According to at least one embodiment, an arrangement for a vehicle roof with a roof opening is specified. The arrangement shows:

• - a cover that can be slid along a longitudinal direction for closing the roof opening,
• - a guide rail which is arranged on the vehicle roof,
• - a deployment lever which can be pivoted relative to the guide rail, the cover being displaceable in the longitudinal direction relative to the deployment lever in order to open the roof opening,
• - a drive carriage for pivoting the deployment lever, the drive carriage being guided in the guide rail so as to be displaceable along the longitudinal direction,
• - wherein the deployment lever has a first coupling to the guide rail and a second coupling to the guide rail,
• - wherein the first coupling and the second coupling are spaced apart from one another along the longitudinal direction and are designed such that the deployment lever can be displaced in sections relative to the guide rail along the longitudinal direction,
• - wherein the first coupling has a connecting link and a sliding pin, which is guided in the connecting link, and wherein the drive carriage is operatively connected to the opening lever at a region of the deployment lever assigned to the second coupling, in order to pivot and shift the deployment lever relative to the guide rail to drive

The arrangement is designed in particular for a so-called spoiler roof. In the case of spoiler roofs, the deployment lever is first rotated or pivoted on a rear edge in the opening direction in order to lift a rear edge of the cover. The cover is shifted in the opening direction relative to the deployment lever in order to at least partially release a roof opening. The deployment lever is held in place relative to the rest of the vehicle roof and is not pushed in the opening direction together with the cover. The further the cover is pushed backwards relative to the deployment lever, the greater the forces that have to be held by the deployment lever, and the greater the vibrations of the cover when the vehicle is in motion. Overcoming this is a long-held desire and can be improved with the solution described here.

This is different, for example, with so-called externally guided sunroofs, in which the deployment lever on the rear edge of the cover is shifted together with the cover in the opening direction relative to the rest of the vehicle roof. The problem described above does not occur there. However, such roofs cannot be used as a replacement for a spoiler roof, since they are completely different in design and the use of a spoiler roof or a roof that runs on the outside depends on the respective suitability of the vehicle base.

The deployment lever of the arrangement described here can be shifted in sections relative to the guide rail along the longitudinal direction. Apart from that, the raising lever can be locked relative to the guide rail so that it is not moved along with it when the cover is displaced relative to the guide rail along the longitudinal direction. Starting from a closed position of the cover, in which the cover closes the roof opening, the release lever is pivoted in order to raise the rear edge of the cover (so-called fan position). The arrangement described here subsequently enables the deployment lever to be displaced in the opening direction along a predetermined section before the deployment lever is locked relative to the guide rail and the cover is displaced further in the opening direction relative to the deployment lever. Compared to the prior art, this enables an improved support point for the cover on the opening lever and on the guide rail. Larger natural frequencies of the arrangement, in particular of the open cover, can be realized.

Lower bearing forces can be achieved at the end of the deployment lever on the guide rail side.

For this purpose, the deployment lever has the two spaced-apart couplings with the guide rail. A longer support ratio on the deployment lever can thus be achieved. This enables a larger opening width, i.e. a cover that is arranged comparatively far to the rear in the maximum opening position, compared to conventional spoiler mechanisms, in which the deployment lever is only arranged at a single pivot point on the guide rail and this pivot point cannot be displaced in the longitudinal direction.

The first coupling with the connecting link and the sliding pin enables the rotary movement and pivoting of the deployment lever. According to one embodiment, the connecting link is formed in the deployment lever and the slide pin is formed in a stationary manner on the guide rail. It is also possible for the slide pin to be formed on the deployment lever and for the slotted link to be formed in the guide rail. The first coupling enables a connection between the deployment lever and the guide rail that is of simple design and can therefore be implemented cost-effectively. In addition, it enables the comparatively long support ratio on the deployment lever and the longitudinal displaceability of the deployment lever relative to the guide rail.

The drive carriage is driven, for example, directly or indirectly by an electric motor of the arrangement. The drive carriage is arranged in the area of the deployment lever, ie in particular on a rear edge of the cover when the cover is in the closed position. The drive carriage is displaced along the longitudinal direction in order to pivot the deployment lever and to displace it along the longitudinal direction. After the pivoting movement and the displacement movement have been completed, the drive carriage, for example, is locked relative to the guide rail. To close the roof opening, the drive carriage is moved in the opposite direction, so that the deployment lever is pushed forward and swiveled back to close the cover.

