Description

[0001] An arrangement for a vehicle roof is specified, in particular an arrangement for moving a cover to close a roof opening of 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.

[0002] 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 C1. 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 A1.

[0003] 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.

[0004] The disclosure relates to an arrangement for a vehicle roof. In particular, the arrangement is designed to move a cover along a first direction relative to a guide rail. The guide rail can, for example, be mounted on the vehicle roof. By moving the cover, it is possible to selectively open and close a roof opening of the vehicle roof.

[0005] The guide rail extends elongated along the first direction. The arrangement includes a control rod that extends elongatedly along the first direction. The control rod has a first end and a second end opposite the first direction. The arrangement includes a steering lever. The steering lever is coupled to the guide rail. The steering lever is coupled to the guide rail in such a way that it is fixed relative to the guide rail and pivotable. The arrangement includes an extension lever. The extension lever is pivotably coupled to the guide rail. In particular, the extension lever is fixedly coupled to the guide rail and pivotable.

[0006] The control rod is pivotally coupled to the steering lever at its first end. The control rod is pivotally coupled to the extension lever at its second end. The coupling of the control rod to the steering lever and the extension lever is designed such that pivoting the steering lever is transmitted as a pivoting of the extension lever. Pivoting the steering lever relative to the guide rail about an axis of rotation oriented transversely to the first direction along a second direction results in a displacement of the control rod relative to the guide rail along the first direction. This displacement of the control rod then pivots the extension lever relative to the guide rail about an axis of rotation oriented along the second direction.

[0007] The movement of the control rod is effected by the steering lever. This lever does not need to be moved in cam tracks or shifted along the guide rail in the first direction to move and lock the control rod. The movement of the control rod is achieved through rotary or pivoting movements of the steering lever. Locking the control rod relative to the guide rail is also reliably possible, particularly since the coupling between the control rod and the steering lever does not involve cam tracks.

[0008] For example, the arrangement includes a cover designed to close a roof opening in the vehicle roof. In a closed position, the cover seals the roof opening. In an open position, the roof opening is at least partially uncovered. The cover is movable relative to the rest of the vehicle roof along the first direction between the closed and open positions. Additionally, the cover can be raised and lowered along a third direction, which can also be described as the upward direction. Raising and lowering is made possible, in particular, by means of the release lever.

[0009] A lid support is coupled to the opening lever, so that pivoting the opening lever raises or lowers the lid support and thus the lid. The lid is displaceable relative to the opening lever along its length relative to the guide rail. This arrangement is thus formed, for example, by a so-called spoiler roof. The opening lever can also be referred to as the rear opening lever.

[0010] Starting from the closed position, the control rod is moved towards the tilt lever by pivoting the steering lever relative to the guide rail. This pivots the tilt lever, lifting a rear section of the lid. Once the tilt lever is fully extended, the control rod locks relative to the guide rail to reliably hold the tilt lever in its extended position. From the closed position, the lid has, for example, reached its tilt position, where the rear edge of the lid is already tilted along the vertical axis, but the front edge of the lid is not yet significantly raised.

[0011] Starting from the tilt position, the front edge can be lifted and the lid moved relative to the guide rail in the first direction into the open position, with the lid being moved relative to the tilt lever. The control rod remains locked relative to the guide rail during this movement. The closing movement, from the open position to the closed position, occurs in reverse order.

[0012] The steering lever is positioned to lock the control rod, particularly in an over-center position, from which it can only be released by an external force. Forces that would otherwise occur during operation in the tilt position and / or the open position, for example, those exerted on the steering lever by the release lever and the control rod, cannot move the steering lever out of this over-center position. Thus, the control rod is reliably locked relative to the guide rail by means of the steering lever. The release lever is therefore reliably held in its extended position.

[0013] According to one embodiment, the arrangement has a first pivot joint that is fixed in position relative to the guide rail. For example, the first pivot joint is fixed in position on the guide rail. For example, the first pivot joint is fixed in position on a reinforcement of the guide rail. The reinforcement is, for example, partially surrounded by a plastic material, with guide tracks and / or guide channels being formed by means of the plastic material.

[0014] The steering lever and the guide rail are pivotally coupled to each other via the first pivot joint. For example, the steering lever is pivotally fixed to the guide rail by means of the first pivot joint. The pivot joint enables the steering lever to be coupled to the guide rail in a fixed and pivotable position. In particular, only pivoting is possible, and no movement along the longitudinal direction. Translation is prevented by the pivot joint.

