Definitions
- This invention relates to a motor vehicle window lifter with a twistable or bendable guide rail according to the generic part of claim 1 and to several methods for attaching a twistable or bendable guide rail to at least one carrier, which are formed according to at least one of the apparatus claims.
- the fastening points of the vehicle door lie in planes which intersect each other such that they include an obtuse angle with each other, with the sectional lines of the planes extending vertically or parallel to the direction of travel of the motor vehicle, i.e. in direction of the Z-axis or X-axis.
- the twist and/or bend of the guide rail of a window lifter which is arranged in a door gutter of the vehicle door, need not be accomplished before mounting the guide rail on the vehicle door or on a carrier mounted on the vehicle door.
- the guide rail no longer must be twisted or bent during press forming, but the straight guide rail, which can simply and easily be manufactured for example by extruding or roller burnishing, is only twisted and/or bent by bracing the fastening points of the guide rail with the fastening points of the vehicle door, which provides for an inexpensive manufacture and assembly of a window lifter into a vehicle door.
- door systems or door modules which contain an assembly carrier on which functional components, for example a window lifter unit, a loudspeaker, a side airbag, a door lock arrangement or the like are arranged, or a base plate for a window lifter unit, in order to create a pre-mountable, pre-checkable unit which can easily be mounted on a vehicle door.
- the base plate or the assembly carrier carries at least one guide rail, on which a driver connected with a window pane is guided.
- Such door systems or door modules are used in all kinds of designs in different vehicles and vehicle types of a vehicle manufacturer, wherein each variant of a vehicle type necessitates a specific, individual formation of the door system or window lifter, because the vehicle doors of the different variants and vehicle types are formed differently and differ in their constructive design and configuration.
- window panes with different kinematics i.e.
- An essential advantage of determining the pull-off kinematics of a window lifter only during installation of a guide rail or an assembly carrier or a base plate with integrated guide rails into a carrier element or a vehicle door consists in that proceeding from easily and inexpensively manufacturable semifinished products the guide rails or the base plates with integrated guide rails can be adapted to the respective conditions of the vehicle door, namely as regards the required bending radius (pull-off line of the window pane) and/or the required twist of the guide rails.
- the invention allows the use of parts according to the invention for use across all model ranges.
- the subject-matter of the present invention not only utilizes the ends or end regions of a straight guide rail as fastening points, which due to the connection with correspondingly aligned fastening receptacles of the carrier bend and/or twist the guide rail in a specifiable manner on bracing with the carrier, but due to the arrangement of at least one supporting point between the fastening receptacles of the carrier a measure is created which has a shaping effect on the curvature and/or twist of the guide rail during bracing of the guide rail with the carrier element.
- carrier element is understood to be the door body of a vehicle door accommodating a window lifter, in particular a door inner panel, a carrier plate insertable into the door frame of a vehicle door or a function carrier for module doors or door systems.
- supporting point also includes a supporting region and hence not only a point- or line-shaped support, but also a planar support.
- the arrangement of at least one further fastening and/or supporting point between the fastening receptacles of the carrier element provides for not only bending or twisting a substantially straight, in particular extruded or roller-burnished, guide rail when bracing the guide rail with the carrier element by supporting the guide rail on the supporting point and attaching the same to the fastening receptacles of the carrier element, but also bend up a guide rail pre-bent with a first bending radius to a second bending radius, which is greater than the first bending radius, by supporting and/or attaching the guide rail to the supporting point and attaching the same to the fastening receptacles of the carrier element, and/or twist the same in a specifiable manner.
- one and the same guide rail can be used for different vehicles and vehicle types with different window capstans or window curvatures and different strokes by corresponding cutting-to-length of the extruded or roller-burnished guide rail.
- the use of the same guide rail for left and right front and rear doors of a vehicle is possible.
- a pre-bent guide rail can also be straightened by supporting the guide rail on the supporting point and attaching the same to the fastening receptacles of the carrier element, so that the guide rail for example is attached to the supporting point under pretension, in order to establish a non-positive or integral connection of the guide rail with the supporting point by gluing, welding or the like.
- the guide rail can be braced both with a carrier plate or a function carrier as carrier element and also directly with the vehicle door, in general with the door inner panel.
- a further design variant consists in providing at least one fastening receptacle on the vehicle door as carrier element and at least one fastening receptacle on a carrier plate to be connected with the vehicle door or a function carrier as carrier element, wherein the fastening receptacles of the carrier plate or the function carrier and the vehicle door correspond with corresponding fastening points of the guide rail.
- Bracing the guide rail both with a carrier plate or a function carrier and with a vehicle door accommodating the carrier plate or the function carrier as carrier elements provides for pre-bending or pre-twisting the guide rail when bracing the same with the carrier plate or the function carrier, and for bracing the same to the final bending radius or the final twist when inserting and connecting the same with the vehicle door as carrier element.
- the type and shape of the fastening points of the guide rail and the fastening receptacle of the carrier element and of the supporting point or supporting points permits a multitude of variants which can be adapted to the respective requirements as to the shape, i.e. bend and/or twist, or bracing of the guide rail with the carrier element or the carrier elements.
- a connection is suitable in which a first fastening receptacle of the carrier element is formed as hook or pocket protruding from the carrier element, into which an end of the guide rail can be put, and a second fastening receptacle consists of a clip protruding from the carrier element, which engages behind the guide rail via an opening in the guide rail.
- connection of the first carrier element with the guide rail pre-mounted thereon with the vehicle door as second carrier element can be effected in the usual way via a screw connection, wherein for sealing an opening provided in the door body a circumferential seal is provided between the edge of the carrier plate, the function or assembly carrier and the opening edge of the door body.
- the guide rail is held in the preassembly position by putting the one end of the guide rail into the pocket of the carrier plate and by the clip connection and is fixed in X-, Y- and Z-direction and pre-bent to a first bending radius, while in the subsequent final assembly for example by connecting the other end of the guide rail with the bodyshell of the vehicle door a further bending radius is generated or a defined radius of the preferably extruded or roller-burnished guide rail is generated after attachment to the door bodyshell.
- the fastening receptacles of the carrier element can consist of a carrier element hook protruding from the surface of the carrier element and a clip
- the fastening points of the guide rail can consist of a guide rail hook, which engages behind the carrier element hook, and a clip protrusion cooperating with the clip of the carrier element, wherein the connecting elements are formed such that after putting the guide rail hook into the carrier element hook the guide rail can be pivoted about the positive connection of the guide rail hook and the carrier element hook, until the clip protrusion of the guide rail snaps into the clip of the carrier element.
- a plug-in opening of the carrier element hook is created for receiving an elongated guide rail hook for a larger undercut and hence for an optimum stability.
- connection of a guide rail with a carrier element for twisting and/or bending the guide rail by bracing the fastening points of the guide rail with the fastening receptacles of the carrier element with at least one supporting point between the fastening receptacles of the carrier element are:
- a plastic guide rail or a plastic carrier element preferably consists of a thermoplastic and/or thermoset material, which are used with and without reinforcing materials or fillers, such as for example a glass-fiber reinforced thermoplastic material.
- Manufacturing a plastic guide rail is effected by extrusion, injection molding, deep drawing, blow molding or pressing
- manufacturing a plastic carrier element is effected by injection molding, deep drawing, blow molding and pressing
- manufacturing a metallic guide rail is effected by roller burnishing, press forming or extruding
- manufacturing a metallic carrier element is effected by press forming or die casting.
