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 scrollable display that can be wound up and down by means of a display shaft, the display shaft being coupled to the cross member by means of a shaft connection.

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.

According to a preferred development, the device has at least one tensioning element, which is coupled to the display and is set up to tension the display in a predetermined manner when it is unwound from the display shaft and when it is wound onto the display shaft. The clamping element or elements are intended to provide a useful clamping force for the display that can be rolled up, in order to avoid the formation of creases during opening and hauling, or at least to counteract such.

The display is implemented as an OLED display, for example, which can be rolled up with a given diameter without impairing the electronics and functionality. Alternatively, the display is available as a micro LED display or an electronic paper display designed and set up rollable. The display thus forms an electronically controllable film that can be wound onto the display shaft for storage or unwound from it for operation. In relation to a radial expansion of the usually rotationally symmetrical display shaft, the display shaft, including the rolled-up display, can have a dimension of 40-50 mm or up to 100 mm. The radial expansion is particularly dependent on the size of the display, so that a display with a larger screen diagonal usually has a larger radial expansion than a display with a smaller screen diagonal. According to a further development of the device, the display and the display shaft are designed to be matched to one another, so that when they are wound up and in a direction transverse to a longitudinal extent of the display shaft, they together have a diameter in the range of 40-100 mm.

The display is placed around the display shaft in a coiled state. The wound-up state can also be referred to as the idle state or parked position of the display. In addition, the coiled state can also be referred to as a state in which the display is set, retracted, constrained, rolled up, or stowed.

Accordingly, in a developed state, the display is largely no longer arranged around the display shaft. The display can be fully or partially unwound from the display shaft and output a visual entertainment program. If so, that is Display also set up to emit acoustic signals. For example, the display has built-in speakers and/or has an electronic coupling interface with which a signal-related coupling to an audio system of the motor vehicle can be set up.

A height of the display or a vertical position of a lower edge of the display can thus also be adjusted as required by the display being more or less unwound from the display shaft. The unwound state can also be referred to as the operating state or operating position of the display. In addition, the unwound state can also be referred to as a state in which the display is exposed, extended, stretched, or unrolled.

According to a further preferred development of the device, the display shaft is designed as a hollow shaft and surrounds a shaft axis, with the clamping element or elements being arranged between the display shaft and the shaft axis. The clamping elements are coupled to the display shaft on the one hand and to the shaft axis on the other hand and are set up for this purpose. The clamping elements can thus be arranged in a particularly space-saving manner within the display shaft and do not add to the thickness or diameter.

According to a further preferred development of the device, the respective clamping element is designed as a spring element, in particular as a driving spring. The display shaft has two opposite free ends relative to its direction of longitudinal extension, and the Clamping elements are preferably arranged in a respective area of the free ends. For example, three mainsprings are arranged next to one another at one free end and three further mainsprings are arranged next to one another at the other free end around the shaft axis within the display shaft. A predetermined clamping force can thus be provided on opposite sides of the display, which enables the display to be clamped reliably.

Alternatively, a single elongate clamping element can be provided, which is designed to be somewhat shorter than the display shaft itself, for example. Alternatively, four or eight clamping elements can be provided, which are preferably arranged inside the display shaft. Alternatively, however, a tensioning force on the display can also be provided from outside the display shaft.

The mainsprings act as counter-wound roller blind or leaf springs that are wound in the opposite direction to their predetermined bending direction. In this way, power springs can be provided which provide a clamping force of 10-30 N, for example. The drive springs are designed in particular to be adapted to the rigidity of the rollable display

According to a further preferred development, the device has a shielding element, for example in the form of a roller blind or a textile web, which can be wound up and down by means of a shielding shaft. The shielding shaft is coupled to the cross member so that the shielding member faces a back side of the display and covers the back side by default when the display is wound up and down. Thus, an aesthetically pleasing rear side of the display can be laminated or be shaded, for example to cover electronic connections and/or supply cables for power and data supply.

The shielding shaft and the display shaft are preferably designed to be matched to one another in such a way that the shielding element and the display can be wound up and unwound synchronously. This can be set up, for example, by means of a fixing unit to which the shielding element and the display are coupled. The fixing unit is connected, for example, to a respective bottom edge of the shielding element and the display, so that when the shielding element and the display are unwound, they are moved away from the cross member and when the shielding element and the display are wound up, they are moved toward the cross member.

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.