[0015] According to one embodiment, the arrangement has a second pivot joint that is fixed to the steering lever. The steering lever and the control rod are pivotably coupled to each other by means of this second pivot joint. This second pivot joint allows the steering lever and the control rod to pivot freely together, thus preventing translation.

[0016] The two pivot joints enable the transmission of the steering lever's pivoting motion via the control rod to the extension lever. These pivot joints allow for high force transmission. In particular, they can absorb high forces along the first direction. Specifically, greater forces can be transmitted via the pivot joints than via cam guides, especially at the beginning and end of the pivoting movement of the steering lever and the extension lever.

[0017] According to one embodiment, the arrangement features a joint mechanism. The control rod and the opening lever are coupled to each other by means of this joint mechanism. The joint mechanism has at least four additional pivot joints. In particular, the joint mechanism is designed, for example, as a four-bar linkage, a seven-bar linkage, or another multi-link system. The arrangement with the steering lever, the control rod, and the joint mechanism thus allows the opening lever to pivot by means of the numerous pivot joints without the need for cam guides. This allows comparatively high forces to be transmitted. During the pivoting movement, the necessary forces can be reliably transmitted. Therefore, for example, a less powerful electric motor can be used to drive the steering lever while keeping the lid the same size, or a heavier lid can be used while keeping the electric motor the same size.For example, the joint mechanism has three levers that are arranged between the control rod and the extension lever and are coupled to each other to transfer the movement of the control rod into the pivoting of the extension lever.

[0018] According to one embodiment, the arrangement includes a retaining element. The retaining element is connected to the guide rail to hold the steering lever in a predetermined position. Specifically, the predetermined position is the over-center position of the steering lever, in which the steering lever locks the control rod relative to the guide rail. In the predetermined position of the steering lever, the release lever is in its pivoted position, and the cover is in the tilt position and / or the open position. For example, the retaining element includes a spring. The retaining element exerts an additional force on the steering lever, which holds the steering lever in the over-center position. This provides additional protection against tampering and / or vibration.

[0019] According to one embodiment, the control rod has a retaining pin. The retaining pin engages with the locking element in a predetermined position of the control rod to hold it in this position. Specifically, the predetermined position of the control rod corresponds to the position in which the control rod is locked relative to the guide rail. The predetermined position of the steering lever, in which the locking element holds the steering lever, and the predetermined position of the control rod, in which the locking element holds the control rod, are mutually dependent and occur simultaneously. The locking element is thus designed to hold both the steering lever and the control rod in their respective predetermined positions. Therefore, the control rod is reliably held in the locked position, and reliable protection against tampering and / or vibration is achieved.

[0020] According to one embodiment, the arrangement includes a drive carriage. The drive carriage is coupled to the electric motor, for example, by means of a drive cable that is stiff in both tension and compression. The drive carriage is displaceable along the first direction relative to the guide rail. The drive carriage has a drive cam. The control rod has a drive pin. The drive pin is guided in the drive cam. By moving the drive carriage, a pivoting of the control rod and a pivoting of the steering lever are thus driven. During the movement of the drive carriage, the drive pin is moved along the drive cam, thereby driving the pivoting of the control rod. The drive cam is designed, in particular, such that it can rotate the steering lever out of the locked position in the over-center position.The drive mechanism is shaped in such a way that it can exert a force along the upward direction on the control rod and thus on the steering lever.

[0021] According to one embodiment, the retaining pin and the drive pin spring forward in opposite directions over the control rod. For example, the retaining pin springs forward in the opposite direction over the control rod, and the drive pin springs forward in the second direction over the control rod.

[0022] According to one embodiment, the drive cam has an open end, allowing the drive pin to be disengaged from and engaged in the drive cam. Starting from the closed position, the drive pin is initially guided in the drive cam until the steering lever reaches the locked position. Subsequently, the drive carriage moves further away from the steering lever in the first direction. During this movement, the drive pin exits the drive cam at its open end. To rotate the steering lever out of the over-center position, the drive pin engages with the drive cam at its open end when the drive carriage is moved towards the steering lever in the first direction relative to the guide rail.

