This application is a U.S. Utility which claims the benefit of the priority from European Application 13 001 071.3, filed Mar. 4, 2013, the entire disclosure of which is incorporated herein by reference in its entirety.
The invention relates to a vehicle sliding roof device with a cover unit that comprises a cover and a cover frame and that is shiftably supported on guides of the sliding roof device by a support device and that can be adjusted between a closed position covering a roof opening and at least one open position.
A vehicle sliding roof device is known from DE 32 23 750 C2 whose sliding roof cover can be extended from a roof opening and also be lowered below a roof surface adjacent to the rear. The cover comprises a cover frame permanently connected to the cover and comprises lateral orifices that contain an extending- and lowering mechanism by which the cover can be extended and lowered on its rear edge in order to free the roof opening
The invention is based on the problem of creating an initially cited vehicle sliding roof device that is improved as regards the freeing of a roof opening.
This problem is solved in accordance with the invention for the initially cited vehicle sliding roof device in that the cover is detachably attached on the cover frame, that is shiftably supported on the guides and can be removed for freeing a roof opening of the cover frame arranged in particular in the closed position.
Therefore, in the case of the vehicle sliding roof device in accordance with the invention a cover frame opening or roof opening can be freed by removing the cover from the cover frame in a simple manner. This is possible in that the cover unit is supported exclusively on the cover frame and that a connection of the cover with the cover frame is formed in such a manner that the cover can be removed in particular without tools or auxiliary aids in a simple and rapid manner.
Whereas in the case of customary sliding roofs that are manually operated or shifted the cover unit comprises a handle or the like in the area of the front edge of the cover unit whose movement path during the pushing on of the cover unit is usually limited by a roof structural component adjacent at the rear, as a result of which a maximal opening position and a size of the roof opening that can be freed is limited, in the case of an entirely removed cover the entire opening surface inside the cover frame can be freed.
It can basically be provided that the cover can be removed in every position of the cover frame, for example, when the cover unit is a part of a sliding roof guided on the outside and is shifted during opening over the roof component adjacent at the rear. However, the cover frame is advantageously arranged in its closed position when removing the cover so that the freed cover frame opening coincides substantially with the roof opening of the sliding roof device that can be freed and in particular no front frame part of the cover frame extends through the roof opening.
The cover frame can be constructed in a circumferential manner or it is present only on the sides required for the support. The cover frame must have a strength and rigidity that together with the attached cover make the strength necessary for the entire cover unit available. If the cover has been removed and the cover frame is advantageously at rest and not shifted, a lesser intrinsic strength is already sufficient.
The cover is advantageously detachably attached to the cover frame by a holding device. The holding device is, e.g., a plug holder with, e.g., four plug parts or a suspension device with hook elements or the like. In any case the holding device is simple to operate if the cover is removed and if it is reattached. The holding device can also comprise an arresting device for holding the cover with an arresting force on the cover frame.
A preferred design provides that the cover can be locked by a bolting device on the cover frame. The bolting device makes available a reliable fixing of the cover on the cover frame, that is actuated in particular only from the vehicle cabin, so that the cover cannot be removed by third parties from the outside.
The bolting device advantageously contains at least one bolt part that is movably supported on the cover frame and that can be locked by a cover engagement part arranged on the cover. Therefore, a locking with few structural parts is possible in a direct bolt engagement.
According to an especially preferred embodiment it is provided that the bolt part can be adjusted between a first bolting position in which it locks the cover on the cover frame and a second bolting position in which it frees the cover for removal from the cover frame and in particular locks the cover frame on a sliding roof frame. The two bolting positions make possible an operationally reliable actuation. As a result of the fact that the cover frame is locked before the removal of the cover on a sliding roof frame or basically on a structural component fixed to the roof, the cover frame is always secured against shifting, even if a locking device or an arresting device of the cover unit is not arranged in its closing, bolting or arresting position.
The bolting part advantageously contains a bolt hook for one or the first bolting position and a bolt hook for one or the second bolting position. The bolting part can be supported pivotably or also shiftably in order to carry out its bolting movements. The bolting device or the bolting part can be operated manually, whereby a part of the bolting device or the bolting part can be directly adjusted or also indirectly, for example, by another operating part or by a tool.
