Description

[0001] Vehicle roof cover with a cable connection

[0002] The invention relates to a cover of a vehicle roof which is provided for movable mounting on a vehicle roof and which has a trailing cable on its underside for electrical connection to a connecting cable.

[0003] DE 196 50 227 C1 discloses a cover that is movably mounted on a vehicle roof and is electrically connected to a roof frame by means of a trailing cable. The electrical connection provided by the trailing cable is formed by a ribbon cable. The ribbon cable is designed to be flexurally elastic in such a way that it is bent into a U-shape between its attachment points on the cover and on the roof frame, and it has such flexural rigidity that sagging between the attachment points can be avoided. The flexural rigidity can be increased by incorporating a steel strip into the center of the ribbon cable. The steel strip is encased in a carrier material of the ribbon cable, such as PVC, and is arranged between power lines that run along the lateral edge region of the ribbon cable.A cover-mounted contact surface of the ribbon cable can contain ferromagnetic material that attracts the steel strip due to its magnetic properties and counteracts sagging of the ribbon cable.

[0004] The invention is based on the object of creating a cover mentioned above, the electrical connection of which is improved by means of the trailing cable, and of providing a vehicle roof with such a cover. This object is achieved according to the invention in the cover mentioned above in that the trailing cable has a cable arrangement with at least two flat ribbon cables arranged one above the other.

[0005] Advantageous embodiments of the invention are specified in the dependent claims.

[0006] Since the cable assembly comprises at least two ribbon cables arranged one above the other, the number of electrical conductors of the trailing cable can be increased compared to a single ribbon cable. The thickness or height of the cable assembly of the trailing cable is thereby increased, whereas an increase in the width of the cable assembly of the trailing cable is not necessary for an increased number of conductors. The at least two, three, or more ribbon cables form a unit in the cable assembly, which remains intact during the movement of the trailing cable.

[0007] Because there is no need to increase the width of the cable arrangement, which is expediently arranged in or near the lateral edge region of the lid, a large see-through area is retained in the interior of the lid next to the trailing cable in a glass lid. The lid can have a trailing cable on one lateral region or a trailing cable on each of the two opposite lateral regions. Since a lid is designed symmetrically, particularly with regard to its two opposite lateral regions on which a lid bearing or lid bearing mechanism is arranged, if only a narrow trailing cable is arranged on one lateral region, the opposite lateral region can also be designed to have a similar appearance, e.g. by means of a narrow cover, cladding or foam encasing the lid. The see-through area is therefore comparatively large.

[0008] Each ribbon cable has several electrically conductive wires, conductors or tracks that are essentially arranged next to each other in one plane, for example, embedded in a plastic material such as PVC or laminated between two plastic films.

[0009] The cable arrangement comprises a number of individual ribbon cables that together can provide the required total number of conductors. The individual ribbon cables can be of the same type or identical, or even different, particularly with regard to the number of conductors. This means that such a cable arrangement can be flexibly configured depending on the required total number of conductors. If a trailing cable with, for example, six conductors is required, a cable arrangement with two ribbon cables, each with three conductors, is provided. If only five conductors are required, two such ribbon cables, each with three conductors, can be used, although only five conductors are used in total.

[0010] The cable arrangement thus dispenses with the use of such known ribbon cables which, for the transmission of a larger number of signals, have two or more conductor track layers arranged one above the other in a fixed, integral arrangement in only one ribbon cable.

[0011] The cover is essentially a movable roof element of a vehicle roof. The cover is, in particular, part of an openable roof system, such as a spoiler roof or a sliding roof, and, in its closed position, is arranged in a roof opening of the vehicle roof. The cover is, for example, a transparent cover or a glass cover. The cover is movably mounted on the vehicle roof by means of a bearing device and can be displaced in a longitudinal opening movement over an adjacent roof surface part or under such a roof surface part. The trailing cable can also provide a connection between this movable first cover and a further second cover, which is arranged fixedly or movably on the vehicle roof and relative to which the first cover is movable.

