Description

Technical Field

[0001] This invention proposes a device for the roof of a motor vehicle, particularly a device for the movement of a movable cover used to close a roof opening. Furthermore, it proposes a device for the roof of a motor vehicle, particularly a roof having the device described herein. Background Technology

[0002] A device with a movable cover for the roof can be implemented as a so-called spoiler roof, as described, for example, in document DE 102012 106 545A1.

[0003] It is desirable to propose a device for vehicle roofs that enables reliable operation. Furthermore, it is desirable to propose a vehicle roof that enables reliable operation. Summary of the Invention

[0004] According to at least one embodiment, a device for a vehicle roof with a roof opening is provided. The device has:

[0005] - A cover that is movable along the longitudinal direction for closing the roof opening;

[0006] -Guide rails, which are installed on the roof of the vehicle;

[0007] - An unfolding lever, which is deflectable relative to a guide rail, wherein the cover is movable relative to the unfolding lever in the longitudinal direction in order to open the roof opening;

[0008] - A drive slider for deflecting the unfolding lever, wherein the drive slider is movably guided in a guide rail along the longitudinal direction;

[0009] -The deploying lever has a first coupling element coupled to the guide rail and a second coupling element coupled to the guide rail;

[0010] -The first coupling member and the second coupling member are spaced apart from each other along the longitudinal direction and are constructed such that the unfolding lever section is movable relative to the guide rail along the longitudinal direction;

[0011] -The first coupling member has a groove and a sliding pin, the sliding pin being guided in the groove and driving the slider to be effectively connected to the unfolding lever in the area of ​​the unfolding lever configured for the second coupling member, so as to drive the unfolding lever to deflect and move relative to the guide rail.

[0012] This device is specifically configured for so-called spoiler roofs. In the case of a spoiler roof, a deploying lever is first rotated or deflected at the rear edge along the opening direction to raise the rear edge of the cover. The cover moves relative to the deploying lever in the opening direction to at least partially open the roof opening. Here, the deploying lever is fixed relative to the rest of the roof and does not move with the cover in the opening direction. The further the cover moves rearward relative to the deploying lever, the greater the force that must be maintained by the deploying lever, and the greater the vibration of the cover when the vehicle is in motion. Overcoming this is a long-standing expectation and can be improved using the solution described herein.

[0013] This differs from, for example, the case of a so-called externally guided sliding roof, where the deployment lever moves along with the roof at the rear edge of the cover in the opening direction relative to the rest of the roof. The aforementioned problem does not occur here. However, such a roof cannot be used as a substitute for a spoiler roof because they are fundamentally different in construction, and the application of a spoiler roof or an externally guided roof is related to the corresponding capabilities of the vehicle base.

[0014] The device described herein features an unfolding lever that can move segmentally relative to a guide rail in the longitudinal direction. Furthermore, the unfolding lever is lockable relative to the guide rail so that the cover is not carried along during longitudinal movement relative to the guide rail. From the closed position of the cover (where the cover closes the roof opening), the unfolding lever deflects to raise the rear edge of the cover (the so-called ventilated position). Before the unfolding lever is locked relative to the guide rail and the cover continues to move relative to the unfolding lever in the opening direction, the device described herein allows the unfolding lever to move along a predetermined segment in the opening direction. This provides improved support points for the cover on the unfolding lever and on the guide rail compared to existing technologies. A larger natural frequency of the opened cover is achievable with this device.

[0015] Lower support force can be achieved at the end of the guide rail side of the unfolding lever.

[0016] The deploying lever has two spaced-apart coupling devices coupled to the guide rail. This allows for a longer support ratio on the deploying lever. Compared to traditional spoiler mechanisms (where the deploying lever is positioned on the guide rail at only one single point of rotation and cannot move longitudinally), this enables a larger opening width, i.e., a cover positioned relatively far back in the maximum open position.

[0017] A first coupling member with a groove and a sliding pin enables the rotational movement and deflection of the deploying lever. In one embodiment, the groove is constructed within the deploying lever, and the sliding pin is fixedly positioned on the guide rail. Alternatively, the sliding pin may be constructed on the deploying lever, while the groove is constructed within the guide rail. The first coupling member enables a connection between the deploying lever and the guide rail, a connection that is simply designed and therefore cost-effective. Furthermore, the first coupling member enables a relatively long support ratio on the deploying lever and longitudinal mobility of the deploying lever relative to the guide rail.

