[Related technologies]
A glass weather strip for a front door D of an automobile basically includes a glass run 14 having a substantially U-shaped planar shape for holding the elevating glass 12, and a glass weather strip 16 disposed on the door belt line (see FIG. 1).
[0004]
In general, the glass run 14 is cut out of extruded products having the same or different basic cross section, and the rear end of the roof portion 20 of the glass run 14 and the post-glass run pillar portion 24 are connected to each other by a molding corner portion 26. Form. Further, the front / rear lower mold parts 32 and 34 are usually molded at the position of the door belt line 30 of the glass run front pillar part / rear pillar part 22, 24, and the front / rear lower mold part 32. , 34 are butt-connected to the front and rear terminals of the WS outer 36 which is the glass weather strip 16. Although not shown, the WS inner was also butt connected. (See JP 7-257181 A, etc.)
Here, the connecting line L between the rear lower mold part 34 and the glass run post pillar part 24 was usually a position several cm higher than the drab belt line position. The reason is as follows (see FIG. 2).
[0005]
In response to a request for a flash surface in the door (the distance between the glass surface and the door panel surface is made as small as possible), the inner panel 52, the outer panel 54, and the middle panel 56, and the wind frame F portion is also the door. It is often done in one piece with the body. And in the mounting step part 60 formed in the vehicle outside of the mounting flange part 58 which attaches the glass run rear pillar part 24 formed of the outer panel 54 and the middle panel 56, the roof 20 side is as narrow as possible. desirable. On the other hand, the lower side of the belt line 30 accommodates the door key mechanism and the glass lifting mechanism, and has a shape that bulges outward from the strength point of view, so the mounting step 60 of the outer panel 54 at the belt line 30 position is wide. Therefore, it is necessary to change the glass run section correspondingly.
[0006]
[Problems to be solved by the invention]
However, the connection line L between the lower rear mold part 34 and the glass run post pillar part 24 is problematic in terms of design. Further, the mold part 34 and the glass run 24 that is an extruded product are molded. Even if the same kind of material is used as the material to be used, a difference in color and luster tends to occur between injection and extrusion, and the weather strip is not integrated, which is undesirable from the viewpoint of design.
[0007]
In view of the above, the present invention has a structure in which the glass lamp pillar part and the WS outer are connected via the lower mold part, and the connection of the weather strip in which the connection line between the mold part and the glass lamp pillar part does not appear.
