Description

Device for operating a screen assembly of a vehicle roof and vehicle roof for a motor vehicle

Technical Field

The present invention relates to an apparatus for operating a screen assembly of a vehicle roof. The invention also relates to a roof for a motor vehicle having such a device.

Background

Some motor vehicles have screen assemblies that can provide entertainment on demand and help to increase the comfort of the motor vehicle. Such a screen assembly is provided with a kinematic solution, if necessary, which enables folding and unfolding of the screen assembly when required. In this case, it is a challenge to achieve a space-saving and cost-effective arrangement of such entertainment electronics and to contribute to the comfort of the motor vehicle.

Disclosure of Invention

The object on which the invention is based is to provide a device for operating a screen assembly of a vehicle roof, which device can be stored in a space-saving manner and can contribute to the comfort of the motor vehicle.

This object is achieved by the features of the independent claims. Advantageous embodiments are given in the dependent claims.

The device according to the invention for operating a screen assembly of a vehicle roof comprises a transverse carrier which is configured to be coupled to the vehicle roof such that the transverse carrier extends essentially transversely to the longitudinal axis of the vehicle roof. The device further comprises a display coupled to the transverse carrier and a guide system having a transverse carrier guide element which can be coupled to the vehicle roof on opposite sides with respect to the longitudinal axis. The transverse carrier and the transverse carrier guide element are coupled to one another in such a way that the transverse carrier can be displaced in a predefined manner along the longitudinal axis relative to the vehicle roof in conjunction with the transverse carrier guide element.

With the described device, a screen assembly for a vehicle roof can be realized, which has a movable transverse carrier and a display coupled thereto, which can be constructed particularly space-saving and can contribute to an increased comfort level of the motor vehicle. The controlled displaceability of the transverse carrier, which is provided in a predetermined manner by the guide system, can be used to facilitate a larger interior head space for the vehicle occupants. Furthermore, if the roof is configured transparently or has a transparent roof element, the device enables increased visibility through the roof.

The display is preferably configured as a rollable display and can be rolled up and unrolled by means of a display shaft which is coupled to or arranged on or integrated in the transverse carrier. The rollable display is implemented as an OLED display, for example. Alternatively, the rollable display is configured as a Micro-LED display or an electronic paper display.

Alternatively, the display may be implemented as a rigid plate-like display. Such rigid displays can be unfolded and folded by means of a lever mechanism, which is coupled side by side with the transverse carrier. Alternatively, two displays may be provided, both of which are configured to be rollable or rigid, or one of which is configured to be rollable and the other to be rigid. By means of the rollable display, the space requirement can be kept low compared to a rigid display, and in particular in the parking position of the display, a larger in-vehicle head space can be facilitated for the vehicle occupants.

According to one embodiment of the device, the guide system is configured in coordination with the vehicle roof such that the transverse carrier can be moved along the longitudinal axis along a path section corresponding to at least one quarter of the length of the vehicle roof. The guidance system is coordinated, for example, as follows: for a vehicle roof provided, the guide system enables the greatest possible mobility of the transverse carrier. The transverse carrier may thus be movable between a rear region and a front region of the roof.

In connection with the present description, terms such as "upper", "lower", "front", "rear", "upper", "lower" and "horizontal" and "vertical" refer to a motor vehicle having a roof and equipment arranged thereon, depending on the direction or orientation of the motor vehicle ready for operation. Thus, the lower edge of the display faces the vehicle interior space in the unreeled state. The usual direction of travel is directed forwards, whereas the vehicle tail is arranged behind.

According to one preferred embodiment of the device, the transverse carrier guide element is configured as a guide rail and a guide slide, which is coupled to the transverse carrier on opposite sides with respect to the longitudinal axis, such that the guide slide engages into an associated guide channel of the respective guide rail and couples the transverse carrier to the guide rail, such that the transverse carrier can be slidingly moved along the guide channel.

According to a further embodiment, the guide system comprises an electric drive unit which is coupled to the associated guide slide by means of a corresponding drive cable, so that the guide slide can be actuated by means of the drive unit and the transverse carrier can be moved electrically along the longitudinal axis. Alternatively or additionally, a manual displacement of the transverse carrier may be provided.

The roof for a motor vehicle according to the invention comprises a roof element which is arranged to be coupled to a roof body of the motor vehicle. The vehicle roof according to the invention also comprises one of the aforementioned embodiments of the device for operating the screen assembly, which device is coupled to the roof element on the side of the roof element facing the vehicle interior. The device can be connected directly or indirectly to the roof element by means of a transverse carrier. The transverse carrier can be coupled to the vehicle roof as a stationary transverse bar or can be arranged to be movable relative to the vehicle roof. The transverse carrier and the display arranged thereon or integrated therein can thus be displaced in a predefined manner along the longitudinal axis under the vehicle roof and, for example, to the forefront or rearmost part in the motor vehicle.

The roof element is realized, for example, as a cover system with a glass cover or as a panoramic glass roof. Alternatively, the roof element may also form an opaque roof skin of the vehicle roof. The roof element may be arranged to be able to be raised or extended and/or be constructed in a fixed position to the roof body and/or movable relative thereto.

As the roof includes one embodiment of the apparatus, the described features and characteristics of the apparatus are also disclosed for the roof, and vice versa.

With the described device, the screen assembly for a vehicle roof can be actuated or operated over a relatively large travel path. The display position under the roof can be adjusted in a desired manner by means of the movement of the transverse carrier. The lateral carrier and the display or displays are moved forward all the way to the front seat, which may be convenient, especially in an autopilot vehicle. By means of the guiding system, a safe and controlled movement of the transverse carriers can be achieved.

One or more displays are mounted on or integrated in the lateral carrier in a self-supporting manner (including associated drive and guide mechanisms) and can be moved left and right guided by rails about the longitudinal axis. No additional components (especially not in the center of the vehicle) are required, so that the described device and guide system enable particularly large visibility up through the roof of the vehicle without components obstructing the view. Furthermore, the available space provision for the vehicle occupants in the motor vehicle can thus be enlarged.

Detailed Description

Elements of the same construction or function are labeled with the same reference numerals across the figures. For purposes of clarity, not all of the elements illustrated in the figures are labeled with a reference numeral if necessary.

Fig. 1 shows schematically in a perspective view a roof 2 of a motor vehicle 1, which roof comprises a roof element, a cover system or a cover 4, which closes a roof opening in the roof 2. The cover 4 is, for example, a fixed glass element which is not movable relative to the vehicle roof 2. Alternatively, the cover 4 is movable relative to the roof 2 to selectively release and close a roof opening in the roof 2. The roof 2 may also be provided without the cover 4 and may be provided with a roof skin without a slot, for example a foldable or collapsible convertible roof which can be accommodated in the rear region of the motor vehicle 1. Furthermore, the roof 2 can also be constructed as a convertible top with the cover 4, wherein the cover 4 is configured such that it can be folded together or folded.

