Driver for a window regulator

Description

The invention relates to a driver for a window regulator assembly, a method for mounting the driver, a first and a second component of the driver and a tool for mounting the driver.

Window lift assemblies are used in motor vehicles to open and close window panes in the motor vehicle doors. Such known window lifter arrangements have a drive and a guide device for driving and guiding the windows belonging to the window lifter arrangement. Slice on. In this case, the drive device is realized, for example, as a cable pull mechanism, which guides the window pane (manually or electrically actuated), for example inside rails which are accommodated in the A, B or C pillar.

To implement a movement of the cables on a lifting or a lowering movement of the window, a driver, which is also referred to as a lifter, used. On the driver on the one hand, the cable and on the other hand, the window pane are fixed, so that upon actuation of the drive mechanism, the window pane is carried over the driver.

DE 10 2004 017 645 A1 relates to a power window arrangement, in particular for a side letter of a motor vehicle, with a traction device and a driver for a window pane which can be moved up and down by this traction device, wherein the driver has a first attachment point for an upward-pulling end of the window Pulling device and a mounted window pane to this first attachment point in the window pane plane horizontally offset second attachment point for a pulling down end of the pulling device, wherein the window lift assembly further comprises means for positioning and fixing the driver at least three degrees of freedom, so that the driver even when not mounted Window can be kept in a defined position with respect to these degrees of freedom.

US 2002/0050100 A1 shows a window regulator arrangement with a guided by a rail driver, which consists of two components. The first component has a receiving slot for a window pane and further has means for fixing the second component of the driver. The first component further has means for receiving positioning means and can be installed together with the window in the motor vehicle door. The second component is provided for fixing the driver to the rail and has means for temporarily attaching the second component to a motor vehicle door, in particular at a location along the rail, in a second position. The second Component also has means for receiving attached to the first component positioning means and means for fixing the second component to the first component.

DE 10 2005 061 009, unpublished at the time of filing, describes a window regulator assembly and a method for assembling the window regulator assembly. The power window assembly includes a window glass driver, a door inner panel, and positioning means for positioning the driver relative to the door inner panel in a mounting position for mounting the windowpane. The positioning means may occupy a first and a second position, wherein the positioning means in the first position define the mounting position and wherein the positioning means in the second position release a movement of the driver for opening and closing the mounted disc. For mounting the window pane, the driver is held by the positioning means in the mounting position. The window pane is inserted separately in the door. The window pane has a hole, by means of which the window pane can latch with a receptacle of the driver. A disadvantage of the window regulator arrangement specified in the above-mentioned document is that the positioning means are used only for the assembly of the window pane. After assembly, the positioning means fulfill no further function.

The invention is therefore based on the object to provide an improved driver for a window regulator assembly and an improved method for mounting the driver.

The objects underlying the invention are each achieved with the features of the independent claims. Embodiments of the invention are indicated in the dependent claims.

According to the invention, a driver for a window regulator assembly of a motor vehicle door is provided. The driver has a first component. The first component is provided for fixing to a window pane and the first component can be introduced with the window pane into a first position in the motor vehicle door. The driver also has a second component. The second component is releasably attachable to the motor vehicle door in a second position. The second component is movable from the second position to the first position, wherein the first component is connectable to the second component in the first position.

The first component is provided according to the invention for fixing to the window and the first component can be installed together with the window in the vehicle door. The window pane is installed together with the first component so that the first component is in a first position in the motor vehicle door. The second component of the driver can be releasably attached in a second position on the vehicle door. After then the first component is brought into the first position, the attachment of the second component is released on the vehicle door and the second component is moved from the second position to the first position. The first component is connected to the second component in the first position. The driver according to the invention has the advantage that it can be assembled in situ, that is in the vehicle door, from its first and its second components. A positioning means, as indicated in the prior art, is no longer needed. This simplifies installation and reduces installation costs by eliminating the cost of the positioning means. A further advantage of the driver according to the invention is that it can be disassembled relatively easily in the event of a necessary change of the disk. The disc can then be removed together with the first component from the Krafftfahrzeugtür and replaced by a new disc.

According to one embodiment of the invention, the second component has receptacles for a tool, wherein the second component is movable from the second position to the first position using the tool. The factory Consequently, the tool serves to move the second component from the second position to the first position.

According to one embodiment of the invention, the second component of the driver has at least one receptacle for at least one cable of the window regulator arrangement. The second component thus serves to fix at least one cable of the window regulator assembly. As a rule, two cables or the two cable ends of a peripheral cable of the window regulator assembly are fixed to the second component in order to lower or lift the window in the door.

