GUIDE AND METHOD FOR MANUFACTURING A GUIDE RAIL FOR A BOWDEN CABLE OR PIPE LIGHTING OF THE INVENTION Description of the invention The invention relates to a guide rail for a Bowden cable or tube lifter according to the preamble of claim 1, as well as to a method for manufacturing a guide rail for a Bowden cable or tube lifter according to the preamble of the claim . Metal guide rails are known for cable lifters whose surfaces are partially coated which are an integral part of a structural assembly of the window lifter, which must be assembled and assembled accordingly. Depending on the metal used and the number and type of the assembly and assembly processes, the structural assembly manufactured in this way is heavy Lativame. Through each manufacturing process used for the individual parts and eventually the surface coatings, and through each assembly and assembly process emploco increase the chances of errors that can negatively influence the quality of the glass lifter. • Due to the relatively complex manufacturing process and coupled with the expense of development and quality assurance, manufacturing costs are high. By virtue of the mismatching of the unfavorable shapes between the metal surfaces of the guide rails and the derailing pieces for guiding the crystal, it becomes necessary to further lubricate the surface < contact and eventually cover the guide rail. From the document DE 41 31 098 Cl, a guide rail for cable risers is known, whose inversion zones are provided for at the same time fixing the guide rail to the internal metal sheet of the door. For this purpose, a fastening bolt is guided through the cable inverter, for example a sheave, and is connected to the internal metal foil of the door. By means of this it is possible to introduce the fl ick of force directly into the body of the door without an inversion through the guide rail, so that the guide mainly has to pay attention to the transmission of transverse forces to the guide. whipping the door. In this context, it is proposed to replace the metal guides that are used up to now by synthetic rubber rails. No detailed specifications were given regarding the constructive structure of the synthetic material guide rail. To mount i. n window glass and .n window lifter in a vehicle door, for < ± document EP 0 561 440 Al a mounting bracket is known made of a piece of synthetic material and having a central fixing plate to house the glass lifter and several hollow holes that start as a star from the central fixing plate and join one piece with the one in which The ends are also provided with a guide piece for accommodating the window pane amounts. The hollow rays comprise several fastening clips integrally connected to them which serve to fix the mounting bracket to the door of the vehicle. The window channels for the window for receiving the window edges of the window are limited by p. spaced apart side walls constituted by vari s tabs projecting from a base and arranged alternately transposed with respect to each other. In the guide channels of the window, an elastomer slide is inserted between the tabs in order to improve the sliding ability when guiding the crystal chants of the window. As an alternative, it is proposed or manufactured the window sleeve of a separate synthetic material window with metallic sliding strips that are properly fixed to the ends of the hollow rims of the mounting bracket. The necessary rigidity of the mounting bracket1 knew what is established by the shape of the hollow rays as well. as by means of a central "cross-member of the fastening element". The mounting bracket of known synthetic material has a "complex" shape that can only be manufactured with a considerable expense to respect the narrow manufacturing tolerances. The requirements that are conditioned by the task are demanded to the qualities of resistance and conduction that a module can only satisfy the glass ceiling module in a limited way. known assembly, so it is necessary to adopt additional measures to increase the rigidity and to improve the sliding qualities in the guide channels that house the window glass. By the writing (ie patent US 4,835,907) it is known a guide rail for a window lifter comprising a longitudinally extended guide zone for driving a cable and in which an inversion sector for the cable driven in the guide zone is provided at the ends of this area of: juia . These investment sectors are used to deflect the cable towards a drive. In the investment sectors, the cable is in each case guided in a curved groove in which a synthetic material element is additionally inserted to improve the sliding qualities. The investment sectors also serve as fixing areas to fix the guide rail to the vehicle door and have the reinforcing rtents. EP 0385 167 A1 discloses a Cement reversing part for a Bowden tube lifter which is fixed at the ends of a profiled rif-1 made of metal or synthetic material and comprises an angled side wall. The task of the present invention is to specify a guide rail for a method for the manufacture of a guide rail for a cable or Bowden cable guardrail of the type under consideration that conforms to the use of synthetic material. This material is solved by means of the characteristics of claim 1 with respect to the guide rail and by the features of claim 19 with respect to the manufacturing method. The guide zone of the guide rail is made of synthetic material, and the guide rail includes an independent reinforcement element with unique reinforcement elements to the driving area that will guide the The longitudinal direction of the rail extends over the central portion of the driving zone and also covers the area of the guide rail.