[0018] The drive slider is driven, for example, indirectly or directly, by the motor of the device. The drive slider is located in the area of ​​the unfolding lever, specifically on the rear edge of the cover in the closed position. The drive slider moves longitudinally to deflect the unfolding lever and move it longitudinally. After the deflection and movement are completed, the drive slider is locked relative to a guide rail, for example. To close the roof opening, the drive slider moves in the opposite direction, causing the unfolding lever to move forward and deflect back to close the cover.

[0019] The positional or directional designations used, such as "rear" or "front," refer to the vehicle's longitudinal direction. The vehicle's longitudinal direction can also be referred to as the horizontal direction or X-direction of the mathematical coordinate system. The lifting or unfolding of the cover is essentially achieved along the vertical direction or Z-direction of this mathematical coordinate system. The rear region of the cover can be understood, for example, as the region extending from the center of the cover towards the rear of the vehicle.

[0020] According to at least one embodiment, the deploying lever has a shape such that, in the ready state, it is always longer along the longitudinal direction than along the transverse and vertical directions. The transverse and vertical directions, for example, each extend laterally than the longitudinal direction. That is, not only in the closed state (when the cover is in its closed position) but also in the ventilated position and in the open position of the cover, the drive slider is configured to be longer along the longitudinal direction than, particularly, along the vertical direction. This achieves an advantageous support ratio for the cover in the ventilated and open positions. Regardless of the degree of deflection, the deploying lever is always longer along the longitudinal direction than, particularly, along the vertical direction.

[0021] According to at least one embodiment, the deploying lever has an elongated region extending longitudinally. This elongated region extends longitudinally, for example, at least 25% of the longitudinal extension of the cover in its closed position. That is, the length of the elongated region is, for example, at least one-quarter of the longitudinal extension of the cover. The length of the elongated region is particularly related to the desired proportion of support for the cover in the ventilated and / or open position. It is also possible that the deploying lever extends beyond 10%, 20%, 30%, or more of the longitudinal extension of the cover, for example, up to 50% or more of the longitudinal extension of the cover.

[0022] The longer the elongated extension area of ​​the unfolding lever extends, the further the end of the unfolding lever on the cover side can be moved. This allows for a large natural frequency, low support force, and a favorable support ratio. In the deflected position of the unfolding lever (configured for the ventilated and / or open position of the cover), the unfolding lever extends many times longer in the longitudinal direction than in the vertical direction, for example, three, five, seven, or ten times. Of course, other ratios of the elongated extension area in the longitudinal direction to the vertical extension are also possible.

[0023] According to at least one embodiment, the second coupling member has a lifting groove. This lifting groove is fixedly mounted on a guide rail. The second coupling member has a lifting pin. This lifting pin is mounted on the deploying lever. The lifting pin is guided within the lifting groove. When the deploying lever moves longitudinally, the lifting pin moves along the lifting groove. The lifting groove has a shape that raises the rear end of the deploying lever, thus deflecting the deploying lever. The shape of the lifting groove also allows for longitudinal movement of the deploying lever.

[0024] According to at least one embodiment, the deploying lever has a drive groove. The drive slider has a drive pin. The drive pin is guided in the drive groove to convert the movement of the drive slider into the movement of the deploying lever. The drive groove has a orientation that enables the rear end of the deploying lever to move vertically and also enables the deploying lever to move longitudinally.

[0025] In at least one embodiment, the lifting slide and the drive slide have opposite orientations. The orientations of the lifting slide and the drive slide intersect at least in the closed position of the cover. The drive slide has an orientation such that it first moves away from the guide rail in the opening direction and then approaches the guide rail in a further orientation in the opening direction. For example, the drive slide has a substantially horizontally extending region and an inclined region. Thus, a so-called tolerance boss can be implemented, in which the longitudinal movement of the drive pin does not cause movement or deflection of the unfolding lever.

[0026] The adjusting slide has a direction such that it first extends obliquely in the longitudinal direction and then extends substantially horizontally. Therefore, in the closed position, the deploying lever can be deflected first and then moved in the longitudinal direction until the lifting pin reaches the rear end of the lifting slide.

