Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vehicle having a slidable cover for selectively closing and at least partially opening a roof opening, and a slide canopy which can be moved at least topologically independently of the cover. A roof wind deflector, wherein the wind deflector comprises:
It is provided at the front edge of the roof opening, is configured vertically long, is tilted up to the operating position by a tilt-up device,
The tilt-up device is installed on both sides of the roof opening, and is pivotally connected to a frame fixed to the roof in a range of the rear end of the device far from the wind deflector. It is of the type in which the wind deflector is pivoted to a position where it is lowered to a rest position.

[0002]

BACKGROUND OF THE INVENTION A wind deflector of the type mentioned at the outset is known from DE-A 37 43 476. In this case, the position of the wind deflector is related to the position of the cover. The purpose of a wind deflector on a vehicle roof is to make the air flow condition suitable for reducing air flow noise (also called wind flutter) in the vehicle when the cover is opened. For this purpose, the wind deflector is adapted to the requirements of the vehicle.

However, wind deflectors exhibit their optimal characteristics only of course up to a certain maximum speed. Other measures must be taken to minimize wind flutter noise in the passenger compartment. In one of the above measures, the shape of the wind deflector is changed. Thus, it is known from DE-A 37 43 476, for example, to enlarge the area of a wind deflector beyond its free lateral edge by means of a supplementary slat mechanism. In this case, a special, and possibly manual, drive is provided to separate the slat from the wind deflector body. Such area expansion of the wind deflector is always performed by the user. Another approach to minimizing wind flutter noise in the passenger compartment is to reduce the opening width by increasing the running speed and moving the cover towards its closed position until the wind flutter noise is reduced.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wind deflector which can be placed in an optimum state in order to minimize wind flutter noise in a vehicle compartment in view of the above prior art.

[0005]

This problem is solved by the following technical means. That is, the present invention provides a vehicle roof having a slidable cover for selectively closing and at least partially opening a roof opening, and a slide canopy movable at least topologically independently of the cover. A wind deflector, wherein the wind deflector is provided at a front edge of the roof opening, is configured vertically, and is tilted up to an operating position by a tilt-up device installed on a side, and the tilt-up device is In a type in which the wind deflector is swiveled to a position where the wind deflector is lowered to the rest position by sliding the cover to the cover closed position, and is pivotally attached to a frame fixed to the roof, the operation position is tilted up. Some wind deflectors have a slide canopy that is independent of the drive of the cover with regard to the degree of tilt-up. Is controlled by the braking system, Therefore, the drive device is configured to tilt-up device engages the wind deflector.

In other words, based on the above characteristics, the degree of tilt-up of the wind deflector is adjusted independently of the cover position, thus guaranteeing an optimal effect on wind flutter noise in the passenger compartment. Adjustment of the degree of tilting of the wind deflector is achieved according to the invention by mechanically coupling the tilting device of the wind deflector to a slide canopy moved by a drive independent of the drive of the cover. . The mechanical connection between the tilt-up device of the wind deflector and the slide canopy is achieved by a control cam (curved surface) in which one element is formed in the tilt-up device and the other element is formed in the slider.
Advantageously, this is achieved by a / projection unit.

In this case, the slider is loaded by a return spring to a rest position in which the control cam / projection unit does not act on the degree of tilt-up of the tilt-up device, while
Pulling out the drive of the slide canopy from a rest position in which the control cam / projection unit blocks the tilt-up degree of the tilt-up device in order to optimize the operation of the wind deflector, ie the tilt-up degree of the wind deflector in a desired manner. The cable is pulled out against the above-mentioned spring force. It is advantageous if the slider is guided on rails formed from the components of the roof opening frame through which the pull-out cable of the drive of the slide canopy is also guided. The wind deflector tilt-up device, which is preferably formed in the form of a lever in a known manner, is always placed under load, thus ensuring that the wind deflector tilt-up mechanism has heretofore completely inevitable rattling. It is advantageous if the slider is in the rest position so that a force connection is maintained between the projection of the projection / control cam unit and the control cam.

Furthermore, it is particularly advantageous if the displacement of the wind deflector is effected automatically as a function of vehicle speed-related measurements (eg, tachometer signals, dynamic pressure or noise signals in the vehicle interior space).

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a vehicle roof with a roof opening, which is selectively closed or at least partially opened by two cover elements, generally at 1. The cover elements are a slat-shaped wind deflector 2 and a slide cover 3 provided behind the wind deflector when viewed in the running direction. The front edge of the wind deflector 2 is pivotally connected to a fixed roof of the vehicle by a pivot 4 on the side of the roof opening.
The wind deflector 2 is laterally limited by two eyelets 5 projecting from the lower surface of the wind deflector (only the left eyelet 5 is shown in FIG. 1). A support opening 6 for a bolt 7 of a tilt-up lever 8 (shown in FIGS. 2 and 3 but not shown in FIG. 1) is provided at the rear end of the eyeboard 5 when viewed in the running direction. The tilt up lever is
At the end opposite to the end provided with the bolt 7, a pivot hinge 8 a is pivotably connected about an axis parallel to the wind deflector pivot 4. Further, a tilt-up lever 8 of this type is provided on each side of the wind deflector 2.

