Abstract
Description
[0001] A method for manufacturing a drive cable bracket for a vehicle roof is specified. Furthermore, a component for a vehicle roof having a drive cable bracket is specified.
[0002] A motor vehicle may have a roof opening that can be closed and at least partially opened by means of a movable cover. For example, the movement of the cover is driven by a drive coupled to the cover by a drive cable. It is also possible to provide a roller blind in a motor vehicle that can be moved by means of a drive and a drive cable. The drive cable is guided, for example, in a guide tube, as described in DE 101 44 742 A1.
[0003] DE 10 2018 110 124 A1 relates to a method for producing a drive cable holder for a vehicle roof for providing a component for the vehicle roof. The component is positioned in a mold. A guide tube for a drive cable is provided. The guide tube is positioned in the mold. In particular, the guide tube and the component are positioned relative to one another and relative to the mold so that predetermined positions are achieved. A plastic is introduced into the mold. In the mold, the plastic completely surrounds the drive cable radially, at least in sections. The plastic comes into contact with a surface of the component in the mold. This forms the drive cable holder, which is fastened to the component. In particular, the drive cable holder is formed after the plastic has cured.
[0004] DE 100 17 169 A1 relates to a vehicle roof cover comprising a cover plate, a molded-on or foamed plastic frame surrounding the edge of the cover plate, and an edge gap seal on the outer edge of the plastic frame. The invention further relates to a method for producing such a cover.
[0005] DE 101 64 508 A1 relates to an opening vehicle roof with an adjustable element for selectively closing or at least partially uncovering a roof opening by means of at least one rigid drive cable driven by a drive, as well as a support frame for the adjustable element that can be mounted securely to the body and in which each drive cable is routed. Each drive cable is routed in a channel pipe that is foamed into the support frame.
[0006] DE 200 06 330 U1 relates to a glass pane with a plastic border, in particular with a foamed frame made of PU foam, and an edge seal with a sealing cord, characterized in that an undercut groove is formed in the plastic border, aligned substantially perpendicular to the main surface of the glass pane, into which the sealing cord can be pressed.
[0007] DE 10 2015 119 405 A1 relates to a sunroof module comprising a cross member on which a drive device is arranged, at least one guide rail on which at least one guide contour for an adjustment mechanism is provided, and at least one drive cable extending from the cross member into the guide rail. The invention further relates to a method for producing a sunroof module.
[0008] It is desirable to provide a method for manufacturing a drive cable bracket for a vehicle roof that is simple to manufacture with a good degree of integration. It is also desirable to provide a component for a vehicle roof that includes a drive cable bracket, the component being cost-effective and relatively easy to manufacture.
[0009] According to one aspect, a method for manufacturing a drive cable mount for a vehicle roof of a vehicle is disclosed. The method comprises the following steps: - Providing a component for the vehicle roof, - Positioning the component in a mold, - Providing a guide tube for a drive cable for operating a shading system of the vehicle, wherein the guide tube has a longitudinal slot or a perforation for a longitudinal slot, - Positioning the guide tube in the mold, - Inserting a plastic into the mold so that -- the plastic material at least partially surrounds the guide tube, whereby penetration of the plastic material via the longitudinal slot into the guide tube or surrounding the guide tube (112) in the area of the perforation is prevented, and -- the plastic is firmly bonded to a surface of the component, and thus - Forming the drive cable bracket that is attached to the component, especially when the plastic has cured.
[0010] The process enables the guide tube to be directly connected to the component. Additional fastening elements such as rivets, screws, or adhesive bonds are no longer required. Subsequent insertion of the guide tube into a formed channel is no longer necessary. Furthermore, only a few process steps are required. Compared to conventional manufacturing processes, in which the guide tube is subsequently attached to injection-molded plastic parts, process steps and thus costs are saved. Furthermore, no tools are required that are traditionally needed to insert the tubes into the plastic part. The drive cable holder is also more space-saving than conventional plastic parts. Furthermore, the drive cable holder requires a comparatively small amount of space and offers particularly good insulation against running noise from a drive cable moving in the guide tube.A compact installation space for the drive components can also be achieved. This allows for increased visibility, for example, in a transparent vehicle roof.