Since the guide rael is made up partly or totally of synthetic material L and that by means of the structural subdivision of the guide rail in a zone of conduction that pr Lmordial nente assumes the task of a guide 5 of sliding and a reinforcing area that occupies of the resistance to inflexion and torsion required and that assumes primarily the mechanical support functions of the guide rail, the gu._a rail can be designed with a view to being distinguished by a low weight and low overhead costs. manufacture. Through the fact that this allows to integrate several functions that up to now were manufactured most of the time of several individual pieces that then had to be assembled, it is also possible to exclude or decrease the possibilities of error and consequently improve in total the quality of the structural unit. The structure according to the invention of a guide rail for a Bowden cable or tube lifter complies with both the mechanical efforts of a guide rail in the Regarding rigidity to inflection and torsion, Coiro also satisfies the tribological requirements that are demanded by a guide rail in terms of resistance to abrasion, good sliding properties to drive the crystal and noise generation as low as possible. possible.

By means of the at least partial material synthesis of the r? < guide (in particular of your driving area) you can take advantage of the greater design freedoms offered by the construction of parts of synthetic material. By means of the coordination of friction matings specially adapted tribologically from the synthetic materials, between the conduction zone of the rail and the sliding part to drive the crystal, the possibility of operating this friction mating without additional lubrication is created and thus obtain economically and technologically a better product i. Preferably the dorsal faces of the sliding surfaces of the driving zone do notThey connect directly with the reinforcement elements, so that the necessary but also sufficient separation between the conduction zone and the reinforcement area is guaranteed. Consequently, the reinforcement elements can be provided in all the areas of the guide rail except for the area of the sliding surfaces, that is to say in the passage area of the window pane dragging part. The front face of the sliding surfaces or zones establishes contact thereon with the glass window or sliding parts.

The reinforcement elements are preferably constituted by ribs and / or webs which are molded on a surface of the reinforcement area, preferably integrally and substantially perpendicular to the surface 5 of the reinforcement area. The nerves and / or souls can be configured in particular as a pattern of rhomboidal patterns in relief or cross rib. Alternatively, the reinforcement elements can be constituted by hollow profiles. By means of the arrangement of the reinforcement elements such as ribs, al'aas or hollow profiles in the reinforcing area, a favorable rigidity-mass ratio is obtained. Preferably around the points of introduction of force, for example in the field of fastening points to join the guide rail with an internal metal sheet, a door module or the like and / or around fixing points for additional components such as window risers, cable reels or similar. - have nerves and / or souls that start by way of rays from the points of introduction of force. By this the forces starting from the fixing points are introduced directly into the cross-rib structure of the reinforcement area, so that also in these necessary weak points the stability of the guide rail is guaranteed. The subdivision of the guide rail into a reinforcing area and a conduction zone generates the prerequisite for the reinforcement area to be made of a synthetic material with high mechanical resistance, the conduction zone of a synthetic material with good tribological qualities, being that both zones are integrally linked with one another thus giving a structural unit result. By manufacturing the guide rail according to the process of injected casting of two or more components, the subdivision of the guide rail can be carried out in a reinforcement area with a high strength material and high modulus E and a conduction zone with cents, nerves or Driving elements of a technically favorable material optimized for low friction coefficients, low abrasion wear and low noise level. That is, the conduction and reinforcement functions are structurally separated, being that the conduction zone (which in a particularly favorable form is extruded, compressed or molded of synthetic material) is made without reinforcement elements and can be spatially separated from the areas subjected to greater mechanical area (reinforcement area), the reinforcing elements being provided only in the reinforcement area. In this, it is convenient to connect the driving zone to the reinforcing area by means of a short lever arm and to select at least partially a greater thickness of material, preferably the reinforcement area is configured according to the principle structure of curved beams and additionally comprises fibers that reinforce the synthetic material, in particular glass fibers or carbon fibers The central part of the reinforcing area has, for example, a greater cross section than its ends. guiding rail with a metal profile, the reinforcement area of the rail is made of metal, while the conduction zone is made of synthetic material due to the best tribological qualities, in this the reinforcement area is constituted by a profile metal with favorable mechanical properties and is characterized by a high resistance moment with relatively low weight. The synthetic material is connected in a form and / or force manner with the profile metallized, for example by covering, totally or partially by injection, the metal profile forming the support structure, by co-extruding the synthetic material on the profile Z ^ ^ TZTZ ^, - _?; Z.% £ • metallic or by means of a later assembly of the synthetic material and the metal by gluing, welding, lubrication or insertion. By covering the metallic profile around the medically friendly material before injection, the synthetic material, in addition to the conduction function, also contributes to the localized reinforcement of the metallic profile by producing a hybrid structure mediance ribs and reinforcements, which is both rigid to the bending as well as torsion. In this way it is possible to transform with the nerves of synthetic material or the structure of | synthetic material, a simple metallic profile rigid to the f? = x? on in a functional element rigid to torsion and bending. In addition, the metal profile can be inserted in the n channel of the body1 of the synthetic material of the gui rail; Alternatively, it is possible to inject a structure of smtetn material or to improve the torsional stiffness in the metal or rigid flexion profile. Since, for example, a U-profile is not very rigid to the torsion, by means of the injection K, a structure of synthetic material the profile is made rigid to the torsion to be weighed < e that the amhetic material itself is used in particular because of its good psychological properties.