[0023] The disclosure relates to a vehicle roof for a motor vehicle. The vehicle roof has an arrangement according to at least one of the embodiments described herein. The vehicle roof has, for example, a roof opening into which the arrangement is inserted. The cover serves to close the roof opening. By means of the arrangement, the cover is movable relative to the vehicle roof. The arrangement, which in particular includes the pivot joints for moving the control rod, enables the use of comparatively heavy or large covers. Accordingly, a comparatively large roof opening can be realized in the vehicle roof.

[0024] Further advantages, features, and developments will emerge from the following examples, which are explained in connection with the figures. Identical, similar, and equivalent elements can be marked with the same reference symbols across different figures.

[0025] They show: Fig. 1 a schematic representation of a part of a vehicle according to an exemplary embodiment, and Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. 9 each schematic representation of an arrangement according to an exemplary embodiment in different views.

[0026] Fig. Figure 1 shows a schematic representation of the roof 101 of a vehicle 100. The vehicle 100 is, for example, a passenger car. The vehicle roof 101 has a roof opening 102. A cover 103 serves to close the roof opening 102. By sliding the cover 103 along a first direction, also referred to as the longitudinal direction X, the roof opening 102 can be closed in a closed position and at least partially opened in an open position. The cover 103 is designed to slide along the longitudinal direction X and a vertical direction Z perpendicular to it between the closed position, which is shown in Figure 103. Fig. Figure 1 shows the cover 103, which is movable in an open position relative to the fixed roof of the vehicle roof 101. To close it, the cover 103 is moved in the opposite direction X.

[0027] The cover 103 has a leading edge 106 and a trailing edge 107. The trailing edge 107 is arranged along the longitudinal direction X opposite to the leading edge 106 of the cover 103. The leading edge 106 of the cover 103 faces a windshield 104 of the vehicle 100. The trailing edge 107 faces a rear window of the vehicle 100. The leading edge 106 and the trailing edge 107 each extend along a transverse direction Y. The longitudinal direction X (first direction), the transverse direction Y (second direction), and the vertical direction Z (third direction) are each perpendicular to each other.

[0028] In this disclosure, location and / or direction specifications such as rear or front refer to the longitudinal direction X, particularly in the intended installation state of the arrangement 110 in the vehicle roof 101. The longitudinal direction X can also be referred to as the vehicle longitudinal direction and / or the X-direction. Corresponding location and / or direction specifications 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 specifications such as side, left, or right refer to the transverse direction Y, which can also be referred to as the vehicle transverse direction and / or Y-direction.

[0029] The arrangement 100 has two guide rails 111. The guide rails 111 each extend elongated along the longitudinal direction X. The guide rails 111 are each arranged along the transverse direction Y next to the roof opening 102. The guide rails 111 are, for example, each coupled to a body of the vehicle 100.

[0030] The arrangement 110 is, in particular, identical on both sides of the roof opening 101, specifically mirrored and corresponding to each other. Therefore, one side is described below, and the opposite side along the transverse direction Y is constructed in a correspondingly similar manner.

[0031] Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. Figure 7 shows the arrangement 110 in different states.

[0032] Fig. 2 and Fig. Figure 5 shows the closing position of the cover 103, in which the cover 103 closes the roof opening 102.

[0033] Fig. 4 and Fig. Figure 7 shows a state in which, in particular, the rear edge 107 is raised along the vertical direction Z compared to the closed position and is arranged above the rest of the vehicle roof 101.

[0034] Fig. 3 and Fig. 6 show a state that is between the state according to Fig. 2 and Fig. 5 and the condition according to Fig. 4 and Fig. 7 is.

[0035] The arrangement 110 includes a control rod 112. The control rod 112 extends longitudinally along the longitudinal direction X between a first end 113 and a second end 114. The control rod 112 is made, for example, of sheet metal, metal and / or plastic.

[0036] The arrangement 110 includes a steering lever 120. The steering lever 120 is fixedly mounted on the guide rail 111 by means of a first pivot joint 121. The first pivot joint 121 allows pivoting about an axis of rotation aligned along the transverse direction Y. Thus, the steering lever 120 can be pivoted relative to the guide rail 111.

[0037] The steering lever 120 and the control rod 112 are connected to each other by means of a second pivot joint 122. The second pivot joint 122 allows the steering lever 120 and the control rod 112 to pivot relative to each other about an axis of rotation oriented along the transverse direction Y. The steering lever 120 extends, in particular, between the first pivot joint 121 and the second pivot joint 122. The steering lever 120 is not translationally displaceable along the longitudinal direction X relative to the guide rail 111. The first pivot joint 121 only allows pivoting movement between the steering lever 120 and the guide rail 111.

