Description

The invention relates to a window regulator assembly of a vehicle, wherein the window regulator assembly comprises a carrier element, wherein the carrier element has a substantial plate-shaped design with a normal direction, wherein at least one unit is arranged on the carrier element, wherein the unit comprises a guide rail, a slider which is movably arranged at the guide rail along a longitudinal axis and at least one pulley arrangement for redirecting a cable, wherein the carrier element has an edge region and wherein a part of the unit extends beyond the carrier element in a direction perpendicular to the normal direction. Furthermore, the invention relates to a method for mounting such a window regulator assembly. A window regulator assembly of the generic type is known from EP 4 269 737 At. Such an arrangement is used in a vehicle door. The principle of this design is shown in figures 1 and 2. Figure 1 shows a top view of a previously known window regulator assembly 1; figure 2 shows a perspective view of a part of the window regulator assembly. The window regulator assembly 1 has a carrier element 2 which has substantially a plate-like design. The normal direction N stands perpendicular on the base plane of the carrier element 2 and thus normal on the drawing plane of figure 1. A unit 3 is arranged on the carrier element 2. This can be at least partially a separate part 3 which is mounted on the carrier element 2; it is also possible that the unit 3 is formed at least partially from the material of the carrier element 2 by a forming process (e. g. deep drawing). The unit 3 comprises a guide rail 4 on which a slider 5 can move in a longitudinal direction L. For the movement of the slider 5 pulley arrangements 6 are employed; a cable 7 is guided around the pulleys of the pully arrangements 6. The cable 7 is driven by a drive unit 18. Thus, each of the pulley arrangements 6 has a pulley which is rotatably mounted in order to guide and redirect a cable; the movement of the slider 5 is initiated by the cable 7. The slider 5 includes a window clamp arrangement (not shown) which is engaged with the window of the vehicle. As can be seen in figure 1 and in figure 2, the unit 3 extends beyond the edge region 8 of the carrier element 2 in a direction E which is perpendicular to the normal direction N; this direction E corresponds substantially to the longitudinal direction L in which the slider 5 moves. For an adequate operation, it is necessary that the window regulator assembly 1 is provided with a seal 11 before the assembly is mounted at a vehicle door. Normally, most of the circumference of the carrier element 2 is provided with a FIPG seal (Formed-In-Place-Gasket). Due to the extension of the unit 3 beyond the edge region 8 of the carrier element 2, the application of such a seal is often not possible around the whole circumference of the carrier element 2. Accordingly, as shown in figures 1 and 2 (see especially figure 2) the necessary seal 11 is designed as a FIPG seal 11' which covers most of the circumference of the carrier element 2 and a separate seal 11" which is employed to seal the region of the edge of the carrier element where the extended part of the unit is arranged. The drawback of this design is that the installation of the seal 11 is quite complicated and costly. Extra costs are caused due to the required separate seal in addition to the FIPG seal and the assembly process of the seal. Also, special machines are required to provide the seal in an automated process. The invention is therefore based on the object of designing a generic window regulator assembly in such a way that an easier and more cost effective design is provided which allows an efficient sealing of the carrier element in a cheap manner. So, the production costs for the window regulator assembly should become lower. Thus, the provision of an effective and cheap sealing element around the whole circumference of the carrier element should be possible. The solution of this problem by the invention is characterized in that the unit comprises a first section which does not extend beyond the carrier element in the direction perpendicular to the normal direction and comprises a second section which extends in the mounted state beyond the carrier element in the direction perpendicular to the normal direction, wherein the second section is detachably arranged at the carrier element and/or at the first section. Thus, the proposed solution provides the possibility that the complete seal is arranged at the carrier element before the second section of the unit is mounted. So, the seal can be applied around the whole circumference of the carrier element in an easy and cost effective manner, before the second section of the unit is mounted. The direction perpendicular to the normal direction is preferably the longitudinal direction in which the guide rail extends. The first section of the unit ends preferably with a distance before reachi
