Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a sealing member which is attached to a door sash of an automobile door and seals an edge of a window glass, and more particularly to a sealing member integrally provided with a molding portion for decorating the door sash.

[0002]

2. Description of the Related Art For example, in Japanese Utility Model Laid-Open No. 62-95928, as shown in FIG. 10, a glass run portion 34 mounted on the inner side of the door sash 32 to seal the edge of a window glass 33, A seal member 31 for a door is formed by integrally molding a molding portion 35 that covers the outer side surface of the door sash 32 on the vehicle outer side. The seal member 31 has a welt portion 36 having a U-shaped cross section that is fitted to the door sash 32, and a core metal 37 is embedded so as to surround the welt portion 36. In this example, the hollow main seal 38 that seals between the door opening edge on the vehicle body side
Also, the hollow sub-seal 39 constituting the double seal is also integrated.

[0003]

In the above structure, the glass run portion 34 and the molding portion 35 are integrated, but the number of parts can be reduced.
On the other hand, the terminal processing at the door corner is troublesome. For example, if the illustrated sealing member 31 is arranged along the upper edge of the front door, a glass run having a different cross-sectional shape is used for the door sash at the rear edge of the front door, so that the corner portion at the upper rear edge of the front door is used. Both will be connected by molding. At this time, since it is desirable in appearance that the molding portion 35 be continuously provided over the front and rear doors, the molding portion 35 is separated from the glass run portion 34,
It is necessary to extend only the molding portion 35 to the rear end of the door sash.

However, the above-mentioned conventional seal member 31 is used.
In this case, the molding portion 35 and the grass run portion 34 are integrally formed in an inseparable form, and when they are separated by a cutter, it is necessary to cut them so as to cross the welt portion 36 having the cored bar 37. Therefore, there are problems that the cutting work is very difficult, the molding 35 is deformed, and the cut surface becomes very dirty. Moreover, there is a problem that the cut cored bar 37 is exposed and rusts.

[0005]

According to the present invention, a molding portion for covering an outer surface of a side wall of a door sash on the vehicle outer side and a glass run mounted on the door inner peripheral side of the door sash are integrally formed by extrusion molding. In a sealing member for an automobile door, an end portion of the molding portion on the outer peripheral side of the door is curved and formed in a U shape so as to engage with an end portion of the side wall, and the end portion is similarly formed inside the molding portion. Is embedded with a U-shaped core,
In addition, an edge of the molding portion on the inner peripheral side of the door is formed to extend longer than an edge of the side wall, and the rear surface of the portion projecting from the side wall and the leg portion on the vehicle outer side of the grass run are connected through a thin portion. It is characterized by having done.

[0006]

In the above structure, since the molding portion to be extended along the door sash surface at the corner portion of the door and the grass run cut at a predetermined position for molding are simply connected by the thin portion, Both can be easily separated from each other in the terminal processing of the corner section. Further, the shape of the extended molding portion is maintained by the cored bar embedded therein.
