Pin 13 in engagement. The slot guide 11 has a first section 14, which compensates for the relative movement between the cover and the arc-segment-shaped carrier is assigned when the cover 3 is pivoted out or in. At this first section 14 of the slot guide 11 is angled and directed downwards to another section 15, which is down and in the Closed position, located lid 3 is aligned parallel to the plane of movement of the arc-segment-shaped carrier Io. In the area of its free, however, on section 15 of slot guide 11 there is a recess 16 that is open at the bottom connected. The slot guide 11 is in the embodiment shown housed overall in a block 17 attached to the cover 3 in a vertical orientation. The arc-segment-shaped carrier Io has according to the illustration in Figure 5 a double T-shaped profile cross-section on and is via its profile flanges 18 and 19 to the corresponding Bearing surfaces 2o and 21 of the plain bearing 9 out. The arc-segment-shaped carrier Io also has a In extension of its central web 22 formed toothing 23, over which it is in meshing engagement with the threaded cable 12 stands. The arc-segment-shaped carrier Io can therefore be driven directly via the threaded cable 12 will. As can be seen in particular from the illustration of Figure 1, the two lifting devices 2 by means of a Hand crank 24 and a gear 25 driven in opposite directions Threaded cable 12 assigned, which in the area of its drive-side end with one each of the closed position of the cover 3 defining stop 25 are provided.

Carrier Io is moved further in section 15 of slot guide 11 is until the pin 13 finally reaches the area of the recess 16, which is open at the bottom, and thus the lifting device is disengaged from the cover-side slot guide 11. In this position, the lid can completely be removed.

A first embodiment of a vehicle roof 1 provided with a roof cutout 2 closable by means of a rigid cover 3 is shown in FIGS Sliding roof cassette 3o can be pushed under the rigid part of the vehicle roof 1. In the area of its front end 5, the cover 3 is supported so as to be pivotable about an axis 21 directed transversely to the direction of travel on supports 33 guided in guide rails 32 basically laid in the sliding roof cassette 3o. In the region of its rear end, the cover 3 is supported on each of its two longitudinal sides via a lifting device, which in turn is arranged on a slide arranged in the guide rails 32 so as to be longitudinally displaceable. Each of the two lifting devices comprises an arcuate segment-shaped carrier lo which is slidably arranged in correspondingly shaped slide bearings 9 and which carries a pin 13 at one end, which in turn engages in a slot guide 11 arranged in a vertical orientation on the cover 3. The drive of the arcuate segment-shaped carrier Io takes place by a threaded cable 12, with which it is in meshing engagement via a toothing 23. The slot guide, generally designated 11, here comprises a first section \ k associated with the relative movement between the arcuate support Io and cover 3 when the cover 3 is raised or swung in, and a downwardly directed section 15 at an angle adjacent to this, which is in its to the roof level aligned position cover 3 is used to lock the cover 3 in this position and another on

the section 15 adjoining, upwardly directed section 34, which a lowering of the lid 3 in one of the roof level lowered downwards, moving the cover 3 under the roof of the vehicle permitting location allows. A short section 15 connected to the section of the slot guide 11 is used only to compensate for tolerances or to fix the cover in its lowered sliding position. At in its lowered sliding position shown in FIG Carrier Io for longitudinally moving the cover 3 as a drive connection to the threaded cable 12. The cover 3 when moving into its open position by the arcuate segment Carrier Io pulled and pushed into its congruent position to the roof cutout 2 when moving. To a unintentional lifting of the cover 3 while it is being pushed into its congruent roof cutout 2 To prevent the situation with certainty, a first stop arrangement is assigned to the arcuate segment-shaped carrier 3, which consists of a slide 36 which supports the lifting device against the guide rail 32 pivotably articulated and in the embodiment shown is formed by a pawl 38 loaded against the slide 36 supported by a spiral compression spring 37. the At its end opposite the compression spring 37, the pawl 38 has an upwardly directed, in its angular position the plane of movement of the arcuate carrier Io intersecting the locking nose 39. On the other hand, owns the pawl 38 of the locking lug 39 opposite a downwardly directed cam '+ o, which is on the bottom the sliding roof cassette 3o arranged guide rail 32 slides and which has a recess 41 in the upper Profile flange of the guide rail 32 is assigned ^. The recess 41 in the guide rail 32 is arranged so that that the cam 4o of the pawl 38 is only at

