DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

[0037] The drawing shows a motor vehicle 10 having a vehicle roof 12 provided with a roof opening system 14. For this purpose, vehicle roof 12 has a solid roof portion 16 which comprises a rear transverse element 18, a front transverse element 20, which forms a front header of motor vehicle 10, and two longitudinal beams 22A and 22B. Solid roof portion 16 encloses a roof opening 24 which can be selectively closed or at least partially opened by two roof panels 26 and 28, which are part of roof opening system 14. In particular, vehicle roof 12 can be configured by roof opening system 14 in such a manner that roof opening 24 is covered or closed by both roof panels 26 and 28 (FIG. 1), which corresponds to a closed position, or that roof opening 24 is partially opened by detaching roof panel 26 from solid roof portion 16 and retaining roof panel 28 on solid roof portion 16, which corresponds to a first open position (FIG. 2), or that both roof panels 26 and 28 are detached from solid roof portion 16 and roof opening 24 is completely open, which corresponds to a second open position (FIG. 3).

[0038] In addition to the two roof panels 26 and 28, roof opening system 14 has two guide rails 30A and 30B which extend along the lateral edges of roof opening 24 on either side of a vertical longitudinal center plane of the roof, and two lock slides 32A and 32B which are guided in guide rails 30A and 30B in a sliding manner. Lock slides 32A and 32B are each driven, via a drive cable arrangement 34A and 34B, respectively, by a shared drive motor 36, which is an electric motor and which is accommodated by transverse element 18 of solid roof portion 16. For driving drive cable arrangements 34A and 34B, drive motor 36 has a drive pinion which is engaged with the drive cables of drive cable arrangements 34A and 34B. The drive cables can be helix cables or flexible gear racks.

[0039] A frame 38 is provided to retain lock slides 32A and 32B in guide rails 30A and 30B, frame 38 being attached to the vehicle body and being rigidly connected to solid roof portion 16 or being part of solid roof portion 16. On its upper side, frame 38 has a circumferential sealing element 40 which interacts with the undersides of roof panels 26 and 28 when they are in the closed position. Furthermore, the rear roof panel has, on its front edge, a seal 42 which interacts with the rear edge of front roof panel 26 in the closed position.

[0040] In its rear edge portion in the middle of the vehicle, rear roof panel 28 has a securing bracket 44 which, as can be seen in FIG. 10, in particular, engages under a corresponding retaining section 46 formed integrally on frame 38 and thus formed on solid roof portion 16. Correspondingly, front roof panel 26 has, in its front edge portion on the underside in the middle of the vehicle, a retaining bracket 48 which engages under a retaining section 50 also formed on the solid roof portion 16 and formed by frame 38.

[0041] Additionally, each of the two roof panels 26 and 28 has, at its underside, two grip inserts 52 which facilitate manual mounting and dismounting of roof panels 26 and 28 on solid roof portion 16.

[0042] To be able to secure roof panels 26 and 28 to solid roof portion 16, roof panels 26 and 28 have, on their undersides on either side of the vertical longitudinal center plane of the roof, two locking pins 54 which each have a constriction 56.

[0043] Lock slides 32A and 32B, which are guided in guide rails 30A and 30B and each provided with eight runner elements 58, each have four keyhole-shaped recesses 60A, 60B, 60C and 60D on their upper side, the two recesses 60A and 60B interacting with locking pins 54 of front roof panel 26 and the two recesses 60C and 60D interacting with the locking pins of rear roof panel 28. In the longitudinal direction of lock slides 32A and 32B, recesses 60A, 60B, 60C and 60D each have a wide unlocking section, to which a narrow locking section is continuous. When the respective locking pins are located in the wide unlocking sections, respective locking pin 54 can be pulled out of the respective recess. When locking pins 54 engage the narrow locking sections, the respective edge portions of recesses 60A, 60B, 60C and 60D are accommodated in constrictions 56, locking pins 54 thus being secured against becoming detached from respective lock slides 32A and 32B.

[0044] In the longitudinal direction of respective lock slides 32A and 32B, the locking sections of the two front recesses 60A and 60B are shorter than the locking sections of the two rear recesses 60C and 60D. This means that, starting from the locking position, which is illustrated in FIG. 16, for example, lock slide 32A can first be displaced by a specific length of travel so that the locking pins of front roof panel 26 are located in the wide unlocking sections of front recesses 60A and 60B and front roof panel 26 can be detached from solid roof portion 16, whereas locking pins 54 of rear roof panel 28 continue to be located in the narrow locking sections of the two recesses 60C and 60D, which means that rear roof panel 28 continues to be secured to solid roof portion 16. In this way, the first open position, which is illustrated in FIG. 2, can be realized. When front roof panel 26 is removed, lock slides 32A and 32B can be displaced further so that locking pins 54 of rear roof panel 28 are also located in the unlocking sections of associated recesses 60C and 60D and rear roof panel 28 can be removed from solid roof portion 16, as well. In this way, the second open position, which is illustrated in FIG. 3, can be realized.

[0045] For locking pins 54 to be able to interact with lock slides 32A and 32B, frame 38 has four cutouts 62 on either side of the vertical longitudinal center plane of the roof, which can be engaged by locking pins 54.

[0046] Each of the runner elements 58 of lock slides 30A and 30B has an elastic bow 59 on top, allowing lock slides 30A and 30B to be guided in guide rails 30A and 30B without rattling.
