In the figure, 1 is a door trim main body, 2 is a weather strip for a window glass seal attached to a garnish portion of the door trim main body 1, and the door trim main body 1 is a fabric in which a urethane foam layer is formed on a back surface of a base material. It is attached with a skin material, and the above configuration is basically the same as the conventional one.

The weather strip 2 has an upper plate portion 22b whose upper end is a connecting portion 22a on the front side of the upper end of the substrate portion 21a and a tip end thereof is a downward piece 22d and a flat plate-like receiving plate portion 22c. A main body 21 having a stretched holding frame 22 having a substantially U-shaped cross section is molded from a hard synthetic resin such as a hard vinyl chloride resin, and a soft synthetic resin such as a soft vinyl chloride resin is formed on the back side of the substrate 21a. A lip portion 24 made of resin is stretched, and a fixture insertion hole 22e is provided in the receiving plate portion 22c of the holding frame portion 22 having a substantially U-shaped cross section. The main body 21
The lip portion 24 and the lip portion 24 are usually integrally formed by an extrusion molding method, an injection molding method, or the like, but they may be separately molded without being integrally molded, and then they may be bonded and integrated. Of course.

The weather strip 2 is fitted in an opening formed between the tip of the receiving plate portion 22c of the holding frame portion 22 and the downward piece 22d at the tip of the garnish portion of the door trim body 1 and is fitted in a flat plate shape. Support plate 2
By attaching one surface of the garnish portion to 2c, the downwardly facing piece 22 is provided between the upper plate portion 22b and the garnish portion.
The cavity 4 having a depth corresponding to the length of d is formed, and the cavity 5 is connected and integrated by the fixture 5 inserted through the fixture insertion hole 22e from the outside of the receiving plate 22c so that the tip reaches the cavity 4. The special weather strip 2 and its mounting structure to the garnish portion are characteristic of the present invention.

The door trim thus obtained is similar to the conventional one in that the weather strip 2 is attached to the tip of the garnish portion of the door trim body 1 to seal the glass window 10, but in the present invention, Since the weather strip 2 is composed of the main body portion 21 made of hard synthetic resin and the lip portion 24 made of soft synthetic resin, the main body portion 21 made of hard synthetic resin is attached to the garnish tip portion of the door trim main body 1.
Lip part 24 made of soft synthetic resin integrated with this
Has a sufficient function as a weather strip for the glass window 10, and the body portion 21 made of the hard synthetic resin described above is attached to the garnish portion of the door trim body 1 by a cross section provided on the upper portion of the body portion 21. The substantially U-shaped holding portion 22 is fitted into the tip of the garnish portion so that one side of the garnish portion is attached to the flat plate-like receiving plate portion 22c, and the downward facing piece 22d is provided between the upper plate portion 22b and the garnish portion. By connecting and integrating by the fixture 5 inserted from the outside of the receiving plate portion 22c through the fixture insertion hole 22e so as to reach the cavity portion 4 having a depth corresponding to the length, the conventional base member and Even if the core bar is not used, the weather strip 2 has an opening formed between the tip of the receiving plate portion 22c and the downward piece 22d. Firmly no rattle it becomes to be integrally fixed with respect to the door trim main body 1 by the fixing member 5 in a state of being restricted to have.

An excellent design surface is secured, and fixing with the fixture 5 provides a sufficient fastening force and can be used for a long period of time. Further, conventionally, it was difficult to cut at the end portion of the skin material and the yield was deteriorated, whereas in the present invention, the garnish portion is simply cut, or the base material is wound and molded. Even if the cutting work for attaching the weather strip 2 is not necessary at all, the processing yield of the skin material can be greatly improved.

It should be noted that as the fixture 5 inserted into the cavity 4 by the receiving plate 22c so that the tip thereof reaches the cavity 4, even if it is of a stapler type as shown in FIG. 1, it is as shown in FIG. It may be of a rivet type or may be a screw or a stitcher. Therefore, it is needless to say that the fixture insertion hole 22e may be formed by driving or screwing without being provided in advance.
