Description

Wind deflector of a vehicle roof

The invention relates to a wind deflector of a vehicle roof with the features of the preamble of claim 1.

From DE 199 55 712 A1 a wind deflector of a vehicle roof has become known, which is arranged on a roof frame in the front region of a roof opening and in a roof frame arranged receiving space and retractable, wherein it is guided on slideways and parallel to its surface is moved. The wind deflector is biased by means of a biasing assembly in its extended position and can be retracted according to an embodiment by direct contact with the roof opening closing lid. For the sliding guides a comparatively large space in the direction of movement of the wind deflector is required in the receiving space on the roof frame.

Further, as an internal prior art (not yet published), a wind deflector is known, which is pressed by the front edge of the sunroof cover down and released when opening. The locking of the wind deflector in the lower position is done by manual operation by hand. These two functions are made possible by an extended "heart curve function." The term "heart curve" is here referred to a heart-shaped cam, the "apex" facing upward, and their inwardly converging arcuate curves in their point of contact as a detent recess for If the wind deflector is now operated only by hand on such a "normal heart curve", it is necessary to create 4 mm more space in the direction of the Z-axis, ie in the height of the vehicle the clearance of the cam must be present below the heart curve and at the same time the lid must not touch the deflector. In a first known variant, it is necessary (if desired - for example, when used in a convertible), the wind deflector always by hand to push down, the cover (or the roof top of the convertible top) him with each actuation upwards entraining. The optics here is a disadvantage, since the

Wind deflector is always 8 mm above the lower position. In a second known variant of the cowl must be moved 4 mm down to ensure the function of the heart curve. Here the wind deflector is also 4 mm above the lower position and thus also has a visual disadvantage.

The object of the invention is to provide a wind deflector mentioned above, which is improved in terms of its functionality and its storage on the vehicle.

This object is achieved in the above-mentioned wind deflector according to the invention that a relative to this movable locking device is arranged on the wind deflector, which cooperates with a counter-element on the roof frame. By the invention, a wind deflector is provided which requires only a small space and whose locking device allows the wind deflector only is transferred to its operating position at the request of the driver or the occupant. From this operating position, it can be brought both manually and automatically by the closing roof part in its lowered rest position. The movable roof part is z. As a cover of a sliding or spoiler roof or a front roof part of a storable Cabrioletdaches.

Advantageous embodiments of the invention are specified in the subclaims.

In an advantageous embodiment of the invention, the locking element in the vertical direction, d. H. movable in the direction of the Z-axis of the vehicle. According to an alternative embodiment, the locking element in the horizontal direction, d. H. movable in the direction of the X axis. The locking element is either linearly displaceable or pivotally mounted on the wind deflector or a component connected thereto.

The counter-element is preferably designed as a locking lever, the pivoting or sliding movement in the horizontal direction, d. H. in the direction of the X-axis of the vehicle.

The locking lever and the locking element are engageable with each other via a locking lug or a locking hook.

The locking lever is preferably movable against the pressure of a spring.

The locking device and the counter element preferably have inclined inclined surfaces, which is a sliding latching of the two parts when lowering the wind deflector in its rest position and a Canceling the latching effect in a relative movement of the locking device to the wind deflector.

Two exemplary embodiments of a wind deflector according to the invention will be explained in more detail below with reference to the drawing. It shows:

FIG. 12 shows the illustration according to FIG. 11, omitting the operator's hand; FIG. and

Fig. 13 is a section through the locking device of FIG. 9 in the locked position of rest. A vehicle 1 (see FIG. 1) comprises a vehicle roof 2 with a roof frame arrangement which has a front roof transverse spar or cowl 3 above a windshield 4 and both sides a respective front movable side spar 5 and 5 'and a roof-fixed rear side spar 6 and 6', which extends approximately from the B-pillar 7 to the C-pillar 8. A roof opening 9 extends between the cowl 3 and the two movable side rails 5 and 5 'and is bounded on the rear by a rear roof cross member 10 which is fixedly connected to the rear side rails 6 and 6' or the B-pillars 7. A rear fixed roof section 11 extends between the rear side rails 6 and 6 'and from the rear roof cross member 10 to a further roof cross member at the end of the vehicle roof 2 above the rear window.