The bolting device can be arranged on the front edge of the cover unit or on the front transverse part of the cover frame but is not limited to this arrangement. Thus, the bolting device or the at least one bolting part can also be arranged on a lateral longitudinal part of the cover frame.
A preferred design provides that the cover unit can be manually shifted by an actuation device arranged in particular on the cover. Basically, a removable cover can also be provided in the case of a sliding roof device with a motor-driven cover unit. But the manual shifting of the cover unit makes a simple and economical construction possible. If during the removal of the cover the manual actuation device is also removed, when the cover frame opening is free the vehicle cabin in the area of the roof opening is free of such parts of the actuation device.
It is especially preferred if the actuation device is provided as a structural group on the cover and if the structural group comprises a locking device that can be actuated by the actuation device, which locking device holds the cover unit locked in the closed position on the sliding roof frame and unlocks it for the removal of the cover from the cover frame. This locking device provided for the operation of the entire cover unit can therefore also be removed with the cover since the above-cited bolting device or the bolting part assumes the bolting function when the cover frame is closed and the cover removed.

A vehicle such as, e.g., a passenger car comprises a vehicle roof 1 (see FIG. 1) with a fixed roof frame structure 2 and a sliding roof device 3 attached as a structural unit by a sliding roof frame 4 (see FIG. 6) to the roof frame structure 2. The sliding roof device 3 contains a movable cover unit 5 that is shiftably supported on a front guide rail 9 and on a rear guide rail 10 in the area of its two side edges 6 by a front support- and swing-out lever 7 and by a rear support and swing-out lever 8 (see especially FIGS. 2 to 4) respectively. The cover unit 5 can shift between a closed position in which a roof opening 11 that can be opened is closed (FIG. 6) and an open position with maximally opened roof opening 11 (FIG. 11), whereby upon a shift into intermediate positions with partially open roof opening 11 as well as in the open position the support- and swing-out levers 7 and 8 raise the cover unit 5 and shift it over a rear roof surface part 12 that follows the roof opening 11 and the closed cover unit 5 to the rear. This roof surface part 12 can be, e.g., a part of a fixed roof, an inserted, fixed covering or also another movable cover. The shifting of the cover unit 5 along the guide rails 9 and 10 takes place manually but can also basically be carried out by a drive device.
The axial and directional designations such as, e.g., “front”, “side”, “above” and “below” used in the description refer to a three-dimensional x-y-z vehicle coordinate system. The exemplary embodiment shows a sliding roof device with a cover unit 5 that can be shifted in the longitudinal direction of the vehicle or the x direction or in the longitudinal direction of the roof. However, a sliding roof design in accordance with the invention can also be provided with a cover unit arranged so that it can move, e.g., in the transverse direction of the vehicle or the y direction or in the direction transverse to the roof.
The cover unit 5 comprises a cover 13, e.g., a glass cover or a plastic cover, and a cover frame 14 to which the cover 13 is detachably attached. The cover frame 14 runs circumferentially under the edge area of the cover 13 and is therefore a substantially rectangular structural component with a large cover frame opening 15 in the exemplary embodiment corresponding to the shape of the cover. The front and rear support- and swing-out levers 7 and 8 are pivotably articulated to the cover frame 14 in front and rear pivot bearings 16 and 17 and can be raised and lowered by guide- and control cranks 18 and 19 of the guide rails 9 and 10 and can be moved along them.
The cover frame 14 comprises four holders 20 with support pins 21 associated with hooks 22 that are attached to the bottom of the cover 13 and project downward. The cover 13 is detachably attached to the cover frame in that it is suspended by the two front hooks 22 on the front support pins 21 and by the rear hooks 22 on the rear support pins 21.