According to one embodiment of the invention, the motor vehicle door has a door module, wherein the second component is mounted in the second position on the door module. The door module further includes a recess over which the second component is accessible from the door side opposite the first and second positions and into which a tool can engage from the opposite side of the door to move the second component from the second position to move the first position. The door module can be wholly or partly made of plastic or sheet metal.

According to one embodiment of the invention, the second component comprises means for positioning the first component in the first position. The second component is releasably secured in the second position. By the means for positioning the first component, which are detachably attached to the second component, thus the first position is defined. The first component, which is introduced into the motor vehicle door together with the window pane, will then be held in the first position due to the positioning means.

According to one embodiment of the invention, the positioning means are releasably connected to the second component. The detachable connection of the means for positioning the first component with the second component has the advantage that the first position can be defined by the position of the second position, that is to say by the position of the first component in its original position. Consequently it is ensured that the second component can always be moved in the same way from the second position to the first position. This is particularly important when the implementation of the second component from the second position to the first position by means of a robot.

According to one embodiment of the invention, the first component has a receptacle for the means for positioning. The first component can thus at least partially accommodate the means for positioning and thereby assume the first position.

According to one embodiment of the invention, the first component is glued to the window pane or the first component is latched with a hole in the window pane.

According to one embodiment of the invention, the first component and the second component are screwed together or latched together.

According to one embodiment of the invention, the window pane projects beyond a door sill when the first component is in the first position. With a completely or almost completely retractable window pane, the window pane does not protrude in its fully open position or almost does not extend beyond the door sill, so that mounting in the fully open position is difficult. The first position for the first component is now chosen so that the window glass protrudes beyond the door parapet, even if it is a window with a large glass drop, in particular with a glass drop of 100%. In the installation position, therefore, the projecting beyond the door parapet portion of the window can be comfortably grasped, which greatly simplifies the installation of the window or the driver.

According to one embodiment of the invention, the first and the second position are at the level of a central region of the door module. The second component is ideally detachable in the middle position of the door module in the second position. xed. The door module must have a relatively large hole for mounting the first and second components. Since a hole in the central region of the door module does not lead to a reduction in the stability or strength of the door module, this area is therefore particularly well suited for mounting the driver.

According to one embodiment of the invention, the second component is movable from the second position to the first position by a movement that is substantially perpendicular to the direction of movement of the built-in windowpane. The first position is thus also accessible through the hole in the inner door panel. Thus, the first and second components can be installed through the hole from the side of the door module facing the components.

According to one embodiment of the invention, the first component and the second component consist essentially of plastic.

In another aspect, the invention relates to a method of mounting a driver of a power window assembly in a motor vehicle door. The method according to the invention has the step of fixing a first component of the driver to a window pane. Furthermore, the introduction of the window pane is carried out in the motor vehicle door, wherein the first component is brought into a first position. In addition, a positioning of a second component of the driver takes place at a second position of the motor vehicle door. In a further step, the repositioning of the first component takes place from the second position to the first position. In the first position, a connection of the first and the second component takes place.

In a further aspect, the invention relates to a first component for a driver of a window regulator assembly of a motor vehicle door with means for fixation on a window pane, with means for fixing a second component of the driver and with means for receiving positioning means of the second component. The first component is characterized in that the first component with the window pane can be installed in the motor vehicle door. This has the advantage that the first component, for example, by an adhesive connection, can be fixed to this before mounting the window. The first component is connected in situ to the second component. The built-in window can then be removed very easily again, since only the first component must be separated from the second component for removal and then the window pane with the first component can be removed from the vehicle door.

In a further aspect, the invention relates to a second component for a driver of a power window assembly of a motor vehicle door having means for temporarily attaching the second component to a motor vehicle door in a second position, comprising means for positioning a first component in a first position after mounting the second component the second position and with means for fixing the second component to the first component.

In another aspect, the invention relates to a tool for mounting a driver of a power window assembly of a motor vehicle door, wherein the driver has a first and a second component, wherein the first component is fixed to a window pane in a first position in the motor vehicle door, wherein the second component is releasably attached to the motor vehicle door at a second position, the tool having means for translating the second component from the second position to the first position. The tool further comprises means for holding the second component, wherein the means for holding fix the second component such that, in the implementation, the alignment of the second component in the plane perpendicular to an axis is maintained, the axis passing through the first and the second components second position is given.

Corresponding elements of the embodiments described below are identified by the same reference numerals.