The conduction zones in the form of webs, ribs or conducting elements can be coated with a lubricating lacquer or coated under vacuum or plasma with a suitable substrate, for example by chemical vapor deposition coating. plasma, to improve the tribological properties. In this the lubricating lacquer can also be used on synthetic material if the synthetic material with good mechanical strength qualities has- especially carca capacity but not particularly good tribological qualities. An improvement of the tribological qualities as well as the mechanical properties can be achieved by a cross-linking of the molecular structure of at least the surface of the material used, for example through the effect of suitable chemical means or through ionizing radiation,? - n special radiation of rayes range. A thermoplastic material is at least partially transformed to the thermoset state. The strength and rigidity of the material rail synthetic can be; increase through the use of special tooling and process techniques, for example through the application of cascade casting system, by which unwanted joining seams are avoided, or by symmetrical injected cast iron materials reinforced with fibers or chain type larca saturation, through which "Uria mayer orientation of the molecular structure and with it a higher E-module." Contrary to the continuous metallic profile, the The reinforcing area can be configured so that the cross section is designed to be adapted correspondingly along the length according to the bending moment that occurs. To manufacture the rail made of synthetic material _e can employ an injection process or internal pressure of gas if thermoplastics reinforced with long glass fibers are used in order to make the most of the properties of the material and to manufacture in a particularly poor manner. deformation. To make the synthetic material rail also mechanically resistant without a complex tooling technique and yet produce a surface favorable to friction matings on the surface. can conveniently apply the injection of 2 components in the overmolding process. The surface, in particular the zone of: onduction exposed to the plastic frame, can be configured in this way with a reinforced material and in cavity the core with a reinforced material per fibers.

By means of the realization examples that are represented in the drawing, the idea on which the promotion is founded will be explained in more detail. They show: figure 1 unites) plan view on a guide rail with a driving area, a reinforcement area as well as fixation points and articulation; 2 shows a side elevational perspective view of the guide rail according to FIG. Fig. 3 a < orte through the guide rail along the line III-III of figure 1; Fig. 4 a < orte through the guide rail along the line IV-IV of figure 1; 10 shows a section through the guide rail along the line V-V of FIG. 1; 6 is a schematic representation in section of a metal profile partially wrapped in synthetic material applied by injection; Figure 7 is a schematic side elevational view, and Figure 8 is a schematic top view on a guide rail with longitudinal dilatation areas between the reinforcement area and the fastening sector. 20 The guide rail 10 shown in Figure I? P. a plan view, in figure 2 in a perspective in side elevation as well as z figures 3 to 5 in several sections, with base plate or assembly point 4 formed in one piece for a cable reel and dots 25 34 to 36 of articulation for a bearing cap or, n levariscrisis drive is made entirely of synthetic material or a metal profile partially wrapped in synthetic material applied by injection, depending on the design, choice of material and composition previously described material. The guide rail 10 is subdivided into a driving zone 1 and a reinforcement area 2 and comprises two fixing brackets 31, 32 in which it is attached to the fixing bracket of a vehicle door, for example with a support plate or an internal metallic lamella of the door. The driving zone 1 has an anterior sliding surface 11 and a rear sliding surface 12 for accommodating a sliding or sliding part of the window pane that slides along the longitudinal direction of the guide rail 10 on the surfaces 11. , 12 < and sliding by grabbing them in shape drag. Reinforcement area 2 has reinforcement elements 20 which stand perpendicular to the surface of reinforcement area 2 and which form a pattern of rhomboidal patterns in relief or in a cross rib. As can be seen in particular by the sectional representation in figure 3 along the line III-III and in figure 5 along the line VV