Description

Device for a vehicle roof and vehicle roof

Technical Field

The invention relates to a device for a motor vehicle roof, in particular for moving a movable cover for closing a roof opening of a vehicle roof. Furthermore, a roof for a motor vehicle, in particular a roof having a device as described herein, is proposed.

Background

The device with a movable cover for the roof can be realized as a so-called spoiler roof, as described, for example, in document DE 102012106545 a 1.

It is desirable to provide a device for a vehicle roof which allows reliable operation. It is also desirable to provide a vehicle roof which allows reliable operation.

Disclosure of Invention

According to at least one embodiment, a device for a vehicle roof with a roof opening is proposed. The device has:

-a cover movable in a longitudinal direction for closing the roof opening;

-a guide rail arranged on the vehicle roof;

a deployment lever which is pivotable relative to the guide rail, wherein the cover is movable relative to the deployment lever in the longitudinal direction for opening the roof opening;

a drive slide for pivoting the deployment lever, wherein the drive slide is guided in the guide rail such that it can be displaced in the longitudinal direction;

-wherein the deployment lever has a first coupling member coupled with the rail and a second coupling member coupled with the rail;

wherein the first coupling member and the second coupling member are spaced apart from each other along the longitudinal direction and are configured such that the deployment lever section is movable relative to the rail along the longitudinal direction;

the first coupling element has a slide groove and a slide pin, which is guided in the slide groove, and the drive slide is operatively connected to the deployment lever in the region of the deployment lever assigned to the second coupling element in order to drive a pivoting and displacement of the deployment lever relative to the guide rail.

The device is designed in particular for so-called spoiler roofs. In the case of spoiler roofs, the deployment lever is first rotated or pivoted at the rear edge in the opening direction in order to lift the rear edge of the cover. The cover is moved in an opening direction relative to the deployment lever to at least partially open the roof opening. The deployment lever is fixed in relation to the rest of the vehicle roof and does not move together with the cover in the opening direction. The further the cover is moved backwards in relation to the deployment lever, the greater the force that has to be maintained by means of the deployment lever, and the greater the vibration of the cover in the case of a moving vehicle. Overcoming this has long been desired and can be improved with the solutions described herein.

This is in contrast to what is the case, for example, in the case of so-called externally guided sliding roofs, in which the deployment lever is moved together with the cover at the rear edge of the cover in the opening direction relative to the remaining roof. The above-mentioned problems do not occur here. However, such roofs cannot be used as a replacement for spoiler roofs, since they are completely different in construction and the application of spoiler roofs or externally guided roofs is dependent on the respective capacity of the vehicle base.

The deployment lever of the device described here can be moved in sections in the longitudinal direction relative to the guide rail. In addition to this, the deployment lever is lockable relative to the guide rail so as not to be taken along during the movement of the cover relative to the guide rail in the longitudinal direction. From the closed position of the cover, in which the cover closes the roof opening, the deployment lever is deflected in order to lift the rear edge of the cover (the so-called venting position). The device described here enables the deployment lever to be moved in the opening direction along a predetermined section later before the deployment lever is locked relative to the guide rail and the cover continues to be moved in the opening direction relative to the deployment lever. This enables an improved support point of the cover on the deployment lever and on the guide rail compared to the prior art. A larger natural frequency of the device, in particular of the open cover, is achievable.

A lower bearing force can be achieved at the rail-side end of the deployment lever.

The deployment lever has two coupling devices spaced apart from each other and coupled to the guide rail. A longer support ratio can thus be achieved on the deployment lever. This enables a larger opening width, i.e. a cover which is arranged relatively far back in the maximum opening position, compared to conventional spoiler mechanisms, in which the deployment lever is arranged on the guide rail only at one single point of rotation and the point of rotation is furthermore not displaceable in the longitudinal direction.