[0011] It is particularly important to note that the guide tube is already slotted before the drive cable bracket is formed. The longitudinal slot extends over a section of the guide tube and not necessarily over the entire length of the tube. During production of the drive cable bracket, the longitudinal slot is suitably covered, sealed or closed before the plastic is introduced into the interior of the guide tube. For example, the guide tube is positioned accordingly and the shape of the mold is designed accordingly so that a wall of the mold covers the longitudinal slot. Alternatively or additionally, the mold has a projection which penetrates through the longitudinal slot into the guide tube during production and thus protects the longitudinal slot from penetration by the plastic. Alternatively or additionally, sealing elements or the like are provided to prevent the plastic from penetrating the guide tube.
[0012] Alternatively, a perforation for a longitudinal slot is provided, allowing the longitudinal slot to be added particularly easily later. This eliminates the need for special measures to seal the guide tube during production. Perforation is defined as a weakening of the material that allows for easy opening of the tube and / or insertion of the slot.
[0013] For example, this involves point-like or continuous material weakening along the longitudinal / extension direction. For example, one or more notches are provided along the extension direction.
[0014] After manufacturing the drive cable bracket, the longitudinal slot is directly accessible or can be easily added later. This eliminates the need for time-consuming subsequent slotting or removal of auxiliary components. The manufacturing process for a drive cable bracket with a slotted guide tube is thus particularly efficient and resource-saving.
[0015] The longitudinal slot is provided, for example, to connect a drive cable in the guide tube to a movable element, such as a carriage or glider slidably guided in a guide rail. This allows the movable element to be directly coupled and moved. For example, it can be used to operate a shading system, such as a sun protection roller blind, to shade a glass cover or fixed glass element.
[0016] A material-to-material bond is formed between the plastic and the component to secure the drive cable bracket to the component. Specifically, the plastic is introduced into the mold in such a way that the material-to-material bond is formed. This eliminates the need for additional mechanical connections to hold the drive cable bracket to the component.
[0017] The drive cable bracket can simultaneously serve as a frame, surround, and / or connection of the component to the vehicle or vehicle roof. For this purpose, the drive cable bracket features, for example, mounts and / or fastening elements integrated during production. This allows for the elimination of additional components by integrating the connection and representation of the required drive elements into the existing manufacturing process.
[0018] For example, the guide tube is almost entirely surrounded by plastic, at least with the exception of the area where the longitudinal slot or perforation is located. Since the longitudinal slot or perforation extends only over a small circumferential area of the guide tube, i.e., has a small width or opening in the circumferential direction, the guide tube is nevertheless sufficiently surrounded by plastic in the area of the longitudinal slot or perforation. For example, the plastic encloses the guide tube by at least 180°, approximately 270°, so that the tube is securely held.
[0019] The component is, for example, a fixed glass element. In this case, the drive cable bracket and the guide tube are directly and firmly bonded to the fixed glass element. Alternatively, the component is a frame element or several frame elements firmly connected to one another.
[0020] The mold, for example, is made up of two mold parts or halves into which the aforementioned components are inserted and positioned. The mold is then closed, for example, and the plastic is introduced. After the plastic has cured, the mold is opened, and the component, including the drive cable holder, is demolded and removed.
[0021] Where reference is made to the longitudinal slit below, this refers to the perforation for the longitudinal slit, where applicable.
[0022] According to at least one embodiment, the method comprises: providing a holding element in the molding tool for holding the guide tube on one side, in particular from a side facing away from the component.
[0023] Before the plastic is introduced, the guide tube is held, i.e. during positioning, the position of the guide tube is fixed by means of a holding element. One-sided fixation means that the guide tube is only held on one side by a holding element. A further holding element is therefore not required to hold the guide tube from the other side. In other words, one holding element is provided in the mold, which alone is sufficient to hold the guide tube in a specific area within the mold. The holding element is provided in particular on a side of the mold facing away from the component. Multiple holding elements can also be provided, each holding the guide tube on one side at specific points in the mold at intervals from one another. The guide tube is freely accessible in the mold between the holding elements.Consequently, in the areas outside the holding elements, the guide tube can be more comprehensively surrounded by the plastic, up to and including complete surrounding with the exception of the longitudinal slot or perforation. At the holding elements, the guide tube is not completely surrounded by the plastic, but only partially. The described embodiment is particularly advantageous when the component is a solid glass element. In such a case, a holding element for holding the tube from a second side would either have to remain in the component after the plastic has been introduced, or this holding element would have to protrude through the component in order to be able to be subsequently removed from the component.In both cases, the visual impression of the typically transparent solid glass element would be significantly disturbed and unacceptable for a customer, not to mention the possible mechanical weaknesses that could result, in the worst case, in glass breakage.
