Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is guided slidably in a longitudinal direction of a vehicle and is vertically movable in a range of a rear edge of a cover, and selectively closes or at least partially releases a roof opening of a fixed roof surface. And a sliding device that slides the cover, at least one height adjusting device that adjusts the height of the trailing edge of the cover, and a sliding device that uses a drive cable that is guided not to expand and contract. And a common drive for actuating the height adjustment device.

2. Description of the Related Art In the case of a known vehicle roof of this type (German Patent No. 2942006), a screw telescopic lock which is supported by a housing fixed to the roof and acts on both sides of the cover in order to adjust the height of the cover. A member is provided. For inserting and withdrawing the screw telescopic member,
This is done by the engagement between the drive pinion of the screw telescopic member and two drive cables configured as screw cables. Each of the two threaded cables, on the side of the cover which actuates the telescopic jack, cooperates via a drive member fixed to the cable with a coupling member of the slider hingedly attached to the front of the cover. After raising the cover to the ventilation position, the screw is constructed only on a part of the length of the screw cable so that the drive connection between the screw cable and the telescopic jack is broken. In this case, the drive member is
To slide the raised cover to the open position, drive the front slider on the same roof side. Thus, couplings and uncouplings alternate between the drive cable and the sliding or height adjustment device.

The known vehicle roof is
It requires a mechanism that is relatively expensive, complicated, and thus prone to failure. The object of the invention is to create a vehicle roof which can be operated with a simple and therefore robust mechanism.

[0004]

This object is based on the invention, starting from a vehicle roof of the type mentioned at the outset,
The height adjustment device is pivotally supported on a slider that can be driven in the vehicle longitudinal direction by a drive cable and that performs a longitudinal adjustment movement of the vehicle against the adjustment movement of the sliding device when the cover slides. Will be solved. That is, the present invention is applied to the vehicle longitudinal direction.

Further embodiments of the invention are shown in the dependent claims. In the case of the vehicle roof according to the invention, it is basically conceivable, for example, to drive the cover via only one sliding device and only one height adjusting device, but with a common drive device in the opposite direction. A sliding device and a height adjusting device, which can be adjusted in opposite directions in the longitudinal direction of the vehicle via two drive cables actuated to each other, preferably act on both sides of the cover.

In a manner known per se, it is advantageous if the cover is arranged flush with the peripheral part of the roof surface in the closed position, each sliding device driving the front region of the cover and the vehicle longitudinal direction. A slider that is movably guided to. In this case, the slider of the sliding device and the slider of the height adjusting device are always connected to the end of the drive cable in question. The vehicle roof can be configured such that in the case of a so-called spoiler roof the cover is slid backwards above the fixed roof surface and in the case of a sliding roof the cover is slid backwards below the fixed roof surface. Therefore, the height adjuster must raise or lower the trailing edge of the cover during the transition from the closed position to the open position.

The sliders of the sliding device and the height adjusting device can run along a longitudinal guide which is lower than the roof surface, and the height adjusting devices are each mounted on the slider and above the fixed roof surface. A vehicle roof construction characterized in that it has an elevating lever for raising the cover in a ventilation position in which the rear edge of the cover is raised is particularly advantageous. In this case, especially when sliding the cover in the direction from the ventilation position to the open position, the lifting lever is disengaged from the cover and a rear cover guiding element installed in the rear area of the cover is provided above the fixed roof surface. Is engaged with the rear longitudinal guide,
Preferably, the rear cover guide element is disengaged from the rear longitudinal guide and the lift lever is coupled to the cover when the cover is moved from the open position to the ventilation position. In the case of this type of vehicle roof, the roof opening portion exposed at the cover open position can be held particularly large despite the simple structure.