The first coupling part with the sliding groove and the sliding pin enables a rotational movement and a deflection of the deployment lever. According to one embodiment, the sliding groove is formed in the deployment lever and the sliding pin is formed in a stationary manner on the guide rail. It is also possible for the sliding pin to be formed on the deployment lever and the sliding groove in the guide rail. The first coupling member enables a connection between the deployment lever and the guide rail, which is of simple design and can therefore be realized cost-effectively. Furthermore, the first coupling element makes it possible to achieve a comparatively long support ratio on the deployment lever and a longitudinal displaceability of the deployment lever relative to the guide rail.

The drive slide is driven, for example, indirectly or directly by the motor of the device. The drive slide is arranged in the region of the deployment lever, i.e. in particular in the closed position of the cover on the rear edge of the cover. The drive slide is moved in the longitudinal direction in order to deflect and move the deployment lever in the longitudinal direction. After the end of the pivoting movement and the displacement movement, the drive slide is locked, for example, with respect to the guide rail. To close the roof opening, the drive slide is moved in the opposite direction, so that the deployment lever is moved forward and deflected back in order to close the lid.

The positional or directional indications used, such as "rear" or "front", relate to the vehicle longitudinal direction. The vehicle longitudinal direction may also be referred to as the horizontal direction or X direction of the mathematical coordinate system. The lifting or unfolding of the cover is effected substantially in the vertical or Z-direction of the mathematical coordinate system. The rear region of the cover can be understood, for example, as the region which is oriented from the center of the cover toward the rear of the vehicle.

According to at least one embodiment, the deployment lever has a shape which in the ready state is always longer in the longitudinal direction than in the transverse direction and the vertical direction. The transverse direction and the vertical direction each extend, for example, transversely to the longitudinal direction. That is, the drive slide is longer in the longitudinal direction, in particular in the vertical direction, not only in the closed state (when the cover is in its closed position) but also in the ventilation position and in the open position of the cover. This enables an advantageous support ratio for the lid in the venting position and the open position. Irrespective of the degree of deflection, the deployment lever is longer in the longitudinal direction, in particular always longer than in the vertical direction.

According to at least one embodiment, the deployment lever has a region which extends in the longitudinal direction in an elongate manner. The elongate extent of the region extends in the longitudinal direction, for example at least over 25% of the longitudinal extent of the lid in its closed position. That is, the length of the elongate expanded region is, for example, at least 1/4 of the longitudinal expansion of the lid. The length of the elongate region is dependent in particular on the 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 extension of the cover, 20% of the longitudinal extension of the cover, 30% or more of the longitudinal extension of the cover, for example up to 50% or more of the longitudinal extension of the cover.

The longer the elongate region of the deployment lever extends, the more rearward the cover-side end of the deployment lever can be moved. This enables a large natural frequency and a low bearing force and an advantageous bearing ratio. In the deflected position of the deployment lever (which is assigned to the ventilation position and/or the open position of the cover), the deployment lever expands in the longitudinal direction by a multiple, for example three, five, seven or ten times, longer than in the vertical direction. Of course, other ratios of the extent of the oblong extended area in the longitudinal direction to the extent in the vertical direction are also possible.

According to at least one embodiment, the second coupling element has a lifting runner. The lifting chute is fixedly formed on the guide rail. The second coupling has a lift pin. The lifting pin is configured on the deployment lever. The lifting pin is guided in the lifting runner. In the case where the deployment lever is moved in the longitudinal direction, the lift pin moves along the lift chute. The lifting chute has a shape such that the rear end of the deployment lever is raised and thus the deployment lever is deflected. The shape of the lifting chute furthermore also enables a longitudinal displacement of the deployment lever.

According to at least one embodiment, the deployment lever has a drive slide. The drive slider has a drive pin. The drive pin is guided in the drive slide in order to convert the movement of the drive slide into a movement of the deployment lever. The drive link has a profile which enables a movement of the rear end of the deployment lever in the vertical direction and a movement of the deployment lever in the longitudinal direction.

According to at least one embodiment, the lifting and lowering runners and the drive runner have mutually opposite directions. The lifting and lowering gate and the drive gate run at least in the closed position of the cover. The drive link has a course such that the drive link first moves away from the guide rail in the opening direction and then approaches the guide rail in the opening direction in a further course. For example, the drive link has a substantially horizontally extending region and an inclined region. It is thus possible to realize a so-called tolerance boss in which a movement of the drive pin in the longitudinal direction does not cause a movement or deflection of the spreading lever.