Below the roof 2, a transverse carrier 13 is arranged, which is configured to be movable about the longitudinal axis L. The transverse carrier 13 implements a bearable beam or rail which is coupled indirectly or directly to the roof 2 and/or the cover 4.

In connection with the present description, terms such as "upper", "lower", "front", "rear", "upper", "lower" and "horizontal" and "vertical" denote a motor vehicle having a roof 2 according to the direction or orientation of the motor vehicle 1 ready for operation, as it is illustrated in fig. 1. Thus, the horizontal plane is spanned by the drawn xy plane and oriented perpendicular to the drawn z-direction representing the vertical line. The longitudinal axis L corresponds to the vehicle longitudinal axis, and the drawn arrow direction indicates the usual forward travel direction. The vehicle tail is arranged or constructed behind. The transverse carrier 13 is thus arranged below and/or in the roof 2 and faces the vehicle interior of the motor vehicle 1.

As will be explained with reference to fig. 2 to 68 below, the different devices 10, 20, 30, 40, 50, 60 and 70 enable convenient operation, orientation and decoration of a screen assembly coupled with and arranged on and/or integrated in the transverse carrier 13. Devices 10 and/or 20 and/or 30 and/or 40 and/or 50 and/or 60 particularly advantageously co-operate, but may also be provided separately to provide the respective functionality.

By means of the device 10 to 70, a screen assembly for the vehicle roof 2 with at least one display 11, 12 can be realized, which can be constructed particularly space-saving and can contribute to an increased comfort of the motor vehicle 1.

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

According to fig. 2, the cover 4 is preferably configured as a transparent roof element which allows visibility through the roof 2. The cover 4 is, for example, formed as transparent glass and forms a panoramic roof, which is fixedly connected to the roof body 3 of the motor vehicle 1. In fig. 2, the device 10 is arranged in the rear or rear region of the roof 2, or is moved backwards and received.

The device 10 comprises a rollable display 11 which can be rolled up and unrolled by means of a display shaft 14 and which is coupled to a transverse carrier 13. The display shaft 14 is coupled with the transverse carrier 13 by means of a shaft attachment 16 (see fig. 10-13). The transverse carrier 13 is coupled to the vehicle roof 2 such that it extends essentially transversely to the longitudinal axis L. The main or longitudinal direction of extension of the transverse carrier 13 thus essentially leads from one side of the roof 2 to the opposite side of the roof 2.

The rollable display 11 is realized in particular as an OLED display and is also referred to as a first display 11 in the following description if necessary. The rollable display 11 can be configured as a flexible screen, fully or partially rollable or bendable. In addition to the first display 11, the device 10 has a further display 12 which is coupled to the transverse carrier 13 in a spaced-apart manner from the first display 11 with respect to the longitudinal extension direction of the transverse carrier 13. The further display 12 is configured as a rigid display and is also referred to as a second display 12 in the following description if necessary.

In this case, it is pointed out that the device 10 according to a preferred embodiment comprises two rollable displays, which are coupled side by side to the transverse carrier 13 or integrated therein, instead of one rollable display and one rigid display 11, 12. However, for descriptive reasons, the advantages of configuring the first display 11 to be rollable are described or illustrated in connection with the rigid second display 12.

Fig. 3 shows the vehicle roof 2 without the transparent cover 4, in which the transverse carrier 13 is moved completely rearward and the first and second displays 11, 12 are retracted or inserted. Since the first display 11 represents a rollable display, the illustrated rest or park position corresponds to a rolled state in which the rollable display is arranged at least largely around the display axis 14. This rolled state may also be referred to as a resting state of the first display 11. In addition, this wound state may also be referred to as a state in which the first display 11 is put in, retracted, clamped, rolled in, or retracted.

Since the second display 12 represents a rigid display, the illustrated rest or parking position corresponds to a folded state in which the rigid display is folded up and extends essentially along the roof 2 or the cover 4. This collapsed state may also be referred to as a resting state of the second display 12. In addition, the folded state may also be referred to as a state in which the second display 12 is put in, retracted, folded up, or retracted.

The middle position set by the following way is illustrated in fig. 4: the transverse carrier 13 is moved forward until the desired position under the roof 2 or the cover 4 is reached. Furthermore, the two displays 11 and 12 are shown in their respective put-out states in which they are ready to run for outputting an entertainment item.

The set-out state of the first display 11 may also be referred to as an operational state. In addition, the set-out state may also be referred to as a state in which the first display 11 is extended, expanded, unwound or unwound. The set-out state of the second display 12 may also be referred to as an operational state. In addition, this set-out state may also be referred to as a state in which the swingable second display 12 is unfolded, folded down, or extended.

The displays 11 and 12 are oriented such that, with respect to the extended state ready for operation, their respective luminous front sides are oriented in the direction toward the rear of the vehicle. With respect to the drawn longitudinal axis L, the device 10 has a rollable display 11 on the left side of the transverse carrier 13 and a rigid display 12 on the right side. Alternative arrangements are possible.

Fig. 5 shows a further perspective view of the device 10, in which the transverse carrier 13 is moved completely forward with respect to the longitudinal axis L and the indicated travel direction. Furthermore, both displays 11 and 12 are ready for output in their respective operating states. Such a foremost position of the transverse carrier 13 is for example useful if the motor vehicle 1 is configured as an autonomous vehicle and automated driving is enabled. Furthermore, such a recreation position of the displays 11, 12 can also be predefined if the motor vehicle 1 is, for example, parked for driving rest.

The mobility of the transverse carriers 13 is provided by means of the guide system 60 and, in this connection, reference is made in particular to the description below with respect to fig. 64 to 68.

In fig. 6, the protruding displays 11 and 12 are shown at the movable transverse carrier 13 in a view from obliquely behind. Fig. 7 shows respective views of the extended displays 11 and 12 in a view from above, wherein the transverse carrier 13 obscures the view to the displays 11, 12.

In fig. 8, the retracted displays 11 and 12 at the movable transverse carrier 13 are shown in a view from obliquely behind. Fig. 9 shows the respective views of the retracted displays 11 and 12 in a view from above. The advantage of the rollable display 11 is visible, in particular on the basis of fig. 9, in that the rollable display 11 can be accommodated in a particularly space-saving manner and does not protrude beyond the transverse carrier 13 in the x-direction or in the direction of the longitudinal axis L. Thus, a particularly large visibility gain through the cover 4 can be provided, which corresponds to, for example, half the length or height of the rigid display 12. Thus, the rollable display 11 facilitates a screen assembly that enables improved visibility and provides installation space advantages over a deployable rigid display.

Fig. 10 and 11 show one embodiment of a display shaft 14 on which the rollable display 11 is wound or from which the rollable display 11 is unwound. The display shaft 14 is cylindrical and is configured rotationally symmetrically. The display shaft 14 is configured as a hollow shaft and surrounds a shaft center 15. Shaft attachment 16 is disposed on opposite sides of display shaft 14 and is coupled with hub 15.

