Description

Method for producing a drive cable holder for a vehicle roof and component for a vehicle roof

Technical Field

The invention relates to a method for producing a drive cable holder for a vehicle roof. Furthermore, a component for a vehicle roof is proposed, which has a drive cable holder.

Background

The motor vehicle can have a roof opening which can be closed by means of a movable cover and can be at least partially open. For example, the movement of the cover is driven by means of a drive, which is coupled to the cover by means of a drive cable. It is also possible to provide a roller blind in the motor vehicle, which roller blind can be moved by means of a drive and a drive cable. The drive cable is guided, for example, in a catheter, as described in DE 10144 742a 1.

Disclosure of Invention

It is desirable to propose a method for producing a drive cable holder for a vehicle roof, which method has a simple production with good integration. It is furthermore desirable to provide a component for a vehicle roof with a drive cable holder, wherein the component is cost-effective and relatively simple to produce.

According to one aspect, a method for manufacturing a drive cable holder for a roof of a vehicle is disclosed. The method comprises the following steps:

-providing a member for a vehicle roof;

-positioning the component in a forming tool;

-providing a conduit for operating a drive cable of a shade system of a vehicle, wherein the conduit has a longitudinal slit or perforations for the longitudinal slit;

-positioning the catheter in a forming tool;

introducing plastic into the forming tool, thereby

-the plastic at least partially surrounds the catheter, wherein the plastic is prevented from entering the catheter through the longitudinal slit or surrounding the catheter in the area of the perforation; and is also provided with

-the plastic is bonded to the surface of the component in a material-locking manner, and thereby

-forming a drive cable holder fastened to the component, in particular in the case of hardening of the plastic.

The method enables direct attachment of the catheter to the member. Additional fastening elements, such as rivets or bolts or adhesive connections, can be dispensed with. Subsequent pushing of the catheter into the shaped channel can be eliminated. Furthermore, a small number of method steps is sufficient. Compared to conventional manufacturing methods, in which the guide tube is fastened later in a plastic part manufactured by injection molding, method steps and thus costs are saved. Furthermore, no auxiliary mechanism is required, which is generally necessary for introducing the tube into the plastic part. Furthermore, the drive cable holder is more space-saving than conventional plastic parts. Furthermore, the drive cable holder has a comparatively small installation space requirement and has particularly good sound insulation with respect to the operating noise of the drive cable moving in the conduit. A small installation space size for the drive element can also be achieved. This increases the perspective, for example, in the case of a transparent roof.

In particular, it should be emphasized that the conduit has been slotted before the drive cable holder is formed. The longitudinal slit here extends over a section of the catheter and does not have to extend over the entire length of the tube. In the manufacture of the drive cable holder, the longitudinal slit is suitably covered, sealed or closed before the plastic is introduced into the interior of the catheter. For example, the guide tube is correspondingly positioned and the shaping of the shaping tool is correspondingly configured such that the wall of the shaping tool covers the longitudinal slit. Alternatively or additionally, the shaping tool has a projection which, during manufacture, passes through the longitudinal slit into the catheter and thereby protects the longitudinal slit from the entry of plastic. Alternatively or additionally, a sealing element or the like is provided to prevent the entry of plastic into the catheter.

Instead, perforations for the longitudinal slots are provided, so that the longitudinal slots can be introduced later particularly simply. No special measures have to be taken for this in the production process for sealing the catheter. By "perforation" is understood a material weakening which allows easy opening of the tube and/or introduction of slits.

For example, to a point or continuous material weakness along the longitudinal direction/pull-out direction. For example, one or more notches (Kerben) are provided along the pull-out direction.

After the production of the drive cable holder, the longitudinal slot can thus be freely accessed directly or can be introduced later in a simple manner. Such as the elimination of expensive subsequent slotting or removal of the auxiliary component. The manufacturing process of the drive cable holder with the slotted guide tube is thereby particularly efficient and resource-saving.

The longitudinal slot is for example provided for coupling the drive cable in the guide tube with a movable element, for example a slide or a slider guided displaceably in the guide rail. Thus, the movable element may be directly coupled and moved. For example, shade systems, such as sunshade roller shades, can be operated thereby for shading glass covers or fixed glass parts.

A material-locking connection is formed between the plastic and the component for fastening the drive cable holder to the component. In particular, the plastic is introduced into the molding tool in such a way that a cohesive connection is formed. It is thereby possible to dispense with further mechanical connections for holding the drive cable holder on the component.