[0024] According to at least one embodiment, the method comprises: - Removal of the retaining element after the plastic has been inserted, and thereby - Forming a free access to the guide tube at a position of the drive cable holder corresponding to the holding element.
[0025] The retaining element is removed after the plastic has been inserted. This creates free access to the guide tube at a position on the drive cable holder that corresponds to the retaining element. This maintains free access without negatively impacting the stability of the drive cable holder. The retaining element is designed, for example, conical or funnel-shaped. The free access is therefore formed as a negative after demolding the component, i.e., approximately funnel-shaped.
[0026] According to at least one embodiment, the method comprises: - when inserting the plastic, at least partially embedding the holding element with the plastic, and thereby - The retaining element (107) remains in the manufactured drive cable holder.
[0027] In this embodiment, the retaining element(s) remain in the drive cable holder, eliminating the need for further steps, such as removing them. Due to their single-sided arrangement on the side facing away from the component, the retaining elements are not obtrusive. In particular, they can be covered by a panel, such as an interior headliner.
[0028] According to at least one embodiment, the retaining element is a clip or locking element or an adhesive tape. During or after positioning the guide tube, before inserting the plastic, the clip or locking element locks into the tube. The retaining element has a corresponding shape and / or material, such as an undercut. Alternatively, the retaining element is an adhesive tape, such as double-sided adhesive tape, so that it can be fixed in the mold and maintain the position of the guide tube until the plastic is finally inserted into the mold.
[0029] According to at least one embodiment, the molding tool has an integral holding element designed to hold the guide tube on one side, in particular from a side facing away from the component. The method comprises: - Removing the mold with the integral holding element after the plastic has been introduced into the mold, and thereby - Forming a free access to the guide tube at a position of the drive cable holder corresponding to the integral holding element.
[0030] Thus, the mold itself has a corresponding retaining element, which is removed during demolding. Otherwise, the above applies analogously.
[0031] Combinations of the above-described holding element designs are also conceivable. For example, different holding elements can be used.
[0032] According to at least one embodiment, the drive cable holder is designed like a frame and has a longitudinal frame section that runs along a vehicle's longitudinal direction when the drive cable holder is properly installed and that is assigned to a guide rail for the shading system, wherein the longitudinal slot or perforation is formed along the longitudinal frame section. A direct coupling to the guide rail or a drive element displaceable in the guide rail, such as the aforementioned slider or carriage, can thus be achieved via the longitudinal slot. The drive cable holder is thus a one-piece frame of the component. The frame runs, for example, completely or partially along the component in an edge region of the component, for example around a roof opening in the vehicle roof when the component is properly installed.For example, the drive cable bracket has one or more receptacles that are created by the molding tool during production of the drive cable bracket. Alternatively or additionally, one or more fastening elements are positioned in the molding tool and, after the plastic has been introduced, are surrounded and held by plastic. The receptacles and / or fastening elements serve, for example, to couple the component to the guide rail. The frame can also serve to connect the component, such as the fixed glass element, to the vehicle; additional receptacles and / or fastening elements can be provided for this purpose, as mentioned above. The drive cable bracket thus enables a multifunctional, one-piece element.
[0033] According to at least one embodiment, after the drive cable bracket has been manufactured, a guide rail for a shading system of the vehicle roof is attached to the drive cable bracket in the longitudinal frame section. The guide rail is thus mounted directly on the drive cable bracket, with the longitudinal slot or perforation being open / directed toward or accessible from the guide rail, in particular toward a guide rail channel. This enables a direct connection of a slider / carriage to a drive cable in the guide tube for driving the slider / carriage and thus for operating the shading system.
