BACKGROUND OF THE INVENTION
The present invention relates to an automobile interior part provided with a clip mounting seat having a shock absorbing function such as a door trim, a rear side trim, or a luggage side trim.
[0002]
[Prior art]
As conventional interior parts for automobiles of this type, door trims shown in FIGS. 5 to 7 are known.
[0003]
FIG. 5 is an exploded perspective view of a conventional door trim, FIG. 6 is a C arrow view of FIG. 5, and FIG. 7 is a C arrow view of FIG. 5 after the door trim is assembled.
[0004]
According to FIGS. 5 to 7, the door trim is constituted by a trim main body a composed of a trim upper b and a trim lower c which are divided into two parts, and an outer flange d of the trim upper b and an outer flange e of the trim lower c. The two are joined together by superimposing them and joining the two end joints f, g together.
[0005]
For joining the trim upper b and the trim lower c, a plurality of mounting bosses h are erected on the back surface side of the tip joint portion g on the trim lower c side, and a mounting hole i to which the mounting boss h is fitted is provided at the tip on the trim upper b side. Provided at the joint portion f, after fitting the attachment boss h into the attachment hole i, the tip end side of the attachment boss h is melted by vibration welding or the like and welded to the tip joint portion f on the trim upper b side. .
[0006]
Further, a substantially U-shaped clip mounting seat j that is open in the vertical direction is provided so as to straddle the rear surface of the trim lower c and the outer flange e thereof, and the clip k mounted on the clip mounting seat j is attached to the body panel side. The trim main body a is mounted on the vehicle body panel by fitting and engaging with the mounting hole.

[Problems to be solved by the invention]
In the conventional structure configured as described above, the clip mounting seat j is formed in a substantially U-shape because the impact of the side impact is caused by the buckling deformation of the clip mounting seat j against the side impact of the automobile. In order to form the substantially U-shaped clip mounting seat j in the joint g of the trim lower c, the slide piece o is used for the trim lower c mold.
[0009]
Depending on the design requirement for buckling deformation or the shape of the joint with the trim upper b side, the vertical wall-shaped pedestal portion of the clip mounting seat j needs to be set high.

In this way, when the pedestal portion of the clip mounting seat j is set high, the clip mounting seat j itself falls down and is easily buckled and deformed, and the clip mounted thereon is fitted to the mounting hole side on the vehicle body panel side. When engaging, the clip is difficult to be engaged and engaged with the mounting hole on the vehicle body panel side.
[0011]
Therefore, by forming the reinforcing ribs m projecting outward on the pedestal portion of the clip mounting seat j, an attempt is made to prevent buckling deformation at the time of clip mounting due to the fall of the clip seat j. As a result, the slide piece o for forming the clip mounting seat j is increased in size, which causes an increase in the cost of the door trim itself.
[0012]
Further, even if the clip mounting seat j is formed by the slide piece o, if it is too close to the outer flange e, the clip mounting seat j is formed on the outer flange e or the clip mounting seat h on which the slide piece o is formed. In order to solve this problem, the mounting boss h viewed in a chain line in FIG. 6 is provided. In this case, a floating phenomenon of the trim upper b with respect to the trim lower c occurs at the corners where the outer flange e and the step n of the joint g intersect.
[0013]
Accordingly, the present invention has been devised in view of the prior art, and firstly, the seat due to the fall of the mounting clip seat when the clip is mounted without providing a reinforcing rib that causes an increase in the size of the slide piece o. An object of the present invention is to provide an automobile interior part that can prevent bending deformation.
[0014]
