Problems solved by technology
[0003] When fixing two components in this way, the problem often arises in practice that undesired stresses and deformations are introduced at least locally into at least one of the two components via the fixing element
[0005] The device described in DE 198 47 268 A1 with a set-back connection section on one of the two components to be connected to each other also overcomes the clamping to a certain extent here, which results in the following way: when the When several identical fastening locations with two openings are provided on two components,—depending on manufacturing tolerances—the openings on the two components that are to be formed superimposed on each other are not aligned exactly with each other

Embodiment Construction
[0051] Figures 1A-1C and 2A-2B show the invention according to the invention for a motor vehicle with a first component in the form of a (unit) support T and a second component in the form of a guide rail FS as part of a motor vehicle window lifter (not shown further). The first embodiment of the assembly. In this case, the guide rail FS can be fastened in the region of two pairs of fastening points B1 , B2 and B3 , B4 and thus to a total of four fastening points on the carrier T, wherein the fastening points B1 , B2 and B3 , B4 They are spaced apart from each other along the longitudinal extension of the guide rails FS. Thus, one pair of fixing points B1, B2 is located in the area of the (upper) end of the guide rail FS, while the other pair of fixing points B3, B4 is provided in the area of the opposite (lower) end of the guide rail FS.
[0052] Protruding sections or projections 6.1 , 6.2, 6.3 or 6.4 are respectively provided on the fastening points B1 to B4, which se...

The invention relates to an assembly for a motor vehicle comprising at least a first component and a second component, for example a carrier and a guide rail of a window lifter which are fixed together by means of at least one fastening element, in this case by a plurality of rivets. A fastening element engages into openings of which one opening respectively is formed in a receiving portion of the first component and one on a protrusion of the second component, wherein a protrusion respectively protrudes in an associated receiving portion and a flexible or elastic edge section of a receiving portion can be shifted in the direction of the associated protrusion. The at least one edge section that can be shifted in a flexible manner is designed and provided for compensating manufacturing tolerances, such that the two components automatically align to one another in the area of the flexible edge section during the fastening process and can form a solid connection as intended, wherein the protruding section is locked in the receiving portion by the edge section which is shifted and pushed against the protruding section.
Description
technical field [0001] The invention relates to an assembly for a motor vehicle having at least one first and a second component and to a method for fastening two components of a motor vehicle assembly to one another. Background technique [0002] Fastening elements, such as screws or rivets, are often used for connecting components of a motor vehicle assembly, which clamp the two components together and in which at least one of the two components passes through (through) the opening. Such fastening elements thus respectively engage into openings on the two components in order to fix the two components in relative position to each other. For example, the first opening on the first component is formed as a through opening and the second opening on the second component is formed as a through opening or a blind hole opening. Here too, the opening on a component can first be formed by providing fastening elements, as is the case, for example, with self-tapping screws as fasteni...