- a cassette which accommodates a cable pulley holder or a cable pulley of a cable window lifter deflecting a window lifter cable, can be integrated into the connection of the guide rail with the carrier element, for example a door inner panel or a carrier plate or a function carrier.
- the cassette preferably includes two bearing surfaces forming a rear grip of the cassette on the guide rail, via which the cassette is connected with the guide rail, and by a cutout in the guide rail is connected with the cable pulley, a stepped pin with internal thread, on which the cable pulley is mounted, and with the carrier element, in that a screw put through an opening of the carrier element is screwed to the internal thread of the stepped pin.
- the cassette either is supported on the carrier element and hence loaded via the bearing surfaces, or the bearing surfaces are spaced from the carrier element, while the bottom of the stepped pin with internal thread rests against the carrier element and thereby relieves the cassette.
- a door module or door system for a vehicle door with an assembly carrier or a window lifter base plate with at least one bendable and/or twistable guide rail integrated into the assembly carrier or the base plate for guiding a driver to be coupled with a window pane along an adjustment direction.
- This expansion of the solution according to the invention for individual guide rails of a window lifter to base plates (or assembly carriers) with at least one guide rail integrated into the base plate thus also provides for twisting or bending the guide rail when mounting the base plate in the door bodyshell of a vehicle door and hence for using a base plate for different vehicles and vehicle types of different vehicle manufacturers as well as for a compensation of tolerances when mounting the base plate in the door bodyshell of the vehicle door or a compensation of manufacturing inaccuracies.
- the base plate and the guide rail are made such that the guide rail is bendable about the longitudinal vehicle axis (X-axis) and twistable about the vertical vehicle axis (Z-axis).
- the rigid region of the base plate preferably is arranged between the guide rails, while the fastening points are provided at the ends of the guide rails and at least one supporting or further fastening point is provided between the end-side fastening points of the guide rails.
- This first embodiment of a flexible base plate provides for a relatively stiff design of the guide rails without impairing the possibility of bending and/or twisting the guide rails for realizing different pull-off kinematics when connecting the base plate with the door bodyshell of a vehicle door.
- the base plate alternatively includes two guide rails whose middle regions are connected with each other via a rigid cross-beam at whose ends fastening points are arranged, which are connected with the door bodyshell of a vehicle door, so that the ends of the guide rails are without connection to the rigid cross-beam and a flexibility of the guide rail legs hence is obtained.
- the fastening points are at least partly arranged on the axles of deflection pulleys of the window lifter for guiding and deflecting a window lifter cable.
- the possibilities of mounting a base plate into the door bodyshell of a vehicle door are expanded, in that for example an opening in the door inner panel of a vehicle door is covered, which has such a size that the connection of the base plate with the door bodyshell only is possible at the outer ends.
- components integrated into the door bodyshell of the vehicle door such as crash barriers can also be used as supporting points.
- the connecting portions of the base plate are formed as struts which are connected with the ends and a middle portion of the guide rails.
- connecting portions as struts, in particular as diagonal and transverse struts, instead of a full-surface formation of the connection of the rigid middle region of the base plate with the guide rails on the one hand creates a saving of material and on the other hand the prerequisite for a selective arrangement of flexible regions in the struts, in order to achieve a defined flexibility for bending and/or twisting the guide rails.
- the flexibility required for bending and/or twisting the guide rails can be achieved in that the diagonal struts connected with the ends of the guide rails or the transverse struts connected with the middle portions of the guide rail contain the flexible regions.
- the arrangement of the flexible regions in the diagonal struts ensures a high flexibility in the end regions of the guide rails
- the arrangement of flexible regions in the transverse struts provides for a high flexibility of the guide rail in the middle region with a relatively rigid formation of the end regions of the guide rails.
- the flexible regions can be manufactured in different ways, namely:
- the base plate is formed as mounting frame with connecting portions on whose end regions articulations are arranged for accommodating guide rails for different window lifters, window lifter types and/or vehicle doors, wherein the mounting frame preferably is formed X-shaped with a rigid, middle region and four diagonal struts each extending diagonally from the rigid middle region, whose ends are angled and include variable articulations for accommodating different guide rails.

Abstract

Between the fastening receptacles 41 of the carrier element 2 at least one supporting point 61 is provided. When bracing the fastening points 51 of the guide rail 3 with the fastening receptacles 41 of the carrier element 2, the guide rail 3 supports on the supporting point 61 and twisting of the initially straight guide rail 3 with a specified degree of twisting and/or bending of the guide rail 3 with a specified bending radius R is effected.
Description
- This invention relates to a motor vehicle window lifter with a twistable or bendable guide rail according to the generic part of
claim 1 and to several methods for attaching a twistable or bendable guide rail to at least one carrier, which are formed according to at least one of the apparatus claims. - From DE 199 42 643 C2, there is known a method for attaching a cable window lifter to a vehicle door as well as the vehicle door of a motor vehicle, which contains a cable window lifter with a twistable or bendable guide rail which shiftably supports a driver to be coupled with a window pane and at its ends includes fastening points which are braced with fastening points of the vehicle door. By bracing the fastening points of the guide rail with the fastening points of the vehicle door, twisting of the initially straight guide rail with a specified degree of twisting and/or bending of the guide rail with a specified bending radius is effected. The fastening points of the vehicle door lie in planes which intersect each other such that they include an obtuse angle with each other, with the sectional lines of the planes extending vertically or parallel to the direction of travel of the motor vehicle, i.e. in direction of the Z-axis or X-axis.
- Since the degree of twisting and/or the bending radius of the guide rail required for guiding a window pane solely is achieved by the bracing of the fastening points, the twist and/or bend of the guide rail of a window lifter, which is arranged in a door gutter of the vehicle door, need not be accomplished before mounting the guide rail on the vehicle door or on a carrier mounted on the vehicle door. Thus, the guide rail no longer must be twisted or bent during press forming, but the straight guide rail, which can simply and easily be manufactured for example by extruding or roller burnishing, is only twisted and/or bent by bracing the fastening points of the guide rail with the fastening points of the vehicle door, which provides for an inexpensive manufacture and assembly of a window lifter into a vehicle door.
- Beside a use of individual guide rails in a window lifter mounted in a vehicle door, there are also used door systems or door modules which contain an assembly carrier on which functional components, for example a window lifter unit, a loudspeaker, a side airbag, a door lock arrangement or the like are arranged, or a base plate for a window lifter unit, in order to create a pre-mountable, pre-checkable unit which can easily be mounted on a vehicle door. As parts of a window lifter unit, the base plate or the assembly carrier carries at least one guide rail, on which a driver connected with a window pane is guided.
- Such door systems or door modules are used in all kinds of designs in different vehicles and vehicle types of a vehicle manufacturer, wherein each variant of a vehicle type necessitates a specific, individual formation of the door system or window lifter, because the vehicle doors of the different variants and vehicle types are formed differently and differ in their constructive design and configuration. In different vehicle doors, for example, window panes with different kinematics, i.e. different radii of curvature, different pull-off angles (which indicate whether a window pane is retracted into a vehicle door almost vertically or obliquely) and different adjustment paths including rotations about individual or several vehicle axes (X-, Y and Z-axis), are used and require a specific adaptation of the guide rails or of the guide rails integrated into a base plate or of the guide portions formed on an assembly carrier. For this purpose, individual guide rails or guide rails integrated into an assembly carrier or a base plate, which are formed as guide portions, for example are bent about the longitudinal vehicle axis (X-axis) and/or twisted about the vertical vehicle axis (Z-axis) when they are mounted in a vehicle door.