The cover frame 14 contains two supports or support pegs 24 on its front cover transverse frame part 23 that especially project downward and pivotably support a bolt part 25. Each bolt part is shaped like an anchor with two opposing bolt hooks 26 and 27 and can be pivoted in such a manner about the support pin 24 that in a first bolting position the bolt hook 26 is in engagement with an engagement part (not shown, e.g., a peg or a pin) of the cover 13 and securely holds the cover 13 on the cover frame 14 (see, e.g., FIG. 6). The bolt part 25 can be pivoted from this first bolting position in the opposite direction into a second bolting position, e.g., manually (see FIG. 18), in which the bolt hook 27 is brought into engagement with an engagement part 28 arranged on a front transverse frame part 29 of the sliding roof frame 4. Therefore, in this second bolting position the bolt part 25 locks the cover frame 14 in the closed position on the sliding roof frame 4 and at the same time releases the lock of the cover 13 on the cover frame 14 so that the cover 13 can be removed from the secured, non-shiftable cover frame 14 and the cover frame opening 15 forms the freed roof opening 11.
A structural group 30 is arranged on the bottom of the cover 13 (FIGS. 4, 7 and 8) which group comprises a locking device 31, an arresting device 32 and an actuation device 33 for actuating and shifting the cover unit 5 as well as for actuating the locking device 31 and the arresting device 32. The locking device 31 comprises two bolt hooks 34 that are pivotably supported on a one-part or multi-part carrying component 35 of the structural group 30 by a pivot support 36 and on both sides relative to a vertical longitudinal central plane through the structural group 30 and the cover unit 5 and are therefore arranged at a distance from one another. A front hook end 37 of each bolt hook 34 extends forward from the pivot support 36. An articulation 38 of a correcting element 39 of an actuating mechanism is arranged on a section 40 of the bolt hook 34, which section is at the rear relative to the pivot support 36. The actuation of the two bolt hooks 34 in a simultaneous opposite pivoting takes place via the longitudinal shifting of an inner articulation 41 of the particular correcting element 39 in the longitudinal direction of the roof (shown in FIG. 8 by double arrow 42) by a handle 43 that can pivot by two supports 44 about a transverse pivot axis 45 on the carrier component 35 through approximately 90° and the intercalated actuation mechanism 46 in such a manner that in the horizontal rest position of the handle 43, which position is pivoted in against the carrier component 35 (see the FIGS. 6 and 7), the two bolt hooks 34 are pivoted against one another into a locking position and in a pivoted-out operating position of the handle 43 (see the FIGS. 4, 9 and 10) they are pivoted out of the bolted position into an open position. In the bolted position the bolt hooks 34 are in a bolting engagement with a closed cover unit 5 (FIG. 6) on an associated bolting engagement part 47 on the front transverse frame part 29 of the sliding roof frame 4 so that the cover unit 5 cannot be moved out of its closed position.
The arresting device 32 contains an arresting pin holder 48 with a laterally outwardly projecting arresting pin 49 on the two lateral ends of the carrier component 35. The arresting pin holder 48 is shiftably supported in the transverse direction or y direction on a support unit 50 attached on the carrier component 35 and is outwardly pretensioned into an outer position of rest by a pressure spring 51 received in a recess of the support unit 50 (see FIG. 13). Each arresting pin holder 48 is connected by a Bowden wire 53 containing a spring 52 to a pivot lever 54 (FIG. 8) that is supported in such a manner that it can pivot about a pivot shaft 55 centrally arranged on the carrier component 35 and that comprises connection points 56 for the two Bowden wires 53, that oppose one another relative to the pivot shaft 55 and are therefore uniformly spaced.
A slide actuating part 57 of the actuation device 33 is arranged on the bottom of the carrier component 35 in the vicinity of the handle 43 and is shiftably supported in the transverse direction or y direction on the carrier component 35. The slide actuating part 57 is coupled to the one arm of the pivoting lever 54 at a distance to the pivot shaft 55, e.g., by a pin connection or bolt connection on the connection 56 of the one Bowden wire 53. When the slide actuating part 57 is manually moved in the transverse or y direction to the right from the position shown in FIG. 8, the arresting pin holders 48 with the arresting pins 49 are drawn inward in a synchronous withdrawal motion contrary to the force of the pressure springs 51 by the pivot lever 54 that also pivots and by the two Bowden wires 53.
