Trim molding for a motor vehicle window panel
A motor vehicle window panel has a peripheral trim molding formed by an extruded body of plastics material, and the body includes a mounting flange and a vehicle body sealing flange integrally connected by an intermediate connecting portion. The mounting flange carries a pressure sensitive contact adhesive tape which bonds to an inner surface of the window panel, and the intermediate connecting portion has an internal stabilizing strip and a durometer greater than the durometer of the mounting flange and of the sealing flange. The molding may be supported within a fixture for receiving the window panel or may carry a tear-off locating flange which slides against an edge surface of the window panel to locate the molding on the panel. The mounting flange may carry a spacer rib, and the mounting flange, sealing flange and connecting portion are located inwardly of the inner surface of the window panel.
1. A trim molding in combination with a motor vehicle window panel having an inner surface and a parallel outer surface connected by a peripheral edge surface, said molding comprising
an elongated extruded flexible body of plastics material and including a mounting flange connected to a sealing flange by an intermediate connecting portion with said mounting flange and said sealing flange projecting in opposite directions from said intermediate connecting portion,
a layer of adhesive on said mounting flange and bonding said mounting flange to said inner surface of said window panel,
said sealing flange projecting laterally outwardly from said intermediate connecting portion with said intermediate connecting portion having a substantially higher durometer than a durometer of said sealing flange and a durometer of said mounting flange,
a non-stretchable and flexible metal stabilizing strip extending longitudinally within said intermediate connecting portion and disposed entirely inwardly from said inner surface of said window panel,
said stabilizing strip having a substantially uniform thickness and a width substantially greater than its thickness and positioned within said intermediate connecting portion with said width of said strip perpendicular to said inner surface of said window panel,
said body including said mounting flange, said intermediate connecting portion and said stabilizing strip disposed entirely inwardly of a plane defined by said inner surface of said window panel with said intermediate connecting portion and said metal stabilizing strip substantially aligned with said peripheral edge surface of said window panel, and
said intermediate connecting portion with said higher durometer cooperating with said stabilizing strip to provide for longitudinal stretching of said sealing flange in response to curving said molding around a curved corner edge surface of said window panel without stretching said intermediate connecting portion and without substantially distorting said trim molding.
2. A trim molding as defined in claim 1 wherein said intermediate connecting portion has an outer edge surface substantially flush with said edge surface of said window panel.
3. A trim molding as defined in claim 2 and including a longitudinally extending locating flange projecting from said outer edge surface of said intermediate connecting portion and adapted to slide on said edge surface of said window panel in a direction perpendicular to said inner surface of said window panel for locating said trim molding on said window panel, and said outer edge surface of said intermediate connecting portion and said locating flange define therebetween a weakened tear zone to provide for quickly removing said locating flange after said layer of adhesive contacts said inner surface of said window panel.
4. A trim molding as defined in claim 1 wherein said intermediate connecting portion is substantially rectangular in cross-section and has an outer edge surface substantially flush with said edge surface of said window panel, and said stabilizing strip is disposed within a center portion of said intermediate connecting portion.
5. A trim molding as defined in claim 1 wherein said mounting flange and said sealing flange have substantially the same durometer.
