BACKGROUND OF THE INVENTION The present invention comprises two covers which, in the closed position, are arranged one behind the other and which selectively close or at least partially open the roof opening of the fixed roof surface, and which are provided below the covers. The present invention relates to a vehicle roof having two sliding canopies movably guided in the longitudinal direction of the vehicle.

2. Description of the Related Art In the case of a known vehicle roof of this type, for example, in the case of Japanese Patent Laid-Open No. 1-202521, two guide paths extending in the longitudinal direction of the vehicle are provided on each side of the roof in order to guide both sliding canopies. one of which receives a sliding member projecting laterally from one sliding canopy, while another guideway receives a sliding member projecting laterally from another sliding canopy. The members engage. In this case, the sliding canopy is in different height positions, both in the closed position and in any other position, so that it can be slid up and down during pure translational movements.

0003

In the case of the known vehicle roofs, the sliding canopy of the vehicle as a whole appears stepped vertically from the interior of the vehicle and is therefore often unsatisfactory in terms of aesthetic impression. The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a sliding canopy with a particularly favorable appearance even when closed, and to provide a complicated operating mechanism for the sliding canopy. The goal is to create a vehicle roof that is not needed.

0004

[Means for Solving the Problems] In order to achieve the above object, the present invention takes the following technical measures. That is, two covers are arranged one after the other in the closed position and selectively close or at least partially open the roof opening of the fixed roof surface, and the cover is arranged below the covers and is movably guided in the longitudinal direction of the vehicle. In a vehicle roof having two sliding canopies, both sliding canopies, in the closed position, are at least approximately the same height and are separated from each other in the longitudinal direction of the vehicle by an immovable transverse web; guiding the sliding canopy above the rear sliding canopy in the closed position when the front sliding canopy slides, and guiding the sliding canopy above the rear sliding canopy in the closed position when the rear sliding canopy slides; The present invention is characterized in that a cam surface is provided that guides the slide canopy above the front slide canopy in the closed position when the rear slide canopy slides.

[0005]

With the vehicle roof according to the invention, an unattractive tiering of the vehicle canopy in the closed position of both sliding canopies is avoided. The manufacturing and installation costs of the functional components that help move the sliding canopy are fairly low. It is also advantageous to design the vehicle roof in such a way that a sliding canopy that has been swiveled upwards rests on another sliding canopy in the closed position when it is slid further. It is expedient for the sliding canopy to be provided on each side with a laterally projecting sliding member which cooperates with a common guide on each side of the roof. A particularly simple construction is obtained if the two guides are constructed in such a way that they receive in a common guideway the sliding members of the sliding canopies which are slid overlappingly. In this case, both guides
It is expedient to each have an upper, inwardly inclined side guide surface which is laterally abutted by the sliding member of the sliding canopy.

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. 1 to 7 show embodiments of the present invention, in which FIG. 1 is a plan view of a vehicle roof according to the present invention, FIGS. 2 to 6 are longitudinal sectional views of the vehicle roof of FIG. 1 in various cover positions, FIG. 7 is a cross-sectional view along the line VII-VII of FIG. 6a.

The vehicle roof in the closed position shown in FIG. 1 has a cover 10 that projects forward when the roof is closed, and a cover 11 that is placed immediately behind and at the same height as the cover 10 when the roof is closed. In the position of FIG. 1, both covers 10, 11 close a continuous roof opening 12 formed in the fixed roof surface. In the embodiment shown, the front cover 10 is constructed as a ventilation cover which is operatively connected on both sides with an operating mechanism with front and rear height adjustment devices 14, 15. The concepts "front" and "rear" relate to the forward direction of the vehicle incorporating the roof. The above-mentioned vehicle roof, including the operating mechanism, is constructed essentially mirror-symmetrically with respect to the longitudinal axis of symmetry.