[0027] According to at least one embodiment, the deploying lever has a longitudinally projecting region that protrudes longitudinally from the fixed roof member in the open position of the cover. This projecting region specifically protrudes rearward. In the ventilated and open positions, the projecting region is positioned after the first and second coupling members. In the closed position, the projecting region is positioned longitudinally in front of the fixed roof member. Movement of the deploying lever relative to the guide rails in the longitudinal direction makes it possible for the projecting region to be positioned above the fixed roof member. This allows for a large natural frequency, low support force on the deploying lever, and a longer support ratio on the deploying lever. The further the projecting region of the deploying lever extends rearward, the smaller the leverage force transmitted from the cover to the deploying lever.

[0028] In at least one embodiment, the device has another drive slider. The cover has a front edge that faces away from the unfolding lever in the longitudinal direction when the cover is in the closed position. The cover has a cover groove on the front edge. For example, the cover has a cover support and the cover groove is formed in the cover support. The other drive slider engages with the cover groove to move the cover in the longitudinal direction. The other drive slider is, for example, directly connected to a drive cable that transmits the driving force of the motor to the other drive slider.

[0029] The drive slider and the other drive slider are temporarily connected to each other such that the movement of the other drive slider is transmitted to the drive slider. This, for example, enables the deflection and movement of the unfolding lever.

[0030] The other drive slider is decoupled from the first drive slider, so that the movement of the other drive slider is not transmitted to the first drive slider and thus to the unfolding lever. Therefore, the other drive slider is movable relative to the first drive slider and the unfolding lever, for example, to move the cover between a ventilated position and an open position.

[0031] According to at least one embodiment, the device has a cover slider. The cover slider is rigidly fixed to the cover. For example, the cover has a cover support and the cover slider is rigidly fixed to the cover support. The cover slider is particularly configured to be non-deflectable relative to the cover or positioned on a lever that can be deflected relative to the cover. This enables space-saving guidance of the front edge of the cover. The virtual axis of rotation of the cover between the closed and ventilated positions can be positioned as far forward as possible. This virtual axis of rotation is an axis around which the cover actually deflects. This virtual axis of rotation can differ from a mechanical axis of rotation in which the cover is rotatably held. This, in turn, allows the cover to move relatively far backward in the opening direction because the mechanical device on the front edge of the cover requires minimal positional and structural space.

[0032] According to at least one embodiment, the roof of a motor vehicle has a device according to at least one of the embodiments described herein. The roof has a movable cover. The cover and the roof opening are designed and sized such that the roof opening is closable solely by means of the cover, at least rearward along the opening direction, on the rear edge of the cover. The roof opening is, for example, an opening in the fixed roof of a motor vehicle, the fixed roof being formed of a sheet metal. The roof opening has a size and the cover has a size, they are coordinated such that the roof opening is closable by means of the movable cover, in which the rear edge of the cover is directly adjacent to the fixed roof. Therefore, in the ventilated position and the open position, the protruding area of ​​the unfolding lever is located above the fixed roof member of the roof, that is, particularly above the sheet metal roof and not above the roof opening.

[0033] According to another embodiment, the roof has a device described herein as in one of the embodiments described herein. The roof has a movable cover and another cover. The movable cover, the other cover, and the roof opening are sized such that the cover and the other cover can be jointly positioned within the roof opening in the closed position. The movable cover, the other cover, and the roof opening are sized such that the roof opening can be closed by means of the cover and the other cover. The other cover is immovably positioned within the roof opening relative to the rest of the roof, particularly in the ready state. In the closed position, the movable cover is positioned in the roof opening before the other cover, and both covers jointly close the roof opening. In the open position, the movable cover is positioned above the other cover. Therefore, the other cover still closes a portion of the roof opening, particularly the rear portion. Therefore, in the open position, the protruding area of ​​the unfolding lever protrudes from the other cover. Attached Figure Description

[0049] Figure 1 A schematic diagram of the roof 101 of a vehicle 100 is shown. The roof 101 is particularly a part of the vehicle 100, particularly a part of a sedan. The roof 101 has a device 200. The device 200 has a cover 103. The cover 103 is used to close the roof opening 102. The roof opening is closable and at least partially openable by means of movement of the cover 103 in the longitudinal direction X. For this purpose, the cover 103 is movable in the X direction relative to the fixed roof member 129 of the roof 101.

