DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS

(8) In FIG. 1, a schematic view of a visible side of a trim part 11 is illustrated. FIG. 2 shows a side view of the trim part 11. In FIG. 3, a rear side of the trim part 11 according to FIG. 1 is illustrated.

(9) This trim part 11 is, for example, formed as a pillar panel or a trim panel for a motor vehicle. The trim part 11 consists of a cover part 12 having a visible surface 14. This cover part 12 is at least surrounded by a sealing element 16. A support part 18 (FIG. 3) is provided on a rear side relative to the visible surface 14 of the cover part 12. Fastening elements 19, such as, for example, clips or the like, are provided on this support part 18 to fix the trim part 11 to a vehicle chassis.

(10) An upper fastening element 19 can, for example, be adhered directly to a rear side of the cover part 12so to a fastening surface 25or fastened with an overmoulding. The further fastening elements 19 in the lower region of the trim part 11 are arranged on a portion of the support part 18. Alternatively, the upper fastening element/s 19 can likewise be arranged on the support part 18.

(11) The support surface 18 is formed from a plastic with high mechanical resistance and good impact resistance and has, for example, a flexural modulus greater than 1000 N mm2. For example, the support material is made of PC, ABS.

(12) The cover part 12 is formed from glass. This glass can also be coated. This glass can also be tinted. Such a glass has a high weather resistance and scratch resistance. A single-pane safety glass, a tempered glass or a laminated safety glass can be provided as a glass. The cover part 12 can also be curved.

(13) In FIG. 4, a sectional view along the line I-I in FIG. 1 is illustrated. The support part 18 has, for example, a sealing lip 21 which is injected on or adhered, made in particular of EPDM or TPE, which is orientated towards the chassis side or fastening side of the trim part 11. The sealing element 16 is provided on an outer side of the support part 18. This sealing element 16 surrounds at least both longitudinal sides of the cover part. The sealing profile preferably surrounds the cover part 12 in a fully circulating manner. The sealing element 16 can be formed, for example, from EPDM, in particular an EPDM profile. Opposite the visible surface 14 of the cover part 12, the cover part 12 has a fastening surface 25. This fastening surface 25 forms a rear side of the cover part 12 which is formed of glass. This fastening surface 25 can also be coated for decoration purposes. Alternatively, the cover part 12 can also be coloured for decoration purposes.

(14) The cover part 12 is connected to a fixing portion 28 of the support part 18 by an adhesive bond 27. This adhesive bond 27 can be formed as a plastic adhesive bond, in particular a PU adhesive bond, by application of an adhesive bead.

(15) In this embodiment according to FIG. 4, it is furthermore advantageously provided that an end side 30 of the cover part 12 as well as an edge region 31 of the fastening surface 25 has an overmoulding 32. This overmoulding 32 advantageously fully surrounds the end side 30, so that this overmoulding 32 ends flush with the visible surface 14. The overmoulding 32 extends advantageously at least along both longitudinal end sides of the trim part 11. Additionally, one or both narrow sides of the cover part 12 can likewise be surrounded by the overmoulding 32. The overmoulding 32 preferably extends fully along the end sides 30 of the cover part 12 to form an edge protector.

(16) The sealing element 16 is inserted and preferably held in a latching manner between the cover part 12 and the support part 18.

(17) Alternatively, in this embodiment according to FIG. 4, the end side 30 of the cover part 12 can be provided free from an overmoulding 32, so that the sealing element 16 lies directly on the end side 30 of the cover part 12, as subsequently further described in FIG. 6.

(18) In FIG. 5, an alternative embodiment of the trim part 11 to FIG. 4 is illustrated. In this embodiment, the cover part 12 is connected to the support part 18 by a back injection 34. For example, a TPE or PU back injection can be carried out. This back injection 34 can extend only along the fastening surface 25, so that an edge region 31 and/or the end side 30 is free of the back injection 34. Alternatively, the back injection 34 can also include the end side 30, so that protection for the end side 30 of the cover part 12 is again provided by the back injection 34. The sealing element 16 is in turn fastened to the cover part 12 by clipping or clamping between the support part 18 and the back injection 34.

(19) In the embodiment illustrated in FIG. 5, the support part 18 and the cover part 12 are formed as an insertion part. These are inserted into a tool, in order to subsequently back inject the cover part 12 through one or several injection points and connect to the support part 18. Alternatively, the cover part 12 can be inserted into a multi-component injection moulding tool, in order to subsequently form the back injection 34 and thereafter the support part 18 in a two- or multi-component injection moulding process.

(20) In FIG. 6, a further alternative embodiment of the trim part 11 to FIG. 4 is illustrated. In this embodiment, unlike FIG. 4, instead of the use of adhesion 27, in particular by means of an adhesive bead, a double-sided adhesive tape 36 for adhesion of the cover part 12 to the support part 18 is provided. The sealing element 16 is held between the support part 18 and the cover part 12 by clipping or clamping. The sealing element 16 thus preferably has a sealing portion 38, which is formed in an L-shape, so that this sealing portion 38 lies on the end side 30 and the edge region 31 of the fastening surface 25 on the cover part 12. The sealing portion 38 preferably also comprises sealing lugs or projections 39, so that a sealing arrangement of the sealing element 16 to the cover part 12 is provided.

(21) A further alternative embodiment of the trim part 11 can be formed by welding a fastening portion, which adjoins the cover part 12, to a fixing portion 28 of the support part 18. Such a fastening portion can, for example, correspond in its planar extension, according to the adhesion illustrated in FIG. 4. Alternatively, such a fastening portion can also by formed by a back injection 34 according to the embodiment in FIG. 5, wherein this back injection does not engage behind the support part 18, but instead is welded by means of the fixing portion 28. Furthermore, the alternative embodiment of the welding of the fastening element on the cover part 12 can be carried out with the fixing portion 28 of the support part 18 analogously to the embodiment in FIG. 6, according to which the fastening portion is injected to the cover part 12 corresponding to the extent of the adhesive tape 36.

(22) The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