For the movement of the cover 10, a drive 16 is provided which includes two drive cables 17, which are driven by a drive motor 18 via a transmission 19. A manual crank or the like may be provided instead of the drive motor 18 and transmission 19. The transmission 19 has, on the output side,
It has a pinion drivingly coupled to both drive cables 17. On both sides of the roof opening 12 extends a continuous longitudinal guide 20 (for example a guide rail or part of a roof frame 21 fixed to the roof). Each longitudinal guide 20 has a cable guiding channel 22 for the drive cable 17 arranged on each side of the roof and a slideway 23 open towards the roof opening 12 .

The height adjustment devices 14, 15 are actuated independently of each other by virtue of the displacement movement of the drive cable 17 and can be constructed in the manner described in German patent application P 39 16 905.7. The front height adjustment device 14 has a freely operable swiveling lever 24 whose front end region is pivoted for rotational movement about a stationary shaft 25 extending at right angles to the direction of cover sliding.
is included. A rearwardly rising connecting passage 26 extends in the longitudinal direction of the pivot lever 24. Engaged in the connection channel 26 is a connection tenon 27, which is a part of a drive member 28 connected to the drive cable 17 and which carries out a longitudinal movement together with said drive member.

In the region of the rear end of the pivot lever 24, the connecting channel 26 transitions into a fork-shaped guide channel 29 which is open to the rear. Attached to the cover 10 or to a member 30 fixed to the cover (for example a cover frame) is a sliding element 31 which is introduced into the guide channel 29 when the cover 10 assumes its front end position (see FIG. 2). Thus, guide route 29
and the sliding element 31 serves to removably connect the front height adjustment device 14 and the cover 10.

The attached cover support 33 connects the bolt 32 to the drive member 28 via a rod 34. The slideway 23 is connected via a rod 36 to a cover support 33 and thus a drive member 28 and a drive cable 1
A locking member 35, which is also coupled to 7, is slidably guided in the vertical direction. Behind the locking member 35, there is a sliding path 2.
3 is located a sliding member 37, which is likewise displaceable in the longitudinal direction, on which a short lifting lever 38 of the rear height adjustment device 15 is mounted for a pivoting movement about a horizontal axis 39.
The lower end (viewed in the cover closed position) is pivoted.

The member 30 fixed to the cover is connected via a hinge bolt 40 to the other end of the lifting lever 38, which is located above when viewed in the cover closed position. The hinge bolt has
A roller 41 is rotatably supported. Lifting lever 3
8 is fitted with a further roller 42 which is arranged rearwardly offset with respect to roller 41 in the cover closed position. On the longitudinal guide 20 is carried a connecting member 43 having two connecting slots 44, 45, which cooperate with rollers 41 and 42, respectively, and is fixed to the roof.

A cover 10 is provided at the front of the connecting member 43.
When the sliding member 37 is at the front end position, the through hole of the sliding member 37 is formed with an opening that receives the upper part of the locking mechanism 46 that is guided so as to be movable perpendicularly to the sliding direction of the sliding member. In the position shown in FIGS. 2a and 2b, the locking member 35
A securing channel 47 configured to slide beneath the locking mechanism 46 holds said locking mechanism in engagement with the coupling member 43 . The locking member 35 has the following functions: when the locking member 35 is slid rearward (Fig. 3a, Fig. 3b, Fig. 4a, Fig. 4b
(See) A recess 48 is formed that is open upward and can receive the lower part of the locking mechanism 46.

Below the front cover, there is a front sliding canopy 50 that is coupled to and driven by the cover 10 via a coupling lever 51 that acts near the front end of the cover when the cover slides.
is provided as a cover lining. In the closed position of the cover 10, the sliding canopy 50 covers the front frame opening 52, which is defined by the roof frame 21 and the immovable transverse web 53.

The slide cover 11 that protrudes rearward when the vehicle roof is closed is supported by front and rear cover support members 54 and 55.
Supported by The cover supports 54, 55 are slidably guided via sliding shoes 56 along continuous longitudinal guides 57 which extend laterally of the roof opening. The longitudinal guide 57 can be constructed as a separate guide rail corresponding to the embodiment shown in FIG.