[0050] Figure 1 The cover 103 is shown in its closed position, in which the cover 103 closes the roof opening 102. From the closed position, the cover 103 is liftable in the vertical direction Z and movable in the longitudinal direction X so as to at least partially open the roof opening 102.

[0051] Device 200 is specifically configured in a manner consistent with a spoiler roof. For example, in... Figures 2 to 5As schematically shown, the device 200 has an unfolding lever 109, also referred to as a rear unfolding lever 109. The unfolding lever 109 is used to raise and lower the rear edge 107 of the cover 103. The rear edge 107 is disposed opposite the front edge 106 of the cover 103 along the longitudinal direction X. The front edge 106 of the cover 103 faces the windshield 104 of the vehicle 100.

[0052] The lever 109 is supported on the guide rail 108. The guide rail 108 is arranged along the longitudinal direction X and connected to the body 105 of the vehicle 100 next to the roof opening 102 in the transverse direction Y. Guide rails 108 are provided on both sides of the roof opening 102, each with its own adjustment mechanism. The adjustment mechanism or device 200 is configured similarly or correspondingly on both sides. Only one side is described below; this description also applies to the other side of the roof opening in the transverse direction Y.

[0053] The lever 109 is supported on the guide rail 108 by means of a first coupling member 111 and a second coupling member 112. The first coupling member 111 and the second coupling member 112 are spaced 113 apart from each other along the longitudinal direction X. This space 113 is, for example, at least about one-quarter of the length of the roof opening 112 along the longitudinal direction X, and can be larger or smaller. For example, the space 113 is greater than 5 cm, particularly greater than 30 cm to 50 cm, or larger or smaller.

[0054] At the first coupling member 111, a sliding pin 115 is formed on the guide rail 108. The sliding pin 115 extends along the lateral direction Y.

[0055] The first coupling member 111 has a groove 114 constructed in the deploying lever 109. In particular, the groove 114 is constructed on the first end 131 of the deploying lever 109. The first end 131 of the deploying lever 109 faces the windshield 104. The groove 114 has a substantially straight orientation that extends along the longitudinal direction X.

[0056] A sliding pin 115 is disposed in the groove 114. Therefore, the unfolding lever 109 is supported on the guide rail 108 by means of the groove 114 and the sliding pin 115. The support on the first coupling member 111 is designed such that the unfolding lever 109 is movable along the longitudinal direction X. This is achieved by the groove 114. In the closed position of the cover (see also...), Figure 8 and 9 The sliding pin 115 is provided at the rear end of the slide groove 114, that is, the end facing away from the windshield 104. In the ventilated position of the cover, and especially in the open position, the sliding pin 115 is provided at the front end of the slide groove 114, that is, the end of the slide groove 114 facing the windshield 104.

[0057] The second coupling member 112 has a lifting slide 122. The lifting slide 122 is fixedly positioned relative to the guide rail 108 and is, for example, part of the guide rail 108. Alternatively, the lifting slide 122 may be constructed in a separate component and the component may be fixedly connected to the guide rail 108.

[0058] The lifting pin 123 is guided in the lifting slide 122. The lifting pin 123 is constructed on the unfolding lever 109 (see also...). Figure 7 , Figure 16 The direction 126 of the lift slide 122 begins with a steep rise at its front end along the longitudinal direction X, i.e., at the end facing the windshield 104. Then, the lift slide 122 has a substantially straight region extending along the longitudinal direction X. Therefore, along its movement along the lift slide 122 starting in the closed position of the cover, the lift pin 123 first rises along the vertical direction Z and then moves along the longitudinal direction X without further movement along the vertical direction Z. Correspondingly, the rear end 132 of the unfolding lever 109 also first rises substantially along the vertical direction Z and then moves along the X direction.

[0059] The movement of lever 109 is caused by driving slider 110 (see also) Figure 17 In the illustrated embodiment, the drive slider 110 is driven by means of another drive slider 130 (…). Figure 3 The coupling of the two drives is driven. The other drive slider 130 is connected to the motor by means of a drive cable 139, such as a tensile and compressive threaded cable. The drive cable 139 moves the other drive slider 130 along the longitudinal direction X during operation. This movement begins in the closed position of the cover 103 by means of the locking device 135. Figure 6 This is transmitted to the drive slider 110. That is, the drive slider also moves backward along the longitudinal direction X.