The adjustment link has a course such that the adjustment link extends first obliquely and then substantially horizontally in the longitudinal direction. Thus, it is possible initially to deflect the deployment lever and subsequently to move the deployment lever in the longitudinal direction in the closed position until the lifting pin reaches the rear end of the lifting chute.

According to at least one embodiment, the deployment lever has a region which projects in the longitudinal direction and which, in the open position of the cover, projects in the longitudinal direction beyond the fixed roof part. The protruding region protrudes in particular rearward. The protruding region is arranged behind the first and second coupling members in the ventilation position and the open position. In the closed position, the protruding region is arranged in front of the fixed roof part in the longitudinal direction. The displacement of the deployment lever in the longitudinal direction relative to the guide rail makes it possible to arrange this protruding region above the fixed roof part. This enables a large natural frequency and a low bearing force on the deployment lever and a longer support ratio on the deployment lever. The further the projecting region of the deployment lever projects rearward, the smaller the lever force transmitted by the cover to the deployment lever.

According to at least one embodiment, the device has a further drive carriage. The cover has a front edge which, in the closed position of the cover, extends the lever away from the front edge in the longitudinal direction. The cover has a cover runner on the front edge. For example, the lid has a lid holder and a lid runner is formed in the lid holder. The further drive slide engages into the lid slide slot in order to move the lid in the longitudinal direction. The further drive carriage is connected, for example, directly to a drive cable, which in turn transmits the drive force of the electric motor to the further drive carriage.

The drive slide and the further drive slide are in particular temporarily connected to one another in such a way that the movement of the further drive slide is transmitted to the drive slide. This enables, for example, a deflection and a displacement of the deployment lever.

The further drive slide and the drive slide can be decoupled from one another, so that the movement of the further drive slide is not transmitted to the drive slide and thus to the deployment lever. Thereby, the further drive slider is movable relative to the drive slider and the deployment lever, for example in order to move the cover between the ventilation position and the open position.

According to at least one embodiment, the device has a cover slider. The lid slider is rigidly secured to the lid. For example, the lid has a lid bracket and the lid slider is rigidly fixed to the lid bracket of the lid. The cover slider is in particular arranged so as to be non-deflectable relative to the cover or on a lever which is deflectable relative to the cover. This enables a space-saving guidance of the front edge of the cover. The virtual rotation axis of the cover between the closed position and the ventilation position may be arranged at the front as far as possible. Called the virtual rotation axis is such an axis as follows: the cover is actually deflected about this axis. This virtual axis of rotation may be different from the mechanical axis of rotation: the cover is deflectably held on the mechanical rotation shaft. This in turn enables: the lid can be moved relatively far back in the opening direction, since the mechanical means on the front edge of the lid require a small amount of space and installation space.

According to at least one embodiment, a roof for 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 dimensioned such that the roof opening is closable at least in the opening direction to the rear at the rear edge of the cover by means of the cover alone. A roof opening is, for example, an opening in a fixed roof of a motor vehicle, which fixed roof is formed from a metal sheet. The roof opening has a size and the cover has a size, which are adapted to one another in such a way that the roof opening is closable by means of the movable cover, in which the rear edge of the cover is arranged directly adjacent to the fixed roof. In the ventilation position and the open position, the projecting region of the deployment lever is therefore arranged above the fixed roof part of the vehicle roof, i.e. in particular above the sheet metal vehicle roof and not above the vehicle roof opening.

According to a further embodiment, the vehicle roof has a device according to one of the embodiments described herein. The roof has a movable cover and another cover. The movable cover and the further cover and the roof opening are dimensioned, for example, such that the cover and the further cover can be jointly arranged in the roof opening in the closed position. The movable cover and the further cover and the roof opening are dimensioned, for example, such that the roof opening can be jointly closed by means of the cover and the further cover. The further flap is arranged in the roof opening in particular in the ready state immovably relative to the remaining roof. In the closed position, the movable cover is disposed in the roof opening before the other cover, and the two covers together close the roof opening. In the open position, the movable lid is disposed above the other lid. The further cover thus still closes a part of the roof opening, in particular the rear part. In the open position, the protruding region of the deployment lever therefore protrudes beyond the further cover.

