Description

[Detailed Description of the Invention] This invention relates to a structure for attaching clips to interior parts of automobiles such as rear corners and rear sides.

Automotive interior parts such as rear corners, rear sides, and center pillars generally use injection-molded synthetic resin molded products as core materials, with a skin material pasted on the surface and multiple metal clips attached to the back surface. The clip is configured to be mounted on the body inner panel by press-fitting the clip into the mounting hole of the panel.

In order to attach the metal clip to an interior component such as a rear corner, conventionally, as shown in FIG. 3. A structure in which both ends are fixed to the core material 4 of the interior component with rivets 5, 5, or as shown in FIG. A structure is adopted in which one end of 3 is inserted and supported here, and only the other end is fixed with a rivet 5.

However, all of these conventional clip attachment structures require riveting, which requires a large number of man-hours and has the problem of poor workability.

This invention was made in view of the above-mentioned conventional problems, and a pair of clip holding parts each having an arcuate wall with one end sealed are formed on the back surface of the core material of an interior component, projecting rotationally symmetrically to each other, and A positioning rib is formed on the inside of the arcuate wall, and a notch that engages with the rib is formed at both ends of the base of the stub, which has a clip portion protruding from approximately the center of the flat base. Therefore, it is an object of the present invention to provide a clip attachment structure for an automobile interior part, which allows the above-mentioned clip to be attached with a single touch without requiring attachment parts such as rivets.

An embodiment of this invention will be described below based on the drawings.

Figures 3 and 4 show core material 1 for automotive interior parts such as rear corners.
1, a pair of clip holding parts 12, 12 formed on the back surface of the clip holding part 12.12 have an arcuate wall 12b sealed at one end 12a, and protrude at rotationally symmetrical positions with respect to each other as shown in FIG. The arcuate wall 1
A knob 13 for positioning is provided protruding from the inside of 2b.

On the other hand, as shown in FIG. 5, the clip 14 has a flat base 15 made of a spring material with a clip portion 16 cut and raised approximately at the center thereof, and the ribs 13 on both ends of the rounded base 15.
Notches 17, 17 are formed to engage with the base part 15, and the base part 15 is curved downward in an arcuate manner as a whole in order to prevent rattling during installation.

Then, as shown in FIG. 6, the clip 14 is rotated in the direction of the arrow from between both clip holders 12.12, so that the base 15 is inserted into the clip holder 12.12.
is inserted, and at the rotational position where the inserted base 15 abuts the sealing end 12a of the arcuate wall 12b, the notches 17.17 at the tip engage with the ribs 13, 13, respectively, thereby firmly fixing the base 15. It will be done.

Therefore, according to the above clip attachment structure, the clip 14
It can be attached with one touch by rotating approximately 90 degrees with fingers or the like, which is extremely easy to work with, and in the attached state, engagement between the knob 13 and the notch 17 prevents it from falling off, etc. Due to the elasticity of the base portion 15, there is no backlash or the like, and sufficient strength for practical use can be obtained.

Moreover, as is clear from FIGS. 3 and 4, the clip holding portion 12.12 is a core type that forms the front and back surfaces of the core material 11,
The core material has a shape that allows normal mold opening using only the cavity mold, and is easy to mold when injection molding, for example, and has a clip holding part 12, 12 without any special cost increase. 11 moldings are possible.

As is clear from the above explanation, in the clip attachment structure for automobile interior parts according to this invention, the clip can be attached with one touch to the clip holding part formed on the back side of the core material of the interior part without using screws, rivets, etc. Since the clip can be attached with the clip, the efficiency of the clip attaching work can be significantly improved, and costs can be reduced.

In addition, in the present invention, since the clip holding part has an arcuate wall with one end sealed, when the clip is engaged with the clip holding part, both ends of the base of the clip abut against the arcuate wall. Since the longitudinal direction of the clip is restricted, the attachment strength is improved.

Furthermore, since the clip is curved downward by a spring material, when the base of the clip is rotated and inserted into the clip holding part, the elasticity of the curved base prevents it from wobbling and also eliminates rattling noise. This has the effect of preventing the occurrence of.
