The The invention relates to a folding roof of a motor vehicle according to the preamble of claim 1

Such a folding roof is from the document DE 600 14 788 T2 known. This folding roof comprises a foldable fabric blank, by means of which a roof opening can optionally be closed or released. The fabric blank is bounded on the bow side by an actuating beam, which is displaceably guided on both sides in each case via a sliding element in a guide rail in the vehicle longitudinal direction. Rear side of the actuating beam transverse beams are arranged, which are guided displaceably on both sides arranged slider in the vehicle longitudinal direction. The folding roof further comprises Ausstellspriegel, which are each connected via a stay arm with the actuating beam or with one of the crossbars. In a the opening opening at least partially releasing opening position the Ausstellspriegel against the operating beam or the respective cross-bow are issued. The Spriegelgleiter are each provided with a connecting element that locked in the closed position of the folding roof the respective Spriegelgleiter on the associated guide rail and releases the relevant Spriegelgleiter against the guide rail when releasing the roof opening.

From the publication DE 202 14 460 U1 a folding roof is known that has a fold-cut fabric blank and sliding elements, which are guided on guides and to each of which a Ausstellbügel is articulated, which causes a folding of the fabric blank when opening the folding roof. When opening the folding roof, the fabric blank is folded successively.

From the publication DE 1 688 252 U a folding roof is known which has a fabric blank, which is adjustable by means of slider elements between an open position and a closed position, which are arranged on a guide arrangement in the vehicle longitudinal direction one behind the other. In the closed position of the fabric blank, the slider elements are secured by means of a locking device on the respective guide rail.

From the publication DE 44 11 387 C2 Also, a folding roof of a motor vehicle is known, in which a foldable fabric blank can be folded folded. The folding takes place by means of a slider / handlebar arrangement, wherein two in the vehicle longitudinal direction successively arranged slider are each coupled via a link assembly of a short and a long arm with each other. A front slider is driven causing a backlash of all the sliders and the handlebar assembly. First, then the rear-mounted arm assembly is actuated, the short arm is unsecured. As a result, the next sliding element in the vehicle longitudinal direction is moved against the rear-side sliding element, which in turn has a pivoting of a locking element result, so that the short arm of the next link assembly is released and engages a leg of the locking element in a recess of the rear-side slider. Successively takes place in this way a release and actuation of the other link assemblies for folding the fabric blank.

From the DE 40 39 583 A1 a folding roof is known which comprises a foldable fabric blank, by means of which a roof opening can optionally be closed or at least partially released. The fabric blank is bounded on the vehicle side by a rigid roof top, which is guided displaceably on both sides in each case via a slider element in a guide rail in the vehicle longitudinal direction, as well as in the closed position by several cross beams under tension, which are arranged on the rear side of the roof top and arranged on both sides Deflection glides are guided in the vehicle longitudinal direction slidably in the guide rails. At the Spriegelgleitern a release lever is arranged in each case, which is connected to a Ausstellspriegel, which dictates the folding of the fabric blank in its release position and this is issued to the crossbeam.

Of Furthermore, it is known from practice, a folding roof with a mechanism to train for controlled wrinkling. Under a mechanics to regulated Wrinkling is a mechanism to understand when opening the Folding roof produced folds of the fabric blank in a controlled, d. H. controlled sequence can be generated. A well-known mechanics for regulated wrinkling includes a rooftop, crossbar and Ausstellspriegel for tensioning and controlled folding of the fabric blank. The rooftop and crossbars are linear in the guide rails guided and can be over pressure stiff Drive cable in the vehicle longitudinal direction be moved. In closed position the fabric blank are the Ausstellspriegel, with the crossbeams are connected, by engaging in link tracks against guide rails secured, in which the rooftop and the crossbeams are guided. All Bow and the rooftop are coupled together via handlebars. this leads to to a complex mechanics.

In an unregulated wrinkling the cross beams, however, are not locked in the closed position of the roof opening system on the guide rails, resulting in a flutter of Stoffzu cut and thus can lead to unwanted noise.

In the 1 to 11 is a vehicle roof 10 shown, for closing or at least partially releasing a roof opening, not shown, designed as a folding roof roof opening system 12 having, with a foldable fabric blank 14 is provided.

For operation, the roof opening system 12 a mechanism by means of a controlled wrinkling of the fabric blank is guaranteed when releasing the roof opening.

The roof opening system 12 comprises a rooftop extending in the vehicle transverse direction, which is designed as a crossbeam and the fabric blank 14 limited at its vehicle bend end. In the in 1 shown closed position is the rooftop 16 sealingly on a front cowl, not shown, of the vehicle roof 10 at.

