本発明は自動車用ウエザストリツプ、特に室内
から見える面を装飾用の布で被覆したウエザスト
リツプに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a weather strip for automobiles, and particularly to a weather strip whose surface visible from the interior is covered with a decorative cloth.

リツプが用いられるようになつてきた。
In order to improve the interior design of automobiles, so-called cloth-wrapped weather strips have come to be used, in which the surface visible from the interior is covered with cloth in a color that matches the interior color. Ta.

用いられており、布で被覆する場合には被覆すべ
き面にウレタン系ゴム等の接着剤を塗布し、これ
に布を貼着している。 Recently, weather strips made of ethylene propylene rubber (EPDM) have generally been used, and when covering with cloth, an adhesive such as urethane rubber is applied to the surface to be covered, and then the cloth is pasted. I'm wearing it.
しかしながら、接着剤塗布作業が必要である上

ザストリツプのEPDMが極性基を有しないため、
接着剤とEPDMが結合しないからである。
However, in addition to requiring an adhesive application operation, it is complicated to position the cloth onto the adhesive before the adhesive hardens. Furthermore, when applying the adhesive, the applied surface of the weather strip is roughened using a buff or the like, but the adhesion of the adhesive to the weather strip is not always good. This is because the EPDM in the weather strip does not have polar groups.
This is because the adhesive and EPDM do not bond.
そこで本発明は、布が強固に接着され、かつ布

とするものである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a cloth-wrapped weather strip to which cloth is firmly adhered and which can be easily coated with cloth, thereby solving the problems of the prior art.

The weather strip of the present invention has a U-shaped cross-sectional mounting base made of EPDM, and a decorative cloth is coated with a backing of polyolefin resin, such as polyethylene (PE) or polypropylene (PP), and then heated through the backing. It is welded.

When polyolefin-based resin is heat-welded to EPDM, which is also a polyolefin-based resin, in a heat-softened state, it bonds firmly to EPDM.
The decorative fabric is bonded to the weatherstrip without peeling. Furthermore, there is no need to apply adhesive to the weather strip, and the cloth can be easily positioned, improving workability.

Made of EPDM solid rubber, prosthetic core material 3
is buried there. The hollow seal portion 2 is made of EPDM sponge rubber. A lip 4 protrudes from the inner surface of the mounting base 1 in opposite directions, and the weather strip W is mounted along the door opening by clamping a flange (not shown) formed at the door opening. The hollow seal part 2 is located on the outside of the room and comes into contact with the outer peripheral edge of the door 7 when the door is closed, and the outer surface of the mounting base 1 except for the part forming the hollow seal part is visible from inside the room.

形に曲げ加工する。 In order to manufacture this weather strip W, a molded body having a hollow seal part 2 of EPDM sponge rubber at one end of the mounting base of a flat EPDM solid rubber in which a core material 3 is embedded is extruded, and after extrusion,
The flat mounting base is bent into a U-shaped cross section as shown in FIG.
