[0002] ARRANGEMENT FOR A VEHICLE ROOF AND VEHICLE ROOF

[0003] An arrangement for a vehicle roof is specified, in particular an arrangement for moving a cover for the vehicle roof. A vehicle roof for a motor vehicle is further specified, in particular a vehicle roof that has an arrangement as described herein.

[0004] Arrangements with a movable cover for a vehicle roof can be designed as a so-called externally guided sliding roof, as described, for example, in DE 197 13 347 C2. Alternatively, it is also possible to design the vehicle roof as a so-called spoiler roof, as described, for example, in DE 10 2012 106 545 Al.

[0005] It is desirable to specify a vehicle roof design that enables reliable operation. It is further desirable to specify a vehicle roof design that enables reliable operation.

[0006] The disclosure relates to an arrangement for a vehicle roof. The arrangement includes a frame for coupling to the vehicle roof. In particular, the frame can be inserted into a roof opening of the vehicle roof. The arrangement includes a first cover. The first cover is displaceable along a first direction relative to the frame. In particular, by displacing the first cover, it is possible to selectively open or close the roof opening of the vehicle roof. The arrangement includes a second cover. The arrangement includes a third cover. The second and third covers are each fixedly attached to the frame. Unlike the first cover, the second and third covers are therefore not displaceable relative to the frame to open the roof opening. The first, second, and third covers together close the roof opening in a closed state of the arrangement.In a closed position, the first cover seals off a front part of the roof opening. In an open position of the first cover, the front part of the roof opening is at least partially uncovered.

[0007] The arrangement features a guide rail extending longitudinally along the first direction. The guide rail is fixed to the frame. In particular, the guide rail is not movable relative to the frame. The guide rail is arranged along a second direction between the second and third covers. The first direction can also be referred to as the longitudinal direction. The second direction can also be referred to as the transverse direction. The first and second directions are, in particular, oriented transversely to each other, and especially perpendicularly to each other, and each transversely, and especially perpendicularly to, a third direction, which can also be referred to as the vertical direction.

[0008] The arrangement includes an extension carriage. The extension carriage is guided so as to be slidable along the longitudinal direction in the guide rail. A relative movement of the slider along the guide rail drives a movement of the first cover relative to the guide rail and the frame. The extension carriage and the first cover are coupled to each other by means of a hinge mechanism to move the first cover relative to the frame. The hinge mechanism transmits the longitudinal movement of the drive into a movement of the first cover, in particular into a movement along the vertical direction and a movement along the longitudinal direction. The hinge mechanism has at least seven pivot joints.

[0009] The articulated mechanism incorporates components such as levers and pivot joints to translate the linear movement of the ejector carriage into further movements for the lid. The components of the articulated mechanism are connected to one another via the pivot joints in such a way that the movement of the slider along the guide rail causes components of the articulated mechanism to pivot, in particular the levers. The levers are, for example, each pivotally coupled to one or more of the pivot joints.

[0010] The arrangement with the hinge mechanism forms, in particular, a seven-joint opening mechanism. The hinge mechanism is specifically designed as a seven-joint or more-than-seven-joint mechanism, for example, as a ten-joint or a three-ten-joint mechanism. The opening carriage, to which at least one component of the hinge mechanism is pivotably connected, is supported centrally on the guide rail between the second and third covers. The opening carriage is guided centrally, and thus the first cover is supported centrally. In particular, this eliminates the need for the two conventionally provided guide rails in the area of ​​the second and third covers. Conventionally, two guide rails are arranged laterally at the edge of the roof opening, in which the cover is also supported at the

[0011] The rear edge is laterally supported by means of two mechanisms.

[0012] The hinge mechanism allows the first cover to slide above the second and third covers. This arrangement is specifically designed as an externally guided sliding roof. The support on the guide rail, located between the second and third covers, enables a large sliding range for the first cover, thus allowing for a wide-opening roof system even for relatively large and heavy covers, such as those weighing over 20 kg (approximately 22 kg or more). Furthermore, highly tapered or trapezoidal first covers can be used, as the two parallel guide rails conventionally required in the rear section next to the second and third covers are not necessary.The hinge mechanism allows for a sufficiently large lifting and lowering of the first cover along the vertical axis Z, enabling the extension carriage to be guided beneath the second and third covers, where the guide rail is also located. This allows for a visually appealing and aesthetically pleasing design. The elements of the assembly, particularly the components of the hinge mechanism, remain engaged throughout the entire sliding movement of the first cover and are always at least indirectly connected to the frame. This results in a robust assembly that remains stable and durable even in the event of an accident.

[0013] The articulated mechanism, comprising at least seven pivot joints, allows for raising, lowering, and sliding of the first cover, particularly at its trailing edge, without the need for cam guides to pivot levers. The pivot joints are significantly more robust, have lower friction, and are less prone to wear than conventional cam guides. This articulated mechanism with at least seven pivot joints thus enables particularly smooth operation and reliably defined forces during the pivoting movement.