[0012] The ribbon cables are expediently arranged congruently one above the other if they have the same width or approximately the same width. However, the ribbon cables can also be slightly offset from one another in the transverse or width direction. A wider ribbon cable can be arranged relative to a narrower ribbon cable such that it protrudes beyond the narrower ribbon cable at one side edge or at both side edges. The ribbon cables are in particular arranged directly one above the other. Due to the plastic material enclosing the wires or conductors, sufficient insulation of the ribbon cables lying on top of one another is ensured. However, in the case of ribbon cables lying on top of one another, a separating layer can also be arranged between the two adjacent ribbon cables.However, such a separating layer should not excessively increase the dimensional rigidity of the cable arrangement of a trailing cable, because the flexibility of the trailing cable during its towing movement during the opening and closing of the cover must be ensured.

[0013] Furthermore, it can be provided that the ribbon cables are positioned in a fixed relationship to one another at least at certain points or are firmly connected to one another by means of at least one positioning means or connecting means. Such connecting or positioning means include, for example, clamps, clips, clamps, or even adhesives. However, care must be taken here too to ensure that the dimensional rigidity of the cable arrangement of a trailing cable is not excessively increased.

[0014] The ribbon cables of the cable arrangement are preferably enclosed by a sheath or sleeve. The sheath provides, for example, protection, insulation, and visual design options for the cable arrangement or trailing cable. The sheath is formed, for example, by a fabric sleeve, a fabric-textile sleeve, or a braided sleeve. A braided sleeve, for example, is designed such that it can be unfolded along its length and automatically closes again after the ribbon cables have been inserted. The ribbon cables can also be pushed into the sheath. In principle, the sheath is designed or made of such a material that the elasticity and flexibility of the trailing cable are not impaired when the cover is adjusted.According to a particularly preferred embodiment, the sheath or casing keeps the ribbon cables positioned relative to one another in their stacked or superimposed arrangement. In particular, the sheath tensions the ribbon cables against one another. An additional connecting or positioning means that firmly connects the individual ribbon cables to one another or firmly positions them relative to one another is not required. Thus, when using such a sheath, the cable arrangement of the trailing cable is formed without the need for additional connecting or positioning means.

[0015] The cable arrangement preferably additionally contains a particularly magnetic spring steel band. Such a preferably stainless spring steel band has a thickness of, for example, approximately 0.2 mm. The spring steel band increases the flexural rigidity of the cable arrangement and counteracts sagging of the free section of the trailing cable, but still allows the trailing cable to be bent at the U-shaped loop over an angle of, for example, approximately 180°. The spring steel band expediently has approximately the width of the ribbon cables. Preferably, the spring steel band is accommodated in the sheath in a layer-like manner, adjacent to one of the ribbon cables. The spring steel band is thus held by the sheath on the cable arrangement. Fastening or connecting the spring steel band to or with the ribbon cables is not required. The arrangement of the spring steel band relative to the ribbon cables, i.e.on the ribbon cables or under the ribbon cables in relation to the installation position of the trailing cable, is selectable.

[0016] The contacts of the conductors of each ribbon cable are expediently connected by means of contact connections to associated contacts of, for example, the roof-side connecting cable and / or a cover-side connecting cable, for example. The contact connections are preferably formed as ultrasonic welded connections, but can also be formed, for example, as soldered connections. For example, a round conductor cable represents such a connecting cable. However, other cables or conductive elements can also form such connecting cables. In principle, plug connections or connectors can also provide such contact connections. According to a preferred embodiment, provision is made for a separating or insulating layer to be arranged between the contact connections of two superimposed ribbon cables. Such a separating or insulating layer is, for example, an insulating separating film.The separating or insulating layer provides secure electrical separation of the contacts of the individual ribbon cables in the area of ​​the cable connections.