However, the longitudinal guide 57 can also be integrally connected to the longitudinal guide 20. cover 1
1, a drive electric motor 59, a rear transmission 6
A drive device 58 is provided which includes two drive cables 61 guided so as not to extend or retract. Drive cable 6
1 is drive-coupled with at least one cover support member 54, 55 on the corresponding cover side, as shown in FIG.

A sliding canopy 62 is provided below the cover 11 and serves as a cover lining. The sliding canopy 62 is coupled to the cover 11 via a drive member 63 that acts on the cover 11 and the rear end of the canopy, and follows the sliding movement of the cover 11. In the closed position of the cover 11, the sliding canopy 62 opens into a rear frame opening 64 defined by the roof frame 21 and the transverse webs 53.
to cover.

[0018] The slide canopies 50, 62 have on both sides,
A laterally projecting sliding member, preferably in the form of a sliding shoe 65, is connected via an elastic holder 66 (see FIG. 7). There are sliding canopies 50, 62 on both sides of the roof.
A common continuous guide 67 extends therethrough. In the illustrated embodiment, the guide 67 is integrally connected to the roof frame 21 and is connected to the roof opening 1 of the lateral water channel 68.
Form an interface facing 2. Each guide 67 forms a common guideway 69 that receives the sliding shoes 65 of both sliding canopies 50, 62. In this case, the guide 67 is the slide canopy 50, 62
The sliding shoe 65 has a side guide surface 70 that slopes inwardly and upwardly and comes into contact with the slide shoe 65 from the side.

When both covers 10, 11 are in the closed position (see FIGS. 2a and 2b), the sliding shoes 69 of both sliding canopies 50, 62 are supported by the lower sliding surface 71 of the guideway 65. . In this case, both sliding canopies 50, 62 arranged one behind the other are at least approximately at the same height. The front and rear edges of the sliding canopies 50 and 62 are connected to the roof frame 21 or the roof frame 21.
It is supported by a fixed roof canopy 72 and lateral webs 53 that cover from below.

When the pivoting lever 24 is swiveled up into the position shown in FIG. It is raised to a position where it is at least substantially flush with the front edge of the roof opening 12. at the same time,
Lifting lever 38 is in an essentially vertical position (see Figure 2b)
The hinge bolts 40 position the cover so that the rear edge 74 of the cover 10 is at least substantially flush with the front edge 75 of the rear cover 11. The locking mechanism 46 engages in a recess in the front end of the connecting member 43 fixed to the roof, thus ensuring that the sliding member 37 is not displaced relative to the member fixed to the roof. The securing path 47 prevents the locking mechanism 46 from accidentally coming off the recess of the connecting member 43.

The ventilation cover 10 is moved from the closed position to the ventilation position (
3a), the drive end of the drive cable 17 is moved rearward by the drive motor 18. In this case, the connecting tenon 27 is moved rearwardly by the drive member 28 along the part of the connecting path 26 that extends parallel to the slide path 23 in the pivot lever position, while the connecting tenon 27 is moved rearwardly by the drive member 28 via the rod 34. The coupled cover support 33 releases the pivoting lever 24 for a pivoting movement in the clockwise direction (see FIG. 2a).

Next, when the connecting tenon 27 moves along the rearwardly rising portion of the connecting path 26, the pivoting lever 24 is pivoted clockwise (see FIG. 2a);
It is lowered from the position shown in a to the pivoted position of FIG. 3a. In this case, the pivoting lever 24 drives the sliding element 31 downwards, which enters the sliding path 23 via the opening 76 in the upper boundary wall 77 of the sliding path 23 . Due to the pivoting movement of the pivoting lever 24, the cover 10 moves from the closed position of FIG. 2a to the pivoting position of FIG. Swiveled into ventilation position. The interior of the vehicle is ventilated via ventilation openings 78 in front of the sliding canopy 50 in the closed position. The front sliding canopy 50 has a coupling lever 51
, but it also completely covers the front frame opening 52 .