The drive cable holder can at the same time be used as an attachment of a frame, edge and/or component on the vehicle or roof. For this purpose, the drive cable holder has, for example, a receptacle and/or fastening elements integrated in the production. This enables saving of further components by integration of attachment and production manufacturing of the drive element required in existing manufacturing processes.

The catheter is surrounded as completely as possible by plastic, for example, except at least in the region in which the longitudinal slits or perforations are located. Since the longitudinal slits or perforations extend, for example, only over a small circumferential region of the catheter, i.e. have a small width or opening in the circumferential direction, the catheter is nevertheless sufficiently surrounded by plastic in the region of the longitudinal slits or perforations. For example plastic, surrounds the catheter by at least 180 °, for example 270 °, so as to reliably hold the tube.

The component is, for example, a fixed glass element. In this case, the drive cable holder is fastened directly to the fixed glass element in a material-locking manner together with the guide tube. Alternatively, the component is a frame element or a plurality of frame elements fixedly connected to one another.

The shaping tool is formed, for example, from two shaping tool parts or shaping tool halves into which the above-mentioned components are inserted and positioned. The shaping tool is then closed, for example, and plastic is introduced. After hardening of the plastic, the molding tool is opened and the component is demolded and removed together with the drive cable holder.

If longitudinal slits are referred to hereinafter, perforations for longitudinal slits are likewise indicated where applicable.

According to at least one embodiment, the method has: a holding element is provided in the forming tool for holding the catheter on one side, in particular by the side facing away from the component.

The position of the catheter is held before the introduction of the plastic, i.e. the catheter is fixed in position by means of the holding element. The fixation of a single side means that the catheter is held by one side only by means of the holding element. Whereby no further holding element is required for holding the catheter from the other side. In other words, a holding element is provided in the forming tool, which holding element alone is sufficient to hold the catheter in a defined region in the forming tool. The holding element is arranged in particular on the side of the forming tool facing away from the component. It is also possible to provide a plurality of holding elements which hold the guide tube on one side in the forming tool in a point-like manner at a distance from one another. Between the holding elements, the catheter is freely accessible in the forming tool. The catheter can thus be completely surrounded by plastic in the region below the holding element, up to a complete surrounding except for the longitudinal slit or the perforation. On the holding element, the catheter is not completely surrounded by plastic, but only partially. This embodiment is particularly advantageous if the component is a fixed glass element. In such a case, the holding element for holding the tube by the second side must either remain in the component after the introduction of the plastic or it must protrude through the component in order to be able to be removed from the component later. In both cases, the visual appearance of the typically see-through fixed glass element is greatly impaired and unacceptable to the customer, let alone the possible mechanical weaknesses that in the worst case lead to glass breakage.

According to at least one embodiment, the method has:

-removing the retaining element after introduction of the plastic; and thereby

-forming a free passage to said conduit at a position of the drive cable holder corresponding to the holding element.

The retaining element is removed after the introduction of the plastic. Thereby forming a free passage to the catheter at a position of the drive cable holder corresponding to the holding element. This maintains the free channel, which however does not have an adverse effect on the stability of the drive cable holder. The holding element is formed, for example, in a conical or funnel shape. The free channel is thus shaped concave (Negativ), i.e. for example funnel-shaped, after demolding of the component.

According to at least one embodiment, the method has:

-in the case of introduction of plastic, at least partially embedding the holding element with the plastic; and thereby

-retaining the retaining element (107) in the manufactured drive cable holder.

In this embodiment, one or more holding elements remain in the drive cable holder, so that further steps, for example steps for removing these holding elements, can be omitted. The holding element does not interfere further on the basis of the single-sided arrangement on the side facing away from the component. In particular, the holding element can be covered by a veneer (Verblendung), for example a ceiling.

According to at least one embodiment, the holding element is a clamping or locking element or an adhesive tape. The clamping or locking element is locked with the tube with or after the catheter is positioned and before the introduction of the plastic. The holding element has a corresponding molding and/or a corresponding material, for example a lateral recess. Alternatively, the holding element is an adhesive tape, for example a double-sided adhesive tape, so that the holding element can be fixed in the forming tool and can hold the position of the catheter until finally the plastic is introduced into the forming tool.

According to at least one embodiment, the shaping tool has an integral holding element which is designed for holding the catheter on one side, in particular from the side facing away from the component. The method comprises the following steps:

-removing the forming tool with the integrated holding element after introducing the plastic into the forming tool; and thereby

-forming a free passage to the catheter at a position of the drive cable holder corresponding to the integrated holding element.

