Sealing assembly for a vehicle and method of manufacturing a sealing assembly
First Claim
1. A sealing assembly for a vehicle having a fixed window and a panel, said sealing assembly comprising:
- a sealing body extruded from an elastomeric material formed from an ethylene propylene diene monomer (EPDM) with said sealing body having a base and first and second legs spaced from one another extending from said base with said base and said first and second legs defining an interior surface and a first channel for receiving the panel within said first channel, and said base and said first and second legs further defining an exterior surface opposite said interior surface with said sealing body defining an overmold region opposite said first channel extending along a portion of said exterior surface of said sealing body;
a bonding layer of a first thermoplastic vulcanizate (TPV) co-extruded onto said overmold region of said sealing body; and
a molded layer of a second thermoplastic vulcanizate (TPV) molded onto said bonding layer with said second TPV of said molding layer bonded to said first TPV of said bonding layer to attach said molded layer to said sealing body, with said molded layer remaining spaced from said sealing body by said bonding layer along said overmold region and defining a second channel for receiving the fixed window of the vehicle within said second channel.

Abstract
A sealing assembly for a vehicle comprises a sealing body extruded from an elastomeric material formed from an ethylene propylene diene monomer and having a base and first and second legs spaced from one another extending from the base. The base and the legs define an interior surface and a first channel for receiving a panel, and further define an exterior surface opposite the interior surface. The sealing body defines an overmold region opposite the first channel extending along a portion of the exterior surface of the sealing body. The sealing assembly further comprises a bonding layer of a first thermoplastic vulcanizate co-extruded onto the overmold region of the sealing body, and a molded layer of a second thermoplastic vulcanizate molded onto the bonding layer with the molded layer defining a second channel for receiving a fixed window of the vehicle. Also disclosed is a method for manufacturing a sealing assembly.

15. A method of manufacturing a sealing assembly for a vehicle having a fixed window and a panel, said method comprising the steps of:
-
extruding an elastomeric material formed from an ethylene propylene diene monomer (EPDM) to form a sealing body having a base and first and second legs spaced from one another extending from the base with the base and the first and second legs defining an interior surface and a first channel for receiving the panel within the first channel, and the base and the first and second legs further defining an exterior surface opposite the interior surface with the sealing body defining an overmold region opposite the first channel extending along a portion of the exterior surface of the sealing body; co-extruding a first thermoplastic vulcanizate (TPV) onto the overmold region of the sealing body to form a bonding layer on the overmold region; and molding a second thermoplastic vulcanizate (TPV) onto the bonding layer to form a molded layer with the molded layer defining a second channel for receiving the fixed window of the vehicle within the second channel. - View Dependent Claims (16, 17, 18, 19, 20, 21)
