Description

The present invention relates to a fastening arrangement comprising a first component and a second component attachable thereto. The invention further relates to a motor vehicle equipped with such a fastening arrangement. During vehicle assembly, particular emphasis is placed on the precise alignment of decorative elements, as these are largely responsible for the vehicle's final appearance. Common methods for attaching such trim strips or elements include gluing or clipping them to the vehicle's body. However, with gluing, there is a risk, at least until the adhesive hardens, that the decorative element will shift and therefore cannot be properly aligned on the vehicle. Similarly, with clip connections, where the decorative element is attached to an opening in the body via a clip, the necessary clearance between the clip and the opening can prevent a precisely defined installation position. From the DE 10 2004 035 719 A1 A fastening arrangement is known comprising a first component and a second component attachable thereto, wherein at least one elongated hole-like opening is provided in the first component, into which at least one engagement element arranged on the second component engages in a self-positioning manner, such that positioning elements arranged on the engagement element, which are designed as longitudinal and transverse webs, are supported on an edge of the elongated hole-like opening. From the DE 33 34 487 A1 A blind fastener is known. The present invention therefore deals with the problem of creating a fastening arrangement which, on the one hand, enables a reliable fastening of a first component to a second component and, at the same time, allows for the exact positioning or alignment of the two components relative to each other. This problem is solved according to the invention by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims. The invention is based on the general concept of creating a fastening arrangement with two components to be fastened together, wherein the first component has at least one elongated opening into which an engagement element arranged on the second component is pressed for mounting the fastening arrangement. The engagement element not only ensures a reliable connection between the first and second components, but also has so-called positioning elements by means of which the engagement element is supported against an edge of the through-hole and thereby aligns itself with respect to the opening. The positioning elements on the engagement elements are such that they are matched to the elongated openings on the first component in such a way that when the engagement elements are pressed into the openings for fastening the second component to the first component, the second component is aligned relative to the first component. Separate alignment is therefore not necessary, so that the alignment of the second component is achieved by simply pressing the second component onto the first component while simultaneously pressing the engagement elements arranged on the second component into the openings arranged on the first component. Furthermore, a reliable connection or fastening of the second component to the first is possible through the clamping and/or locking action of the engagement elements in the corresponding openings of the first component. The proposed fastening arrangement thus not only enables very simple attachment of the second component to the first, but also allows for the automatic alignment of the two components to be fastened to each other during the manufacturing process. This eliminates the need for time-consuming adjustment or alignment during assembly. At the same time, such a fastening arrangement is extremely cost-effective to manufacture, as the first component only requires corresponding elongated holes that interact with the plastic engagement elements provided on the second component. The positioning elements are designed as longitudinal and transverse ribs. This design allows the engagement element to be supported at multiple points along the opening edge, thus simultaneously self-centering. The design of the positioning elements with longitudinal and transverse ribs is structurally very simple and therefore cost-effective to manufacture. According to the invention, at least one longitudinal and/or at least one transverse web of an engagement element is designed as a scraping element which can be pressed into the associated opening with material removal. This means that a clear cross-section of the opening in the first component is usually is likely slightly smaller than a corresponding outer cross-section of the engagement element arranged on the second component, so that pressing the engagement element into the opening can only occur if at least minimal material is removed from the longitudinal and/or transverse webs of the engagement element.
