Description

Technical Field

[0001] This invention relates to a device for operating a screen assembly for a vehicle roof. The invention also relates to a vehicle roof having such a device. Background Technology

[0002] Some motor vehicles are equipped with screen assemblies that can provide entertainment on demand and contribute to improving vehicle comfort. When necessary, such screen assemblies are designed with kinematics to allow for folding and unfolding when needed. Achieving a space-saving and cost-effective arrangement of such entertainment electronics is both a challenge and a contribution to vehicle comfort. Summary of the Invention

[0003] The objective of this invention is to provide a device for operating a screen assembly for a vehicle roof that is space-saving and contributes to the comfort of the vehicle.

[0004] This task is addressed through the features of the independent claims. Advantageous extensions are given in the dependent claims.

[0005] The apparatus according to the invention for operating a screen assembly for a vehicle roof includes a lateral support member configured for coupling with the roof such that the lateral support member extends primarily transversely to the longitudinal axis of the roof. The apparatus also includes a rollable display capable of being wound and unwound via a display axis, and coupled to the lateral support member. The apparatus further includes a shielding unit coupled to the lateral support member and having a plurality of shielding elements. The shielding elements are pivotally coupled to each other and configured to be folded up when the display is wound and unfolded when the display is unwound, such that the shielding elements construct a klappbar-like shielding frame along the lateral edge of the display.

[0006] The described device enables the creation of a screen assembly for a vehicle roof with a rollable display, which can be constructed in a particularly space-saving manner and contributes to improved vehicle comfort. Compared to rigid displays, it minimizes space requirements and, especially in the display's parking position, facilitates greater headroom for vehicle passengers. Furthermore, if the roof configuration is transparent or has transparent roof elements, the device achieves increased visibility through the roof. A retractable and extendable shielding frame aids in visual protection, for example, concealing mechanical and / or electrical attachments integrated with the rollable display.

[0007] The display, for example, is an OLED display that can be rolled up to a predetermined diameter without damaging the electronics and functionality. Alternatively, the display is constructed as a Micro-LED display or an electronic paper display and is configured to be rollable.

[0008] The display is arranged around the display axis in a wound state. This wound state can also be referred to as the display's non-operating state or parking position. In addition, this wound state can also be referred to as the state in which the display is placed, retracted, clamped, wound, or pulled back.

[0009] Accordingly, in the unwound state, the display is no longer largely arranged around the display axis. The display can be completely or partially unwound from the display axis and provide an output medium for visual and auditory entertainment programs. This unwound state can also be referred to as the display's operating state or operating position. Furthermore, this unwound state can also be referred to as the state in which the display is unfolded, extended, opened, or rolled up.

[0010] According to an extension of the device, the blocking unit includes a first blocking element, two second blocking elements, two third blocking elements, and a fourth blocking element. The first blocking element is arranged on or integrated into a transverse support. The fourth blocking element is coupled to the display at its lower edge. One of the second and third blocking elements is arranged about a central axis on opposite sides from the first to the fourth blocking element, and the first and fourth blocking elements are coupled to each other. In this way, a blocking frame can be constructed using swingable blocking elements, the blocking frame itself being closed or having one or more pre-defined slots.

[0011] In conjunction with this specification, terms such as “upper,” “lower,” “front,” “rear,” “upper side,” “lower side,” and “horizontal” and “vertical” indicate, according to the direction or orientation of the motor vehicle when it is ready for operation, that the motor vehicle has a roof and equipment disposed thereon. Therefore, the lower edge of the display faces the interior space of the vehicle in the unrolled state. The common direction of travel points forward, while the rear of the vehicle is positioned rearward.

[0012] Therefore, the first shielding element can also be referred to as the upper shielding element and is particularly provided as a coupling element for attachment to a lateral support member. The fourth shielding element can also be referred to as the lower shielding element and realizes the lower termination of the device in order to conceal mechanical fasteners and / or edges, for example, in a predetermined manner. Thus, the second and third shielding elements form lateral members that are retractable and expandable and coupled to the upper and lower shielding elements.

[0013] According to an extended embodiment, the corresponding second and third blocking elements are coupled by means of corresponding hinge elements, allowing them to swing relative to each other about a swing axis. The shapes of the second and third blocking elements and the positions of the hinge elements are constructed to match the winding and unwinding of the display. In particular, the second and third blocking elements and the hinge elements are positioned such that they fold inward when the display is wound and unfold outward when the display is unwound. In other words, when the blocking unit unfolds, the opposing second and third blocking elements move away from each other, while when it unfolds, they move towards each other at least on one side. Therefore, reliable guided opening and closing movements of the blocking frame can be provided in a simple and cost-effective manner.

[0014] According to a preferred extension of the device, the shielding unit includes a fifth shielding element capable of being wound and unwound via a shielding shaft to form a shield for covering the back side of the display. The shielding shaft is coupled to and integrated, for example, into a lateral support member, such that the fifth shielding element faces the back side of the display and covers the back side in a predetermined manner during the winding and unwinding of the display. Therefore, the back side of the display can also be aesthetically decorated using the shielding unit.

[0015] The fifth shielding element is constructed, for example, in the form of a roller blind or a fabric strip and, when extended, conceals the back of the display in order to cover, for example, electronic and / or mechanical connectors and / or supply cables for supplying current or data.

[0016] Preferably, the shielding unit, shielding shaft, and display shaft are configured to match each other, allowing the fifth shielding element and the display to be wound and unwound synchronously. Preferably, the second and third shielding elements are configured to also be able to unfold and retract synchronously together. This can be achieved, for example, by means of a fixing unit, wherein the display and the shielding elements of the shielding unit are coupled to the fixing unit. The fixing unit is connected, for example, to the corresponding lower edges of the fifth shielding element and the display, such that the fixing unit moves downward away from the lateral support when the fifth shielding element and the display are unwound, and moves upward toward the lateral support when the shielding element and the display are wound.

[0017] According to another extension of the device, the second and third shielding elements are specifically constructed to match the gap between the unwound display and the unwound fifth shielding element in terms of lateral extension dimension. Here, the lateral extension dimension refers to the extension dimension along the longitudinal axis of the roof and transverse to the longitudinal extension direction of the lateral support member. The front / front side of the protruding display generally faces the rear of the vehicle, such that the lateral extension dimension refers to the direction between the rear / back side of the protruding display and the fifth shielding element.

[0018] Preferably, one or more of the shielding elements are plate-shaped, such that when they extend, the largest possible gap between the display and the fifth shielding element can be closed. Therefore, reliable visual and shading protection can be provided, achieving not only a satisfactory finish along the edges of the display but also preventing unwanted light from incident on the back of the display.

[0019] According to another extension, the device has a guiding mechanism coupled to a transverse support member and including multiple guiding levers coupled to the display and configured to open the display when unwound from the display axis and retract the display when wound back onto the display axis. Such a lever mechanism can also be hidden and covered by the aforementioned blocking element of the blocking unit, such that its unwound state with respect to the display is arranged between the display and the blocking unit. The guiding mechanism can be configured for manual operation. Preferably, the guiding mechanism is alternatively or additionally constructed to be motorized and can be electrically driven.

[0020] Furthermore, the blocking elements of the blocking unit can function as a guiding mechanism. For example, the second and third blocking elements can also be configured as guide levers of the guiding mechanism for opening the display. Alternatively, the blocking elements can be separate components attached to the guide levers and hidden from the outside. Here, the blocking elements and guide levers can move by means of a common drive unit, or they can each have their own drive unit. In addition, the guide levers can be coupled to the blocking elements such that movement of the guide levers also causes movement of the blocking elements. For example, the guide levers can be arranged in a guide channel on the inner side of the blocking elements, and drive the blocking elements outward and thereby unfold them when the display is unwound, and pull the blocking elements inward and thereby retract them when the display is rolled in.

