Description

The invention relates to a device for fastening a sliding window of a motor vehicle a guide device of a window lifter according to the Preamble of claim 1 and is characterized by simple and safe assembly and adjustment the window pane, while at the same time the functional reliability the window pane is raised.

DE 43 16 651 A1 discloses a fastening device to connect a driver of a window lifter with a window pane known in which a fastener of the driver in the form of a bolt a receiving opening reaches through inside the window pane. The bolt has a head with an enlarged one in relation to the shaft Diameter and becomes perpendicular to the disc plane through the correspondingly trained in diameter Insert the opening of the window pane and then moved to a leadership area. The leadership area corresponds to the shaft diameter dimensioned.

From DE 31 08 244 A1 a coupling device is between a window lifter and a window pane of a motor vehicle known, consisting essentially of one at the bottom Edge of the window pane fastened holding element and at least there is a clutch shoe with locking means is equipped and towards one with a fit Locking elements provided with the window mechanism connected coupling element protrudes. When merging the parts to be connected are elastic Deformation of at least one of the coupling elements to Clipable connection through positive interlocking the locking means is made.

The disadvantage, however, is that the connection the spreadable between window pane and window regulator Area must have a minimum elasticity so that the Locking elements in a positive engagement can kick. This elasticity also harbors the danger that in the case of large tensile loads such as, for example with a window pane frozen on the frame can occur, the locking elements again except Intervention.

The window regulator device could then no longer fulfill its task. Beyond that it is difficult to bring the locking elements into position so precisely that they are stand restable. It is therefore necessary to slide the window pane back and forth in the X direction often necessary to achieve positive locking.

From JP 6-135228 A is a device for connecting a window pane to a window regulator known, the U-shaped extending parallel to the lower edge of the window lifter Profile pieces used, the free legs of the D-profile inward hook-shaped Have extensions. These profile pieces are assigned to fit into the U-shaped cavity snap-in coupling pieces that are attached to the lower edge of the window pane. For To facilitate engagement, the free ends of the coupling pieces are wedge-shaped barbed extensions can reach behind the extensions of the U-profile. Nevertheless, it is in the It is usually necessary for the worker to exert pressure on the window pane in the direction of assembly. to the necessary form-fitting. The position between the window regulator and Window pane fixed in accordance with the provided holes and grooves. An adjustment of the Window pane in the X direction (vehicle longitudinal axis) for the purpose of setting an ideal one Position is just as little possible as with the version described first.

Another snap-on disc connection using elastically deformable and regions that can be pivoted as a result are described in DE 44 23 440 A1. Form the swiveling areas the upper end of the recesses of two parallel holding legs, in the one Connection element of the window pane can snap into place. As a connecting element in a bolt-bearing bolt or a glued on or out of the window pane self-molded element.

This fastening device is also disadvantageous in that the elastically designed areas of the Holding legs have a reduced resilience. Thus, there is a high trigger force the risk of loosening the connection.

The invention has for its object one in the window assembly on the window lifter itself Locking device to design so that the weight of the disc for interlocking the Form-fit elements are sufficient and the window pane can be adjusted in the X direction is guaranteed. In addition, the load capacity of the fastening device in the withdrawal direction the window pane compared to comparable known devices can be significantly increased.

According to the invention, the object is achieved by the characterizing features of patent claim 1 solved. The subclaims give preferred variants of the invention. So there is one Insertion opening for insertion of the locking element in the elongated, in the X direction extending recess provided so that no elastically movable or spreadable areas of the fastening device are necessary. This was done through a functional The fastening device can be divided into two areas, namely one area exclusively for the insertion of the locking element in the form-firing area of the assigned part the fastening device and in another area exclusively for the transmission of Window lifter adjustment forces.

The transfer of the locking element from the insertion area to the elongated The recessed fastening area is formed by a sliding movement in the X direction. This shifting movement can be done by the worker or automatically by aligning the Window pane in the frame of the vehicle door during the first closing function of the window lifter be made. For a safe function of the fastening device according to the invention it is important that the vertical axes of the insertion area (the insertion opening) and the After completion of the pane assembly, the locking elements are at least as far apart that one sufficiently large coverage between the locking element and the elongated recess and a sufficient load-bearing capacity of the fastening device is thus ensured.