according to figure 1, the driving zone 1 joins with the reinforcement area 2 to v- _3fe »" B¿H? - ^ by means of a short lever arm 9, so that a high moment of resistance is guaranteed against an inflection of the zone 1 c as a consequence of the driving element which is it slides along the 5 surfaces 11, 12 of "lizamiento" with the glass of the fixed window. Figures 1, 3 and 5 further clarify that the sliding surface 12 that forms the dorsal face of the conduction surfaces of the conduction zone is not bonded to the reinforcing elements 20 of the reinforcing area 2 configured as ribs or webs, by virtue of which an additional web 9 is disposed between the conduction zone 1 and the reinforcement area 2 that joins them in a single piece. Mount point 4 adjacent to area 2 ce The reinforcement has a multit id of nerves or webs 40 that stand out perpendicular to the lower base of point 4 of the assembly, which is d. They partially sponge lightning bolts around joints 34 to 36 for a bearing cover, a spring lifter drive or similar and of this season take care of an optimal transmission of force on the reinforcing area 2. Likewise, the ribs or souls that extend parallel serve to increase the consistency of the structure of the rail 10 guide.

The mounting point 4 has an interior: 0 hollow cylindrical as a pair of a drive box from which 2 rails 51, 52 insert for a drive cable whose Bowden casing is umoa to the access box by Bowden supports 53, 54. 11 drive cable is attached to the drive element which is guided in a displaceable manner on the zone 1, the conduit in each case through a super-investment and a lower one in the sector of the fixing points 31, 32 . Inside the hollow cylindrical cylindrical box of the drive is inserted a drum for cable whose external cylindrical surface is provided with cable guides to house the drive cable. A further fixing point 33 serves to connect articulatedly to the mounting point 1 or to additionally support the guide to the fixing base of the vehicle door, that is to say a support plate, an internal metal foil of the vehicle. the door or a door module in which in the necessary connection it is also possible to integrate the guide rail 10. The guide rail shown in FIGS. 1 to 5 can be manufactured entirely or partially from the synthetic material with the structural characteristics and compositions of the synthetic material described above. Through the sIndivision of the guide rail in a ~ * - $ t-zone of conduction and ur area of reinforcement and it is possible to select an injection molding method of two or more components in which the reinforcement area is constituted by a high strength and high-modulus material E, and for In the driving zone, a optimally optimized material is selected, with the aim of obtaining low friction coefficients, little abrasion and an o? Noise level. In an alternative embodiment, the reinforcement area of the guide rail can also be fabricated from a metal profile with a favorable face-mechanical texture which guarantees a relatively low weight moment of resistance, while the area of driving because of the best tribological characteristics consists of synthetic material. Both areas can be joined to one another in drag and form, for example by surrounding the metal profile with a synthetic material which, in addition to the function of conduction, also contributes to the additional localized reinforcement of the metal profile when it is produced. by ribbing and stiffening is a hybrid structure that is both resistant to torsional bending, a structure of this type is shown in figure 6 and shows a metallic profile partially surrounded by myeccioi with a material 6 synthesized, , - ....,, w ^ -. , > ^ & mumm & waB »a) amm? s! é¡ & jz-. , ^ r. ~ ¿: * Z 1"_¿, ^" a ** ". specifically where the driving or sliding surfaces 11, 12 require it, and additionally in the zone of reinforcement area 2 to further reinforce the metal profile as well as to form-fit the material 6 synthetic with metallic profile 7 for reasons of injection technique. Alternatively to the above, the joint between the profile and the metal and the synthetic material can be made by coextrusion or subsequent assembly in the form of gluing, welding, gluing or insertion. Both in the assembly according to FIG. 6 and also in the finished arrangement described according to FIGS. 1 to 5, it is also possible to cover the driving zone 1 with a lubricating lac or with a suitable substrate for vacuum or plasma measurement. , in order in this way to further improve the tribological properties of the driving zone 1.