[0038] The second pivot joint 122 does not, in particular, allow any translational displacement of the steering lever 120 and the control rod 112 relative to each other, for example along the longitudinal direction X. The second pivot joint 122 only allows the guide rail 111 and the steering lever 120 to pivot relative to each other.

[0039] The second pivot joint 122 is arranged at the first end 113 of the control rod 112. The first end 113 of the control rod 112 faces the leading edge 106 of the cover 103, particularly in the closed position. The first end 113 of the control rod 112 always faces a leading end 117 of the guide rail 111. The leading end 117 faces the windshield 104 along the longitudinal direction X.

[0040] In a region of the guide rail 111 facing away from the front end 117 along the longitudinal direction X, an extension lever 130 is arranged. The extension lever 130 is pivotably coupled to the guide rail 111. In particular, the extension lever 130 is rotatably fixed to the guide rail 111 by means of a pivot joint 204.

[0041] At an end opposite the pivot joint 204, a lid slider 131 is pivotably mounted on the opening lever 130. A lid support 108 of the lid 103 is held in the lid slider 131 and guided for displacement along the longitudinal direction X. Between the closed and open positions, the lid 103 is guided in the lid slider 131 and displaced relative to the opening lever 130 along the longitudinal direction X. The opening lever 131 is held fixed relative to the guide rail 111 and does not move into the open position together with the lid 103 along the longitudinal direction X. Thus, the arrangement 110 is movable in the manner of a spoiler roof.

[0042] The control rod 112 is coupled to the extension lever 130 at its second end 114. For example, the coupling has a joint mechanism 200. The joint mechanism has, for example, four or more pivot joints 201 to 206. The joint mechanism 200 has, for example, two levers arranged between the control rod 112 and the extension lever 130. For example, a movement of the control rod 112 is transmitted to a first of these levers, so that this lever, which is held, for example, by the joint 203 on the guide rail 111 or a component of the guide rail 111, pivots relative to the guide rail. This pivots the second of the levers, which is connected, for example, by the pivot joint 205 to the extension lever. Thus, a movement of the control rod 112 can be transmitted to the extension lever 130 by means of the joint mechanism 200.For example, the joint mechanism 200 is realized according to one of the embodiments described in German patent application 102024111959.4.

[0043] The control rod is pivotably connected at its second end 114 to a lever of the joint mechanism 200 by means of the swivel joint 201. The control rod 112 is at least indirectly pivotably coupled at its second end 114 to the release lever 130 by means of the swivel joint 201.

[0044] To raise the rear edge 107 of the lid 103 from the closed position, the opening lever 130 is pivoted from its retracted position to its extended position. Starting from the closed position, the control rod 112 is moved rearward along the longitudinal direction X away from the front end 107. This causes the opening lever 130 to pivot and thus raise the rear edge 107.

[0045] The movement of the control rod 112 is driven, for example, by an electric motor (not explicitly shown). The drive energy of the electric motor is transmitted, for example, by means of drive cables (not explicitly shown) that are stiff in tension and compression to a drive carriage 160. The drive carriage 160 is guided in the guide rail so as to be displaceable along the longitudinal direction X relative to the guide rail 111.

[0046] The drive carriage 160 has a drive cam 161. The drive cam 161 has an open end 162 facing the front end 117. In the longitudinal direction X, the drive cam 161 extends from the open end 162 initially in a roughly straight line, then inclined, and finally approximately along the vertical direction Z.

[0047] The control rod 112 has a drive pin 116, which is used, for example, in the Fig. 5 and Fig. Figure 6 is shown schematically. The drive pin 116 jumps forward along the transverse direction Y over the control rod 112.

[0048] The drive pin 116 and the drive cam 161 can work together to pivot the control rod 112, for example around the swivel joint 201, and to move it along the longitudinal direction X relative to the guide rail 101.

[0049] In the closed position, the drive pin 116 is located approximately at the transition between the inclined area and the area of ​​the drive cam 161 aligned along the vertical direction Z. The steering lever 120 is inclined slightly forward. The control rod 112 is also inclined slightly; in particular, its front end 113 is spaced apart from the guide rail 111 along the vertical direction Z.