- It is the object underlying the present invention to provide a motor vehicle window lifter or a door system for a vehicle door with a base plate with guide rails integrated therein, which expands the possibilities of twisting and/or bending at least one guide rail possibly integrated into a base plate or into an assembly carrier and hence the use of guide rails or base plates or assembly carriers with guide rails integrated therein for different vehicle doors and window lifter kinematics.
- In accordance with the invention, this object is solved by the features of
claim 1. - Due to the arrangement of at least one supporting point between the fastening receptacles of the carrier element, on which the guide rail supports when bracing the guide rail with the carrier element, the possibilities of twisting and/or bending a guide rail of a window lifter are expanded and the spectrum of application and use of a window lifter with a twistable or bendable guide rail thereby is increased.
- An essential advantage of determining the pull-off kinematics of a window lifter only during installation of a guide rail or an assembly carrier or a base plate with integrated guide rails into a carrier element or a vehicle door consists in that proceeding from easily and inexpensively manufacturable semifinished products the guide rails or the base plates with integrated guide rails can be adapted to the respective conditions of the vehicle door, namely as regards the required bending radius (pull-off line of the window pane) and/or the required twist of the guide rails. Thus, the invention allows the use of parts according to the invention for use across all model ranges.
- Proceeding from the prior art according to DE 199 42 643 C2, the subject-matter of the present invention not only utilizes the ends or end regions of a straight guide rail as fastening points, which due to the connection with correspondingly aligned fastening receptacles of the carrier bend and/or twist the guide rail in a specifiable manner on bracing with the carrier, but due to the arrangement of at least one supporting point between the fastening receptacles of the carrier a measure is created which has a shaping effect on the curvature and/or twist of the guide rail during bracing of the guide rail with the carrier element. Here and in the following, “carrier element” is understood to be the door body of a vehicle door accommodating a window lifter, in particular a door inner panel, a carrier plate insertable into the door frame of a vehicle door or a function carrier for module doors or door systems. Furthermore, the term “supporting point” also includes a supporting region and hence not only a point- or line-shaped support, but also a planar support.
- The arrangement of at least one further fastening and/or supporting point between the fastening receptacles of the carrier element provides for not only bending or twisting a substantially straight, in particular extruded or roller-burnished, guide rail when bracing the guide rail with the carrier element by supporting the guide rail on the supporting point and attaching the same to the fastening receptacles of the carrier element, but also bend up a guide rail pre-bent with a first bending radius to a second bending radius, which is greater than the first bending radius, by supporting and/or attaching the guide rail to the supporting point and attaching the same to the fastening receptacles of the carrier element, and/or twist the same in a specifiable manner.
- As a result, one and the same guide rail can be used for different vehicles and vehicle types with different window capstans or window curvatures and different strokes by corresponding cutting-to-length of the extruded or roller-burnished guide rail. In addition, the use of the same guide rail for left and right front and rear doors of a vehicle is possible. For manufacturing the guide rail only one extrusion tool is required, whereby investments are saved.
- By pre-bending a guide rail and possibly by arranging at least one further fastening point between the fastening points arranged in the end regions of the guide rail, between which and the further fastening point at least one supporting point each is arranged, complex configurations of the guide rail for example with different radii or twists in the longitudinal extension of the guide rail can also be realized with simple means.
- Alternatively, a pre-bent guide rail can also be straightened by supporting the guide rail on the supporting point and attaching the same to the fastening receptacles of the carrier element, so that the guide rail for example is attached to the supporting point under pretension, in order to establish a non-positive or integral connection of the guide rail with the supporting point by gluing, welding or the like.
- Furthermore, by arranging several supporting points between the fastening points arranged in the end regions of the guide rail several contact points can be provided, which correspond to the exact bend of the guide rail with a bending radius or several bending radii or twists.
- By arranging more than two fastening points, the possibility of creating several connecting points and hence an increased stiffening and stabilization of the guide rail is given.
- On a plastic carrier, different receiving positions for extruded or roller-burnished guide rails are created and by attaching the extruded guide rail to the carrier, the guide rail is brought into a constrained position and assumes a particular, defined curvature and twist.
- The guide rail can be braced both with a carrier plate or a function carrier as carrier element and also directly with the vehicle door, in general with the door inner panel. A further design variant consists in providing at least one fastening receptacle on the vehicle door as carrier element and at least one fastening receptacle on a carrier plate to be connected with the vehicle door or a function carrier as carrier element, wherein the fastening receptacles of the carrier plate or the function carrier and the vehicle door correspond with corresponding fastening points of the guide rail.
- Bracing the guide rail both with a carrier plate or a function carrier and with a vehicle door accommodating the carrier plate or the function carrier as carrier elements provides for pre-bending or pre-twisting the guide rail when bracing the same with the carrier plate or the function carrier, and for bracing the same to the final bending radius or the final twist when inserting and connecting the same with the vehicle door as carrier element.
- In addition, it is possible to pre-position the guide rail by means of a hook-shaped fastening receptacle formed at the carrier element, which can be put through a fastening point of the guide rail formed as opening.
- Alternatively, it hence is possible to provide a first bending radius of the guide rail pre-mounted on the carrier plate and generate a second bending radius when mounting the carrier plate in the door body with the guide rail pre-mounted on the carrier plate.
- In this variant of the solution according to the invention, different bending radii or degrees of twisting thus can be generated and hence an adaptation of the guide rail also to complicated contours or paths of movement on pull-off of the window pane of the window lifter can be realized.
- The type and shape of the fastening points of the guide rail and the fastening receptacle of the carrier element and of the supporting point or supporting points permits a multitude of variants which can be adapted to the respective requirements as to the shape, i.e. bend and/or twist, or bracing of the guide rail with the carrier element or the carrier elements.
- For a preassembly of the guide rail on a carrier plate, a function carrier or assembly carrier as first carrier element and final assembly of the first carrier element connected with the guide rail into a vehicle door as second carrier element a connection is suitable in which a first fastening receptacle of the carrier element is formed as hook or pocket protruding from the carrier element, into which an end of the guide rail can be put, and a second fastening receptacle consists of a clip protruding from the carrier element, which engages behind the guide rail via an opening in the guide rail. The connection of the first carrier element with the guide rail pre-mounted thereon with the vehicle door as second carrier element can be effected in the usual way via a screw connection, wherein for sealing an opening provided in the door body a circumferential seal is provided between the edge of the carrier plate, the function or assembly carrier and the opening edge of the door body.
- Due to this design of the fastening points, fastening receptacles and the supporting point between the first and second fastening receptacle, the guide rail is held in the preassembly position by putting the one end of the guide rail into the pocket of the carrier plate and by the clip connection and is fixed in X-, Y- and Z-direction and pre-bent to a first bending radius, while in the subsequent final assembly for example by connecting the other end of the guide rail with the bodyshell of the vehicle door a further bending radius is generated or a defined radius of the preferably extruded or roller-burnished guide rail is generated after attachment to the door bodyshell.