In addition, means must be provided to prevent accidental pouring out of the Snap element out of the elongated recess and into the insertion opening prevent. This would cause the fastening direction to lose its functionality. To one hand not to hinder the assembly movement, and on the other hand a return movement of the Block locking element are suitable in a simple manner sawtooth-shaped Locking elements on the one hand on the locking element carrying part and on the other hand on the the elongate recess-carrying part is attached and pressed together elastically. The steep flank of the sawtooth profile knows against the mounting direction of the locking element. The spring elasticity of the engagement of the locking elements allows easy assembly of the Fastening device, since the toothing elements in the mounting direction on each other easily can slide.

The width of the insertion opening and the width of the latching element are expediently correct largely match. To facilitate the introduction of the locking element, the locking element knows at least in its lower area a rounded, possibly circular contour and the Insertion openings are conical guide surfaces opening in the direction of the latching element upstream.

The two parts of the fastening device designed according to the invention can optionally be used with the Window pane or connected to the guide device of the window pane. This means, either the locking element is on the window pane and the associated elongated recess is attached to the guide device of the window regulator or vice versa. Ideally, that forms with part of the guide device connected to the driver of a cable window lifter one-piece homogeneous component. The part to be connected to the window pane is also formed in one piece and, for example, glued to the lower edge of the pane or over one Disc hole inserted in a form-fitting manner near the lower edge of the disc. When using Plastic washers is also the shape of the corresponding part in the material of the Window pane possible.

Because the forces acting on the window panes vary greatly from vehicle to vehicle The requirements for the stability of the force-transmitting elements vary correspondingly strong. So it may be sufficient in many cases, the parts of the invention To manufacture fastening device from plastic. In other cases, you have to look for more resilient Use parts made of light metal casting. Should be in such metal parts from constructive For reasons not to have a spring range integrated that provides sufficient travel for the Allows locking elements, so a separate spring element must be used, which in the Disk mounting allows the locking elements to slide together. Beyond that but other types of safety devices to avoid a return movement are also conceivable, e.g. Screw lock, adhesive.

The schematic representations of Figures 1a to 1c illustrate the principle in a simple manner of the present invention. Accordingly, the fastening device consists of a first part a locking element 2 and a second part 1 with a horizontally extending, elongated Recess 12, which serves as a guide link and fastening area for the locking element 2, after this by a laterally arranged and facing the locking element Insertion opening 10 was inserted.

The invention can be used wherever the window pane has such a sufficient lateral Slidability has that the locking element 2 over the insertion opening 10 in position can be brought. Conical guide surfaces 11 formed in front of the insertion opening 10 facilitate the so-called blind assembly, in which the connection is made without visual control. On Another advantage is the tool-free assembly, especially for the invention Suitable for use on so-called module carriers that provide a moisture-proof separation between form an outer wet space and an inner dry space of the vehicle door. Thereby Connection of the window pane to the window regulator no tools are required, too assembly openings in the partition and their subsequent sealing are dispensed with.

Figure 1a shows the beginning of the assembly process based on a vehicle door with one shown double-strand cable window lifter, the part 1 the area of the entrainer should represent, which is positively connected to the rope loop of the window regulator. First, the window pane 3 is inserted through the door shaft into the inner door body 4 (Assembly direction 30) and lowered until it is in a disc hole bolt-shaped locking element 2 has penetrated into the insertion opening 10 and on the base the elongated recess 12 rests. In a second assembly step there is a horizontal displacement movement of the window pane 3 in the mounting direction 31 until they are Has reached the target position. This is associated with a displacement movement of the locking element 2 in the Fastening area (recess 12) of part 1. Thus, the vertical central axes 100, 200 of the insertion opening 10 or the locking element 2 a distance. To one Reset movement of the locking element 2 against the mounting direction 31 and the associated To rule out the risk of unlocking the window pane, there are special ones that act on one side Locking elements are provided, which are explained in more detail in the following exemplary embodiments become.

At this point, however, it should be pointed out that with double-strand cable window lifters Locking elements only required on the fastening device of one of the guide rails are. The locking element of the other fastening device should be in the elongated recess 12 move "freely" and thus compensates for tolerances in the parallelism of the two guide rails.

