Embodiment Construction

[0021] figure 1 and 2 The components of the connection assembly for securing the attachment to the stand 10 are shown separately. In this case, the orientation of the individual components corresponds to the orientation in the installed state of the connection assembly. The structure of each component and its cooperating effect are described below with the fixing of the door lining of a motor vehicle on the door panel as an example. However, the invention is not limited to this application, but can also be used for other purposes.

[0022] The connection assembly comprises a pin 12 made of hard plastic, preferably POM-C (polyoxymethylene copolymer), a connecting piece 14 (stopper), made of hard plastic, preferably PBT GF (glass-fiber-reinforced polyethylene terephthalate) Butylene formate) retaining clip 16 and optionally a seal 18 made of elastic plastic, preferably TPE-V (thermoplastic elastomer vulcanizate). The connecting assembly is designed to connect an attachment (...

Abstract

The present invention relates to a connection assembly for fastening an attaching element on a support (10), comprising a holding clip (16), which can be inserted into a mounting opening (20) of the support (10) and has holders (54) for axially fixing the holding clip (16) to the support (10); and a pin (12), which can be reversibly attached to a coupling piece (14) fastened to the attachment element and inserted into the holding clip (16). The pull-off force of the pin (12) in an intermediate position of the connection assembly, in which the pin (12) has a first orientation relative to the holding clip (16), is larger than in a mounting position of the connection assembly, in which the pin (12) also has the first orientation and is inserted fully into the holding clip (16).

Description

technical field [0001] The invention relates to a connection assembly for fastening an attachment to a support, in particular for fastening a door lining to a door panel of a motor vehicle. Background technique [0002] Known connection assemblies are only able to withstand high pull-out forces to a limited extent. The pull-out force here refers to the maximum force that the connection assembly can withstand before the attachment can no longer be held on the support, opposite to the mounting direction of the attachment. If particularly high pull-out forces are required, conventional screw connections are therefore always considered, but such connections lead to time-consuming assembly and disassembly. Contents of the invention [0003] It is therefore the object of the present invention to avoid the disadvantages of screw connections and to provide an economical connection assembly which can withstand high withdrawal forces but still ensures a reversible fastening of the ...