The forming tool itself thus has corresponding holding elements which are removed during demolding. Further, the same applies similarly to the above.

Combinations of the above embodiments of the holding element are also conceivable. For example, different holding elements can be used.

According to at least one embodiment, the drive cable holder is configured in a frame-like manner and has a longitudinal frame section which, in the intended installed state of the drive cable holder, extends in the longitudinal direction of the vehicle and is assigned to a guide rail for the shade system, wherein a longitudinal slot or perforation is configured along the longitudinal frame section. A drive element, for example the mentioned slide or block, which is directly coupled to the guide rail or is movable in the guide rail can thus be realized by the longitudinal slot. The drive cable holder is thus a one-piece frame of the component. The frame extends, for example, completely or partially along the component in the edge region of the component, for example, around a roof opening of the roof in the intended installed state of the component. For example, the drive cable holder has one or more receptacles, which are produced by a forming tool in the production of the drive cable holder. Alternatively or additionally, one or more fastening elements are positioned in the molding tool and are respectively surrounded and held by the plastic after the introduction of the plastic. The receptacle and/or the fastening element are used, for example, for coupling with a guide rail. The frame can also be used for attaching components, such as a fixed glass element, to the vehicle, wherein further receptacles and/or fastening elements can be provided for this purpose, as described above. Thus, the drive cable holder can realize a multifunctional one-piece element.

According to at least one embodiment, the guide rail of the shade system for the vehicle roof is fastened to the drive cable holder in the longitudinal frame section after the drive cable holder has been manufactured. The guide rail is thereby directly mounted on the drive cable holder, wherein the longitudinal slot or the perforation is open/oriented or accessible towards the guide rail, in particular towards the guide rail channel. Hereby it is achieved that the slider/slide is directly connected to the drive cable in the catheter for driving the slider/slide and thereby operating the shade system.

According to at least one embodiment, the drive cable holder has a transverse frame section which, in the installed state of the drive cable holder in the vehicle, extends transversely to the vehicle longitudinal direction and is formed in one piece with the longitudinal frame section. The one-piece drive cable holder thus has two sections which merge seamlessly into one another. The duct extends for example also in the transverse frame section. The transverse frame sections are for example configured to drive the cables from the electric drive to the longitudinal sections and thus to the feed region of the guide rail.

According to one configuration, a holder for a driver is provided. The holder is positioned in the forming tool prior to introduction of the plastic. Plastic is introduced into the forming tool so that if a driver holder is constructed, the plastic holds the holder. The holder is positioned in a predetermined position, in particular with respect to the component and the catheter, in which position the driver should be fitted in the completed drive cable holder. The drive is, for example, an electric drive and has, for example, an electric motor. The motor is in contact with the drive cable, in particular guided in the catheter, in a ready state, so that the drive can move the guide wire along the catheter. Alternatively, the holder is manufactured as a one-piece, integrated component of the drive cable holder. Whereby the interface for assembling the drive is integrated into the drive cable holder.

According to at least one embodiment, a plurality of conduits are provided, each configured to guide a drive cable. A plurality of conduits are positioned in the forming tool. And similarly adapted to the above. For example, the catheters are positioned side by side and/or stacked in different layers. The layers are spaced apart from each other parallel to the main extension direction of the catheter. In particular, the conduits are arranged vertically in different layers relative to each other in a ready state. This allows a small installation space requirement for the drive cable holder. Furthermore, a tight spacing of the conduits from each other can be achieved.

According to at least one embodiment, the conduits are positioned at least partially overlapping in the forming tool. Thereby, crossing and stacking of the conduits can be achieved. Thereby, a small installation space requirement of the drive cable holder can be achieved.

According to at least one embodiment, a drive cable is provided. After the drive cable holder is constructed, the drive cable is guided into the catheter. It is possible to first form a drive cable holder on the component, said drive cable holder having one or more conduits. One or more drive cables can later be simply introduced into the respective conduits.

According to at least one embodiment, the construction of the drive cable retention member includes a foam process. In particular, the plastic is foamed relative to the forming tool. The plastic is, for example, polyurethane. The conduit is covered with plastic foam in the forming tool. For example using the so-called RIM process (reaction injection moulding ) or another low pressure process. For example, two different components, for example isocyanate or polyol, are introduced in liquid form into a convection mixing head, homogenized and introduced into the shaping tool at a small pressure, for example up to a maximum of 6 bar. Where the components react to polyurethane. The conduit is not deformed based on the small pressures applied in the foam process. The conduit is for example a plastic tube. It is thereby possible to use a catheter which is flexible in bending and is relatively thin-walled. The low internal pressure in the forming tool avoids bending and deformation of the catheter in the case of forming the drive cable holder.

