Description

Fixed roof element with guide rail and slide block

Technical Field

The present invention relates to a stationary roof element for a vehicle roof.

Background

Such fixed roof elements are known in practice and are roof elements which are part of a so-called panoramic roof and are mounted rigidly or immovably with respect to the vehicle body. The stationary roof element comprises a panel which is formed from glass sheets and is a roof skin element which thus forms the outer surface of the stationary roof element. On the underside of the glass pane, a guide rail is arranged for guiding a roller blind web of a screening system of a fixed roof element. The roller blind web is an adjustable roof element and is provided with a pull-out awning frame which is guided by means of a slider in a guide track of the guide rail. The guide rails are each configured such that the slide concerned engages into the associated guide rail from above. The side edges of the roller blind web can likewise be guided in guide tracks, wherein these side edges are each introduced from above into the guide track of the guide rail concerned. In order to be able to achieve engagement of the slider and the side edges into the guide rail, the guide rail must each have a sufficiently large constructional height. The attachment of the guide rail to the panel is carried out at a large distance from the guide rail. Furthermore, due to its design, the guide rail 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 results in a space requirement in the transverse direction of the vehicle roof, at the expense of the size of the vehicle roof see-through region which can be covered by the roller blind web. Due to the structural height and the open profile cross section, the load fed by the roller blind web can cause deformations on the guide rail, which can lead to movement difficulties or even to jamming of the slider.

Disclosure of Invention

The object of the present invention is to provide a fixed roof element of the type mentioned at the outset, the guide rails of which can be arranged as close as possible to the panel, preferably in the outermost edge region of the fixed roof element, 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 stationary roof element having the features according to the invention.

According to the invention, a stationary roof element for a vehicle roof is therefore proposed, which comprises a planar pane, on the underside of which a guide rail for an adjustable roof element is arranged, which comprises a slide guided in the guide rail. The guide rail has a closed, channel-free (in particular channel-free) upper side which is formed by a closed cover section which extends in the transverse and longitudinal direction with respect to the panel and from which at least one guide web protrudes downwards, wherein the slide rests on the guide rail from below and is guided on the guide web.

By means of the geometry of the guide rail according to the invention, the slide can run under the guide rail or be guided such that the guide rail can be attached with its upper side in the broadest sense to a panel of the face type. Thus, because the rail is mounted to the panel above the slider, there is a lower engagement (Untergriff) of the slider. Thus, the rail can be positioned very close to the panel of the face type. By guiding the slide on the guide tab projecting downward from the cover section and arranging the guide rail close to the panel, possible slight deformations of the guide rail under load and/or due to temperature effects do not lead to movement difficulties which can interfere with the actuation of the adjustable roof element and/or lead to undesirable noise generation when the slide is moved over the guide rail.

The guide rail of the stationary 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 dimensions is in particular approximately 2:1 to 5:1.

Due to the small constructional height of the guide rail and the slide block and the resulting possible close arrangement on the panel, less constructional space is required in the roof height direction, which in turn advantageously influences the head freedom of the vehicle occupants. Furthermore, due to its small constructional height, the guide rail can be adapted in a simple manner to the curvature of the panel by bending, wherein a high profile accuracy is maintained.

The cover section of the guide rail, which extends in the transverse and longitudinal directions, can be attached to the panel in the broadest sense. The additional installation space for attaching to the panel is eliminated, so that the perspective area lying next to the guide rail is also constructed to be larger than in the past.

Because of the low leverage, the loads occurring, which are input by the slide in the vertical and transverse directions, can be absorbed by the panel. Whereby deformation of the guide rail can be resisted. Difficulty of movement due to deformation and tolerance can be avoided. Furthermore, the plastic used to make the guide rail may be used with little or no reinforcement. This in turn represents a low cost for the material and for the manufacturing process.

In a preferred embodiment of the stationary roof element according to the invention, the guide tab of the guide rail has a substantially inverted T-shaped cross section, wherein the guide tab is surrounded on both sides by the slide. In particular, the sliding rail formed by the guide webs can be divided into a plurality of regions on the guide rail, whereby a stable support of the slide on the guide rail can be achieved. By surrounding the guide tab, the slider can be prevented from being skewed when the slider is moved.