Location information or direction information such as “rear” or “in front” is related to the longitudinal direction of the vehicle. The longitudinal direction of the vehicle can also be referred to as the horizontal direction or X-direction of a mathematical coordinate system. The cover would be raised or opened essentially in a vertical direction or Z-direction of the mathematical coordinate system. A rear area of the cover is to be understood, for example, as the area which, starting from a center of the cover, faces the rear of the vehicle.

According to at least one embodiment, the deployment lever has a shape that is always longer in the longitudinal direction than in the transverse and vertical directions in the operational state. The transverse direction and the vertical direction each run, for example, transversely to the longitudinal direction. In the folded-in state, when the cover is in its closed position, as well as in the ventilation position and in the open position of the cover, the drive carriage is therefore longer in the longitudinal direction than in particular in the vertical direction. This enables the favorable support ratio for the lid in the fan position and the open position. Regardless of the degree of pivoting, the deployment lever is always longer in the longitudinal direction than in the vertical direction.

According to at least one embodiment, the deployment lever has an area that is elongated in the longitudinal direction. The elongated area extends along the longitudinal direction, for example along at least 25% of the longitudinal extent of the lid in its closed position. The length of the elongate area is therefore, for example, at least 1/4 of the longitudinal extent of the lid. The length of the elongate area depends in particular on a desired support ratio for the cover in the ventilation position and/or the open position. It is also possible for the deployment lever to extend over 10% of the longitudinal extent of the lid, 20% of the longitudinal extent of the lid, 30% of the longitudinal extent of the lid or more, for example up to 50% of the longitudinal extent of the lid or more.

The longer the elongate area of the raising lever extends, the farther back an end of the raising lever on the cover side can be shifted. This enables the high natural frequencies and low bearing forces and a favorable support ratio. In its pivoted-out position, which is assigned to the fan position and/or the open position of the lid, the deployment lever is extended many times longer in the longitudinal direction than in the vertical direction, for example three times as long, five times as long, seven times as long or ten times as long long. Of course, other ratios of the longitudinally extended area along the longitudinal direction to the extension along the vertical direction are also possible.

According to at least one embodiment, the second coupling has a lifting link. The lifting link is designed to be stationary on the guide rail. The second coupling has a lift pin. The lift pin is on the off lever trained. The lifting pin is guided in the lifting link. When the deployment lever is displaced in the longitudinal direction, the lifting pin is moved along the lifting link. The lifting link has a shape such that a rear end of the deployment lever is raised and the deployment lever is thus pivoted. The shape of the lifting link also allows the deployment lever to be moved lengthwise.

According to at least one embodiment, the deployment lever has a drive link. The drive carriage has a drive pin. The drive pin is guided in the drive link in order to transfer a displacement of the drive carriage into a movement of the deployment lever. The drive link has a profile that allows the rear end of the deployment lever to be moved along the vertical direction and allows the deployment lever to be displaced along the longitudinal direction.

According to at least one embodiment, the lifting link and the drive link run in opposite directions to one another. The courses of the lifting link and the drive link intersect at least in the closed position of the cover. The drive link has a profile such that the drive link is initially further spaced from the guide rail along the opening direction and then approaches the guide rail as it progresses along the opening direction. For example, the drive link has areas that run essentially horizontally and inclined areas. So-called tolerance plateaus are thus possible, in which a displacement of the drive pin along the longitudinal direction does not cause any displacement or pivoting of the deployment lever.

The deployment backdrop has a profile such that the deployment backdrop initially runs inclined along the longitudinal direction and then runs essentially horizontally. Thus, beginning in the closed position, the deployment lever can first be pivoted and then the deployment lever can be displaced along the longitudinal direction until the lifting pin has reached the rear end of the lifting link.

