Description

Technical Field

[0001] The invention relates to an assembly for moving a cover of a vehicle roof. In addition, a guide rail for such an assembly and a vehicle roof having such an assembly are described. Background Art

[0002] Such components for vehicle roofs are widely known and are used to, starting from a closed position for closing the roof opening, first lift the cover in its rear region for opening by an unfolding mechanism and then move it backwards into an open position. DE 100 23 314 C1 describes a so-called externally guided sliding roof for this purpose. The unfolding mechanism usually moves in an extruded aluminum profile. The production of aluminum profiles is associated with a high incorporation of CO2 into the atmosphere. Summary of the invention

[0003] The object underlying the present invention is to specify an assembly for moving a cover of a vehicle roof, a guide rail and a vehicle roof which allow a reliable operation and reduce the use of CO 2 .

[0004] According to a first aspect of the invention, this object is achieved by an arrangement for moving a cover of a vehicle roof having a roof opening, wherein the cover can be deployed by means of an unfolding mechanism starting from a closed position in which the cover closes the roof opening into a ventilation position in order to be opened in the region of its rear edge and then brought into an open position, wherein the unfolding mechanism has:

[0005] - a guide rail extending lengthwise in the longitudinal direction,

[0006] - a slide which can slide on the guide rail in the longitudinal direction and is used to move the cover,

[0007] - wherein the guide rail is produced from plastic,

[0008] and has a web in which a guide slot for controlling the unfolding mechanism is formed.

[0009] Compared to a guide rail made of extruded aluminum, the construction of the guide rail from plastic saves considerable CO2, since the processing of extruded aluminum is very CO2-intensive. In order to achieve a stable guide rail rigidity, it is sensible to construct a relatively wide web, which in turn offers the possibility of integrating a slide in the web for controlling the deployment mechanism.

[0010] The deployment mechanism advantageously comprises a front deployment rod, a cover support, a rear deployment rod and a coupling rod between the slide and the rear deployment rod.

[0011] Advantageously, the movable slide is coupled to the front deployment rod, which is pivotably connected to the cover support. Advantageously, the rear deployment rod is likewise connected to the cover support, and the coupling rod is pivotably arranged on the slide and pivotably arranged on the rear deployment rod. With this mechanism, the rear deployment rod is coupled to the movable slide via the coupling rod, whereby a locking device can be completely omitted.

[0012] Advantageously, the web has a first sliding groove for controlling a first sliding groove sliding piece of the front deployment rod and a second sliding groove for controlling a second sliding groove sliding piece of the front deployment rod.

[0013] Advantageously, the rear deployment rod is also controlled by a third slide slot for controlling a third slide slot sliding piece and a fourth slide slot for controlling a fourth slide slot sliding piece.

[0014] Advantageously, the first and second slotted link sliding pieces on one side of the web are arranged in the first and second slotted links, and the third and fourth slotted link sliding pieces on the opposite side of the web are arranged in the third and fourth slotted links.

[0015] This configuration makes it possible to arrange the front deployment rod on one side of the web and the rear deployment rod with the coupling rod and the cover bracket on the opposite side of the web. This allows a compact embodiment of the assembly, since the front deployment rod is arranged on one side of the web and the rear deployment rod with the cover bracket and the coupling rod are arranged on the other side of the web of the guide rail, and the kinematics of the front deployment rod and the rear deployment rod are controlled by means of the slide rails in the corresponding slide rails in the web.

[0016] In addition, advantageously, the slide surrounds the web of the guide rail from above in an inverted U-shaped manner. Thus, it is feasible that the front deployment rod coupled with the slide can be arranged on one side, and the coupling rail that is similarly pivotably fixed on the slide can be arranged on the other side of the web.

[0017] According to another aspect of the invention, the guide rail for the assembly described above is manufactured by plastic injection molding. This has the advantage that the guide rail can also be provided with reinforcements, for example for a screw connection, or with reinforcements in the form of a honeycomb structure on the underside, thereby achieving a higher rigidity of the guide rail. Manufacturing by plastic injection molding allows the guide rail to be installed in the assembly described above without post-processing, in particular without cutting post-processing. Plastic injection molding allows undercuts, which are necessary, for example, for the construction of the slideway.

[0018] According to another aspect of the invention, the guide rail for the assembly described above is manufactured by plastic extrusion. The manufacturing cost of plastic extrusion is cheaper and, compared with extruded aluminum profiles, also achieves significant savings in CO2 usage.