[0060] Here, the drive pin 125 of the drive slider 110 moves along the drive groove 124 of the unfolding lever 109.

[0061] The drive slide 124 has a direction 127 that is opposite to the direction 126 of the lift slide 122. At its front end, i.e., the end facing the windshield 104, the direction 127 of the drive slide 124 first has a horizontal region extending generally in the longitudinal direction. This region essentially serves as tolerance compensation, in which the drive pin 125 can move in the longitudinal direction X without causing movement of the deploying lever 109. Then, the direction 127 descends. If the drive pin 125 is positioned in this descending region and the drive slider 110 continues to move rearward, then the deploying lever 109 rises because the lift pin 123 is located in the opposite rising region of the lift slide 122.

[0062] The drive slide 124 has a generally horizontally oriented region in its intermediate area, which is configured, for example, for the position of the cover 103 in the ventilated position. Furthermore, the orientation along the longitudinal direction X serves as tolerance compensation. Next, a descending region is provided in the drive slide 124 to allow the unfolding lever 109 to move rearward along the longitudinal direction X to its final position. If the unfolding lever 109 deflects completely along the vertical direction Z and moves along the longitudinal direction X, the coupling between the drive slider 110 and the other drive slider 130 is released. If the other drive slider 130 continues to move along the longitudinal direction X to allow the cover 103 to continue moving rearward, the drive slider 110 is locked relative to the guide rail 108, thereby preventing further movement of the drive slider 110 and the unfolding lever 109. To close the cover 103, the movement is reversed. First, the other drive slider 130 can be moved from rear to front relative to the drive slider 110. Subsequently, the locking device 135 couples the two drive sliders 110, 130 together, thereby pulling forward and deflecting downward the unfolding lever 109.

[0063] The unfolding lever 109 has a shape 117. This shape 117 extends significantly more along the longitudinal direction X than along the transverse direction Y and the vertical direction Z. Therefore, the unfolding lever 109 has a length 118, which is many times longer than the height 119 along the vertical direction Z. For example, this length 118 is also many times greater than the height 119 in the unfolded position of the unfolding lever 109—the unfolded position configured for the ventilation or open position of the cover 103. For example, the length 118 is two, three, four, five, or even more than ten times the height 119. This allows for a large gap 113.

[0064] Starting from the rear region 116 (which is configured for the second coupling member 112 and is located on the second end 132 of the deployment lever 109), the deployment lever 109 has an elongated extended region 120 that extends elongatedly forward toward the windshield 4 in the longitudinal direction X. This region also extends elongatedly in the longitudinal direction X in the deployed position of the deployment lever 109. In the closed and ventilated positions of the cover 103, the elongated extended region 120 extends along the longitudinal extension 121 of the cover. Figure 1 The longitudinal extension of the cover extends along the longitudinal direction X between the front edge 106 and the rear edge 107. Starting from the rear end 132, the elongated extended region 120 extends forward along the longitudinal direction X toward the windshield 104, for example, one-fifth, one-quarter, one-third or more, up to one-half or up to two-thirds of the longitudinal extension 121 of the cover 103, when the cover 103 is closed and when the cover 103 is in a ventilated position.

[0065] The unfolding lever 109 has a closing groove 142 in the rear region 116. This closing groove 142 opens rearward along the longitudinal direction X. The drive slider 110 has a closing pin 143. This closing pin 143 is positioned in the closing groove 142 in the closed position of the cover 103. To close the cover 103 from the ventilated position, the unfolding lever 109 is pulled downward along the vertical direction Z by means of the closing pin 143 and held in the vertical direction Z. Therefore, the cover 103 can be reliably closed and reliably held in the closed position even under strong forces.

[0066] The cover 103, for example, has a cover support 140. The cover has, for example, a planar panel, particularly a glass panel. The cover support 140 is provided on this panel. The cover support 140 has a cover slider 134 at its front end, i.e., the end facing the windshield 104. The cover slider 134 is rigidly and immovably fixed to the cover support 140 and, in particular, cannot be deflected relative to the cover support 140. It is possible that the cover slider 134 is rotatable relative to the cover support 140 about a rotation axis (which extends in the transverse direction Y). However, according to an embodiment, the cover slider 134 is immovable relative to the cover support 140 along the longitudinal direction X and / or the vertical direction Z. The cover slider 134 is guided in a guide rail 108 and is used to lift and move the front edge 106 of the cover 103.