In accordance with at least one embodiment, the deployment lever has a region which protrudes in the longitudinal direction and protrudes over a fixed roof element in the longitudinal direction when the cover is in the open position. In particular, the protruding portion protrudes rearward. The protruding portion is located behind the first and second couplings in the fan and open positions. In the closed position, the protruding portion is located in front of the fixed roof member along the longitudinal direction. Sliding the pop-out lever along the longitudinal direction relative to the guide rail enables the protruding portion to be positioned over the fixed roof element. This enables a high natural frequency and low bearing force on the deployment lever and a longer support ratio on the deployment lever. The lever force that is transferred from the cover to the raising lever is lower the further back the projecting area of the raising lever extends.

According to at least one embodiment, the arrangement has a further drive carriage. The cover has a front edge that faces away from the deployment lever in the closed position of the cover along the longitudinal direction. The lid has a lid slot on the front edge. For example, the cover has a cover carrier and the cover link is formed in the cover carrier. The additional drive carriage engages in the cover link in order to move the cover along the longitudinal direction. The additional drive carriage is connected directly to a drive cable, for example, which in turn transmits a driving force from an electric motor to the additional drive carriage.

The drive carriage and the further drive carriage are in particular temporarily connected to one another in such a way that the movement of the further drive carriage is transmitted to the drive carriage. This allows, for example, the pivoting and shifting of the deployment lever.

The further drive carriage and the drive carriage can be decoupled from one another, so that a movement of the further drive carriage is not transmitted to the drive carriage and thus to the deployment lever. The additional drive carriage can thus be displaced relative to the drive carriage and the opening lever, for example in order to move the cover between the ventilation position and the open position.

According to at least one embodiment, the arrangement has a lid slider. The lid slider is rigidly attached to the lid. For example, the lid has a lid support and the lid slider is rigidly attached to the lid support of the lid. In particular, the lid slider cannot be pivoted relative to the lid or is arranged on a lever which can be pivoted relative to the lid. This enables the front edge of the cover to be guided in a space-saving manner. The virtual axis of rotation of the lid between the closed position and the fan position can be arranged as far forward as possible. The virtual axis of rotation is the axis around which the lid actually pivots. This virtual axis of rotation can deviate from the mechanical axis of rotation on which the cover is pivotably held. This in turn makes it possible for the cover to be pushed back comparatively far along the opening direction, since the mechanism on the front edge of the cover requires little space and installation space.

According to at least one embodiment, a vehicle roof for a motor vehicle has an arrangement according to at least one of the embodiments described here. The vehicle roof has the movable cover. The cover and the roof opening are dimensioned in such a way that the roof opening can be closed at least along the opening direction to the rear at a rear edge of the cover by means of the cover alone. The roof opening is, for example, an opening in the fixed roof of the motor vehicle, which is formed from sheet metal. The roof opening is sized and the cover is sized to match each other such that the roof opening is closable by the movable cover by placing the rear edge of the cover directly adjacent to the fixed roof. In the ventilation position and the open position, the projecting area of the deployment lever is thus arranged above the fixed roof part of the vehicle roof, ie in particular above the tin roof and not above the roof opening.

According to further embodiments, a vehicle roof has the arrangement described here according to one of the described embodiments. The vehicle roof has the movable cover and another cover. The movable cover and the further cover as well as the roof opening are dimensioned, for example, in such a way that the cover and the further cover can be arranged together in the roof opening in the closed position. The movable cover and the further cover as well as the roof opening are dimensioned, for example, in such a way that the roof opening can be closed together by means of the cover and the further cover. The additional cover is arranged immovably in the roof opening relative to the rest of the vehicle roof, particularly in the operationally fixed state. In the closed position, the movable cover is arranged in front of the further cover in the roof opening and the two covers together close the roof opening. In the open position, the movable lid is arranged above the further lid. The additional cover thus continues to close part of the roof opening, in particular a rear part. In the open position, the protruding area of the deployment lever thus protrudes over the further cover.

1 shows a schematic representation of a vehicle roof 101 of a vehicle 100. The vehicle roof 101 is in particular part of the motor vehicle 100, in particular part of a passenger car. The vehicle roof 101 has a Arrangement 200 on. The arrangement 200 has a cover 103 . The cover 103 is used to close a roof opening 102. The roof opening can be closed and at least partially opened by moving the cover 103 along the longitudinal direction X. For this purpose, the cover 103 can be displaced along the X-direction relative to a fixed roof element 129 of the vehicle roof 101 .