Detailed Description

Fig. 1 shows a schematic view of a roof 101 of a vehicle 100. The roof 101 is in particular part of a vehicle 100, in particular a passenger car. 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 a movement of the cover 103 in the longitudinal direction X. The cover 103 is movable for this purpose in the X direction relative to a fixed roof part 129 of the vehicle roof 101.

Fig. 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 is liftable in the vertical direction Z and movable in the longitudinal direction X in order to at least partially open the roof opening 102.

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

The deployment lever 109 is supported on the guide rail 108. The guide rail 108 is arranged along the longitudinal direction X and is connected with the body 105 of the vehicle 100 alongside the roof opening 102 in the transverse direction Y. On both sides of the roof opening 102, a guide rail 108 is provided, which carries the associated adjusting mechanism. The adjusting mechanism or device 200 is formed on both sides in the same manner or corresponding to one another. In the following only one side is described, the description correspondingly also applies to the other side of the roof opening in 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 piece 111 and the second coupling piece 112 have a spacing 113 from each other along the longitudinal direction X. The spacing 113 is, for example, at least approximately one quarter of the roof opening 112 in the longitudinal direction X, it being possible for the spacing 113 to be larger or smaller. For example, the spacing 113 is greater than 5 centimeters, particularly greater than 30 centimeters to 50 centimeters or more or less.

At the first coupling piece 111, a sliding pin 115 is formed on the guide rail 108. The slide pin 115 extends in the transverse direction Y.

The first coupling element 111 has a slide 114, which is formed in the deployment lever 109. In particular, the sliding groove 114 is formed at the first end 131 of the deployment lever 109. The first end 131 of the deployment lever 109 faces the windshield 104. The runner 114 has a substantially straight course which extends in the longitudinal direction X.

A slide pin 115 is disposed in the slide groove 114. The deployment lever 109 is thus supported on the guide rail 108 by means of the slide groove 114 and by means of the slide pin 115. The support on the first coupling piece 111 is designed such that the deployment lever 109 is movable in the longitudinal direction X. This is achieved by the chute 114. In the closed position of the cover (see also fig. 8 and 9, for example), the sliding pin 115 is arranged at the rear end of the sliding channel 114, i.e. at the end facing away from the windshield 104. In the ventilation position of the cover, and in particular in the open position, the sliding pin 115 is arranged on the front end of the sliding channel 114, i.e. on the end of the sliding channel 114 facing the windshield 104.

The second coupling piece 112 has a lifting chute 122. The lifting chute 122 is arranged in a stationary manner with respect to the guide rail 108 and is, for example, part of the guide rail 108. It is also possible for the lifting link 122 to be formed in a separate component and to fixedly connect this component to the guide rail 108.

The lift pins 123 are guided in the lift chute 122. The lift pin 123 is configured on the deployment lever 109 (see also fig. 7, 16). The profile 126 of the lifting link 122 begins at the front end in the longitudinal direction X, i.e. at the end facing the windshield 104, with a steep rise. The lifting chute 122 then has a substantially linear region extending in the longitudinal direction X. Thus, along its movement along the lifting runner 122 starting in the closed position of the lid, the lifting pin 123 is first lifted in the vertical direction Z and then moved in the longitudinal direction X without a further movement in the vertical direction Z. Accordingly, the rear end 132 of the deployment lever 109 is also first lifted substantially in the vertical direction Z and then moved in the X direction.

The movement of the deployment lever 109 is caused by driving the slider 110 (see also fig. 17). The drive slide 110 is driven in the illustrated embodiment by means of a coupling to a further drive slide 130 (fig. 3). The further drive carriage 130 is connected to the electric motor by means of a drive cable 139, for example a tension-resistant and pressure-resistant threaded cable. The drive cable 139 moves the further drive slide 130 in operation in the longitudinal direction X. This movement is transmitted to the drive slide 110 by means of the locking device 135 (fig. 6) starting from the closed position of the cover 103. That is, the drive slider also moves rearward in the longitudinal direction X.

