Abstract

An over-moulded frame for encapsulating motor vehicle windows in which in a plastics element over-moulded onto the edge of a window there is embedded a metal stiffening and support structure for the window edge and for a seal gasket for adjacent windows.

Claims

1. An over-moulded frame for encapsulating vehicle windows, consisting of a plastics element over-moulded onto the edge of a vehicle window in such a manner as the embrace said edge by having an essentially U-shaped cross-section, characterized in that said plastics element comprises embedded in its interior a metal stiffening structure having a substantially U-shaped main section arranged in the same direction as said cross-section of said plastics element, from said main section there extending at least one appendix able to securely receive and support a gasket arranged to provide a seal against an adjacent window.

2. A frame as claimed in claim 1, characterized in that said metal stiffening structure is provided with a plurality of gripping teeth situated within said main section and in contact with said edge of said window.

3. A frame as claimed in claim 1, characterized in that said plastics element has a jutting curved profile able to collect and dispose of water.

4. A frame as claimed in claim 1, characterized in that said gasket arranged to provide a seal against an adjacent window is an extruded gasket having a sealing bulb and carrying laterally a body provided with a seat to receives and engage said at least one appendix extending from said metal stiffening structure.

5. A frame as claimed in claim 4, characterized in that said bulb of said extruded gasket has a substantially annular hollow cross section.

6. A frame as claimed in claim 4, characterized in that said body positioned laterally to and fixed to said sealing bulb is provided with a seat of U cross-section.

7. A frame as claimed in claim 4, characterized in that said body positioned laterally to said sealing bulb is provided with a contact tooth close to an end portion of said plastics element.

8. A frame as claimed in claim 1, characterized in that said at least one appendix is a continuous strip element formed integrally with said metal stiffening structure.

9. A frame as claimed in claim 1, characterized in that said at least one appendix is arranged perpendicular to said main U-shaped section in proximity to one end of its arms.