- Alternatively, the fastening receptacles of the carrier element can consist of a carrier element hook protruding from the surface of the carrier element and a clip, and the fastening points of the guide rail can consist of a guide rail hook, which engages behind the carrier element hook, and a clip protrusion cooperating with the clip of the carrier element, wherein the connecting elements are formed such that after putting the guide rail hook into the carrier element hook the guide rail can be pivoted about the positive connection of the guide rail hook and the carrier element hook, until the clip protrusion of the guide rail snaps into the clip of the carrier element.
- Due to this design of the connecting elements, a simple and functionally reliable connection of a guide rail with a carrier element is ensured on bending or twisting the guide rail, and the basis for an increased stability of the guide rail is given by the arrangement of supporting regions.
- With the arrangement of a cutout in the surface of the carrier element facing the guide rail, a plug-in opening of the carrier element hook is created for receiving an elongated guide rail hook for a larger undercut and hence for an optimum stability.
- Further variants of the connection of a guide rail with a carrier element for twisting and/or bending the guide rail by bracing the fastening points of the guide rail with the fastening receptacles of the carrier element with at least one supporting point between the fastening receptacles of the carrier element are:
-
- forming at least one fastening receptacle of the carrier element and one fastening point of the guide rail and/or at least one supporting point of the carrier element as adhesive connection between the surfaces of the carrier element and the guide rail, preferably with
- at least one spacer arranged between the surfaces of the carrier element to be connected and the guide rail, which protrudes from the surface of the carrier element and/or the guide rail, to ensure a defined thickness of the adhesive layer for an optimum and durable adhesive connection, and/or
- depressions arranged laterally of the surfaces of the carrier element to be connected by the adhesive connection and the guide rail and/or at least one opening in the carrier element arranged in the region of the surfaces of the carrier element to be connected by the adhesive connection and the guide rail, into or through which excess, non-cured adhesive can flow off,
- a structuring of the surface of the carrier element by alternating elevations and depressions, so that between the surface of the guide rail and the elevations and depressions of the surface of the carrier element alternating spaces are formed for receiving adhesive,
- a formation of at least one fastening receptacle of the carrier element as clip connection, into which the lateral edges of the guide rail can be clipped,
- manufacturing the guide rail of an extruded plastic material permeable for laser radiation and the carrier element of a material absorbing laser radiation, or vice versa a guide rail of a material absorbing laser radiation and a carrier element of a plastic material permeable for laser radiation, wherein the guide rail is pre-bent and fixing elements protrude from the surface of the carrier element, which engage behind the edges of the pre-bent guide rail such that a part of the surface of the guide rail is brought in contact with a part of the surface of the carrier element, so that the adjacent surface portions of the guide rail and the carrier element are connectable with each other by laser welding,
- a formation of the at least one fastening point of the guide rail as clip, which can be clipped into a fastening receptacle of the carrier element formed as opening in the carrier element,
- forming a hook- or pocket-shaped stop on the surface of the carrier element for receiving a guide rail end and a mounting aid protruding from the surface of the carrier element for aligning the guide rail put into the hook- or pocket-shaped stop on the surface of the carrier element,
- a rectangular or trapezoidal depression with legs of the carrier element horizontally angled from the edge of the depression, to which a rectangular or trapezoidal depression of the guide rail is adapted, which with its side legs horizontally angled from the edge of the depression rests on the legs of the carrier element angled from the rectangular or trapezoidal depression, wherein the rigidity of the connection of the guide rail with the carrier element is increased by the sandwich construction,
- fastening receptacles of the carrier element and fastening points of the guide rail from mutually spaced rivet or screw connections or alternatively adhesive connections between the adjacent surfaces of the guide rail and the carrier element,
- structuring the bottom of the box-shaped profile of the carrier element, in order to create cavities which effect a high moment of resistance and hence a high mechanical stability,
- forming the guide rail as extruded plastic rail with an extruded fleece, fabric, paper, film inserted in a sandwich construction or with a metallic or non-metallic insert for improving the rigidity.
- forming at least one fastening receptacle of the carrier element and one fastening point of the guide rail and/or at least one supporting point of the carrier element as adhesive connection between the surfaces of the carrier element and the guide rail, preferably with
- When connecting the guide rail with the carrier element, the following material combinations preferably are used:
-
- plastic guide rail with a plastic carrier element
- metallic guide rail with a metallic carrier element
- metallic guide rail with a plastic carrier element
- plastic guide rail with metallic carrier element
- As metallic materials steel, aluminum and magnesium preferably are used. A plastic guide rail or a plastic carrier element preferably consists of a thermoplastic and/or thermoset material, which are used with and without reinforcing materials or fillers, such as for example a glass-fiber reinforced thermoplastic material. Manufacturing a plastic guide rail is effected by extrusion, injection molding, deep drawing, blow molding or pressing, manufacturing a plastic carrier element is effected by injection molding, deep drawing, blow molding and pressing, manufacturing a metallic guide rail is effected by roller burnishing, press forming or extruding, and manufacturing a metallic carrier element is effected by press forming or die casting.
- For increasing the stability, a cassette which accommodates a cable pulley holder or a cable pulley of a cable window lifter deflecting a window lifter cable, can be integrated into the connection of the guide rail with the carrier element, for example a door inner panel or a carrier plate or a function carrier. For this purpose, the cassette preferably includes two bearing surfaces forming a rear grip of the cassette on the guide rail, via which the cassette is connected with the guide rail, and by a cutout in the guide rail is connected with the cable pulley, a stepped pin with internal thread, on which the cable pulley is mounted, and with the carrier element, in that a screw put through an opening of the carrier element is screwed to the internal thread of the stepped pin.
- The cassette either is supported on the carrier element and hence loaded via the bearing surfaces, or the bearing surfaces are spaced from the carrier element, while the bottom of the stepped pin with internal thread rests against the carrier element and thereby relieves the cassette.
- As an alternative to the use of individual guide rails and their connection with a carrier element, there can also be used a door module or door system for a vehicle door with an assembly carrier or a window lifter base plate with at least one bendable and/or twistable guide rail integrated into the assembly carrier or the base plate for guiding a driver to be coupled with a window pane along an adjustment direction. By connecting the guide rail with a rigid region of the base plate or the assembly carrier via connecting portions, which include at least one flexible region, a twisting and/or bending of the guide rail is effected when connecting fastening points of the assembly carrier or the base plate with fastening receptacles of a vehicle door, in particular with the door bodyshell of the vehicle door.
- This expansion of the solution according to the invention for individual guide rails of a window lifter to base plates (or assembly carriers) with at least one guide rail integrated into the base plate thus also provides for twisting or bending the guide rail when mounting the base plate in the door bodyshell of a vehicle door and hence for using a base plate for different vehicles and vehicle types of different vehicle manufacturers as well as for a compensation of tolerances when mounting the base plate in the door bodyshell of the vehicle door or a compensation of manufacturing inaccuracies.
- Preferably, the base plate and the guide rail are made such that the guide rail is bendable about the longitudinal vehicle axis (X-axis) and twistable about the vertical vehicle axis (Z-axis).