The guide rail is very robust against deformation by the inverted T-shaped guide tab on which the slider is guided. The bending capability is maintained. Despite the ability to bend, the guide rail can be configured rigidly, 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 cable for the slide, the guide rail for fixing the roof element according to the invention has in a preferred embodiment a cable channel which opens downward. The cable channels extending in the rail longitudinal direction are 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 side rib of the slider which is guided from below into the cable channel of the guide rail.

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

The guide rail is preferably a plastic guide 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 rail with respect to the panel can be adapted in a simple manner. In particular, the course and orientation of the plastic rail can follow the two-dimensional curvature of the panel.

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

For example, the guide rail is an insert for the plastic molding section. In the course of the molding process for producing the plastic molding sections, the guide rail is inserted into the molding tool, bent if necessary, and attached there to the panel by the plastic material introduced into the respective mold cavity.

In order to ensure a reliable holding of the guide rail on the plastic molding section, the guide rail can have at least one anchoring rib or an anchoring groove on its upper side, which is molded together during 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 holding means, which forms at least one insert for the profiled section. The holding means comprise, for example, a clip on which the guide rail latches.

In a particular embodiment of the stationary roof element, the slide of the stationary roof element according to the invention, which runs under the guide rail, comprises a plate-shaped base and at least one upwardly directed rib which is angled and engages with the guide tab of the guide rail. The geometries of the guide rail and the slide are preferably coordinated with one another in such a way that the slide is integrated into the installation space of the guide rail with little installation space requirement. Thus, only a structural space is required in the transverse direction, which is predefined by the diameter of the cable section and by the wall thickness of the at least one upwardly directed rib. As a result, a space-optimized packaging (Package) of the slide and the rail in the vehicle roof height direction and in the vehicle roof transverse direction is achieved.

In order to avoid material accumulation and at the same time to achieve a geometrical reinforcement, the guide rail may have at least one cavity which extends in the rail 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 a screening system, wherein the slider preferably comprises a coupling element on which the roller blind web is fixed such that the lateral edges of the roller blind web are guided in guide rails. With respect to the vertical longitudinal center plane of the vehicle roof, 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 frame on the edge extending in the transverse direction of the vehicle roof, at the ends of which in each case a slider is arranged which is constructed and guided in a manner according to the invention.

In a particular embodiment of the fixed roof element according to the invention, the slider is constructed in multiple pieces, wherein the first slider part forms the drive part and the second slider part forms the guide part which engages 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 means ensure that the slider is guided correctly on the guide rail.

The first slider part may form the above-mentioned plate-shaped 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 in order to engage with the guide tab of the guide rail.

Preferably, the first and second slider parts are non-captively connected to each other. For example, the first slider part has a latching tab for this purpose, which engages with a latching counter element of the second slider part.

In order to orient the first and second slider parts precisely with respect to each other when assembled, one of the two slider parts may comprise a positioning nose which engages into a corresponding recess of the other slider part.

For attachment to the traction frame of the roller blind web, the second slider part advantageously comprises a connecting rod in an integrated manner, which is connected to the traction frame of the adjustable roof element of the roller blind web.

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 each preferably molded as a plastic injection molding.

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

Detailed Description

In the figures, a vehicle roof 10 is shown, which is embodied as a stationary vehicle roof, which is provided with a vehicle roof recess 12 in which a stationary vehicle roof element 14 is arranged. The stationary roof element 14 is immovably fixed in relation to the vehicle body in the roof recess 12 and comprises a housing element 16 which is made of composite safety glass and forms the exterior surface of the roof 10. The housing element 16 is a panel in the sense of the present invention.

The stationary roof element 14 is at least largely mirror-symmetrical with respect to a vertical roof longitudinal center plane. The description of the stationary roof element 14 follows in part only on the area arranged on the left with respect to the direction of travel of the vehicle concerned, which area is shown in fig. 2. The region arranged on the right side of the vertical roof longitudinal center plane with respect to the forward travel direction is obtained in a similar manner.