A lid 12, z. As a glass cover of an externally guided sunroof, is provided for closing and at least partially releasing the roof opening 9. The cover 12 is slidably mounted in the region of its front edge 13 on both sides by means of a bearing unit on a respective guide means having a guide rail on the front side rail 5, 5 'and a further guide rail on the rear side rail 6, 6' (the guide rails are not shown). The cover 12 is laterally displaceably mounted in the region of its rear edge 14 by means of a respective support lever 15 on an associated guide rail on the rear side rail 6, 6 '. To release the roof opening 9, the lid 12 is raised by means of the bearing units at its rear edge 14 and moved back over the rear fixed roof section 11 (position shown in FIG. 1). Such a cover 12 with support levers and drive mechanism is disclosed in DE 197 13 347 C1, to which reference is made in this regard for further explanation.

Each front side rail 5, 5 'is from its functional or external position (see Fig. 1), in which it the A-pillar 16, 16' and the cowl 3 with the fixed rear side rail 6, 6 'connects and provides the guide rail for storing or moving the lid 12, displaced into an inner position as soon as the lid 12 is arranged in a rear open position and without bearing engagement with the guide rail on the front side rail 5, 5' (Fig. 1). The displacement of the side rails 5, 5 'is described in the German patent application with the file number 103 31 144 A1, which is incorporated herein by reference.

Instead of a cover 12 can be used as a movable roof part and a convertible top, the front roof top to release a partial opening initially on guide rails on the side rails 5 and 5 'moved backwards, as is known for example from the BMW Mini-Cooper convertible.

At the cowl 3, a wind deflector 17 is arranged (see Fig. 2 to 13), the opening of the lid 12 and the convertible top first by a locking device described in detail below in its rest position in a receiving space 19 in the region of the roof opening. 9 surrounding roof frame is held.

There are two variants of a simple locking device shown, which are always locked in the maximum lowermost position of the wind deflector 17 by hand (manually).

It is shown in FIGS. 2 to 7 show a first variant in which an actuating lever 26 forming part of the locking device 22 is actuated forwards in the "X" direction by means of a handle 24. The coordinates X, Y and Z customary in vehicle construction are indicated in FIG ,

In the Fign. 8 to 13, a second variant is shown, in which a part of the locking device 22 forming the actuating lever 26 means a handle 24A is actuated by a pivoting movement in "Z" direction downwards.

The issued wind deflector is shown in Fig. 2 in an overall view.

An aperture 25 inserted into a recess on the wind deflector 17 receives on the one hand the actuating components and serves on the other as a design panel for the mechanical components in Windabweiserprofil 20. The actuating components of the locking device 22 are formed by the at the aperture 25 in a lower bearing 27 by means of a horizontal pivot axis 28 pivotally mounted actuating lever 26 which can be pressed by means of the handle 24 against the tensile force of a spring 31 (see FIG. 4) forward.

In a formed on the roof frame receiving space 19 for the wind deflector 17 which cooperating with the locking device 22 components are housed. These consist of a connected to the roof frame bearing 32 to which a locking lever 23 is pivotally mounted against the pressure of a spring 33 to the front. The locking lever 23 has at its rear in its upper region a sloping from top to bottom inclined surface 35, which then merges into a horizontally extending forward locking hook 34. On the actuating lever 26 a sloping front to back oblique surface 30 is provided, which cooperates with the inclined surface 35.

At the front of the locking lever 23, a bolt 37 for holding the spring 33 is arranged. At a distance in front of vertical plate 38 of the bearing 32, a further bolt 36 is provided, which also serves to hold the spring 33. In Fig. 3 of the locked in its lower position wind deflector 17 is shown in an overall view.