Here, the drive pin 125 of the drive slider 110 moves along the drive runner 124 of the deployment lever 109.

The drive link 124 has a profile 127 which is opposite the profile 126 of the lifting link 122. At its front end, i.e. the end facing the windshield 104, the profile 127 of the drive link 124 initially has a horizontal region extending approximately in the longitudinal direction. This region, in which the drive pin 125 can move in the longitudinal direction X without causing a movement of the deployment lever 109, essentially serves as tolerance compensation. Next, the trend 127 is decreasing. If the drive pin 125 is arranged in this lowered region and the drive slider 110 continues to move backwards, the deployment lever 109 is lifted, since the lifting pin 123 is located in the opposite raised region of the lifting chute 122.

The profile 127 of the drive gate 124 has a further essentially horizontally oriented region in the central region, which is assigned, for example, to the position of the cover 103 in the ventilation position. The course in the longitudinal direction X is used here as a tolerance compensation. In the drive gate 124, a further drop-off region is then provided, so that the deployment lever 109 can be moved back in the longitudinal direction X into its final position. If the deployment lever 109 is completely pivoted in the vertical direction Z and moved in the longitudinal direction X, the coupling between the drive carriage 110 and the further drive carriage 130 is released. If the further drive carriage 130 is moved further in the longitudinal direction X so that the cover 103 is moved further backwards, the drive carriage 110 is locked relative to the guide rail 108 so that the drive carriage 110 and the deployment lever 109 no longer move. To close the lid 103, the movement is reversed. The further drive slide 130 can first be moved from the rear to the front relative to the drive slide 110. Subsequently, the locking device 135 couples the two

drive sliders

110, 130 to one another, so that the deployment lever 109 is pulled forward and deflected downward again.

Deployment lever 109 has shape 117. The shape 117 expands significantly more along the longitudinal direction X than along the lateral direction Y and the vertical direction Z. The deployment lever 109 therefore has a length 118 that is many times longer than a height 119 in the vertical direction Z. For example, this length 118 is also many times greater than the height 119 in the deployed position of the deployment lever 109, which is assigned to the ventilation position or the open position of the cover 103. For example, the length 118 is double, triple, quadruple, quintupled or longer up to ten times or longer than the height 119. Thereby a large spacing 113 can be achieved.

Starting from the rear region 116, which is assigned to the second coupling part 112 and is arranged at the second end 132 of the deployment lever 109, the deployment lever 109 has an elongate region 120 which extends in the longitudinal direction X in an elongate manner in the forward direction in the direction of the windshield 4. In particular, this region also extends in the extended position of the extension lever 109 in the longitudinal direction X in an elongated manner toward the front. In the closed position and the ventilation position of the cover 103, the elongate region 120 extends along a longitudinal extension 121 of the cover (fig. 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 elongate region 120 extends, in the case of the closed cover 103 and in the case of the cover 103 arranged in the ventilation position, for example, along one fifth, one quarter, one third or more, for example up to one half or up to one third, of the longitudinal extension 121 of the cover 103 in the direction of the windshield 104 in the forward direction along the longitudinal direction X.

The deployment lever 109 has a closing slot 142 in the rear region 116. The closing groove 142 opens rearward in the longitudinal direction X. The drive shoe 110 has a closing pin 143. The closing pin 143 is disposed in the closing groove 142 in the closed position of the cover 103. To close the cover 103 from the ventilation position, the deployment lever 109 is pulled down in the vertical direction Z and held in the vertical direction Z by means of the closing pin 143. Therefore, the cover 103 can be reliably closed and reliably held in the closed position even under strong force.

The cover 103 has, for example, a cover holder 140. The cover has, for example, a planar panel, in particular a glass panel. A cover bracket 140 is provided on the panel. The cover bracket 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 on the cover holder 140 and is in particular not pivotable relative to the cover holder 140. It is possible that the lid slider 134 is rotatable relative to the lid holder 140 about a rotational axis (which extends in the transverse direction Y). However, according to an embodiment, the cover slider 134 is immovable with respect to the cover bracket 140 along the longitudinal direction X and/or the vertical direction Z. The cover slider 134 is guided in the guide rails 108 and serves to lift and move the front edge 106 of the cover 103.