[0050] Starting from the closed position according to Fig. 2 and Fig. 5 The drive carriage 160 moves along the longitudinal direction X towards the extension lever 130, as for example in the Fig. 3 and Fig. Figure 6 is shown as an example of a state. The movement of the drive pin 116 in the drive cam 161 has caused the control rod 112 to be displaced rearward along the longitudinal direction X. The steering lever 120 has also been pivoted rearward about the first pivot joint 121, so that the steering lever 120 is inclined obliquely backward, while the drive pin 116 is guided in the oblique course of the drive cam 161.

[0051] In the further course of movement, in which the drive carriage 160 is moved further rearward along the longitudinal direction X, the drive pin 116 moves in the drive cam 161 towards the open end 162 and thus along the vertical direction Z towards the guide rail 111. During this process, the steering lever 120 is pivoted further about the first pivot joint 121 until the over-center position is reached, which is described in the Fig. 4 and Fig. Figure 7 shows the second pivot joint 122 being located directly on the guide rail 111. Furthermore, the control rod 112 is pivoted towards the guide rail 111. The first end 113 of the control rod 112 is located close to the bottom of the guide rail 111.

[0052] The drive pin 116 can exit the drive cam 161 at the open end 162, so that the drive carriage 160 with the drive cam 161 can be moved further along the longitudinal direction X relative to the guide rail 111 and can also move without any movement being transmitted to the control rod 112 and / or the steering lever 120.

[0053] In the Fig. 4 and Fig. In the position shown in Figure 7, the steering lever 120 is arranged such that a force acting on the control rod 112 from the opening lever 130 cannot cause the steering lever 120 to pivot. This is referred to as the over-center position. Such forces occur during operation because the cover 130 is exposed to wind currents and other forces. These forces are largely transferred to the vehicle body 100 by means of the opening lever 130 and the guide rail 111. The over-center position of the steering lever 120 and the second pivot joint 122 ensures that the control rod 112 is held securely in the position in which the control rod 112 holds the opening lever 130 in the extended position. Thus, the opening lever 130 is reliably held in its extended position by means of the steering lever 120 and the control rod 121.The pivot joints, in particular the first pivot joint 121 and the second pivot joint 122, are arranged such that the guidance of the drive pin 116 in the drive cam 161 is necessary to return the steering lever 120 from the position according to . Fig. 4 and Fig. 7 to turn away.

[0054] To move the cover 103 into its closed position, the drive carriage 160 is moved relative to the guide rail 111 along the longitudinal direction X towards the front end 117. In doing so, the drive pin 116 engages in the drive cam 161 at the open end 162. The shape of the drive cam 161, in particular the inclined area, exerts a force on the drive pin 116, so that the steering lever 120 can be pivoted out of its over-center position and forward to the position shown. Fig. 2 and Fig. 5.

[0055] According to the exemplary embodiment, a retaining element 140 is provided on the guide rail. According to further exemplary embodiments, not explicitly shown, it is possible to omit the retaining element 140. The retaining element 140 is provided, for example, to additionally secure the control rod 112 and / or the steering lever 120 in the extended position of the extension lever 130.

[0056] In the illustrated embodiment, the retaining element 140 is designed as a spring. Both the second pivot joint 122 and a retaining pin 115 of the control rod 112 are positioned as shown. Fig. 4 and Fig. 7 engages with the retaining element 140. According to further embodiments not explicitly shown, it is possible that only the retaining pin 115 engages with the retaining element 140 and the second pivot joint 122 does not, or that only the second pivot joint 122 engages with the retaining element 140 and no additional retaining pin 115 is provided on the control rod.

[0057] The retaining pin 115 extends along the transverse direction Y over the control rod 112. The retaining pin 115 is located at the first end 113 of the control rod 112. The retaining pin 115 and the drive pin 116 extend along the transverse direction Y in opposite directions. The retaining pin 115 and the drive pin 116 are located on opposite sides of the control rod 112.

[0058] During the movement of the cover 103 into the open position, the second pivot joint 122 and the retaining pin 115 are pressed down onto the retaining element 140. The retaining element 140 is elastically designed and has a shape that exerts a force along the vertical direction Z on the retaining pin 115 and a force along the vertical direction Z on the second pivot joint 122. Thus, the control rod 112 and the steering lever 120 are additionally secured against unwanted deflection from the position according to Fig. 4 and Fig. 7 secured.