The rooftop 16 includes a carrier relative to a vehicle longitudinal median plane on both sides 18 that has one out of two handlebars 20 and 22 formed four-joint on a slide plate 24 is pivotally mounted. The with a drive cable 30 connected slider plate 24 is again via sliding elements 26 in the vehicle longitudinal direction in a roof-fixed guide rail 28 slidably guided.

Relative to a vehicle longitudinal median plane is the roof opening system 12 formed mirror-symmetrically. Therefore, the roof opening system will be described in the following only with reference to the left in the direction of travel actuating mechanism.

The roof opening system designed as a folding roof 12 also includes two guided, each with the fabric blank 22 connected crossbars 36A . 36B , Which in each case with respect to the vehicle longitudinal center plane laterally arranged Spriegelgleiter 38A respectively. 38B also in the guide rails 28 are guided displaceably in the vehicle longitudinal direction. In the in 1 shown closed position of the fabric blank 14 are the bowing gliders 38A and 38B the crossbar 36A and 36B each in the appropriate position on the guide rails 28 locked. There is no mechanical connection between the crossbeams 36A and 36B or between these and the rooftop 16 in front.

At the bowling gliders 38A and 38B the crossbar 36A and 36B is the rear side in each case a Ausstellarm forming Ausstellfeder 40A respectively. 40B arranged, which is designed as a leaf spring and at its respective transverse bow 36A respectively. 36B opposite end one with the fabric blank 22 connected Ausstellspriegel 42A respectively. 42B wears on which the fabric cut 14 is clamped in the closed position and in the relaxed state of the fabric blank 22 by the effect of the relevant deployment spring 40A respectively. 40B opposite the crossbeams 36A and 36B turns up and so the folding of the fabric blank 14 in release order pretends.

As in particular the 4 to 11 it can be seen, the slider plate 24 the rooftop 16 two spaced apart in the vehicle longitudinal direction, rectangular recesses 44 and 46 on, in the vehicle vertical direction, that is transverse to the guide rail 28 are slightly offset from each other and of which the Fahrzeugbugseitige recess 44 the bow-side crossbar 36A and the vehicle rear recess 46 the rear crossbar 36B assigned.

At the bowling gliders 38A and 38B is, in particular the 8th to 11 it can be seen, a transversely arranged in the vehicle transverse direction bolt 48 arranged, with the respective recess 44 respectively. 46 the slider plate 24 the rooftop 16 interacts. The respective bolt stone 48 of the bowling glider 38A respectively. 38B is for example in one at the respective Spriegelgleiter 38A respectively. 38B trained windows 50 , which has a substantially rectangular floor plan, slidably guided in the vehicle transverse direction and has at its rear-side end two operating ramps 52 and 54 on, in cooperation with the guide rail 28 or the edge of the window 50 the bolt 48 in vehicle transverse direction. In the in 1 shown closed position are the locking blocks 28 the bowing glider 38A and 38B each in engagement with a corresponding latch recess 56 the guide rail 28 ,

The in the 1 to 11 illustrated folding roof mechanism with controlled wrinkling works in the manner described below.

Starting from the in 1 illustrated closed position, in which the fabric blank 14 is curious and the guided bow gliders 38A and 38B each by engagement of the associated locking block 48 in the relevant locking recess 56 the guide rail 28 is locked by pressing the drive cable 30 First of all from the handlebars 20 and 22 formed four-bar linkage, leaving the rooftop 16 pivoted upwards and the fabric cut 14 between the rooftop 16 and the vehicle-side, guided crossbeam 36A is relaxed. Subsequently, the rooftop 16 by means of the slider plate 24 moved in the vehicle rear direction, so that the slider plate 24 on the bowing glider 38A of the vehicle bend-side crossbar 36A ascends. As a result, a force acting in the vehicle rear direction force on the locking block 48 of the bowling glider 38A exercised. By interaction of the relative to a vehicle longitudinal center plane outside actuation ramp 54 with the rear edge of the associated locking recess 56 the guide rail 28 learns the bolt stone 48 an offset in the direction of the vehicle longitudinal center plane, so that it in the Fahrzeugbugseitige recess 44 the slider plate 24 intervenes. This will make the bowing glider 38A from the guide rail 28 unlocked and with the slider plate 24 locked. By another method of the slide plate 24 in the vehicle rear direction of the crossbeam 36A get picked up. This relaxes between the vehicle rebound side crossbeam 36A and the vehicle rear side, guided crossbeam 36B arranged area of the fabric blank 14 , so that the Ausstellspriegel 42A by the action of the extension spring 40A opposite the crossbar 36A can exhibit.