A cover slide 133 is formed on the cover carrier 140 in order to raise and lower the front edge 106 of the cover in the vertical direction Z. The cover gate 133 initially has, at its front end facing the windshield 104, a region which extends substantially linearly in the longitudinal direction X. The cover pin 144 of the further drive slide 130 is arranged in the cover slot 133. If the cover pin 144 is moved in the linear region in the longitudinal direction X, this does not yet cause a 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, the cover pin 144 reaches the lowered region of the cover link 133 for opening the roof opening 102. If the cover pin 144 is arranged in the lowered region of the cover slide 133, the displacement movement of the further drive slide 130 is transmitted to the cover holder 140 and the cover 103 is displaced in the longitudinal direction X.

The locking device 135 is realized as a locking element 138, for example, by means of a tension-resistant and pressure-resistant drive cable. The locking element 138 is fixedly connected to the drive slide 110 and extends forward in the longitudinal direction X. The locking element 138 is optionally connectable to the further drive carriage 130 or releasable from the further drive carriage 130 by means of the locking pin 136 and lockable with the guide rail 108 in the longitudinal direction X. The locking element 138 is guided, for example, in a locking groove 137 of the guide rail 108. In order to be decoupled from the further drive carriage 130 and locked with the guide rail 108 in the longitudinal direction X, the locking pin 136 is rotated, for example, about a rotational axis, which corresponds to the longitudinal direction X. In a state where the locking pin 136 is connected with the other drive slider 130, the locking pin 136 is oriented in the lateral direction Y. In a state where the locking pin 136 is locked with the guide rail 108, the locking pin 136 is oriented in the vertical direction Z.

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

Fig. 10 to 12 show the device 200 in the case of an at least partially unfolded deployment lever 109. The rear end 132 of the deployment lever 109 is lifted in the vertical direction Z compared to the closed position of the cover 103. For this purpose, the drive slider 110 is moved in the longitudinal direction X and the drive pin 125 is moved in the drive chute 124. However, the lift pins 123 are still disposed in the steep rise regions of the lift chute 122. No significant movement of the deployment lever 109 in the longitudinal direction X has yet occurred here. Only the rear edge 107 of the cover 103 is lifted. Moreover, the front edge 106 of the cover 103 has not moved significantly. The slider 134 (which is disposed on the cover bracket 140 facing outward in the Y direction) has not moved significantly. The runner 114 has not moved significantly relative to the slide pin 115.

Fig. 13 to 15 show the device 200 in the open position of the cover 103. In contrast to the ventilation position according to fig. 10 to 12, the drive carriage 110 is moved further back in the longitudinal direction X until the lifting pin 123 is arranged at the end of the lifting link 122. Accordingly, the drive pin 125 moves to the rear end 125 of the drive chute 124. Thus, the deployment lever 109 is lifted to its maximum deployment position and is furthermore moved backwards in the longitudinal direction X. For this reason, the slide groove 114 also moves relative to the slide pin 115.

The deployment lever 119 is supported securely on the two spaced-apart

decoupling devices

111, 112 both in the illustrated open position of the cover 103 and in the ventilation position and the closed position of the cover 103. Thus, in particular in the open position, a reliable support of the forces introduced into the device 200 by the open cover 103 on the guide rail 108 and thus on the body 105 is possible. A relatively far rearward movement of the cover 103 is thereby achieved.

In the fully open position, the chute 114 of the deployment lever is disposed in front of the cover pin 144 along the longitudinal direction X. In the fully open position, the further drive slide 130 is arranged behind the slide groove 114. The further drive slider 130 and the cover pin 144 are arranged between the two ends 131, 132 of the deployment lever 109 in the fully open position along the longitudinal direction X. The further drive slider 130 and the cover pin 144 are arranged between the slide pin 115 and the lifting pin 123 in the fully open position. In the fully open position, the elongate expanded region 120 of the deployment lever 109 extends along the longitudinal direction X from the rear to the front past the further drive carriage 130. The further drive slider 130 is arranged alongside the deployment lever 109 in the transverse direction Y in the fully open position.

