A shape member 14 of the air deflector 12 is supported at the other end of the lift lever 17. The middle section of the lift lever 17 is supported by a pin 20 at an inclining guide section 24 which inclines and is formed at the cradle 15, thereby guiding so that the upper end section of the lift lever 17 draws an approximately vertical movement locus.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle roof air deflector device having a slidable cover for selectively closing or at least partially opening a roof opening.

(Prior Art) Conventionally, an air deflector device for a vehicle roof having a slidable cover is provided at the front edge of the roof opening at right angles to the front edge, and has an elongated structure. It can be raised and lowered vertically. The lifting device is loaded by a spring in the direction of the operating position of the air deflector,
One lever end carries the air deflector, and as the cover is slid into the closed position against the action of the spring, the other lever end is loaded to lower the air deflector into the inoperative position.

An air deflector of the above-mentioned type for a vehicle roof with a slidable cover is known from Japanese Publication No. 62-62527. This air deflector is provided above the water gutter in the front area. The lifting device has a lifting lever or lifting arm that is pivotable about a fixed axis extending in the longitudinal direction of the vehicle. An air deflector is attached to the end of the lift lever opposite to the axis via a slotted hole, and the air deflector moves almost vertically when rising to the operating position, and when moving to the non-operating position. It also moves essentially vertically when traveling to.

(Problem to be Solved by the Invention) However, in the above-mentioned prior art, the air deflector must at least partially absorb the operating force when rising to the operating position and descending to the non-operating position. It won't happen.

Therefore, the air deflector must also have sufficient strength to absorb the above forces and must be designed to be relatively thick. As a result, the overall weight is heavy, and installation is difficult if the fixed roof surface is strongly curved or if the roof opening is strongly curved.

The present invention overcomes these problems and is designed to be lightweight.
Can be installed without problems even in the case of strongly curved fixed roof surfaces or strongly curved roof openings, with lifting devices on sliding or sliding tilt roofs and actuating devices that operate when the cover is slid into the closed position. An object of the present invention is to provide an air deflector device for a vehicle roof having a slidable cover that can be installed as compactly as possible, that is, as a flat structure.

(Means for Solving the Problems) The present invention employs the following technical means to achieve the above-mentioned objects. That is, an air deflector for a vehicle roof having a slidable cover for selectively closing or at least partially opening a roof opening, the air deflector having a front edge of the roof opening that It can be raised and lowered essentially vertically by means of a lifting device which is arranged at right angles to the air deflector and is of elongated construction and which has a lifting lever, said lifting lever being loaded by a spring in the direction of the operating position of the air deflector and allowing one A lever end carries an air deflector, and when the cover is slid into the closed position against the action of a spring, another lever end is loaded to lower the air deflector to the inoperative position. The lifting lever 17 is movably guided along a connecting path 22 oriented approximately perpendicular to the sliding direction of the cover 11 such that the lever end 18 carrying the deflector 1.12 follows an approximately vertical trajectory of movement. It is characterized by this.

(Function) The lifting lever is movably guided along a connecting path oriented approximately perpendicular to the sliding direction of the cover, and the end of the lever carrying the air deflector follows an approximately perpendicular trajectory of movement. The movable lift lever guide absorbs the operating force when the air deflector is raised to the operating position and lowered to the non-operational position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which examples are shown.

FIG. 1 is a plan view of a vehicle roof equipped with an air deflector, FIG. 2 is a sectional view taken along the line nn in FIG. Figure 4 is
4 is a partial view similar to FIG. 3 showing a displaceable stop; FIG.

A preferred embodiment of an air deflector 1 for a vehicle roof 2 will be described with reference to FIGS. 1-3. FIG. 1 shows a plan view of the vehicle roof. In this case, for the sake of clarity, only the parts in the area of the front edge of the vehicle roof 2 are shown, while the movement mechanism of the cover is shown only in outline, as it is customary for sliding and/or sliding roofs.

The fixed roof surface 4 of the vehicle is provided with an opening into which a frame 5 defining a roof opening 6 is inserted.

The front side, ie, the horizontal side, of the roof opening 6 is indicated by 68, and the contracted side is similarly indicated by 6b. The longitudinal axis of the vehicle pointing in the direction of travel is indicated by an arrow 7. A cover mechanism 8 (of which only the front sliding member 9 that can slide on the sliding rail 10 of the frame 5 is shown) is shown along the contracted side 6b. A cover 11 (FIG. 2) of the vehicle roof is connected to the cover mechanism 8 and serves to close or at least partially open the roof opening 6. Depending on the construction of the vehicle roof 2, the cover 11 can be raised, ie in the case of a so-called slide-tilt roof, in which the cover 11 is raised and lowered at one edge.

In FIGS. 1 to 3, an air deflector equipped with a lifting device 13 is indicated generally at 12. In this case, the lifting device 13 places the shaped part 14 of the air deflector 12 in an almost vertically raised operating position (indicated by a chain line in FIG. (indicated by the solid line in Figure 2).

