Abstract

A glass roof assembly for a motor vehicle has a glass roof ( 30 ). A fastening element ( 32 ) made of plastic is connected fixedly on an edge region of the glass roof ( 30 ), and a body structure ( 12 ) of the vehicle has a fastening flange ( 20 ) for fastening the glass roof ( 30 ). The glass roof ( 30 ) is connected fixedly to the fastening flange ( 20 ) via the fastening element ( 32 ). A reinforcing element ( 34 ) made of plastic is integrated into the fastening element ( 32 ) and extends along the fastening flange ( 32 ) in the longitudinal direction of the vehicle and/or in the transverse direction of the vehicle. The reinforcing element ( 34 ) has, at least in sections, higher strength than the fastening element ( 32 ).

Claims (19)

1 . A glass roof assembly for a motor vehicle having a body structure that has a fastening flange, comprising a glass roof having an edge region; a fastening element made of plastic and connected fixedly to the edge region of the glass roof; and a reinforcing element made of plastic and integrated into the fastening element such that the reinforcing element, at least in sections, is fully surrounded above and below by the fastening element, the reinforcing element extending along the fastening element in a longitudinal direction of the vehicle and/or in a transverse direction of the vehicle, at least sections of the reinforcing element having a higher strength than the fastening element, wherein the glass roof is connected fixedly to the fastening flange via the fastening element.

2 . The glass roof assembly of claim 1 , wherein the motor vehicle further comprises a roof support system with bracing, and wherein the reinforcing element immediately abuts the fastening flange and is fixedly connected to the fastening flange adjacent the bracing of the roof support system.

3 . The glass roof assembly of claim 1 , wherein a gap is defined between the glass roof and the body structure, and the fastening element comprises a cover lip that covers the gap between the glass roof and the body structure.

4 . The glass roof assembly of claim 3 , wherein a roof support system has a fixing element that is inserted through the gap between the glass roof and the body structure and fastened on the body structure.

5 . The glass roof assembly of claim 1 , wherein the fastening element is produced by over-molding the glass roof.

6 . The glass roof assembly of claim 1 , wherein the reinforcing element is embedded in the fastening element.

7 . The glass roof assembly of claim 1 , wherein the fastening element is glued to the glass roof.

8 . The glass roof assembly of claim 1 , wherein the fastening element is made from a plastic foam.

9 . An assembly having the glass roof assembly of claim 1 and a roof support system, the roof support system being braced on the glass roof.

10 . The glass roof assembly of claim 1 , wherein the fastening element is made from polyurethane, and the reinforcing element is made from polyamide.

11 . The glass roof assembly of claim 1 , the fastening element is glued to and/or screwed to the fastening flange of the body structure.

12 . The glass roof assembly of claim 1 , wherein the reinforcing element extends along an entire length of the fastening element.

13 . A glass roof assembly for a motor vehicle having a body structure that has a fastening flange, comprising:

a glass roof having an edge region;

a fastening element made of plastic and connected fixedly to the edge region of the glass roof; and

a reinforcing element made of plastic and integrated into the fastening element, the reinforcing element extending along the fastening element in a longitudinal direction of the vehicle and/or in a transverse direction of the vehicle, at least sections of the reinforcing element having a higher strength than the fastening element, wherein the glass roof is connected fixedly to the fastening flange via the fastening element,

wherein the motor vehicle further comprises a roof support system,

wherein a gap is defined between the glass roof and the body structure, and the fastening element comprises a cover lip that covers the gap between the glass roof and the body structure, and

wherein the roof support system has a fixing element that is inserted through the gap between the glass roof and the body structure and fastened on the body structure.