[0021] According to another preferred extension, the device has a guiding system with lateral support guiding elements capable of coupling to the roof on opposite sides about the longitudinal axis. The lateral support is configured to move relative to the roof along the longitudinal axis in a predetermined manner, cooperating with the lateral support guiding elements. The lateral support and guiding system can be configured such that the lateral support and the display disposed thereon can be moved from the rearmost part of the roof to the foremost part. Thus, a display for the rear seats of a motor vehicle can be provided, or the display can be moved forward again by means of the lateral support, so that front vehicle passengers can also view the display and the entertainment output by it. Such a forward arrangement is also suitable, for example, for autonomous vehicles in which vehicle passengers do not need to drive the vehicle themselves but can focus on the entertainment output by the display.

[0022] The lateral support and the display disposed thereon can be configured such that they are movable along a predetermined section of the roof, for example, in the front or rear region. Preferably, the lateral support is fully movable, allowing it to move along as large an area as possible under the roof. Partial or full mobility of the lateral support under the roof can particularly contribute to improving the comfort of the vehicle. This is especially noticeable when combined with a cover system featuring a transparent panoramic roof. For example, the display can be rolled up in or on the lateral support when not needed and moved with it to the rear region of the vehicle, thus releasing a particularly large visibility through the roof when the crossbar is not in the center. Alternatively, the lateral support can be configured to be immovable and fixedly coupled to the roof. Thus, the display in or on the roof can have a fixed position or can be configured to be movable with the lateral support.

[0023] In addition, the device has another display coupled to the transverse support in a manner spaced apart from the rollable display, about the longitudinal extension direction of the transverse support. This other display can be constructed as a rigid display. However, preferably, this other display can also be constructed as another rollable display so that it can be stored in a particularly space-saving manner while allowing particularly large visibility through a transparent cover or a transparent roof. Compared to a rigid display (which, for example, flips upward when not in use and is then typically stored horizontally), a particularly large visibility gain in the direction of the vehicle's longitudinal axis can be achieved by means of a rollable display. This can be, in particular, half the screen height, so that a visibility gain of 100mm-150mm can be achieved, for example, in a rigid display that is 300mm high.

[0024] Compared to traditional rigid screens, rollable displays can expand headroom in different locations. Furthermore, trim or sliding roofs (Schiebehimmel) on the underside or inside of the roof can be designed to be smaller. Additionally, visibility is improved in the case of a transparent roof. Moreover, rollable displays, especially in their rolled-up, stowed-away state, allow for a clean design of the screen assembly without a visible display, all within a relatively small structural space.

[0025] Here, the shielding unit is preferably constructed to match the housing of the lateral support member, such that, for example, the material, surface structure, edge orientation, and / or bulge of the housing of the lateral support member are constructed to match the material, surface structure, edge orientation, and / or bulge of the shielding unit. In particular, the fourth shielding element at the lower end is adapted to the housing of the lateral support member in a predetermined manner. The fourth shielding element can be constructed in such a way that, when the display is retracted, the fourth shielding element closes the housing of the lateral support member from below, and all other components of the screen assembly, except for the lateral support member and the lower shielding element, are concealed within the housing of the lateral support member.

[0026] The roof for a motor vehicle according to the invention includes a roof element configured to be coupled to the roof body of the motor vehicle. The roof according to the invention also includes, according to one of the aforementioned embodiments, a device for operating a screen assembly, coupled to the roof element on the side facing the vehicle's interior space. Here, the device can be directly or indirectly connected to the roof element by means of a lateral support member. The lateral support member can be coupled to the roof as a fixed beam or preferably configured to be movable relative to the roof. Therefore, the lateral support member and the display mounted thereon or integrated therein can move along the longitudinal axis below the roof in a predetermined manner and, for example, move to the foremost or rearmost part of the motor vehicle.

[0027] The roof element can be implemented, for example, as a cover system with a glass cover or as a panoramic glass roof. Alternatively, the roof element can also constitute an opaque roof veneer. The roof element can be configured to be raised or extended, and / or fixed in position to the roof body and / or movable relative to it.

[0028] Since the vehicle roof includes an embodiment of the device, the features and characteristics of the device described are also disclosed to the vehicle roof, and vice versa.

[0029] This device, along with the corresponding roof, helps improve the comfort of the vehicle. In particular, it enables the creation of an aesthetically pleasing, side-mounted exterior for a rollable display, which can be compactly stored as a panel-like, fold-down cover. Therefore, the display can be visually appealing from all sides when extended. Thus, in the extended state, the display can be surrounded laterally by a fold-down cover element, from the rear by a fifth cover element (e.g., in the form of a shielding roller blind), and from below by a cover element that closes the lower portion. Additionally, the cover unit can function as a guide mechanism and ensure the stable and reliable unfolding of the rollable display. Attached Figure Description

[0041] Elements with the same construction or function are labeled with the same reference numerals across the figures. For clarity, not all elements shown in the figures are labeled with reference numerals.

[0042] Figure 1The roof 2 of a motor vehicle 1 is schematically shown in a perspective view. The roof includes a roof element, a cover system, or a cover 4 that closes an opening in the roof 2. The cover 4 is, for example, a fixed glass element that is immovable relative to the roof 2. Alternatively, the cover 4 is movable relative to the roof 2 to selectively open and close the opening in the roof 2. The roof 2 may also lack the cover 4 and achieve a slotless roof covering, such as a foldable or flip-up convertible roof that can be stored in the rear region of the motor vehicle 1. Furthermore, the roof 2 may also be constructed as a convertible roof with the cover 4, wherein the cover 4 is configured to fold or flip.

[0043] A transverse support member 13 is arranged below the roof 2, and the transverse support member is configured to move about the longitudinal axis L. The transverse support member 13 realizes a beam or crossbar that can be supported, and the crossbar is indirectly or directly coupled to the roof 2 and / or the cover 4.

[0044] In conjunction with this specification, terms such as “upper,” “lower,” “front,” “rear,” “upper side,” “lower side,” and “horizontal” and “vertical” indicate the orientation or direction of the motor vehicle 1 with roof 2, as it is ready for operation. Figure 1 As illustrated in the diagram, the horizontal plane is thus defined by the drawn xy-plane and oriented perpendicular to the drawn z-direction, which represents the vertical line. The longitudinal axis L corresponds to the vehicle's longitudinal axis, and the drawn arrow indicates the usual forward direction of travel. The rear of the vehicle is arranged or constructed at the rear. Therefore, the lateral support 13 is arranged below the roof 2 and / or integrated into the roof, facing the interior space of the vehicle 1.

[0045] For example, refer to the following Figures 2 to 68 The various devices 10, 20, 30, 40, 50, 60, and 70, as will be explained, enable convenient operation, orientation, and decoration of the screen assembly coupled to and arranged on and / or integrated within the lateral support 13. Devices 10 and / or 20 and / or 30 and / or 40 and / or 50 and / or 60 are particularly advantageous in working together, but can also be arranged individually to provide corresponding functionality.

[0046] With the aid of devices 10-70, a screen assembly with at least one display 11, 12 can be made for the roof 2, which can be constructed in a particularly space-saving manner and can help improve the comfort of the vehicle 1.

[0047] Figures 2-12 Embodiments of the device 10 for operating a screen assembly for the roof 2 are shown in different views. Figures 13-16 Further views and / or components of device 10 and / or devices 20, 40 and / or 70 are shown.

[0048] according to Figure 2 The cover 4 is preferably configured as a transparent roof element, which allows visibility through the roof 2. The cover 4 may be configured as transparent glass and form a panoramic roof, which is fixedly connected to the roof body 3 of the vehicle 1. Figure 2 In this case, the device 10 is arranged in the rear or tail area of ​​the roof 2, or it is moved backward and stored away.

[0049] Device 10 includes a rollable display 11, which can be wound and unwound via a display shaft 14, and is coupled to a lateral support 13. The display shaft 14 is coupled to the lateral support 13 via a shaft attachment 16 (see [link to device 10]). Figure 10-13 The transverse support member 13 is coupled to the roof 2 such that it extends primarily transversely to the longitudinal axis L. Therefore, the main extension direction or longitudinal extension direction of the transverse support member 13 extends substantially from one side of the roof 2 to the opposite side of the roof 2.