As can be seen in particular from FIG. 2.3, the lifting device 13 has at least one (1)
Preferably, the two receivers have a pedestal 15. This support platform 15 serves to guide the movement of the lifting lever 17 of the lifting device 13. In this case, the lifting lever 17 essentially has the following features:
It has two ends. As shown in FIG. 3, an air deflector shaped member 14 is attached to the end 18 of the lift lever 17. The other end 19 and the central area of the lifting lever 17 are secured to the platform 1 by means of a pin or bolt 20.21.
5 (this will be explained in more detail below). Especially the second one.
As is clear from FIG. 3, the connecting path 22 has a substantially horizontal first
It includes a section 23 and a second guide section 24 forming a slight obtuse angle to the section 23. A bin 21 at the load end 19 of the lifting lever 17 is guided in the first guide section 23, and a bin 20 provided approximately at the center of the lifting lever 17 is guided in the second guide section 24. A lifting spring 25 is provided which is connected at one end to the load end 19, i.e. preferably latched to a pin 21 provided on said load end, and whose other end is fixed immovably to the support 15. Furthermore, a force FB in the opposite direction to the force FA applied from the lift spring 25 is applied to the load end 19 of the lift lever 17.
9 is provided with a tensile force transmitting device 26. That is, this tensile force transmission device 26 resists the action of the lifting spring 25.

In particular, as is clear from FIG. 2, in which the non-operating position of the lifting device 13 is shown by a solid line, and the operating position is shown by a broken line, and FIG. 3, which is an enlarged view, when the cover 11 is opened, the force acting in the FB direction is , the lifting spring 25 does not act on the load end 19 of the lifting lever 17 via the tensile force transmission device 26.
A tensile force is applied to the lever end in the direction of force application FA, ie to the right in FIG. The lifting lever 17 is thus driven by both sections 23 , 24 forming a connecting channel 22 oriented approximately perpendicular to the sliding direction of the cover 11 , and the lifting lever end 18 carrying the air deflector 12 is
As shown by the chain line in Figure 2, it draws a nearly vertical motion trajectory. That is, the air deflector 12 is essentially raised vertically at the leading edge 6a of the roof opening 6 into the operating position.

If the cover 11 is in the vicinity of the closed position in which it closes the roof opening 6 and the sliding member 9 arranged on the cover mechanism 8 assumes the position shown in FIG. The actuating lever 27 is pivoted by the sliding member 9, and a tensile force transmission device 26, which in the illustrated embodiment is connected to the free end of the actuating lever 27, transmits a tensile force in the direction of the arrow FB. Starting from the operating position of the air deflector 12 (FIG. 3), the load end 19 of the lifting lever 17 is therefore pulled to the right by the pulling force transmission device 26.

The lifting lever 17 is then guided by the bin 20.21 and the two guide sections 23.24 back into the non-operating position shown in FIG. 2, so that the lifting lever 1
The air deflector-shaped member 14 attached to the end 18 of 7 is returned to its non-operating position, shown in solid lines in FIG. 2, along a substantially vertical trajectory.

Unlike the illustrated embodiment, the tensile force transmission station 26 can include a tensile loft. This tension rod is, for example,
At one end it cooperates directly with the cover mechanism, e.g. the sliding member 9
receives tensile force through. Furthermore, on the right side of the extension line of the vehicle roof 2, as shown in FIG.
Preferably, the unit for controlling the tensile force transmission device 26 and the actuating lever 27 is provided in mirror-image symmetry. The connecting channel 22 with the guide section 23 , 24 can be provided directly on a part of the frame 5 , such that the lifting device 13 is integrated into the frame 5 .

As shown in FIG. 4, a displaceable stop 30 is preferably arranged in the horizontal guide section 23 of the connecting channel 22, with which the operating position of the air deflector 12 can be adjusted or harmonized. Instead of the above-mentioned displaceable stop 30, a corresponding device can also be provided in the area of action of the tensile force transmission device 26.

As is clear from the above description of the function of the air deflector 1 and the associated lifting device 13, the air deflector l
is essentially vertically moved up and down at the front edge 6a of the roof opening 6. In this case, the lifting device 13 has a shape of the air deflector, since the load force for the lifting movement of the air deflector acts on the lifting lever 17 of the lifting device 13, and the shape member 14 of the air deflector does not require an operating force. The member 14 can be designed to be lightweight and may have a thin wall.
Therefore, it can be easily adapted to the shape of the boundary of the roof opening 6. A very flat air deflector 1 for the vehicle roof 2 is thus obtained. Furthermore, the air deflector profile 14 can extend as far as the transition area 31 from the lateral edge 6a to the constricted edge 6b of the roof opening 6, so that the air deflection function of the air deflector I is substantially improved.

The invention is, of course, not limited to the details described with reference to the exemplary embodiments, but various design changes are possible within the framework of the invention, if necessary. In the design according to the invention of the air deflector 1, the air deflector is essentially vertically fed in and out, and the lifting device 13 is arranged in the area of the lateral side 6a of the roof opening 6 and is not designed flatly. It is essential to say that there is. Since the air deflector I can be designed from thin-walled material, it can easily be adapted in terms of its shape to roof openings that are curved in the area of the front side, ie the transverse side 6a, seen in plan.