[0014] According to one embodiment, the arrangement comprises a first lever, a second lever, a third lever, and a fourth lever. The first, second, third, and fourth levers are coupled to each other and to the raising and lowering carriages by means of five of the seven pivot joints. For example, one of the levers is coupled to a sixth pivot joint and a drive mechanism. For example, one of the levers is coupled to the first cover by a seventh pivot joint. This lever can also be referred to as the raising and lowering lever. For example, pivoting the fourth lever, which is pivotally connected to the cover by means of the seventh pivot joint, causes the trailing edge of the first cover to rise and fall along the vertical direction.

[0015] The articulated mechanism allows, in particular, that higher leverage forces can be achieved at the beginning and end of the movement for pivoting the fourth lever, and higher movement speeds in between. This is especially possible with a constant drive speed, for example, a constant speed of the extension carriage. The respective end position at the beginning and end of the movement can be reliably reached and held as desired. In particular, the articulated mechanism enables sufficiently high closing forces when closing at high speeds. A larger lid area, for example, or a larger lid mass, requires higher closing forces. Pivoting the fourth lever can be achieved with comparatively low drive forces and, in particular, with known drive forces.Furthermore, the joint mechanics allow for good stiffness of the arrangement along the transverse direction.

[0016] For example, the first lever is pivotally connected to a drive unit via a first joint. The drive unit includes, for example, a drive carriage which is connected to an electric motor via a rigid drive cable. The drive motor's energy is transferred to the first lever via the drive unit, causing it to be moved and pivoted along the longitudinal direction relative to the guide rail. The extension carriage is also moved along the longitudinal direction.

[0017] The first lever, for example, is displaced relative to the frame and pivoted around the first joint. This drives the respective pivoting movements of the other levers, in particular the second, third, and fourth levers. Specifically, it is thus possible to use the drive that pivots the first lever to cause the fourth lever to pivot relative to the frame, thereby raising and lowering the trailing edge of the first cover along the vertical direction.

[0018] According to one embodiment, the second lever is pivotally connected to the first lever and pivotally connected to the extension carriage. For example, the second lever is pivotally connected to the first lever by means of a second pivot joint in the joint mechanism. The lever is pivotally connected to the extension carriage, for example, by means of a third pivot joint.

[0019] According to another embodiment, the third lever is pivotally connected to the second lever. The third lever is, for example, pivotally connected to the fourth lever. For example, the third and second levers are pivotally connected to each other by means of a fourth pivot joint. The third and fourth levers are pivotally connected to each other, for example, by means of a fifth pivot joint.

[0020] According to one embodiment, the fourth lever is pivotably connected to the raising carriage. For example, the fourth lever is pivotably connected to the first cover. For example, the fourth lever is pivotably connected to the raising carriage by means of a sixth pivot joint. For example, the fourth lever and the first cover are pivotably connected to each other by means of a seventh pivot joint.

[0021] It should be noted that the numbering of the pivot joints serves only for identification and does not imply a fixed assignment of the pivot joints to the levers. A different coupling sequence of the four levers is also possible. For example, the second and fourth levers may each be connected to the extension carriage by means of a corresponding pivot joint, with the respective pivot joints being fixed to the extension carriage. Alternatively, the third and fourth levers may be pivotally connected to the extension carriage by means of two corresponding pivot joints. Two of the four levers, for example, the second and fourth levers, each have a connection to three pivot joints. The other two of the four levers, for example, the first and third levers, have a connection to two pivot joints each.A swivel joint connects, in particular, two of the levers to each other or one of the levers to another element, for example, the drive, a slider, or the extension carriage. The numbering of the levers also serves to distinguish them from one another and does not represent a mandatory assembly sequence or sequence of operation.

[0022] The arrangement with the four levers and the seven pivot joints thus forms a seven-joint mechanism. The four levers are coupled such that when the extension carriage, and therefore the first lever, is moved longitudinally, the fourth lever pivots, thereby raising and lowering the trailing edge of the first cover. The pivoting of the fourth lever serves, in particular, to raise and lower the trailing edge of the first cover along the vertical direction. The arrangement can be driven by a single drive, especially by a single electric motor.

[0023] During the movement of the first cover along its longitudinal axis relative to the second and third covers, the first and fourth levers, for example, move along the longitudinal axis midway between the second and third covers. It is also possible to form the second and third covers together as a single piece, so that the joint in which the two levers can move during the movement of the first cover does not run completely between the second and third covers along their longitudinal axis, but is only connected in a front and rear section, and not separated from each other.

[0024] In the open position, the first cover is shifted as far back as possible and the roof opening in the front part is maximally opened.