A plurality of clamping elements in the form of drive springs 17 are arranged between the display shaft 14 and the spindle 15. With respect to the longitudinal extension of the display shaft 14, three drive springs 17 are arranged on the opposite free ends, respectively. The drive spring 17 is correspondingly coupled to the display shaft 14 on the one hand and to the axle center 15 on the other hand, and is provided to tension the display 11 in a predetermined manner when unwinding from the display shaft 14 and when winding onto the display shaft 14. The drive spring 17 forms a preferred variant of a built-in spring element which contributes to: the rollable display 11 can be operated and housed in a small installation space, and a useful force is provided to tighten the rollable display 11.

The rollable display 11 and the display shaft 14 are in particular configured in coordination with one another such that they together with respect to the rolled state and a radial direction transverse to the longitudinal extension direction of the display shaft 14 have a diameter in the range of 40 to 100 mm.

Fig. 12 shows the device 10 with the transverse carrier 13 and the display shaft 14 in a lateral partial sectional view. The transverse carrier 13 has a housing 131 in which the display shaft 14 is arranged. Accordingly, the rollable display 11 can be disposed in the housing 131 in a hidden manner in a state of being wound on the display shaft 14. Fig. 12 shows the rollable display 11 in an extended state. The retracted state of the rollable display 11 is shown in fig. 13.

Further kinematic components are also illustrated in fig. 12-16, which control, for example, the extending movement of the rollable display 11. The device 20 capable of achieving this is also referred to as a guide mechanism 20 and is described below in connection with fig. 17-27. In addition, the apparatus 40 and its elements are also illustrated in fig. 12-16. The device 40 is also referred to as a stationary unit 40 and in this regard reference is made in particular to fig. 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 foldable and unfoldable finish to the display 11. The cover unit 70 is described below, particularly in connection with fig. 69-75.

The device 10 further comprises a shielding element 19 (for example in the form of a roller blind) which can be wound and unwound by means of a shielding shaft 18. The shielding shaft 18 is coupled with the transverse carrier 13 and is arranged in the housing 131 like the display shaft 14. The shielding element 19 is associated with the back side 112 of the rollable display 11 such that it covers the back side 112 in a predefined manner when the first display 11 is wound and unwound.

The shielding element 19 is coupled on the one hand at the upper end with the shielding shaft 18 and on the other hand at the lower end with the fixing unit 40. The same applies to the rollable display 11, which is coupled on the one hand at the upper end to the display shaft 14 and on the other hand at the lower end to the fixing unit 40 (see fig. 16). The fixing unit 40 is moved away from the transverse carrier 13 by means of the guide mechanism 20 when unwinding the shielding element 19 and the rollable display 11 and towards the transverse carrier 13 when winding the shielding element 19 and the display 11. The shielding shaft 18 and the display shaft 14 are configured in coordination with each other such that the shielding element 19 and the display 11 can be wound and unwound synchronously.

Fig. 14 and 15 show, similarly to fig. 12 and 13, the extended state and the retracted state of the first display 11 which can be curled, focusing on the kinematic components of the guide mechanism 20, without showing the first display 11 and the shielding element 19. The guide mechanism 20 enables a reliable unwinding and stable unwinding 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 in particular configured as a central drive with an electric motor.

According to fig. 12, some guide levers 22, 23 are also configured as lateral cover elements 72, 73 or are coupled thereto in order to form a satisfactory lateral closure or visual protection for unreeled display 11. In particular, the illustrated form of such a spacer element can facilitate a convenient visual protection and reliable operation of the guide mechanism 20. The shielding element 19 forms a rollable visual protection which in the extended state conceals the wiring and/or electronic control components of the rollable display 11. The guide levers 22 and 23 respectively serve as lateral visual protectors for the lateral foldable partition plates formed on opposite sides of the rollable display 11. The tensioned state of the unwound display 11, as illustrated in fig. 12, is established in particular by the drive spring 17 in the display shaft 14. Accordingly, the tensioned state of the unwound shielding element 19, as illustrated in fig. 12, can be established by a spring element in the visual protection shaft or shielding shaft 18.

Fig. 17-27 show an embodiment of the vehicle roof 2 with the device 10 and the guide mechanism 20 for controlled setting out and setting in of the rollable display 11 in different views. Fig. 17 to 21 show in perspective views the different positions and states of the device 10 and of the guide mechanism 20 for operating the screen assembly. Fig. 22-27 show an embodiment of the guide mechanism 20 in detail.

For clarity, only the rollable display 11 is illustrated in fig. 17-27, as long as it is visible. Thus, the guide mechanism 20 is described in connection with a rollable display 11. However, the other, second display 12 can preferably be arranged on the transverse carrier 13 as a further rollable display alongside the rollable first display 11.

Fig. 17 shows the device 10 in a parking position, in which the device is stowed in 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, in which the display 11 is further retracted or rolled in.

Fig. 19 shows the device 10 according to fig. 18 in a first intermediate position, in which the display 11 is extended or expanded.

Fig. 20 shows the device 10 in another position in which the transverse carrier 13 is moved completely forward and the display 11 is retracted or rolled in.

Fig. 21 shows the device 10 according to fig. 20 in a foremost position, in which the display 11 is extended or expanded.

The extension or unwinding and the re-retraction or clamping is effected by means of a guide mechanism 20, which can be configured according to fig. 22-27. Fig. 22 and 23 investigate the guiding mechanism 20, which comprises a turnstile 25. An alternative embodiment of the guide mechanism 20 is shown in fig. 24-27, according to which the guide mechanism 20 has a lever actuator 26.

The guide means 20 are each coupled to the transverse carrier 13 and comprise a plurality of guide levers 21, 22, 23 which are coupled to the rollable display 11 and are arranged to hold the display open when unwound from the display shaft 14 and to clamp the display 11 when wound onto the display shaft 14. A first guide lever 21, a second guide lever 22, and a third guide lever 23 are disposed with respect to the right and left sides of the display 11, respectively. Therefore, in the following, mainly one side of the guiding mechanism 20 is described, wherein the characteristics can be transferred to the other side accordingly. If desired, the differences will be pointed out with reference to the right and left sides of the guide mechanism 20 or the rollable display 11.

The first guide lever 21 is coupled pivotably on the one hand to the turnstile 25 or the lever actuator 26 and on the other hand to the second guide lever 22, which can also be configured specifically as a spacer element (see fig. 12). On the right, the coupling position of the first guide lever 21 to the turnstile 25 or the lever actuator 26 forms a first pivot axis S1. On the left, the coupling position of the first guide lever 21 to the turnstile 25 or the lever actuator 26 forms the second pivot axis S2.