Further displacement of the drive cable 17 to the rear causes the sliding element 31 to disengage from the pivot lever 24. The locking mechanism 46 is released from the connecting member 43 and the locking member 3
5, the sliding member 37 is thus introduced into the recess 48 of
Drivenly coupled to drive cable 17 . The locking member 35 and the sliding member 37 are simultaneously moved rearward. The engagement between the roller 41 and the connecting slit 44 causes the lifting lever 38 pivotally connected to the sliding member 37 to move counterclockwise (see FIG.
(see Figures 3b and 4b).

The lifting lever 38 is pivoted to the position of FIG. 4b. The region of the trailing edge 74 of the cover 10 is thus lowered and the roller 41 passes from the coupling slit 44 into the slideway 23. During the course of said movement, the cover 10 is pivoted around the sliding element 31 guided in the slideway 23 with a rearward displacement relative to the front edge 73 of the cover. The front edge 73 of the cover 10 is therefore raised to some extent, as can be seen by comparing Figures 3a and 4a. The sliding canopy 50 is further slid rearward slightly, covering the front frame opening 52 and similarly aligned with the rear sliding canopy 62.

Starting from the intermediate position in FIG. 4a, the front cover 10 is moved rearwardly parallel to the fixed roof surface 13 and the rear cover 1
1 can be slid downward. In this case, the rear edge 79 of the sliding canopy 50 driven by the cover 10 has a front cam surface 80 inclined upwardly behind the transverse web 53.
Published in The cam surface 80 guides the sliding canopy 50 above the rear sliding canopy 62 in the closed position when the sliding canopy 50 is raised and the cover 10 and the sliding canopy 50 are slid further rearward (see FIG. 5b). The front frame opening 52 and the roof opening front above it are opened (see FIG. 5a).

When the driving direction of the driving cable 17 is reversed, the cover 10 and the sliding canopy 50 are slid forward again until the roller 42 hits the connecting slit 45. When the sliding member 37 is moved further forward, the lifting lever 3 is moved by the cooperative action of the roller 42 and the connecting slit 45.
8 is raised and the cover 10 is raised. The process described above proceeds similarly in the opposite direction.

However, starting from the intermediate position of FIGS. 4a, 4b, the rear cover (sliding cover) 11 can also be moved forward. In this case, the front edge 81 of the rear sliding canopy 62 driven by the cover 11 hits the rear cam surface 82 of the transverse web 53 that rises forward and upward. The sliding canopy 62 is guided upward in cooperation with the cam surface 82, and when the cover 11 is moved further forward, it is placed above the upper sliding canopy 50 in the closed position (
(see Figure 6a). In this case, the rear frame opening 64 and the rear part of the roof opening 12 above it are open.

Of course, the above-described configuration and guidance of the sliding canopies 50, 62 is not limited to the above-described combined use of ventilation covers and sliding covers. For example, the rear cover can also be configured as a ventilation cover by disposing an operation mechanism corresponding to the operation mechanism of the ventilation cover 10. Furthermore, the front cover is configured as a slide cover,
The rear cover can also be configured as a ventilation cover. Furthermore, for one or both covers, the rear end of said cover is fixed to the fixed roof surface 13 in the manner of a sliding tilt roof.
An operating mechanism may be provided which raises the device upwardly.

[0029]

[Effects of the Invention] As mentioned above, the vehicle roof of the present invention has the following features:
a rear sliding canopy with both sliding canopies placed at least approximately at the same height in the closed position and separated from each other in the longitudinal direction of the vehicle by an immovable transverse web such that said canopy is in the closed position when the front sliding canopy is slid; lead upwards,
Since the transverse webs are provided with cam surfaces that guide said canopy above the front sliding canopy in the closed position when the rear sliding canopy is slid, the sliding canopy also has a particularly pleasing appearance when closed; Because of the sliding canopy, it was possible to create a vehicle roof that does not require a complicated operating mechanism.