1 shows the cover 103 in its closed position, in which the cover 103 closes the roof opening 102. Starting from the closed position, the cover 103 can be raised in the vertical direction Z and slid in the longitudinal direction X in order to at least partially expose the roof opening 102 .

The arrangement 200 is constructed in particular in the manner of a spoiler roof. As for example in 2 until 5 shown schematically, the arrangement 200 has a release lever 109 , also called the rear release lever 109 . The deployment lever 109 is used to raise and lower a rear edge 107 of the cover 103. The rear edge 107 is arranged along the longitudinal direction X of a front edge 106 of the cover 103 opposite. The front edge 106 of the cover 103 faces a windshield 104 of the vehicle 100 .

The raising lever 109 is supported on a guide rail 108 . The guide rail 108 is arranged along the longitudinal direction X and is connected to a body 105 of the vehicle 100 along a transverse direction Y next to the roof opening 102 . A guide rail 108 with an associated opening mechanism is arranged on each side of the roof opening 102 . The opening mechanism or the arrangement 200 is designed in the same way on both sides and corresponds to one another. In the following, only one side is described and what is described also applies correspondingly to the other side of the roof opening along the transverse direction Y.

The deployment lever 109 is supported on the guide rail 108 by means of a first coupling 111 and by means of a second coupling 112 . The first coupling 111 and the second coupling 112 are at a distance 113 from one another along the longitudinal direction X. The distance 113 is, for example, at least as large as about a quarter of the roof opening 112 along the longitudinal direction X, the distance 113 can also be larger or smaller. For example, the distance 113 is greater than 5 cm, in particular greater than 30 cm up to 50 cm or more or less.

A sliding pin 115 is formed on the guide rail 108 on the first coupling 111 . The sliding pin 115 extends along the transverse direction Y.

The first coupling 111 has a gate 114 which is formed in the release lever 109 . In particular, link 114 is formed on a first end 131 of deployment lever 109 . The first end 131 of the deployment lever 109 faces the windshield 104 . The connecting link 114 has an essentially rectilinear course which extends along the longitudinal direction X.

The sliding pin 115 is arranged in the link 114 . The deployment lever 109 is thus supported on the guide rail 108 by means of the connecting link 114 and by means of the sliding pin 115 . The support on the first coupling 111 is designed in such a way that the deployment lever 109 can be displaced along the longitudinal direction X. This is made possible by link 114 . In the closed position (e.g. compare also 8th and 9 ) of the cover, the sliding pin 115 is arranged on a rear end of the connecting link 114, that is to say one which faces away from the windshield 104. In the fan position and in particular in the open position of the cover, sliding pin 115 is arranged on a front end of link 114, i.e. on an end of link 114 facing windshield 104.

The second coupling 112 has a lifting link 122 . The lifting link 122 is arranged in a stationary manner in relation to the guide rail 108 and is part of the guide rail 108, for example.

A lifting pin 123 is guided in the lifting link 122 . The lifting pin 123 is formed on the release lever 109 (also compare 7 , 16 ). A course 126 of the lifting link 122 begins at the front end along the longitudinal direction X, ie the end facing the windshield 104, with a steeply rising area. Subsequently, the lifting link 122 has an essentially rectilinear area running along the longitudinal direction X. During its movement along the lifting link 122 starting in the closed position of the cover, the lifting pin 123 is consequently initially raised along the vertical direction Z and can subsequently be displaced along the longitudinal direction X without any further movement along the vertical direction Z. Accordingly, a rear end 132 of the deployment lever 109 is initially lifted essentially along the vertical direction Z and then shifted along the X direction.

The movement of the opening lever 109 is caused by a drive carriage 110 (ver same too 17 ). In the exemplary embodiment shown, the drive carriage 110 is coupled to another drive carriage 130 ( 3 ) driven. The additional drive carriage 130 is connected to an electric motor by means of a drive cable 139, for example a threaded cable that is resistant to tension and compression. During operation, the drive cable 139 displaces the further drive carriage 130 along the longitudinal direction X. This displacement is stopped starting in the closed position of the cover 103 by means of a locking device 135 ( 6 ) is transferred to the drive carriage 110. The drive carriage is thus also pushed backwards along the longitudinal direction X.

A drive pin 125 of drive slide 110 moves along a drive link 124 of deployment lever 109.

