Sealing member

摘要

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.

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.