[0059] The pivot joints 102 to 106 of the joint mechanism, as well as the first pivot joint 121 and the second pivot joint 122 on the steering lever 120, are each designed as pure pivot joints with respective axes of rotation along the transverse direction Y. Translation of the respective two components connected to each other by means of the respective pivot joint 121, 122, 201 to 206, relative to each other, is blocked by the respective pivot joint. The control rod 112 can thus be reliably driven and, in particular, is reliably held in the open position of the cover 103 and fixed relative to the guide rail 111. The opening lever 130 is thus reliably held. The arrangement 110 has only pivot joints at the coupling of the steering lever 120 with the guide rail 111 and at the control rod 112 for coupling with the steering lever 120 to the opening lever 130 by means of the joint mechanism 200. Therefore, cam guides are unnecessary.Only the drive is implemented by means of the drive cam 161 and the drive pin 116.

[0060] Moving and locking the control rod 112 is achieved solely by means of the pivot joints. The first pivot joint 121 and the second pivot joint 122, together with the joint mechanism 200, form, for example, a purely two-dimensional seven-joint system. This makes it possible to transmit comparatively large forces to the extension lever 130. The steering lever 120 and the extension lever 130 are, for example, each mounted directly on the guide rail 111.

[0061] For example, from the Fig. 8 and Fig.As shown in Figure 9, the guide rail 111, according to exemplary embodiments, has a reinforcement 151 and a plastic guide 152. The plastic guide 152 at least partially surrounds the reinforcement 151. The reinforcement is designed and configured to stabilize the plastic guide 152. The reinforcement 151 is, for example, part of a frame that at least partially surrounds the roof opening 102. The frame serves, for example, to attach the assembly 110 to the vehicle body. It is also possible that the reinforcement 151 is designed as a reinforcing strip extending longitudinally along the longitudinal direction X. For example, the reinforcement 151 is made of a metal. The reinforcement 151 can also be referred to, for example, as a reinforcing plate.

[0062] The plastic guide 152, for example, contains or is made of polyurethane, preferably a thermoplastic. Examples of thermoplastics used include polyethylene terephthalate (PET), polyetheretherketone (PPEK), polyamides (PA), or partially aromatic polyamides (PPA).

[0063] The plastic guide 152, for example, has guide tracks and / or guide channels for the drive carriage 160 and / or other carriages and / or slides. Alternatively or additionally, a channel for a drive cable is formed in the plastic guide 152.

[0064] The plastic guide 152, for example, has a T-shaped cross-section perpendicular to the longitudinal axis X and features a guide area for the drive carriage 160 on opposite sides along the longitudinal axis, right and left. The drive carriage 160 is thus held and guided by the plastic guide 152.

[0065] The guide rail 111, due to its plastic construction, allows for a wide variety of shapes. Compared to conventional metal guide rails, the plastic guide rail also contributes to an improved CO2 balance and reduced noise generation when moving components in or on the guide rail.

[0066] In the illustrated embodiments, the joint mechanism 200 is attached to the reinforcement 151. In particular, the reinforcement 151 has a projection 153 that extends beyond the plastic guide 152. Specifically, no plastic guide 152 is formed on the projection 153. Specifically, two of the levers of the joint mechanism 200 are pivotably attached to the reinforcement 151. For example, joints 203 and 204 are formed on the reinforcement 151. Thus, for example, the release lever 130 is pivotably fixed to the reinforcement.

[0067] According to further embodiments not explicitly shown, the guide rail is designed as a conventional metal guide rail. The joint mechanism 200 is thus, for example, pivotably mounted directly to the metal guide rail. The metal guide rail is, for example, made of aluminum. The metal guide rail is, for example, U-shaped with respect to a cross-section perpendicular to the longitudinal axis X and has guide tracks and / or guide channels for the drive carriage 160 and / or other carriages and / or slides. The drive carriage 160 is thus, for example, held and guided by the metal guide rail.

[0068] The arrangement 100 enables a high force transmission, for example, when opening the cover 103 against wind load. The force is transmitted via the pivot joints 121, 122, 201 to 206. The arrangement of the first pivot joint 121 and the second pivot joint 122 enables self-locking of the steering lever 120 and thus of the control rod 112 due to the extended position, also known as the over-center position. The arrangement 110 therefore enables reliable operation.