The drive link 124 has a course 127 which runs in the opposite direction to the course 126 of the lifting link 122 . At its front end, ie the end facing the windshield 104, the course 127 of the drive link 124 initially has a horizontal region running approximately along the longitudinal direction. This area essentially serves to compensate for tolerances, in which the drive pin 125 can move along the longitudinal direction X without causing the deployment lever 109 to move. The course 127 then falls away. If the drive pin 125 is arranged in this sloping area and the drive carriage 110 is pushed further to the rear, the raising lever 109 is lifted, since the lifting pin 123 is in the opposite, rising area of the lifting link 122 .

The path 127 of the drive link 124 has, in a central area, a further area which is aligned essentially in the horizontal direction and which is assigned, for example, to the position of the cover 103 in a fan position. Here, too, the course along the longitudinal direction X serves to compensate for tolerances. A sloping area is again provided in the drive link 124 in order to be able to move the deployment lever 109 backwards into its final position along the longitudinal direction X. If the deployment lever 109 is pivoted completely along the vertical direction Z and is displaced in the longitudinal direction X, the coupling between the drive carriage 110 and the further drive carriage 130 is released. The drive carriage 110 is locked relative to the guide rail 108 so that the drive carriage 110 and the deployment lever 109 are not moved any further when the other drive carriage 130 is moved further along the longitudinal direction X in order to push the cover 103 further backwards. To close the lid 103, the movement runs in the opposite direction. The additional drive carriage 130 can first be moved from the back to the front relative to the drive carriage 110. The locking device 135 then couples the two drive carriages 110, 130 to one another, so that the deployment lever 109 is pulled forward again and pivoted downwards.

The deployment lever 109 has a shape 117 . The shape 117 is significantly more extended in the longitudinal direction X than in the transverse direction Y and the vertical direction Z. The deployment lever 109 thus has a length 118 that is many times longer than a height 119 in the vertical direction Z. For example, the length 118 is many times greater than the height 119, even in the deployed position of the deployment lever 109, which is associated with the fan position or the open position of the cover 103. For example, the length 118 is twice as long as the height 119, three times as long, four times as long, five times as long or more up to ten times as long or more. A large distance 113 can thus be implemented.

Starting from a rear region 116, which is assigned to the second coupling 112 and which is arranged at the second end 132 of the deployment lever 109, the deployment lever 109 has an elongated region 120 that extends longitudinally forward in the direction of the windshield 4 is extended. In particular, this area also extends longitudinally forward along the longitudinal direction X when the deployment lever 109 is in the deployed position. In the closed position of the lid 103 and the venting position, the elongated portion 120 extends along a longitudinal extent 121 of the lid ( 1 ). The longitudinal extent of the lid extends between the front edge 106 and the rear edge 107 along the longitudinal direction X. From the rear end 132, the elongated region 120 extends, for example, along one fifth, one fifth, when the lid 103 is closed and the lid 103 is in the ventilation position A quarter, a third or more, for example up to half or up to two thirds of the longitudinal extension 121 of the cover 103 along the longitudinal direction X towards the front in the direction of the windshield 104.

The release lever 109 has a closing groove 142 in the rear area 116 . The locking groove 142 is open to the rear along the longitudinal direction X. The drive carriage 110 has a locking pin 143 . The locking pin 143 is arranged in the locking groove 142 when the cover 103 is in the closed position. The release lever 109 is pulled down along the vertical direction Z and held along the vertical direction Z by means of the closing pin 143 in order to close the cover 103 from the ventilation position. Thus is the lid 103 can be reliably closed and reliably held in the closed position even under strong forces.

The cover 103 has a cover support 140, for example. The cover has, for example, a flat panel, in particular a glass panel. The cover carrier 140 is arranged on the panel. The cover carrier 140 has a cover slider 134 at its front end facing the windshield 104 . The lid slide 134 is fixed rigidly and immovably to the lid support 140 and, in particular, cannot pivot relative to the lid support 140 . It is possible for the lid slider 134 to be rotatable relative to the lid support 140 about an axis of rotation running along the transverse direction Y. According to the exemplary embodiment, however, the lid slider 134 cannot move relative to the lid carrier 140 along the longitudinal direction X and/or the vertical direction Z. The lid slider 134 is guided in the guide rail 108 and is used to lift and move the front edge 106 of the lid 103.