[0017] It is advisable to provide an overmold that encloses the cable assembly and the connecting cable in the area of ​​the contact connections. Such an overmold with a plastic material provides protection and sealing for the area of ​​the contact connections and, expediently, also for an adjacent area of ​​the trailing cable and the connecting cable.

[0018] According to a further preferred embodiment, the lid has at least one magnet attracting the magnetic spring steel band, positioned on the lid underside in such a way that it pulls the trailing cable, which has the spring steel band, toward the lid underside. This prevents the free upper section of the trailing cable from sagging and possibly flapping when the lid is in the open position.

[0019] The cover is expediently provided with an edge-side cover frame. The cover frame is preferably formed by means of a PU edge foam. The at least one magnet is attached to the cover frame. Expediently, the overmolding of the contact connections of the trailing cable is attached to the cover frame. The overmolding can thus form a holder for the trailing cable on the cover. The overmolding of the contact connections at the opposite end of the trailing cable is expediently attached to a support part, which, as a roof-side support part, is formed, for example, by a roof frame or a guide rail of a cover bearing mechanism, or, as a cover-side support part, is part of another cover of the vehicle roof.

[0020] The overmolding expediently contains a fastening element, particularly manufactured using a two-component injection molding process. The fastening element is intended for fastening the overmolding to an associated part of the cover, to an associated part arranged on the roof side, or to an associated part of another cover. The fastening element is expediently a part manufactured with the overmolding or a stand-alone part that is connected to the overmolding, e.g., by form-fitting fastening and / or bonding.

[0021] The fastening element can be made of a soft material, e.g., TPU with a hardness of 85. Preferably, the fastening element is made of a hard plastic, e.g., a plastic such as polyamide (PA) or polypropylene (PP) or polyurethane (PU), which may also contain reinforcing materials such as glass fibers or the like.

[0022] According to a preferred embodiment, the fastening element has a locking head that is inserted into a fastening recess on the cover or on a roof-side support part, in particular on a guide rail, preferably a cover bearing mechanism. The fastening element has, for example, an elongated base web with the likewise elongated locking head for engagement in a correspondingly elongated fastening recess. Such an elongated fastening recess is aligned in the longitudinal direction of the trailing cable. However, the fastening element can also be a part with a round, oval, or square cross-section, for example, and which has a conical locking head, for example. Such a fastening element can be inserted into both an elongated fastening recess and a fastening recess that is, for example, round or square.The fastening element can be formed with a slot or a longitudinal slot that extends at least through the locking head and can also extend into the base web or generally into a base of the fastening element. The slot or longitudinal slot provides the fastening element with advantageous flexibility for inserting the locking head into the fastening recess.

[0023] According to a further preferred embodiment, the overmolding has a fastening flange that encloses the ribbon cable or the cable arrangement. The fastening flange expediently contains a thickened portion at its end region facing away from the overmolding. The thickened portion is preferably oriented transversely to the longitudinal extent of the ribbon cable and is formed, for example, by two opposing beads. It is particularly preferred that an end section of the sheath of the ribbon cable is arranged on the fastening flange and / or that a heat-shrink tube encompassing the ribbon cable or the cable arrangement or the sheath is shrunk onto the fastening flange. The fastening flange enables secure attachment of the sheath to the overmolding. The thickened portion or the beads support security against accidental removal of the sheath, which fits tightly against the thickened portion or the beads.A heat-shrink tube that surrounds the cable assembly or the sheath and is shrunk onto the mounting flange presses the sheath against the mounting flange, particularly against the thickened portion or bulges. This ensures a secure hold and a permanent seal for the ribbon cable or the cable assembly.

[0024] The object is further achieved by a vehicle roof according to claim 15, which has a cover according to one of claims 1 to 14, wherein the cover can further be formed according to the above embodiments. The cover is movably mounted on the vehicle roof. The cover is, in particular, a glass cover of a sliding roof unit or a roof element such as a panoramic roof.