Guide rails 9 fixed to the vehicle roof are provided on both sides of the cover elements 2 and 3, and drive means (not shown) for the slide cover 3 is guided on the guide rails 9. Further, a sliding shoe 21 of a slidable canopy of the vehicle is guided on the guide rail 9.
The cable 2 which functions as a driving means of a slidable vehicle canopy 19 and is driven by an electric driving device 20
2 surrounds the lead-out cable 10 guided by the vertical groove 11 of the guide rail 9 in a known manner. Further, the guide rail 9
It encloses a rail 12 that extends parallel to the vertical groove 11 and spaced below it. A slider 13 slides on the rail 12, but the slider 13 can slide along the rail 12 essentially without play because the inner contour of the slider matches the outer contour of the rail 12. Seen in the running direction, the front end of the slider 13 is loaded by a return spring 14 in the running direction to a rest position determined by the support block 15 of the pivot hinge. In this case, the support block includes
A protrusion 16 fixed to the slider 13 and projecting laterally from the slider in the direction of the tilt-up lever 6 abuts. The projection 16 rests on a control cam 17 formed by the upper surface of the web 18. The web projects laterally from the tilt-up lever 8 in the direction of the slider 13 within the range of the pivot hinge 8a, is fixed to the tilt-up lever 8, and extends to the support base 15 of the pivot lever 8a. The control cam 17 is
It rises in a direction opposite to the running direction and cooperates with the projection 16 of the slider 13 in a manner to be described below, so that the wind deflector 2 is independent of the drive of the cover 3, preferably at the speed of travel of the vehicle Is controlled by the drive of the slide canopy, which is controlled in dependence on the

When the slide cover 3 is in the closed position,
The tilt-up lever 8 is brought into contact with the lower surface of the cover by a spring force. When the slide cover 3 moves to the open position, and thus the tilt-up lever 8 separates from the lower surface of the cover, the tilt-up lever 8 is turned from the rest position to the upper operating position by a spring force, and thus, when the vehicle is running, A deflector function is developed. Medium,
That is, when the slide cover 3 is opened at a traveling speed lower than the traveling speed threshold, the slide canopy 19
However, it is preferable to be at a predetermined open position that can be changed based on the occupant's preference. Above the predetermined speed, the slide canopy is further slid in the opening direction from its position at a medium running speed, corresponding to the actual running speed, and thus the pull-out cable 10 is It is slid in the opposite direction, that is, toward the front of the vehicle. In this case, the extraction cable 10 has not
The slider 13 at the rest position, which is in contact with the slider 5, is driven. During the feed movement of the slider 13, the projection 16 engages with the control cam 17 and moves along the control cam at a position corresponding to the stroke of the pull-out cable 10 based on the displacement of the slide canopy of the roof (for example, the position in FIG. 3). ) Is reached.

When the projection 16 moves relative to the control cam 17 while the height position of the projection 16 remains unchanged, the tilt-up lever 8 is pivoted from its previous position, and therefore the tilt-up degree of the wind deflector is increased. Is correspondingly reduced, so that the action of the wind deflector is adapted to high running speeds. On the other hand, when the traveling speed of the vehicle decreases and the traveling speed falls below the above-described threshold value, the slide canopy is returned to the original position, and thus the pull-out cable 10 performs a stroke motion in the reverse direction. The slider 13 follows the stroke motion in the reverse direction. This is because the slider 13 is kept in contact with the closed end of the extraction cable 10 until the protrusion 16 of the slider comes into contact with the support 15. Slider 1
During this return movement of 3, the projection also runs in the opposite direction on the control cam 17, thus the tilt-up lever 8 occupies the original position at which the wind deflector 2 assumes the original tilt-up degree.

Even in the rest position where the projection 16 abuts on the support 15, a load is applied to the control cam 17 against the tilt-up spring of the tilt-up lever 8, and thus the tilt-up lever 8 (on both sides of the wind deflector, Each,
The tilt-up lever 8 is provided) and the wind deflector 2 is always kept in a load state, so that the wind deflector 2 in the tilt-up mechanism has looseness.
It is surely blocked. At various speeds, multiple positions of the wind deflector 2 can be achieved in the manner described above.
In this case, a manual operation of the drive device 20 of the slide canopy 19 by the driver is also conceivable, as is an automatic method depending on the measured value of the running speed. In addition to the tachometer signal, the operation is based on dynamic pressure measurements or noise values measured, for example, by a microphone in the interior space of the vehicle.

Wind deflectors in the sense of the invention are not only wind deflectors (see FIG. 1) which serve to cover a part of the vehicle roof, but also below the cover when the cover is closed and are only tilted up after the cover is opened. Wind deflectors are also covered.

[0015]

According to the invention, the degree of tilt-up of the wind deflector is adjusted independently of the cover position, thus guaranteeing an optimal effect on wind flutter noise in the passenger compartment.
