Plastic el i ρ for detachable fastening o of panels in motor vehicles or the like

The innovation relates to a plastic for the detachable fastening of panels in motor vehicles or ag}., With a retaining head for the panel and a sealing plate between the retaining head and several radially resilient fastening elements, such as fastening arms.

Such a plastic clip is e.g. DE-PS 28 24 008 became known. Such plastic clips are mainly used in motor vehicles for fastening panels. The latter previously consisted of a with a cardboard element laminated with a plastic skin or textile material and in connection with this, the known plastic clips performed their fastening function satisfactorily. Recently, however, plastic elements have also been used instead of these laminated cardboard elements, which at Fastening with the previously known plastic clips in the

Operation of the motor vehicle generate annoying rattling noises. This is due to the fact that between the plastic clips and the plastic elements of the cladding an assembly-related one Game is present.

The innovation is based on the task of eliminating the above deficiencies and creating a plastic clip, which wears the panels cushioned in such a way that they do not cause any disturbing noises when driving.

According to the innovation, this task is performed with a plastic clip of the type described at the outset is achieved in that the plastic clip between the holding head and the sealing plate has several molded-on, having effective, resilient spacers in the radial and / or axial direction. These springy spacers compensate for any play between the individual plastic clips and the cladding element, so that when driving Rattling noises cannot occur. This applies to both possible axial and radial play. The innovation thus advantageously enables a perfect attachment of those panels that are used as load-bearing Items contain plastic sheets.

A further development of the innovation is characterized in that the spacers are made up of thin-walled resilient tongues

are formed, which extend radially from a spacer between the holding head and sealing plate to the outside and / or axially from Extend the sealing plate in the direction of the retaining head. These When the cladding is installed, resilient tongues are placed under pretension against the embedments or inside of the Cladding element, cushion any radial and axial play and thus prevent the otherwise resulting rattling noises.

According to yet another embodiment of the innovation, the tongue-shaped spacers formed on the sealing plate can be of viewed from the side, have a triangular shape with a tip pointing in the direction of the holding head. This shaping facilitates the bending or elastic deformation of these tongue-shaped spacers when clipping in the plastic clips in corresponding openings in the cladding elements,

The innovation will then be explained with reference to the drawings of an exemplary embodiment. Show it:

Fig. 1 is a side view of a plastic clip according to FIG Innovation with tongue-shaped spacers on the sealing plate and the spacer between the sealing plate and the holding head;

The plastic clip 10 is used for the detachable attachment of a Cladding, for example in motor vehicles, which can have a plastic plate 11 (Fig. 5) as a load-bearing element, which can be laminated with a textile material (not shown), for example. In detail, the plastic clip 10 a telephone-shaped holding head 12 on which a coaxial cylindrical spacer 13 is formed on which in turn, a sealing plate 14 connects. On the inside of the sealing plate 14 are four in radially deformable fastening arms 15 are integrally formed, which conically outwards against the axis of the plastic clip extend and are connected to one another at their outer ends by a conical part 16. At 17 are the mounting arms 15 angled. When attaching the

Plastic clips 10 in a bore 18 of a supporting sheet metal part 19 put the radially resilient fastening arms 15 under bias against the inner edge of the bore 18 and fix the plastic clip 10 (including the cladding) on sheet metal part 19 *

The plastic plate 11, which, as already mentioned, forms the load-bearing element for a cladding, is on its Edge provided with numerous openings 20, into each of which a plastic clip 10 can be "screwed". To this The purpose is the holding head 12 of each plastic clip 10 with a corresponding (not shown) U-shaped recess Mistake. If the plastic plate 11 is equipped with a corresponding number of plastic clips 10, are the latter for fixing the plastic plate 11 and thus the corresponding cladding in the bores 18 of the sheet metal part 19 snapped.

To ensure that the plastic plate is properly secured against vibration 11 through the plastic lips 10 or rattling noises caused by vibrations in the To avoid the area of the cladding, each plastic clip 10 has a radial and axial play between the plastic plate 11 and the plastic clips 10 receiving resilient Spacers 21 and 22 in the form of thin-walled resilient tongues on. In detail, those are effective in the radial direction

Spacer 21 diametrically opposed integrally formed each other on the cylindrical spacer 13, while the _s viewed from the side triangular spacer 22, are likewise diametrically opposed integrally formed each other on the sealing plate 14 so that their tips point in Ricntung holding head. When the plastic clips 10 are snapped into the bores 18 of the bending part 19, the elastically deformable sealing plate 14 is pulled against the sheet metal part 19 and its angle of inclination is flattened, with its edge sealing against the sheet metal part 19 and thus sealing the bore 18 against the penetration of water .

When the plastic clips 10 are screwed into the openings 20 the Ajstandshalter 21 in the manner shown in Fig. 4 and bent over in such a way that they lie resiliently against the embedment of the openings 20. At the same time the spacers 22 bent over against the sealing plate 14 and pretensioned, as can be seen in FIGS. 4 and 5, and thereby becomes the practically inevitable axial and radial play between the plastic plate 11 and the plastic clips 10 added or compensated. 4 and 5 is only to better illustrate the innovation, the radial distance between the cylindrical spacer 13 and the opening shown in exaggerated size in the plastic plate 11.