[0008]

The function of the illustrated tilt slide roof will be described below. In the position shown in FIGS. 2 and 5, the cover 12
Closes the roof opening 11, in this case flush with the peripheral part of the fixed roof surface 10. Sliders 15 and 16
Are at the front end position and the rear end position, respectively (FIG. 4). In this case, the connecting pin 19 fixed to the front cover supporting member 20 is connected to the front lower end of the front portion 24 of the guide path 21 and the rear end of the connecting slit 18 of the elevating connecting mechanism 17 connected to the screw cables 43 and 42. Located in. The elevating lever 26 is pivoted counterclockwise to the end position, and at this end position, the connecting pin 30 is located at the rear lower end of the guide path 31, and the cervical shaft 27 of the connecting slit 29 of the connecting mechanism 28 fixed to the cover. Located at the rear end. Thus, the cover 12
It is ensured that neither anterior nor posterior favorable effects occur.

When the cover 12 is opened, the drive pinion 41 is driven by the electric motor 39 in the direction of the arrow in FIG.
Thus, the front slider 15 is slid backwards, while
At the same time, the rear slider 16 is pulled forward. The horizontal rear part of the connecting slit 18 cooperates with the forwardly descending part 24 of the guideway 21 to hold the cover 12 in the front end position, while the front slider 15 is free with respect to the connecting pin 19. Do exercise. At the same time, by the relative movement of the slider 16 with respect to the guide path 31 fixed to the roof, the connecting pin 30
Rises in the rear end of the guideway 31 that rises forward, thus raising and lowering lever 26 is pivoted clockwise and trailing edge 32 of cover 12 is raised above fixed roof surface 10. When the forwardly rising front part of the lifting and lowering connecting mechanism 17 coincides with the forwardly descending front end part 24 of the guide path 21, the cover 12 is released for the backward sliding movement. The connecting pin 19 rises along the front upper end 24 of the guide path 21,
The front slider 15 is brought into contact with the upper front end of the connecting slit 18.
Drive-coupled with. In this case, the cover is raised forward and rearward to move away from the edge gap packing 46 (shown only in FIG. 7). Thus, when the cover 12 reaches the ventilation position shown in FIG. 6, the cover 12 is retracted above the fixed roof surface 10 by driving the slider 15. In this case, the connecting pin 19 is moved rearward along the main portion 23 of the guideway 21. At the same time, the connecting pin 30 moves forward along the relatively high horizontal part of the guideway 31. During this movement, the cover 12 firstly engages with the engagement of the cervical shaft 27.
The connecting slit 29 of the connecting mechanism 28 fixed to the cover
Will be guided inside. After a slight displacement, the elevating lever 26 is disengaged from the cover 12 as the cervical shaft 27 emerges from the forwardly open end of the connecting slit 29. On the other hand, the rear cover guide element 34 is introduced into a guide channel 36 which opens forward of a guide rail 37 fixed to the roof. The cover is thus reliably guided in the front and rear areas of the cover, even when translated further rearward. The sliders 15, 16 pass in sequence, so that the front slider 15 can be driven to the extent of the rear edge of the roof opening 11 without being obstructed by the rear slider 16. Therefore, the roof opening 11 can be released almost completely without the displacement mechanism being disturbed by the roof reinforcing member (for example, the lateral hoop 38). Guideway 36
Directly contacts the fixed roof surface 10 from above, and the guideway 2
1 gradually rises rearward, so that the rising angle of the cover slid rearward is kept relatively small, and therefore,
Undesirable noise generation is suppressed.

When the cover is closed, the above-mentioned movement process proceeds in the opposite direction. The cover 12 is driven forward by the front slider 15. The rear slider 16 is
Traveling backwards, the elevating lever 26 is placed at a position where the neck shaft 27 can be introduced into the connecting slit 29 by the cooperation of the connecting pin 30 and the guide passage 31, while the rear guide element 34 is
Exit from guideway 36.

