Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door weather strip provided with a molding portion that ensures positioning of a vehicle door on a corner sash.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. When assembling the mold forming portion 31 of the weather strip 30 to the corner portion 21 at the inner peripheral edge of the door 20, in order to facilitate the positioning and ensure the shape retention, FIG.
As shown in, the insert member 32 was embedded in the back surface of the die-molded portion 31.

However, the conventional molding portion 31 in which the insert member 32 is embedded in the back surface is insufficient for reliable and easy positioning and shape retention, and requires considerable skill, and the door 20 is repeatedly used. There is a problem that the vehicle rear side is displaced during opening and closing.

[0004]

The problem to be solved by the invention is that the conventional mold forming part 31 in which the insert member 32 is embedded in the back surface has difficulty in positioning and shape retention, and is considerably assembled. The present invention solves the above-mentioned problems because it requires a skill and also causes a shift to the rear side of the vehicle while the door 20 is repeatedly opened and closed. The present invention solves the above-mentioned problems. It is intended to provide a door weather strip that ensures the above.

[0005]

A description will be given with reference to FIGS. 1 and 3 to 5. A door weather strip 40 according to the present invention is a door weather strip 40 arranged at a corner portion 21 of a door 20 of an automobile, and includes an inner plate portion 51 for sandwiching a base portion 43 having a core extraction slit 44 from inside and outside, and a sash. An outer plate portion 52 having a shape matching 22
The insert member 50 having a substantially "engineered" cross section and an "L" shape as a whole formed integrally with the central wall 53 passing through the center core extraction slit 44 is attached to the mold forming part 41, and the insert is inserted. The door weather strip 40 is characterized in that it is provided with a mold forming portion 41 in which a center lead-out slit 44 adjacent to the member 50 is adhered with an adhesive 55 or the like.

According to the present invention, since the outer plate portion 52 of the insert member 50 is configured to be securely fitted and held on the sash 22, the positioning at the time of assembly is surely performed, and the mold forming portion 41 of the weather strip 40 is ensured. No special skill is required for the assembly, and the feeling is improved accordingly.
Since the outer plate portion 52 of the insert member 50 is securely fitted and held on the sash 22, even if the door 20 is repeatedly opened and closed,
The mold forming part 41 does not shift to the rear side of the vehicle.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION To explain an embodiment of the present invention, 20 is a door, 22 is a sash, 41 is a mold forming part, and a base part 43 fitted to the sash 22 and a base part 43 thereof are provided. The hollow seal portion 45 is integrated. 44
Is a core extraction slit formed on the back surface of the base portion 43.

Explaining the insert member 50,
Reference numeral 51 denotes an inner plate portion to be brought into contact with the inner surface of the base portion 43,
It is inserted from the center core withdrawing slit 44 of the base portion 43 of the mold forming portion 41. Reference numeral 52 denotes an outer plate portion that is fitted to the sash 22 and covers the outer surface of the base portion 43, and is connected to the inner plate portion 51 via a central wall 53.

The operation will be described. When the inner plate portion 51 is inserted from the center core withdrawing slit 44 of the base portion 43 of the mold forming portion 41 and brought into contact with the inner surface of the base portion 43, the other of the central wall 53 inserted through the center core withdrawing slit 44 The outer plate portion 52 joined to the end remains outside. Further, by fitting the base portion 43 to the outer plate portion 52 and then fitting the outer plate portion 52 to the sash 22,
The mold forming part 41 is assembled to the door 20.

[0010]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the positioning at the time of assembling is surely performed, and no special skill is required for assembling the weatherstrip type molding portion, so that the feeling is improved. To do. Moreover, since the outer plate portion 52 of the insert member 50 is securely held by the sash 22, even if the door 20 is repeatedly opened and closed, the mold forming portion 41 does not shift to the vehicle rear side.
