1. A method for forming a combination door and window channel seal comprising:
- extruding thermoplastic elastomers of at least two different durometer values to form a door and window channel seal in a one-piece generally U-shaped configuration so that a corner of a window channel section of the seal has an elastic strip of increased flexibility disposed between substantially rigid strips of a material having less elasticity than the elastic strip, the window channel section selected to operably receive a resilient window engaging sealing insert, and the door and the window channel seal including a second generally U-shaped flange engaging portion.

Abstract
A combination door and window channel seal for sealing between a motor vehicle door frame and movable window glass panel and a method for forming the same are described. The channel seal is formed from thermoplastic elastomers of at least two different durometer values and has an elastic joint in a window run channel portion of the seal.

4. A method for forming a combination door and window channel seal for a motor vehicle, the method comprising:
molding thermoplastic elastomers of at least two different durometer values to form a door and window channel seal in a one-piece generally U-shaped configuration so that a corner of a window channel section of the seal has an elastic strip of increased flexibility disposed between adjacent strips, the elastic strip of a more elastic material than the adjacent strips, the window channel section adapted to receive a resilient window engaging sealing insert to contact a glass panel. - View Dependent Claims (5, 6, 7)
- 8. A method for forming a combination door and window channel seal for a motor vehicle, the method comprising extruding thermoplastic elastomers of at least two different durometer values, one of the thermoplastic elastomers being of a greater elasticity, to form a door and window channel seal in a one-piece generally U-shape configuration having an elastic joint strip of the greater elasticity thermoplastic elastomer intermediate a pair of strips formed of thermoplastic elastomer of less elasticity, the generally U-shape configuration of the door and window channel seal adapted to receive and retain a resilient window engaging sealing insert.