- Due to this deformability of a base plate or a guide rail, there are also realized complicated adjustment paths or adjustment directions during pull-off of a window pane, in particular during pull-off of barrel-shaped window panes. When using two guide rails arranged at the lateral edges of a base plate, the rigid region of the base plate preferably is arranged between the guide rails, while the fastening points are provided at the ends of the guide rails and at least one supporting or further fastening point is provided between the end-side fastening points of the guide rails.
- This first embodiment of a flexible base plate provides for a relatively stiff design of the guide rails without impairing the possibility of bending and/or twisting the guide rails for realizing different pull-off kinematics when connecting the base plate with the door bodyshell of a vehicle door.
- In a second embodiment, the base plate alternatively includes two guide rails whose middle regions are connected with each other via a rigid cross-beam at whose ends fastening points are arranged, which are connected with the door bodyshell of a vehicle door, so that the ends of the guide rails are without connection to the rigid cross-beam and a flexibility of the guide rail legs hence is obtained.
- Preferably, the fastening points are at least partly arranged on the axles of deflection pulleys of the window lifter for guiding and deflecting a window lifter cable.
- By integrating fastening points into the axles of deflection pulleys of the window lifter, the possibilities of mounting a base plate into the door bodyshell of a vehicle door are expanded, in that for example an opening in the door inner panel of a vehicle door is covered, which has such a size that the connection of the base plate with the door bodyshell only is possible at the outer ends.
- For optimization and simplification of the mounting of a base plate into the door bodyshell of a vehicle door, components integrated into the door bodyshell of the vehicle door such as crash barriers can also be used as supporting points.
- In a preferred embodiment, the connecting portions of the base plate are formed as struts which are connected with the ends and a middle portion of the guide rails.
- The formation of the connecting portions as struts, in particular as diagonal and transverse struts, instead of a full-surface formation of the connection of the rigid middle region of the base plate with the guide rails on the one hand creates a saving of material and on the other hand the prerequisite for a selective arrangement of flexible regions in the struts, in order to achieve a defined flexibility for bending and/or twisting the guide rails.
- The flexibility required for bending and/or twisting the guide rails can be achieved in that the diagonal struts connected with the ends of the guide rails or the transverse struts connected with the middle portions of the guide rail contain the flexible regions.
- While the arrangement of the flexible regions in the diagonal struts ensures a high flexibility in the end regions of the guide rails, the arrangement of flexible regions in the transverse struts provides for a high flexibility of the guide rail in the middle region with a relatively rigid formation of the end regions of the guide rails.
- The flexible regions can be manufactured in different ways, namely
- a) by reducing the cross-section of the flexible region as compared to the cross-section of a rigid region of the connecting portions or struts, i.e. by thinning out the material in the flexible region,
- b) by a flat design of the flexible regions or by use of one of the connecting portions or struts,
- c) by a combination of the two variants a) and b), in that the flexibility is accomplished by thinning out the material and by a flat design of the flexible regions or by use of cross-sections with low moments of resistance,
- d) by using the 2-component technique, in which the rigid region is made of a rigid material, in particular of a long glass fiber-reinforced plastic material, and the flexible region is made of a flexible material, in particular a thermoplastic elastomer (TPE) or a material with lower modulus of elasticity, in particular of non-reinforced polypropylene,
- e) by a combination of the variants b) and d), in that rigid regions, of a cross-sectional shape with a high moment of resistance are combined with a rigid material, and flexible regions with a cross-sectional shape with a lower moment of resistance than the cross-sectional shape of the rigid region are combined with a flexible material,
- f) by a combination of the variants a), b) and d), i.e. by the combination of a reduction in cross-section with a flat design and use of a flexible material for the flexible regions and by the combination of an enlarged cross-section with a high moment of resistance and use of a rigid material for the rigid regions,
- g) establishing the flexibility by the spring action of a wave-like structure of the connecting portions or struts, wherein the wave-like structure can be provided
- in longitudinal direction of the connecting portions,
- in direction of the vertical vehicle axis (Z-axis),
- in direction of the longitudinal vehicle axis (X-axis), or
- in several regions both in direction of the vertical vehicle axis (Z-axis) and in direction of the longitudinal vehicle axis (X-axis).
- To further increase the possibilities of using the design of a base plate according to the invention with integrated guide rails for different vehicles and vehicle types of different vehicle manufacturers, the base plate is formed as mounting frame with connecting portions on whose end regions articulations are arranged for accommodating guide rails for different window lifters, window lifter types and/or vehicle doors, wherein the mounting frame preferably is formed X-shaped with a rigid, middle region and four diagonal struts each extending diagonally from the rigid middle region, whose ends are angled and include variable articulations for accommodating different guide rails.

FIG. 1 shows a schematic longitudinal section through astraight guide rail 3 preferably extruded from a plastic material or roller-burnished from a metallic material and a longitudinal section through acarrier element 2 with twofastening receptacles 41 associated to the end regions of theguide rail 3 and a supportingpoint 61 arranged in the center of or off-center from thefastening receptacles 41. By placing theguide rail 3 on thefastening receptacles 41 and the supportingpoint 61 in direction of arrow and by connecting the end regions of theguide rail 3 at the fastening points 51 of theguide rail 3 with thefastening receptacles 41 of thecarrier element 2, theguide rail 3 as shown inFIG. 2 is bent with a bending radius R. What is not shown is a possible additional twisting of theguide rail 3 by an arrangement of thefastening receptacles 41 and the supportingpoint 61 not in alignment with each other, so that the same include an angle in longitudinal direction which determines the measure of the twisting of theguide rail 3 in longitudinal direction. -
FIG. 3 shows a schematic longitudinal section through the door bodyshell of avehicle door 1 with a doorouter panel 1 a and a doorinner panel 1 b withcarrier element 2 inserted into thevehicle door 1 and braced with theguide rail 3 in the preassembly position as shown inFIG. 2 , which is connected with the doorinner panel 1 b of thevehicle door 1 in a manner known per se, wherein aseal 1 c extending around the edge of thecarrier element 2 seals an opening in the doorinner panel 1 b. Since only thecarrier element 2 with theguide rail 3 pre-mounted thereon is attached to the doorinner panel 1 b of thevehicle door 1, the bending radius R of theguide rail 3, which was generated on bracing theguide rail 3 with thecarrier element 2 during preassembly, is maintained. - Due to the arrangement of the supporting
point 61 between thefastening receptacles 41 of thecarrier element 2, not only the end regions of theguide rail 3 are used for bracing the guide rail for generating a bend and/or twist of theguide rail 3, but also the supportingpoint 61 is utilized, which has a shaping effect on the curvature and/or twist of theguide rail 3. - To illustrate the mounting position of the