FIG. 1 shows a side sectional view of a window lift arrangement 100. The window lift arrangement 100 in this case has a first component 102 of a lift mechanism. mers and a second component 104 of the driver. The power window assembly 100 further includes a windowpane 108. For mounting the power window assembly 100 in a motor vehicle door, the first component 104 is secured to a door module 106 of the motor vehicle door in a second position, eg by means of a threaded connection. The first component 102 is fixed to the windowpane 108 and, together with the windowpane 108, inserted into the motor vehicle door so that the first component 102 is in a first position.

The attachment of the second component 104 to the door module 106 is released and the second component 104 is moved from the second position to the first position. The first component 102 is then connected to the second component 104 in the first position, for example by means of screws or clip connections.

The second component 104 has a receptacle 112 for a cable of the window regulator assembly. Typically, the second component 104 further includes another receptacle for the cable located at the bottom of the second component 104. The rope is, for example, a circulating rope, wherein one end of the rope is fixed in the receptacle 112 and wherein the other end of the rope is fixed in the further receptacle. Depending on the direction of rotation of the rope, the cable pulls on the fixation on the receptacle 112 or via the fixation on the further receptacle on the driver and thus moves the window pane 108 upwards or downwards. The cable ends are ideally fixed in the corresponding receptacles when the second component 104 is in the second position, that is, when the second component 104 is attached to the door module 106. After detaching the second component 104 from the door module 106, the second component 104 rotates in the plane perpendicular to the plane of the drawing of Figure 1 due to the tensile forces exerted by the rope on the second component. To counteract the tensile forces, a tool 110 is used, with which one can engage in the second component 104. In this case, the second component 104 is engaged by the side opposite the first component 102. For this purpose, the door module 106 has a corresponding opening or a hole on. The tool 110 may then further be used to move the second component from the second position to the first position. When using the tool, it is ensured that the second component 104 does not twist in the plane perpendicular to the plane of the drawing so that it can then be connected to the first component 102 as intended. The tool 110 will be described in more detail below. For example, it may be attached to the second component 104 by a robot, and the robot then uses the tool to guide the second component from the second position to the first position.

FIG. 2 shows in a flow chart essential steps of the method according to the invention for mounting a driver of a window regulator arrangement in a motor vehicle door. In step 200, the fixation of a first component of the driver takes place on a window pane. In step 202 then follows the introduction of the window in the motor vehicle door, wherein the first component is brought into a first position. Further, in step 204, the positioning of a second component of the driver at a second position of the motor vehicle door follows. In step 206, the second component is repositioned from the second position to the first position, and in step 208, the first and second components are connected.

Figure 3 shows a side sectional view of a window regulator assembly 100. In the second component 104, a pin 114 is inserted, which projects through the second component. For this purpose, the second component 104 has a (precisely fitting) bore (not shown in FIG. 3) which can receive the pin 114. The pin 114 serves to position the first component 102 in the first position. When inserting the window pane 108 with the first component 102, the window pane 108 or the first component 102 can be sunk so far in the door until the first component 102 engages the pin and therefore can not be sunk deeper into the door. The pin 114 thus holds the first component 102 in the first position. By attaching the pin 114 to the second component 104, which in turn in the second position on the door module 106th is fixed, thus the first position for the first component 102 is predetermined. The window pane or the first component can not move in the direction predetermined by the longitudinal axis of the pin 114, since the window pane is held in this direction by guide rails, for example. The second component 104 can now be moved along the pin 114 from the second position to the first position. This can be accomplished, for example, by a robot that holds the pin and pushes the second component along the pin 114 to the first position. In the first position, the first component 102 and the second component 104 are then connected together. Subsequently, the pin 114 can be removed.

Figure 4 shows a perspective view of a door module 106 to which the second component 104 is mounted in the second position. The door module 106 itself is a component of the motor vehicle door, in which, for example, the window lifter arrangement is accommodated. As can be seen in FIG. 4, the second component 104 is attached to the door module. From the plane of the drawing of FIG. 4, the pin 114 protrudes, which is used to position the first component in the first position. The second component 104 also has two bores 118 and 120. The two bores 118 and 120 serve to accommodate the further tool 110 described above, with which the second component 104 can be moved without being displaced by the forces applied to the second component 104 by the cables attached to the second component 104 Component 104 acts, turns.

