With the above-mentioned construction, the weather strip is inserted into the garnish portion of the door trim main body with the holding frame having a substantially U-shaped cross section provided on the main body made of a hard synthetic resin. Main body made of hard synthetic resin because it is connected and integrated by a fixture inserted from the receiving plate part so that the tip reaches the hollow part formed between the upper plate part and the garnish part of the holding frame part The lip made of soft synthetic resin integrated with the part functions as a sufficient weatherstrip for the glass window, and the weatherstrip can be used as a door trim body without using a conventional base member or core bar. The garnish part is firmly and integrally fixed. Next, the present invention will be described in detail with reference to the illustrated embodiment. In the drawing, reference numeral 1 denotes a door trim main body, 2 denotes a weatherstrip for a window glass seal mounted on 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 the back side of the front surface of the base material. The above configuration is basically the same as the conventional one. The weather strip 2 has an upper plate portion 22b having an upper portion connected to an upper portion of the substrate portion 21a, a connecting portion 22a having a downward end piece 22d, and a flat receiving plate portion 22c. The main body portion 21 having the stretched holding frame portion 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 provided on the back side of the substrate portion 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. In addition, the main body 21
The lip portion 24 and the lip portion 24 are usually integrally formed by an extrusion molding method or an injection molding method. However, it is also possible that the two are not integrally molded but separately molded and then laminated and integrated. Of course. The weatherstrip 2 is fitted into the front end of the garnish portion of the door trim body 1 with an opening formed between the front end of the receiving plate portion 22c of the holding frame portion 22 and the downward piece 22d. Receiving part 2
By attaching one side of the garnish portion to the upper plate portion 22b and the garnish portion, 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 d is formed, and 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 the structure for mounting it on the garnish portion are features 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 main body 1 and the glass window 10 is sealed. Since the weather strip 2 is composed of the main body portion 21 made of a hard synthetic resin and the lip portion 24 made of a soft synthetic resin, the door trim main body 1 is attached to the tip of the garnish by the main body portion 21 made of the hard synthetic resin.
Lip portion 24 made of a soft synthetic resin integrated with this
Will function as a sufficient weatherstrip for the glass window 10, and the attachment of the door trim body 1 to the garnish portion by the body portion 21 made of the hard synthetic resin will be described with reference to the cross-section provided at the upper portion of the body portion 21. The garnish portion is fitted to the tip of the garnish portion with the substantially U-shaped holding portion 22 so that one side of the garnish portion is attached to the flat receiving plate portion 22c, and the downward piece 22d is placed between the upper plate portion 22b and the garnish portion. By connecting and integrating with the fixture 5 inserted from the outside of the receiving plate 22c through the fixture insertion hole 22e so as to reach the cavity 4 having a depth corresponding to the length, the conventional base member and Even without using a cored bar, the weather strip 2 can be placed in the 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. Moreover, such a weather strip 2
The attachment of the garnish is performed by inserting the tip of the garnish into the holding frame portion 22 so that one side of the garnish portion is attached to the flat plate-shaped receiving plate portion 22c and reaching the hollow portion 4.
Can be reliably integrated by the fixture 5 inserted from the outside through the fixture insertion hole 22e, and can be performed extremely easily and in a short time without having to perform complicated positioning work and the like. Since there is no need to use an adhesive, there is no contamination due to leakage of the adhesive, and the tip of the fixture 5 in the cavity 4 is not hidden in the cavity 4 and does not protrude to the surface of the door trim. An excellent design surface is ensured, and fixing by the fixing tool 5 provides a sufficient fastening force and can be used for a long time. In addition, while the cutting process at the end portion of the skin material was conventionally difficult and the yield was poor, in the present invention, the garnish portion was simply cut and the skin material was wound around the base material and formed. Any difficult cutting work or the like for mounting the weather strip 2 is not required at all, and the processing yield of the skin material can be greatly improved. The fixing tool 5 inserted from the receiving plate portion 22c so that the tip reaches the hollow portion 4 may be a stapler type as shown in FIG. Even if it is a rivet type, other screws or stitchers may be used. Therefore, it is needless to say that the fixing tool insertion hole 22e may be formed by driving or screwing in without being provided in advance. As is apparent from the above description, the present invention provides a door trim main body and a weather strip that can be easily and reliably fixed and integrated without using a conventional metal base member. In addition, the number of parts can be reduced, the weight can be reduced, and the processing cost can be reduced. In addition, the connection work can be performed after the skin material is rolled into the base material, thereby increasing the degree of freedom of the mounting work. And the yield of the skin material can be significantly improved. Therefore, the present invention greatly contributes to industrial development as an automobile door trim which has eliminated the conventional problems.