According to another aspect, a component for a roof of a vehicle is disclosed, having the drive cable holder according to the above-described embodiment. The embodiments, features and advantages set forth for the method apply to the component as well, and vice versa. The components substantially achieve the advantages and functions described above.

According to another aspect, a component for a vehicle roof is disclosed having a drive cable retainer. The drive cable holder has a holder body composed of plastic. The drive cable holder has a conduit at least partially embedded in the holder body. The holding body is formed in one piece and is connected to the component in a material-locking manner. The retaining body has a transverse element which extends transversely to the longitudinal direction of the vehicle in the installed state of the drive cable retaining element intended in the vehicle. The cross piece has a first contour which forms a receptacle for one or more components of the shade system, in particular for receiving a vehicle roof.

The embodiments, features and advantages set forth for the method are also applicable to the component and vice versa. The component is manufactured similarly to the method described above. The components substantially achieve the advantages and functions described above.

The component with the directly molded retaining body enables a relatively small installation space requirement and thereby enables a reliable support of the catheter. Furthermore, a flexible configuration of the position of the catheter relative to the member can be achieved. No additional fasteners are required for fastening the drive cable holder to the member. A high degree of integration can thus be achieved.

In particular, it is advantageously provided in the case of components that one or more receptacles for the shade system are provided directly during the production of the drive cable holder. Such a receptacle is thus an integrated component of the drive cable holder. And more particularly to a receiving portion that enables connection of a component to a drive cable holder. In other words, the receiving portion is a special shaping of the retaining body for mounting components, such as a vehicle roof. For example, in the case of form-locking, for example, by locking, wherein in particular no additional fastening elements are provided. For example, a vehicle roof for decorating a roof opening of a vehicle roof can be fitted into one or more receptacles in a simple manner. In addition or alternatively, a receptacle can be provided as a storage, for example for a pull-in hook (zugspriging). Additionally or alternatively, the receiving portion can be configured as a guide channel or guide rail in or on which components of the shade system can slide.

The cross member can relate to the above-mentioned cross section or a separate element. The cross member can be a cross bar or beam. The cross piece can be part of a frame which is mounted to the component, in particular foamed.

According to at least one embodiment, the drive cable holder is constructed in a frame-like manner and has a longitudinal frame section which extends in the vehicle longitudinal direction in the intended installed state of the drive cable holder. The longitudinal frame sections are formed in one piece with the transverse elements. A guide rail for a shade system of a vehicle roof is fastened to a drive cable holder in a 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 can be freely accessed, i.e. opened outwards or towards the guide rail. The rail has a second profile that forms a receptacle for one or more components of the shade system.

According to at least one embodiment, the first contour of the transverse element and the second contour of the guide rail transition into each other, in particular with respect to the shape configuration of the receiving portion. In other words, the profiles are aligned and/or arranged flush. In other words, the profiles "seamlessly" transition into each other.

According to at least one embodiment, the retaining body has a transverse frame section which, in the installed state of the drive cable holder in the vehicle, extends transversely to the vehicle longitudinal direction and is formed in one piece with the longitudinal frame section. The conduits are at least partially embedded in the transverse frame sections. In the transverse frame section, a holder for a drive of the shade system is formed. The transverse frame section is thus also formed in one piece with the transverse element.

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 a vehicle roof.

According to at least one embodiment, the holding body is elastically designed such that the drive cable holder has a head injury factor below 1500. In particular, by using PUR foam, it is possible to form the retaining body with elastic, energy-absorbing hardness, so that the retaining body is formed from plastic foam as absorber. This enables a head injury factor below 1500 in the roof region. The head injury factor (HIC, head Injury Criterion) is, for example, predetermined legally. For example, it is possible to achieve a head injury factor below 1000 with the aid of a holder made of foamed plastic. The drive cable holder thus serves not only for holding the guide tube and, if appropriate, the drive, but also as an absorber, in order to be able to achieve the desired head injury factor in the roof region. Thereby, additional absorber foam pieces that would otherwise be required can be saved, whereby assembly costs and component costs can be reduced. In addition, a high degree of integration can be achieved in this way.

The above-described embodiments of the method and the component are likewise applicable. For example, a plurality of ducts can be provided.

