Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to an improvement in a weatherstrip mounting structure in a vehicle door trim.

<< Prior Art >> Normally, a weather strip is attached to a waist flange portion of a door trim in order to provide a sealing function for a lifting window glass in a door trim installed in a door panel.

A conventional weather strip will be described with reference to FIG. 4. First, the weather strip 1 is integrally formed by embedding a core metal 3 having shape retention property inside an elastic body 2 such as rubber or soft resin. On one side surface of the weather strip 1, a sealing tongue piece 4 is slidably contacted with a window glass (not shown).

Then, the weather strip 1 is fixed to the surface of the waist flange portion 6 of the door trim 5 by a metal stitcher 7 or the like, and as shown in FIG.
The waist flange 6 of the door trim 5 is hung over the door trim 5, and the door trim 5 is attached to the door inner panel 8 by a fixing means such as a clip not shown.

<< Problems to be Solved by the Invention >> However, according to the conventional weather strip mounting structure, when the door trim 5 is attached to the door inner panel 8, as shown in FIG. The lower edge 6a of 6 is the door inner panel 8
When the wood-based core material is used as the core material 5a of the door trim 5, the core material 5a is broken as shown in FIG. 7, or the core material 5a is broken as shown in FIG. The upper edge 8a of the door inner panel 8 between the core material 5a and the skin material 5b.
It has been pointed out that there is a defect that the metal stitcher 7 is destroyed due to the penetration of the metal strip and the attachment of the weather strip 1 is damaged.

The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent the weather strip from being attached when the door trim is attached to the door inner panel, and to not remove the core material of the attrim. It is an object of the present invention to provide a weatherstrip mounting structure capable of preventing breakage of the door trim core material even when a wood-based core material is used, and significantly improving the workability of mounting the door trim.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention is for an automobile including a core material formed into a required shape and a skin material integrally attached to the surface side of the core material. In a vehicle weatherstrip mounting structure to be attached to a waist flange portion of a door trim, a lower end side of the weatherstrip is formed to be extended, and the extension is bent inward to provide a bent portion, It is characterized in that the lower end edge of the waist flange portion of the door trim is covered with the curved portion.

<Operation> As is apparent from the above configuration, even if an error occurs in the position where the door trim is attached, the lower edge of the waist flange of the door trim core is covered with the weatherstrip, so that the tip of the door inner panel is covered. Can surely be prevented from invading the inside of the door trim core material and entering between the core material and the skin material.

<Example> Hereinafter, a mounting structure of an automobile weather strip according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view showing a state where a weather strip is attached to a door trim side, FIG. 2 is a vertical sectional view showing a state where the weather strip is attached to a door trim, and FIG. 3 is another embodiment of the present invention. It is sectional drawing which shows the state which attached the strip to the door trim.

In FIG. 1, a weather strip 10 comprises a metal cored bar 11 and an elastic body 12 such as a soft vinyl chloride resin or rubber on the outer periphery thereof.
The seal tongue piece 13 slidably contacting the elevating window glass is provided on one side surface thereof.

On the other hand, the door trim 20 to which the weather strip 10 is attached is made of a laminated structure in which a skin material 22 lined with a foam layer is coated in order to impart cushioning properties to the surface of a wood-based core material 21 formed into a required shape. In order to attach the weather strip 10 described above, a waist flange portion 23 bent downward is provided.

Further, the waist flange portion 23 is set to a flat surface so that the weather strip 10 can be stably attached.

By the way, the feature of the present invention is that the door trim 20 having the weather strip 10 attached thereto can be easily and quickly attached to the door inner panel, and at the time of attachment, the door trim core material 21 is devised so as not to be destroyed. .

That is, the vertical dimension of the weather strip 10 (indicated by 1 in FIG. 1) is usually the waist flange portion of the door trim 20.
The size is set so as to match the vertical width dimension of 23, but in the present invention, the lower end side of the weather strip 10 is further extended and the extended portion is bent inward to form the bent portion 14. The bent portion 14 is formed so that the lower end edge of the waist flange portion 23 of the door trim 20 is protected so as to be wound.

The bent portion 14 may be formed before the weather strip 10 is attached to the door trim 20, and at that time, the bent portion 14 is fitted to the lower end edge of the waist flange portion 23 of the door trim 20, With the bent portion 14 as a starting point, the weather strip 10 is brought into contact with the surface of the waist flange portion 23, and the both may be fixed by the metal stitcher 30.

Further, after the weather strip 10 is attached to the waist flange portion 23 of the door trim 20, the lower end side of the weather strip 10 may be bent and fixed so that the lower end edge of the waist flange portion 23 is wound.

Therefore, as shown in FIG. 2, the lower end edge 23a of the waist flange portion 23 of the door trim 20 is attached to the weather strip 10.
Since the structure is such that the door trim 20 is mounted on the door inner panel 40 so as to be hooked on the upper edge of the door inner panel 40, even if there is a mounting error, the tip 40a of the door inner panel 40 will have a weather strip. Ten
Only by hitting the bent portion 14 of the wood-based core material 21 is not destroyed, and the tip 40a of the door inner panel 40 does not enter the wood-based core material 21 and the skin material 22, and the weather strip 10 It does not hinder the installation of.

If the injection-molded core material is used as the core material of the door trim 20, the problem of core material destruction does not occur, but the tip of the door inner panel is inserted between the skin material and the core material. This can be prevented by the bent portion 14 of the strip.

Next, FIG. 3 shows another embodiment of the weather strip 10 for an automobile according to the present invention. In this embodiment, a bent portion 14 provided on the weather strip 10 is shown.
The outer surface of the corner portion is rounded. By doing so, there is an advantage that the bent portion 14 functions as a guide when the door trim 20 is mounted, and the insertion work of the door trim 20 becomes easier. .

<< Advantages of the Invention >> As described above, according to the attachment structure of the weather strip according to the present invention, the lower end side of the weather strip is extended and the bent portion for protecting the lower end edge of the waist flange portion of the door trim is formed. Due to the configuration, the upper edge of the door inner panel does not bite into the interior of the door trim core material due to variations in installation work, and does not enter between the door trim core material and the skin material. The strip can be effectively prevented from coming off, and the workability of mounting the door trim can be improved.