[0034] According to at least one embodiment, the drive cable holder has a transverse frame section that runs transversely to a vehicle longitudinal direction when the drive cable holder is properly installed in the vehicle and is formed integrally with the longitudinal section. The one-piece drive cable holder thus has two sections that seamlessly merge into one another. The guide tube, for example, also runs in the transverse frame section. The transverse frame section is designed, for example, as a feed area for the drive cable from an electric drive to the longitudinal section and thus to the guide rail.
[0035] According to one embodiment, a holder for a drive is provided. The holder is positioned in the mold before the plastic is introduced. The plastic is introduced into the mold so that the plastic holds the holder once the drive holder is formed. The holder is positioned in particular relative to the component and the guide tube at a predetermined position at which the drive is to be mounted in the finished drive cable holder. The drive is, for example, an electric drive and has, for example, an electric motor. In the ready-to-use state, the electric motor is in particular in contact with a drive cable guided in the guide tube such that the drive can move the guide cable along the guide tube. Alternatively, the holder is manufactured as a one-piece, integral component of the drive cable holder.Thus, an interface for mounting the drive is integrated into the drive cable holder.
[0036] According to at least one embodiment, a plurality of guide tubes is provided, each configured to guide a drive cable. The majority of guide tubes is positioned in the mold. The above applies analogously. For example, the guide tubes are positioned next to and / or above one another in different planes. The planes are spaced apart from one another parallel to a main extension direction of the guide tubes. In particular, the guide tubes are arranged vertically relative to one another in the different planes in the ready-to-use state. This allows for a small installation space requirement for the drive cable holder. Furthermore, a close spacing of the guide tubes from one another is possible.
[0037] According to at least one embodiment, the guide tubes are positioned in the mold at least partially overlapping. This allows the guide tubes to be crossed and arranged one above the other. This results in a reduced installation space requirement for the drive cable holder.
[0038] According to at least one embodiment, the drive cable is provided. The drive cable is inserted into the guide tube after the drive cable holder has been formed. It is possible to first form the drive cable holder on the component, which has the guide tube or multiple guide tubes. The drive cable or multiple drive cables can subsequently be easily inserted into the respective guide tubes.
[0039] According to at least one embodiment, the formation of the drive cable holder comprises a foaming process. In particular, the plastic is foamed against the mold. The plastic is, for example, a polyurethane. The guide tube is foamed around the plastic in the mold. For example, a so-called RIM process (Reaction Injection Molding) or another low-pressure process is used. For example, two different components, such as isocyanate and polyol, are introduced in liquid form into a countercurrent mixing head, homogenized, and introduced into the mold under low pressure, for example up to a maximum of 6 bar. There, the components react to form polyurethane. Due to the low pressure used in the foaming process, the guide tube is not deformed. The guide tube is, for example, a plastic pipe.This makes it possible to use a flexible, relatively thin-walled guide tube. The low internal pressures in the mold prevent the guide tube from yielding and deforming during the formation of the drive cable bracket.
[0040] According to a further aspect, a component for a vehicle roof of a vehicle is disclosed, comprising a drive cable mount according to one of the previously described embodiments. The embodiments, features, and advantages explained for the method also apply to the component, and vice versa. The component essentially enables the aforementioned advantages and functions.
[0041] According to a further aspect, a component for a vehicle roof with a drive cable holder is disclosed. The drive cable holder has a holding body made of a plastic. The drive cable holder has a guide tube that is at least partially embedded in the holding body. The holding body is formed in one piece and is integrally connected to the component. The holding body has a transverse part that runs transversely to a vehicle longitudinal direction when the drive cable holder is installed as intended in the vehicle. The transverse part has a first profile that forms a receptacle for one or more components of a shading system, in particular for receiving a vehicle interior headliner.
[0042] The embodiments, features, and advantages explained for the method also apply to the component, and vice versa. The component is manufactured analogously to the above-mentioned method. The component essentially enables the aforementioned advantages and functions.
[0043] The component with the directly molded retaining body allows for a comparatively small installation space while providing reliable support for the guide tube. Furthermore, the position of the guide tube relative to the component can be flexibly configured. No additional fastening elements are required to attach the drive cable holder to the component. This allows for a high degree of integration.
