Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontally long automobile interior part mounted on the interior surface of a vehicle body panel.
Moreover, the present invention relates to an automobile interior part that can be easily and reliably fixed to a panel.

[0002]

2. Description of the Related Art With the recent increase in outdoor life, demand for RV vehicles such as one-box cars and wagon cars has been increasing.

[0003] Since this type of RV vehicle requires a large multifunctional space on the rear side in the passenger compartment, the size of the rear side panel of the vehicle along the front-rear direction is set to be very long. Also, the dimensions of the rear side trim are set to be long along the front-rear direction of the vehicle, that is, horizontally long.

FIG. 8 is a front view of a rear side trim 1 attached to a vehicle body panel as viewed from the indoor side. The rear side trim 1 is formed by press molding a polypropylene (PP) resin mixed with a filler such as talc. The armrest 1a and the storage box 1 are formed at the center of the front in consideration of the functionality.
b, accessory parts such as the speaker grill 1c are attached.

In the structure for fixing the rear side trim 1 to the vehicle body panel side, since the rear side trim 1 is set to be horizontally long, first, the center of the rear side trim 1 (the place where the speaker grill 1c is installed) is attached to the vehicle body panel. It is fixed with screws.

Thereafter, the front edge and the rear edge of the rear side trim 1 are fixed to the vehicle body panel.
For example, when a resin clip is used, a difference in thermal shrinkage between the panel and the rear side trim 1 may cause the resin clip to come off when shrinkage distortion occurs in the rear side trim 1. For installation, the front edge and the rear edge of the rear side trim 1 are firmly fixed to the panel by screw fixing, respectively.

More specifically, FIG. 9 shows a cross-sectional structure for fixing the rear edge of the rear side trim 1 to the vehicle body panel 2. An embossed portion 3 is provided at a fixing point of the rear side trim 1, and an embossed portion is provided in a mounting hole 2 a of the vehicle body panel 2. By screwing and fixing the screw 4 by aligning the screw holes 3a of the part 3, the screw 4 is securely and firmly fixed at each fixing point of the rear side trim 1 by the screw 4.

[0008]

As described above, in the conventional rear side trim 1, since the screws 4 are fixed at the fixing points at the front and rear edge portions, the heads of the screws 4 are fixed from the indoor side. However, there is a problem that the appearance performance is deteriorated, and as a countermeasure, when an ornament cap is attached to the embossed portion 3, the cost is increased, so that it is not an effective countermeasure.

Further, the work of tightening the screw 4 must be performed for each fixing point, and the mounting work is troublesome.
The problem of reducing productivity has also been pointed out.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables a horizontally long automobile interior part to be attached to a vehicle body panel in a short time, and enhances the appearance and design of a vehicle interior at a fixed point. It aims to provide parts.

[0011]

In order to achieve the above-mentioned object, an invention according to claim 1 of the present application is directed to a horizontally long automobile interior part mounted on the indoor surface of a vehicle body panel, Fixing points to the vehicle body panel are set at both ends in the longitudinal direction of the interior component. At the fixing point, a mounting pedestal protruding toward the vehicle body panel is integrally formed on the back surface of the interior component, and the body panel is fitted to the mounting pedestal surface. A hollow box-shaped fitting boss with increased rigidity fitted into the fitting hole is provided upright.

According to the first aspect of the present invention,
Instead of the conventional screwing work, a fitting boss is erected on a mounting pedestal protruding from the back of the interior component, and the fitting boss is fitted and fixed in a fitting hole of the vehicle body panel,
Good appearance performance can be obtained because mounting fixtures such as screws are not conspicuous on the product surface and sink does not occur on the product surface.

Furthermore, compared with the conventional screwing work, the fitting boss is fitted and fixed in the fitting hole of the vehicle body panel, so that the mounting work is completed in a short time without the need for a mounting jig such as a screwdriver. Can be.

The invention described in claim 2 of this application is characterized in that a guide taper surface is provided on an outer surface of the fitting boss.

According to the second aspect of the present invention,
Since the tapered surface is formed on the outer surface of the fitting boss formed on the mounting base, when the fitting boss is fitted into the fitting hole of the vehicle body panel, the tapered surface acts as a guide, so that the interior Even if the locating positions of the parts are slightly varied, smooth mounting work can be expected.

The invention described in claim 3 of this application is characterized in that the mounting pedestal is provided with a locking hole for locking a resin clip engaged with the clip hole of the vehicle body panel.

According to the third aspect of the present invention,
The mounting pedestal is provided with a locking hole for attaching a resin clip so as to be adjacent to the fitting boss. In addition to the fitting, the resin clip is engaged with the clip hole of the vehicle body panel, so that the mounting strength of the interior component can be made stronger.

The invention described in claim 4 of the present application is to set the size of the fitting boss longer than the size of the resin clip attached to the locking hole of the mounting pedestal. It is characterized by having a locate function.

According to the fourth aspect of the present invention,
By setting the length of the fitting boss higher than the dimensional length of the resin clip attached to the locking hole of the mounting base,
When the interior component is mounted on the vehicle body panel, the fitting boss is first inserted into the fitting hole, so that the locate function of the fitting boss can be effectively operated.