[0019] In the case of guide rails produced by the plastic extrusion method, subsequent processing is necessary, in particular the introduction of sliding grooves.

[0020] Another aspect of the invention relates to a vehicle roof having an assembly as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 A vehicle 100, in particular a motor vehicle, is shown according to an embodiment. The vehicle 100 has a roof 101. A cover 103 is arranged on the roof 101. For example, the cover 103 can be moved relative to the rest of the roof 101. Thus, the roof opening 102 can be selectively closed by the cover 103 or partially opened.

[0032] The vehicle has a windshield 104. The cover 103 has a front edge 105 which, in an operationally suitable state, faces the windshield 104. A rear edge 106 of the cover 103 faces away from the windshield 104 in the longitudinal direction X.

[0033] The movement of the cover 103 is facilitated by the deployment mechanism 108 ( Figures 2 to 7 ). For example, the unfolding mechanism 108 has a guide rail 107 connected to the vehicle roof 101. For example, a drive cable is guided in the guide rail 107. For example, the drive cable contacts the electric drive motor and other components of the unfolding mechanism 108 in order to move the cover 103 relative to the rest of the vehicle roof 101.

[0034] For example, the deployment mechanism 108 is designed in the manner of a so-called externally guided sliding roof. During operation, the rear deployment rod 110 assigned to the rear edge 106 is moved together with the cover 103 relative to the rest of the roof in the opening direction. This can be different, for example, in the case of a so-called spoiler roof, in which the cover is moved relative to the rear deployment rod during opening.

[0035] The location or direction information used, such as rear or front, top or bottom, left or right, vertical or horizontal, refers to the vehicle longitudinal axis and the usual direction of travel of the vehicle 100 to be put into operation. The vehicle longitudinal axis is a horizontal axis and can be referred to as the X-axis or longitudinal direction X. The vehicle transverse axis is also a horizontal axis and can be referred to as the Y-axis or transverse direction Y. The vehicle height axis is a vertical axis and can also be referred to as the Z-axis or height direction Z. The height direction Z, the transverse direction Y and the longitudinal direction X form a Cartesian coordinate system and are each oriented perpendicular to one another, as in Figure 1 As described in .

[0036] The unfolding mechanism 108 is arranged in particular on both sides of the roof opening 102 and is of similar design in each case. Therefore, only one side is described below, and the description, features, functions and advantages also apply correspondingly to the opposite side.

[0037] Figure 2Shown is a guide rail 107 with an unfolding mechanism 108, wherein the unfolding mechanism consists of a front unfolding rod 109, a drive slide 120, a coupling rod 121 swivellably arranged on the drive slide 120, and the coupling rod is connected to the rear unfolding rod 110. The front unfolding rod 109 is connected to a cover bracket 111, which is also connected to the rear unfolding rod 110. The guide rail 107 is made of plastic, in this embodiment, it is made as a plastic injection molded part, and in particular has a web 130. In addition to the web 130, the guide rail forms a U-shaped groove 112 when viewed in cross section, wherein the web 130 forms the legs of the U-shaped groove 112. A substantially horizontal section 113 is connected to the U-shaped groove 112, in which four openings 114 are constructed to fix the guide rail 107 on the roof.

[0038] Slide grooves 131 to 134 are formed in the web 130. Figure 2 The slide plate (not visible in FIG. 1 ) is received in the slide slot again, and the slide plate is used to move the front deployment rod 109 or the rear deployment rod 110. Figure 2 As shown in FIG. 1 , the unfolding mechanism 108 is in a closed position, which means that the roof cover 103 is closed in this position of the unfolding mechanism 108 .

[0039] As already mentioned above, the guide rail 107 is manufactured as a plastic injection molded part, wherein preferably a thermoplastic such as PET, PEK, PEEK or the like is used. A so-called reinforcement 140 is formed on the guide rail, for example around the opening 114 for fastening to the vehicle roof (or on the underside in a honeycomb structure), in order to achieve the necessary dimensional stability even when constructed from plastic. The guideway 120 can be moved over a shaft 150 for the tension-compression rigid cables (not shown) by means of tension-compression rigid cables.

[0040] The movement sequence from the closed position into the ventilation position and from the ventilation position into the open position is explained in the following figures.