[0044] In particular, the component is advantageously provided with one or more receptacles for the shading system directly in the manufacturing process of the drive cable holder. Such receptacles are therefore an integral part of the drive cable holder. In particular, they are receptacles that enable the components to be connected to the drive cable holder. In other words, a receptacle is a special shape of the holding body for attaching a component such as the vehicle interior roof liner. For example, attachment takes place with a positive fit, for example by locking, wherein in particular no additional fastening elements are provided. For example, a vehicle interior roof liner for covering a roof opening in the vehicle roof can be easily mounted in the receptacle or receptacles. Additionally or alternatively, a receptacle can be provided as a storage space, for example for a tension bow.Additionally or alternatively, a holder can be designed as a guide channel or guide rail in or on which a component of the shading system can slide.
[0045] The cross member can be the cross section mentioned above or a separate element. The cross member can be a crosspiece or a cross member. The cross member can be part of a frame that is attached to the component, in particular, foamed onto it.
[0046] According to at least one embodiment, the drive cable holder is frame-like and has a longitudinal frame section that runs along a vehicle longitudinal direction when the drive cable holder is installed as intended. The longitudinal frame section is formed integrally with the transverse part. A guide rail for a shading system of the vehicle roof is attached to the drive cable holder in the longitudinal frame section. The guide tube has a longitudinal slot or perforation in the longitudinal frame section, which is assigned to the guide rail and is freely accessible, i.e., open to the outside or towards the guide rail. The guide rail has a second profile that forms a receptacle for one or more components of a shading system.
[0047] According to at least one embodiment, the first profile of the cross member and the second profile of the guide rail merge into one another, particularly with regard to the shape of the receptacles. In other words, the profiles are aligned and / or flush. In yet other words, the profiles merge "seamlessly."
[0048] According to at least one embodiment, the holding body has a transverse frame section that runs transversely to a vehicle longitudinal direction when the drive cable holder is properly installed in the vehicle and is formed integrally with the longitudinal frame section. The guide tube is at least partially embedded in the transverse frame section. A holder for a drive of the shading system is formed in the transverse frame section. The transverse frame section is thus also formed integrally with the transverse part.
[0049] According to at least one embodiment, the component is a frame element, a plurality of connected frame elements or a fixed glass element for a roof opening of the vehicle roof.
[0050] According to at least one embodiment, the holding body is designed to be elastic such that the drive cable holder has a head injury factor of less than 1500. In particular, the use of a PUR foam makes it possible to design the holding body with an elastic, energy-absorbing hardness, so that the holding body made of the plastic foam acts as an absorber. Thus, a head injury factor of less than 1500 is achievable in the vehicle roof area. The head injury factor (HIC, Head Injury Criterion) is, for example, prescribed by law. For example, it is possible to enable a head injury factor of less than 1000 using the holding body made of foamed plastic. Thus, the drive cable holder serves both to hold the guide tube and, if applicable, the drive, and also as an absorber to enable the required head injury factor in the vehicle roof area.This eliminates the need for additional absorber foam components, reducing assembly and component costs. Furthermore, a high degree of integration is achieved.
[0051] The above-mentioned refinements with regard to the process and component apply analogously. For example, multiple guide tubes can be provided.
[0052] Further advantages, features, and developments will become apparent from the following exemplary embodiments explained in conjunction with the figures. Identical, similar, or functionally identical elements may be provided with the same reference numerals throughout the figures. They show: Fig. 1 a schematic representation of a component according to an embodiment, and Fig. 2 to 7 schematic sectional views of the component.
[0053] Fig. Figure 1 shows a component 100 for a vehicle roof of a motor vehicle according to an exemplary embodiment of the invention. Component 100 is a fixed glass element that is inserted into a roof opening of the vehicle roof. Component 100 can also be a single- or multi-part roof frame element, for example, made of plastic or a metal such as a sheet metal part.
[0054] The component 100 has a drive cable holder 101, which is formed in one piece and foamed directly onto a surface 102 of the component 100. The drive cable holder 100 has a plastic holding body 103. The holding body 103 is made of polyurethane, for example. The holding body 103 is integrally connected to the component 100.
[0055] The component 100 has a shading system 104, which—in a properly installed state—is arranged on the component 100 in the region of a front side 106 of the component 100 relative to a vehicle longitudinal direction 105 (X-direction, also longitudinal direction) of a vehicle. The shading system 104 is, for example, a roller blind arrangement for shading the component 100 and has corresponding components, such as tension bars, roller blind tracks, gliders, and / or others. In addition, the component 100 also has two longitudinal sides 107 and a rear side 108.
