Seal for a lowerable window pane of a vehicle door window
A seal between a frame part of a vehicle door window and the upper edge of a lowerable window pane of the vehicle door window. A seal profiled element of plastic is provided, which is slid onto a flange protruding upward from the frame part of the vehicle window and/or which is connected to a tube-shaped seal section for forming a seal between the frame part and a border surface of a door opening in a vehicle body.
1. A seal between a frame part of a vehicle door window and the upper periphery of a lowerable window pane of the vehicle door window, comprising a seal profile made of various thermoplastic materials plug-fitted by a U-shaped fastening portion onto a flange that projects upward from the frame part of the vehicle door window, and connected to a tubular seal portion composed of a thermoplastic material for forming a seal between the frame part and a peripheral face of a door opening in a vehicle body, wherein the tubular seal portion has a wall with a first end connected to an internal U-leg of the U-shaped fastening portion in a materially integral manner and a second end where a latched form-fitting connection is established.
2. The seal according to claim 1 , wherein the seal profile is plug-fitted onto the flange by a U-shaped fastening portion.
3. The seal according to claim 2 , wherein the U-shaped fastening portion has an external U-leg that forms an internal U-leg of a U-shaped groove portion that forms a receptacle groove for the upper periphery of the window pane.
4. The seal according to claim 1 , wherein the seal profile has a metal insert that delimits thermal expansion.
5. The seal according to claim 3 , further having a seal portion that extends upward from an upper end of an external U-profiled leg of the U-shaped groove portion.
6. The seal according to claim 5 , wherein the seal portion is a seal lip.
7. The seal according to claim 3 , wherein the external leg of the fastening portion that forms the internal U-profiled leg of the groove portion has an extension downward in terms of length.
8. The seal according to claim 7 , wherein a free end of the extension is connected to a trim strip portion that engages below the frame part.
9. The seal according to claim 7 , wherein the extension has an installation for connecting to the frame part.
10. The seal according to claim 9 , wherein the installation for connecting to the frame part is a detent protrusion.
11. The seal according to claim 9 , wherein the extension has seal lips that seal the window pane, the seal lips being separate from the installation for connecting.
12. The seal according to claim 5 , wherein the external U-leg of the groove portion has a trim strip portion.
13. The seal according to claim 1 , wherein the fastening portion is composed of a single thermoplastic material, and at least in parts the groove portion is composed of the thermoplastic material from which the fastening portion is composed.
14. The seal according to claim 1 , wherein the seal profile is formed by multiple extrusion and subsequent processing for bending the extruded product.