[0050] The rollable display 11 is particularly implemented as an OLED display and is also referred to as the first display 11 as necessary in the following description. The rollable display 11 can be constructed as a flexible screen that is wholly or partially rollable or bendable. In addition to the first display 11, the device 10 also has another display 12, which is coupled to the lateral support 13 in a manner spaced apart from the first display 11 about the longitudinal extension direction of the lateral support 13. The other display 12 is configured as a rigid display and is also referred to as the second display 12 as necessary in the following description.

[0051] It is noted in association that, instead of a rollable display and a rigid display 11, 12, the device 10 according to a preferred embodiment includes two rollable displays coupled side-by-side to or integrated into a transverse support 13. However, for the sake of simplicity, the advantages of a configuration in which a rollable first display 11 is combined with a rigid second display 12 are described and illustrated.

[0052] Figure 3 The diagram shows a vehicle roof 2 without a transparent cover 4, in which a lateral support 13 is fully rearward, and the first and second displays 11, 12 are retracted or folded up. Since the first display 11 represents a rollable display, the illustrated non-operating or parking position corresponds to a rolled-up state in which the rollable display is arranged at least substantially around the display axis 14. This rolled-up state can also be referred to as the non-operating state of the first display 11. Furthermore, this rolled-up state can also be referred to as a state in which the first display 11 is folded up, retracted, clamped, wound up, or retracted.

[0053] Because the second display 12 is a rigid display, the non-operating position or parking position illustrated corresponds to the folded-down (flipped-back) state, in which the rigid display is flipped upwards and extends substantially along the roof 2 or cover 4. This folded-down state can also be referred to as the non-operating state of the second display 12. Furthermore, the folded-down state can also be referred to as the state in which the second display 12 is folded up, retracted, flipped upwards, or retracted.

[0054] exist Figure 4 The diagram illustrates the intermediate position achieved by moving the transverse support 13 forward until it reaches the desired position below the roof 2, or cover 4. Furthermore, the two displays 11 and 12 are shown in their respective deployed states, in which they are ready to output entertainment programs.

[0055] The unfolded state of the first display 11 can also be referred to as the operating state. Furthermore, this unfolded state can also be referred to as the state in which the first display 11 is extended, spread open, rolled up, or unwound. Similarly, the unfolded state of the second display 12 can also be referred to as the operating state. Furthermore, this unfolded state can also be referred to as the state in which the swingable second display 12 is flipped (flipped open), flipped downwards, or extended.

[0056] Displays 11 and 12 are oriented such that, in the extended state of readiness for operation, their respective luminous front faces are oriented towards the rear of the vehicle. Regarding the drawn longitudinal axis L, device 10 has a retractable display 11 on the left side of the transverse support 13 and a rigid display 12 on the right side. Alternative arrangements are possible.

[0057] exist Figure 5 Another perspective view of device 10 is shown, in which the lateral support 13 is moved fully forward (forward) about the longitudinal axis L and the indicated direction of travel. Furthermore, the two displays 11 and 12 are ready to output in their respective operating states. This forward position of the lateral support 13 is useful, for example, if the vehicle 1 is constructed as an autonomous vehicle and capable of automatic driving. Furthermore, if the vehicle 1 is parked, for example, for a driving rest, such entertainment positions of the displays 11 and 12 can also be pre-set.

[0058] The mobility of the lateral support member 13 is provided by means of the guide system 60, and in particular, reference is made to the following regarding... Figures 64-68 The description.

[0059] exist Figure 6 The image shows displays 11 and 12 extending from a movable lateral support 13, viewed from a rear-facing angle. Figure 7 The respective views of the protruding displays 11 and 12 are shown from above, wherein the lateral support 13 obstructs the view of the displays 11 and 12.

[0060] exist Figure 8 The retracted displays 11 and 12 on the movable transverse support 13 are shown in a rearward view. Figure 9 The corresponding views of the retracted displays 11 and 12 are shown from above. Specifically based on... Figure 9 The advantages of the rollable display 11 are evident, as it can be stored in a particularly space-saving manner and does not protrude from the transverse support 13 in the x-direction or along the longitudinal axis L. Therefore, a particularly large gain in visibility through the cover 4 can be achieved, for example, corresponding to half the length or height of a rigid display 12. Thus, the rollable display 11 facilitates a screen assembly that, compared to a deployable rigid display, achieves improved visibility and provides installation space advantages.

[0061] Figure 10 and 11 An embodiment of the display shaft 14 is shown, on which a rollable display 11 is wound or unwound. The display shaft 14 is cylindrical and rotationally symmetrical. The display shaft 14 is constructed as a hollow shaft and surrounds a central axis 15. Shaft attachments 16 are arranged on opposite sides of the display shaft 14 and coupled to the central axis 15.

[0062] A plurality of tensioning elements in the form of drive springs 17 are arranged between the display shaft 14 and the spindle 15. Three drive springs 17 are arranged at each of the two opposite free ends with respect to the longitudinal extension direction of the display shaft 14. The drive springs 17 are correspondingly coupled to the display shaft 14 on one side and to the spindle 15 on the other, and are configured to tension the display 11 in a predetermined manner when unwound from and wound onto the display shaft 14. The drive springs 17 form a preferred variant of the built-in spring element, which facilitates: the rollable display 11 can be operated and stored in a small installation space, and provides a useful force to tension the rollable display 11.

[0063] The rollable display 11 and display shaft 14 are constructed in a particularly compatible manner such that they together have a diameter in the range of 40 mm to 100 mm with respect to the rolled state and with respect to the radial direction with respect to the longitudinal extension direction transverse to the display shaft 14.

[0064] Figure 12A partial sectional view from the side shows a device 10 having a transverse support 13 and a display shaft 14. The transverse support 13 has a housing 131 in which the display shaft 14 is arranged. Thus, the rollable display 11 can be arranged in a concealed manner within the housing 131 while wound around the display shaft 14. Figure 12 The display 11 is shown in its extended state and can be rolled up. Figure 13 The image shows the retracted state of the rollable display 11.

[0065] exist Figures 12-16 The diagram also illustrates other kinematic components, such as those controlling the extension movement of the retractable display 11. The device 20 that enables this is also called the guide mechanism 20 and is integrated at the rear. Figures 17-27 To describe. Furthermore, in Figures 12-16 The illustration also depicts device 40 and its components. Device 40 is also referred to as fixed unit 40, and in particular, reference is made to... Figures 43-45 And related descriptions. Furthermore, components of device 70, also known as a shielding unit 70, are shown, providing the display 11 with a retractable and expandable exterior part (Verkleidung). Later, especially in conjunction with... Figures 69-75 Description of occlusion unit 70.

[0066] The device 10 also includes a shielding element 19 (e.g., in the form of a roller blind) that can be wound and unwound by means of a shielding shaft 18. The shielding shaft 18 is coupled to the transverse support 13 and arranged in the housing 131 as the display shaft 14. The shielding element 19 is associated with the back side 112 of the rollable display 11 such that the shielding element 19 covers the back side 112 in a predetermined manner when the first display 11 is wound and unwound.

[0067] The shielding element 19 is coupled to the shielding shaft 18 at its upper end and to the fixing unit 40 at its lower end. This also applies to the rollable display 11, which is coupled to the display shaft 14 at its upper end and to the fixing unit 40 at its lower end (see [link to relevant documentation]). Figure 16 When unwinding the shielding element 19 and the rollable display 11, the fixing unit 40 moves away from the transverse support member 13 by means of the guide mechanism 20, and moves towards the transverse support member 13 when winding the shielding element 19 and the display 11. The shielding shaft 18 and the display shaft 14 are constructed to match each other so that the shielding element 19 and the display 11 can be wound and unwound synchronously.

