Description

The The present invention relates to a guide mechanism for a Cover of a sliding roof of a vehicle according to the preamble of claim 1.

Such a guide mechanism is for example from the DE 102 40 636 A1 known.

The known guide mechanism has at least one guide slot connected to the cover, between a basic position, a lowered position and a display position is movable to initiate the appropriate Deckelverstellvorgänge or to effect. The guiding scenery is along a vehicle-fixed longitudinal guide rail movable and for this purpose in the area of its front end over a front shoe mounted on the guide rail. To the vertical movements of the lid during the cover adjustment to effect, is also a movable along the guide rail rear sliding block (control slide) provided with a Sliding block (control section) with one on the guide slot cooperates with a trained slide railway. Through the longitudinal process the control slide or its control section along the slide track takes place to achieve the above positions required Pivoting of the guide slot. The front shoe forms the pivot axis.

Problematic is at a leadership mechanic the above explained Often the achievement of a sufficiently stable storage of Cover. For example, acts during the drive of the vehicle on the lid usually an upward Wind load, which depends of the driving speed and the vehicle geometry (roof contour) can assume high values. Such wind load forces must reach the maximum Driving speed reliable from the used guide mechanism be recorded. Mostly for acoustic reasons only certain, relatively small cover deflections are allowed often activities to stiffen mechanical components in the roof area be what an increase the cost entails.

It It is an object of the present invention to provide a guide mechanism of the type mentioned above with regard to the stability of the cover storage improve.

These Task is solved through a guide mechanism according to claim 1. The dependent claims relate to advantageous developments of the invention.

The inventive guide mechanism is characterized in that viewed in the longitudinal direction behind the control section of the control slide on with the control slide mitfahrender locking portion is provided, which in the closed position the lid so form-fitting cooperates with a locking counterpart portion of the guide slot, that the lid is thus supported in the vertical direction.

The The present inventors have recognized that the lid supporting the guide link considered as a pivotable about a front bearing point lever can, which in the known constructions mechanically more or less unfavorable with the vehicle-fixed guide rail is coupled. In the known constructions results poor "support ratio" with regard to the position of the bearing points in the guide rail for storing the guide link in relation to to the guide course length or Cover length.

The The basic idea of the invention is, at least for the closed position the lid an additional support to provide the lid in the vertical direction, even with comparatively simple design a considerable increase the support stability allows. The latter is according to the invention realized by that as a positive connection between the locking portion and The support caused the locking counter section viewed in the longitudinal direction behind the control section of the control slide is provided. By this arrangement on the "long Lever arm "results even with simple training of additional support components a particularly effective support. It can comparatively large Torques are recorded.

In a preferred embodiment is provided that the positive connection the lid against a supported above vertical movement. This can be advantageous while the ride upwards wind load forces are absorbed.

alternative or additionally can also be provided that the positive connection the lid against a supported downward vertical movement.

A embodiment, in which the positive connection supports the lid in both vertical directions has special advantages. This is especially occurring while driving dynamic inertial forces worn, which can act in both directions (up and down).

In a preferred embodiment the support achieved by the positive connection is essentially free of play. In this case, high demands on shape and position tolerances of the relevant To avoid components, there are various possibilities. For example may be at least one of locking portion and locking counter portion more or less elastic (eg made of plastic or with a Plastic coating or coating) may be formed. alternative or additionally may be the locking portion and / or the locking counter portion (in a front and / or rear area) have an inclined surface, to ensure the backlash of the positive connection in the closed position of the lid.

What the design of the leadership backdrop As far as this is concerned, it can - apart from that from the arrangement of the to the additional support provided locking portion - formed in a conventional manner be.

The guide slot can z. As in the prior art according to the above-mentioned DE 102 40 636 A1 be mounted in its front end by means of a sliding longitudinally movable on the guide rail, wherein the sliding block simultaneously forms the pivot bearing, ie with respect to the vehicle-fixed guide rail is pivotable within certain limits (to allow the lowering and Ausstellvorgänge the lid). Alternatively, the guide slot can be connected in its front area via a pivoting connection permitting the required pivoting operations (eg pivot bearing pins) to a front slide (sliding block) which can be moved along the guide rail.

The drive for the Verschwenkungsvorgänge the lid is done by the interaction of the control section of the control slide with the slide track of the guide link. In this regard, it should be noted that both an embodiment with a control section and an associated slide track is conceivable (cf. DE 102 40 636 A1 ), as well as a version with several control sections and accordingly more slide tracks. In the embodiment described in detail below, the control carriage has z. B. two control sections, which cooperate with two associated slide tracks.

What the design of the slide tracks) and the one or more control sections As far as that is concerned, this may also be the case advantageously resorted to known constructions become. A slide track can z. B. as a lateral groove or through Slot be formed. Alternatively or additionally, the slide track be defined by a lateral projection on the guide slot. Depending on the specific design of the slide track then results in a suitable design of the control section. For example, at designed as a slot slide track of the control section by a laterally projecting from the control slide and in the Slot engaging pin or sliding block be formed.

