 can become. Torsion or tension when transferring the supply cables 51, 52 from their respective planes E1, E2 to the horizontal plane EA1 by means of the deflections 55 is tolerable.

The supply cables 51, 52 each have sliding carriages with sliders 53, which enable low-resistance guidance of the supply cables 51, 52 within a guide channel of the associated cable guide 57 (see FIGS. 58-60). From the cable guides 57, the supply cables 51, 52 for the flow and data supply enter the cross member 13 and pass through it to the respective display 11, 12 (see FIG. 54). Such a connection is in the figure

54 illustrated in which the umbilical cords 51, 52 each have an uncovered portion 59 which leads to the respective displays 11, 12 and can be installed in the cross member 13 or its housing 131 to save space. The cross member 13 and the displays 11, 12 attached to it are not shown in FIG. 54 for reasons of clarity.

The cable storage unit 50 also preferably includes a tensioning mechanism 591,592,593, as shown in Figures 60-63, which is coupled to the respective umbilical cord 51,52 and exerts a predetermined tensioning force on the umbilical cord 51,52.

For example, such a tensioning mechanism is implemented in the form of a tensioning linkage coupled to the opposing sliding carriage. Alternatively or additionally, as shown in Figure 61, a tensioning element 591, 592 is provided in the area of the respective U-shaped change in direction of the supply cables 51, 52 in the housing 54, which is designed to be displaceable or stretchable and exerts a tensioning force on the respective supply cable 51, 52. Such a tension element 591, 592 can be realized, for example, as a tension spring or cable connection.

Alternatively or additionally, a tensioning coupling can be set up between the two supply cables 51, 52, as is shown schematically in FIGS. The two tensioning elements 591 and 592 are coupled to the associated supply cables 51, 52 and a further tensioning element 593, which exerts a force so that the supply cables 51, 52 remain tensioned in a predetermined manner. The further tension element 593 can be a Provide torque or a tensile force acting on the two tension elements 591, 592.

The tension concepts described can help to keep noise levels low when the supply cables 51, 52 are being moved and also allow the supply cables 51, 52 to exit and enter the housing 54 in a controlled and guided manner. Furthermore, a flexible cover of the housing 54 can be designed to match the geometry of the supply cable(s) 51, 52 and contact or overlap the upper supply cable 52 in a predetermined manner in order to prevent or counteract rattling of the supply cables 51, 52 in the housing 54 .

By means of the cable storage unit 50, a reliable and secure data and power supply for the two displays 11, 12 can be implemented, which is also provided when the

Cross member 13 can be moved along the longitudinal axis L over the entire or the greatest possible length below the vehicle roof 2 . The supply cables 51, 52 are provided with a corresponding length, so that they have a length of more than 140 cm, for example. Such a length of the supply cables 51, 52 relates to a corresponding movability of the cross member 13, from which point it is advantageous to arrange the supply cables 51, 52 one above the other in the housing 54 in the cross member at the front or rear of the vehicle roof 2. If less movability is provided, so that the supply cables 51, 52 should only provide a movable length of 50 cm-100 cm, for example, storage in the housing 54 can be provided within a common, in particular horizontal, plane. For example, the umbilical cords 51, 52 a movable length of 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 110 cm, 120 cm, 130 cm, 140 cm, 150 cm, 160 cm, 170 cm, 180 cm, 190 cm or 200 be designed in a coordinated manner.

FIGS. 64-68 show the device 60, which is also referred to as the guidance system 60, in different views. The guidance system 60 enables reliable and safe guidance of the cross member 13 and the displays 11, 12 arranged thereon along the longitudinal axis L.

FIGS. 64-66 show perspective views of the vehicle roof 2 and the cross member 13 coupled thereto in various travel positions. FIG. 64 illustrates the cross member 13 in a parking position, in which it is stowed, for example, at the very back in the area of the rear of the vehicle below the vehicle roof 2. Figure 65 shows the crossbar 13 in an intermediate position with the displays 11, 12 folded up or retracted. Figure 66 shows the crossbar 13 in a forward position with the displays 11, 12 folded up or retracted. The crossbar 13 can be moved continuously by means of the guide system 60 , so that any number of intermediate positions between the foremost and the rearmost position can be set as required.

