Abstract

PURPOSE: To provide a body side weather strip which causes no creases when it is installed on the corner part, has good appearance, and is hard to wear away even if it rubs against a person's clothes when he gets into a car interior. CONSTITUTION: A body side weather strip is formed by integrally connecting a hollow seal part 32 formed by sponge rubber to one side surface of a U-shaped trim 31 formed by solid rubber, and fitted to a flange of a body panel. In the body side weather strip, a slightly foam sponge rubber coat 34 with the specific gravity of 0.9-1.1 is formed on the surface of a sponge rubber layer 33 of the hollow seal part 32.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body side weather strip mounted on a flange of a body panel, which has improved wear resistance and appearance.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. In the figure, a symbol is used in which one of the median lines descending from the apex angle of the isosceles triangle is painted, and the painted side represents a molded part, and the unpainted side represents an extruded part. . Conventionally,
As a body side weather strip to be attached to a flange of a body panel, a solid rubber coating 14 is formed on the surface of a sponge rubber layer 13 on one side surface of a U-shaped trim 11 made of solid rubber, as shown in FIGS. A hollow seal portion 12 integrally joined is used. The reason for forming the solid rubber coating 14 is to prevent the surface of the hollow seal portion 12 from rubbing against the clothes and wearing when a person gets into the room. Reference numeral 15 is a decorative lip and 16 is a core metal.

When importance is attached to color matching with interior parts, as shown in FIGS. 1 and 3, a U-shaped trim 21 made of synthetic resin and a sponge rubber layer 23 have a solid rubber coating on the surface thereof. A hollow seal portion 22 having 24 formed therein is extruded as a separate body and is bonded with an adhesive S, which is used. The reason for forming the solid rubber coating 24 is as described above. 25 is a decorative lip, and 26
Is a cored bar.

However, in the above-mentioned conventional body side weather strips 10 and 20, the solid rubber is inferior to the sponge rubber in following the deformation, so that the corner portion,
Particularly, the corner portion C above the center pillar 50 shown in FIG.
When attached to the solid rubber coating 14, the solid rubber coating 14 is not uniformly deformed and wrinkles occur, resulting in a poor appearance. As a countermeasure, a pad is inserted in the corner portion of the hollow seal portion 12, but it is still difficult to say that this is sufficient.

[0005]

The problem to be solved is that the above-mentioned conventional body side weather strip 1 is used.
Nos. 0 and 20 did not deform uniformly in the solid rubber coatings 14 and 24, especially when they were attached to the upper corners of the center pillar 50, and wrinkles were generated even when the pad was inserted into the corners of the hollow seal portion 12. The present invention provides a body side weather strip that solves the above problems, has wear resistance, and is excellent in the appearance of the corners because of its poor appearance.

[0006]

A description will be given with reference to FIGS. 1, 4, and 5. FIG. A first aspect of the present invention is a body side weather strip in which a hollow seal portion 32 made of sponge rubber is integrally joined to one side surface of a U-shaped trim 31 made of solid rubber, which is attached to a flange of a body panel. Then, a fine foam sponge rubber coating 34 having a specific gravity of 0.9 to 1.1 is formed on the surface of the sponge rubber layer 33 of the hollow seal portion 32.

A second aspect of the invention is a U-shaped trim 41 made of synthetic resin, which is attached to a flange of a body panel.
A body side weather strip formed by preliminarily molding hollow seal portions 42 made of rubber and sponge rubber, and adhering them together, and having a specific gravity of 0.9 to 1.1 on the surface of the sponge rubber layer 43 of the hollow seal portion 42. A fine foam sponge rubber coating 44 is formed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first invention will be described with reference to FIGS. 1 and 4. Reference numeral 30 is a body side weather strip of the first invention, and 31 is a U-shape made of solid rubber to be attached to a flange of a body panel. -Shaped trim 32 is a hollow seal portion integrally connected to one side surface of the U-shaped trim 31, and a fine foam sponge rubber coating 34 having a specific gravity of 0.9 to 1.1 is formed on the surface of the sponge rubber layer 33. I am doing it. Reference numeral 35 is a lip protruding from the other side surface of the U-shaped trim 31, and reference numeral 36 is a core metal.

FIG. 1 shows the second embodiment of the invention.
Referring to FIG. 5, reference numeral 40 is a body side weather strip of the second invention, 41 is a U-shaped trim made of synthetic resin to be attached to a flange of a body panel, and 42.
Is a hollow seal portion, and a fine foam sponge rubber coating 44 having a specific gravity of 0.9 to 1.1 is formed on the surface of the sponge rubber layer. Then, the U-shaped trim 41 and the hollow seal portion 4
Reference numeral 2 is attached by an adhesive S to be integrated. In addition,
Reference numeral 45 is a lip projecting from the other side surface of the U-shaped trim 41, and 46 is a cored bar.

[0010]

Table 1 shows the results of comparison of the appearance, the door closing property and the wear resistance of the example of the present invention and two comparative examples.

[0011]

[Table 1]

As is clear from Table 1, the body side weather strip of the present invention has a hollow seal portion 3
Specific gravity 0.9 on the surface of 2, 42 sponge rubber layers 33, 43
Since the micro foam sponge rubber coatings 34, 44 of 1.1 are formed, the followability to bending is excellent, and the micro foam sponge rubber coatings 34, 44 are uniform even when bent at the corner C of the upper part of the center pillar 50. It has a good appearance without being wrinkled and has excellent wear resistance compared to sponge rubber. Even if the rubber coatings 34, 44 and the clothes rub against each other, they are not easily worn.

[0013]

Since the present invention is configured as described above,
When bent at the corner C of the upper part of the center pillar 50, it does not cause wrinkles and has an excellent appearance.
Even if a person rubs against clothes when getting into the room, it has an effect of being less likely to wear.
