Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door trim which has a high mounting accuracy and is excellent in workability in assembling and disassembling.

[0002]

2. Description of the Related Art As a mounting structure for integrally fixing a vehicle door trim body panel, a weather strip and a door trim main body, as shown in Japanese Utility Model Laid-Open No. 61-26618, a weather strip is provided at the upper edge of the door trim main body. An L-shaped trim base for mounting is fixed, the trim base is hooked to the upper edge of the body panel to be temporarily fixed, and the two are connected and fixed with a clip or the like (so-called hook type), or the actual open sho 62-112636. It is widely known that, as disclosed in the publication, a clip attached to a door trim is directly inserted into a weather strip attached to an upper end portion of a body panel in a lateral direction of a vehicle to fix the two (so-called horizontal mounting type). Has been.

However, in the former case, since the trim base is temporarily fixed to the body panel while it is permanently fixed, there is a problem that the construction accuracy is poor and an abnormal noise is generated. If another standard member is used to improve accuracy, assembly and disassembly workability will deteriorate and cost will increase.On the other hand, in the latter case, mounting work will be performed in a blind state. There is a problem that the workability is extremely poor, and it is necessary to increase the strength of the door trim in order to secure sufficient rigidity of the connecting portion, which causes a significant cost increase.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, has a high mounting accuracy, and can reliably prevent the generation of abnormal noise during traveling, and furthermore, the assembling work. The present invention has been completed for the purpose of providing an automobile door trim which is excellent in productivity and disassembling workability, and can greatly enhance productivity, and can also significantly reduce production cost.

[0005]

The vehicle door trim of the present invention, which has been made to solve the above-mentioned problems, has the upper end of the body panel formed in a downward U-shaped groove and is provided at the base of the weather strip. While the U-shaped connecting portion is fitted, a downward base piece is provided at the upper end of the door trim body attached to the front side of the body panel, and the base piece is engaged with the inside of the U-shaped connecting portion. The upper end of the body panel and the upper end of the door trim body are connected and integrated via the weather strip.

[0006]

With this structure, the body panel and the weather strip are provided at the base of the weather strip with respect to the U groove formed at the upper end of the body panel.
In addition to fitting and connecting the character-shaped connecting portion, the upper end of the door trim attached to the front side of the body panel has a base piece portion which is provided downward from the upper portion of the door trim, so that the U-shaped connecting portion of the weather strip is Since they are engaged with each other, the upper ends of the body panel and the door trim are properly connected and integrated with each other with the weather strip interposed therebetween without rattling.

[0007]

The present invention will now be described in detail with reference to the illustrated embodiments. In the figure, 1 is a body panel, 2 is a body panel 1.
A weather strip 3 attached to the upper end of the door trim body 3 attached to the front side of the body panel 1, and the door trim body 3 is a base plate 3b made of a synthetic resin base material.
The surface material 3a is attached to the surface of the. An upper end of the body panel 1 is formed in a downward U-shaped groove portion 4, and a U-shaped connecting portion 5 that can be fitted into the U-shaped groove portion 4 is integrally provided at a base portion of the weather strip 2 and a door trim. The inner groove 5a of the U-shaped connecting portion 5 is provided at the upper end of the main body 3.
An L-shaped base piece 6 having a downward insertion portion 6a that can be inserted therein is provided, and the tip of this insertion portion 6a is engaged with the engagement portion 5b at the groove bottom of the inner groove 5a. Bulge edge 6b
There is. Further, the upper end edge of the U groove portion 4 is formed on the engaging edge 4c with the engaging groove 2a formed on the weather strip 2, and when the weather strip 2 is fitted into the U groove portion 4 by the engagement of both, both I try not to come off.

The U groove portion 4 is formed by cutting and raising a flange 4a at the upper end of the body panel 1 as shown in FIG. 4b is a reinforcing bead for the flange 4a, and 1b is a door inner reinforcement. Further, when the door trim body 3 is composed of a sufficiently strong, for example, iron plate molding trim 3d, the upper end edge portion is bent as shown in FIG.
Can be continuously provided. Further, when the door trim main body 3 is composed of the synthetic resin molding trim 3c, the base piece 6 is integrally molded at the upper end edge as shown in FIG. It can also be one. However, in this case, it is preferable to provide reinforcing ribs 6c and 6c on both sides of the base piece 6.

Further, as shown in FIG. 5, the U-groove portion 4 may be formed in a shape that widens toward the bottom. In this case, the U-shaped connecting portion 5 of the weather strip 2 is fitted. Is preferable because it can be made stronger. Further, as shown in FIG. 6, folds 2b and 2b may be provided on either or both of the inner surface and the outer surface of the U-shaped connecting portion 5 of the weather strip 2 in this case. Insertability and fitting force of the piece 6 into the inner groove 5a, and U
It is preferable because the insertability of the character-shaped connecting portion 5 itself into the U groove portion 4 and the fitting force can be made stronger. Further, as shown in FIG. 7, the base piece 6 is cut at the side edge of the downward insertion portion 6a.
When the recessed portion 6d is formed, U in this portion
Since the connecting force between the character-shaped connecting portion 5 and the inner groove 5a becomes low, it becomes possible to easily separate the character-shaped connecting portion 5 from the inner groove 5a starting from the notch portion 6d, and the disassembly workability of the door trim can be improved. Therefore, it is preferable.

Next, the assembling process of the automobile door trim constructed as described above will be described with reference to the embodiment shown in FIG. 1. U of the weather strip 2 is inserted into the U groove 4 formed in the upper end of the body panel 1. The weather strip 2 is connected to the body panel 1 by fitting the character-shaped connecting portion 5 and engaging the engaging edge 4c with the engaging groove 2a. Then, by inserting the base piece 6 of the door trim main body 3 attached to the front side of the body panel 1 into the inner groove 5a of the U-shaped connecting portion 5, the upper end of the door trim main body 3 is temporarily fixed to the body panel 1. Stop. After that, when the body panel 1, the weather strip 2, and the door trim body 3 are accurately positioned, if the door trim body 3 and the body panel 1 are connected by a clip or the like according to a conventional method, they can be securely and properly positioned. It will be fixed integrally. In this case, since the body panel 1, the weather strip 2, and the door trim body 3 are firmly fixed without any gap or the like, it is possible to reliably prevent the generation of abnormal noise, and to assemble them. The work and disassembly work can be performed extremely easily.

[0011]

As is apparent from the above description, the present invention has a high mounting accuracy and can reliably prevent the generation of abnormal noise, and is excellent in the assembling workability and the disassembling workability. The productivity can be improved and the production cost can be significantly reduced.
Therefore, the present invention has an extremely great contribution to the development of industry as an automobile door trim that eliminates the conventional problems.
