Description

Fixed roof element with guide rail and slide block

Technical Field

The invention relates to a fixed roof element for a vehicle roof, comprising the features of the preamble of claim 1.

Background

Such fixed roof elements are known in practice and are roof elements which are part of a so-called panorama roof and are mounted rigidly or immovably in relation to the vehicle body. The fixed roof element comprises a surface panel which is formed by a glass pane and is a roof shell element which thus forms the outer surface of the fixed roof element. On the underside of the glass pane, guide rails are arranged for guiding a roller blind web of a screening system for fixing a roof element. The roller blind web is an adjustable roof element and is provided with a draw-off roof frame which is guided in a guide track of the guide rail by means of a slide. The guide rails are each designed such that the slide concerned engages into the associated guide rail from above. The lateral edges of the roller blind web can likewise be guided in guide tracks, wherein these lateral edges are each introduced from above into the guide tracks of the guide rail concerned. In order to be able to engage the slide and the side edges into the guide rails, the guide rails must each have a sufficiently large overall height. The attachment of the guide rail to the surface panel takes place at a large distance from the guide rail. Furthermore, the guide rail, because of its design, must be positioned at a distance from the panel in order to ensure a free passage of the slider and the roller blind web between the guide rail and the panel. This also leads to a structural space requirement in the transverse direction of the vehicle roof, which is at the expense of the size of the roof see-through region that can be covered by means of the roller blind web. Due to the height of the construction and the open profile cross section, the load applied by the roller blind web can cause deformations in the guide rails, which can lead to difficulty in movement or even to jamming of the sliding blocks.

Disclosure of Invention

The object of the present invention is to provide a fixed roof element of the type mentioned above, the guide rails of which can be arranged as close as possible and preferably in the outermost edge region of the fixed roof element on the panelling, wherein nevertheless a reliable and interference-free actuation of the adjustable roof element is ensured.

According to the invention, this object is achieved by a fixed roof element having the features of claim 1.

The invention therefore proposes a fixed roof element for a vehicle roof, comprising a planar panel, on the underside of which a guide rail for an adjustable roof element is arranged, which adjustable roof element comprises a slide guided in the guide rail. The guide rail has a closed, channel-free (in particular guide channel-free) upper side, which is formed by a, in particular closed, cover section, which extends in the transverse and longitudinal directions with respect to the panel and from which at least one guide tab projects downward, wherein the slider rests from below on the guide rail and is guided thereon.

By means of the inventive geometry of the guide rail, the slider can run or be guided under the guide rail, so that the guide rail can be attached to the floor panel with its upper side in the broadest sense. Therefore, there is an under-engagement (Untergriff) of the slider, as the guide rail is mounted to the planar panel above the slider. The guide rail can thus be positioned very close to the panel of the surface type. By guiding the slider on the guide webs projecting downward from the cover section and arranging the guide rails close to the surface panel, possible slight deformations of the guide rails under load and/or due to temperature effects do not lead to movement difficulties which can disturb the actuation of the adjustable roof element and/or lead to undesirable noise generation when the slider is moved on the guide rails.

The guide rail of the fixed roof element according to the invention preferably has a cross section whose dimension in the transverse direction is greater than the dimension in the height direction. The ratio of the dimensions is in particular about 2:1 to 5:1.

owing to the small overall height of the guide rails and the sliders and the close arrangement that is possible with these on the floor panel, less installation space is required in the direction of the roof height, which in turn advantageously affects the head freedom of the vehicle occupants. Furthermore, due to its low overall height, the guide rails can be adapted in a simple manner to the curvature of the panel by bending, wherein a high profile accuracy is maintained.

The cover sections of the guide rail, which extend in the transverse direction and in the longitudinal direction, can be attached to the floor panel in the broadest sense. The additional installation space for attachment to the surface panel is eliminated, so that the see-through area next to the guide rail is also formed to a greater extent than in previous solutions.

Due to the low leverage, the loads occurring in the vertical and transverse direction from the sliding blocks can be absorbed by the surface-type panels. Thereby resisting deformation of the guide rail. Difficulty in movement due to deformation and tolerance can be avoided. Furthermore, the plastic used for the manufacture of the guide rail may be used without or with only little reinforcement. This in turn represents a low cost for the material as well as for the manufacturing process.

In a preferred embodiment of the fixed roof element according to the invention, the guide tabs of the guide rail have a substantially inverted T-shaped cross section, wherein the guide tabs are surrounded on both sides by the sliding block. In particular, the sliding track formed by the guide webs can be divided into a plurality of regions on the guide rail, as a result of which a stable support of the slider on the guide rail can be achieved. By enclosing the guide tab, skewing of the slider can be prevented when the slider is moved.

The guide rail is very robust against deformation by the guide tabs of the inverted T shape, on which the slide is guided. The bending ability is maintained. Despite the bending capability, the guide rail can be rigidly configured, so that high tensile forces and cable loads can be absorbed and guided out into the panel.