carrier element 2 with the guide rail pre-mounted thereon, a system of coordinates with the longitudinal vehicle axis X, the transverse vehicle axis Y and the vertical vehicle axis Z is indicated inFIG. 3 , which illustrates the orientation of thecarrier element 2 and theguide rail 3 in thevehicle door 1. - The significance of the supporting
point 61 is made particularly clear below with the exemplary embodiment shown inFIGS. 4 to 6 , which relates to apre-bent guide rail 3′ which is connected with acarrier element 2 which includes twofastening receptacles 41 associated to the end regions of thepre-bent guide rail 3′ and afastening receptacle 42 located in between. By applying thepre-bent guide rail 3′ in direction of the arrows shown inFIG. 4 to thecarrier element 2 and subsequently connecting the fastening points 51, 52 of thepre-bent guide rail 3′ with thefastening receptacles carrier element 2, theguide rail 3′ previously pre-bent to a bending radius R1 is bent to a bending radius R2 different from the bending radius R1 and is braced with thecarrier element 2 in this preassembly position. -
FIG. 6 shows a schematic longitudinal section through the door bodyshell of thevehicle door 1 with the doorouter panel 1 a and the doorinner panel 1 b with thecarrier element 2 inserted into thevehicle door 1 and in the preassembly position as shown inFIG. 5 braced with theguide rail 3 and connected with the doorinner panel 1 b of thevehicle door 1. Since only thecarrier element 2 is attached to the doorinner panel 1 b of thevehicle door 1, the bending radius R2 of theguide rail 3′, which was generated on bracing theguide rail 3′ with thecarrier element 2 during preassembly, is maintained. - In
FIGS. 7 to 9 further variants of the solution according to the invention are shown in schematic longitudinal sections through acarrier element 2 withpre-mounted guide rail 3, which can be derived from the two exemplary embodiments described above. -
FIG. 7 shows a variant with acarrier element 2 which includes two end-side fastening receptacles 41 associated to the end regions of theguide rail 3 and amiddle fastening receptacle 42 arranged between the end-side fastening receptacles 41. Between the end-side fastening receptacle 41 and the middle fastening receptacle 42 a supportingpoint 62 each is provided, which in conjunction with thefastening receptacles guide rail 3 after connecting the fastening points 51, 52 of theguide rail 3 with thefastening receptacles the'carrier element 2. - In
FIG. 8 an embodiment is shown in a schematic longitudinal section, in which thecarrier element 2 includes several, in the illustrated exemplary embodiment three supportingpoints fastening receptacles 41 associated to the end regions of the guide rail. When connecting the end-side fastening points 51 of theguide rail 3 with thefastening receptacles 41 of thecarrier element 2, theguide rail 3 rests against the supportingpoints guide rail 3 on bracing theguide rail 3 with thecarrier element 2. -
FIG. 9 shows a schematic longitudinal section through an expansion of the exemplary embodiment as shown inFIGS. 4 to 6 , wherein in the embodiment ofFIG. 9 beside thefastening receptacles 41 associated to the end regions of theguide rail 3 and amiddle fastening receptacle 42, which are connected with the fastening points 51, 52 of theguide rail 3, twofurther fastening receptacles 43 are arranged between the end-side fastening receptacles 41 and themiddle fastening receptacle 42, which are connected withfastening points 53 of theguide rail 3. In this embodiment, thefastening receptacles guide rail 3, in particular apre-bent guide rail 3. - In
FIGS. 10 and 11 two exemplary embodiments are shown in a schematic longitudinal section, in which theguide rail 3 pre-mounted on a carrier plate, a function carrier orassembly carrier 2 and pre-bent with a first bending radius R1 is connected with thevehicle door 1 as second carrier element after inserting the carrier plate, the function orassembly carrier 2 into avehicle door 1 at anupper fastening point 56, in order to generate a second bending radius R2 or an additional twist. - In a schematic longitudinal section through a
vehicle door 1,FIG. 10 shows a preassembly group consisting of a carrier plate or a function orassembly carrier 2 as first carrier element with an extrudedguide rail 3 pre-mounted on thecarrier plate 2, wherein the preassembly position of theguide rail 3 is shown in broken lines. In this preassembly position, theguide rail 3 is connected with thecarrier plate 2 via twofastening points carrier plate 2, which is put through afirst fastening point 54 of theguide rail 3 formed as opening, in order to fix theguide rail 3 in the preassembly position. - A
second fastening receptacle 45 of thecarrier plate 2 is formed as hook or pocket, into which the lower end of theguide rail 3, which forms alower fastening point 55, is put in the preassembly position. Thefastening receptacle 45 formed as hook or pocket determines the positioning of theguide rail 3 in Y- and Z-direction of the motor vehicle. - Through a supporting
point 61 arranged between thefastening receptacles 44, 45 on the carrier plate 2 a contact point for theguide rail 3 is specified, by which in conjunction with the arrangement and design of the fastening receptacles 44, 45 a first bending radius R1 of theguide rail 3 is determined in the preassembly position. - After attaching or inserting the preassembly group into an opening of the door bodyshell of the
vehicle door 1 provided in the doorinner panel 1 b of thevehicle door 1, the upper end of theguide rail 3 with thefastening point 56 is connected with the sill region of the doorinner panel 1 b asfastening receptacle 41 for example by means of a screw connection, whereby theguide rail 3 obtains a second bending radius R2 which can correspond with the first bending radius R1 or differ from the same. Theguide rail 3 thereby obtains a specified pull-off line when lifting and lowering the driver longitudinally movable along theguide rail 3, which accommodates a window pane for opening and closing a door opening along theguide rail 3. - While the arrangement of the clip 44 on the
carrier plate 2 determines the orientation of theguide rail 3 in X-direction, the length of the clip 44 or the height of the supportingpoint 61 determines the bending radius R1 of theguide rail 3 in the preassembly position. When arranging a clip 44 offset in X-direction of the motor vehicle with respect to the hook or thepocket 45, theguide rail 3 thus is inclined in the one or other direction in X-direction. - In a longitudinal section,
FIG. 11 shows a preassembly group consisting of acarrier plate 2, in particular a function or assembly carrier, which is inserted into avehicle door 1, comprising aguide rail 3 braced with thecarrier plate 2 corresponding to the embodiment as shown inFIGS. 1 to 3 . In the preassembly position, theguide rail 3 is bent to a bending radius R1 by connecting the fastening points 51 to thefastening receptacles 41 of thecarrier plate 2 and by supporting on the supportingpoint 61 arranged between thefastening receptacles 41 at thecarrier plate 2.

Above and below theadhesive surface 70spacers 24 are arranged, which when clipping theguide rail 3 onto thecarrier element 2 ensure a sufficient distance between the bottom surface of theguide rail 3 and the upper surface of thecarrier element 2, in which the adhesive is effective. To increase the stability of thecarrier element 2 and for an optimum absorption of adhesive, thecarrier element 2 has a structuredsurface 29 between thespacers 24, at whose endschambers 23 are provided, into which excess adhesive can flow off. - In a top view of the

FIG. 30 shows a top view of the connection of aguide rail 3 with acarrier element 2, which inFIGS. 31 and 32 is shown in two different embodiments in a section along line DD ofFIG. 30 . - In the two embodiments shown in
FIGS. 31 and 32 , analogous to the embodiment ofFIG. 26 , thecarrier element 2 includes a rectangular ortrapezoidal depression 25 withlegs 28 horizontally angled from the edge of the depression, to which a rectangular ortrapezoidal depression 34 of theguide rail 3 is adapted, which with itsside legs 35 horizontally angled from the edge of the depression rests on thelegs 28 of thecarrier element 2 angled from the rectangular ortrapezoidal depression 25.