[0056] The drive cable holder 101 is designed as a frame and has two opposing longitudinal frame sections 109 and at least one transverse frame section 110 in the region of the rear side 108. The longitudinal frame sections 109 are each assigned to a guide rail for actuating the shading system 104 and are designed, for example, symmetrically to one another. Furthermore, the drive cable holder 101 has a transverse part 111, which is arranged approximately parallel and offset inwardly relative to the transverse frame section 110 in the region of the rear side 108. All of the described sections of the drive cable holder 101 are formed in one piece and foamed onto the component 100.
[0057] The drive cable assembly 100 has one or more guide tubes 112, as described below. The guide tubes 112 are each designed to guide a drive cable, via which the shading system 104 can be actuated. The drive cables are driven by a drive 113.
[0058] The holding body 103 is formed, in particular, from a foamed plastic 114. The holding body 103 is manufactured using a foaming process in which comparatively low pressures of up to a maximum of 6 bar prevail in a mold. During foaming in the mold, the plastic 106 expands and surrounds the components in the mold accordingly. This makes it possible to dispense with injection-molded plastic parts. The holding body 103 is, in particular, not manufactured using an injection-molded process in which comparatively high internal pressures prevail in the mold. The comparatively high internal pressures would, for example, cause the comparatively thin-walled guide tubes 112 to yield and deform.
[0059] Further details are given below based on the Fig. 2 to 7, all of which show schematic sectional views at different locations of the component 100.
[0060] Fig. 2 shows section XX in the transverse frame element 110, in which two guide tubes 112 are held side by side in the holding body 103. The guide tubes 112 are, for example, each made of plastic tubes and are integrally connected to the holding body 103. The holding body 103 completely surrounds the guide tubes 112 in sections to hold the guide tubes 112. In particular, transversely to the vehicle's longitudinal direction 105, the guide tubes 112 are each completely radially surrounded in sections by the holding body 103.
[0061] By attaching the guide tubes 112 directly in the foamed plastic 114 of the holding body 103, the guide tubes 112 are held without having to be subsequently inserted into the holding body 103. This eliminates the need for structural aids for subsequently inserting the guide tubes. This allows for a smaller installation space requirement, making production and assembly overall less complex and thus more efficient. The installation space required for the component 100 and the drive cable holder 101 is reduced. This increases the visibility of the component 100 as a fixed glass element. The area occupied by the component 100 within the roof opening is reduced.
[0062] The guide tubes 112 can be arranged side by side, overlapping, or offset from one another. After the plastic 114 has cured, the holding body 103 sufficiently supports the guide tubes 112, allowing reliable guidance of the drive cables during operation. Tensile and / or compressive forces are reliably supported.
[0063] In the described foaming process, the plastic 114 expands in the molding tool such that it sufficiently surrounds the guide tubes 112 to hold them in place. It is also possible to arrange three, four, or more tubes one above the other with a small gap, since the plastic can also surround such geometries through foaming. The guide tubes 112 only need to be held in the molding tool at a few points during the foaming process. In the remaining areas, the plastic 114 completely radially surrounds the guide tubes 112 after curing. The drive cable holder 100 according to section XX is designed accordingly on the other side of the drive 113.
[0064] Fig. Figure 3 shows, by way of example, how a guide tube 112 is held in the mold during the production of the holding body 103. A holding element 115 is provided for this purpose. This element is fixedly arranged in the mold and holds the guide tube 112 on one side, i.e., from a side facing away from the component 100. For this purpose, the holding element 115 has an undercut 116 to hold the guide tube 112 in a locking manner. For example, the holding element 115 is designed as a clip.
[0065] In the mold, the guide tubes 112 are each held at specific points by several holding elements 115. The holding elements 115 can be an integral part of the mold or separate elements. The holding elements 115 are removed, for example, after the plastic 114 has cured. In the finished holding body 103, free access points 117 to the guide tubes 112 are formed at the locations corresponding to the positions of the holding elements 115. However, these are only formed in a small portion of the guide tubes 112, so that the holding body 103 provides sufficient support for the guide tubes 112.