In order to be able to guide the drive cables for the sliding blocks as well, the guide rail according to the invention for fixing the roof element has in a preferred embodiment a cable channel which is open downwards. The cable duct running in the longitudinal direction is offset from the guide webs in the transverse direction of the panel. In particular, the slider has a cable section which is attached to the drive cable and forms a lateral rib of the slider which leads from below into the cable channel of the guide rail.

In order to laterally delimit the guide region of the guide rail, it is advantageous if the guide rail fixing the roof element has side wings according to the invention, which preferably extend downward toward one another.

The rail is preferably a plastic rail. In order to achieve an economical production of the guide rail, the guide rail is preferably a plastic extrusion and in particular a two-component plastic extrusion. Due to the deformability of the plastic material or its flexibility, the orientation and orientation of the plastic guide rail with respect to the planar panel can be matched in a simple manner. In particular, the plastic guide rails can follow the two-dimensional curvature of the surface-like panel.

In a particular embodiment of the fixed roof element according to the invention, the fixing of the guide rail to the panel is effected by a plastic profiled section which is molded to the underside of the panel. The plastic molding section is preferably formed from a polyurethane foam material and is produced in a suitable molding tool or foaming tool.

For example, the guide rail is an insert of a plastic molded section. In the molding process for producing the plastic molding sections, the guide rails are therefore inserted into the molding tool, optionally bent, and attached there to the planar panel by the plastic material introduced into the respective mold cavity.

In order to ensure a secure retention of the guide rail on the plastic profiled section, the guide rail can have at least one anchoring rib or anchoring groove on its upper side, which is co-profiled in the extrusion process for producing the guide rail.

In an alternative embodiment of the fixed roof element according to the invention, the guide rail is fixed to a retaining means which forms at least one insert of the profiled section. The holding means comprise, for example, a clip on which the guide rail latches.

In a particular embodiment of the fixed roof element, the slider of the fixed roof element according to the invention, which runs under the guide rail, comprises a plate-like base part and at least one upwardly directed rib which is angled and engages with the guide tab of the guide rail. The geometry of the guide rail and the slide are preferably adapted to one another, so that the slide is integrated into the installation space of the guide rail with a small installation space requirement. In the transverse direction, therefore, for example, only a structural space is required, which is predetermined by the diameter of the cable section and by the wall thickness of the at least one upwardly directed rib. Therefore, a space-optimized packaging (Package) of the slider and the guide rail in the height direction of the vehicle roof and in the transverse direction of the vehicle roof is achieved.

In order to avoid material accumulation and at the same time to achieve a geometric reinforcement, the guide rail can have at least one cavity which extends in the longitudinal direction but has no guiding function.

In a preferred embodiment of the fixed roof element according to the invention, the adjustable roof element is a roller blind web of the shading system, wherein the slide preferably comprises a coupling element on which the roller blind web is fixed such that a side edge of the roller blind web is guided in the guide rail. In relation to the vertical roof longitudinal center plane, the stationary roof element comprises, in particular on both sides, a guide rail in which the relevant edge of the roller blind web is guided. The roller blind web is provided with a pull-out awning frame on the edge extending in the transverse direction of the vehicle roof, at the ends of which a slide block constructed and guided in the manner according to the invention is arranged in each case.

In a particular embodiment of the fixed roof element according to the invention, the slide is constructed in multiple parts, wherein the first slide part forms the drive part and the second slide part forms the guide part which engages with the guide rail. The drive component is in particular attached to a drive cable, by means of which the adjustable roof element can be driven. The guide members ensure that the slide is correctly guided on the guide rails.

The first slider part may form the above-mentioned plate-like base part, which is preferably oriented substantially parallel to the main plane of the guide rail. At least one upwardly directed rib is preferably formed on the second slider part, which rib is angled to engage with the guide tab of the guide rail.

Preferably, the first slider part and the second slider part are connected to each other in a non-loss manner. For example, the first slide part has for this purpose a catch tab which engages with a catch fitting element of the second slide part.

In order to orient the first and second slider parts precisely with respect to one another during assembly, one of the two slider parts can comprise a locating nose which engages into a corresponding recess of the other slider part.

For attachment to the pull-off roof frame of the roller blind web, it is advantageous if the second slider part comprises in one piece a connecting rod which is connected to the pull-off roof frame of the roller blind web or of the adjustable roof element.

The slider for fixing the roof element according to the invention is preferably a plastic injection-molded part. In the case of a multi-part construction of the slide, the individual slide parts are likewise preferably each molded as a plastic injection molded part.

Further advantages and advantageous configurations of the subject matter of the invention can be taken from the description, the drawings and the claims.

Detailed Description

In the figures, a vehicle roof 10 is shown, which is designed as a fixed vehicle roof provided with a roof recess 12 in which a fixed roof element 14 is arranged. The fixed roof element 14 is fixed in the roof recess 12 so as to be immovable relative to the vehicle body and comprises a housing element 16 which is made of a composite safety glass and forms the outer surface of the vehicle roof 10. In the sense of the invention, the housing element 16 is a flat panel.