[0025] According to one embodiment, the arrangement has a fifth and a sixth lever. The arrangement has at least two additional pivot joints. The two additional levers serve, in particular, to pull the coupling between the first and fourth levers apart along the longitudinal direction. This allows, for example, installation space to be saved along the transverse direction, and the two levers—the first and fourth—can be guided more easily and with less space between the second and third covers. The pivoting mechanism for the six levers is designed, for example, as a deca-joint.

[0026] For example, the fifth lever is pivotally connected to the first lever. The fifth lever and the extension carriage are pivotally connected to each other. For example, the fifth and sixth levers are pivotally connected to each other. The sixth lever is also pivotally connected to the second lever. Thus, pivoting the first lever via the fifth and sixth levers can be transferred to the second lever, and therefore also to the third and fourth levers.

[0027] According to one embodiment, in a closed position of the arrangement, the end of the first lever facing the first cover and the end of the fourth lever facing the first cover are spaced further apart along the first direction than in an open position of the arrangement. In particular, the first pivot joint, which pivotally connects the first lever to the drive, and the seventh pivot joint, which pivotally connects the fourth lever to the first cover, are spaced further apart in the closed position than in the open position.

[0028] According to another embodiment, the end of the first lever facing the first lid is positioned closer to the end of the fourth lever facing the first lid in the closed position than in the open position. In particular, when the first lever is pulled forward longitudinally to extend the fourth lever, the two ends are closer together in the closed position than in the open position. In embodiments where the first lever is moved backward longitudinally to pivot the fourth lever from the closed position, the two ends are closer together in the open position than in the closed position.

[0029] According to at least one embodiment, a vehicle roof has an arrangement according to at least one of the embodiments described here. For example, the vehicle roof has a roof opening into which the arrangement is inserted. The roof opening of the vehicle roof is closed by means of the arrangement. The roof opening can be strongly tapered or trapezoidal. The arrangement with the centrally positioned guide rail allows for the appropriate design of the first, second, and third covers, while reliably supporting the sliding first cover. The hinge mechanism enables the use of even comparatively heavy and / or large covers and provides sufficient vertical stroke to reliably slide the first cover above the second and third covers along the longitudinal direction.

[0030] Further advantages, features, and developments will emerge from the following examples, explained in conjunction with the figures. Identical, similar, and equivalent elements can be represented across figures using the same reference symbols.

[0031] They show:

[0035] Figures 9 to 11 each show schematic representations of the arrangement according to a further embodiment, Figures 12 to 14 each show schematic representations of the

[0036] Arrangement according to a further example,

[0037] Figure 15 shows a schematic representation of a sectional view of the arrangement according to an exemplary embodiment.

[0038] Figures 16 and 17 each show schematic representations of a part of the arrangement according to a further embodiment, and

[0039] Figures 18 and 19 each show schematic representations of part of the arrangement according to a further embodiment.

[0040] Figure 1 shows a schematic top view of a vehicle 100. The vehicle 100 is, for example, a passenger car. The vehicle 100 has a vehicle roof 101. The vehicle roof 101 has an arrangement 109. The arrangement 109 has a first cover 110, a second cover 120, and a third cover 130.

[0041] For example, the second cover 120 and the third cover 130 are formed separately from each other. According to further embodiments, the second cover 120 and the third cover 130 are formed by means of a single common cover.

[0042] A roof opening 104 of the vehicle roof 101 can be closed by means of the covers 110, 120, 130 and the arrangement 109. By sliding the first cover 110 along a longitudinal direction X, the roof opening 104 can be closed in a closed position and at least partially freely moved in an open position. The closed position can also be referred to as the locked position. The open position can also be referred to as the open position.

[0043] The first cover 110 is displaceable along the longitudinal direction X and a transverse vertical direction Z between the closed position, shown in Figure 1, and an open position relative to a fixed roof section of the vehicle roof 101. To close, the first cover 110 is moved opposite to the longitudinal direction X.

[0044] The first cover 110 has a leading edge 111. The first cover 110 has a trailing edge 112. The leading edge 111 and the trailing edge 112 are arranged opposite to each other along the longitudinal direction X. The leading edge 111 of the first cover 110 faces a windshield 103 of the vehicle 100. The trailing edge 112 of the first cover 110 faces the second cover 120 and the third cover 130. The trailing edge 112 of the first cover 110 faces a rear window 102 of the vehicle 100.

[0045] Between the front edge 111 and the rear edge 112, which each extend along a transverse direction Y, two side edges 113 of the first cover 110 are arranged. The side edges 113 each extend in a principal extension direction along the first direction X between the front edge 111 and the rear edge 112 of the first cover 110.

[0046] The second cover 120 and the third cover 130 each have leading edges 121 and 131, respectively. The leading edges 121 and 131 of the second cover 120 and the third cover 130 each face the windshield 103 and, in the closed position, face the trailing edge 112 of the first cover 110. The leading edges 121 and 131 extend along the transverse direction Y. In the closed position, the second cover 120 and the third cover 130 are each positioned between the first cover 110 and the rear window 102. The second cover 120 and the third cover 130 are arranged side by side along the transverse direction Y. The second cover 120 has a side edge 122. The side edge 122 extends along the longitudinal direction X. The side edge 122 faces the third cover 130.