FIG. 5 shows a perspective view of the first component 102 in the first position and the second component 104 in the second position. As previously described in FIG. 4, the second component 104 is attached to the door module 106 in the second position. A pin 114 is attached to the second component 104. The first component is installed together with the glass pane 108 in the motor vehicle door. When installing the window pane 108 with the component 102, these are sunk in the door until a recess 122 in the first component engages the pin, whereby the window pane is no longer in the door sink. As shown in FIG. 5, the first component 102 faces the second component 104. The second component 104 can now be moved from the second position by a movement which is substantially perpendicular to the direction of movement of the window pane in the first position. In the first position, the first component 102 and the second component 104 are then joined together, for example, with screws or by means of a clip connection. The pen 114 is then removed.

Figure 6 shows the assembled first and second components 102 and 104 in the first position. In FIG. 6, it can be seen that the door module 106 has a hole 124, which makes it possible to engage the second component 104 from the side behind the door module 106 with the previously described tool and then move it from the second position into the one shown here to move shown first position.

FIG. 7 shows an embodiment of a first component 102 according to the invention. The first component 102 has a receiving slot 126 for the window pane. The receiving slot 126 serves to receive a lower edge of the window pane, wherein the lower edge is glued into the receiving slot 126, for example. Alternatively, the receiving slot may comprise means for forming a latching connection. The lower edge of the window pane can also have a hole, in which the means for forming a latching connection engage, whereby the first component 102 is fixed to the window pane. The first component 102 further includes the recess 122 in which the pin 114 can be partially received.

FIG. 8 shows an embodiment of a second component 104 according to the invention with the receptacle 112 and a further receptacle 128 for a cable of the window regulator arrangement. This is usually a circumferential rope, one end of which is fixed in the recess 112 and the other end is fixed in the recess 128. Due to the geometrical position of the recesses 112 and 128 relative to each other, the second component 104 tries to In order to align the force relationships of the transmitted by the two cable ends on the recesses 112 and 128 forces. In order to be able to hold the second component 104 in the intended orientation after releasing the second component from its fixation on the motor vehicle door, the second component also has, as mentioned above, the bores 118 and 120. In the holes 118 and 120 can be engaged with the tool for mounting, which can be compensated by the tool transmitted through the cable ends forces and whereby the second component 104 from the second position to the first position, as described above, can be brought , The second component 104 also has a (precisely fitting) bore 134. The bore 134 is, as already mentioned in the description of Figure 3, for receiving the pin.

FIG. 9 shows a perspective view of the first and second components 102 and 104 and the tool 110 for assembly. The assembly tool 110 has the pin 114. The pin 114 passes through the second component 104 and defines the first position for the first component 102 as previously described. The tool 110 further includes two bolts, only the bolt 130 being visible in FIG. 9. The bolt 130 engages the bore 118 when the pin is fully inserted into the second component. The other, invisible bolt engages in another hole, which is also not visible. The other bore or bolt is located slightly below the bore 118 and the bolt 130, respectively. The second component 104 is then moved from the second position to the first position where the second component 104, as shown in FIG the first component 102 is connected. The pin 114 is then removed with the tool 110 from the driver formed by assembling the first component 102 with the second component 104. The corresponding direction of movement in the removal of the pin 114 is indicated in Fig. 9 by the arrow.

FIG. 10 shows a tool 110 for mounting the driver. The tool 110 has the pin 114, as well as bolts 130 and 132. As previously mentioned, pin 114 serves to position the first component in the first position, if it is attached to the second component accordingly. The bolts 130 and 132 of the tool 110 engage in the holes 118 and 120 of the second component. In the implementation of the second component from the first position to the second position can then be applied to the pin 114 torque (eg by a robot), so as to ensure that the second component is not due to the forces acting on the ropes of the window regulator rotates. The second component can then be brought with the tool 110 from the second position to the first position. The pin 114 further includes another second pin 116 which pierces the pin 114 transverse to the longitudinal axis of the pin 114. The tool 110 is guided with the corresponding orientation of the second pin 116 through the bore 134 (see Fig. 8). The bore 134 has to the second pin 116 complementary notches on (these are hinted in Fig. 8), so that the pin 114 can be passed only with a corresponding position of the second pin 116 with respect to the notches through the bore 134. When the second pin 116 is located behind the bore 134 as seen from the direction of movement, then by rotating the pin 114 about its longitudinal direction, the bolts 130 and 132 can be inserted into the holes 118 and 120 of the second component 104. Due to the rotation of the pin 114, the second pin 116 is then in a position that no longer allows the pin 116 to be pulled out of the bore 134. This can be prevented, for example, that the second component 104 dissolves in the movement from the second position to the first position of the pin 114.