As in the 6 and 7 then the roof top is displayed 16 and the crossbar 36A Continue to drive the formed Spriegel package towards the rear of the vehicle until it reaches the rear-side, guided crossbar 36B ascends. As a result, according to the unlocking and locking of the front cross bar 36A the rear crossbar 36B from the guide rail 28 unlocked and with the slider plate 24 locked. This is done in turn by the fact that a bolt 48 in a bar recess 56 the guide rail 28 engages, experiences an offset in the direction of the vehicle longitudinal center plane and thereby in the rear-side recess 46 the slider plate 24 engages and the bowing slide 38B with the slider plate 24 locked. Another method then out of the crossbeams 36A and 36B and the rooftop 16 Existing Spriegelpakets towards the rear of the vehicle leads to a relaxation of the rear of the crossbeam 36B arranged portion of the fabric blank 14 , so that the Ausstellspriegel 42B by the action of the extension spring 40B can exhibit.

The procedure of the roof opening system 12 in the closed position, in which the fabric blank 14 the roof opening closes, takes place in respect of the functions described above in the reverse manner. To prevent that here the front crossbeam 36A at the for the rear crossbar 36B intended position with the Füh carrying track 28 are locked, which are the two bows 36A and 36B assigned windows offset in vehicle vertical direction to each other. So there is a height coding with respect to the locking stones 48 the crossbar 36A and 36B in front. Alternatively, an encoding could be in terms of the dimensions of the locking blocks 54 and the associated Riegelausnehmungen the guide rail and the slider plate may be provided.

Alternatively to a locking block of the type described above, a pivotable on the Spriegelgleitern 38A and 38B stored latch element can be used. The function does not change here. Rather, it then corresponds to the above for the embodiment of the 1 to 11 described function.

In the 12 to 15 is shown in a highly schematic way an alternative embodiment of a folding roof mechanism for a controlled wrinkling.

Unlike the embodiment of the 1 to 11 is here on a slider plate 24 ' a rooftop projecting in the vehicle rear direction actuating finger 60 formed, on its underside a recess 62 having.

When moving the slider plate 24 ' in the vehicle rear direction starting from the in 12 the position shown moves the finger 60 on one at a bowing glider 38A ' pivotally mounted latch rocker 64A on that over a first thigh 66 , which at its end a tab 68 has, in a locking recess 70 a guide rail 28 ' is locked. By driving up the actuating finger 60 on the second leg 72 the latch rocker 64A the latter is pivoted so that the tab 68 on the latch recess 70A the guide rail 28 ' is pivoted and the tab 68 in the lower-side recess 62 of the finger 60 the slider plate 24 ' intervenes. The finger 60 So acts as an actuator for the latch rocker 64A , This will make the bowing glider 38A ' from the guide rail 28 ' unlocked and with the slider plate 24 ' locked. The resulting position is 13 refer to.

In another method of now from the slider plate 24 ' and the bowing glider 38B ' existing slider package in the direction of the vehicle rear moves an actuating finger 74 of the second leg 72 the latch rocker 64A on a latch rocker 64B a rear glide glider 38B ' a rear-side crossbar on ( 14 and 15 ). According to the unlocking and locking of the latch rocker 64A of the latch glider 38A ' This is the latch rocker 64B pivoted, leaving a tab 68 from a bar recess 70B the guide rail 28 ' exit and into a lower-side recess 78 of the actuating finger 74 the latch rocker 64A intervenes.

In the embodiment described above according to the 12 to 15 the order of decoupling and coupling is automatically maintained because locking to the guide rail 28 ' of the front crossbar 38A only possible after the rear, guided crossbeam 36B already on the guide rail 28 ' locked and from the bowing glider 38A ' was decoupled.

In the inventively designed folding roof mechanism is found by the successive unlocking and locking the crossbar relative to the guide rail 28 respectively. 28 ' on the one hand and the slider plate 24 or the slider plate 24 ' and bow-shaped bowing gliders 38A ' on the other hand, a regulated wrinkling by issuing the Ausstellspriegel 42A and 42B instead of. After each unlocking step, only one is placed on the fabric blank 14 apprentice fold in motion. This also flutter noise can be reduced, which occur on the fabric blank. In the embodiments described above, furthermore, a four-bar mechanism is used for the rooftop, which allows high clamping forces, at the same time a controlled wrinkling can be realized without a closed mechanical chain between the rooftop and the crossbeams would be required.