[0040] A vehicle roof 1 of a vehicle 2, such as a passenger car, has a roof opening 3 (Fig. 1) which can be selectively closed or at least partially exposed by a cover 4. The cover 4 is movably mounted on the vehicle roof 1, e.g. on a roof frame or a guide rail 37 (Fig. 14) of the vehicle roof 1, in such a way that it can be displaced from its closed position in the longitudinal direction of the vehicle rearward over a rear roof surface 5 or under the rear roof surface 5. The cover 4 is in particular a part of an openable roof system, such as a spoiler roof or a sliding roof. The cover 4 is in particular a glass cover. The cover 4 has at least one electrical device (not shown) which is connected to a vehicle-side electrical system by means of a trailing cable 6 (Figs. 2 and 3) and a roof-side connecting line 7 connected thereto.Such an electrical device comprises electrical or electronic components such as solar cells, lighting, sensors, etc. The trailing cable 6 carries the power supply and the flow of information between the electrical device or components and the vehicle's electrical system.

[0041] The trailing cable 6 rests on a part of the vehicle roof 1, such as the roof frame, part of a guide rail 37 of a bearing mechanism of the cover 4, or basically a roof-side support part, and is connected at its roof-side or rear end 8 to the roof-side connecting cable 7. The trailing cable 6 is bent into a U-shape at an angle of approximately 180° towards the cover 4 towards its cover-side or front end 9, forming a loop 10 that opens towards the cover rear edge 11, and is fastened at its front end 9 to the cover underside 12. The trailing cable 6 is connected at its front end 9 to a cover-side connecting cable 13. The trailing cable 6 extends below a lateral edge region 14 of the cover 4 in the longitudinal direction of the cover.

[0042] When the cover 4 is closed (Fig. 3 and 5), the loop 10 is located close to the front end 9 of the towing cable 6 fixed to the cover 4. When the cover 4 is adjusted from its closed position (Fig. 3 and 5) into an open position according to Fig. 4 and 6 in the longitudinal direction of the cover, the towing cable 6 rolls off on the underside 12 of the cover while maintaining the bend in the form of the loop 10, while it lifts off from the roof frame (not shown).

[0043] The trailing cable 6 has a cable arrangement 15 containing at least two ribbon cables 16 and 17 (Figs. 5 and 6) arranged one above the other. In the illustrated embodiment, the cable arrangement 15 contains two ribbon cables 16 and 17, which are preferably formed identically, each contain three conductors 18, and are arranged congruently one above the other and one above the other. The two ribbon cables 16, 17 are surrounded by a sheath 19. The sheath 19 or sleeve is, for example, a fabric hose or a braided hose. The sheath 19 can also be a shrink tube.

[0044] A spring steel strip 20 is accommodated in the sheath 19. The spring steel strip 20 preferably lies on the ribbon cable 16 arranged adjacent to the lid underside 12 when the trailing cable 6 unwinds and rests against the lid underside 12.

[0045] At least one magnet 21 is attached to the lid 4 on its underside 12. The magnet 21 is intended to attract the magnetic spring steel strip 20 when the trailing cable 6 approaches the magnet 21 from below as it unwinds. Accordingly, the magnet 21 is attached to the lid 4 on the unwinding path of the trailing cable 6 at a distance from the front end 9 of the trailing cable 6. The magnet 21 is preferably attached to a lateral lid frame 22. The lid frame 22 is formed, for example, by a polyurethane foam 23 on the lateral lid edge 24 and extends in a strip-like manner on the underside 12 of the lid in the edge region 14 of the lid 14 along the lateral lid edge 24. The lid frame 22 expediently contains a panel 25 on the lateral lid edge 24, against which a lid seal 26 (Fig. 1) rests or is attached.

[0046] The magnet 21 is attached to the cover frame 22, for example, by adhesive bonding or foaming. The magnet 21 can, in principle, be glued to the cover underside 12, even outside of a cover frame 22. The magnet 21 can be formed as a point or as an elongated part, so that it extends over a longer area along the unwinding path of the trailing cable 6.

