#This application is based upon, claims the benefit of priority of, and incorporates by reference Japanese Patent Application No. 2005-156991 filed on May 30, 2005.

#1. Field of the Invention

#The present invention relates to a glass run for a vehicle door and a structure of fixing the glass run to the vehicle door. The glass run provides a good seal and a good appearance for the vehicle door.

Brief description of the drawings5 figures

#The accompanying figures, in which like reference numerals refer to identical or functionally similar elements throughout the separate views and which, together with the detailed description below, are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present invention.

#FIG. 1 is a front view of a vehicle door;

#FIG. 2 is a cross sectional view along line II-II of FIG. 1;

Detailed description1,142 words

#Referring to FIG. 1, a door D for a vehicle includes a glass run 1 that seals a peripheral portion of a door glass G. As shown in FIG. 2, a garnish 3 for decorating a vehicle interior is attached along an inside portion of a doorframe 2 (an inner panel 51). An outside edge of the garnish 3 is curved along a corner part of the doorframe 2 in FIG. 4.

#The glass run 1 is made of EPDM (ethylene-propylene-diene-copolymer) solid rubber. The glass run 1 can be made of any other rubber materials or thermoplastic elastomers. As shown in FIG. 1, the glass run 1 includes an upper extruded portion 10, front and rear side vertical extruded portions 11, 12 and molded corner portions 13, 14 that connect each end of the upper extruded portion 10 to one end of each of the vertical extruded portions 11, 12. The upper extruded portion 10 and the vertical extruded portions 11, 12 have an elongated straight body and are formed by an extruder (not shown). The upper extruded portion 10 and the vertical extruded portion 11 are set in a mold apparatus (not shown) at a predetermined angle. Then the molded corner portion 13 is formed by the mold apparatus. Thus, the molded corner portion 13 is continuously formed with the upper extruded portion 10 and the vertical extruded portion 11. Identically, another mold apparatus can form the molded corner portion 14 in the same manner. In the present embodiment, the upper extruded portion 10 is a first extruded portion, and the vertical extruded portions 11 is a second extruded portion.

#As shown in FIGS. 2 and 3, the glass run 1 is fixed to a channel 15, which is formed at an inside of the doorframe 2 of a door by an inner panel 51 and a molding member 52. The glass run 1 includes a body portion 20 and a couple of seal lips 21, 22. The body portion 20 has a flat base 16 and a couple of side walls, which are an inside wall portion 17 and an outside wall portion 18. The inside wall portion 17 and the outside wall portion 18 are substantially extended in parallel from the base 16. Therefore, the body portion 20 is U-shaped in cross-section. The seal lips 21, 22 are inwardly extended into the body portion 20 from each end of the inside wall portion 17 and the outside wall portion 18. The seal lips 21, 22 seal a peripheral portion of the door glass G. Also, the seal lips 21, 22 can seal the door glass G while the door glass G moves up and down.