located in congruent position to the roof cutout 2 Lid 3 is located directly above recess 41. This ensures that the freedom of movement of the arcuate segment-shaped carrier Io through the locking lug 39 the pawl 38 remains locked in the direction of lifting the cover 3 until the cam 41 of the pawl 38 is located directly above the recess 4o in the guide rail 32. Only in this situation which one at the same time that defines the congruent position of the cover 3 with the roof cutout 2, the pawl 38 pivoted and thus the locking lug 39 is pivoted out of the plane of movement of the arc-segment-shaped carrier Io will. Therefore, the arcuate segment-shaped carrier Io with the cover 3 congruent with the roof cutout 2 by the threaded cable 12 in the sense an advancement of the cover 3 is driven further, the pawl 38 can by the over an arcuate Abruni ung at its likewise arc-shaped rounded locking nose 39 adjacent front end of the arc-segment-shaped Carrier Io are pushed down and thus out of its trajectory. In this position the The pawl 38, which is shown in Figure 6, the lid in the region of its rear end through the Lifting device are raised. To limit the maximum height of the cover 3 is another Stop arrangement is provided which is fixed immovably from a carriage 36 which carries the lifting device Stop 42 and one arranged on the arcuate segment-shaped carrier Io at a distance from its end on the cover side Stop surface 43 is made. As can be seen in particular from the illustration in FIG. 8, the arcuate segment comes ment-shaped carrier Io with the cover 3 exhibited in the maximum permissible position with its stop surface on the stop 42 in contact, 'whereby the further freedom of movement of the arcuate segment-shaped carrier Io in The opening direction of the cover is blocked.

a vehicle roof 1 provided with a roof cutout 2 that can be closed by a cover 3, the cover 3 on the one hand around a pivot bearing in the area of its front end 5 in an exposed ventilation position and on the other hand after lowering below the roof level to completely release the roof cutout 2 under the vehicle roof 1 can be moved. In this embodiment, too, the cover 3 is supported in the region of its rear end via a lifting device on a sliding roof cassette 3o. The lifting device here also essentially comprises an arcuate segment-shaped carrier Io and a correspondingly shaped slide bearing 9 in which the arcuate segment-shaped carrier Io is supported in a longitudinally displaceable manner. The arc-segment-shaped carrier Io engages on the cover 3 via a laterally protruding pin 3 and a slot guide 11. The design of the slot guide 11 and its arrangement corresponds to that according to the previously described embodiment according to FIGS. In contrast to the embodiment described in detail in the previous embodiment, in the embodiment according to FIGS. The threaded cable 52 is guided within a block 53 receiving the sliding bearing 9 , approximately from the middle of the sliding bearing 9 to its course, so that it follows the path of movement of the arcuate segment-shaped carrier Io. As a result, the arcuate segment-shaped carrier Io is driven directly by the advance or return movement of the threaded cable 52. The slide bearing 9

In the exemplary embodiment shown, the receiving block 53 is arranged together with the two stop arrangements and the pivot bearing of the cover, which is arranged in the region of the front end of the cover, on a common slide 54, which can be displaced as a whole by the threaded cable 52. Via the block 53, the threaded cable 52 engages the slide 5k directly with its front end 5k by means of a spring 55. Starting from the position of the cover 3 shown in FIG. Io, which is aligned with the roof plane, when the threaded cable 52 is driven in the sense of a displacement of the cover 3 over the front end 5o of the cable 52, the arc-segment-shaped carrier Io is initially moved backwards by the free path 56, whereby, as a result of the engagement of the pin 13 at the front end of the arcuate segment-shaped carrier Io in the section 34 of the slot guide on the cover side, the cover 3 is lowered down into a displacement position. After passing through the free path 56, the front end 5o of the threaded cable 52 comes to rest on the leg 57 of the spring 55 designed as a leg spring, whereby if the threaded cable 52 is further driven in the same direction, the leg spring 55 is initially tensioned and then the entire slide including the sliding roof cover 3 along the guide rails 32 is basically moved to the rear of the sliding roof cassette 3o and thus the sliding roof cover 3 is increasingly brought under the roof 1 of the vehicle. When the threaded cable 52 is driven in the opposite direction, the arched segment-shaped carrier Io transmits its thrust force to the cover 3, so that the latter is increasingly displaced forwards until it reaches its position which is congruent with the roof opening 2. During this advancing movement of the cover 3, the freedom of movement of the arc-segment-shaped carrier Io in the direction of erecting the cover 3 is canceled by the first stop arrangement, the pawl 38 and its locking lug 39, which cuts the plane of movement of the arc-segment-shaped carrier Io. Only when the cover 3 is in congruent position with the section 2 does the cam ko of the pawl 38 come with it

