Fastening of trim to a window seal

Abstract

The invention relates to an element (100) for fastening trim (1) to a peripheral seal (10) of a window (11) of a vehicle, comprising at least one assembly of the clip type formed by a base (6) bearing, on the face intended to receive the trim, one or more semi-rigid clips (7), said clips comprising at least two arms between which a lug element (4) of the trim is introduced, characterized in that the fastening element (100) is formed of one piece enclosed in the peripheral seal during the moulding thereof to the window.

Claims

1. An element for fastening a trim to a peripheral seal of a window of a vehicle, comprising at least one clip-type assembly constituted by a base bearing, on a face designed to receive the trim, at least two semi-rigid clips, the at least two semi-rigid clips comprising at least two arms between which a lug element of the trim is inserted, wherein the fastening element is constituted as a single component, comprising the base and the at least two semi-rigid clips, which is integrated with the peripheral seal during molding of the latter on the window, and wherein the peripheral seal includes a wedge component on which an edge of the trim can rest, a principal body of the peripheral seal being formed with the wedge component by molding.

2. The fastening element according to claim 1, wherein the base and the at least two semi-rigid clips are composed of a same material.

3. The fastening element according to claim 1, wherein the fastening element is fastened to the peripheral seal of the window by encapsulation.

4. The fastening element according to claim 1, wherein the at least two arms of the semi-rigid clips comprise polycarbonate/acrylonitrile/butadiene styrene (PC-ABS).

Description

(1) The invention is described in detail with reference to the figures, in which:

(2) FIG. 1 shows, in section, the method of fastening by clipping according to the invention;

(3) FIG. 2 shows, in perspective, the window with the clipping element incorporated into the encapsulation seal.

(4) FIG. 1 shows, in section and schematically, the method of assembly by clipping. In this representation, the trim 1 has an exterior surface 2 designed to mask the encapsulation seal 10 of the window 11. On its face that is turned toward the seal, the trim comprises a lug 4. The fastening element is, in this example, made from plastics of ABS-PC type, produced using an injection-molding process. The material used must have sufficient flexibility to allow the clipping function and also adhesion with the plastics, preferably of encapsulation PVC or TPE type.

(5) The fastening element comprises a base 6 held in the seal at the time of the moulding of the latter. The fastening element also comprises a clip 7 designed to receive the lug 4 of the trim 1 in a semi-rigid manner. The clip 7 is integrated in the base 6 and thus constitutes a single component comprising the base 6 and the clip 7.

(6) FIG. 2 shows an arrangement of the method for fastening the edge of the window 11 in the seal 10 in the case of this method of assembly by encapsulation. The trim (not shown) is positioned after the assembly operation in question.

(7) The fastening element, as shown in FIG. 2, is held in the seal 10 during the moulding thereof on the window. Only the upper face of the base 6 comprising the clips 7 emerges outside the seal 10, and the remainder is held in the seal. The clips 7 lie outside the seal 10.

(8) The seal 10 in FIG. 2 has a wedge component 12, on which the edge of the trim rests in order to prevent contact with the bodywork of the vehicle, and an end stop 13 lying at the end in the length of the trim. The wedge component 12 and the stop 13 are produced with the principal body of the seal by molding.

(9) As shown in FIG. 2, the base 6 is constituted by a body of elongate form and of such dimensions that allow incorporation into the seal during molding. Thus, insertion into the seal is achieved easily and repeatably in the encapsulation mold. The clips 7 lie on the face of the base 6 not held in the seal.

(10) The windows in question are often of slightly curved form, and it is possible for the bases 6 not to be positioned in the seal 10 rigorously in line with the part of the lug that faces them. The presence of two clips 7 makes it possible to compensate for certain positioning discrepancies. The log 4, which has a form that globally complements the space existing between the two arms of the clips 7, advantageously does not necessarily fill said space completely. The space in question is preferably slightly greater in volume than the end of the lug 4. To prevent this clearance being detrimental to the holding of the trim in position, a guide finger, which principally makes it possible to guide the lug 4 of the trim toward the clips, is provided. This guide finger may be arranged between the two clips 7. This wedge component advances slightly relative to the bottom of the space between the clips such that the tip of the lug rests on the bottom of this wedge component, holding the hips of the lug 4 against the arms of the clips 7, utilizing the relative elasticity of these clips.