The second guide lever 22 is coupled pivotably on the one hand with respect to the transverse carrier 13 and on the other hand with the third guide lever 23. The coupling of the second guide lever 22 to the transverse carrier 13 can be provided indirectly or directly. The third guide lever 23 is coupled to the second guide lever 22 in a pivotable manner, on the one hand, and to the fixing unit 40 in a pivotable manner, on the other hand.

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

The first and second guide levers 21 and 22 are configured as elongate bending guide rods in terms of their shape, while the third guide lever 23 is configured linearly. Such a preferred arrangement can facilitate particularly space-saving folding of the guide mechanism 20 and stowing of the rollable display 11. The guide levers 21, 22, 23 can be designed in particular as stable and narrow metal parts, in order to enable a reliable unwinding and unfolding of the display 11 and, furthermore, to be folded and stored in a space-saving manner. Alternatively, one or more of the guide levers 21, 22, 23 may be constructed as plastic parts.

The guide mechanism 20 is each configured as a scissor mechanism, 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 a scissor mechanism with a turnstile 25, the pivot axes S1 and S2 can be guided up and down with respect to one another, as shown in fig. 22 and 23. Fig. 22 shows the retracted or folded state of the scissor mechanism, in which the display 11 is rolled up and the guide levers 21, 22, 23 are received in the folded position. In this state, the second swing axis S2 is arranged above the first swing axis S1 with respect to the vertical line. An axis of rotation 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 configuration of the scissors mechanism according to fig. 22, in which the display 11 is expanded and the guide levers 21, 22, 23 are oriented in the straightened position. Thus, in the retracted state and in the extended state, the respective one of the swing axes S1, S2 is arranged above the other swing axis and the rotation axis R3 of the turnstile 25.

The guide mechanism 20 according to fig. 24 to 27 with the lever actuator 26 in the form of a scissor mechanism enables a more space-saving arrangement of the display 11 in or on the transverse carrier 13 than in the embodiment with the turnstile 25. The lever actuator 26 comprises two gear elements 27, 28, which are coupled on the one hand to the drive unit 24 and on the other hand to the first guide lever 21. The first gear element 27 is rotatable about a first rotational axis R1, while the second gear element 28 is rotatable about a second rotational axis R2. The gear elements 27 and 28 mesh with each other in their tooth structure, so that only one gear element can be driven by the drive unit 24 in order to also move the respective other side of the guide rods 21, 22, 23. Alternatively, the two gear elements 27, 28 may also be driven by the drive unit 24, and furthermore, embodiments are also possible in which the gear elements 27, 28 do not touch each other. By means of the drive unit 24, the rotation of the gear elements 27, 28 of the lever actuator 26 and thus the pivoting of the guide levers 21, 22, 23 and the winding or unwinding of the rollable display 11 can be initiated.

Fig. 24 shows the retracted or folded state of the scissor mechanism with lever actuator 26 in which the display 11 is rolled up. In this state, the two pivot axes S1 and S2 are arranged at approximately the same height with respect to the vertical line and above the rotational axes R1 and R2 of the gear elements 27 and 28. Thus, the fixing unit 40 coupled with the rollable display 11 at the lower edge 111 thereof can be moved closer to the lower side of the driving unit 24 than in the embodiment with the turnstile 25. The fixing unit 40 can be coupled with 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 accommodated particularly flat on the underside of the roof 2 and can contribute to a larger in-vehicle head space for vehicle occupants.

Fig. 25 shows the extended or unfolded state of the guide mechanism 20 in the configuration of the scissors mechanism according to fig. 24, in which the two pivot axes S1 and S2 are arranged approximately at the level of the rotation axes R1 and R2 or slightly below these rotation axes.

The guide levers 21, 22, 23 are coupled on the one hand with the drive unit 24 and on the other hand with a fixing unit 40 which is coupled with the rollable display 11 along its lower edge 111. The fixing unit 40 is thus moved by means of the guide levers 21, 22, 23 towards the transverse carrier 13 when the display 11 is wound. As previously described with reference to fig. 12-16, the shielding element 19 can also be unwound from or wound onto its shielding shaft 18 by means of the guide mechanism 20.

Fig. 26 and 27 show the guide mechanism 20 with the lever actuator 26 in a perspective view in the retracted state according to fig. 24 and in the extended state according to fig. 25, respectively. Furthermore, components of the guiding system 60 are illustrated which enable the movability of the transverse carriers 13. In this regard, reference is made to the following description of FIGS. 64-68.

The guide means 20 each realize a space-saving and reliable guide link for the rollable display 11. The guide mechanism 20 is particularly configured such that continuous extension and retraction of the rollable display 11 is possible, thereby enabling a desired intermediate position to be set in which the rollable display 11 is not fully retracted or extended. Thus, for example, the lower edge 111 of the rollable display 11 can be set to a desired height of the vehicle interior space. Alternatively, the guide mechanism 20 may also provide a plurality of predetermined intermediate positions, so that the display 11 can be extended or retracted stepwise. Alternatively, the guide mechanism 20 can also be configured such that the display 11 can only be fully retracted or extended.

Fig. 28-42 show the device 30 in different views, which device is also referred to as a tilting mechanism 30 in the following. The tilting mechanism 30 enables a dual tilt position of the first display 11, which is capable of being rolled, and the second display 12, which is rigid. The displays 11 and 12 can thus be tilted or inclined specifically with respect to the horizontal first plane EA1 and with respect to the vertical second plane EA2 (see fig. 33 and 35).

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

Fig. 29 shows the intermediate position of the transverse carrier 13 with the retracted displays 11 and 12 in a perspective view. Fig. 30 shows the roof 2 according to fig. 29 in a top view.

Fig. 31 shows the intermediate position of the transverse carrier 13 with the extended displays 11 and 12 in a perspective view. Fig. 32 shows the roof 2 according to fig. 31 in a top view.

Fig. 33 shows the foremost or front position of the transverse carrier 13 with the extended displays 11 and 12 in top view. Fig. 34 shows the roof 2 according to fig. 33 in a top view with the displays 11 and 12 retracted.

Fig. 35 shows the retracted displays 11 and 12 in a sectional view with a rearward viewing direction along the second plane EA 2. Fig. 36 shows the roof 2 according to fig. 35 in a perspective view.

Fig. 37 and 38 show the vehicle roof 2 according to fig. 35 and 36 with the extended displays 11 and 12, with a rearward viewing direction.

Fig. 38A and 38B schematically illustrate kinematic components for expanding and collapsing and tilting the rigid second display 12 in the expanded and collapsed positions.

Fig. 39 and 40 show the kinematic components of the second display 12 for unfolding and folding and tilting rigidity in a lateral sectional view perpendicular to the longitudinal axis L. The second display 12 is folded or folded upwardly in fig. 39, and the second display 12 is partially or fully folded or deployed downwardly in fig. 40. By means of the lever mechanism 37, the desired inclination of the second display 12 with respect to the vertical can be set.