associated recess 41 in the guide rail 33 and thus the freedom of movement of the arcuate segment-shaped carrier Io in the direction of issuing of the cover 3 released. In the embodiment shown here, the cam 4o of the pawl 38 are further on rearward course of the guide rails 32 arranged partial recesses 58 assigned, in which the cam snap into place and thereby prevent the cover 3, which is in any shifting position, from slipping, in particular as a result of unusual delays in the vehicle. The depth of the recesses is dimensioned so that by locking the cam 4o of the locking pin ^^ 38 freedom of movement of the arcuate segment carrier Io in the direction of issuing of the cover 3 is not yet released. The cover 3 is in the area of its front end displaced pivotably in the slide 54 via an axis 59 directed transversely to the direction of travel. The pivot axis of the cover 3 is also assigned a slot recess 6o in the web of the carriage 54, which is a longitudinally Shifting of the pivot axis 59 when the cover 3 is raised or pivoted in is made possible. The pivot axis 59 is also to be held in its starting position corresponding to the closed position of the cover 3, searching compression spring 61 assigned. The compression spring 61 is on the other hand on an abutment flange 62 of the carriage supported. In the embodiment shown here, as can be seen in particular from the illustration in FIG. 15, the entire drive mechanism of the cover 3 within the same arranged and housed in a housing 64 fastened to the inner cover plate. The drive mechanism comprises a rotary handle 65 and drive means for the threaded cables 52. The threaded cables 52 are, as can be seen in particular from the representations of Figures Io to 11 and 13, through the pivot bearing axis 59 of the cover out of the lid and into the carriage 54 carrying both lids. From the representation of the Figure 15 can also be seen that the sliding roof cover

Another embodiment is shown in FIGS a vehicle roof 1 provided with a roof cutout 3 closable by means of a cover 3 is shown, wherein the cover 3 on the one hand about a pivot axis arranged in the region of its front end 5 in an open position and on the other hand after lowering into a sliding position to completely release the roof cutout 2 under the Vehicle roof 1 can be moved. In the embodiment shown here, the cover is driven 3 via a drive element arranged in particular in the center of the vehicle, for example formed by a threaded cable, and a drive element displaceable on the guide rails 32 guided sliding bridge 7o. The drive connection between the sliding bridge 7o and the cover 3 is segment-shaped Carriers Io taken over, which are longitudinally displaceable in a correspondingly shaped sliding bearing 9 are included, üei the embodiment shown here the slide bearing 9 and the pivot bearing arranged in the region of the front end of the cover 3 are on a common one Carriage 71 is arranged to be longitudinally displaceable on the guide rails 32 in the sliding roof cassette 3o. Even with this one Embodiment is the arcuate segment-shaped carrier Io by means of a pin 13 and one which has already been described in detail above and is arranged on the cover 3 Slot guide 11 connected to the cover 3. In this embodiment, the arc-segment-shaped carrier transmits Io the thrust and tensile forces exerted on this by the drive element from the sliding bridge 7o to the cover 3. The Arched segment-shaped carrier Io is here on the sliding bridge 7o received in a slightly curved, substantially vertically aligned slot guide 72, wherein the ends of the slot guide 72 form stops.

whereby the cover 3 is lowered over the arcuate segment-shaped carrier Io downward into its sliding position in that the pin 13 cooperates with the section 34 of the slot guide 11. At the same time, the end of the arched segment-shaped carrier Io comes into contact with the upper end of the slot guide 72 and the stop provided there, so that a further lowering of the cover 3 is not possible when the sliding bridge 7o is moved further backwards. In this position, the arcuate segment-shaped carrier Io is also locked in the opposite direction by a pawl 73 in its freedom of movement in the direction of the cover 3 being raised. The pawl is pivotably articulated on the slide 71 and has, on the one hand, a locking nose Tk and, on the other hand, a cam 75. The cam 75 is assigned a recess 76 in the profile base of the guide rail 32, which is arranged so that the cam 75 can only engage when the sliding roof cover 3 is in a congruent position with the roof opening 2. In addition, the cam slides on the bottom of the guide rail 32, so that the pawl 73 assumes a position in which its locking nose intersects the plane of movement of the arcuate carrier Io. This locking arrangement ensures that when the sliding roof cover is advanced, this thrust force of the sliding bridge 7o, which is transmitted through the intermediary of the carrier Io, cannot be raised from its lowered sliding position. In the exemplary embodiment shown in FIGS. 16 to 23, the pawl 73 is loaded by a leaf spring 77 which is articulated at its front end to the pivot bearing axis 59 of the cover 3 and which, at a distance from its articulation at 59, is longitudinally wearable on a slide 71 trained abutment 78 supported 1st.