The arresting pin holder 48 comprises an oblong hole 58 (see FIG. 14) that extends next to the connection 59 of the Bowden wire 53 and its spring 52 in the direction of movement of the arresting pin holder 48 or in the y direction. A support pin 60 is shiftably received in the oblong hole 58. The support pin 60 is fastened on the outer end of an adjusting rod 61 and holds the adjusting rod 61 as a sliding bearing in a movable manner relative to the arresting pin holder 48, whereby the movement path is limited by the length of the oblong hole 58. The adjusting rod 61 extends inward up to the bolt hook 34 and is connected to it by a connecting articulation 62 arranged on the rear end of its rear section 40.
The arresting pins 49 are provided for the arresting engagement on, for example, three arresting engagement parts 63, 64 and 65, that are arranged on lateral longitudinal frame parts 66 of the sliding roof frame 4 along the movement path of the cover unit 5. Each arresting engagement part 63, 64 and 65 comprises a front arresting bevel 67 and a rear arresting bevel 68 on which the arresting pin 49 can slide during the shifting movement of the cover unit 5 in accordance with the direction of movement of the cover unit 5 and can move thereby inward as well as outward in the cross- or y direction. Furthermore, each arresting engagement part 63, 64 and 65 contains an arresting recess 69 that is cylindrical in particular, in a sliding surface 70 between the two arresting bevels 67 and 68. The arresting recess 69 is formed in such a manner that the arresting pin 49 sliding over the sliding surface 70 can move out into the arresting recess 69 on account of the pretension by the pressure spring 51. In its extended arresting position the arresting pin 49 blocks the cover unit 5 in this position (see, e.g., FIGS. 10 and 11) even if the cover unit 5 should be pushed, e.g., manually further.
The method of operation of the sliding roof device is described in the following.
In the closed position of the cover unit 5 (see FIG. 6) the cover 13 closes the roof opening 11 flush with the surrounding roof surface. The handle 43 is pivoted into its position of rest and the two bolt hooks 34 are pivoted by the actuation mechanism 46 into their bolting positions with a bolting engagement on the bolt engagement parts 47. The adjusting rods 61 were moved outward via the bolt hooks 43 and press the arresting pin holder 48 with the arresting pin 49 in a forced engagement on the outer end of the oblong hole 58 into a maximal outer position (see position of the FIGS. 12 and 13, arresting pin not shown in FIG. 6). In this position the arresting pin holder 48 has moved the pivot lever 54 and/or the slide actuating part 57 via the Bowden wire 53 against a stop and furthermore expanded the spring 52 under a buildup of tension. According to the exemplary embodiment an arresting engagement with arresting engagement parts is not provided in this position. The cover 13 is fastened on the cover frame 14 by the hooks 20 on the holders 22 and is in engagement with engagement parts of the cover 13 by the pivoted-back bolt parts 25 and the bolt hooks 26 so that the cover 13 is securely held on the cover frame 14.
In order to open the sliding roof device 3, at first the handle 43 is pivoted down (see FIG. 9), as a result of which the bolt hooks 34 are pivoted into their open position and the cover unit 5 is freed for shifting longitudinally along the guide rails 9 and 10. Moreover, the adjusting rods 61 are drawn inward into the position shown in the FIGS. 14 and 15, whereby initially the arresting pin holder follows the support pin 60 of the adjusting rod by the force of the tensioned spring 52, which pin rests on the outer end of the oblong hole 58 until the spring 52 has shortened to its unexpanded length free of spring power and exerts no return force on the arresting pin holder 48. The support pin 60 of the adjusting rod 61 is then located on the inside end of the oblong hole 58 of the arresting pin holder 48, that continues to be pretensioned to the outside by the pressure spring 51, whose spring power is less than the spring power of the spring 52 of the Bowden wire 53. In this position the arresting pin 49 is in a ready position in which it comes in contact with the front arresting bevel 67 during the backwards-directed manual shifting of the cover unit 5 and is shifted inwards by this arresting bevel against the power of the pressure spring 51 to the level of the sliding surface 70. The arresting pin holder 48 moves at this time relative to the arresting support pin 60, that is again moved in the oblong hole 58 toward its outer end (position of the arresting pin holder 48 shortly in front of the moving-in position shown in the FIGS. 16 and 17). The Bowden wire 53 forms with the relaxed spring 52 a largely pressure-stiff unit and is shifted inward by the arresting pin holder 48, as a result of which it pivots the pivot lever 54 and the slide actuating part 57 is also shifted.