[0047] When the tow cable 6 unwinds on the underside 12 of the lid when the lid 4 is opened, it is held by the magnet 21 on the underside 12 of the lid, preventing it from sagging downwards toward the vehicle interior. The magnetic spring steel band 20 is attracted by the magnet 21, pressing the sheath 19 against the magnet 21. Thus, the spring steel band 20 holds the cable assembly 15 to the underside 12 of the lid via the sheath 19. The spring steel band 20 also holds the cable assembly 15, and thus the tow cable 6, to the underside 12 of the lid, particularly in the area of ​​the bend or loop 10, due to its inherent resistance to deformation.

[0048] At the front end 9 of the trailing cable 6, the conductors 18 of the ribbon cables 16, 17 form end contacts 27 (Fig. 7), which are connected to associated contacts 28 of the roof-side connecting cable 13 by means of contact connections 29. The contact connections 29 are preferably made by means of ultrasonic welding or, for example, by means of soldering connections.

[0049] A separating or insulating layer 30 is arranged between the contact connections 29 of two superimposed ribbon cables 16 and 17. Such a separating or insulating layer 30 is, for example, an insulating separating film. The separating or insulating layer 30 provides reliable electrical separation of the contacts 27 of the individual ribbon cables 16 and 17 and the contacts 28 of the connecting cable 13 in the area of ​​the cable connections 29. The separating or insulating layer 30 is expediently inserted after the contact connections 29 have been established or after the contacts 27 and 28 have been welded.

[0050] An overmolding 31 is provided (Fig. 9) that encloses the cable arrangement 15 and the connecting cable 13 in the area of ​​the contact connections 29. Such an overmolding 31 is made in particular from a plastic or rubber-like material and forms a protection and seal for this area of ​​the contact connections 29 and expediently also for an adjoining area of ​​the trailing cable 6 and the connecting cable 13. The overmolding 31 is formed, for example, as a cuboid-shaped part. The overmolding 31 is attached to the cover frame 22, for example, by gluing. The overmolding 31 can also have a projection 32 on the top, which is inserted into a recess 33 in the cover frame 22. This projection 32 can serve to position the overmolding 31 on the cover frame 22 and can also be formed as part of a plug-in, clamp-in or snap-in connection with which the overmolding 31 is fixed to the cover frame 22.

[0051] The contact connection 29 described above is expediently formed in the same way and with the same overmolding 31 at the rear end 8 of the trailing cable 6 for connection to the roof-side connecting cable 7.

[0052] In the cover 4 according to the invention, the design of the trailing cable 6 with the compact cable arrangement 15 comprising several ribbon cables 16, 17 thus enables an increase in the number of conductors 18 while maintaining the small width of the trailing cable 6. The visible width of a cover 4, e.g., of a sunroof or a roof element, is therefore not reduced even with an increasing number of required conductors 18. The reinforcement of the trailing cable 6 by means of the spring steel strip 20 and / or the magnetic force of the magnet 21 attracting the trailing cable 6 prevent the trailing cable 6 from sagging and flapping along its free cable length.

[0053] According to one embodiment (see Figs. 10 to 16), the overmolding 31 of the contact connection 29 of the trailing cable 6 shown in each case has a projection 32 in the form of a fastening element 34, which is arranged on a fastening surface 35 of the overmolding 31 and has a locking head 36. The overmolding 31 on the cover-side or front end 9 of the trailing cable 6 rests with its fastening surface 35 on the PU foam 23 of the cover frame 22 (Fig. 14). The other overmolding 31 on the roof-side or rear end 8 of the trailing cable 6 rests with its fastening surface 35 on a roof frame and in particular on a roof-side guide rail 37 (Fig. 15).