Fig. 41 and 42 show the kinematic components of the first display 11 for unfolding and folding and tilting the flexible, in a sectional view along the longitudinal axis L. In fig. 41 the first display 12 is retracted or rolled in, and in fig. 42 the second display 12 is fully extended or extended.

The tilting mechanism 30 comprises a plurality of guiding elements 31-36 coupling the respective display 11 or 12 with the lateral carrier 13. The guide elements 31-33 are assigned to the second display 12 and may also be referred to as first, second and third transverse carrier couplings 31-33. To the first display 11 are assigned guide elements 34-36, which comprise a runner guide element 34, a runner rail 35 and a guide pin 36.

The guide elements 31-36 are arranged such that the respective display 11, 12 is oriented with respect to the associated lower edge 111, 121 along the first axis A1, A2 in the set-out state and along the second axis A3, A4 in the set-in state. The first axes A1, A2 are oriented in a first plane EA1 which is spanned by the longitudinal axis L and the longitudinal extension of the transverse carrier 13. The first plane EA1 corresponds to a horizontal plane. The first axis A1 of the first display 11 and the first axis A2 of the second display 12 can be set such that they each enclose an angle of less than 90 ° with the longitudinal axis L in the set-out state (see fig. 32 and 33). The smaller angle between the axis A1 or A2 and the longitudinal axis L is regarded as the enclosed angle. Thus, according to fig. 32, the angle of the upper right (toward the vehicle rear) or lower left (toward the vehicle front) with respect to the illustrated intersection of the axis A1 and the longitudinal axis L may be referred to as the enclosed angle. For the axis A2, correspondingly, the angle of the upper left (toward the front of the vehicle) or lower right (toward the rear of the vehicle) may be referred to as the enclosed angle.

The second axes A3, A4 of the displays 11, 12 are oriented in a 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 adjusted such that they enclose an angle of more than 0 ° with the first plane EA1 in the inserted state (see fig. 29, 35 and 36). Also here, the smaller angle between the axis A3 or A4 and the horizontal plane EA1 is regarded as an enclosed angle. Thus, according to fig. 35, the angle of the lower right (toward the vehicle outside) or the upper left (toward the vehicle middle) with respect to the intersection of the axis A3 and the horizontal plane EA1 (not drawn for clarity) may be referred to as the enclosed angle. For the axis A4, correspondingly, the angle of the lower left (toward the vehicle outside) or the upper right (toward the vehicle middle) may be referred to as the enclosed angle.

The displays 11 and 12 can thus each be set to have a predefined tilt position along their first axes A1, A2 in the set-out state and a predefined tilt position along their second axes A3, A4 in the set-in state.

The first axes A1 and A2 take into account the viewing direction or line of sight of a vehicle occupant, who is not usually seated centrally in front of the respective display 11, 12 in the motor vehicle 1, but is slightly offset from the display center. The displays 11 and 12 can thus be tilted in a predefined manner with respect to their luminous front sides outwards towards the respective vehicle outside, so that the line of sight corresponds essentially to the normal direction of the front side of the associated display 11, 12 (see fig. 32).

By means of the possibility of setting along the second axes A3 and A4, the displays 11 and 12 can be accommodated higher in the middle of the vehicle than in the outer regions. The displays 11 and 12 can thus be accommodated in the parking position by means of the tilting mechanism 30 such that they extend mainly along the vehicle roof 2 or the cover 4. The roof 2 and the cover 4 are not generally configured in a planar manner in a horizontal plane, but rather are configured in a predefined arch shape and are oriented higher in their center than in their side edges with respect to the state of being mounted on the motor vehicle 1. With the described tilting mechanism 30, the arched structure of the roof 2 and the cover 4 can be considered and contribute to an increased in-vehicle head space for the vehicle occupants (see fig. 35 and 36).

The tilting mechanism 30 of the first display 11 and the tilting mechanism 30 of the second display 12 are each arranged such that the respective second axis A3, A4 is predefined on the underside of the vehicle roof 2 in coordination with the position of the vehicle roof 2 and/or the cover 4 and the displays 11, 12 such that the associated displays 11, 12, in the inserted state, follow the shape of the vehicle roof 2 and/or the cover 4 along the longitudinal extension direction of the transverse carrier 13 and are inserted substantially parallel to the vehicle roof 2 and/or the cover 4.

The tilting mechanism 30 of the first display 11 comprises a slotted guide element 34 which is coupled to the transverse carrier 13 and has a slotted guide track 35 into which a guide pin 36 engages and in which the guide pin 36 can be guided in a predefined 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, the guided movement of the second guide lever 22 during the placement and insertion of the rollable display 11 is predefined (see fig. 41 and 42).

The tilting mechanism 30 of the second display 12 comprises a lever mechanism 37 which is coupled to the transverse carrier 13 and by means of which the second display 12 can be unfolded and folded. The lever mechanism 37 comprises three transverse carrier links 31, 32, 33 which are of different sizes and are configured in a pivotable manner, so that the second display 12 is moved from a mounted state in which the lower edge 121 of the second display 12 is oriented along the output axis A0 (see fig. 34). The output axis A0 is oriented perpendicular to the longitudinal axis L in the first plane EA 1. The second display 12 is thus oriented in the horizontal plane without tilting in the set parking position below the vehicle roof 2. Thus, the edges of the second display 12 are substantially parallel or perpendicular to the longitudinal axis L in the folded state. With respect to the horizontal first plane EA1, the second display 12 is tilted along the second axis A4 (see fig. 35-36).

The first transverse carrier coupling 31 couples the second display 12 swingably with the transverse carrier 13 and has a swing axis S6. The oscillation axis S6 also corresponds to the oscillation axis of the third transverse carrier coupling 33. With respect to the illustration illustrated in fig. 38A, the first transverse carrier link 31 is arranged in the left region on the rigid display 12, while the third transverse carrier link 33 is arranged in the right region on the rigid display 12. Thus, the second transverse carrier coupling 32 is arranged centrally and has three swivel axes S7, S8 and S9. The second transverse carrier coupling 32 comprises a chute lever 321 and a further lever 322. The slotted lever 321 is coupled pivotably on the one hand to the transverse carrier 13 and on the other hand to the lever 322. In addition, the lever 322 is swingably coupled with the display 12 (see fig. 40). The chute lever 321 comprises a chute into which a guide pin, for example a drive unit 24, is inserted, which guide pin drives the chute lever 321 to oscillate and cause folding or unfolding of the display 12.

The aforementioned tilting position of the second display 12 can be reliably and stably set by means of the described transverse carrier coupling 31, 32, 33 and the pivot axes S6 to S9 associated therewith. With respect to the horizontal axis, the pivot axes S6-S9 run obliquely in a predetermined manner to form the described tilted position of the second display 12.