During the further shifting movement of the cover unit 5 the arresting pin 49 reaches the arresting recess 69 into which it is extended by the spring power of the pressure spring 51 and pressed in. The arresting device 32 reassumes the position shown in the FIGS. 14 and 15 and the arresting pin blocks the cover unit 5 in its extended arresting position against further shifting (position according to the FIGS. 10 and 11). The pivot lever 54 has been pivoted back again via the also shifted Bowden wire 53 and the slide actuating part 57 is also located back in its initial position.
In order to shift the cover unit 5 further by the handle 43, the slide actuating part 57 arranged in the vicinity of the handle 43 is manually activated or shifted, as a result of which the arresting pin 49 is drawn out of the arresting recess 69 by the pivoting pivot lever 54 and the Bowden wire 53 with the spring 52. After the arresting engagement has been ended, the cover unit 5 can be shifted further by the handle 43. The activation of the slide actuating part 57 can be ended.
The described procedure is repeated at each of the following arresting engagement parts 64 and 65. In order to move the cover unit 5 into the open position according to FIGS. 10 and 11 without the described interruption of movement or arresting at at least one of the arresting engagement parts 63, 64 or 65 the slide actuating part 57 can be completely activated or shifted during the opening movement already upon reaching the first arresting engagement part 63 and held in the position so that the arresting device 32 and in particular the arresting pin 49 assume the withdrawn position shown in the FIGS. 16 and 17 in which no arresting can take place.
For the complete freeing of the roof opening 11 the cover unit 5 is shifted into the position shown in FIG. 10. If the slide actuating part 57 is located without manual activation in its initial position, the arresting pin 49 can extend into the arresting recess 69 of the rear arresting engagement part 65 and therefore hold the cover unit 5 locked in its open position. When the handle 43 is pivoted into its horizontal position of rest (FIG. 11) the two arresting pins 49 are moved out into their maximal arresting position (position according to FIGS. 12 and 13) by the pivoting bolt hooks 34 and the adjusting rods 61.
In order to close the roof opening 11 at least partially, the handle 43 is pivoted down and the cover unit 5 is shifted forward by the handle 43. If the slide actuating part 57 is not actuated at first, a locking will take place on the rear arresting engagement part 65 that can be canceled by activating the slide actuating part 57 in the described manner. If the cover unit 5 is to be moved in an uninterrupted sliding motion into its front closed position, then the slide actuating part 57 is activated at once and the arresting pin 49 is held in its withdrawn position.
The arresting device 32 also makes possible a blocking of the cover unit 5 if the latter is arranged in a partial opening position without locking and a high acceleration occurs such as, e.g., during a collision that suddenly moves the cover unit 5. Upon reaching the next arresting engagement part a locking will take place that prevents a further moving of the cover unit 5.
The freeing of a roof opening can also take place by removing the cover 13 from the cover frame 14 arranged in the closed position. Starting from the closed position of the cover unit 5 in accordance with FIG. 6 the two bolt parts 25 are separated from the bolting engagement on the cover 13 and brought in bolting engagement on the engagement part 28 of the front transverse frame part 29 of the sliding roof frame 4 and pivoted, especially manually. The cover frame 14 is therefore fixed on the sliding roof frame 4 and can no longer be shifted on the rails 9 and 10. During the pivoting down of the handle 43 the bolt hooks 34 are separated from their locking on the bolting engagement parts 47. Therefore, the cover can be removed from the cover frame 14. The entire structural group 30 for actuation, locking and arresting is also removed with the cover 13 so that the freed cover frame opening 15 also makes a comparatively large roof opening available.
The carrier component 35 of the structural group 30 is connected via several connections such as, e.g., screw connections 71 to the cover 13 on its bottom. The cover 13 is manufactured, e.g., from a plastic material or a composite material on which screw connections are possible. The structural group 30 can comprise a one-part or multipart covering 72.
The spring 52 on the Bowden wire 52 is provided for tolerance compensation in the mechanical chain between the arresting pin holder 48 and the pivot lever 54.
The individual features of the invention disclosed in the specification and using the exemplary embodiments as well as in the figures can be combined in any technically purposeful arrangements and shapes with the subject matter of the invention in its general form.