A cover link 133 is formed on the cover carrier 140 in order to raise and lower the front edge 106 of the cover along the vertical direction Z. Starting at its front end facing the windshield 104 , the cover link 133 initially has an essentially rectilinear area running along the longitudinal direction X. A cover pin 144 of the additional drive carriage 130 is arranged in the cover link 133 . If the cover pin 144 shifts in the rectilinear area along the longitudinal direction X, this does not lead to a significant displacement of the front edge 106 along the longitudinal direction X. Only when the release lever 109 is deployed and the rear edge 107 is raised does the cover pin 144 reach for opening of the roof opening 102 a sloping area of the cover link 133. When the cover pin 144 is arranged in the sloping area of the cover link 133, the displacement movement of the further drive carriage 130 is transmitted to the cover carrier 140 and the cover 103 is displaced along the longitudinal direction X.

The locking device 135 is implemented as a locking element 138, for example by means of a drive cable that is resistant to tension and compression. The locking element 138 is firmly connected to the drive carriage 110 and extends forward along the longitudinal direction X. The locking element 138 can be selectively connected to the additional drive carriage 130 by means of a locking pin 136 or can be detached from the additional drive carriage 130 and locked to the guide rail 108 along the longitudinal direction X. The locking element 138 is guided, for example, in a locking link 137 of the guide rail 108 . In order to be decoupled from the further drive carriage 130 and to be locked with the guide rail 108 along the longitudinal direction X, the locking pin 136 is rotated about an axis of rotation, for example, which corresponds to the longitudinal direction X. In a state in which the locking pin 136 is connected to the further drive carriage 130, the locking pin 136 is aligned along the transverse direction Y. In a state in which the locking pin 136 is locked to the guide rail 108, the locking pin 136 is aligned along the vertical Z direction.

Other exemplary embodiments of the locking device 135 are also possible. For example, the locking element 138 is designed as a rigid locking lever, as a resilient, flexible locking element 138 or in some other way. The locking element 138 and the locking device 135 are designed such that a movement of the further drive carriage 130 can be temporarily transferred to the drive carriage 110 and the drive carriage 110 can be immovably locked with the guide rail in other states relative to the guide rail 108 .

10 until 12 show the arrangement 200 with the deployment lever 109 at least partially deployed. The rear end 132 of the deployment lever 109 has been raised along the vertical direction Z compared to the closed position of the cover 103 . For this purpose, the drive carriage 110 has been displaced along the longitudinal direction X and the drive pin 125 has been displaced in the drive link 124 . However, the lifting pin 123 is still arranged in the steeply rising area of the lifting link 122 . The deployment lever 109 has not yet shifted significantly along the longitudinal direction X. Only the rear edge 107 of the lid 103 has been raised. Also, the front edge 106 of the lid 103 has not been moved significantly. The lid slider 134, which is located outwardly along the Y-direction on the lid support 140, has not been moved significantly. The connecting link 114 has not yet been significantly displaced relative to the slide pin 115 .

13 until 15 show the arrangement 200 in the open position of the cover 103. In comparison to the fan position according to FIG 10 until 12 the drive carriage 110 has been pushed further backwards along the longitudinal direction X until the lifting pin 123 is arranged at the end of the lifting link 122 . Accordingly, the drive pin 125 has been shifted to the rear end of the drive link 124 . The deployment lever 109 has consequently been raised to its maximum deployed position and has also been pushed backwards in the longitudinal direction X. For this purpose, link 114 has also been shifted relative to sliding pin 115 .

The deployment lever 119 is reliably supported on the two spaced-apart decouplings 111, 112 both in the illustrated open position of the cover 103 and in the fan position and the closed position of the cover 103. Reliable support of the forces that are introduced into the arrangement 200 via the opened cover 103 is thus possible, particularly in the open position, on the guide rail 108 and thus on the body 105 . Thus, the cover 103 can be pushed back comparatively far.