The stationary roof element 14 has a substantially rectangular see-through region 18 which can be concealed by means of a screening system 20 which comprises a roller blind web 22 as screening element or as adjustable roof element. The roller blind web 22 is guided on both sides with respect to a vertical longitudinal center plane of the vehicle roof with side edges in guide rails 24, which extend in the longitudinal direction of the vehicle roof. The roller blind web 22 is provided on its front edge arranged in the pull-out direction with a tensioning frame 26, which is guided with its ends in guide rails 24 by means of a slide 28. The roller blind web 22 is fixed to the roller 30 at its edge facing away from the canopy frame 26. By actuating 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 screening position, in which the see-through region 18 is at least partially covered by the roller blind web 22, the drive means comprising drive cables 34A and 34B, which are driven by a common drive motor 36 and are each connected to the slide 28 of the pull canopy frame 26.

The winding shaft 30 is provided with a winding spring acting in the winding direction, on which the roller blind web 22 is wound up in the case of the release of the see-through region 18, and from which the roller blind web 22 is unwound in the case of the shielding of the see-through region 18. The reel 30 is supported at its ends on respective support means 38 which are fastened on the rear side to the underside of the housing element 16 by means of the guide rail 24 concerned. The support means 38 serve on the one hand to support the reel 30 and on the other hand to center the material of the roll blind web 22 such that its edges exactly enter the respective guide rail 24.

A plastic molding section 40, which is made of polyurethane foam, is molded on the underside of the housing element 16. The Molding of the plastic Molding section 40 on the housing element 16 takes place in a foaming tool according to a foaming process or a RIM (Reaction Injection Molding) process.

As shown in fig. 3, the plastic molding sections 40, which are molded in one piece or in a plurality of pieces to the underside of the housing element 16, each receive the guide rail 24 as an insert, in such a way that the guide rails 24 are each inserted with their closed, channel-free upper side into the plastic molding sections 40. The guide rails 24 each have flanks 42 and 43, which are approximately half overlapped by the plastic molding section 40 and are configured obliquely to the main plane of the respective guide rail 24. The flanks 42 and 43 of the guide rail extend from the plastic molding section 40 toward one another. The guide rails 24 each have an anchor rib 44 on their upper side, which extends in the longitudinal direction and is configured with a undercut into which the plastic molding section 40 engages.

The guide rail 24 has in each case a cover section 46, which extends in the transverse and longitudinal direction and is plate-shaped in the broadest sense, on the upper side of which an anchor rib 44 is formed and from the lower side of which a guide web 48 protrudes downwards, which has a substantially inverted T-shaped cross section. Furthermore, two guide ribs 50 and 52 project downwardly from the cover section 46, which delimit a cable duct 54 which opens downwardly through a slot 56. The guide rib 50 and the guide tab 48 delimit a guide rail 58 which opens downward. On the side facing away from the guide rail 58, the guide webs 48 delimit, together with the flanks facing the see-through region 18, a guide rail 60 which likewise opens downward. The associated slide 28 of the pull-out canopy frame 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 member 62 and a second slider member 64, respectively. The first slider part 62 is the drive part of the slider 28, which comprises a plate-shaped base 66, to which a cable section 68 engages externally with respect to the see-through region 18, which cable section forms a side rib of the first slider part 62 and is guided into the cable channel 54 of the guide rail 24. Cable section 68 is molded onto drive cable 34A or 34B that is routed into the cable passage 54 in question. A catch 70 and a detent nose 72 are formed on the upper side of the plate-shaped base 66. The second slider part 64 is fixed and positioned on the plate-shaped base 66 of the first slider part 62 by means of a locking tab 70 and a positioning nose 72.

The second slider part 64 comprises a base 74, on which the locking tab 70 acts, and which rests on the plate-shaped base 66 of the first slider part 62. Two upwardly directed ribs 76 and 78 project from the base 74, which ribs are angled and engage the guide webs 48 of the guide rail or engage the guide rails 58 and 60 from below. The connecting rods 80 directed inwards in the transverse direction, which are connected to the canopy frame 26, engage in the ribs 76 which engage in the built-in guide rails 60.

The first and second slider parts 62, 64 are each constructed as a plastic injection-molded part.

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