[0041] Figure 3 Shown in ventilation position, according to Figure 2. For this purpose, the slide 120 is slightly moved in the X direction (that is, from front to back) by a cable with tension-pressure rigidity. A coupling rod 121 is swingably arranged on the slide 120 (which surrounds the web 130 from above in a reverse U-shape), and the coupling rod is swingably connected to the rear deployment rod 110. The rear deployment rod is guided by a slide slide in the upper slide 133 and another slide slide in the lower slide 134. The movement of the slide 120 from the closed position to the ventilation position shapes the slide 133 so that the rear deployment rod 112 is deflected from a horizontal position to a substantially vertical position. For this purpose, the slide rail 133 is implemented in the X direction in the first motion section. Therefore, the cover bracket 111 (the cover is fastened to the cover bracket) also sinks in the front in the area of ​​the first deployment rod 109 and is lifted in the area of ​​the rear deployment rod 110, that is, lifted in the ventilation position.

[0042] Figure 4 Show according to Figure 2 , where the deployment mechanism is shown this time in the open position. Figure 3 In contrast, the slideway 120 is further moved backward in the X direction by the cable of tension-compression rigidity. Figure 4 The slots 131 and 132 (not visible in the figure) are deflected from the inclined position to a more vertical position by the corresponding slot slides, whereby the cover support 111, which is pivotably arranged on the front unfolding lever 109, is lifted upward (second movement section). In the third movement section, the unfolding mechanism 108 is further moved in the X direction into the open position by the tension-compression rigid cable.

[0043] Figure 5 The unfolding mechanism and the guide rail 107 are also shown in an oblique view, but from the inside of the vehicle. In this view, it is clearly visible how the drive slide 120 is connected to the coupling element 151, which can be moved by a cable with tension-compression rigidity. The coupling element 151 surrounds the guide rail on the lower side of the web 130 and is also embedded in the first slide 131. The front unfolding rod 109 is guided by two slide slides in the slides 131 and 132, wherein in the front area, the slide 132 is implemented from bottom to top (i.e., in the X direction) and the slide realizes the swinging movement of the front unfolding rod 109 from the inclined position to a more upright position. The slide 120 has a slide 122, which is implemented in a longitudinal direction in the X direction and ends with an arc segment. The front unfolding rod 109 is guided in this slide 122 by a slide slide 123. In the first movement phase, the slide 120 moves in the X direction, wherein the guide rail slide 123 moves in the guide rail 122 .

[0044] Figure 6 The following state is shown: in the state, the slide plate 123 reaches the end of the slide 122 until the slide plate transitions into the arc segment. In this movement, the front deployment rod 109 remains unchanged and is only moved by the coupling rod 121 (as previously described for Figure 2 and 3 The rear deployment rod 110 is pivoted (as described) and is pivoted via the guideways 133 and 134 and the guideway slides arranged accordingly therein from a horizontal position into a substantially vertical position.

[0045] Figure 7 Show according to Figure 6 1, wherein the slide 120 is moved to the extent that the slide rail 132 and the slide slide arranged therein (in Figure 7 The front deployment rod 109 is pivoted upwards (not visible in the figure), so that the cover support 111 is also lifted at the front and is essentially parallel to the guide rail 107. The guide rail 132 is designed to be raised in the X direction in this second movement section, which makes it possible for the lower guide slide in the straight guide 131 and the upper guide slide in the guide 132 extending obliquely upwards to pivot the front deployment rod 109.

[0046] Figure 8 Show according to Figure 7 of the view, where Figure 8 , the slide is further moved in the X direction and the unfolding mechanism 108 is therefore in the open position. The embodiment in which the guide rail 107 is made of plastic, in particular by plastic injection molding, allows the slides 131 to 134 to be integrated into the web 130 of the guide rail 107 and the unfolding mechanism can be simply designed without locking elements. In particular, the rear unfolding lever is coupled to the slide 120 via the coupling lever 121 without a rear drive slide. The rear unfolding lever 110 is coupled to the cover bracket via the receiving portion 160, which allows the rear unfolding lever to be able to move in the receiving portion 160 in a pivotable and displaceable manner.

[0047] In the shown Figures 2 to 8 In the embodiment of the present invention, the guide rail 107 is manufactured as a plastic rail by plastic injection molding.

[0048] It is also possible that the guide rail 107 is manufactured by an extrusion process, wherein no partial reinforcement 140 can be introduced and the guide rail must be thicker overall. Later, undercuts such as the guideways 131 to 134 must also be milled.

[0049] The solution according to the invention is based on the object of avoiding the extrusion of extruded aluminum rails and thus significantly reducing the introduction of CO 2 into the atmosphere. This is also achieved with extruded plastic rails.
