[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention secures a resin clip mounting seat to the back surface of an automobile interior part having a downwardly facing flange portion along the side edge, and mounts on this clip mounting seat. In the mounting structure of the interior parts for automobiles, which is mounted by press-fitting the clip into the mounting hole of the vehicle body panel, the clip mounting seat has an extension piece extendingly formed to be joined to the rear surface of the flange portion. In addition, ribs, bosses, and other projections formed integrally with this extension piece are engaged and fixed in the locking holes of the vehicle body panel.

[0009]

[Action]

 As is clear from the above configuration, the extension piece extended from the clip mounting seat is joined and fixed along the back surface of the flange part of the internal component, so this extension piece enhances the rigidity of the flange part. By engaging and fixing the protrusions that are provided integrally with the extension pieces in the locking holes of the vehicle body panel, the flange part of the interior parts is integrated with the vehicle body panel, and the strength of the flange part is significantly strengthened. ..

【Example】

 Hereinafter, an embodiment of a mounting structure for an automobile interior component according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an automobile door trim to which the attachment structure according to the present invention is applied, and FIG. 2 is a sectional view showing a state in which the automobile door trim is attached to a vehicle body panel.

In FIGS. 1 and 2, an automobile door trim 10 is configured by attaching a skin material 12 to the front surface side of a resin core material 11 formed into a required shape.

More specifically, the resin core material 11 is obtained by extruding a mixture of polypropylene resin and wood powder in an appropriate mixing ratio into a sheet by a T-die extrusion molding machine, heating and softening it, and then forming the desired shape. It is formed into the required shape by cold press forming on the above, and the above skin material 12 uses a PVC sheet laminated with a pad layer such as polyurethane foam on the back surface, and when the resin core material 11 is cold pressed. At the same time, the laminate is integrated.

Further, the automobile door trim 10 is provided with a flange portion 13 that faces downward along the rear end edge due to the requirement of modeling, and the flange portion 13 gives a stereoscopic effect to the door trim 10. In addition, it has a function to blindly attach a mounting member such as a clip mounting seat described later.

By the way, the feature of the present invention resides in that in the mounting structure of the vehicle door trim 10, the deformation of the flange portion 13 is prevented in advance.

That is, the clip mounting seat 20 joined and fixed to the back surface of the resin core material 11 is made of an injection molded body of polypropylene resin, has mounting flanges 21 on both sides, and has a clip 30 mounted in the center. The clip seat portion 22 is formed one step higher than the mounting flange 21, and the extension piece 23 that is joined and fixed to the mounting flange 21 on one side along the rear surface of the flange portion 13 of the door trim 10 is integrally extended. Has been formed.

Further, a projection (a rib 24 in this embodiment) is integrated with the extension piece 23, and a tip end portion 24 a of the rib 24 projects from the clip seat portion 22 of the clip mounting seat 20.

Then, after fixing the clip mounting seat 20 to the back surface of the resin core material 11 of the door trim 10 by ultrasonic welding or the like, the clip 30 mounted on the clip seating portion 22 is press-fitted into the mounting hole 41 of the vehicle body panel 40. The door trim 10 is completely attached to the vehicle body panel 40 by engaging and fixing the tip end portion 24a of the rib 24 integrally formed with the extension piece 23 in the locking hole 42 of the vehicle body panel 40. ..

Therefore, the flange portion 13, which is apt to be deformed due to the fluctuation of the environmental temperature, is reinforced by the extension piece 23 of the clip mounting seat 20, and the rib 24 integrally formed with the extension piece 23 has the body panel. Since the flange portion 13 is integrated with the vehicle body panel 40 through the rib 24 of the clip mounting seat 20 because it is engaged and fixed in the locking hole 42 of the 40, heat contraction and external force due to environmental temperature fluctuations. However, it does not deform, and the good appearance of the peripheral portion of the door trim 10 can be maintained for a long period of time.

Further, the clip mounting seat 20 in which the extension piece 23 and the rib 24 are integrated may be welded and fixed to the back surface of the resin core material 11 of the door trim 10, and the flange portion may be attached to the vehicle body panel as in the conventional countermeasure. It has the advantage of being simpler and less expensive than the method of fixing with screws. A boss may be used instead of the NAO and the rib 24.

[0021]

[Effect of the device]

 As described above, in the mounting structure for an automobile interior part according to the present invention, an extension piece is integrally provided on a clip mounting seat fixed to the back side of the interior part, and the extension piece is joined and fixed to the rear surface of the flange part of the interior part. At the same time, the ribs, bosses, and other protrusions formed on the extension piece are engaged and fixed in the locking holes of the vehicle panel. Since it is configured to be integrated with the vehicle body panel via the ribs and bosses of the clip mounting seat, the flange portion does not deform even if contraction due to environmental temperature changes or external stress is applied. It has the effect of maintaining a beautiful appearance for a long time along the peripheral edge of the component.

Further, since the clip mounting seat integrally formed with the extension piece and the projection is fixedly joined to the back surface of the interior component, the flange portion of the interior component can be prevented from being deformed. Compared with the conventional example in which the flange part is screwed and fixed to the vehicle body panel, it can be implemented easily and at low cost, so it has high practical value.