[0054] The fastening element 34 has a base web 38 which extends centrally and longitudinally along the fastening surface 35 approximately over the length of the fastening surface 35 and protrudes from it. The locking head 36 of the fastening element 34 contains two opposing conical surfaces 39 with lower locking projections 40 which protrude beyond the base web 38. The locking projections 40 are spaced from the fastening surface 35. The PU foam 23 of the cover frame 22 has a fastening recess 41 adapted to the fastening element 34, which is formed as an elongated groove with an undercut groove base 42 for lockingly receiving the locking head 36 of the fastening element 34 inserted into the fastening recess 41.The fastening recess 41 is formed at least slightly longer than the fastening element 34, so that when the overmolding 31 is mounted, the fastening element 34 is received therein with play in the longitudinal direction, but nevertheless assumes its intended mounting position on the cover 4 and essentially maintains it, taking the play into account.

[0055] The fastening element 34 is expediently made of a material that is harder than the material of the PU foam 23, so that it has sufficiently high stability when inserted into the fastening recess 41. However, the fastening element 34 is so flexible that the PU material of the PU foam 23 is elastically deformed by the locking head 36 upon insertion. Disassembly of the overmolding 13 is possible by pulling the fastening element 34 out of its locking position in the fastening recess 41.

[0056] The overmolding 31 is preferably manufactured with the fastening element 34 using a two-component injection molding process. The fastening element 34 can be manufactured with the overmolding 31 in one mold or in two molds of an injection molding tool in one step or in multiple steps.

[0057] The fastening element 34 can generally be made of a soft material, e.g., TPU with a hardness of 85.

[0058] Preferably, the fastening element 34 is made of hard plastic, e.g.

[0059] B. from a plastic such as polyamide (PA) or polypropylene (PP) or polyurethane (PU), which may also contain reinforcing materials such as glass fibers or the like. The fastening element 34, made of hard plastic, is subject to less deformation when inserted into the fastening recess 41 and supports secure assembly and fixation. The overmolding 31 is made, for example, from an elastomer or a thermoplastic, preferably based on a polyurethane.

[0060] The fastening element 34 of the overmolding 31 at the roof-side or rear end 8 of the trailing cable 6 is assigned a fastening recess 43 formed in the guide rail 37 (Fig. 15). This fastening element 34 of the other overmolding 31 is fundamentally similar to the first-mentioned fastening element 34 of the cover-side overmolding 31. The guide rail 37 is formed, in particular, from a light metal such as aluminum and is therefore made of a harder material compared to the PU material of the PU foam 23. The fastening recess 43 is formed, for example, as an opening in the form of an elongated hole, the length of which is adapted to accommodate the fastening element 34 to be inserted. The fastening element 34 has a longitudinal slot 44 that extends through the locking head 36 and into the base web 38.When the overmolding 31 is attached to an upper side 45 of the guide rail 37, the fastening element 34 is inserted into the fastening recess 43. The longitudinal slot 44 enables the two halves of the locking head 36 to be pressed against one another under elastic deformation, so that the locking head 36 can be inserted through the fastening recess 43, which has a smaller width than the locking head 36. When the overmolding 31, in its assembled position, rests with its fastening surface 35 on the upper side 45 of the guide rail 37, the two halves of the locking head 36 inserted through the fastening recess 43 spread apart again into their original positions and the two locking projections 40 engage behind the underside or rear side 46 of the guide rail 37 in locking engagement.Even if the fastening element 34 of this overmolding 31 is made of a hard material, the locking head 36 of the fastening element 34 has the necessary deformability for assembly due to the longitudinal slot 44, since the hardness of the material of the guide rail 37 prevents it from deforming when the locking head 36 is inserted. If the fastening element 34 of this overmolding 31 is made of a soft material, such a longitudinal slot 44 can be omitted. The guide rail 37, or at least that part of the guide rail 37 to which the trailing cable 6 rests and the overmolding 31 is fastened, is made, for example, of metal or a light metal such as aluminum, or even of a plastic, and can be either rigid or elastic.

[0061] The fastening element 34 is expediently additionally held at the lower end of its base web 38 by means of a positive connection 47 (Fig. 12). The positive connection 47 contains an overlapping section 48 of the overmolding 31, which overlaps an extended base 49 or a plate-like base of the base web 38, in particular circumferentially on the base web 38. This secures the base web 38 formed on the overmolding 31 against being pulled off the overmolding 31.