According to a further development, the device has a guide mechanism which is coupled to the cross member and includes a plurality of guide levers which are coupled to the display and set up to open the display when it is unwound from the display shaft and at a winding onto the display shaft. Such a lever mechanism can also be concealed and hidden by the shielding element described above, so that it is arranged between the display and the shielding element in relation to an unwound state of the display. Such a guide mechanism can be set up for manual operation. However, the guide mechanism is preferably designed to be motorized as an alternative or in addition and can be driven electrically.

According to a further preferred development, the device has a guide system with cross member guide elements which can be coupled to the vehicle roof on opposite sides in relation to the longitudinal axis. In cooperation with the cross member guide elements, the cross member is designed to be movable in a predetermined manner relative to the vehicle roof along the longitudinal axis. The cross member and the guidance system can in particular be designed in such a way that the cross member and the display arranged on it can be moved from the very back to the very front of the vehicle roof. The display can thus be provided for the back seat of a motor vehicle or can also be moved further forward by means of the cross member, so that front vehicle passengers can also observe the display and the entertainment program output by it. Such a foremost setting is also suitable, for example, for autonomously driving motor vehicles in which vehicle passengers do not have to drive the motor vehicle themselves and can devote themselves to the entertainment program on the display.

The cross member and the display arranged thereon can be designed in such a way that they run along a section of the Vehicle roof, for example in the front area or in the rear area, are movable. Preferably, the cross member can be moved completely, so that it can be moved along the largest possible area below the vehicle roof. A partial or complete movability of the cross member below the vehicle roof can contribute to a particular increase in comfort of the motor vehicle. This can be particularly comfortable in connection with a cover system with a transparent panorama roof. For example, when not required, the display can be rolled up and stowed in or on the cross member and moved with it to a rear area of the motor vehicle, so that a particularly large view through the vehicle roof is released without an interrupting cross member. Alternatively, the cross member can not be designed to be movable and can be stationary coupled to the vehicle roof. Thus, the display can have a fixed position in or on the vehicle roof or can be set up to be displaceable with the cross member.

In addition, according to a further preferred development, the device can have a further display which, based on a longitudinal extension of the cross member, is coupled to the cross member at a distance from the rollable display.

The further display can be designed as a rigid display. However, the further display is preferably also designed as a further rollable display in order to be able to be stowed away in a particularly space-saving manner and at the same time to allow a particularly large view through a transparent cover or vehicle roof. Compared to a rigid display, which is folded up when not in use and then usually stowed away horizontally, a display that can be rolled up can be a particularly large one Gain in visibility can be achieved in the direction of the vehicle's longitudinal axis. Among other things, this can amount to half the screen height, so that, for example, with a 300 mm high rigid display, a clear view of 100-150 mm can be achieved.

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 to the front or to the very back in the motor vehicle.

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 such that it can be raised or extended and/or be designed to be stationary with a roof body and/or movable relative to it.

Due to the fact that the vehicle roof comprises an embodiment of the device, features and are described Properties of the device 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. By means of the device, for example, a relatively large screen can be stowed in a relatively small installation space. Compared to a conventional, rigid screen, headroom can be increased in the various positions. In addition, panels or a sunroof can be made smaller on an underside or inside of the vehicle roof. In addition, a view through a transparent vehicle roof can be increased. A display position below the vehicle roof can be fixed or moveable. This means that a tidy design without a visible display can be implemented in a very small space.

Exemplary embodiments of the invention are explained in more detail below with reference to the schematic drawings. Show it:

Elements of the same construction or function are identified with the same reference symbols across the figures. For the sake of clarity where appropriate, not all of the elements shown are marked 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 through the drawn xy plane is spanned and 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 tucked up.

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 obscures the 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, for example, is half the length or height of the rigid display 12 corresponds. 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 . In relation to a direction in which the display shaft 14 extends longitudinally, three drive springs 17 are arranged at opposite free ends in each case. 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 addition, further kinematic components are illustrated in FIGS. 12-16, which for example control an extension movement of the scrollable display 11 . 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 away from the crossbeam 13 by means of the guide mechanism 20 and when the shielding element 19 and the display 11 are wound up 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 lateral privacy screen on opposite sides of the rollable display 11 as laterally folding panels. Correspondingly, a tensioned state of the unwound shielding element 19, as illustrated in FIG.