In particular, it is also possible for the deployment lever 109 to be formed with a region 128 which projects rearward. The rearward projecting region 128 projects beyond a fixed rear roof part 129 in the open position of the cover. It is thus possible for the support of the cover bracket 140 to be relatively rearward and in particular above the fixed roof part 129. The support of the cover carrier 140 as far to the rear as possible in the longitudinal direction X reduces the lever force exerted by the cover carrier 140 on the two

couplings

111, 112. A moving slider 141 (which is provided on the rear end 132 of the deployment lever 109 and in which a cover bracket 140 is slidingly supported) is provided above the fixed roof part 129 in the case of an open cover 103.

The fixed roof part 129 is, for example, a further cover which is arranged in the roof opening 102. It is also possible that the fixed roof part 129 is part of the body of the vehicle or of a panel forming the roof 101 and surrounding the roof opening 102. The device 200 is constructed such that the components of the device 200 and additional mechanical components do not have to reach under the fixed roof member 129 to fully open the lid 103. In particular, the further drive carriage 130 is only moved up to the region of the lifting chute 122, for example. Even so, the movement of the cover carrier 140 by means of the cover runner 133 (which is arranged very far forward on the cover carrier 140) still enables a large rearward movement of the cover carrier 140 and a large opening of the roof opening 102.

Fig. 18 shows a schematic illustration of the force and lever ratio at the support points a and B of the cover in the case of an open cover 103. The greater the rearward extent of the front support point a, i.e. in particular of the cover slider 134, the greater the extent to which the roof opening 102 can be opened. However, a minimum interval i between the support points a and B is necessary so that the cover 103 can be reliably held. The resulting lever force is exerted because the distance l 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 slider 141 on which the cover 103 is supported. The lever force is generated by the difference between l and k, and is smaller the farther the moving slider 141 is disposed. Thus, the protruding region 128 enables a reduction of the lever force, since the ratio of k to l is improved compared to a deployment lever that does not protrude backwards. The reduction in the lever force in turn enables a reduction in the minimum spacing i, since overall only a small force acts and therefore the cover 103 can be held securely even with a smaller i. Furthermore, in order to reduce the minimum spacing i, an oblong spreading deployment lever 109 is provided, which enables the support of the cover 103 in front of the support point a, as will be explained further below with reference to fig. 19.

Fig. 19 shows a schematic illustration of the force and lever ratio at the

couplings

111, 112 with the cover 103 open. The moving slider 141 is disposed at its rearmost position in the longitudinal direction X and is positioned above the fixed roof member 129. That is, a lever, which is produced by the spacing f between the two points C and B, acts on the front coupling 111 of the deployment lever 109. B is the point of application of the force to the sliding slide 141, and C is the point of application of the force to the sliding pin 115 and the sliding groove 114. Furthermore, the force to be introduced is determined by the spacing 113 or e between points C and D. D corresponds here to the force application point on the second coupling part 112 on the lifting link 122 and the lifting pin 123.

Point B is set offset rearward with respect to point D because the protruding region 128 protrudes rearward. The further back point B is moved, the smaller the force introduced by the opened cover 103 onto the lever 103, since the smaller the lever force occurs on the basis of the ratio of i to k (fig. 18). Thereby the leverage of the cover area arranged after point B becomes smaller. For example, in the case of a completely open cover 103, the ratio of the distance between the cover slider 134 and the displacement slider 141 to the length of the cover 103 between the cover slider 134 and the rear edge 107 is greater than 0.25, in particular greater than 0.28 or greater than 0.3. Other ratios are also possible, wherein the forces acting on the moving slider 141 are as small as possible. For example, the support ratio e: f is as large as possible in order to keep the forces acting on the second coupling member 112 as small as possible.