In an embodiment it is provided that the locking portion at least one horizontal stop surface for cooperation with the locking counterpart, which side of the guide slot is formed projecting. A longitudinally viewed front or rear end of this horizontal abutment surface is according to a preferred embodiment slight inclined (oblique surface) to a "running in a substantially play-free positive locking. "Alternatively or additionally the locking counterpart in its front and / or rear Area have a corresponding inclined surface.

Of the with the control slide moving locking section can z. B. on one side of a Führungsungskulissenkorpus be arranged.

In another embodiment it is provided that the locking portion twice, namely on both sides the guidance, is provided and with a corresponding to both sides of the guide slot provided locking counterpart section cooperates.

A suitable design of the locking portion and the corresponding Locking counter section results in practice depending on the available space and the desired power transmission capacity. In a bilateral Locking can basically transfer more power become.

The one or more locking counterparts z. B. may be provided in each case in the form of a "catch nose" projecting laterally (on one or both sides of the guide slot). The locking counterpart z. B. by an additional part (eg riveted rotary part) or by integral integration on the guide slot (eg., Gating, issued sheet metal tab, etc.) are shown. If a guide block body comprises two metal sheets laid one on top of the other, then catch noses serving as mutual locking counterpart sections can e.g. B. formed by mutually flared sheet metal tabs, which are viewed in the longitudinal direction at the same position. However, if z. B. a Führungsungskulissenkorpus is provided with a single metal sheet, it is provided according to an advantageous embodiment that mutual locking sections or catch noses like which are realized by issued in both lateral directions sheet metal tabs, which are then viewed in the longitudinal direction offset from each other (one behind the other) are arranged. In the latter case, the locking sections arranged on either side of the guide block body are correspondingly designed (offset), so that both locking sections simultaneously engage with the locking opposing sections (and at the same time come out of engagement).

In a preferred embodiment it is provided that the locking portion and the locking counter portion are formed such that they get out of the positive connection immediately after the control slide its the closed position has left corresponding position along the guide rail. In this case, the additional takes place cover support only for the "zero position" (= closed position of the lid). The term "immediate after "should, at least include the case in which the positive engagement is canceled at the latest when the control slide starting from its zero position 20% of the complete lid lowering or 20% of the total Cover exhibition required slide travel traveled Has.

At usual Constructions for A sliding roofs moves the control slide from the zero position in both directions, d. H. for the Ventilation position in usually forward and for the opening the roof usually to the rear. A forward and backward open designed locking section or such a pair of locking sections guaranteed in a simple way that the cooperating locking counter-element immediately after leaving the carriage zero position out of engagement arrives. The concrete geometry of the locking section and of the locking counterpart can be dependent from the leadership and control slide movement are designed so that the locking portion during the Do not move with the guidance collided.

at all embodiments The invention results in that a favorable "support ratio" of the additional Cover support, as the locking portion viewed in the longitudinal direction behind the Control section is arranged (located at multiple control sections the locking section behind all control sections). The additional support thus takes place on a "longer lever arm" than that conventionally realized solely by the control section (or the control sections) Cover support.

Regarding such a favorable one Abstützverhältnisses is according to one preferred embodiment provided that the horizontal distance between a front Position of the guide slot on the guide rail and the locking portion in the closed position of the lid at least 110%, preferably at least 120%, of the horizontal distance between the front storage location and the control section (or the rearmost Control section, if several control sections are provided) of the tax sled.

It It should be noted, however, that the specific arrangement geometry, in particular a favorable arrangement the locking portion of the overall construction of the relevant Sliding roofs depends. In any case, capable of according to the invention provided additional support forces acting on the lid more or less directly from the cover via the guide slot, whose locking counterpart and to transfer the locking portion in the guide rail. This can in particular a lower deflection of the lid under Wind load can be achieved.

In an embodiment is provided that the locking portion directly on the control slide is provided, for. B. as one or more horizontal abutment surfaces of already described above type. In a variant, the locking portion z. B. molded directly onto a drive cable (made of plastic) or attached, which serves to drive the control slide and in conventional Way in a cable channel of the guide rail running.

In a further development of the invention it is provided that the control slide is modularly formed from a front, the control section having slide module and a rear, the locking portion having slide module. This results z. B. a particular logistical advantage, which is that the same in principle the same guide mechanism can be installed either with or without the rear slide module in a vehicle roof. Thus, advantageously, the additional costs associated with the additional support can be expended, for example, specifically only for those vehicle roofs in which the additional support is required (eg, in the case of particularly heavy and / or large-area, in particular very long, lids). The locking portion can then be provided by adding the rear carriage module, if this z. B. makes sense by the expected wind load. The rear carriage module can, for. B. may be formed as a "Abstützbock", which is connected to the front carriage module z. B. can be introduced by hanging in the guide rail. The locking counter-element, for. As a catch nose on the guide circuit is usually only minor Mehrkos cause (if any). It can therefore always be available regardless of the version (with or without rear slide module).

1 shows a guide mechanism 10 for a lid 12 a sliding roof of a vehicle. In the illustrated closed position of the lid 12 this closes a roof opening, which towards the front through a fixed roof section 14 is limited.