In the screw connection, a dome-like protuberance 200 protrudes from the bottom of the rectangular ortrapezoidal depression 25 of thecarrier element 2 for providing a sufficient length for the thread of thescrew 79. - Since the beveled edges of the
carrier element 2 and of theguide rail 3 engage in each other, a closed section with a high moment of resistance and hence a high mechanical stability also is created in these embodiments to improve the rigidity of theguide rail 3. Thecarrier element 2 for example is a steel or aluminum function carrier, while theguide rail 3 is formed as extruded plastic rail or roller-burnished steel or aluminum rail. - The embodiment shown in

By laser welding by means of a laser beam LS, as shown inFIG. 35 , theguide rail 3 is attached to thecarrier element 2 between thebase surface 300 of theguide rail 3 and the stepped, dome-shapedelevation 27 of thecarrier element 2. - In this embodiment, the
guide rail 3 is formed as extruded plastic rail with a material permeable or transmissive for laser radiation. Thecarrier element 2 preferably also is made of plastic material with a material absorbing the laser radiation. - The inventive solution of twisting or bending a guide rail for increasing the stability and creating a specifiable pull-off of a window pane can also be realized by including further elements of a window lifter, wherein these elements only can serve for twisting or bending the guide rail, only for increasing the stability and rigidity of the guide rail and/or of the carrier element or both for twisting or bending the guide rail and for increasing the stability and rigidity.

Thecassette 15 supports on thecarrier element 2 via the two bearingsurfaces carrier element 2 by means of ascrew 19 put through anopening 20 of thecarrier element 2, which is screwed to the internal thread of the steppedpin - In the embodiment of
FIG. 36 thebottom 160 of the stepped pin withinternal thread 16 is spaced from thecarrier element 2, whereas the exemplary embodiments represented inFIGS. 37 and 38 show screw-through solutions for an increase in stability, wherein in the embodiment ofFIG. 37 thebottom 170 of the stepped pin withinternal thread 17 and thecassette 15 support on thecarrier element 2 via the two bearingsurfaces cassette 15 is loaded, whereas in the exemplary embodiment shown inFIG. 38 a relief of thecassette 15 is effected in that the same is merely put onto theguide rail 3, but does not support on thecarrier element 2 itself via the bearing surfaces 151, 152. - In the embodiment as shown in
FIG. 38 the connection of thecable pulley 14, thecassette 15 and theguide rail 3 with thecarrier element 2 is effected via a steppedpin 18 whosebottom 180 rests against thecarrier element 2 and is attached to thecarrier element 2 with ascrew 19 put through anopening 20 of thecarrier element 2, which is screwed to the internal thread of the steppedpin 18. - The above-described mounting of guide rails of a window lifter into the door bodyshell of a vehicle door for manufacturing a bent and/or twisted guide rail during the connection of fastening points of the guide rail with fastening receptacles on a carrier element, for example the door bodyshell of a vehicle door, an assembly carrier or a window lifter base plate, and supporting points for manufacturing a desired pull-off kinematics, also is applicable to assembly carriers or base plates with integrated guide rails. The various applications and possibilities of use will be explained below with reference to
FIGS. 39 to 70 . - In relation to a coordinate system with the longitudinal vehicle axis or x-axis, the trans-verse vehicle axis or y-axis extending vertically to the drawing plane and the vertical vehicle axis or z-axis,
FIG. 39 shows abase plate 8 for a window lifter with the components of a double-stranded window lifter arranged thereon, namely adrive unit 10 with a cable drum for driving awindow lifter cable 12, which is guided via cable or deflection pulleys 131, 132, 133, 134 and is connected with twodrivers 11 arranged and guided onguide rails drivers 11 coupled with a window pane are lifted or lowered on theguide rails drive unit 10, whereby the window pane opens or closes a window opening of a door frame. - The
flexible guide rails base plate 8. For this purpose, thebase plate 8 has amiddle region 80 connected to the center of the oneguide rail 3 a, which is made of a rigid material and/or has a cross-section or a cross-sectional shape with a high moment of resistance. From therigid region 80 connectingportions guide rails transverse strut 85 leads to the center of theother guide rail 3 b. At the upper and lower ends of theguide rails window lifter cable 12 are arranged, whose axles also can serve asfastening points 5 for connecting thebase plate 8 with the door bodyshell, in that fastening bolts are put through the axles of the cable or deflection pulleys 131, 132, 133, 134 and are connected with the door bodyshell of a vehicle door. - Alternatively,
separate fastening points 5′ can be provided in the connection for example between the upper ends of theflexible guide rails diagonal struts FIG. 39 , through which fastening bolts are put and connected with the door bodyshell. - On both sides of the
rigid region 80 of thebase plate 8, two supportingpoints 6 are provided on theflexible guide rails base plate 8 with the door bodyshell of a motor vehicle door. Therigid region 80 of thebase plate 8 thus is located between the supportingpoints 6 and for example serves for bearing thewindow lifter drive 10. - Depending on the vehicles of different vehicle manufacturers, on the vehicle types and the formation of a vehicle door, the adjustable window pane of a window lifter can be formed differently. In dependence on the shape of a vehicle door, a window pane for example can have a certain radius of curvature, which can be different in different vehicle doors and specifies a path of movement along which the window pane is moved into the door body formed of the door outer panel and the door inner panel or is moved out of, the same for adjustment. In addition, the path of movement of the window panes can be formed differently and for example be moved into the door body or out of the same almost vertically or obliquely, or for avoiding obstacles in the door body or for the flush abutment of a bent, barrel-shaped window pane on the door seal be swiveled about the longitudinal vehicle axis (X-axis), transverse vehicle axis (Y-axis) or vertical vehicle axis (Z-axis) or be pivoted in planes formed by the three axes, so that as a result of these specifications the guide rails determining the path of movement of the window panes must be bent or twisted correspondingly in their longitudinal extension.