The force to be held by the deployment lever 109 is in particular given by the ratio f: e, determining. The ratio f: the smaller e, the more evenly the force to be received by the deployment lever 109 is distributed to the points of action C and D. The ratio f: e.g. closer to the value 1.0, the more evenly the force to be received by the deployment lever 109 is distributed over the points of action C and D. The further forward the first coupling member 111 is provided, the smaller the force to be received at point D, with the length of the protruding region 128 remaining constant. In the case where the interval between the points D and B in the longitudinal direction X is kept constant, the larger the interval 113 or e between the points C and D, the smaller the force to be received at the point D.

That is, the forces to be received at the points a and D can be reduced not only by moving the point of action B on the displacement slider 141 rearward by means of the protruding region 128, but also by the first coupling piece 111 being arranged forward by means of the extent of the elongate expanded region 120 of the deployment lever 109.

The realization of both the first coupling part 111 and the second coupling part 112 by means of the slotted

link

114 or 122 and 124 enables a flexible design of the respective length and extension depending on the desired opening width and the achievable force ratio.

The support ratio on the deployment lever 109 can be set reliably such that a wide opening width can be achieved. The supporting point B for supporting the cover bracket 140 on the moving slider 141 is moved backward. The deployment lever 109 is supported on a first coupling element 111 and a second coupling element 112 at two support points. The front bearing point of the first coupling element 111 is supported in the deployment lever 109 via a sliding groove 114 and on a sliding point 115 fixed to the guide rail 108. A rotary movement of the deployment lever 109 can thus be brought about by the advantageously selected slotted guide, which takes up an additional stroke on the displacement slider 141 and facilitates a comparatively large support ratio of the deployment lever 109.

Depending on the positions B and C in the case of the position D, which is not changed in the longitudinal direction, the respective support ratios acting on the cover carrier 140 and on the deployment lever 109 can be adjusted to one another even in the case of a comparatively large opening width in such a way that the maximum support force acting at the point of action D is, for example, equivalent to a conventional machine in which the deployment lever, in the case of an open roof, is oriented perpendicularly to the vertical direction Z and in particular does not project rearward beyond the fixed roof part 129. For example, a force acts on the point of action D which is, for example, less than 10%, for example between 6% and 9%, greater than the force acting on the moving slider 141 at point B. Of course, other force ratios are possible. For example, the length f is about 440 millimeters and the length e is about 400 millimeters. For example, the difference between lengths e and f is greater than 10 millimeters and less than 50 millimeters.

The drive of the deployment lever 109 is effected by means of the drive carriage 110 and by means of the locking device 135 for the further drive carriage 130. For this purpose, a drive pin 125 is formed in the drive slider 110, which pin moves in a drive slot 124 in the deployment lever 109. The drive link 124 is configured as a cross link with respect to the lift link 122. Furthermore, the drive gate 124 has tolerance compensation projections for the closed position and for the ventilation position. Furthermore, it is possible to realize any desired transmission ratio by means of the drive gate 124. The coupling or locking between the drive carriage 110 and the further drive carriage 130 or the guide rail 108 is effected, for example, by means of a locking pin 136 or other locking means which can be rotated about a longitudinal axis.

The mechanical energy at the front edge 106 of the cover 103 avoids the second control slot in the cover bracket 140. Only a single slider 134 is applied to the cover holder 140, which slider 134 is positioned far forward on the cover 103, in particular 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 reducible compared to other conventional machines. The complexity is reduced and the device 200 can be implemented cost-effectively. Overall, a large natural frequency can be achieved with an open cover 103. In the rear bearing point on the second coupling part 112 of the deployment lever 109, a lower bearing force can be achieved by a longer bearing ratio on the deployment lever 109.

It is also possible to realize a vehicle roof 104 with only one cover for closing the roof opening 102, i.e. a movable cover 103, since no mechanical components have to be moved back under the fixed vehicle roof 129.

The embodiment with the aid of the slotted guides 114, 122 and 124 allows a large degree of freedom in design and sufficient tolerance. Overall, a device 200 with a relatively small number of components can be realized. The device 200 enables reliable opening and closing of the roof opening 102.