In the fully open position, the connecting link 114 of the deployment lever is arranged in front of the cover pin 144 along the longitudinal direction X. In the fully open position, the additional drive carriage 130 is arranged behind the connecting link 114 . The additional drive slide 130 and the cover pin 144 are arranged in the fully open position along the longitudinal direction X between the two ends 131, 132 of the deployment lever 109. The further drive carriage 130 and the cover pin 144 are arranged in the fully open position between the slide pin 115 and the lifting pin 123 . In the fully open position, the longitudinally extended area 120 of the deployment carriage 109 extends along the longitudinal direction X from back to front past the further drive carriage 130 . The further drive carriage 130 is arranged in the fully open position along the transverse direction Y next to the release lever 109 .

In particular, it is also possible to embody the deployment lever 109 with a region 128 projecting to the rear. This rearwardly projecting area 128 jumps over the rear fixed roof element 129 in the open position of the cover. It is thus possible to support the cover carrier 140 comparatively at the rear and in particular above the fixed roof element 129 . Supporting the cover carrier 140 as far to the rear as possible along the longitudinal direction X reduces the leverage forces which are applied to the two couplings 111 , 112 via the cover carrier 140 . A displacement companion 141, which is arranged at the rear end 132 of the deployment lever 109 and in which the cover carrier 140 is slidably mounted, is arranged above the fixed roof element 129 when the cover 103 is open.

The fixed roof element 129 is, for example, another cover that is arranged in the roof opening 102 . It is also possible for the fixed roof element 129 to be part of the vehicle body or a panel forming the vehicle roof 101 and surrounding the roof opening 102 . The arrangement 200 is constructed in such a way that the elements of the arrangement 200 and other mechanical elements do not have to get under the fixed roof element 129 in order to open the cover 103 completely. In particular, the additional drive carriage 130 is only moved up to approximately the area of the lifting link 122 . The movement of the cover carrier 140 by means of the cover link 133, which is arranged very far forward on the cover carrier 140, nevertheless enables the cover carrier 140 to be moved far to the rear and the roof opening 102 to be opened up to a large extent.

18 shows a schematic representation of the forces and lever ratios at the support points A and B of the cover when the cover 103 is open. The further back the front support point A, i.e. in particular the cover slider 134, is arranged, the further the roof opening 102 can be released. However, a minimum distance i between support points A and B is necessary in order to be able to hold cover 103 reliably. There are also acting leverage forces, since the distance 1 between the front support point A and the rear edge 107 of the cover 103 is significantly longer than the distance k between the front support point A and the displacement companion 141 on which the cover 103 is supported. Leverage forces result from the difference between 1 and k, which become smaller the further back the displacement companion 141 can be arranged. The protruding portion 128 thus allows leverage forces to be reduced since the ratio of k to 1 improves compared to a deployment lever that does not protrude rearwardly. Reducing the lever forces in turn makes it possible to reduce the minimum distance i, since fewer forces act overall and the cover 103 can therefore be held reliably even when i is smaller. In order to reduce the minimum distance i, the elongated deployment lever 109 is also provided, which enables the cover 103 to be supported in front of the support point A, which is also explained below with reference to FIG 19 is explained in more detail.

19 shows a schematic representation of the forces and lever ratios on the couplings 111, 112 when the cover 103 is open. The displacement companion 141 is arranged in its rearmost position along the longitudinal direction X and positioned above the fixed roof element 129. A lever which results from the distance f between the two points C and B therefore acts on the front coupling 111 of the deployment lever 109 . B is the point of application of the forces on displacement companion 141 and C is the point of application of the forces on sliding pin 115 and link 114. The forces to be introduced are also determined by the distance 113 or e between points C and D. D corresponds to the point of application of the forces on the second coupling 112 on the lifting link 122 and the lifting pin 123.

Point B is offset rearwardly with respect to point D because the projecting portion 128 projects rearwardly. The further point B is shifted to the rear, the lower the forces introduced by the opened cover 102 on the lever 103, since the lever forces that occur due to the ratio 1 to k ( 18 ). The leverage of the lid area located behind point B thus becomes less. For example, when the lid 103 is fully opened, a ratio of the distance between the lid slider 134 and the shifting companion 141 to the length of the lid 103 between the lid slider 134 and the rear edge 107 is greater than 0.25, in particular greater than 0.28 or greater than 0.3 . Other conditions are also possible, in which the force acting on the displacement companion 141 is as small as possible. For example, a support ratio e:f is as large as possible in order to keep the force acting on the second coupling 112 as low as possible.