[0068] and Figure 12 and 13 similar, Figure 14 and 15The diagram shows the extended and retracted states of the rollable first display 11, focusing on the kinematic components of the guide mechanism 20, while the first display 11 and shielding element 19 are not shown. The guide mechanism 20 enables reliable unwinding and stable unfolding, as well as winding and clamping of the rollable display 11 and shielding element 19. For this purpose, the guide mechanism 20 has multiple guide levers 21, 22, and 23, which are electrically movable by means of a drive unit 24. The drive unit 24 is particularly configured as a central drive with an electric motor.

[0069] according to Figure 12 Some of the guide levers 22, 23 are also configured as lateral blocking elements 72, 73 or coupled thereto, to form a satisfactory lateral closure or visual protection for the roll-up display 11. In particular, the form shown for such baffle elements can contribute to convenient visual protection and reliable operation of the guide mechanism 20. The shielding element 19 forms a rollable visual protection element that, in its extended state, conceals the wiring and / or electronic drive components of the rollable display 11. The guide levers 22 and 23 are correspondingly formed as laterally retractable baffles on opposite sides of the rollable display 11 as lateral visual protection elements. The tensioned state of the unwound display 11—as it is in Figure 12 As illustrated in the diagram—specifically established by the drive spring 17 in the display shaft 14. Correspondingly, the tension state of the unwound shielding element 19—as it is in Figure 12 As illustrated in the diagram, this can be established via the spring element in the visual protection axis, or shielding axis 18.

[0070] Figures 17-27 Embodiments of a vehicle roof 2 having device 10 and a guide mechanism 20 for the controlled unfolding and retraction of a rollable display 11 are shown in different views. Figures 17-21 The perspective view shows the different positions and states of the device 10 and the guide mechanism 20 used to operate the screen components. Figures 22-27 An embodiment of the guide mechanism 20 is shown in detail.

[0071] For clarity, as long as it is visible, in Figures 17-27 Only the rollable display 11 is illustrated in the diagram. Therefore, the guide mechanism 20 is described in conjunction with the rollable display 11. However, another, second display 12 is preferably arranged side by side with the rollable first display 11 on the transverse support 13 as another rollable display.

[0072] Figure 17 The device 10 is shown in its parked position, wherein the device is retracted in the rear area of ​​the vehicle and the display 11 is retracted.

[0073] Figure 18 The device 10 is shown in a first intermediate position, wherein the display 11 is still retracted or rolled up.

[0074] Figure 19 Showing according to Figure 18 The device 10 is in a first intermediate position, wherein the display 11 is extended or spread out.

[0075] Figure 20 The device 10 is shown in another position, in which the lateral support 13 is moved fully forward and the display 11 is retracted or rolled up.

[0076] Figure 21 Showing according to Figure 20 The device 10 is located at the very front, in which the display 11 is extended or spread out.

[0077] The guide mechanism 20 is used to extend or unroll and retract or clamp, and the guide mechanism can be used to achieve this. Figures 22-27 To configure. Figure 22 and Figure 23 The study examines the guiding mechanism 20, which includes a rotating gate (Drehkreuz) 25. In Figures 24-27 An alternative embodiment of the guide mechanism 20 is shown, in which the guide mechanism 20 has a lever actuator 26.

[0078] The guide mechanism 20 is coupled to the transverse support member 13 and includes a plurality of guide levers 21, 22, and 23, which are coupled to the rollable display 11 and configured to open the display 11 when unwound from the display shaft 14 and 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 arranged relative to the right and left sides of the display 11, respectively. Therefore, one side of the guide mechanism 20 is described primarily below, while characteristics can be adapted accordingly to the other side. Differences will be indicated by reference to the right and left sides of the guide mechanism 20 or the rollable display 11 if necessary.

[0079] The first guide lever 21 can be oscillatingly coupled to the rotating gate 25 or the lever actuator 26 on one hand, and oscillatingly coupled to the second guide lever 22 on the other hand, which can also be intentionally configured as a baffle element (see...). Figure 12 On the right side, the coupling position of the first guide lever 21 with the rotating gate 25 or the lever actuator 26 constitutes the first swing axis S1. On the left side, the coupling position of the first guide lever 21 with the rotating gate 25 or the lever actuator 26 constitutes the second swing axis S2.

[0080] The second guide lever 22 is oscillatingly coupled to the transverse support member 13 on one hand, and oscillatingly coupled to the third guide lever 23 on the other hand. The coupling between the second guide lever 22 and the transverse support member 13 can be provided indirectly or directly. The third guide lever 23 is oscillatingly coupled to the second guide lever 22 on one hand, and oscillatingly coupled to the fixed unit 40 on the other hand.

[0081] The guide mechanism 20 and guide levers 21, 22, and 23 can be driven by the drive unit 24 and can be electrically unfolded and retracted. The electric drive unit 24 is arranged on the transverse support member 13 and is integrated, for example, in the housing 131 and coupled to the rotating grid 25 or the lever actuator 26. The drive unit 24 can initiate the rotation of the rotating grid 25 or the lever actuator 26, thereby initiating the swinging of the guide levers 21, 22, and 23 and the winding or unwinding of the rollable display 11.

[0082] The first and second guide levers 21 and 22 are configured as elongated, bent guide rods, while the third guide lever 23 is configured as a straight rod. This preferred configuration facilitates the particularly space-saving folding and unfolding of the guide mechanism 20 and the storage of the rollable display 11. The guide levers 21, 22, and 23 can be configured in particular as stable and narrow metal components to enable reliable unwinding and unfolding of the display 11 and, moreover, to be folded and stored in a space-saving manner. Alternatively, one or more of the guide levers 21, 22, and 23 can be configured as plastic components.

[0083] The guiding mechanism 20 is constructed with a scissor mechanism, by means of which the swing axes S1 and S2 and the guiding levers 21, 22, and 23 are guided in a controlled manner. Using the scissor mechanism with the rotating gate 25, according to... Figure 22 and 23 The swing axes S1 and S2 can be guided up and down. Figure 22 The diagram shows the retracted or folded state of the scissor mechanism, in which the display 11 is rolled up and the guide levers 21, 22, and 23 are housed in a bent position. In this state, the second swing axis S2 is arranged vertically above the first swing axis S1. A rotation axis R3, consisting of a rotating gate 25, is constructed or arranged between the two swing axes S1 and S2. Figure 23 Shown according to Figure 22 The guide mechanism 20 of the scissor mechanism is in an extended or retracted state, in which the display 11 is opened and the guide levers 21, 22, and 23 are oriented in a straightened position. Therefore, in the retracted state and in the extended state, a corresponding swing axis of the swing axes S1 and S2 is arranged above the other swing axis and the rotation axis R3 of the rotating gate 25.

[0084] Compared to the embodiment with a rotating gate 25, the embodiment with a lever actuator 26, which has a scissor mechanism configuration, is different. Figures 24-27 The guide mechanism 20 enables a more space-saving arrangement of the display 11 within or on the transverse support 13. The lever actuator 26 includes two gear elements 27 and 28, coupled to the drive unit 24 on one side and to the first guide lever 21 on the other. The first gear element 27 is rotatable about a first axis of rotation R1, and the second gear element 28 is rotatable about a second axis of rotation R2. The gear elements 27 and 28 mesh with each other through their toothed structure, allowing the drive unit 24 to drive only one gear element to also move the corresponding other side of the guide rods 21, 22, and 23. Alternatively, both gear elements 27 and 28 can be driven by the drive unit 24, and furthermore, an embodiment in which the gear elements 27 and 28 do not contact each other is also feasible. With the aid of the drive unit 24, rotation of the gear elements 27 and 28 of the lever actuator 26 can be initiated, thereby initiating the oscillation of the guide levers 21, 22, and 23, and the winding or unwinding of the coilable display 11.

[0085] Figure 24 The diagram 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 swing axes S1 and S2 are arranged at approximately the same height about the vertical line and above the rotation axes R1 and R2 of the gear elements 27 and 28. Therefore, compared to the embodiment with rotating gate 25, the fixing unit 40 coupled to the display at the lower edge 111 of the rollable display 11 can move closer to the underside of the drive unit 24. The fixing unit 40 can be coupled to the rollable display 11 segmentally or entirely along the lower edge 111. Therefore, the guide mechanism 20 and the rollable display 11 can be housed particularly flat under the roof 2, which can contribute to greater headroom for vehicle passengers.