The tilting mechanism 30 or 37 enables a transition of the second display 12 into a tilted state in which the second display 12 is oriented with a predetermined tilt position along the first axis A2 (see fig. 35-40). Furthermore, the first and second displays 11 and 12 can be set by means of their tilting mechanisms 30 such that their lower edges 111, 121 are oriented substantially horizontally (see fig. 37-38).

Fig. 43-45 show side cross-sectional views of the device 40, also referred to as the fixation unit 40. The fixing unit 40 is coupled with the rollable first display 11 at the lower edge 111 and comprises a fixing beam 42 extending along the lower edge 111 of the display 11 and arranged to move away from the transverse carrier 13 when unwinding the display 11 and towards the transverse carrier 13 when winding the display 11 by means of the guiding mechanism 20. The fixing unit 40 tightens the rollable display 11 in conjunction with the display shaft 14 and preferably also tightens the shielding element 19 in conjunction with the shielding shaft 18.

The fixing unit 40 has a carrier layer 41 coupled to the rollable display 11 at its front side 113. The carrier layer 41 is in particular configured as a film element, for example a PET film, and serves in particular to protect the display 11 and to attach it stably and reliably to the fixing beam 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 fastening beam 42 on the underside 421 in a force-locking, form-locking and/or material-locking manner.

The fastening beams 42 have a rounded contour in the respective reversal areas, in which the shielding element 19 and the carrier layer 41 are reversed, in order to be able to reliably and gently tension the respective element. The fixing beams 42 are made of, for example, aluminum or glass fiber reinforced plastic and have sufficient rigidity to achieve reliable attachment and distraction of the display 11.

Also as shielding element 19, carrier layer 41 has fastening openings 48 into or through which fastening elements 43 extend, which are constructed or arranged on underside 421 of fastening beams 42.

Preferably, the fastening elements 43 and the fastening openings 48 are configured in coordination with one another in terms of their shape and their number. For example, the fastening beams 42 are embodied as plastic molded parts integrally with fastening elements 43 each in the form of an elongated button, which form a corresponding suspension tab and are arranged equidistantly on the underside 421 (see fig. 44). Fig. 44 schematically shows a view of the fixing beam 42 from below. The fastening opening 48 is embodied in the form of a longitudinal bore, into which the fastening element 43 is introduced.

The shielding element 19 and the carrier layer 21 each have a fastening opening 48, which in its position is configured in a predetermined manner such that the respective fastening element 43 of the fastening beam 42 extends through the associated fastening opening 48 of the shielding element 19 and the associated fastening opening 48 of the carrier layer 21. As a result, a force-locking and/or form-locking connection of the shielding element 19 and the carrier layer 41 to the fastening beam 42 can be provided, alternatively or additionally the shielding element 19 and/or the carrier layer 41 can be glued to the fastening beam 42.

According to fig. 45, the carrier layer 41 and/or the shielding element 19 has, in the respective edge regions thereof coupled to the fixing beams 42, strip-shaped reinforcing elements 49, for example in the form of perforated metal strips. The respective edge regions can thus be embodied in a reinforced manner in order to establish a particularly reliable and stable coupling of the carrier layer 41 and/or the shielding element 19 to the fastening beam 42.

The mounting unit 40 also includes display electronics 44 mechanically coupled to the mounting beam 42 at an upper side 422. The display electronics 44 are also coupled to the rollable display 11 by means of the coupling interface 46 and the flexible circuit unit 47 in terms of signaling technology and provide the display 11 with predefined electronic functionalities, for example in a coordinated manner with the on-board computer of the motor vehicle 1. The coupling pressure between the circuit unit 47 and the display electronics 44 is preferably set smaller than the coupling pressure between the carrier layer 41 and the fixing beams 42. The circuit unit 47 is configured, for example, as a flexible printed circuit electronic device.

The shielding element 19 is for example configured as a textile element in the form of a roller blind or as an opaque layer in order to shield electronic and/or mechanical components on the back side 112 of the rollable display 11. Furthermore, the fastening unit 40 has a cover 45 which is coupled to the fastening beam 42 or the shielding element 19 and the carrier layer 41 on the underside 421 in order to conceal the coupling points of these elements in an aesthetically pleasing manner. Furthermore, the cover 45 has a rounded contour outwards or in the direction of the vehicle interior in order to contribute to the safety of the vehicle occupant.

Fig. 46-63 show the device 50 in different views, which device is also referred to as cable storage unit 50 in the following. The cable storage unit 50 enables reliable data supply and current supply to the rollable first display 11 and the rigid second display 12.

Fig. 46 and 47 each show the arrangement of the cable storage unit 50 in a rear region of the vehicle roof 2 in a perspective view. Alternatively, the cable storage unit 50 may be integrated in the front region of the roof 2.

Fig. 48-60 illustrate the cable storage unit 50 in different views.

Fig. 61-63 illustrate exemplary embodiments of possible tensioning schemes to keep the cable storage unit 50 supply cables 51, 52 tensioned.

The cable storage unit 50 has a first supply cable 51 and a second supply cable 52 that provide respective data and/or current to the displays 11 and 12. Thus, the first supply cable 51 may be associated with the first display 11 in terms of supply technology, while the second supply cable 52 may be associated with the second display 12 in terms of supply technology. This may include a data supply and/or a current supply. Alternatively and preferably, the data supply means and the current supply means are positioned separately from each other, such that for example a first supply cable 51 provides a respective current supply to the two displays 11 and 12, while a second supply cable 52 provides a respective data supply to the two displays 11 and 12. Separate supplies are particularly advantageous for voltage reasons and in view of electromagnetic compatibility and/or safety aspects. The supply cables 51 and 52 each form a sheathed energy chain with a coupling structure 58 which, in conjunction with the cable guide 57, enables a stable, reliable and low-noise guidance of the supply cables 51, 52. If no such energy chain sheath is useful, a 59 of unsheathed section 56 of supply cable 51, 52 is also provided.

The cable guides 57 are arranged on opposite sides of the roof 2 and enable guiding the supply cables 51, 52 from rearmost to foremost in the roof 2 in a controlled manner. In order to be able to provide such a relatively large movability of the transverse carrier 13, the supply cables 51, 52 are arranged one above the other in a housing 54 (see fig. 50-53). The housing 54 is provided for storing and releasing the supply cables 51, 52 and is integrated in the rear cross member of the roof 2. Alternatively, it may be integrated in the front cross member or the air guide of the roof 2. In order to enable the supply cables 51, 52 to be guided reliably above and below one another, a partition wall in the housing 54 is provided, for example, between the supply cables 51, 52, which partition wall is configured for the bottom of the upper supply cable 52. The bottom for the lower supply cable 51 is realized by the housing bottom.