The forces to be held by the deployment lever 109 are determined in particular by the ratio f:e. The lower the ratio f:e, the more evenly the forces to be absorbed by the deployment lever 109 are distributed to the points of application C and D. The closer the ratio f:e is to the value 1.0, for example, the more evenly the forces to be absorbed by the deployment lever 109 are distributed over the points of application C and D. With the length of the projecting area 128 remaining the same, the forces to be absorbed at point D become smaller the further forward the first coupling 111 is arranged. The forces to be absorbed at point D decrease the larger the distance 113 or e between points C and D is, with the same distance along the longitudinal direction X between points D and B.

The forces to be absorbed at points A and D can therefore be reduced both by shifting the point of application B on the displacement companion 141 to the rear by means of the projecting area 128, and by arranging the first coupling 111 comparatively far forward by means of the elongated area 120 of the release lever 109.

The realization of both the first coupling 111 and the second coupling 112 by means of links 114 or 122 and 124 enables a flexible design of the individual lengths and expansions based on the desired opening widths and achievable force ratios.

The support ratio on the deployment lever 109 can be adjusted so reliably that a wide opening width can be achieved. The support point B on the displacement companion 141 for supporting the cover carrier 140 is moved to the rear. The deployment lever 109 is mounted at two support points on the first coupling 111 and on the second coupling 112 . The front support point of the first coupling 111 is supported by the link 114 in the deployment lever 109 and on the sliding point 115 fastened to the guide rail 108 . A rotational movement of the deployment lever 109 can thus be effected via a usefully selected link guide, which provides an additional stroke on the displacement companion 141 and promotes a comparatively large support ratio of the deployment lever 109 .

The supporting conditions acting on the cover support 140 and on the opening lever 109 due to the positions B and C with a constant position D in the longitudinal direction can be coordinated with one another even with comparatively large opening widths in such a way that the greatest supporting force acting at the point of application D is, for example, equivalent to conventional mechanisms which the deployment lever is aligned perpendicularly to the vertical direction Z when the roof is open and, in particular, does not protrude backwards beyond the fixed roof element 129. For example, a force that is less than 10% greater than the force acting on point B on displacement companion 141 acts at point D, for example between 6% and 9% greater. Of course, other balances of power are also possible. For example, the length f is approximately 440 millimeters and the length e is approximately 400 millimeters. For example, a difference between the lengths e and f is greater than 10 millimeters and less than 50 millimeters.

The deployment lever 109 is driven by means of the drive slide 110 and by means of the locking device 135 to the further drive slide 130 . For this purpose, the drive pin 125 is formed in the drive carriage 110 and moves in the drive link 124 in the deployment lever 109 . The drive link 124 is designed as a cross link for the lifting link 122 . In addition, the drive link 124 has the tolerance-compensating plateaus for the closed position and for the fan position. Furthermore, it is possible to realize any transmission ratios by means of the drive link 124 . The coupling or locking between the drive carriage 110 and the further drive carriage 130 or the guide rail 108 takes place, for example, by means of the locking pin 136 rotatable about the longitudinal axis or other locking devices.

The mechanism on the front edge 106 of the cover 103 makes it possible to avoid a second control link in the cover support 140. Only a single slide 134 is used on the cover support 140, which is positioned far in front on the cover 103. in particular as close as possible to the virtual axis of rotation of the cover 103. A large opening width along the longitudinal direction X is thus possible. In addition, the space-saving locking device 135 enables a large opening width of the roof opening 102 and a low-noise and smooth locking process. The number of components can be reduced compared to other conventional mechanisms. The complexity is thus reduced and the arrangement 200 can be implemented in a cost-efficient manner. Overall, high natural frequencies can be realized when the cover 103 is open. In the rear support point on the second coupling 112 of the release lever 109, lower bearing forces can be realized due to the longer support ratio on the release lever 109.

It is also possible to realize the vehicle roof 104 with only a single cover for closing the roof opening 102, namely the movable cover 103, since no mechanical components have to be pushed backwards under the fixed roof 129.

The realization by means of the links 114, 122 and 124 allows a great deal of design freedom and sufficient tolerances. Overall, the arrangement 200 can be implemented with a comparatively small number of components. The arrangement 200 enables a reliable opening and closing of the roof opening 102.