[0047] The third cover 130 has a side edge 132. The side edge 132 runs along the longitudinal direction X. The side edge 132 faces the second cover 120.

[0048] The side edge 122 of the second cover 120 and the side edge 132 of the third cover 130 are adjacent to each other and spaced apart along the transverse direction Y. A gap is arranged between the two side edges 122 and 132, which is sealed by a gasket 160. For example, the gasket 160 has two partial seals, one of which is connected to the second cover 120 and the other to the third cover 130. The gasket 160 extends along the longitudinal direction X between the second cover 120 and the third cover 130.

[0049] The second cover 120 and the third cover 130 are each in particular rigidly and permanently connected to the vehicle roof 101 and immovably attached to the vehicle roof 101.

[0050] Location details and / or used in this disclosure

[0051] Directional terms such as "rear" or "front" refer to the vehicle's longitudinal direction X, particularly in the intended installation state of the arrangement 109 in the vehicle roof 101. The longitudinal direction X can also be referred to as the vehicle's longitudinal direction and / or the X-direction. Corresponding location and / or direction terms, such as "above" or "below," refer to the vertical direction Z. The vertical direction Z can also be referred to as the vertical direction or Z-direction. Location and / or direction terms used, such as "side" or "left" or "right," refer to the transverse direction Y, which can also be referred to as the vehicle's transverse direction and / or Y-direction. The longitudinal direction X, the transverse direction Y, and the vertical direction Z are each, in particular, perpendicular to one another.

[0052] Figure 2 shows a schematic representation of part of the arrangement 109. Figure 2 shows a frame 105 by means of which the first cover 110, the second cover 120, and the third cover 130 can be attached to the vehicle 100. The frame 105 has two lateral guide rails 106 in a front region. The two lateral guide rails 106 are arranged in a front region of the frame 105 facing the windshield 103 and each extends longitudinally along the longitudinal direction X.

[0053] A guide rail 140 is arranged in a rear area of ​​the frame 105. The guide rail 140 is arranged in a central area 118, which runs in the area of ​​the two side edges 122, 132.

[0054] The first lid 110 is attached at its rear edge 112 at the

[0055] Guide rail 140 supported. The raising and lowering of the first cover 110 along the vertical direction Z relative to the frame 105 and to the guide rail 140 is carried out by means of a joint mechanism 300, which is guided and supported in the guide rail 140.

[0056] The first cover 110 is guided and supported laterally at its front edge 111 in the two lateral guide rails 106.

[0057] The first cover 110 is thus supported at three points. In a front area 116, which adjoins the front edge 111 and extends along the longitudinal direction X to a maximum of 50% of the first cover 110, the first cover 110 is supported on the two lateral guide rails 106. In a rear area 117, which adjoins the rear edge 112 and extends from the rear edge 112 towards the front edge 115 to a maximum of 50% of the first cover 110, the first cover 110 is supported on the guide rail 140.

[0058] The guide rail 140 is rigidly fixed to the remaining frame 104 and, in particular, cannot be displaced, raised, or lowered relative to the remaining frame 105. The hinge mechanism 300 serves to raise the first cover 110 from the closed position at its rear edge relative to the guide rail 140 along the vertical direction X and subsequently to move it backwards relative to the guide rail 140 along the longitudinal direction X until the open position is reached. Starting from the open position, the first cover 110 is first moved forwards to close, whereby the hinge mechanism 300 is moved forwards relative to the guide rail 140 along the longitudinal direction X. To assume the closed position, the first cover 110 is lowered along the vertical direction Z, whereby the hinge mechanism 300, in particular, lowers the rear edge 112 of the cover 110 along the vertical direction Z relative to the guide rail 140.

[0059] The joint mechanism 300 is designed, for example, as a reversible joint, as will be explained in more detail with reference to the following figures. The joint mechanism 300 has, for example, four levers 301, 302, 303, 304. The joint mechanism 300 has, for example, seven reversible joints 321, 322, 323, 324, 325, 326, 327. The reversible joints 321 to 327 pivotally connect the four levers 301 to 304 to each other in order to allow the raising and lowering of the trailing edge 112 of the first cover 110. The respective axes of rotation of the reversible joints 321, 322, 323, 324, 325, 326, 327 run along the transverse direction Y.

[0060] Figures 3 to 8 show schematic representations of the joint mechanism 300 according to an exemplary embodiment.

[0061] The joint mechanism 300 comprises four levers 301 to 304, which are coupled to one another by means of seven rotary joints 321 to 327. The joint mechanism 300 also includes an extension slide 307. The extension slide 307 is guided longitudinally in the guide rail 140. In particular, the levers 301 to 304 are pivotable relative to the extension slide 307 and, together with the extension slide 307, are displaceable relative to the guide rail 140 along the longitudinal direction X.