The supply cables 51, 52 are fastened at the ends facing away from the respective display 11, 12, for example by means of a fastening hook position fastening (not shown). Starting from the fixed end, the supply cables 51, 52 run through the housing 54 and leave the housing 54 on the side associated therewith by means of the respective reverser 55. The reversing section 55 is configured with or coupled to the housing 54 and is provided to reverse the supply cables 51, 52 and orient them along the longitudinal axis L and introduce them into the cable guide 57. The reversing section 55 can be integrally formed with the housing 54 and possibly the partition wall and the cover section, in particular by means of injection molding. Through the cable guide 57, the supply cables 51, 52 reach the associated display 11, 12. Furthermore, unsheathed sections 56 of the supply cables 51, 52 are illustrated, respectively (see fig. 53).

The supply cables 51, 52 thus run in sections along the longitudinal axis L in the cable guide 57 on the respective side of the vehicle roof 2 and in sections in the housing 54, wherein the supply cables 51, 52 in the housing run in opposite directions on top of one another in the obliquely oriented planes E1 and E2 and each have a U-shaped direction switch in order to be able to provide a sufficiently long supply line. If the transverse carrier 13 is moved closer to the cable storage unit 50 or further away from it, fig. 52 illustrates a possible movement of the U-shaped directional switching section of the two supply cables 51, 52.

Fig. 56 illustrates a housing 54 that includes a first obliquely oriented plane E1 and a second obliquely oriented plane E2. For the purpose of specifying the tilt position in a targeted manner, a horizontal plane EA1 is also drawn. The first plane E1 is arranged below the second plane E2 with respect to the vertical, wherein the first supply cable 51 is assigned to the first plane E and the second supply cable 52 is assigned to the second plane E2 of the housing 54.

The inclined retention of the supply cables 51, 52 within the housing 54 enables a useful accommodation and also enables a transfer of the respective supply cables 51, 52 into a common plane EA1 outside the housing 54, so that the supply cables 51, 52 can be guided in the cable guide 57 at the same height. The torsion or tension in the transfer of the supply cables 51, 52 from their respective planes E1, E2 into the horizontal plane EA1 can be absorbed by means of the reverser 55.

The supply cables 51, 52 each have a carriage with a slide 53 which enables a low-resistance guiding of the supply cable 51, 52 within the guide channel of the associated cable guide 57 (see fig. 58-60). Supply cables 51, 52 for current and data-technology supply pass from cable guides 57 into the transverse carrier 13 and through it to the respective display 11, 12 (see fig. 54). Fig. 54 illustrates a connection in which the supply cables 51, 52 each have an unshrouded section 59 which leads to the respective display 11, 12 and can be installed in the transverse carrier 13 or its housing 131 in a space-saving manner. For reasons of clarity, the transverse carrier 13 and the displays 11, 12 arranged thereon are not shown in fig. 54.

Preferably, the cable storage unit 50 also comprises a tensioning mechanism 591, 592, 593, as shown in fig. 60-63, and which is coupled with the respective supply cable 51, 52 and applies a predetermined tensioning force to the supply cable 51, 52.

For example, such tensioning means are realized in the form of tensioning links which are coupled to opposing carriages. Alternatively or additionally, as shown in fig. 61, tensioning elements 591, 592 are provided in the housing 54 in the region of the respective U-shaped directional switches of the supply cables 51, 52, which are configured to be displaceable or stretchable and to exert a tensioned force on the respective supply cables 51, 52. Such tensioning elements 591, 592 may be implemented as, for example, tension springs or rope attachments.

Alternatively or additionally, a tension coupling between the two supply cables 51, 52 can be provided, as schematically shown in fig. 62 and 63. The two tensioning elements 591 and 592 are coupled with the associated supply cable 51, 52 and with a further tensioning element 593 which exerts a force such that the supply cable 51, 52 remains tensioned in a predetermined manner. The other tensioning element 593 may provide a torque or a pulling force that acts on both tensioning elements 591, 592.

The described tensioning scheme may help to keep noise generation when moving the supply cables 51, 52 low and furthermore enable controlled and guided extension or retraction of the supply cables 51, 52 out of or into the housing 54. Furthermore, the flexible cover of the housing 54 can be configured in coordination with the geometry of the one or more supply cables 51, 52 and contact or intersect 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 current supply to the two displays 11, 12 can be achieved, which is also provided when the transverse carrier 13 can be moved along the longitudinal axis L over the entire or the largest possible usable length below the roof 2. The supply cables 51, 52 are provided correspondingly long, so that they have a length of, for example, more than 140 cm. Such a length of the supply cables 51, 52 is associated with a corresponding mobility of the transverse carrier 13, from which it is advantageous to arrange the supply cables 51, 52 one above the other in the housing 54 in a front or rear transverse beam in the roof 2. If a small movability is provided, so that the supply cables 51, 52 should only be provided with a movable length of, for example, 50cm to 100cm, the preservation in the housing 54 can be provided in a common, in particular horizontal, plane. For example, the supply cables 51, 52 may be configured in coordination with a movable length of 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, 110cm, 120cm, 130cm, 140cm, 150cm, 160cm, 170cm, 180cm, 190cm, or 200 cm.

Fig. 64-68 show the device 60, also referred to as the guidance system 60, in different views. The guiding system 60 enables a reliable and safe guiding of the transverse carrier 13 along the longitudinal axis L and the displays 11, 12 arranged thereon.

Fig. 64 to 66 show the roof 2 and the transverse carrier 13 coupled thereto in different displacement positions in a perspective view. Fig. 64 illustrates the transverse carrier 13 in a parking position in which it is received, for example, rearmost in the region of the vehicle rear below the roof 2. Fig. 65 shows the transverse beam 13 with the displays 11, 12 folded or retracted upwards in the intermediate position. Fig. 66 shows the transverse beam 13 with the displays 11, 12 folded or retracted upwards in the front position. The transverse beam 13 can be moved in particular continuously by means of the guide system 60, so that any number of intermediate positions can be set between the foremost position and the rearmost position as desired.

Fig. 67 and 68 show the components of the guidance system 60 in corresponding perspective views. The guide system 60 has a transverse carrier guide element in the form of two guide rails 61, which are coupled or can be coupled to the vehicle roof 2 on opposite sides with respect to the longitudinal axis L. The transverse carriers 13 are each coupled on opposite sides to a guide slide 64, which is arranged in a corresponding guide channel of the associated guide rail 61.

The guide system 60 further comprises an electric drive unit 63 (in particular in the form of an electric motor) which is coupled with an associated guide slide 64 by means of a respective drive cable 62, so that the guide slide 64 can be actuated by means of the drive unit 63 and the transverse carrier 13 can be moved electrically along the longitudinal axis L. Alternatively or additionally, a manual displacement of the transverse carrier 13 can also be provided. As shown in fig. 67, the drive unit 63 may be arranged in a rear region of the roof 2 or alternatively in a front region of the roof 2. In particular, the cable storage unit 50 and the guide system 60 are arranged in coordination with one another in the vehicle roof 2.