[0086] Figure 25 Shown according to Figure 24 The guide mechanism 20 of the scissor mechanism is in an extended or retracted state, in which the two swing axes S1 and S2 are arranged approximately at or slightly below the height of the rotation axes R1 and R2.

[0087] Guide levers 21, 22, and 23 are coupled to the drive unit 24 on one side and to the fixing unit 40 on the other, which is coupled to the display along the lower edge 111 of the rollable display 11. Therefore, the fixing unit 40 moves toward the lateral support 13 as the display 11 is rolled up by means of the guide levers 21, 22, and 23. (See previous reference...) Figures 12-16Described, the shielding element 19 can also be unwound from or wound onto its shielding shaft 18 by means of the guide mechanism 20.

[0088] Figure 26 and Figure 27 Based on 3D illustrations Figure 24 In the retracted state and according to Figure 25 The guide mechanism 20 with lever actuator 26 is shown in its extended state. Furthermore, the diagram illustrates components of the guide system 60 that enable the mobility of the lateral support member 13. In this regard, refer to the following... Figures 64-68 The description.

[0089] The guide mechanism 20 provides a space-saving and reliable guide linkage mechanism for the rollable display 11. The guide mechanism 20 is specifically configured to allow for continuous extension and retraction of the rollable display 11, thereby enabling the establishment of desired intermediate positions 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 adjusted to a desired height within the vehicle's interior space. Alternatively, the guide mechanism 20 may also provide multiple predetermined intermediate positions, allowing the display 11 to extend and retract progressively. Alternatively, the guide mechanism 20 may also be configured such that the display 11 can only be fully retracted or extended.

[0090] Figures 28-42 The device 30, also referred to hereinafter as the tilting mechanism 30, is shown in different views. The tilting mechanism 30 enables a dual tilted position for both the rollable first display 11 and the rigid second display 12. Therefore, displays 11 and 12 can be intentionally tilted or angled about a horizontal first plane EA1 and about a vertical second plane EA2 (see [reference]). Figure 33 and 35 ).

[0091] Figure 28 The roof 2 is shown in a top view, with the two displays 11 and 12 retracted into their parking position.

[0092] Figure 29 The middle position of the transverse support 13 with retracted displays 11 and 12 is shown in a perspective view. Figure 30 Shown from top view according to Figure 29 2. The roof of the car.

[0093] Figure 31 The middle position of the transverse support 13 with protruding displays 11 and 12 is shown in a perspective view. Figure 32 Shown from top view according to Figure 31 2. The roof of the car.

[0094] Figure 33 The foremost or frontal position of the transverse support 13 with the protruding displays 11 and 12 is shown in a top view. Figure 34 Shown from top view according to Figure 33 The roof 2 has retractable displays 11 and 12.

[0095] Figure 35 The retracted displays 11 and 12 are shown in a cross-sectional view along the second plane EA2 with a rearward viewing direction. Figure 36 Shown in a three-dimensional view according to Figure 35 2. The roof of the car.

[0096] Figure 37 and Figure 38 Showing according to Figure 35 and Figure 36 The roof 2 has protruding displays 11 and 12, which have a rearward viewing direction.

[0097] Figure 38A and Figure 38B The kinematic components for unfolding and retracting the rigid second display 12 in unfolded and retracted positions, as well as for tilting, are schematically shown.

[0098] Figure 39 and Figure 40 A side sectional view perpendicular to the longitudinal axis L shows the kinematic components for unfolding and retracting, as well as the obliquely rigid second display 12. Figure 39 The second display 12 is flipped upwards or folded down, while Figure 40 The second display 12 can be partially or completely flipped downwards or unfolded. The desired angle of the second display 12 relative to the vertical line can be adjusted by means of the lever mechanism 37.

[0099] Figure 41 and Figure 42 A cross-sectional view along the longitudinal axis L shows the kinematic components of the first display 11 for unfolding and folding, as well as its oblique flexibility. Figure 41 The first display 12 is retracted or rolled up, while Figure 42 The second display 12 extends or opens fully.

[0100] The inclined mechanism 30 includes a plurality of guide elements 31-36 that couple the corresponding display 11 or 12 to the transverse support member 13. Guide elements 31-33 are associated with the second display 12 and may also be referred to as the first, second, and third transverse support member coupling portions 31-33. Guide elements 34-36 are associated with the first display 11, and the guide elements include a chute guide element 34, a chute track 35, and a guide pin 36.

[0101] Guide elements 31-36 are configured such that the respective displays 11, 12 are oriented along first axes A1, A2 in the unfolded state with respect to their associated lower edges 111, 121, and along second axes A3, A4 in the retracted state. The first axes A1, A2 are oriented within a first plane EA1, which is supported by the longitudinal axis L and the longitudinal extension direction of the transverse support member 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 adjusted such that they each form an angle of less than 90° with the longitudinal axis L in the unfolded state (see [reference]). Figure 32 and 33 Here, the smaller angle between axes A1 and A2 and the longitudinal axis L is called the enclosed angle. Therefore, according to Figure 32 Regarding the intersection of axis A1 and longitudinal axis L as illustrated in the diagram, the angle at the upper right (towards the rear of the vehicle) or lower left (towards the front of the vehicle) can be referred to as the enclosed angle. For axis A2, correspondingly, the angle at the upper left (towards the front of the vehicle) or lower right (towards the rear of the vehicle) can be referred to as the enclosed angle.

[0102] The second axes A3 and A4 of displays 11 and 12 are oriented within a second plane EA2, which is perpendicular to the first plane EA1 and represents a vertical 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 be adjusted such that, in the retracted state, they form an angle greater than 0° with the first plane EA1 (see [reference]). Figure 29 , 35 And 36). Similarly, here, the smaller angle between axes A3, A4 and the horizontal plane EA1 is considered the enclosed angle. Therefore, according to... Figure 35 Regarding the intersection of axis A3 and the horizontal plane EA1 (not drawn for clarity), the angle to the lower right (towards the outside of the vehicle) or upper left (towards the center of the vehicle) can be called the enclosed angle. For axis A4, correspondingly, the angle to the lower left (towards the outside of the vehicle) or upper right (towards the center of the vehicle) can be called the enclosed angle.

[0103] Therefore, displays 11 and 12 can be respectively set to a predetermined tilt position along their first axes A1 and A2 in the unfolded state, and a predetermined tilt position along their second axes A3 and A4 in the retracted state.

[0104] The first axes A1 and A2 take into account the viewing direction or line of sight of a vehicle passenger who is not typically seated centered in front of the corresponding displays 11, 12 in the vehicle 1, but rather slightly offset from the center of the displays. Therefore, displays 11 and 12 can be tilted outwards toward the corresponding outer side of the vehicle in a predetermined manner with respect to their luminous front sides, such that the line of sight substantially corresponds to the normal direction of the front side of the associated displays 11, 12 (see...). Figure 32 ).

[0105] With the ability to be arranged along the second axes A3 and A4, displays 11 and 12 can be housed higher in the middle of the vehicle than in the outer areas. Therefore, displays 11 and 12 can be housed in a parking position by means of an inclined mechanism 30, such that they extend primarily along the roof 2, or cover 4. The roof 2 and cover 4 are not typically constructed flat in a horizontal plane, but are pre-arched and, in relation to their placement on the motor vehicle 1, are higher at their center than at their side edges. With the described inclined mechanism 30, the arching of the roof 2 and cover 4 can be taken into account and contributes to increased headroom for vehicle passengers (see [link to description]). Figure 35 and 36 ).

[0106] The tilting mechanism 30 of the first display 11 and the tilting mechanism 30 of the second display 12 are respectively configured such that the corresponding second axes A3, A4 are pre-defined on the lower side of the roof 2 in match with the positions of the roof 2 and / or cover 4 and the displays 11, 12, so that the associated displays 11, 12 extend along the longitudinal extension direction of the transverse support 13 in the retracted state in accordance with the shape of the roof 2 and / or cover 4 and are retracted substantially parallel to the roof 2 and / or cover 4.