[0062] The joint mechanism 300 is coupled to a drive 108. The drive 108 is configured to exert a drive energy along the longitudinal direction X to the frame 104 in order to cause the four levers 301 to 304 to pivot. For example, kinetic energy from an electric motor is transmitted to the joint mechanism 300 by means of a drive cable 150 of the drive 108.

[0063] Starting from the closed position shown in Figures 3, 5, and 7, the drive 108 is moved to raise the rear edge 112 of the first cover 110, thus pulling the first lever 301 forward along the X-direction. The first lever 301 is pivotably connected to the drive 108 by means of the first pivot joint 321. In particular, the first lever 301 is coupled to the drive 108 at its first end 311, which faces the windshield 103, by means of the first pivot joint 321.

[0064] The movement of the first lever 301 is transmitted to the fourth lever 304 via the further levers 302 and 303, so that it is extended, as shown in Figures 4, 6, and 8. Raising and lowering an end 318 of the fourth lever facing the first cover 110 causes the rear edge 112 of the first cover 110 to be raised and lowered.

[0065] The first lever 301 is pivotably connected to the second lever 301 by means of the second pivot joint 322. The second lever 302 is also pivotably connected to the third lever 303 by means of the third pivot joint 323. Furthermore, the second lever 302 is pivotally connected to the extension carriage 307 by means of the fourth pivot joint 324.

[0066] In addition to the pivotable connection to the second lever 302 via the third pivot joint 323, the third lever 303 is also pivotably connected to the fourth lever 304 via the fifth pivot joint 325. The fourth lever 304 is furthermore pivotally connected to the slider 307 via the sixth pivot joint 326.

[0067] The first pivot joint 321 thus connects the first lever 301 pivotably to the drive 308. The second pivot joint 322 connects the first lever 301 and the second lever 302 pivotably to each other. The third pivot joint 323 connects the second lever 302 and the third lever 303 pivotably to each other. The fourth pivot joint 324 connects the second lever 302 and the extension slide 307 pivotally to each other. The fifth pivot joint 325 connects the third lever 303 and the fourth lever 304 pivotally to each other. The sixth pivot joint 326 connects the third lever 304 and the extension slide 307 pivotally to each other. The seventh pivot joint 327 connects the fourth lever 304 and the first cover 110 pivotably to each other, in particular the fourth lever 304 and a cover support 115 of the first cover 110.

[0068] The first lever 301 and the third lever 303 are each pivotally connected to two of the seven pivot joints 321 to 327. The second lever 302 and the fourth lever 304 are each pivotally connected to three of the seven pivot joints 321 to 327. The extension slide 307 is pivotally connected to two of the levers 301 to 304 by means of two of the seven pivot joints 321 to 327. The second lever 302 and the fourth lever 304 each have a triangular base shape. The third pivot joint 323 is not arranged on a connecting line between the second pivot joint 322 and the fourth pivot joint 324. The sixth pivot joint 326 is not arranged on a connecting line between the fifth pivot joint 325 and the seventh pivot joint 327.In both the closed and open positions, a dead center position is achieved in which the pivot joints 321 to 327 are arranged relative to each other in such a way that external forces cannot cause unwanted pivoting of the fourth lever 304. Thus, the closed and open positions are reliably maintained without requiring any special forces, for example, from the first lever 301. Therefore, in the closed position, for instance, the lid is held securely, and unintentional opening of the lid is reliably prevented. Furthermore, particularly just before the lid closes, when a strong suction effect and resulting forces occur, a large closing force can be transmitted to the lid 110 via the pivot mechanism 304.

[0069] During the movement of the first lever 301 along the longitudinal direction X, the extension carriage 307 is also moved relative to the guide rail 140 along the longitudinal direction X to allow the pivoting of the four levers 301 to 304. Starting from the closed position, the extension carriage 307 is initially moved forward, while the levers 301 to 304 pivot to raise the trailing edge 112.

[0070] To move the first cover 110 rearward along the longitudinal direction X to its maximum open position, the extension carriage 307 is moved rearward along the longitudinal direction X relative to the guide rail 140. This also moves the hinge mechanism 300, in particular the fourth lever 304, rearward along the longitudinal direction X. Closing occurs in the reverse sequence of movements. When the first lever 301 is moved along the longitudinal direction X to extend the rear edge 112 of the first cover 110, the first lever 301 is initially moved forward, increasing the distance between the first pivot joint 321 and the seventh pivot joint 327 along the longitudinal direction X. In the closed position, for example, as shown in Figure 5, the first pivot joint 321 and the seventh pivot joint 327 are positioned closer together along the longitudinal direction X than in the open position, for example, as shown in Figure 6.In the open position, the first pivot joint 321 and the seventh pivot joint 327 are further apart from each other along the longitudinal direction X than in the closed position.

