[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a weather strip which is mounted along an upper edge of a door outer panel of an automobile.

[0002]

2. Description of the Related Art As shown in FIG. 1, a weather strip 3 is attached to an upper edge of an outer panel of an automobile door 1 along the outer panel. As shown in FIG. 7, the weatherstrip 3 has a mounting base 31 having a substantially U-shaped cross section and sealing lips 32 and 33, and a clip assembled at a predetermined interval inside the mounting base 31. 4 is fixed to the upper edge flange 13 of the door outer panel 11. And
The seal lips 32 and 33 seal the gap between the upper edge flange 13 and the door glass 2 and wipe the outer surface of the door glass 2 when the door glass 2 moves up and down.

[0003]

When the weatherstrip 3 is assembled, the weatherstrip 3 may be entirely or partially car-mounted due to variations in the installation of door panels, deformation of the panel itself, or twisting of the weatherstrip 3. It may be assembled in a posture inclined inward (arrow C). When the weather strip 3 is tilted in this manner, a gap S is generated between the lower end edge 34 of the mounting base 31 on the vehicle outside and the outer surface of the door outer panel 11, and the appearance of the door is impaired. When the inclination is large, the seal lip 32,
33, the sliding resistance of the glass increases, and the door glass 2
At the time of lowering, there is a possibility that the seal lips 32 and 33 may be swallowed.

Accordingly, the present invention has been made to provide a weather strip mounting structure that prevents the above-described inconvenience by preventing the inward inclination of the weather strip when mounting the weather strip.

[0005]

According to the present invention, as shown in FIGS. 2 and 3 , along the upper edge of a door outer panel 11 of an automobile.
In the mounting base 31 of the weather strip 3 to be mounted by
Attach the door outer panel to the inside leg of the clip 4
A protruding portion 5 is formed to be in contact with the inner surface of the upper end of the screw 11.

In the present invention, as shown in FIG. 6, a door door is provided at the lower end of the inside of the mounting base 31 of the weather strip 3 itself.
The protruding portion 6 is formed to be in contact with the inner surface of the upper end of the outer panel 11 .

According to the present invention, at least the protrusions 5 and 6 are provided.
By forming one of them, the above problem can be solved.
It is.

[0008]

When the weather strip is assembled, the protrusions 5, 6
Is pressed against the inner surface side of the door outer panel 11 so that the weather strip 3 is tilted outward (arrow D ).
Thus, the lower edge 34 on the vehicle outside of the mounting base 31 is received by the outer surface of the door outer panel 11.
Accordingly, the lower edge 34 and the door outer panel 11 are brought into close contact with each other, and the inconvenience caused by the conventional mounting structure is eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first embodiment shown in FIGS. 2 and 3, a weather strip 3 is an extruded rubber product and has a substantially U-shaped cross section.
It has a mounting base in the shape of a letter, and seal lips 32, 33 extending obliquely upward from the side surface on the inside of the vehicle. An insert 30 is embedded in the mounting base 31.

The grip 4 is made of synthetic resin, and comprises a U-shaped part 41 fitted on the inner surface of the mounting base 31 of the weather strip 3 and a folded part 42 whose one end is inverted, and has an overall S-shape. Then, the U-shaped portion 41 is fitted into the mounting base 31, and the side portion of the mounting base 31 on the vehicle interior side is pushed into the folded portion 42, whereby the U-shaped portion 41 is mounted on the weather strip 3. Thus, the plurality of clips 4 are attached to the weather strip 3 at predetermined intervals. Each clip 4 has a protruding portion 5 formed on the inner surface of the leg end of the U-shaped portion 41 on the folded portion 42 side.

The door outer panel 11 has a gentle overhanging inclined surface 111 at the upper end, and the upper edge is the reinforcing plate 1.
2 is joined. The upper edge of the reinforcing plate 12 is a flange 13 extending upward from the outer panel 11.
The weather strip 3 is fixed by fitting each of the clips 4 incorporated therein to the flange 13 from above.

When each clip 4 is assembled to the flange 13, the projection 5 at the leg end of the clip 4 contacts the reinforcing plate 12 serving as the inner side surface of the door outer panel 11, and the weather strip 3 is inclined toward the outside of the vehicle. Since the arrow D) is given, the lower end edge 34 of the outer side of the mounting base 31 is received by the inclined surface 111 of the door outer panel 11 and is in close contact therewith. Therefore, even if the door outer panel 11 has a slight variation in installation or deformation, the gap S (FIG. 7) does not occur between the lower edge 34 and the door outer panel 11. In addition, the sliding resistance of the seal lips 32 and 33 with the door glass 2 due to the inclination of the weather strip 3 toward the inside of the vehicle and the entrapment do not occur unlike the related art.

FIGS. 4 to 6 show a second embodiment of the present invention, in which differences from the first embodiment will be mainly described.

At the rear end of the weather strip 3, a terminal portion 3A is formed by molding. The molded terminal portion 3A includes a closing portion 35 that closes the terminal cut surface of the mounting base 31 of the extrusion molding, and an extending portion 36 that extends the side surface inside the vehicle of the mounting base 31. A glass run 7 is fitted along the rear vertical line of the door frame. At the rear end of the weather strip 3, the lower seal lip 33 of the seal lips 32, 33 is cut out to avoid interference with other members of the door.

The rear end of the weather strip 3 is provided with a door lock knob or the like, so that a clip cannot be generally attached thereto. In addition, a twist is easily generated at the rear end portion of the weather strip 3, and thus the gap S (FIG. 7) is easily generated.

Therefore, in this embodiment, the protruding portion 6 is formed at the lower end of the extending portion 36 of the molded terminal portion 3A. Then
When the rear end portion of the weather strip 3 is attached to the flange 13 where the upper end of the door outer panel 11 and the upper end of the reinforcing plate 12 are joined, the terminal portion 3A has an inclination (arrow D) toward the outside of the vehicle due to the protrusion 6. The outer edge of the door outer panel 11 is in close contact with the rear end portion and the lower edge 34 of the molded terminal portion 3A on the vehicle outside. The other structure is substantially the same as that of the first embodiment, and the corresponding parts are indicated by the same reference numerals.

[0017]

As described above, according to the present invention, the projections 5 and 6 are formed on the inner leg end of the clip 4 or the lower end on the inner side of the weather strip 3, and the weather strip 3 is formed.
By assembling the weather strip 3 to the outside of the vehicle when assembling, the lower end edge 34 of the weather strip 3 on the outside of the vehicle and the outer surface of the door outer panel 11 are brought into close contact with each other,
The generation of a gap between the two can be prevented.