Starting from this closed position, the lid 12 by means of the guide mechanism 10 lowered and moved back into an open position or be issued with its trailing edge upwards in a ventilation position.

The guide mechanism 10 includes one with the lid 12 firmly connected and thus serving as a lid carrier guide slot 16 with substantially longitudinal slide tracks 18-1 and 18-2 , In the area of its front end (not shown) is the guide slot 16 in a conventional manner by means of a front shoe longitudinally movable and slightly pivotable about a transverse axis on a vehicle-mounted longitudinal guide rail 20 stored ("front storage location"). In the back, in 1 apparent area of the guide rail 16 results in a "rear bearing point" by the engagement of trained as a bolt sliding blocks 22-1 and 22-2 in the slot-shaped slide tracks 18-1 and 18-2 ,

The sliding stones 22-1 and 22-2 stand sideways from a control slide 24 driven by an unillustrated drive cable along the guide rail 20 can be moved to the vertical movements or pivoting of the guide slot 16 and thus the lid 12 to effect in the lid adjustment.

In the illustrated embodiment, the carriage 24 modular from a front slide module 24-1 and a rear carriage module 24-2 formed, which in driving connection with the front carriage module 24-1 stands.

2 illustrates the leadership mechanics 10 after a shift of the tax sled 24 Forward. As can be seen from the figure, the link control has a pivoting of the guide slot 16 and thus the lid 12 in a ventilation position causes, in which the lid 12 with its trailing edge turned up.

3 illustrates the leadership mechanics 10 after a shift of the carriage 24 a little way back. This carriage position leads as shown to a lowering of the lid 12 how they z. B. at the beginning of a roof opening operation is passed to the lid 12 then back under the fixed roof section 14 to move (with a further displacement of the carriage 24 to the rear).

The guide mechanism 10 is on both sides of the lid 12 formed substantially identical, which is why in the figures, the guide mechanism 10 only shown for one side of the vehicle.

4 shows the guide mechanism 10 (the left side of the vehicle) in "zero position", ie for the closed position of the lid 12 , The representation of 4 thus corresponds to the situation according to 1 , The lid 12 is in 4 (as well as the 5 and 6 ) omitted the view of the components of the guide mechanism 10 to improve.

5 is a corresponding perspective view of the guide mechanism 10 after a shift of the carriage 24 to the rear (lowered lid position, approximately corresponding 3 ).

6 shows the guide mechanism 10 In contrast, when moved forward from the zero position out carriage 24 (similar 2 ). In this situation, the trailing edge of the lid is exposed upwards (ventilation position).

A peculiarity in the 1 to 6 illustrated guide mechanism 10 is that for the closed position of the lid 12 (see. 1 and 4 ) in addition to that of the slotted guide of the components 18-1 . 18-2 . 22-1 . 22-2 and 24 trained "rear bearing point" of the guide slot 16 another support of the guide slot 16 and thus the lid 12 is realized, by means of which, in particular occurring during driving dynamic loads on the lid 12 , including driving wind forces, particularly efficient in the guide rail 20 be directed.

For this purpose, viewed in the longitudinal direction behind the sliding blocks 22-1 and 22-2 on the sledge 24 (here: at the rear slide module 24-2 ) arranged locking portion 30 provided in the closed position ( 1 and 4 ) of the lid 12 such a positive fit with a locking counterpart 32 the guide scenery 16 cooperates that the lid 12 so that it is supported in the vertical direction.

In the illustrated embodiment, the locking portion comprises 30 an upper support tab 30-1 and a lower support tab 30-2 , whose clear distance (in the vertical direction) is dimensioned such that when the lid is closed (see. 1 and 4 ) formed as a catch nose locking counterpart 32 is recorded in the vertical direction without play between the two tabs. As it is from the 1 and 4 becomes clear, in this situation, an additional support of the guide slot 16 at a position considered in the longitudinal direction, for a particularly stable bearing of the guide slot 16 and thus the lid 12 is cheap (relatively far back).

If starting from this zero position according to 1 and 4 the sled 24 and thus also the locking portion 30 with the two support tabs 30-1 and 30-2 to be moved forward (lid exhibition), so the catch nose 32 released as from the 2 and 6 seen.

Even if the sled 24 starting from the zero position is moved backwards (cover lowering), the catch nose 32 released as it is from the 3 and 5 is apparent.

To the catch nose 32 smooth and reliable, as far as possible without play in the supporting engagement between the two support tabs 30-1 and 30-2 To bring, it is first advantageous if at least one of the tabs 30-1 and 30-2 , In the illustrated embodiment, the lower flap 30-2 , front and rear has a beveled course (inclined to the horizontal).

With regard to the play-free support in the engaged state, it is also advantageous if the catch nose 32 as shown has a rounded shape. In the illustrated embodiment, the cross section of the catch nose 32 oval. This catch nose shape was replaced by a corresponding encapsulation of a laterally issued sheet metal tab of the guide slot 16 formed with a plastic material.

at The following description of further embodiments are for the same effect Components used the same reference numbers, each supplemented by a small letter to distinguish the embodiment. there is essentially only on the differences to the or already described embodiments received and otherwise hereby expressly refer to the description of previous embodiments.
