  • Patent number: 10315349
    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.

  • Patent number: 9038318
    Abstract: A seal assembly for a vehicle having a first seal and a second seal with a dual end cap disposed between the first and second seals. The dual end cap has a cover that extends beyond the first and second seal, for providing an aesthetic transition between the first and second seals. The dual end cap also has a first projection extending from the dual end cap for coupling the dual end cap to the first seal. The dual end cap also has a hold down feature extending opposite the first projection. The hold down feature engages at least a portion of the third distal end of the second seal such that the portion of the third distal end is sandwiched between the cover and the hold down feature for securing the dual end cap to the second seal.