The fixed roof element 14 is at least largely mirror-symmetrically configured with respect to a vertical roof longitudinal center plane. The description of the fixed roof element 14 is only made in part in the following with reference to the region arranged on the left with respect to the forward driving direction of the vehicle concerned, which region is illustrated in fig. 2. The region arranged to the right of the vertical roof longitudinal center plane with respect to the forward driving direction is obtained in a similar manner.

The fixed roof element 14 has a substantially rectangular see-through region 18 which can be concealed by means of a shading system 20 comprising a roller blind web 22 as shading element or adjustable roof element. The roller blind web 22 is guided with lateral edges on both sides with respect to a vertical roof longitudinal center plane in guide rails 24, which extend in the roof longitudinal direction. The roller blind web 22 is provided at its edge arranged to the front in the pull-out direction with a draw-off frame 26, which is guided with its ends in the guide rails 24 by means of respective sliders 28. The rolling web 22 is secured to the roller 30 at its edge facing away from the draw frame 26. By operating the drive assembly 32, the roller blind web 22 can be adjusted between a release position, in which the see-through region 18 is released, and a covering position, in which the see-through region 18 is at least partially covered by the roller blind web 22, and a covering position, in which the drive means

34A and 34B which are driven by a common drive motor 36 and are each connected to the slide blocks 28 of the pull hood 26.

The winding shaft 30 is provided with a winding spring acting in the winding direction, onto which the roller blind web 22 is wound with the see-through area 18 released and from which the roller blind web 22 is unwound with the see-through area 18 shielded. The winding shaft 30 is supported at its two ends on a respective support device 38, which is fastened on the rear side of the vehicle to the underside of the housing element 16 via the respective guide rail 24. The support device 38 serves, on the one hand, to support the winding shaft 30 and, on the other hand, to center the material of the roller blind web 22 so that its edge enters exactly into the respective guide rail 24.

On the underside of the housing element 16, a plastic molded section 40 is molded, which is made of a polyurethane foam material. The plastic Molding section 40 is molded onto the housing element 16 in a foaming tool in accordance with a foaming process or a RIM (Reaction-Injection-Molding) process.

As shown in fig. 3, the plastic molded section 38, which is molded integrally or in multiple parts to the underside of the housing element 16, receives the rails 24 in each case as an insert, to be precise in such a way that the rails 24 in each case with their closed, channel-free upper side engage in the plastic molded section 40. The guide rails 24 each have a

side wing

42 and 43, which is overlapped approximately in half by the plastic molded section 40 and is configured obliquely to the main plane of the respective guide rail 24. The

flanks

42 and 43 of the guide rails extend from the plastic-molded section 40 toward one another. The rails 24 each have on their upper side an anchoring rib 44 which extends in the longitudinal direction and is configured with an undercut into which the plastic molded section 40 engages.

The guide rails 24 each have a cover portion 46, which extends in the transverse direction and in the longitudinal direction and is plate-shaped in the broadest sense, on the upper side of which an anchoring rib 44 is formed and from the underside of which a guide tab 48 projects downward, which has a substantially inverted T-shaped cross section. Furthermore, two

guide ribs

50 and 52 project downward from the cover section 46, which delimit a cable duct 54 which opens downward through a slot 56. The guide ribs 50 and the guide webs 48 delimit a downwardly open guide track 58. On the side facing away from the guide rail 58, the guide webs 48 delimit a guide rail 60, which is likewise open downward, together with the side wings facing the see-through region 18. The relevant slide 28 of the draw-off canopy 26 is guided in the guide rails 58 and 60 or on the guide webs 48.

As shown in fig. 4 and 5, the slider 28 has a first slider part 62 and a second slider part 64, respectively. The slide part 62 is a drive part of the slide 28 and comprises a plate-shaped base 66 to which cable sections 68, which form lateral ribs of the slide part 62 and are guided into the cable channels 64 of the guide rail 24, engage externally with respect to the see-through region 18. The cable section 68 is molded onto the

drive cable

34A or 34B guided into the cable channel 54 concerned. A catch tab 70 and a locating nose 72 are formed on the upper side of the plate-like base 60. The slider part 64 is fixed and positioned on the plate-like base part 66 of the slider part 62 by means of a catch tab 70 and a positioning nose 72.

The slider part 64 comprises a base 74, on which the catch flap 70 acts and which is located on the plate-shaped base part 66 of the slider part 62. Two upwardly directed

ribs

76 and 78 project from the base 74, which ribs are angled and engage with the guide webs 48 of the guide rails or engage from below into the guide rails 58 and 60. Connecting rods 80 pointing inwards in the transverse direction, which are connected with the draw-off canopy 26, engage in ribs 76 engaging in the built-in guide rails 60.

The

slider parts

62 and 64 are each designed as plastic injection-molded parts.

The material of the roller blind web 22 attached to the pull-out awning frame 26 is also attached to the slider part 64 of the slider 28, so that the slider is guided with its side edges in the respective guide rail 24 in the respective guide track 60 concerned. The slider 28 is arranged in front of the roller blind web 22 in the pull-out direction.
