Field of the Invention The present invention relates to a combined structure of a door trim mounted on the entire surface of a door inner panel and a corner cover installed on the door inner panel corresponding to a location where a door mirror is installed. The present invention relates to a combined structure of a door trim and a corner cover that eliminates scratches generated between the door cover and the corner cover, improves aesthetics, and enhances the mounting strength of the door trim.

[0002]

2. Description of the Related Art Normally, as shown in FIG. 7, an automobile door trim 1 mounted on a door inner panel (not shown).
A corner cover 3 made of a resin molded body is installed on the upper edge of the front side of the to cover the mounting portion of the door mirror 2.

The structure for fitting the door trim 1 and the corner cover 3 and the mounting structure for the door inner panel are as shown in FIG.
The resin clip 4 is attached to the clip mounting seat 3a formed on the back surface, and is fixed to the door inner panel 5 through the resin clip 4, and the door inner panel 5
The door trim 1 is attached to the entire interior side of the door via a clip (not shown), and the waist end 6 of the door trim 1 is abutted against the surface of the corner cover 3 to form a combined structure of the door trim 1 and the corner cover 3.

[0004]

However, in the conventional structure for combining the door trim 1 and the corner cover 3, the corner cover 3 is designed because the waist end 6 of the door trim 1 is abutted against the surface of the corner cover 3.
It has been pointed out that due to a dimensional error, a mounting error, etc. of the door trim 1, a gap is likely to occur between the waist end 6 of the door trim 1 and the corner cover 3 and the interior aesthetics are significantly deteriorated.

Further, the front side of the door trim 1 is shaped so as to bulge toward the inside of the vehicle compartment so as to substantially contact the side edge of an instrument pad (not shown), and as shown in FIG. The door inner panel 5
The gap between the door trim 1 and the door trim 1 becomes very large, it is difficult to set the contact ribs 7 and the like for the purpose of reinforcement, and it is difficult to strengthen the rigidity of the front side of the door trim 1.
There is a problem that the front side of the door trim 1 is likely to be flexibly deformed.

Further, in order to prevent a gap between the corner cover 3 and the door trim 1, as shown in FIG.
The waist trim end 5 is bent downward and the waist trim end 5 is housed in the groove 8.
Attempts have been made to eliminate the gap between the waist end terminal 6 and the corner cover 3 of the door trim 1. In such a case, the door trim 1 attaches the skin material 1b to the surface of the core material 1a, and the skin material extends along the terminal. Since 1b is wound around the back surface of the core material 1a, it is difficult to insert the waist end 6 into the groove portion 8, and the skin material 1b may be peeled off.

The plate-shaped vertical deflection restriction ribs that come into contact with each other and the insertion piece that is inserted into the mounting hole of the receiving plate are shaped. Characterized in that it is.

Further, when the core material of the door trim is formed by injection molding or mold press molding, the vertical deflection restricting rib and the insertion piece may be integrally formed with the core material of the door trim. When using a wood fiber board or a thermoplastic resin board as the above, the waist garnish made of a synthetic resin molded body mounted on the back surface of the waist portion of the door trim may be integrally provided with the ribs for regulating the vertical deflection and the insert piece. Good.

Further, a vehicle width direction deflection regulating rib is provided integrally with or separately from the vertical direction deflection regulating rib, and the vehicle width direction deflection regulating rib is brought into contact with the indoor end edge of the receiving plate provided on the corner cover. It may be installed in.

[0011]

As apparent from the above structure, when the corner cover is attached to the door inner panel, the contact ribs provided on the lower surface of the receiving plate come into contact with the door inner panel, so that the corner cover is provided at the lower edge of the corner cover. The receiving plate is firmly fixed to the door inner panel via a contact rib.

[0012] Further, with the upper surface of the receiving plate of the corner cover being brought into contact with the vertical deflection regulating rib provided on the rear surface of the door trim, and the insertion piece inserted in the mounting hole of the receiving plate, the door trim is inserted. By attaching the to the door inner panel, even if a downward load is applied to the waist of the door trim, the ribs for vertical deflection function as a stopper on the surface of the receiving plate, so the waist of the door trim moves downward. It does not flex and deform.

Further, since the insertion piece is inserted in the mounting hole of the receiving plate, no gap is generated between the surface of the corner cover and the waist end of the door trim. Further, since the vertical deflection regulating rib is formed at a position separated from the end of the waist portion, the skin material can be smoothly rolled up in the waist portion of the door trim.