FIGS. 40 and 41 show a schematic view of avehicle door 1 in whose door bodyshell abase plate 8 as shown inFIG. 39 is incorporated for realizing various pull-off angles α of awindow pane 13 of a window lifter. Depending on the required pull-off angle α of the window pane, thebase plate 8 is rotated into the respectively correct position, i.e. with an oblique pull-off of the window pane thebase plate 8 as shown inFIG. 40 is mounted with an inclination at a pull-off angle α with respect to the vertical vehicle axis or z-axis, whereas with a vertical pull-off of thewindow pane 13 thebase plate 8 as shown inFIG. 41 is connected with the door bodyshell of the vehicle door with a vertical alignment of theguide rails -
FIG. 42 shows a schematic view of thebase plate 8 ofFIG. 39 withguide rails base plate 8 in relation to a coordinate system, reference being made to the above description ofFIG. 39 with respect to the reference numerals used. - For bending or twisting the
guide rails base plate 8 into the door bodyshell of a vehicle door, thediagonal struts 81 to 84 includeflexible regions 9. While therigid region 80 of thebase plate 8 in the middle region of thebase plate 8 on the one hand is directly connected with the oneguide rail 3 a, the connection with theother guide rail 3 b is effected via the rigiddiagonal strut 85, which is connected with the middle region of theguide rail 3 b. - In an alternative embodiment,
FIG. 43 shows abase plate 8 withintegrated guide rails FIG. 42 , but with an arrangement of flexible regions ontransverse struts guide rails -
FIG. 44 shows a schematic longitudinal section through one or both guide rails 3 (3 a, 3 b as shown inFIGS. 42 and 43 ) integrated into thebase plate 8 in the unbraced condition before mounting into a vehicle door in relation to a system of coordinates, with theguide rail 3 being pre-bent with a radius R. When mounting thebase plate 8 into a vehicle door and connecting the fastening points 5 with the door bodyshell with the supportingpoints 6 resting on corresponding add-on parts of the vehicle door, theguide rail 3 is brought into a constrained position, which results in the desired rail radius. -
FIG. 45 shows theguide rail 3 after connecting the fastening points 5 with thefastening receptacles 4 of the door bodyshell and supporting theguide rail 3 on the supportingpoint 6, so that thepre-bent guide rail 3 is “bent up” to a radius RA, with RA>R. - Alternatively, when mounting the
base plate 8 into a vehicle door and attaching the fastening points 5 tocorresponding fastening receptacles 4 of the door bodyshell and supporting theguide rail 3 on a supportingpoint 6, theguide rail 3 ofFIG. 46 can be “bent further” to a radius RB, i.e. RB<R. - These two schematic representations of
FIGS. 45 and 46 clearly show that one and the same pre-bent,flexible guide rail 3 integrated into thebase plate 8 withflexible regions 9 assumes different configurations when mounted in different vehicle doors, when thebase plate 8 is connected with the door bodyshell of a vehicle door, so that thebase plate 8 with theintegrated guide rails 3 is suitable for different pull-off kinematics and configurations of window lifters. - The variant schematically illustrated in
FIG. 47 of abase plate 8′ with integratedflexible guide rails FIG. 42 or 43, but establishes the flexibility for twisting theguide rails rigid cross-beam 88 is provided between theguide rails base plate 8 is obtained, which provides for twisting theguide rails base plate 8 to the door bodyshell of a vehicle door, further fastening points such as, the connection via the axles of the deflection pulleys 131-134 or additionally arrangedfastening points 5′ can be provided. - With reference to a side view of a
vehicle door 1 as shown inFIG. 48 with abase plate 8 withintegrated guide rails FIGS. 49 and 50 through thevehicle door 1 ofFIG. 48 along the sectional line A-A, the possibility of a multi-point support for internal and external window lifters will be explained in detail. -
FIG. 48 shows avehicle door 1 with a substantiallyrectangular opening 1 d provided in the door bodyshell, into which twolateral projections base plate 8 mounted into the door bodyshell for an oblique pull-off of the window pane at a pull-off angle with respect to the vertical vehicle axis is connected with the door bodyshell viafastening points 5 which are put through the axles of the deflection pulleys of the window lifter. For establishing a specified bend or twist of theguide rails base plate 8, supportingpoints 6 are provided in the region of theprojections guide rails base plate 8. - In an internal window lifter system shown in
FIG. 49 in a longitudinal section, thebase plate 8 is connected with the doorinner panel 1 b of the door body by fastening means put through the deflection pulleys and is supported on the supportingpoints 6 provided at theprojections window pane 13 is adjusted along a specified pull-off path. - In an external window lifter system shown in
FIG. 50 in a longitudinal section through the vehicle door, thebase plate 8 is attached to parts of the door bodyshell provided adjacent to the doorouter skin 1 a and for example can support on aside impact carrier 1 g. - As an alternative to the support of the
base plate 8 on supports of theprojections FIG. 50 can be used in an internal window lifter system for supporting thebase plate 8, which in particular is connected with the door inner panel. - With reference to
FIGS. 51 to 53 it will be described how a guide rail is broUght into a constrained position by connection with the door bodyshell of a vehicle door and thereby is twisted or tilted. -
FIG. 51 shows a top view and a side view with a system of coordinates for illustrating the mounting position of abase plate 8 with aguide rail 3 a integrated into thebase plate 8, the so-called A-rail, and aguide rail 3 b integrated into thebase plate 8, the so-called B-rail, in a starting situation. By arranging aflexible region 9 in thebase plate 8, for example by a corresponding design of therigid region 80 of thebase plate 8 and diagonal struts extending from therigid region 80 to the upper and lower ends and to the middle region of the B-rail 3 b with flexible regions provided in the diagonal struts, the B-rail 3 b can be bent and/or twisted, whereas the A-rail 3 a is connected with the door bodyshell in its form present in the starting situation. - The side view of
FIG. 51 illustrates that in the starting situation bothguide rails - After connecting the A-rail 3 a with the door bodyshell at the fastening points 5 at the upper and lower deflection pulleys of the A-rail 3 a, a force is applied onto the ends of the B-rail in direction of the depicted arrows F and the B-rail for example is connected with the door bodyshell by means of screw bolts put through the axles of the deflection pulleys serving as
fastening points 5 at the upper and lower ends of the B-rail 3 b and hence brought into a constrained position, in which it is rotated or tilted relative to the A-rail 3 a, as is illustrated in the side view ofFIG. 52 . -
FIG. 53 shows that the flexible B-rail 3 b is rotated or tilted in opposite direction by a reversal of the forces F acting onto the ends of the B-rail 3 b, as is illustrated by the side view ofFIG. 53 . - In an analogous application of a pre-bent guide rail, the constrained position of the B-rail as shown for example in
FIG. 52 can exist as starting position after connecting the fastening points 5 at the door bodyshell of a vehicle door, in order to further bend up or bend back the B-rail 3 b after connecting the A-rail 3 a with the door bodyshell when connecting the fastening points 5 of the B-rail 3 b with the door bodyshell, so that the B-rail 3 b is rotated or tilted more or less relative to the A-rail 3 a. - With reference to
FIGS. 54 to 56 various possibilities for achieving the flexibility in the base plate of a window lifter system necessary for twisting or bending a guide rail will be set forth and explained. - As described above, the flexible regions provided in the base plate serve to permit or provide for a bending and/or twisting of the guide rails integrated into the base plate and/or a torsion of the guide rails relative to each other. To explain these possibilities, reference is made to a base plate with flexible regions in diagonal struts of the base plate according to
FIG. 42 with associated description. The possibilities described below for establishing the required flexibility are of course also applicable to an arrangement of the flexible regions in the transverse struts above and below the rigid region of the base plate. - The schematic views of a
base plate 8 withintegrated guide rails flexible regions 9 as well asrigid regions 80 as shown inFIGS. 54 and 56 correspond to the representation ofFIG. 42 and merely serve the identification of the sectional lines for explaining the subsequently described variants for forming flexible regions on thebase plate 8. - The longitudinal section shown in
FIG. 55 through the connectingstrut 81 along the sectional line A-A ofFIG. 54 schematically shows the production of the required flexibility by thinning out the material of the connecting ordiagonal strut 81 as compared to the rigid regions of thediagonal strut 81, so that when using the same material aflexible region 9 is created by a lower moment of resistance. - In a section along sectional line B-B of
FIG. 56 ,FIG. 57 shows the possibility of producing aflexible region 9 in thediagonal strut 81 by a planar or flat design of theflexible region 9 or by using a cross-section with a low moment of resistance. Another possibility for example consists in providing a U-section with closely spaced legs of the U-section in the flexible region, whereas the remaining rigid region of thediagonal strut 81 is formed of a U-section with legs spaced at a greater distance from each other and hence with a higher moment of resistance. - Another possibility for producing flexible regions or portions in a