[0067] A cover groove 133 is formed on the cover bracket 140 to raise and lower the front edge 106 of the cover in the vertical direction Z. The cover groove 133 begins at its front end facing the windshield 104 with a region that extends substantially linearly in the longitudinal direction X. A cover pin 144 of the other drive slider 130 is disposed in the cover groove 133. If the cover pin 144 moves in the linear region in the longitudinal direction X, this does not cause significant movement of the front edge 106 in the longitudinal direction X. Only when the deployment lever 109 is deployed and the rear edge 107 is raised does the cover pin 144 reach the lowered region of the cover groove 133 to open the roof opening 102. If the cover pin 144 is disposed in the lowered region of the cover groove 133, the movement of the other drive slider 130 is transmitted to the cover bracket 140 and causes the cover 103 to move in the longitudinal direction X.

[0068] The locking device 135 is implemented as a locking element 138, for example, by means of a tensile and compressive driving cable. The locking element 138 is fixedly connected to the driving slider 110 and extends forward along the longitudinal direction X. The locking element 138 is optionally connectable to or detachable from the other driving slider 130 and lockable to the guide rail 108 along the longitudinal direction X by means of a locking pin 136. The locking element 138 is guided, for example, in a locking groove 137 of the guide rail 108. To decouple from the other driving slider 130 and lock to the guide rail 108 along the longitudinal direction X, the locking pin 136 rotates, for example, about a rotation axis corresponding to the longitudinal direction X. When the locking pin 136 is connected to the other driving slider 130, it is oriented along the transverse direction Y. When the locking pin 136 is locked to the guide rail 108, it is oriented along the vertical direction Z.

[0069] Other embodiments of the locking device 135 are also possible. For example, the locking member 138 may be configured as a rigid locking lever, an elastic or flexible locking member 138, or otherwise configured. The locking member 138 and the locking device 135 are configured such that the movement of the other drive slider 130 can be temporarily transmitted to the drive slider 110, and the drive slider 110 can be immovably locked to the guide rail 108 in other states relative to the guide rail 108.

[0070] Figures 10 to 12 The device 200 is shown with the deployment lever 109 at least partially deployed. The rear end 132 of the deployment lever 109 is raised in the vertical direction Z relative to the closed position of the cover 103. For this purpose, the drive slider 110 moves in the longitudinal direction X, and the drive pin 125 moves in the drive groove 124. However, the lifting pin 123 is still located in the steeply raised area of ​​the lifting groove 122. At this point, no significant movement of the deployment lever 109 in the longitudinal direction X has occurred. Only the rear edge 107 of the cover 103 is raised. Moreover, the front edge 106 of the cover 103 has not yet moved significantly. The slider 134 (which is disposed on the cover support 140 facing outwards in the Y direction) has not yet moved significantly. The groove 114 has not yet moved significantly relative to the sliding pin 115.

[0071] Figures 13 to 15 The device 200 is shown in the open position of the cover 103. Compared to according to Figures 10 to 12 In the ventilation position, the drive slider 110 moves further rearward in the longitudinal direction X until the lifting pin 123 is positioned at the end of the lifting slide 122. Correspondingly, the drive pin 125 moves to the rear end 125 of the drive slide 124. Therefore, the unfolding lever 109 is raised to its maximum unfolded position and further moves rearward in the longitudinal direction X. For this purpose, the slide 114 also moves relative to the sliding pin 115.

[0072] The lever 119 is reliably supported not only in the open position of the cover 103, but also in the ventilated and closed positions of the cover 103, on two spaced-apart decoupling devices 111, 112. Therefore, particularly in the open position, reliable support of the force introduced into the device 200 by the open cover 103 on the guide rail 108 and subsequently on the vehicle body 105 is possible. This allows for a relatively far rearward movement of the cover 103.

