    Description

    [0028] The invention is explained in greater detail below with reference to the drawing by means of exemplary embodiments of edge profiles according to the invention and methods for producing such an edge profile. In the drawing:

    [0029] FIG. 1 shows an isometric view of a vehicle roof with a glass pane which, adjoining a windshield, covers a surface area of the vehicle roof;

    [0030] FIG. 2 shows a longitudinal sectional view of a vehicle frame of the vehicle roof with the glass pane attached thereto and an edge profile, which is attached to the front pane edge and forms an edge protection strip;

    [0031] FIG. 3 shows a plan view of an edge profile with a spacing web integrally formed on a base leg of the edge profile in order to form a distance piece;

    [0032] FIG. 4 shows a plan view of an edge profile with a plurality of distance pieces arranged at a distance from one another over its length;

    [0033] FIG. 5 shows a sectional view of another embodiment of an edge profile with a distance piece; and

    [0034] FIG. 6 shows a side view of an edge profile with a plurality of distance pieces integrally formed thereon.

    [0035] A vehicle roof 1 (see FIG. 1) of a vehicle 2, such as a passenger car, has a glass pane 3, the front pane edge 4 of which is adjacent to a windshield 5 and which is arranged on both sides on lateral roof longitudinal beams 6. Such a glass pane 3 is, for example, part of a roof module or FTM (fixed transparent module). The glass pane 3 is expediently fastened to the vehicle roof 1 by means of adhesive bonding, e.g. by means of a bead of adhesive 7. At least the front pane edge 4 of the glass pane 3 is provided with an edge profile 8 (FIG. 2), which forms an edge protection profile. The edge profile 8 is expediently formed as a deformation-resistant plastics profile. In particular, the edge profile 8 is produced by extrusion from a thermoplastic such as, for example, from ASA.

    [0036] The edge profile 8 is fastened to the glass pane 3, which is, for example, a multilayer laminated safety glass (FIG. 2). The edge profile 8 has a base leg 9, which contains a fastening or adhesive surface on its inner side 10 or inner surface facing the glass pane 3. Furthermore, the edge profile 8 has a protective leg 11, which is angled with respect to the base leg 9 and is formed substantially at right angles to the base leg 9. The edge profile 8 is fastened by means of its base leg 9 to a pane inner side or pane underside 12 of the glass pane 3 by means of an adhesive bond 13. The adhesive bond 13 is produced, for example, by means of a layer of adhesive or an adhesive tape on the fastening or adhesive surface on the inner side 10 of the base leg 9, on the one hand, and on an edge strip 14, adjoining the pane edge 4, of the pane underside 12 of the glass pane 3, on the other hand.

    [0037] The glass pane 3 is fastened or adhesively bonded to a vehicle frame 15 by means of the bead of adhesive 7. The bead of adhesive 7 extends inwardly of the edge profile 8 along the pane edge 4. The vehicle frame 15 is, for example, a roof frame of the vehicle roof or of the vehicle body or a frame of a roof module or FTM. The edge profile 8 has a plurality of distance pieces 16 (illustrated schematically in FIG. 4), which are arranged at a distance from one another along the edge profile 8. Each distance piece 16 is arranged between the base leg 9 and the vehicle frame 15 and rests by means of a bearing surface 17 against the vehicle frame 15. The distance pieces 16 define an installation position of the glass pane 3 relative to the vehicle frame 15 carrying the glass pane 3 by setting the spacing between the edge profile 8 and the vehicle frame 15.

    [0038] Preferably, the distance pieces 16 are produced as extruded plastics parts which are extruded or coextruded on the base leg 9 during the production or extrusion of the edge profile 8. The distance pieces 16 can be produced as thermoplastic parts, in the case of edge protection profiles for example, or as elastomeric parts, from EPDM for example, as in the case of sealing profiles produced therefrom. The distance pieces 16 then project downward, starting from an outer side 18 of the base leg 9, or opposite the inner side 10 of the base leg 9.

    [0039] A method according to the invention for producing such an edge profile 8 envisages that the edge profile 8 is extruded with an additional spacing web 19 (FIG. 3). The spacing web 19 is expediently integrally formed or coextruded on the underside or outer side 18 of the base leg 9 with a cross-sectional shape which corresponds to that of the distance piece 16 to be formed. The distance piece 16 is produced by removing or cutting out web material of the spacing web 19 from the spacing web 19 in a region or section between two distance pieces 16 to be formed. Two adjacent distance pieces 16 are thus separated from one another by a web cutout 20 formed during this process (see FIG. 6).

    [0040] Such a web cutout 20 can be made, in particular immediately after the extrusion of the edge profile 8 for example, by a cut with a knife or a blade, which is expediently taken along with the edge profile as it moves following the extrusion operation and, in the process, cuts out the web cutout 20, e.g. in wave form and, in particular, in sinusoidal wave form (FIG. 6).

    [0041] It is also possible to produce a respective web cutout 20 by removing the web material by means of a cut which is, for example, horizontal, or by means of horizontal punching or parallel to the base leg 9 of the edge profile 8.

    [0042] On the other hand, it is also possible to produce a respective web cutout 20 by removing the web material by means of a cut which is, for example, vertical, or by means of vertical punching or perpendicularly to the base leg 9 of the edge profile 8. FIG. 5 shows an embodiment of the edge profile 8 in which a spacing web 19 is formed as part of an extension 21 of the base leg 9, which extension is integrally formed so as to extend beyond an end face 22 on the end of the base leg 9. By means of vertical cuts, web material is cut out of the extension 21 and the spacing web 19 in order to form a respective web cutout 20 between two remaining distance pieces 16.

    [0043] On the other hand, the distance pieces 16 can also be attached to the edge profile or to the base leg 9 of the edge profile 8 as additional components and, in particular, can be adhesively bonded to the base leg 9.