Drawings

Further advantages, features and developments result from the following exemplary embodiments which are explained in conjunction with the drawing. Elements that are the same, similar, or identically acting can be provided with the same reference numerals across the figures. It shows that:

FIG. 1 is a schematic illustration of components according to one embodiment; and

fig. 2 to 7 are schematic cross-sectional views of the component.

Detailed Description

Fig. 1 shows a component 100 of a roof of a motor vehicle according to an embodiment of the invention. The component 100 relates to a fixed glass element which is inserted into a top opening of a vehicle roof. The member 100 can also be a single or multi-piece top frame piece, for example made of plastic or metal such as a plate.

The component 100 has a drive cable holder 101, which is formed in one piece and is foamed directly onto a surface 102 of the component 100. Drive cable holder 100 has a holder body 103 made of plastic. The holder 103 is formed of polyurethane, for example. The holding body 103 is connected to the component 100 in a material-locking manner.

The component 100 has a shade system 104 which is arranged on the component 100 in the region of a front side 106 of the component 100 in relation to a vehicle longitudinal direction 105 (X-direction, i.e. longitudinal direction) of the vehicle in the given installed state. Shade system 104 is, for example, a roller blind structure for shade of member 100 and has corresponding components, such as a pull-behind hook, roller blind track, slider, and/or the like. In addition, the component 100 also has two longitudinal sides 107 and a rear side 108.

The drive cable holder 101 is designed as a frame and has two opposite 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 associated with a guide rail for operating the shade system 104 and are, for example, formed symmetrically to one another. Furthermore, drive cable holder 101 has a transverse element 111 which is arranged offset in the region of rear side 108, approximately parallel inwards with respect to transverse frame section 110. All of the sections of drive cable holder 101 are formed in one piece and foamed onto component 100.

Drive cable holder 100 has one or more conduits 112, as will be described further below. The catheters 112 are each configured to guide a drive cable through which the shade system 104 can be operated. The drive cable is driven by a driver 113.

The holding body 103 is composed in particular of foamed plastic 114. The holding body 103 is produced by means of a foam process, wherein a relatively low pressure of up to a maximum of 6 bar is present in the forming tool. In the case of foaming in the forming tool, the plastic 106 expands, correspondingly surrounding the component in the forming tool. The plastic part produced by injection molding can thereby be dispensed with. The holding body 103 is produced in particular without the aid of an injection molding process in which a relatively high internal pressure is present in the molding tool. A relatively high internal pressure may, for example, lead to: the relatively thin walled tube 112 bends and deforms.

Additional details are described below with respect to fig. 2-7, each of which all show schematic cross-sectional views of the component 100 in different positions.

Fig. 2 shows a section X-X in the transverse frame member 110, wherein two ducts 112 are held side by side in the holding body 103. The conduits 112 are, for example, plastic tubes each and are connected to the holding body 103 in a material-locking manner. The holding body 103 completely surrounds the catheter 112 in sections to hold the catheter 112. In particular transversely to the vehicle longitudinal direction 105, the guide tube 112 is completely surrounded by the retaining body 103 in each case in a sectional manner radially.

The guide tube 112 is held by fastening the guide tube 112 directly in the foamed plastic 114 of the holding body 103, without the guide tube having to be introduced into the holding body 103 at a later time. Thereby, a structure aid for introducing the catheter later can be omitted. This enables smaller installation space requirements and is generally less expensive to manufacture and assemble and thus more efficient. The installation space required for the component 100 and the drive cable holder 101 is reduced here. This increases the perspective of the component 100 as a fixed glass element. Where the area occupied by the member 100 within the top opening is reduced.

The conduits 112 can be arranged side by side or overlapping or offset from each other. The holding body 103 is sufficient to support the guide tube 112 after the plastic 114 has hardened, so that a reliable guidance of the drive cable is achieved during operation. The tension and/or compression forces are reliably supported.

In the illustrated foam process, the plastic 114 expands in the forming tool such that the plastic adequately surrounds the conduit 112 to retain the conduit. It is also possible here for three, four or more tubes to be arranged in an overlapping manner at small intervals, since the plastic can also enclose such a geometry by means of foaming. The conduit 112 must be held in only a few small positions in the forming tool during the foam process. In the remaining region, the plastic 114, after hardening, radially completely surrounds the catheter 112.

Drive cable holder 100 is correspondingly formed according to section X-X on the other side of drive 113.