Hereinafter, the function of the embodiment shown in FIGS. 2 to 8 described first variant described. In Fig. 4, the locked position from the rear and in Fig. 5, the locked position is shown from the front. In these figures, the diaphragm 25 is not shown to ensure free access to the other components. In the locking position shown in FIGS. 4 and 5, the locking hook 34 of the locking lever 23 engages from above via the locking lug 29 of the actuating lever 26. The pivot axis 28 of the actuating lever 26 and the pivot axis 39 of the locking lever 23 are vertically below the surfaces of the locking lug 29 and Locking hook 34, thus no force is applied from the lock on the spring 33 of the locking lever 23.

Since the spring 33 of the locking lever 23 brings a higher force on the locking lever on the operating lever 26 as the spring 31 of the operating lever on the actuating lever, the actuating lever 26 is always after pressed back.

To unlock the operating lever 26 is pressed by the handle 24 to the front. In this case, the actuating lever 26 is pivoted about its pivot axis 28 relative to the bearing 27 of the actuating lever 26 to the front. The inclined surface 30 of the actuating lever 26 actuates the inclined surface 35 on the locking lever 23 and pivots the locking lever 23 to the front.

The locking hook 34 of the locking lever 23 thereby slides forwardly out of engagement with the locking lug 29 of the operating lever 26 and releases the wind deflector 17 for upward movement. The gap "X1" in Fig. 7 indicates the available game for a movement of the confirmation lever 26 and thus the wind deflector 17 upwards.

For a reduction of the wind deflector from the issued active position and a subsequent locking in the lowered rest position of the wind deflector 17 is manually (see Fig. 8) or by the closing roof part 12, the inner cover plate 40 in the front region of the lid 12 at its bottom with a Contact surface 41 off

Plastic is provided, which presses on the wind deflector 17 from above, the wind deflector 17 is pressed from its extended position down. In this case, the inclined surface 30 of the actuating lever 26 runs on the associated inclined surface 35 of the locking lever 23 and pushes it forward until the locking hook 34 of the locking lever 23 engages the locking lug 29 of the actuating lever 26 (FIG. 5).

Notwithstanding the embodiment according to FIGS. 2 to 7 in the second variant shown in FIGS. 8 to 13 show a locking device 22 which is actuated substantially in the "Z" direction, Fig. 8 shows the lowering and locking operation whereby the wind deflector is pushed down with the flat hand, the recessed handle 24A (see Figs The wind deflector 17 locks automatically in the lowermost position, the mechanics being lowered, locked in the section according to FIG

Position shown. In Fig. 11 the unlocking is shown by operating the handle 24A, the illustration already shows the issued active position of the wind deflector 17. In section according to FIG. 13, the mechanism is shown in lowered, unlocked position. The locked function shown in Fig. 10 shows a cooperating with the inclined surface 35 on the locking lever 23 functional surface -30, which is comparable in function with the inclined surface 30 of the first variant. The operation of the handle 24A takes place in the form of a pivoting movement about the pivot axis 28. It has thereby changed substantially in the direction "Z".

The handle 24A must be recessed against the bezel 25 to preclude actuation by the lid 12 and to facilitate manual operation when closing (see FIG. 8), since the handle 24A must also be unactuated here. The unlocking process according to FIGS. 10 to 12 is initiated by pushing the handle 24A in the direction of the force F (see FIG. 10), the functional surface 30 of the handle 24A actuates the locking lever 23 forward (this process is similar to the first variant), the functional surface 30 of the handle 24A pans that

Lock lever 23 comes to the pivot axis 39 forward until he ^■ to the region "x" (see Fig. 10) freely and the wind deflector 17 can be issued.

When the cover 12 is closed, there is a seal 50, which at the

Roof opening 9 facing inner edge of the cowl 3 is arranged on the lid 12 at.

By means of the locking device 22 described, the wind deflector 17 can remain in its rest position even when the cover 12 is open. However, it can also be manually transferred by lifting the lock in its issued active position. From there, in turn, a manual lowering into the rest position is possible or the cover 12 pushes the wind deflector 17 when closing from above into the locking position. It will be in the direction of the

Ausstellposition spring-loaded release lever 21 pressed down. LIST OF REFERENCE NUMBERS