[0071] Figures 9 to 11 show the joint mechanism 300 according to a further embodiment. The embodiment according to Figures 9 to 11 corresponds in its basic functionality to the embodiment according to Figures 3 to 8. In contrast, the first lever 301 is moved from the closed position (Figure 9) to the open position (Figure 10) along the longitudinal direction X rearward in the direction of the rear window 102. This results in different connections of the levers 301 to 304 by means of the pivot joints 321 to 327 than described in connection with Figures 3 to 8.The fundamental operating principle and, in particular, the advantages of the large forces at the beginning and end of the pivoting movement, as well as the long stroke along the vertical direction Z and the dead center position in the closed position, i.e., also in the fully extended position, are the same. Therefore, these and the related details will not be repeated here; instead, the differences will be described primarily. In the embodiment shown in Figures 9 to 11, the drive 108 is designed such that, starting from the closed position according to Figure 9, it moves backward in the longitudinal direction towards the open position according to Figure 10. To move the first cover 110 from the open position to the closed position, the drive 108 moves forward in the opposite direction X. The first lever 301, which is connected to the drive 108 by means of the pivot joint 321, is moved accordingly.

[0072] The first lever 301 and the second lever 302 are pivotably connected to each other by means of the second pivot joint 322. The second lever 302 is pivotably connected to the third lever 303 by means of the third pivot joint 323. The second lever 302 and the extension slide 307 are pivotably connected to each other by means of the fourth pivot joint 324. The third lever 303 is pivotally connected to the fourth lever 304 by means of the fifth pivot joint 323. The fourth lever 304 and the extension slide 307 are pivotably connected to each other by means of the sixth pivot joint 326. The fifth pivot joint 325 is not arranged on a connecting line between the sixth pivot joint 326 and the seventh pivot joint 327.

[0073] Unlike the embodiment shown in Figures 3 to 8, where the sixth pivot joint 326 is arranged along the main extension direction of the fourth lever 304 between the fifth pivot joint 325 and the seventh pivot joint 327, in the embodiment shown in Figures 9 to 11 the fifth pivot joint 325 is arranged along the main extension direction of the fourth lever 304 between the sixth pivot joint 326 and the seventh pivot joint 326. When the first lever 301 is moved in the longitudinal direction X to extend the trailing edge 112 of the first cover 110, the first lever 301 is moved rearward, thus reducing the distance between the first pivot joint 321 and the seventh pivot joint 327 along the longitudinal direction X. In the closed position according to Figure 9, the first pivot joint 321 and the seventh pivot joint 327 are further apart from each other along the longitudinal direction X than in the open position according to Figure 10.In the open position, the first pivot joint 321 and the seventh pivot joint 327 are arranged closer together along the longitudinal direction X than in the closed position.

[0074] Figures 12 to 14 show the arrangement 109 according to a further embodiment. The embodiment according to Figures 12 to 14 is based on the embodiment according to Figures 9 to 11. Therefore, the differences are described below. In addition to the four levers 301 to 304, the embodiment shown below in Figures 12 to 14 has a fifth lever 305 and a sixth lever 306. Furthermore, an eighth pivot joint 328 and a ninth pivot joint 329 are also provided.

[0075] The first lever 301 and the drive 108 are pivotally connected to each other by means of the first pivot joint 321. The first lever 301 is pivotally connected to the fifth lever 305 and the sixth lever 306 by means of the second pivot joint 32. The fifth lever 305 is pivotally connected to the extension carriage 307 by means of the third pivot joint 323. The fifth lever 305 is pivotally connected to the slider 307 and the first lever 301, thus coupling the first lever 301 to the slider 307. The second lever 302 is pivotally connected to the extension carriage 307 by means of the fourth pivot joint 324. The second lever 302 and the third lever 303 are connected to each other by means of the fifth pivot joint 325. The second lever 302 and the sixth lever 306 are connected to each other by means of the sixth pivot joint 326. The third lever 303 is pivotally connected to the fourth lever 304 by means of the eighth pivot joint 328.

