ストリップである。As shown in Fig. 1, the door opening 1Vc of the automobile body is
Figure 7 shows the part of the opening trim weather strip (hereinafter simply referred to as weather strip) 5 that comes into contact with the door frame 2 of the weather strip 5, and Figure 8 shows the part of the weather strip 5 that comes in contact with the door frame 2. Installed door trim 3
The contact S with 0 is shown. The weather strip 5 consists of a base 51 and a hollow seam 52 formed along the side surface of the base 5, and is held by a flange 1 formed through the base 5 to open the door. What? 6 is a weather strip provided on the door side.
ところで、上記ドアフレーム２とドアトリム３０との境
界には第６図に示すように段部４ができて、ウェザスト
リップ５との間に三角形の隙間４０が生じ、車両内外の
遮音性を損ねる。By the way, as shown in FIG. 6, a stepped portion 4 is formed at the boundary between the door frame 2 and the door trim 30, and a triangular gap 40 is formed between the door frame 2 and the door trim 30 and the weather strip 5, impairing sound insulation inside and outside the vehicle.
そこで、第５図に示すように中空部５２には上記段部４

いるが、三角形の隙間４０を充分に小さくするに至って
いない。Therefore, as shown in FIG.
Measures have been taken to form a bulge in the corresponding portion 53, but the triangular gap 40 has not been made sufficiently small.
本発明は上記実情ＶＣ鑑みてなされたもので、遮音性が
阻害されない程度まで充分に上記隙間を小さくすること
ができるウェザストリップを提供し、もって従来の問題
点を解決することを目的とするものである。The present invention has been made in view of the above-mentioned actual situation VC, and an object of the present invention is to provide a weather strip that can sufficiently reduce the above-mentioned gap to the extent that sound insulation is not impaired, thereby solving the problems of the conventional technology. It is.

ップ５６がドアの段部４に圧接されるようＫなしたこと
を特徴と干る。As shown in FIGS. 2 and 3, in the hollow seal portion 52 of the weather strip 5, a partition wall 54 is formed to partition the inside of the weather strip 5, and a lip 56 is formed on the seal wall surface directly below the partition wall 54. 4, and the lip 56 is pressed against the step 4 of the door as shown in FIG.

追従して容易に変形し、間隙４ｏを埋める。また仕切壁
５４はそれを形成した部分に保形性を与えるから、リッ
プ５６０段部４に対する押付力が有効に作用する。When the lip 56 is pressed against the step 4, it easily deforms to follow the shape of the step 4 and fills the gap 4o. Furthermore, since the partition wall 54 provides shape retention to the portion in which it is formed, the pressing force against the step portion 4 of the lip 560 acts effectively.
第１図ないし第４図により本発明の詳細な説明する。 The present invention will be explained in detail with reference to FIGS. 1 to 4.
第１図に示すように自動車のドア開口１に沿って取付け

５２よりなる。ウェザストリップ５は一体押出成形し、
あるいは基部５１および中空シーｌｖ部５２をそれぞれ
押出成形して後、接着する。As shown in FIG. 1, a weather strip 5 installed along a door opening 1 of an automobile is made up of a base 51 having a U-shaped cross section and a hollow seal portion 52 formed on one side of the base 51, as shown in FIG. The weather strip 5 is integrally extruded,
Alternatively, the base portion 51 and the hollow seal lv portion 52 are extruded and then bonded together.

合される。On the other hand, the door has a stepped portion 4 at the boundary between the door body 3 and the door frame 2. In the hollow seal portion 52 of the weather strip 5, a portion corresponding to the step portion 4 is manufactured by molding, and this molded hollow seal portion 53 is joined to the base portion 51.

手部材に接触するなだらかな湾曲面の側面５２ａと、側
面が相手部材に押付けられたときに折られるように変形
する７字形の端面５２ｂを有する。The hollow seam A/capture 52 and the molded hollow seal portion 53 have a gently curved side surface 52a that contacts the mating member, and a 7-shaped end surface 52b that deforms so as to be folded when the side surface is pressed against the mating member. have

中空シーＡ７部５３０幅はドアの段部４の対応位置で最
大となり、更に下方へ狭くなっている。そして最大幅直
上付近には中空内を仕切る仕切壁５４が形成してちる。The side surface 52a of the molded hollow seal part 53 gradually bulges outward from the upper end (the right end in FIG. 2) downwards, and the width of the molded hollow seam A7 part 530 is at the corresponding position of the step part 4 of the door. It reaches its maximum and narrows further downward. A partition wall 54 is formed immediately above the maximum width to partition the inside of the hollow space.

で型成形中空シール部５３０幅は最大となっている。Directly below the partition wall 54, there is an opening 5 in the end surface 52a9111.
5 is formed, thereby forming a lip 56 on the side surface 52a. The thickness of the lip 56 is thicker on the partition wall 54 side, that is, on the upper half, and thinner on the lower half. The molded hollow seal portion 530 has a maximum width near the lower end of the lower half.

る。In the weather strip having the above structure, when the door is closed, the molded hollow seal portion 5
3 has an enlarged width and is provided with a partition wall 54, so that it fits well against the door frame 2. and partition wall 5
The upper half of the lip 56 that follows 4 has an expanded width, so it fits well with the door frame 2, and is thick, so the lower half of the lip 56 is attached to the door of the door body 3).
Press it against the top surface of 0. Since the lower half is lip-shaped and thin, it easily deforms to follow the shape of the upper end surface of the trim 30, and the gap 40 can be made as small as possible.

Since the sea A/wall surface at the position corresponding to the door step of the I/ section is used as a lip, it easily deforms and follows the sudden changes in the shape of the door.
Sound insulation can be improved by reducing the gap between the weather strip and the door. Furthermore, the lip has a smaller reaction force when pressed against the door than a hollow closed cross section, which can reduce the side door closing force.