(Effects of the Invention) The present invention provides that the lifting lever is movably guided along a connecting path oriented substantially perpendicular to the sliding direction of the cover, and thus the end of the lever carrying the air deflector can be moved in a substantially vertical direction. Draw a trajectory.

The air deflector device according to the invention for a vehicle roof with a slidable cover has a lifting lever movably guided perpendicular to the sliding direction of the cover, ie at right angles to the direction of travel of the vehicle. In this configuration, the guide of the movable lifting lever absorbs the actuation forces when raising the air deflector to the operating position and lowering it to the non-operating position, making the body of the air deflector lighter (in particular, thinner). ) can be designed. With this design, the air deflector occupies only a small amount of space in its lowered, non-operating position.
Therefore, the slide roof or slide tilt roof can be designed to be flat. On the other hand, in the case of the air deflector device according to the present invention, since the lift lever can be installed in the range of the horizontal side of the roof opening, the air deflector can be extended to the corner range of the transition part from the horizontal side of the roof opening to the contracted side. Thus, the formation of voids and the generation of noise due to these voids can be avoided in the above range.

Furthermore, the above-mentioned arrangement of the lifting lever does not apply to vehicle roofs where the fixed roof surface is strongly curved in the direction of travel and in the direction perpendicular thereto, or where the front edge of the roof opening is curved in plan view. can also incorporate an air deflector device.

In order to guide the lifting lever, it is advantageous to provide a connecting channel which includes a first guide section which is expediently approximately horizontal and a second guide section which is at a slightly obtuse angle to said section. A connecting channel constructed in this way provides connecting channel sections that run approximately straight, but are not mutually perpendicular. With a guide configured in this way, the fixing point of the air deflector at one end of the lifting lever moves along a slightly curved trajectory that is not perceptible to the eye, so that during this guided movement of the lifting lever, the air deflector is driven essentially vertically. The production of the coupling guide of the lifting lever is simplified by dividing the connecting path into two approximately straight sections, one for compensating for the slightly curved curved path in the area of the fixing point of the lifting lever relative to the air deflector. It is sufficient to provide a long length, so
The strength of the air deflector is not significantly reduced.

It is preferable that the first guide section of the connection path guides the end of the lift lever that is subjected to the load when the cover slides, and that the second guide section guides approximately the center of the lift lever. The area can be provided with a pin that engages in both guide sections of the connecting channel, in which case the lifting lever is movably guided at two points by a guide configured as a connecting channel, so that the entire As seen, it is essentially pivoted movably about two axes extending approximately perpendicular to the sliding direction of the cover.

Preferably, the lifting lever is constructed as an angled lever. In this case, however, the lifting lever is designed in one piece so that it is slightly inclined with respect to the horizontal plane from the center to each lever end.

According to an advantageous embodiment of the invention, a spring acting in the operating position or in the upward direction of the air deflector acts on the lever end which is loaded during sliding of the cover, and fixes the other end of the lever immovably. That is, since the lifting force for moving the air deflector to the operating position acts on the end of the lifting lever opposite to the air deflector, the actuating force of the lifting link is absorbed by the lifting lever and the associated guide. Therefore, the air deflector can be designed with respect to its shape and dimensions to optimally match the desired air deflection (air deflection > a). The spring force for the upward movement of the deflector can be predetermined according to the requirements.

For adjustment of the operating position of the air deflector, it covers a range of tensile force transmission devices that act as guides at each end or section of the link or in cooperation with the sliding movement of the cover to load the lifting lever of the air deflector. A movable stopper is provided.

This tensile force transmission device can, for example, consist of a tension rope or a tension rod. In this way, the lifting height of the air deflector can be adapted to the desired given conditions without changing the basic form of the lifting device for the air deflector.

Preferably, the tensile force transmission device acts on the load end of the lifting lever. In this configuration, the force required for the upward movement exerted by the spring and the tensile force required to lower the air deflector to the inactive position act on the same lever end of the lift lever in close proximity to each other. In this way, tilting relative to the connecting path is avoided, so that mobility of the lifting lever is achieved and wear is reduced to a maximum.

In order that the air deflector and its actuating device can be constructed as flat as possible, according to an advantageous embodiment of the invention, it is pivotable about a vertical axis and cooperates with the load end of the lifting lever to bring the cover into the closed position. An operating lever that operates when the roof opening is moved is provided near the contracted side of the roof opening. In this type of configuration, the actuating lever can be pivoted approximately in the plane of the roof opening or parallel to said plane, so that the structural height of this type of vehicle roof can be reduced and the actuating device of the air deflector can be made compact. Can be installed.

Preferably, the two lifting levers are arranged on the sides of the roof opening, spaced apart from each other and mirror-symmetrical with respect to the lifting levers and their movement. In this case, of course, an actuation device associated with both lifting levers is provided on each contracted side of the roof opening.

To facilitate the production and installation of air deflectors,
Preferably, the guide (for example the link or a section thereof) is integrated into the frame of the vehicle roof. Furthermore, the structural height of the air deflector lifting device can thus be reduced.