[0107] The tilting mechanism 30 of the first display 11 includes a slide guide element 34 coupled to the transverse support member 13 and having a slide track 35. A guide pin 36 is engaged in the slide track and can be guided in a predetermined manner within the slide track. The guide pin 36 is constructed on or coupled to the second guide lever 22 of the guiding mechanism 20, and thus, together with the first guide lever 21, predetermines the guided movement of the second guide lever 22 when unfolding and retracting the rollable display 11 (see [link]). Figure 41 and 42 ).

[0108] The tilting mechanism 30 of the second display 12 includes a lever mechanism 37 coupled to the transverse support member 13, which enables the second display 12 to be unfolded and folded. The lever mechanism 37 includes three transverse support member coupling portions 31, 32, and 33 of different sizes, configured to swing, such that the second display 12, in a retracted state, has its lower edge 121 oriented along the output axis A0 (see...). Figure 34 The output axis A0 is oriented perpendicular to the longitudinal axis L within the first plane EA1. Therefore, the second display 12 is oriented horizontally without tilting in the designated parking position below the roof 2. Thus, the edge of the second display 12 is substantially parallel or perpendicular to the longitudinal axis L in the folded-down state. Regarding the horizontal first plane EA1, the second display 12 is tilted along the second axis A4 (see...). Figures 35-36 ).

[0109] The first transverse support coupling portion 31 allows the second display 12 to be oscillatingly coupled to the transverse support portion 13 and has an oscillation axis S6. The oscillation axis S6 also corresponds to the oscillation axis of the third transverse support coupling portion 33. Regarding... Figure 38A As illustrated in the diagram, the first lateral support coupling portion 31 is arranged in the left region of the rigid display 12, while the third lateral support coupling portion 33 is arranged in the right region of the rigid display 12. Therefore, the second lateral support coupling portion 32 is centrally arranged and has three swing axes S7, S8, and S9. The second lateral support coupling portion 32 includes a sliding lever 321 and another lever 322. The sliding lever 321 is swingably coupled to the lateral support 13 on one hand and to the lever 322 on the other. Furthermore, the lever 322 is swingably coupled to the display 12 (see [reference]). Figure 40 The slide lever 321 includes a slide, and a guide pin, such as the guide pin of the drive unit 24, is inserted into the slide. The guide pin drives the slide lever 321 to swing and causes the display 12 to flip or unfold.

[0110] The aforementioned tilted position of the second display 12 can be reliably and stably set by means of the described transverse support couplings 31, 32, 33 and the swing axes S6-S9 associated therewith. Regarding the horizontal axis, the swing axes S6-S9 extend obliquely in a predetermined manner to construct the described tilted position of the second display 12.

[0111] The tilting mechanisms 30 and 37 enable the second display 12 to transition to an unfolded state, in which the second display 12 is oriented with a predetermined tilt along the first axis A2 (see [reference]). Figures 35-40Furthermore, the first and second displays 11 and 12 can be unfolded by means of their tilting mechanism 30 such that their lower edges 111, 121 are oriented substantially horizontally (see [reference]). Figures 37-38 ).

[0112] Figures 43-45 A side sectional view of device 40, also referred to as fixing unit 40, is shown. Fixing unit 40 is coupled to a rollable first display 11 at its lower edge 111 and includes a fixing beam 42 extending along the lower edge 111 of the display 11 and configured to move away from the lateral support 13 when unwinding the display 11 by means of a guide mechanism 20 and toward the lateral support 13 when winding the display 11. Fixing unit 40 works in conjunction with display axis 14 to tension the rollable display 11, and preferably also works in conjunction with shielding axis 18 to tension the shielding element 19.

[0113] The fixing unit 40 has a carrier layer 41 coupled to the front side 113 of the rollable display 11. The carrier layer 41 is particularly configured as a film element, such as a PET film, and is especially used to protect the display 11 and to stably and reliably attach it 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 fixing beam 42 on its underside 421 by force-locking, form-locking, and / or material-locking.

[0114] The fixing beam 42 has a rounded profile in the respective reversing regions to enable reliable and gentle tensioning of the respective elements, in which the shielding element 19 and the carrier layer 41 are reversed. The fixing beam 42 is made, for example, of aluminum or glass fiber reinforced plastic and has sufficient rigidity to reliably attach and support the display 11.

[0115] As with shielding element 19, carrier layer 41 has a plurality of fixed openings 48, and a plurality of fixed elements 43 extend into or through these fixed openings, the fixed elements being constructed or arranged on the underside 421 of fixed beam 42.

[0116] Preferably, the fixing element 43 and the fixing opening 48 are constructed to match each other in shape and number. For example, the fixing beam 42 is integrally constructed as a plastic molded part with the fixing element 43, which is in the form of a longitudinally elongated button. The fixing element forms a corresponding hanging tongue and is equidistantly arranged on the lower side 421 (see...). Figure 44 ). Figure 44 The diagram schematically shows a view of the fixing beam 42 from below. The fixing opening 48 is constructed in the form of a slot, into which the fixing element 43 is introduced.

[0117] The shielding element 19 and the carrier layer 21 each have a fixing opening 48, which is configured in a predetermined manner in terms of its position such that a corresponding fixing element 43 of the fixing beam 42 extends through the associated fixing opening 48 of the shielding element 19 and the associated fixing opening 48 of the carrier layer 21. Therefore, force-locking and / or form-locking connections can be provided between the shielding element 19 and the carrier layer 41 and the fixing beam 42; alternatively or additionally, the shielding element 19 and / or the carrier layer 41 can be bonded to the fixing beam 42.

[0118] according to Figure 45 The carrier layer 41 and / or shielding element 19 have strip-shaped reinforcing elements 49, such as perforated metal strips, in their respective edge regions where they are coupled to the fixed beam 42. Therefore, the respective edge regions can be reinforced to establish a particularly reliable and stable coupling between the carrier layer 41 and / or shielding element 19 and the fixed beam 42.

[0119] The fixing unit 40 also includes display electronics 44, which is mechanically coupled to the fixing beam 42 on its upper side 422. Display electronics 44 is also signal-technically coupled to the rollable display 11 via coupling interface 46 and flexible circuit unit 47, providing the display 11 with pre-defined electronic functionality, for example, in a manner compatible with the on-board computer of the vehicle 1. The coupling stress between the circuit unit 47 and the display electronics 44 is preferably set to be less than the coupling stress between the carrier layer 41 and the fixing beam 42. The circuit unit 47 is, for example, configured as a flexible printed circuit electronics device.

[0120] The shielding element 19 is constructed, for example, as a textile element in the form of a roller blind or as an opaque layer, to shield the electronic and / or mechanical components on the back side 112 of the rollable display 11. Furthermore, the fixing unit 40 has a shielding portion 45 that is coupled at its lower side 421 to the fixing beam 42, the shielding element 19, and the carrier layer 41 to aesthetically conceal the coupling locations of these elements. Additionally, the shielding portion 45 has a rounded profile outwards, or in the direction toward the vehicle interior space, to contribute to headroom for the safety of vehicle passengers.

[0121] Figures 46-63 The device 50, also referred to hereinafter as cable storage unit 50, is shown in different views. The cable storage unit 50 enables a reliable supply of data and current to a flexible first display 11 and a rigid second display 12.

[0122] Figure 46 and Figure 47The arrangement of the cable storage unit 50 in the rear region of the roof 2 is shown in perspective view. Alternatively, the cable storage unit 50 may be integrated in the front region of the roof 2.

[0123] Figures 48-60 The cable storage unit 50 is shown in different views.

[0124] Figures 61-63 The illustrations depict schematic embodiments of possible tensioning schemes to keep the supply cables 51, 52 of the cable storage unit 50 taut.