[0062] The overmolding 31 has a fastening flange 50 (Fig. 12) that encloses the two ribbon cables 16 and 17 and expediently has a thickening in the form of two opposing beads 51 at the end facing away from the overmolding 31 in the longitudinal direction. A fabric hose surrounding the ribbon cables 16, 17 as a sheath 19 extends with one end section over the beads 51 to the fastening flange 50 and ends with its end section preferably spaced from the overmolding 31. A shrink tube 52 is pulled onto the ends of the ribbon cables 16, 17 surrounded by the sheath 19 and presses the sheath 19 or the fabric hose against the beads 51 and against the fastening flange 50.The shrink tube 52 thus fixes the fabric tube to the mounting flange 50 and seals the two ribbon cables 16, 17 (flexible flat cable or FFC), particularly in a sealing area 53 in which it both directly rests against the mounting flange 50 and presses the end area of ​​the fabric tube against the mounting flange 50. In this way, the ribbon cables 16, 17 are permanently protected at the transition to the overmolding 31. This protection is particularly advantageous at the overmolding 31 on the cover-side or front end 9 of the trailing cable 6, since here the ribbon cables 16, 17 are subject to greater stress due to the bending movement of the trailing cable 6 in the area of ​​the loop 10.

[0063] Preferably, the overmolding 31 includes a flange 54 opposite the mounting flange 50. The insulating sheaths 55 of the individual conductors of the connecting cable 7 or 13 are molded into this flange 54. A shrink tube can also be provided on this flange 54, sealing the connecting cable 7 or 13 from the overmolding 31.

[0064] The sheath 19 is expediently formed by a fabric hose, made, for example, of polyester, or a fabric-textile hose. Such a fabric-textile hose represents a combination of a fabric hose with a textile hose, which is advantageously softer and causes less creaking noise when the trailing cable 6 rubs against other components, such as the PU foam 23 of the cover 4 and the guide rail 37. Such a fabric-textile hose contains, for example, PET multifilaments and a dense textile fabric (PET-HD).

[0065] During the production of the trailing cable 6, the sheath 19 or the fabric hose and the shrink hose 52 are first pulled over the free end of the superimposed ribbon cables 16 and 17. Subsequently, the contacts 27 of the conductors 18 of the respective ribbon cables 16 and 17 are connected to the corresponding contacts 28 of the round conductors of the connecting cable 7 or 13, which are surrounded by the insulating sleeves 55, as contact connections 29, e.g.

[0066] B. by welding, in particular ultrasonic welding, if necessary with the interposition of at least one separating or insulating layer 30. During the subsequent injection molding of the overmolding 31, the ends of the ribbon cables 16, 17 and the ends of the round conductors as well as their contact connections 29 are overmolded so that they are sealed in the overmolding 31. The fastening element 34 is produced, for example, during the production of the overmolding 31 in a 2K injection molding process. After the production of the overmolding 31 with the fastening element 34, the fabric hose 19 and the shrink hose 52 are arranged on the fastening flange 50. The shrink hose 52 is shrunk by thermal treatment so that it fixes and seals the fabric hose and thus also the ribbon cables 16 and 17 on the flange 50.

[0067] In an alternative embodiment, the fastening element 34 is manufactured as a separate component and arranged and fixed to the overmolding 31, e.g., by gluing it to the fastening surface 35 of the overmolding 31 or by inserting the base web 38 into a recess in the fastening surface 35, in which the fastening element 34 is clamped and / or glued.

[0068] Fig. 13, which shows the cover 4 without the guide rail 37, shows an embodiment with several magnets 21 arranged at a distance from one another on the PU foam 23 along the unwinding path of the trailing cable 6. The magnets 21, e.g., neodymium magnets, are glued or foamed onto the PU foam 23.