[0073] In the fully open position, the slide groove 114 of the deploying lever is positioned along the longitudinal direction X before the cover pin 144. In the fully open position, the other drive slider 130 is positioned after the slide groove 114. The other drive slider 130 and the cover pin 144 are positioned along the longitudinal direction X between the two ends 131 and 132 of the deploying lever 109 in the fully open position. The other drive slider 130 and the cover pin 144 are positioned between the sliding pin 115 and the lifting pin 123 in the fully open position. In the fully open position, the elongated extended region 120 of the deploying lever 109 extends from back to front along the longitudinal direction X beside the other drive slider 130. The other drive slider 130 is positioned along the transverse direction Y beside the deploying lever 109 in the fully open position.

[0074] In particular, it is possible that the unfolding lever 109 is configured to have a rearwardly projecting region 128. This rearwardly projecting region 128 protrudes beyond the fixed rear roof member 129 in the open position of the cover. Therefore, it is possible that the support of the cover bracket 140 is relatively rearward and particularly above the fixed roof member 129. The rearward support of the cover bracket 140 as far as possible along the longitudinal direction X reduces the leverage force applied to the two coupling members 111, 112 through the cover bracket 140. The movable slider 141 (which is disposed on the rear end 132 of the unfolding lever 109 and in which the cover bracket 140 is slidably supported) is disposed above the fixed roof member 129 in the case of the open cover 103.

[0075] The fixed roof piece 129 is, for example, another cover disposed in the roof opening 102. Alternatively, the fixed roof piece 129 may be part of the vehicle body or part of the sheet metal forming the roof 101 and surrounding the roof opening 102. The device 200 is configured such that its components and other mechanical parts do not need to reach below the fixed roof piece 129 to fully open the cover 103. In particular, the other drive slider 130 only moves to, for example, the area of ​​the lifting slide 122. Even so, the cover support 140 can still achieve a large degree of rearward movement of the cover support 140 and a large degree of opening of the roof opening 102 by means of the movement of the cover slide 133 (which is disposed very far forward on the cover support 140).

[0076] Figure 18 This diagram illustrates the force and lever ratio at support points A and B of the cover when the cover 103 is open. The more rearward the front support point A, i.e., the cover slider 134, is positioned, the greater the opening degree of the roof opening 102 can be. However, a minimum interval i between support points A and B is necessary to reliably hold the cover 103. This results in a lever force because the interval l between the front support point A and the rear edge 107 of the cover 103 is significantly longer than the interval k between the front support point A and the movable slider 141 (on which the cover 103 is supported). The difference between l and k generates the lever force, and the further rearward the movable slider 141 is positioned, the smaller this lever force becomes. Therefore, the protruding area 128 enables a reduction in lever force because the ratio of k to l is improved compared to an unfolding lever that does not protrude rearward. This reduction in lever force, in turn, enables a reduction in the minimum interval i because only a small force is applied overall, and therefore the cover 103 can be reliably held even with a smaller i. Furthermore, in order to reduce the minimum interval i, an elongated unfolding lever 109 is provided, which enables the cover 103 to be supported before the support point A, as will be referred to later. Figure 19 Further clarification is needed.

[0077] Figure 19 This diagram illustrates the force and lever ratios at couplings 111 and 112 with the cover 103 open. The movable slider 141 is positioned at its rearmost point along the longitudinal direction X and above the fixed roof piece 129. That is, a lever acts on the front coupling 111 of the unfolding lever 109, generated by a distance f between two points C and B. B is the point of force application on the movable slider 141, while C is the point of force application on the sliding pin 115 and the slide rail 114. Furthermore, the force to be applied is determined by a distance 113 or e between points C and D. D corresponds to the point of force application on the lifting slide rail 122 and the lifting pin 123 on the second coupling 112.

[0078] Point B is offset backward from point D because the protruding area 128 protrudes backward. The further point B is moved backward, the smaller the force introduced onto lever 103 by the open cover 103, because the lever force based on the ratio of i to k is smaller. Figure 18Therefore, the lever effect of the cover area located after point B becomes smaller. For example, in the case of a fully open cover 103, the ratio of the interval between the cover slider 134 and the movable slider 141 to the length of the cover 103 between the cover slider 134 and the rear edge 107 is greater than 0.25, particularly greater than 0.28 or greater than 0.3. Other ratios are also possible, wherein the force acting on the movable slider 141 is as small as possible. For example, the support ratio e:f is as large as possible so that the force acting on the second coupling 112 is kept as small as possible.