[0125] The cable storage unit 50 has a first supply cable 51 and a second supply cable 52, which respectively provide data and / or current supply to displays 11 and 12. Thus, the first supply cable 51 may be technically associated with the first display 11, and the second supply cable 52 may be technically associated with the second display 12. This may include data supply devices and / or current supply devices. Alternatively and preferably, the data supply devices and current supply devices are positioned separately from each other, such that, for example, the first supply cable 51 provides corresponding current supply to both displays 11 and 12, and the second supply cable 52 provides corresponding data supply to both displays 11 and 12. Separate supply is particularly advantageous for voltage reasons and in view of electromagnetic compatibility and / or safety. Supply cables 51 and 52 are respectively constructed as sheathed energy chains having a coupling structure 58, which works in conjunction with the cable guide 57 to achieve stable, reliable, and low-noise guidance of the supply cables 51 and 52. If such an energy chain sheath is not useful, then unsheathed sections 56 and 59 of supply cables 51 and 52 are also provided.

[0126] Cable guides 57 are arranged on opposite sides of the roof 2 and enable controlled guidance of supply cables 51 and 52 from the rear to the front within the roof 2. To allow for such relatively large mobility of the transverse support 13, the supply cables 51 and 52 are arranged vertically relative to each other within the housing 54 (see [reference]). Figures 50-53 The housing 54 is configured to store and release supply cables 51, 52 and is integrated into the rear crossbar of the roof 2. Alternatively, it can be integrated into the front crossbar or a baffle of the roof 2. To ensure that the supply cables 51, 52 can be reliably guided vertically to each other, for example, a partition wall is provided in the housing 54 between the supply cables 51, 52, the partition wall being constructed for the bottom of the upper supply cable 52. A cover for the lower supply cable 51 is provided by the bottom of the housing.

[0127] Supply cables 51 and 52 are secured in position at their ends away from the respective displays 11 and 12, for example by means of (not shown) retaining hooks. From the secured ends, supply cables 51 and 52 extend through housing 54 and exit housing 54 on their associated side via corresponding reversing sections 55. The reversing sections 55 are constructed together with or coupled to housing 54 and are configured to commutate supply cables 51 and 52 and oriented along the longitudinal axis L, leading them into cable guides 57. The reversing sections 55 can be integrally constructed with housing 54, and possibly partition walls and covers, by means of injection molding. Through the cable guides 57, supply cables 51 and 52 reach the associated displays 11 and 12. Furthermore, the unsheathed sections 56 of supply cables 51 and 52 are illustrated separately (see Figure 56). Figure 53 ).

[0128] Therefore, the supply cables 51 and 52 extend in sections along the longitudinal axis L on the corresponding sides of the roof 2 within the cable guide 57 and in sections within the housing 54, wherein the supply cables 51 and 52 in the housing extend in opposite directions up and down relative to each other in the inclined planes E1 and E2 and each has a U-shaped direction switching portion so as to provide a sufficiently long supply line. Figure 52 The illustration shows the possible movement of the U-shaped direction switching sections of the two supply cables 51, 52 when the lateral support member 13 moves closer to or further away from the cable storage unit 50.

[0129] Figure 56 The illustration depicts housing 54, which includes a first tilted plane E1 and a second tilted plane E2. A horizontal plane EA1 is also drawn to illustrate the intentionally predetermined tilted orientation. The first plane E1 is positioned below the second plane E2 about a vertical line, with a first supply cable 51 belonging to the first plane E1 and a second supply cable 52 belonging to the second plane E2 of housing 54.

[0130] The inclined storage of supply cables 51 and 52 within housing 54 provides useful accommodation and also allows for the transfer of the respective supply cables 51 and 52 to a common plane EA1 outside housing 54, so that the supply cables 51 and 52 can be guided at the same height in cable guide 57. Torsion or tension during the transfer of supply cables 51 and 52 from their respective planes E1 and E2 to the horizontal plane EA1 via reversing section 55 can be withstood.

[0131] Supply cables 51 and 52 each have a carriage with a slider 53, which enables low-resistance guiding of supply cables 51 and 52 within the guide channel of the associated cable guide 57 (see...). Figures 58-60Supply cables 51 and 52 for supplying current and data technologies enter the transverse carrier 13 from the cable guide 57 and pass through the transverse carrier to the respective displays 11 and 12 (see...). Figure 54 ).exist Figure 54 The diagram illustrates such a connection, in which supply cables 51 and 52 each have an unsheathed section 59 that extends to the corresponding displays 11 and 12 and can be space-savingly mounted in the transverse support 13, or its housing 131. For clarity, the transverse support 13 and the displays 11 and 12 mounted thereon are... Figure 54 Not shown in the image.

[0132] Preferably, such as Figures 60-63 As shown, the cable storage unit 50 also includes tensioning mechanisms 591, 592, and 593, which are coupled to the corresponding supply cables 51 and 52 and apply a predetermined tension to the supply cables 51 and 52.

[0133] For example, such a tensioning mechanism is implemented in the form of a tensioning linkage that is coupled to an opposing carriage. Alternatively or additionally, such as Figure 61 As shown, tensioning elements 591 and 592 are disposed in the housing 54 in the region of the respective U-shaped direction switching portions of the supply cables 51 and 52. These tensioning elements are configured to be displaceable or stretchable and to apply a tensioning force to the respective supply cables 51 and 52. Such tensioning elements 591 and 592 can be implemented as, for example, tension springs or rope attachments.

[0134] Alternatively or additionally, a tension coupling can be established between the two supply cables 51, 52, as in Figure 62 and Figure 63 As schematically illustrated, two tensioning elements 591 and 592 are coupled to associated supply cables 51 and 52 and another tensioning element 593, which applies force to keep the supply cables 51 and 52 taut in a predetermined manner. The other tensioning element 593 can provide torque or tension acting on the two tensioning elements 591 and 592.

[0135] The described tensioning scheme helps to keep the noise generated during the movement of supply cables 51, 52 low and, in addition, enables controlled and guided extension or retraction of supply cables 51, 52 from or into housing 54. Furthermore, the flexible cover of housing 54 can be constructed to match the geometry of one or more supply cables 51, 52 and to contact or intersect with the supply cables 52 in a predetermined manner to prevent or counteract rattling of supply cables 51, 52 within housing 54.

[0136] With the aid of the cable storage unit 50, a reliable and secure data and current supply to the two displays 11, 12 can be achieved, provided that the lateral support 13 can move along the longitudinal axis L over its entire or as large a usable length as possible under the roof 2. Correspondingly, the supply cables 51, 52 are provided in lengths exceeding, for example, 140 cm. This length of the supply cables 51, 52 is related to the corresponding mobility of the lateral support 13, from which it is advantageous to arrange the supply cables 51, 52 vertically relative to each other in the housing 54 within the front or rear crossbar of the roof 2. If a smaller mobility is provided, such that the supply cables 51, 52 should, for example, only provide a movable length of 50 cm to 100 cm, then storage in the housing 54 can be arranged in a common, especially horizontal, plane. For example, the supply cables 51 and 52 can be constructed to match movable lengths of 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, 110cm, 120cm, 130cm, 140cm, 150cm, 160cm, 170cm, 180cm, 190cm, or 200cm.

[0137] Figures 64-68 The device 60, also known as the guidance system 60, is shown in different views. The guidance system 60 enables reliable and safe guidance of the transverse support 13 and the displays 11, 12 arranged thereon along the longitudinal axis L.

[0138] Figures 64-66 The roof 2 and the transverse support 13 coupled thereto in different moving positions are shown in a perspective view. Figure 64 The illustration shows the lateral support 13 in the parking position, which is housed under the roof 2, for example, in the rearmost area of ​​the vehicle. Figure 65 A beam 13 with displays 11, 12 that flip upwards or retract in the middle position is shown. Figure 66 A beam 13 with upward-flipping or retracting displays 11, 12 is shown in the front position. The beam 13 can be moved continuously by means of a guide system 60, so that any number of intermediate positions can be set as needed between the foremost and rearmost positions.