In the above-described embodiment, the lifting connection mechanism 17 is used.
Is connected to the front slider 15, but instead a corresponding lifting connection can be installed on the cover 12, in particular on the front cover support member 20 or parts thereof. In this case, the connecting slit corresponding to the connecting slit 18 is provided with a rearward descending portion. In the case of this modification, the opening width can be further increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below in detail with reference to the drawings. 1, the fixed roof surface 10
Fig. 1 shows a vehicle roof in which two roof openings are sequentially arranged in the vehicle longitudinal direction at intervals. Both roof openings can be selectively closed or at least partially open by means of the cover 12. The front cover 12 is shown in the closed position, while the rear cover 12 is shown.
Are shown in a partially open state. The drive and adjusting device is constructed identically for both covers 12, and therefore only the front cover will be described below. Both covers 12 can be moved independently of each other. For example, in the case of a motorized cover drive, each cover can be provided with its own actuating switch. In the closed position (FIG. 1, front cover; FIGS. 2, 5), the cover 12 is flush with the peripheral edge of the roof surface 10 (flash glazing). The roof opening 11 is located below the fixed roof surface 10 and is surrounded by a roof frame 13 forming front longitudinal guides 14 on either side of the roof opening. A front slider 15 and a rear slider 16 are slidably guided along the front longitudinal guide 14 on each side of the roof. In the case of the illustrated embodiment, the front slider 15 is provided with an elevating and lowering connecting mechanism 17 having a connecting slit for raising the front portion obliquely forward (FIGS. 5 and 6). The connecting pin 19 protruding laterally from the front cover supporting member 20 provided on the lower surface of the cover 12 engages with the connecting slit 18 of the elevating connecting mechanism 17. The free end of the connecting pin 19 projects into the guide path 21 of the connecting mechanism 22 which also extends along the side edge of the roof opening 11. Guideway 21
Has a main portion that extends at least approximately parallel to the front longitudinal guide 14 and transitions at the front to a downwardly descending portion 24. The main portion 23 of the guideway 21 gently rises from the front to the rear. Thus, with the cover open,
Wind noise is suppressed low.

An elevating lever 26 is attached to the rear slider 16. In the case of the embodiment of FIGS. 5 and 6, the lifting lever faces forward from the slider 16. Lifting lever 26
A neck shaft 27 protruding laterally is provided at the other end of the. The cervical shaft 27 forms a coupling element for releasably coupling the lifting lever 26 in the rear region of the cover 12, so that the coupling mechanism 28 is fixed to the lower surface of the region. The connecting mechanism 28 has a connecting slit 29 which is parallel to the roof plane and opens forward like a funnel. A connecting pin 30 is provided in the central area of the elevating lever 26 and projects laterally to pivot the elevating lever 26 in cooperation with another guide path 31 of the connecting mechanism 22. Near the rear edge 32 of the cover 12, rear cover support members 33 are provided on both sides of the cover, and a cervical rear cover guide element 34 projects laterally from the support member.

Each rear cover guide element 34 has a guide path 3 which opens forward in a funnel-like manner on the guide rail 37 when the cover is pulled back.
Work with 6. Both guide rails 37 rest on the fixed roof surface 10 and extend rearward in the vehicle longitudinal direction from the rear edge of the roof opening 11. The lateral hoop provided below the fixed roof surface 10 is indicated at 38. For driving the tilt slide roof, an electric motor 39 provided with a transmission device 40 for driving a drive pinion 41 and installed in the center of the front of the roof opening 11 below the roof surface 10 is used. Drive pinion 41
Are two screw cables 42, which are guided so that they do not expand and contract,
Mesh with 43. In FIG. 7, the guide channels of the screw cables 42 and 43 are indicated by 44 and 45. Screw cable 42,
A front slider 15 is drivingly coupled to one end of each 43. The other ends of the screw cables 42, 43 are connected to the rear slider 16 on the other side of the roof opening 11 (FIG. 4).

[0015]

With the roof construction according to the invention, the adjustment movement of the drive cable on the cable exit side, which is not used in the known arrangements, can be used for actuation of the height adjustment device.
Therefore, it is possible to use a drive cable having a uniform property over the entire length. When using a threaded cable, it is only necessary to provide a screw on the cable part, and not on the intermediate cable part.
