Sealing member
First Claim
1. A sealing member for a vehicle opening comprising:
- a first co-extrusion layer defining a mounting channel, a window channel, and a front face spaced from said mounting channel and said window channel, said first co-extrusion layer formed from a first elastomeric composition;
a second co-extrusion layer having a portion disposed on said front face of said first co-extrusion layer and a sealing lip disposed on said first co-extrusion layer abutting said portion and extending away from said first co-extrusion layer towards a distal end, said second co-extrusion layer formed from a second elastomeric composition which is different than said first elastomeric composition; and
a third co-extrusion layer disposed on said portion and said sealing lip of said second co-extrusion layer for covering segments of said second co-extrusion layer that are visible from an exterior of the vehicle, said third co-extrusion layer formed from a thermoplastic vulcanizate composition which is different than said first and second elastomeric compositions.

Abstract
A sealing member for a vehicle opening includes a first co-extrusion layer formed from a first elastomeric composition, a second co-extrusion layer formed from a second elastomeric composition, and a third co-extrusion layer formed from a thermoplastic vulcanizate composition. The first co-extrusion layer defines a mounting channel, a window channel, and a front face spaced from the mounting channel and the window channel. The second co-extrusion layer has a portion disposed on the front face of the first co-extrusion layer and a sealing lip disposed on the first co-extrusion layer abutting the portion and extending away from the first co-extrusion layer towards a distal end. The third co-extrusion layer is disposed on the portion and the sealing lip of the second co-extrusion layer for covering segments of the second co-extrusion layer that are visible from an exterior of the vehicle.

16. A sealing member for a vehicle opening comprising:
-
a first co-extrusion layer defining a mounting channel, a window channel, and a front face spaced from said mounting channel and said window channel, said first co-extrusion layer formed from a first elastomeric composition; a second co-extrusion layer disposed on said first co-extrusion layer and having a second sealing lip extending away from said first co-extrusion layer towards a distal end, said second co-extrusion layer formed from a second elastomeric composition which is different than said first elastomeric composition; and a third co-extrusion layer having a portion disposed on said front face of said first co-extrusion layer for covering segments of first co-extrusion layer that are visible from an exterior of the vehicle, with said third co-extrusion layer having a first sealing lip disposed on said first co-extrusion layer abutting said portion and extending away from said first co-extrusion layer towards a distal end, said first sealing lip spaced from said second sealing lip for creating a seal against the vehicle, said third co-extrusion layer formed from a thermoplastic vulcanizate composition which is different than said first and second elastomeric compositions. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method of forming a glass run sealing member comprising a first co-extrusion layer, a second co-extrusion layer, and a third co- extrusion layer, said method comprising the steps of:
-
co-extruding a first elastomeric composition to form the first co-extrusion layer, the first co-extrusion layer defining a mounting channel, a window channel, and a front face spaced from the mounting channel and the window channel; co-extruding a second elastomeric composition, which is different than the first elastomeric composition, to form the second co-extrusion layer on the first co-extrusion layer, the second co-extrusion layer having a portion disposed on the front face of the first co-extrusion layer and a sealing lip disposed on the first co-extrusion layer abutting the portion and extending away from the first co-extrusion layer towards a distal end; and co-extruding a thermoplastic vulcanizate composition, which is different than the first and second elastomeric compositions, to form the third co-extrusion layer on the second co-extrusion layer, the third co-extrusion layer disposed on the portion and the sealing lip of the second co-extrusion layer for covering segments of the second co-extrusion layer that are visible from an exterior of the vehicle. - View Dependent Claims (28, 29, 30)