[0076] The fourth lever 304 and the extension slide 307 are pivotally connected to each other by means of the ninth pivot joint 329. The fourth lever 304 and the first cover 110 are pivotally connected to each other by means of the seventh pivot joint 327. The movement of the drive 108 is transmitted to the second lever 302 by means of the first lever 301, the fifth lever 305, and the sixth lever 306, each of which is connected by two associated pivot joints. The movement of the second lever 302 is then transmitted to the third lever 303 and the fourth lever 304 as explained above. The fifth lever 305 and the sixth lever 306 allow the first lever 301 and the fourth lever 304 to be arranged further offset from each other along the X-direction than in the embodiment shown in Figures 9 to 11.Thus, the two levers 301, 304 can be guided one after the other in the space between the second cover 320 and the third cover 330 to move the first cover 110 relative to the guide rail 140. Figure 15 shows a sectional view of the arrangement 109 with the hinge mechanism 300 according to one of the previously described embodiments. The guide rail 140 is attached to the frame 105 or is part of the frame 105. In particular, the guide rail 140 is fixedly connected to the frame 105. The second cover 120 and the third cover 130 are also fixedly connected to the frame 105, for example by means of an adhesive bond 161. The guide rail 140, the second cover 120, and the third cover 130 are fixedly fixed to each other and, in particular, arranged so that they are immovable relative to each other.A gap 114 is arranged along the Y-direction between the second cover 120 and the third cover 130, extending along the longitudinal direction X. The gap 114 is sealed by means of the seal 160.

[0077] To move the first cover 110, the fourth lever 304 is displaceable in the gap 114 along the longitudinal direction X relative to the second cover 120 and the third cover 130. In doing so, the fourth lever 304 pushes the flexible and elastic seal 160 apart along the Y direction. After passing the fourth lever 304, the two seal parts 160 move back towards each other, so that the gap 114 is reliably sealed outside the fourth lever 304.

[0078] The fourth lever 304 is supported in the guide rail 140 below the second cover 120 and the third cover 130 by means of the extension slide 307. The fourth lever 304 connects the first lever 110 above the second cover 120 and the third cover 130 to the guide rail 140 below the second cover 120 and the third cover 130. Figures 16 and 17 show the arrangement 109 according to an exemplary embodiment that allows for an electrical connection of the first cover 110. Figure 16 shows the arrangement 109 in the closed position, and Figure 17 shows the arrangement

[0079] 109 in the open position. The embodiment shown in Figures 16 and 17 essentially corresponds to the previous embodiments. In particular, the electrical connection is feasible with various joint mechanisms 300, for example, both with a seven-joint and a ten-joint.

[0080] For example, the first cover 110 has an electric lighting function by means of which the interior of the vehicle 100 can be illuminated. Such lighting is also referred to as ambient lighting in English.

[0081] Alternatively or additionally, the first cover 110 has an integrated electric blackout device. For example, the first cover 110 has a film that tints more or less depending on an electrical voltage. Thus, the degree of light transmission of the first cover 110 is adjustable and variable. This eliminates the need for an additional fabric roller blind, for example.

[0082] Alternatively or additionally, other electrical devices can also be integrated into the first cover 110.

[0083] The electrical device, for example, results in an additional weight of 110 on the first lid. The first lid

[0084] Even with the additional weight, 110 can be reliably moved using the joint mechanism 300, as it is designed as described to realize large forces.

[0085] The device 109 includes a trailing cable 170 to establish the electrical connection. The trailing cable 170 is, for example, a flat cable. The trailing cable 170 has electrically conductive wires. The trailing cable 170 can be connected to an electrical power supply, for example, to the vehicle's electrical system 100, via a connector 171. Control signals can also be transmitted via the trailing cable 170, for example, to control lighting and / or blinds. For example, the trailing cable is connected to a vehicle control system. The trailing cable 170 is connected to the first cover 110 at a cover connection 172 to transmit electrical current and / or control signals to the first cover 110.

[0086] The trailing cable 170 runs in the guide rail 140 between the second cover 120 and the third cover 130. This allows the trailing cable 170 to be positioned in a space-saving manner. Furthermore, the trailing cable 170 is always located below the seal 160, with the exception of the cover connection 172 and a section that runs along the fourth lever 304. Thus, the trailing cable 170 is largely or only barely visible from the outside. In addition, the trailing cable 170 is not exposed to strong wind forces during operation, so that flapping of the trailing cable 170 and the associated noise emissions are avoided.

[0087] The trailing cable 170 is arranged in the joint mechanism 300 on the fourth lever 304. The trailing cable 170 runs along the fourth lever 304 between the guide rail 140 and the first cover 110. For example, the

[0088] Towing cable 170 is attached to the fourth lever 304.

[0089] The trailing cable 170 reliably follows the movement of the fourth lever 304 in the area of ​​the joint mechanism 300.

[0090] Figures 18 and 19 show the arrangement 109 according to an exemplary embodiment. The exemplary embodiment of Figures 18 and 19 corresponds to the previous exemplary embodiments. The exemplary embodiment according to Figures 18 and 19 concerns the drive of the drive cables 150 (Figure 3), which can be implemented with various joint mechanisms 300, for example, both with the seven-joint and the ten-joint. Figure 18 shows the arrangement 109 in the closed position and Figure 19 shows the arrangement 109 in the open position.

[0091] Two guide tubes 181 are attached to the first cover 110. For example, the guide tubes 181 are attached to a disc of the first cover 110. The guide tubes 181 each extend from the front edge 111 to the rear edge 112 along the side edge 113, for example in a respective lateral cover support 182. At the rear edge 112, the two guide tubes 181 extend along the rear edge 112 to the hinge mechanism 300.