By means of the guiding system 60, a safe and controlled guiding of the transverse carriers 13 can be constructed. The displays 11 and 12 are movable together with the transversal carrier 13 in such a way that they are arranged on the transversal carrier, and the convenient positions of the displays 11 and 12 can be adjusted to output the entertainment item. Furthermore, the large-scale movability of the transverse carrier 13 enables the release of visibility through the cover 4 without said visibility being limited in the middle of the vehicle upwards by a cross beam, rail or other sight-obstructing component. Thus, a maximum possible visibility through the roof 2 can be achieved, which is perceived as particularly pleasant, in particular in connection with a transparent panoramic roof as roof element.

Fig. 69 to 75 show the device or the cover unit 70 or parts thereof in different views. The cover unit 70 enables an optically satisfactory finish of the rollable first display 11 and covers the predefined sections in order to conceal mechanical and/or electrical attachments in particular and thereby also avoid undesired light irradiation onto the rear side 112 of the display 11.

The cover unit 70 has one first cover element 71, two second cover elements 72, two third cover elements 73, and one fourth cover element 74 (see fig. 71-75). The first cover element 71 is arranged on or in the transverse carrier 13 and coupled thereto, and an upper attachment means for the further cover elements 72-74 is realized. The fourth cover element 74 is coupled to the display 11 at its lower edge 111 and constitutes a lower terminating part. The second and third cover elements 72, 73 are each arranged on opposite sides with respect to a vertical center axis of the cover unit 70 from the first cover element 71 to the fourth cover element 74 and are connected to the first or fourth cover element 71, 74, so that the second and third cover elements 72, 73 couple the first cover element 71 to the fourth cover element 74.

The fourth cover element 74 can be embodied as the cover part 45 according to fig. 13 to 16 and 43, or alternatively be embodied in addition to this cover part. Thus, the fourth cover element 74 may be coupled, e.g., screwed, clamped, and/or glued, to the fixed beam 42 (see fig. 69-72). The cover unit 70 and in particular the fourth cover element 74 are preferably configured in accordance with the geometry and the appearance of the housing 131 of the transverse carrier 13. For example, the housing 131 and the fourth cover element 74 have the same material, the same surface structure, a coordinated edge course and/or the same arch structure, so that a uniform and particularly attractive appearance can be facilitated.

In the retracted state of the rollable display 11 (which is accompanied by the folded-in state of the foldable cover unit 70), the fourth cover element 74 closes the housing 131 of the transverse carrier 13 on the underside, so that all other components of the cover unit 70 are accommodated in a concealed manner in the housing 131 of the transverse carrier 13. The fourth cover element 74, which is closed at the bottom, is therefore preferably adapted in a predefined manner to the housing 131 of the transverse carrier 13 and can be configured identically to the housing or can be deliberately contrasted with the housing.

The cover unit 70 is coupled to the transverse carrier 13 and is arranged for being folded when wrapping the display 11 and unfolded when unwrapping the display 11 and for constructing a cover frame along the lateral edges of the display 11 in relation to the lateral edges of the display 11 (see fig. 73-75).

The second and third cover elements 72, 73 associated with each other are each coupled pivotably relative to each other by means of a hinge element 75. Correspondingly, a pivot axis S4 is provided at the coupling point between the second and third cover elements 72, 73. Furthermore, the second cover element 72 is coupled to the first cover element 71 in a pivotable manner. Accordingly, a pivot axis S3 is provided at the coupling position between the second cover element 72 and the first cover element 71. Furthermore, the third cover element 73 is coupled to the fourth cover element 74 in a pivotable manner. Accordingly, a pivot axis S5 is provided at the coupling position between the third cover element 73 and the fourth cover element 74.

In this way, the cover unit 70 can be configured in the form of a foldable and expandable cover frame which provides an aesthetically pleasing finish around the display 11 and can furthermore be folded in a space-saving manner and can be accommodated in the housing 131 of the transverse carrier 13. During folding, the two second and third cover elements 72, 73 are moved toward each other in the coupled position of the pivot axis S4 (see fig. 71 and 72). The pivot axis S4 follows a horizontal and a vertical course of movement. The pivot axis S5 follows a substantially vertical course of movement. The pivot axis S3 remains substantially stationary. If necessary, a certain movement of the pivot axes S3 and/or S5 in the vertical and/or horizontal direction is also configured in a predefined manner, for example, in order to achieve a stowing of the cover unit 70 in a predefined tilt position, as described in connection with the tilting mechanism 30 according to fig. 28 to 42.

The cover unit 70 may further comprise a fifth cover element in the form of a light shielding element, which constitutes a shielding for covering the back side 112 of the display 11. The fifth cover element is embodied in particular as the aforementioned shielding element 19, which can be wound and unwound by means of the shielding shaft 18 (see fig. 60 to 70 and 73 to 74). Alternatively, the fifth cover element may be configured as an additional element which faces the back side 112 of the display 11 and covers said back side 112 in a predefined manner when winding and unwinding the display 11.

The cover elements 71-74 are configured in a plate-like manner and are shaped in a predefined manner in relation to a transverse extension transverse to the respective thickness, in coordination with the respective installation space present. In particular, the second and third cover elements 72, 73 are configured in a predetermined manner with respect to their lateral extent in coordination with the intermediate space between the unwound display 11 and the fifth cover element or shielding element 19 (see fig. 12). The cover elements 71-74 and/or the housing 131 may be made of aluminum or plastic or have a material mixture. Furthermore, cover elements 72-74 may be implemented as textile covered components, for example, to provide a desired appearance.

Preferably, the cover unit 70 is also configured in coordination with the aforementioned devices 10-60. Thus, in particular, the second and third cover elements 72 and 73 can implement the guide levers 22 and 23 of the guide mechanism 20 (see fig. 14 and 22 to 25). Alternatively, the second and third cover elements 72, 73 and the guide levers 22, 23 may be configured as separate elements, so that the second and third cover elements 72, 73 conceal the guide levers 22, 23 in a predefined manner and provide visual protection towards the built-in guide mechanism 20. Further, the deployment of the cover unit 70 may be automatically controlled by means of the drive unit 24 of the guide mechanism 20. Alternatively or additionally, a separate drive unit may be provided for folding and unfolding the cover unit 70.

Furthermore, preferably, the cover unit 70 is adapted in terms of its shape to one or more functions of the device 10-60, as illustrated in fig. 75. Thus, the first cover element 71 has a first coupling section 76 and an opposite second coupling section 77, with respect to the respective second cover element 72 of different construction. Accordingly, the second cover element 72 has a differently configured coupling structure than the first cover element 71. The first cover element 71 also has a projection 78. The illustrated configuration of the first cover element 71 and the second cover element 72 connected thereto are in particular suitable for reliably expanding and compactly folding the cover unit 70, for expanding and retracting the display 11 by means of the guide mechanism 20 and/or for tilting the extended and/or retracted display 11 by means of the tilting mechanism 30.