The fastening device according to Figures 2a to 3b is structurally designed so that its Have individual parts 1, 2 manufactured well by plastic injection. The high degree of integration creates that Requirements for the fastening device, including the driver, with Nipple chamber 19 and hook 18, only consists of two parts 1, 2. Part 2 includes a bolt-shaped locking element 20a, which is asymmetrical on a connecting part 21a with a web 22a stores. The web 22a is assigned the lower edge of the window pane 3, which is on the can support raised support surfaces 24a, 25a. Are on the lower edge of the web 22a Locking elements 23a formed, which after assembly with the counter-toothing 17 of the part 1a are engaged. The locking element 20a has on the side of the connecting part 21a, that rests on the surface of the window pane 3, a greater height than on the other (not visible side) the difference corresponds approximately to the slice thickness. It is advantageous to have part 2a equipped with a captive lock so that it does not clasp in the disc hole can fall out.

The rail-side part is shown in Figures 2a and 2b in two views. It consists of the parallel legs 14, 15 which are connected to one another via the base 13. To one De-molding of the injection molds with the desired high degree of integration the leg 14, which only carries the recess 12aa on its inside, shortened training. In the inside of the other leg 15 are next to the Recess 12a also the insertion opening 10a with the conical in front Guide surfaces 11a molded. On the outside of the leg 15 carries the hook 18, which the Grip the guide rail in a form-fitting manner and the nipple chamber 18 via a form-fitting one Connection to the power-transmitting rope loop of the window regulator is established.

During the pane assembly, the part 2a mounted in the area of the lower pane edge enters the space of part 1a. The latching element 20a first comes into contact with one conical guide surfaces 11a before it passes through the insertion opening 10a. Upon reaching the the lowest position also sawtooth-shaped locking elements 17, 23a come into contact with each other Intervention. When the locking element 20a is moved into the recesses 12a, 12aa (in analogy to FIG Assembly direction 31) the locking elements 17, 23a slide on one another, the web 22a is arched upwards in the direction of the lower edge of the pane 300. A reset movement is through the sawtooth-shaped contour of the locking elements 17, 23a blocked.

The sectional representations 3a and 3b show the position of the latching element 20a in the recess 12a after installation of the pane. The fastening device according to Figures 4a and 4b shows different views after completion of the assembly and used as Part 1a on the guide rail side is a component which is connected to part 1a from FIG. 2b or 2c is identical. The other part 2b has a carrier plate 28 with a locking element 20b, on the other upper end two substantially parallel legs 27 for receiving the window pane 3 are arranged. Part 2b is usually glued to the bottom of the Window pane 3 attached.

From the sectional views of Figures 5a and 5b, the position of the locking element 20b is within the elongated recess 12a clearly visible. The shape of the locking elements 17, 23b also shows clearly that this when starting an assembly movement of part 2b starting from the The insertion opening 10b can slide onto one another into the recess 12a. In doing so the toothing elements 23b arranged on the spring web 22b upward in the direction of the gap 26b pressed. A return movement in the direction of the insertion opening 10b is due to the appropriately directed sawtooth shape of the locking elements 17, 23b prevented.

The embodiment shown in Figures 6a to 9e relocated compared to the previous described variants, the elongated recess 12c to the part 1c, which with the window pane 3 to be firmly connected, while the guide rail-side part 2c the locking element 20c wearing. In addition, the locking elements 17c and 23c were directed sideways Layed areas of parts 1c, 2c. This embodiment is also suitable for execution as Light metal casting. Because of the shortened leg 14c of part 2c during the A sufficiently large tilting movement between parts 1c and 2c is performed are so that their locking elements 17c, 23c can slide on each other if necessary.

For the rest, however, the assembly is carried out using the basic principles already described Procedure, the part 1c firmly connected to the window pane 3 Window lifter-side part 2c is fed until this via its conical guide surfaces 11 c Insertion opening 10c and the recess 12c with the locking element 20c of the part 2c engages positively. At this point it should be noted that the locking element 20c is not must have a bolt-like contour. They are also elliptical or angular contours or combinations thereof can be used. However, the use of rounded contours at least on the side of the locking element 20c, that of the insertion opening is facing.

The outside of the leg 15c in turn carries a driver area 190 with the Nipple chamber 19 and hook 18 for slidably attaching part 2c to the Guide rail of a cable window lifter.