[0139] Figure 67 and Figure 68The components of the guiding system 60 are shown in a corresponding perspective view. The guiding system 60 has lateral support guide elements in the form of two guide rails 61, which are coupled or are capable of being coupled to the roof 2 on opposite sides about the longitudinal axis L. Lateral support members 13 are coupled to guide slides 64 on opposite sides, which are arranged in corresponding guide channels of the associated guide rails 61.

[0140] The guiding system 60 also includes an electric drive unit 63, particularly in the form of an electric motor, which is coupled to an associated guide slider 64 via a corresponding drive cable 62, allowing the guide slider 64 to be driven by the drive unit 63 and the lateral support member 13 to move electrically along the longitudinal axis L. Alternatively or additionally, manual displacement of the lateral support member 13 may also be provided. Figure 67 As shown, the drive unit 63 can be arranged in the rear region of the roof 2 or alternatively in the front region of the roof 2. In particular, the cable storage unit 50 and the guide system 60 are arranged in the roof 2 in a matching manner.

[0141] The guidance system 60 enables safe and controlled guidance of the lateral support 13. Displays 11 and 12, arranged on the lateral support 13, can move with it and can be adjusted to convenient positions for entertainment output. Furthermore, the extensive mobility of the lateral support 13 releases visibility through the cover 4 without limiting it upwards in the middle of the vehicle by crossbeams, rails, or other obstructions. Therefore, maximum visibility through the roof 2 can be achieved, which is particularly comfortable when combined with the transparent panoramic roof as a roof element.

[0142] Figures 69-75 The device, or rather the shielding unit 70 or its components, are shown in different views. The shielding unit 70 provides a visually pleasing exterior for the rollable first display 11 and covers a predetermined section in order to particularly conceal mechanical and / or electrical attachments and thereby prevent undesirable light from shining onto the back side 112 of the display 11.

[0143] The occlusion unit 70 has a first occlusion element 71, two second occlusion elements 72, two third occlusion elements 73, and a fourth occlusion element 74 (see [link]). Figures 71-75The first shielding element 71 is arranged on or in the middle of the transverse support member 13 and coupled thereto, and serves as an upper attachment member for the other shielding elements 72-74. The fourth shielding element 74 is coupled to the display 11 on the lower edge 111 of the display 11 and forms a lower termination member. The second and third shielding elements 72 and 73 are arranged on opposite sides of the vertical central axis M of the shielding unit 70 from the first shielding element 71 to the fourth shielding element 74 and are correspondingly connected to the first and fourth shielding elements 71 and 74, such that the second and third shielding elements 72 and 73 couple the first shielding element 71 to the fourth shielding element 74.

[0144] The fourth blocking element 74 can achieve according to Figures 13-16 and Figure 43 The fourth shielding element 74 can be coupled to the fixing beam 42, for example, by screw connection, clamping and / or bonding (see [reference]). Figures 69-72 The shielding unit 70, and especially the fourth shielding element 74, is preferably constructed to match the geometry and appearance of the housing 131 of the transverse support member 13. For example, the housing 131 and the fourth shielding element 74 have the same material, the same surface texture, matching edge orientation, and / or the same arching, which can contribute to a unified and particularly attractive appearance.

[0145] In the retracted state of the rollable display 11 (which is accompanied by the folded-down state of the foldable shielding unit 70), the fourth shielding element 74 closes the housing 131 of the transverse support member 13 from below, so that all other components of the shielding unit 70 are concealed within the housing 131 of the transverse support member 13. Therefore, the fourth shielding element 74, which closes the lower part, is preferably adapted to the housing 131 of the transverse support member 13 in a predetermined manner and can be constructed uniformly with the housing or intentionally contrast with it.

[0146] The shielding unit 70 is coupled to the transverse support member 13 and is configured to be rolled up when the display 11 is wound and unwound when the display 11 is unwound, and to form a shielding frame along the lateral edge of the display 11 about the lateral edge of the display 11 (see [link]). Figures 73-75 ).

[0147] The second and third blocking elements 72 and 73, which are paired with each other, are pivotally coupled relative to each other by means of a hinge element 75. Accordingly, a pivot axis S4 is provided at the coupling position between the second and third blocking elements 72 and 73. Furthermore, the second blocking element 72 is pivotally coupled to the first blocking element 71. Accordingly, a pivot axis S3 is provided at the coupling position between the second blocking element 72 and the first blocking element 71. Furthermore, the third blocking element 73 is pivotally coupled to the fourth blocking element 74. Accordingly, a pivot axis S5 is provided at the coupling position between the third blocking element 73 and the fourth blocking element 74.

[0148] In this way, the shielding unit 70 can be configured as a retractable and expandable shielding frame, which provides an aesthetically pleasing exterior around the display 11 and can also be folded up in a space-saving manner and stored in the housing 131 of the transverse support 13. When folded up, the two second and third shielding elements 72, 73 move toward each other at the coupling position of the swing axis S4 (see...). Figure 71 and Figure 72 Here, the swing axis S4 follows both horizontal and vertical movement directions. The swing axis S5 follows essentially vertical movement directions. The swing axis S3 remains essentially fixed in position. If necessary, the swing axes S3 and / or S5 are also constructed in a predetermined manner to allow for certain movements in the vertical and / or horizontal directions, for example, to achieve the storage of the blocking unit 70 in a predetermined tilted position, as combined with... Figures 28-42 The inclined mechanism 30 is described.

[0149] The shielding unit 70 may further include a fifth shielding element in the form of a light-shielding element, which forms a shielding portion for shielding the back side 112 of the display 11. The fifth shielding element is particularly implemented as the aforementioned shielding element 19, which can be wound and unwound by means of a shielding shaft 18 (see...). Figures 60-70 as well as Figures 73-74 Alternatively, the fifth shielding element may form an additional element that faces the back side 112 of the display 11 and covers the back side 112 in a predetermined manner when the display 11 is wound and unwound.

[0150] The shielding elements 71-74 are plate-shaped and formed in a predetermined manner with respect to their lateral extension dimensions across the corresponding thickness, matching the corresponding mounting space. In particular, the second and third shielding elements 72 and 73 are constructed in a predetermined manner with respect to their lateral extension dimensions, matching the gap between the unwound display 11 and the fifth shielding element, or shielding element 19 (see [reference]). Figure 12The shielding elements 71-74 and / or the housing 131 may be made of aluminum or plastic or a mixture of materials. Furthermore, for example, the shielding elements 72-74 may be implemented as components wrapped in material to achieve a desired appearance.

[0151] Preferably, the blocking unit 70 is also constructed in a matching manner with respect to the aforementioned devices 10-60. Therefore, in particular, the second and third blocking elements 72 and 73 can realize the guide levers 22 and 23 of the guide mechanism 20 (see...). Figure 14 and Figures 22-25 Alternatively, the second and third blocking elements 72, 73 and the guide levers 22, 23 can be constructed as separate elements, such that the second and third blocking elements 72, 73 conceal the guide levers 22, 23 in a predetermined manner and provide visual protection for the built-in guide mechanism 20. Furthermore, the deployment of the blocking unit 70 can be automatically controlled by means of the drive unit 24 of the guide mechanism 20. Alternatively or additionally, a separate drive unit can be provided for retracting and unfolding the blocking unit 70.

[0152] Furthermore, preferably, the shielding unit 70 is adapted in shape to one or more functions of the devices 10-60, such as in Figure 75 As illustrated in the diagram, the first shielding element 71 has a first coupling section 76 and an opposing second coupling section 77 for corresponding second shielding elements 72 with different configurations. Accordingly, these second shielding elements 72 have coupling structures for different configurations of the first shielding element 71. The first shielding element 71 also has a protrusion 78. The illustrated configuration of the first shielding element 71 and the second shielding element 72 connected thereto are particularly adapted for reliably unfolding and compactly retracting the shielding unit 70, opening and retracting the display 11 by means of the guide mechanism 20, and / or pre-positioning the extended and / or retracted display 11 at a predetermined angle by means of the tilting mechanism 30.