FIGS. 67 and 68 show components of the guide system 60 in a respective perspective view. The guide system 60 has cross member guide elements in the form of two guide rails 61 which are coupled or can be coupled to the vehicle roof 2 on opposite sides in relation to the longitudinal axis L. The cross member 13 is coupled on opposite sides with a guide carriage 64 in a respective Guide channel of the associated guide rail 61 are arranged.

The guidance system 60 further comprises an electric drive unit 63, in particular in the form of an electric motor, which is coupled to an associated guide slider 64 by means of a respective drive cable 62, so that the guide sliders 64 can be controlled by means of the drive unit 63 and the cross member 13 can be moved electrically along the longitudinal axis L is. Alternatively or additionally, manual displacement of the cross member 13 can also be set up. As indicated in FIG. 67, the drive unit 63 can be arranged in a rear area of the vehicle roof 2 or alternatively in a front area of the vehicle roof 2. In particular, the cable storage unit 50 and the guide system 60 are arranged in the vehicle roof 2 in a coordinated manner.

A secure and controlled guidance of the crossbeam 13 can be formed by means of the guidance system 60 . The displays 11 and 12 are arranged on the crossbeam 13 and can be moved with it, and a comfortable position of the displays 11 and 12 for outputting an entertainment program can be set. In addition, the generous movability of the cross member 13 enables the view through the cover 4 to be released without being restricted upwards in the center of the vehicle by the cross member, guide rails or other view-obstructing components.

The greatest possible view through the vehicle roof 2 can thus be achieved, which is felt to be particularly comfortable in particular in connection with a transparent panorama roof as the roof element. FIGS. 69-75 show the device or the veneering unit 70 or components thereof in different views. The covering unit 70 enables a visually appealing cladding of the first, rollable display 11 and covers specified sections in order in particular to conceal mechanical and/or electrical connections and also to avoid unwanted light irradiation on the rear side 112 of the display 11 .

The veneer unit 70 has a first

Veneering element 71, two second facing elements 72, two third facing elements 73 and a fourth facing element 74 (s. Figures 71-75). The first facing element 71 is arranged on or in the cross member 13 and is coupled to it and implements an upper connection component for the further facing elements 72-74. The fourth facing element 74 is coupled to the lower edge 111 of the display 11 and forms a lower terminating component. The second and third facing elements 72, 73 are arranged on opposite sides from the first to the fourth facing element 71, 74 relative to a vertical central axis M of the facing unit 70 and are connected to the first and the fourth facing element 71, 74, so that the second and third facing elements 72, 73 couple the first facing element 71 to the fourth facing element 74.

The fourth facing element 74 can implement the facing 45 according to FIGS. 13-16 and 43 or, alternatively, be designed in addition to it. Accordingly, the fourth facing element 74 can be coupled to the fixing bar 42, for example screwed, clipped on and/or glued (see Figure 69-72). The cover unit 70 and in particular the fourth cover element 74 are preferably designed to be matched to a geometry and an appearance of the housing 131 of the cross member 13 . For example, the housing 131 and the fourth facing element 74 have the same material, the same surface structure, coordinated edge profiles and/or the same curvature, so that a contribution can be made to a uniform and particularly attractive appearance.

In the retracted state of the rollable display 11, which is associated with a set state of the foldable cover unit 70, the fourth cover element 74 closes the housing 131 of the cross member 13 on an underside, so that all other components of the cover unit 70 are hidden in the housing 131 of the cross member 13 are stowed. Therefore, the fourth facing element 74 that closes at the bottom is preferably adapted to the housing 131 of the cross member 13 in a predetermined manner and can be designed uniformly with it or intentionally set up a contrast to it.

The cover unit 70 is coupled to the cross member 13 and set up to be folded in when the display 11 is rolled up and to be folded out when the display 11 is unrolled and, in relation to a lateral edge of the display 11, has a cover frame along the lateral edge of the display 11 to train (see Figures 73-75).