[0079] The force held by the deploying lever 109 is determined specifically by the ratio f:e. The smaller the ratio f:e, the more evenly the force received by the deploying lever 109 is distributed across the points of action C and D. For example, the closer the ratio f:e is to a value of 1.0, the more evenly the force received by the deploying lever 109 is distributed across the points of action C and D. With the length of the protruding region 128 remaining constant, the more forward the first coupling member 111 is positioned, the smaller the force received at point D. With the interval between points D and B along the longitudinal direction X remaining constant, the larger the interval 113 or e between points C and D, the smaller the force received at point D.

[0080] That is, the force to be received at points A and D can be reduced not only by moving the point of action B on the sliding slider 141 backward by means of the protruding area 128, but also by the forward setting of the first coupling member 111 by means of the elongated extended area 120 of the unfolding lever 109.

[0081] Not only the first coupling member 111, but also the second coupling member 112 can be flexibly designed in terms of length and extension according to the desired opening width and the achievable force ratio by means of the implementation scheme of the grooves 114 or 122 and 124.

[0082] The support ratio on the unfolding lever 109 can be reliably adjusted to achieve a wide opening width. The support point B on the movable slider 141 for supporting the cover bracket 140 is moved rearward. The unfolding lever 109 is supported at two support points on the first coupling member 111 and the second coupling member 112. The front support point of the first coupling member 111 is supported in the unfolding lever 109 via a groove 114 and on a sliding point 115 fixed to the guide rail 108. Thus, a rotational movement of the unfolding lever 109 can be caused by a favorably selected groove guide device, which provides additional travel on the movable slider 141 and facilitates a larger support ratio for the unfolding lever 109.

[0083] Depending on positions B and C, where position D remains constant along the longitudinal direction, the respective support ratios acting on the cover bracket 140 and the unfolding lever 109 can be coordinated even with a relatively large opening width, such that the maximum support force at point D is equivalent to, for example, a conventional mechanism in which the unfolding lever, with the roof open, is oriented perpendicular to the vertical direction Z and, in particular, does not protrude rearward from the fixed roof piece 129. For example, a force acting at point D is, for instance, less than 10% greater than the force acting on the sliding slider 141 at point B, for example, between 6% and 9%. Of course, other force ratios are also possible. For example, length f is approximately 440 mm, and length e is approximately 400 mm. For example, the difference between length e and f is greater than 10 mm and less than 50 mm.

[0084] The unfolding lever 109 is driven by a drive slider 110 and by a locking device 135 for the other drive slider 130. For this purpose, a drive pin 125 is formed in the drive slider 110, which moves in a drive groove 124 in the unfolding lever 109. The drive groove 124 is configured as a cross groove relative to the lifting groove 122. Furthermore, the drive groove 124 has tolerance-compensating bosses for a closed position and a ventilated position. It is also possible to achieve any gear ratio by means of the drive groove 124. The coupling or locking between the drive slider 110 and the other drive slider 130 or the guide rail 108 is achieved, for example, by means of a locking pin 136 rotatable about a longitudinal axis or other locking device.

[0085] The mechanical energy on the front edge 106 of the cover 103 avoids the second control groove in the cover bracket 140. Only one slider 134 is applied to the cover bracket 140, which is positioned far forward on the cover 103, particularly as close as possible to the virtual axis of rotation of the cover 103. Therefore, a large opening width along the longitudinal direction X is possible. Furthermore, 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 is reduced compared to other conventional mechanisms. Therefore, complexity is reduced, and the device 200 can be implemented cost-effectively. Overall, a large natural frequency can be achieved with the cover 103 open. Lower support force can be achieved at the rear support point on the second coupling 112 of the deployment lever 109 through a longer support ratio on the deployment lever 109.

[0086] It is also possible to realize a roof 104 with only one cover for closing the roof opening 102, that is, a movable cover 103, since no mechanical component must be moved back under the fixed roof 129.

[0087] The implementation schemes of grooves 114, 122, and 124 allow for a high degree of design freedom and sufficient tolerance margin. Overall, a device 200 with a relatively small number of components can be achieved. This device 200 enables reliable opening and closing of the roof opening 102.