[0066] Alternatively or additionally, the holding elements 115 remain in the finished holding body 103 and thus the drive cable holder 100.
[0067] Fig. 4 shows the section AA through a longitudinal frame section 109, in which the two guide tubes 112 lie one above the other. In addition, a guide rail 118 is mounted on the longitudinal frame section 109 of the drive cable holder 100. The guide rail 118 has a guide rail channel 119 in which a slider 120 of the shading system 104 is slidably mounted. The lower guide tube 112 has a longitudinal slot 121 along the longitudinal frame section 109. The longitudinal slot 121 is open toward the guide rail channel 119 so that a drive cable can be coupled to the slider 120 directly and over a short distance. The longitudinal slot 121 extends at least over a length that corresponds to the movement of the slider 120.
[0068] The longitudinal slot 121 is already provided during the manufacture of the drive cable holder 100, i.e., the guide tube 112 with the longitudinal slot 121 is positioned in the mold, wherein the longitudinal slot 121 is sealed or covered during the introduction of the plastic 114, so that the plastic 114 cannot flow into the guide tube 112. This enables the advantages and functions mentioned above.
[0069] Fig. 5 shows section BB through the longitudinal frame section 109, which is essentially similar to section AA, with the addition that the fastening of the guide rail 118 is shown. For this purpose, a fastening receptacle 122 is integrated into the holding body 103. The fastening receptacle 122 has, for example, a threaded insert, by means of which the guide rail 118 is screwed to the holding body 103 in the longitudinal frame section 109. The fastening receptacle 122 is produced during the foaming process. The threaded insert can be inserted before foaming or subsequently. Many other fastening configurations are conceivable. Fig. 6 and Fig. 7 show sections CC and DD through the cross member 111 at two different positions. The cross member 111 has no guide tubes. At certain positions according to section CC, the cross member 111 has a first profile 123, which forms a receptacle 124 for one or more components of a shading system 104. The receptacle 124 is designed in particular such that an interior headliner can be positively connected to the cross member 111, in particular without further fastening elements. Furthermore, the first profile 123 of the cross member 111 in section CC is designed such that a support 125 for a bow 126 is formed. At other locations, the cross member 111 is designed according to section DD such that only the support 125 is formed.
[0070] As shown by the Fig. 4 and Fig.As can be seen in Figure 5, the guide rail 118 has a second profile 127, which also forms a receptacle 128, so that the headliner can also be positively attached to the guide rail 118. The first and second profiles 123 and 127 can merge into one another, for example seamlessly.
[0071] The fastening of the inner headliner to the cross member 111 and the guide rail 118 allows for a particularly simple and space-saving, compact design.
[0072] The drive 113 is, for example, attached to a holder (not explicitly shown), which is an integral part of the drive cable holder 100. The holder is, for example, part of the holding body 103 and has a corresponding shape. Alternatively, the holder is positioned in the mold during production, analogous to the guide tubes 112, and is connected to the holding body 103 by introducing the plastic 114, for example by a material fit. Thus, it is possible, for example, to mold the drive cable holder 100 with a holder and the guide tubes 112 directly onto the component 100. Multiple holders and drives can also be provided.
[0073] The drive 113 is, in particular, an electric drive and comprises, for example, an electric motor. In the operational state, the electric motor engages a drive cable, so that the drive 113 can move the drive cable relative to the corresponding guide tube 112 along the vehicle's longitudinal direction 105.
[0074] The following briefly describes the production of the component with the drive cable holder. The component 100 is introduced into the mold together with a guide tube 112 and, if applicable, other components, such as the aforementioned holder and other guide tubes. The guide tube 112 is held in a predetermined position relative to the component 100 by holding elements 115. The inner walls of the mold have the shape that the holding body 103 is later to have. Subsequently, the plastic to be foamed, which may consist of several components, is introduced into the mold. In particular, the plastic 114 is introduced into the mold under a low pressure of less than 10 bar, in particular under a pressure between 1 bar and 6 bar. There, the components react and foam together to form polyurethane.The plastic 114 spreads out in such a way that it surrounds the guide tube 112 and forms the material-locking connection with the component 100, in particular on the surface 102.
[0075] By directly foaming the drive cable holder 101 onto the component 100, cost-effective production and a high degree of integration are possible.