Fig. 3 shows by way of example: how the guide tube 112 is held in the forming tool in the manufacture of the holding body 103. For this purpose, a holding element 115 is provided. The holding element is arranged fixedly in the forming tool and holds the guide tube 112 on one side, i.e. by the side facing away from the component 100. For this purpose, the holding element 115 has a lateral recess 116 for the locked holding of the catheter 112. Such as the holding element 115, is realized as a clip.

In the molding tool, the guide tube 112 is held in each case in a point-like manner by a plurality of holding elements 115. The holding element 115 can be an integral part of the forming tool or a separate element. The retaining element 115 is removed, for example, after the plastic 114 has hardened. A free channel 117 to the catheter 112 is formed in the finished holding body 103 at a position corresponding to the position of the holding element 115. The free channel is however only formed in a small part of the catheter 112, so that sufficient support for the catheter 112 is provided by the retaining body 103.

Alternatively or additionally, the holding element 115 remains in the finished holding body 103 and thus in the drive cable holder 100.

Fig. 4 shows a section A-A through the longitudinal frame section 109, wherein two ducts 112 are stacked. Furthermore, the guide rail 118 is fitted 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 shade system 104 is movably supported. The downcomer 112 has a longitudinal slit 121 along the longitudinal frame section 109. The longitudinal slit 121 opens towards the rail channel 119 so that the drive cable and the slider 120 can be coupled directly and over a short distance. The longitudinal slit 121 extends at least over a length corresponding to the movement of the slider 120.

The longitudinal slot 121 is already provided in the production of the drive cable holder 100, i.e. the guide tube 112 is positioned together with the longitudinal slot 121 in the forming tool, wherein the longitudinal slot 121 is sealed or covered when the plastic 114 is introduced, so that the plastic 114 cannot flow into the guide tube 112. This enables the advantages and functions mentioned at the outset to be achieved.

Fig. 5 shows a section B-B through the longitudinal frame section 109, which is substantially similar to section A-A, with the addition that the fastening of the guide rail 118 is shown. For this purpose, the fastening reception 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 with the holding body 103 in the longitudinal frame section 109. The fastening receptors 122 are manufactured in a foam process. The threaded insert can be installed before and after foaming. A variety of additional configurations for fastening are also contemplated.

Figures 6 and 7 show sections C-C and D-D through the cross-piece 111 in two different positions. The cross member 111 has no conduit. The transverse element 111 has, in a defined position, a first contour 123 according to the section C-C, which forms a receptacle 124 for one or more components of the shade system 104. The receiving portion 124 is in particular configured such that the ceiling can be connected to the cross piece 111 in a form-locking manner, in particular without further fastening elements. Furthermore, the first profile 123 of the transverse element 111 is configured in the section C-C such that a support 125 for the hook frame 126 is formed. In other positions, the cross-piece 111 is configured according to the section D-D such that only the support portion 125 is formed.

As can be seen from fig. 4 and 5, the rail 118 has a second contour 127, which likewise forms the receiving part 128, so that the ceiling can also be fastened to the rail 118 in a form-fitting manner. The first and second profiles 123 and 127 can transition into each other, for example, seamlessly.

The fastening of the ceiling to the cross-piece 111 and the guide rail 118 allows for a particularly simple and space-saving compact construction.

The driver 113 is fastened, for example, to a holder (not explicitly shown), which is an integrated part of the drive cable holder 100. The holder is, for example, part of the holder body 103 and has a corresponding profiling. Alternatively, the holder is co-located in the forming tool like the catheter 112 in the production and is connected to the holder body 103 by the introduction of plastic 114, for example, by material-locking. Thus, for example, the drive cable holder 100 is molded directly onto the component 100 together with the holder and the guide tube 112. A plurality of holders and drives can also be provided.

The manufacture of the members together with the drive cable holder is discussed briefly again below. The component 100 is introduced into the forming tool together with the conduit 112 and, if necessary, further components, such as the holders mentioned and further conduits. The catheter 112 is held in a predetermined position relative to the member 100 by a holding element 115. The inner wall of the forming tool has a shape which is then intended to face the holding body 103. The plastic to be foamed, which is composed of a plurality of components, for example, is then introduced into a forming tool. In particular, the plastic 114 is introduced into the forming tool at a low pressure of below 10 bar, in particular at a pressure of between 1 bar and 6 bar. Where the components react and foam into polyurethane. In this case, the plastic 114 expands, so that it surrounds the conduit 112 and forms a material-locking connection with the component 100, in particular on the surface 102.

A cost-effective production and a high degree of integration can be achieved by the direct foaming of drive cable holder 101 on component 100.