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

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 are arranged, respectively. 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 on the one hand pivotably coupled to the turnstile 25 or the lever mechanism 26 and on the other hand pivotably coupled to the second guide lever 22, which can also be designed as a screen element (see Figure 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 result in a particularly space-saving folding of the Contribute management mechanism 20 and stowing 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. A rotation axis R3 of the turnstile 25 is formed or arranged between the two pivot axes S1 and S2. 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 FIGS. 24-27 enables an even more space-saving arrangement of the Displays 11 in or on the cross member 13 in comparison 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 partially or completely along the lower edge 111 with the rollable Display 11 to be paired. 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 FIGS. 12-16, the shielding element 19 can also be unwound from its shielding shaft 18 by means of the guide mechanism 20 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, rollable display 11 and the second, rigid display 12. The displays 11 and 12 can accordingly be tilted in relation to a horizontal, first plane EA1 and in relation to a vertical, second plane EA2 or be inclined (see Figures 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 cross member 13 with retracted displays 11 and 12 in one 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.

FIGS. 39 and 40 show the kinematic components for folding the second, rigid display 12 in and out and for tilting it in lateral sectional views perpendicular to the longitudinal axis L. In FIG Display 12 is folded up or folded in, and in FIG. 40 the second display 12 is partly or completely folded down or on display. 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 associated with the first display 11, 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 Al of the first display 11 and the first axis A2 of the second display 12 can be adjusted so that they are each in one enclose an angle of less than 90° with the longitudinal axis L in the issued 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 so that in a set state they enclose an angle greater than 0° with the first plane EA1 (see FIGS. 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 displays 11 and 12 can thus be stowed away 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 is coupled to the second guide lever 22 and thus, together with the first guide lever 21, specifies a guided movement of the second guide lever 22 when the rollable display 11 is opened and closed (see figures 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 moves from a set state in which the lower edge 121 of the second display 12 is aligned along an output 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.

By means of the described cross member couplings 31, 32, 33 and the associated pivot axes S6-S9 can previously described inclinations of the second display 12 can be set up reliably and stably. 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 first, rollable display 11 at the lower edge 111 and comprises a fixing bar 42, which extends along the lower edge 111 of the display 11 and is set up to be guided by the guide mechanism 20 when the display 11 is unwound from the cross member 13 to be moved away and to be moved towards 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 in particular as a film element, for example as a PET film, designed and serves, among other things, to protect the display 11 and the 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). Figure 44 shows schematically a 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 is also flexible by means of a coupling interface 46 and a Circuit unit 47 is coupled in terms of signals to the scrollable display 11 and provides 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 coupled to the fixing bar 42 or the shielding element 19 and the carrier layer 41 on the underside 421 in order to conceal the coupling positions of these elements in an aesthetically pleasing manner. 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 assigned to the first display 11 and the second supply cable 52 to the second display 12 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 cable 51 and

52 each form sheathed energy chains that have coupling structures 58 which, in cooperation with cable guides 57, provide a stable, reliable and allow the supply cables 51, 52 to be routed with little noise. 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 routed over one another, a partition is provided in the housing 54 between the supply cables 51, 52, for example, which forms a floor for the upper supply 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 coupled to it and adapted to deflect the supply cable 51, 52 and align along the longitudinal axis L and into the Cable guides 57 initiate. 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. FIG. 52 illustrates the possible movements of the U-shaped change in direction of the two supply cables 51, 52 when the crossbeam 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 sloping storage of the umbilicals 51, 52 within the housing 54 allows for useful storage and also a transfer of the respective supply cables 51, 52 to the common plane EA1 outside the housing 54, so that the supply cables 51, 52 can be guided in the cable guides 57 at the same height. 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, in which the supply cables 51, 52 each have an uncoated section 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 of 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 exercises. 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 tensioning element 593 can provide a torque or a tensile force which acts on the two tensioning 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 supply cables 51, 52 can be extended to 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 cm.

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, for example, at the very back in the area of the rear of the vehicle below of the vehicle roof 2 is stowed. 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 to a guide carriage 64 which is arranged in a respective guide channel of the associated guide rail 61 .

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 guidance system 60 are arranged in the vehicle roof 2 in a manner coordinated with one another.

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 one Connection component for the other 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 FIGS. 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 scrollable display 11, which is associated with a set state of the foldable screen unit 70, the fourth screen element 74 closes the housing 131 of the cross member 13 on a bottom, so that all other components of the Veneering unit 70 are hidden in the housing 131 of the cross member 13 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 is 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. Thus, in particular, the second and third facing elements 72 and 73 can implement 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 facing element 71 and the second facing elements 72 connected thereto are particularly suited to reliable unfolding and compact folding of the

Blinding unit 70, a stretching and catching up of the display 11 by means of the guide mechanism 20 and/or a predetermined slanting of the extended and/or retracted display 11 by means of the slanting mechanism 30 is adapted.