[0092] The drive cables 150 are slidably guided in the guide tubes 181. The guide tubes 181 and the drive cables 150 thus move together with the first cover 110 when the latter is moved relative to the guide rail 140 along the longitudinal direction X.

[0093] The drive cables 150 are each coupled to a drive in the area of ​​a front extension mechanism 180. For example, the front extension mechanism 180 is driven by an electric motor, so that the drive energy of the electric motor can be transferred to the front extension mechanism 180 and to the drive cables 150, and thus to the joint mechanism 300. In particular, further drive cables, not explicitly shown, are provided for this purpose, which run between the electric motor and the front extension mechanism 180 in order to transfer the drive energy from the electric motor to the front extension mechanism 180.

[0094] The joint mechanism 300 is coupled to the front tilting mechanism 180 by means of the drive cables 150 to enable the active pivoting of the fourth lever 304, in order to raise and lower the rear edge 112 of the first cover 110 by means of the drive cables 150. The front tilting mechanism 180 is designed to raise and lower the front edge 111 and to move the first cover 110 along the longitudinal direction X.

[0095] The guide tubes 181 are moved together with the first cover 110 so that, in the open position, the roof opening 104 is unobstructed by the guide tubes 181. The guide tubes 181 are arranged along the longitudinal direction X in the area of ​​the lateral guide rails 106. Thus, the viewing area of ​​the first cover 110 is not obstructed by the guide tubes 160 in the closed position. The drive cables 150 each run along the longitudinal direction X on one of the side edges 113 of the first cover 110 and along the transverse direction Y on the rear edge 112 of the first cover. In the central area 118, the drive cables 150 again run along the longitudinal direction X to move the first lever 301 along the longitudinal direction X. To raise the rear edge 112 from the closed position, the front tilting mechanism 180 moves backwards along the longitudinal direction X relative to the side guide rails 106.Thus, the drive cables 150 are also shifted to the rear. Due to the deflection of the drive cables 150 by a total of 180°, the drive cables 150 shift forward along the longitudinal direction X at the end connected to the joint mechanism. This pulls the first lever 301 forward, specifically the first end 311 of the first lever 301. The fourth lever 304 is then pivoted by means of the levers of the joint mechanism 300, thereby raising the rear edge 112 along the vertical direction Z relative to the guide rail 140. When the fourth lever 304 is fully extended, the drive cables 150 lock into the front extension mechanism 180, so that the fourth lever 304 is reliably held in the extended position.By means of further drive cables, not explicitly shown, the front opening mechanism is moved further relative to the lateral guide rails 106 in order to raise the front edge 111 of the first cover 110 and subsequently move the first cover 110 backwards along its longitudinal direction relative to the guide rail 140 into the open position. The closing movement from the open position proceeds in reverse order.

[0096] The arrangement 109, according to the various embodiments, allows the fourth lever 304 to pivot using only rotary joints, thus avoiding the need for cam guides. The components of the joint mechanism 300, in particular the levers 301 to 304 and the levers 301 to 306, are only pivotable relative to each other, and translational movement is not permitted at the connection points. The rotary joints 321 to 329 each allow pivoting and prevent displacement or translational movement. This allows for comparatively small torques to overcome the bearing friction in the rotary joints 321 to 329, even under higher loads. This bearing friction is significantly lower than the friction in a cam guide.

[0097] During movement from the open to the closed position, particularly towards the end of the closing movement, high forces can occur due to wind load and seal pressure, leading to a higher drive force requirement for the final closing of the first cover 110. This is compensated for by the transmission provided by the seven-joint mechanism. The comparatively large travel of the drive 108 and the end 311 of the first lever 301 against the longitudinal direction X relative to the guide rail 140 only needs to cause a small pivoting of the fourth lever 304 towards the closed position. Thus, a large force can be applied against the upward direction Z to the rear area 117 of the first cover 110 to pull the first cover 110 into its final closed position.

[0098] Only a single electric motor is used to move the cover, i.e., to raise and lower it along the vertical direction Z and to move it along the longitudinal direction X. The arrangement of the guide rail 140, in which the first cover 110 is supported with its rear section 117, in the central section 118 allows for any desired outer contour, particularly for the second cover 120 and the third cover 130, since no external, parallel guide rails are required in the rear section. The components of the hinge mechanism 300 are permanently engaged with each other; in particular, no decoupling and coupling occurs as in cam mechanisms. This results in a high degree of robustness for the hinge mechanism 300.Furthermore, the desired aesthetic can be achieved because the two rear covers 120, 130 can be arranged very close together along the Y-direction, leaving only a small gap 114 for the passage of levers 301, 304. The arrangement 109 enables reliable, low-friction, and energy-efficient pivoting of the fourth lever 304.