The mutually associated second and third facing elements 72, 73 are each coupled pivotably to one another by means of a hinge element 75. Correspondingly, a pivot axis S4 is set up at the coupling position between the second and third facing elements 72, 73. Furthermore, the second facing elements 72 are, on the other hand, pivotably coupled to the first facing element 71 . Accordingly, at the coupling position between the second

Veneering elements 72 and the first veneering element 71 set up a pivot axis S3. Furthermore, the third facing elements 73 are, on the other hand, pivotably coupled to the fourth facing element 74 . Accordingly, at the coupling position between the third

Veneering elements 73 and the fourth facing element 74 set up a pivot axis S5.

In this way, the cover unit 70 can be designed in the form of a cover frame that can be folded in and out, which provides an aesthetic covering around the display 11 and can also be folded in to save space and stowed in the housing 131 of the cross member 13 . When folding in, the two second and third facing elements 72, 73 are moved toward one another at the coupling position of the pivot axis S4 (see FIGS. 71 and 72). The pivot axis S4 follows a horizontal and vertical course of movement. The pivot axis S5 essentially follows a vertical course of movement. The pivot axis S3 remains essentially fixed in position. If necessary, a certain movement of the pivot axes S3 and/or S5 in the vertical and/or horizontal direction is also designed in a predetermined manner in order, for example, to stow away the cover unit 70 with a predetermined inclined position, as is the case in connection with the inclined position mechanism 30 according to Figures 28 -42 is described. The covering unit 70 can also include a fifth covering element in the form of a shading element, which forms a shield for covering the rear side 112 of the display 11 . The fifth facing element is implemented in particular as the previously described shielding element 19, which can be wound up and down by means of the shielding shaft 18 (see FIGS. 60-70 and 73-74). Alternatively, the fifth facing element can form an additional element which faces the rear side 112 of the display 11 and covers the rear side 112 in a predetermined manner when the display 11 is wound up and down.

The facing elements 71-74 are designed in the form of plates and, with respect to a lateral extension, are shaped transversely to a respective thickness in accordance with a respectively available installation space. In particular, the second and third facing elements 72, 73 are designed in a predetermined manner with respect to their lateral extent in coordination with an intermediate space between the developed display 11 and the fifth facing element or the shielding element 19 (see FIG. 12). The

Veneering elements 71-74 and/or the housing 131 can be made of aluminum or plastic or have a mix of materials. Furthermore, for example, the facing elements 72-74 can be implemented as fabric-covered components in order to set up a desired look.

The veneering unit 70 is preferably designed to be coordinated with the devices 10-60 described above. In particular, the second and third facing elements 72 and 73 can cover the guide levers 22 and 23 of the guide mechanism 20 (see FIGS. 14 and 22-25). Alternatively, the second and third facing elements 72, 73 and the guide levers 22, 23 can form separate elements, so that the second and third facing elements 72, 73 conceal the guide levers 22, 23 in a predetermined manner and set up a view of the guide mechanism 20 on the inside. Furthermore, the folding out of the cover unit 70 can be controlled automatically by means of the drive unit 24 of the guide mechanism 20 . Alternatively or additionally, a separate drive unit can be provided for folding the cover unit 70 in and out.

In addition, the veneering unit 70 is preferably, as illustrated in FIG. 75, adapted in its form to one or more functions of the devices 10-60. The first facing element 71 therefore has a first coupling section 76 and an opposite second coupling section 77 to the respective second facing elements 72, which are configured differently. Correspondingly, the second facing elements 72 have different coupling structures to the first facing element 71 . The first facing element 71 also has a projection 78 . The illustrated configurations of the first cover element 71 and the second cover element 72 connected thereto are particularly dependent on reliable folding out and compact folding in of the cover unit 70, opening up and retracting the display 11 by means of the guide mechanism 20 and/or a predetermined tilting of the extended and/or retracted displays 11 adjusted by means of the tilt mechanism 30.
