Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to automobile interior parts that are installed in vehicle body panels such as door trims and rear parcels.

<Prior art and its problems> As is well known, various interior parts such as door trims, side panels, rear parcels, etc. are installed in the interior of an automobile, and when installing these interior parts, the steps shown in Figure 3 are The flange portion 4 formed at one end of the clip 3 is attached to the dart hole 2 provided in the core material 1a of the interior component 1, and the elastic fitting piece 5 provided at the other end of the clip 3 is attached to the vehicle body panel 6. The interior component 1 is attached to the vehicle body panel 6 by being elastically fitted into the attachment hole 7 of the interior component 1.

The flange portion 4 consists of a head flange 4a formed at the tip of the clip, and a center flange 4b formed at a constant interval in the axial direction from the head flange 4a. After forming the material 1a into a desired shape and coating the surface of the core material 1a with the skin material 8, the clip 4 is attached from the back side of the core material 1a, so the head flange 4a of the clip 4 is polished. After inserting into the large diameter hole 2a of the hole 2, the clip 3 is held in the core material 1a by passing through the communication hole 2b and sliding into the small diameter hole 2c.

In FIG. 4, a state in which the interior component 1 is attached to the vehicle body panel 6 is shown.

Incidentally, recently, interior parts have become more and more sophisticated, and as a result, there is a tendency for the skin material used for the interior parts 1 to be made of high-grade materials, for example, breathable skin materials 8 such as carpets and woven fabrics. When these breathable skin materials 8 are used, air flows from the interior of the vehicle through the Daruma hole 2 (strictly speaking, the large diameter hole 2a) formed in the core material 1a, and this air inflow causes dust in the vehicle interior. There was a problem in that P such as dust adhered to the surface of the skin material 8, which significantly degraded the product design and was unfavorable for the interior environment of the car, especially in parts with many clip attachment points.

As a countermeasure to this problem, it has been proposed to close the pothole 2 with adhesive tape after inserting the clip, but this requires the above measures for each location where the clip is attached, which requires a large amount of work, and is not a practical solution. It wasn't.

《Purpose of the invention》 This invention was made in view of the above-mentioned circumstances, and its purpose is to make it possible to attach the clip from the back side of the core material, and to securely close the clip attachment hole. To provide an interior part for an automobile that prevents air from flowing in from inside the vehicle, keeps the surface of the interior component beautiful, and provides a good environment inside the vehicle.

<Configuration and Effects of the Invention> In order to achieve the above object, the present invention includes a molded core material molded into a desired shape, an air permeable skin material covering the surface of the core material, and an air permeable skin material that covers the surface of the core material at appropriate locations. An automobile interior part consisting of a clip for attaching a vehicle body panel that is attached to a round hole, the clip being attached to a head flange, a center flange, and a center flange formed on the outer periphery of the shaft at predetermined intervals in the axial direction. The head flange and center flange are set to have a larger diameter than the round hole, and a part of the head flange is cut out for insertion into the round hole. After the notch is formed and the surface of the molded core material is covered with a skin material, the notch part of the clip is attached to the round hole of the core material from the core material side, and the clip is rotated around the axis. The feature is that the clip is attached to a round hole.

That is, according to the above structure, round holes for inserting clips are provided at appropriate locations in the molded core material of the interior component, and the clips that are attached to the round holes have their head flange and center flange aligned with the above-mentioned shape. Since it is set to a larger diameter than the round hole, when the clip is attached to the molded core material, the round hole is completely blocked, reliably preventing air from entering from inside the passenger compartment. It is possible to reliably prevent dust, dirt, etc. from adhering to the surface of the trim component due to this air inflow.

Therefore, the surface of the product can be kept beautiful for a long period of time, and the interior environment of the vehicle can also be made good.

Furthermore, compared to the conventional structure in which the clip mounting hole is closed with adhesive tape or the like, in the present application, a notch formed in the head flange of the clip is inserted into a round hole made in the molded core material. Simply rotate the clip around the axis, and the clip can be attached to the proper position from the back side of the molded core material.
Therefore, since the round hole is hermetically sealed by the center flange of the clip, the above-mentioned effects can be obtained without any increase in the number of man-hours for attaching the clip, making it an extremely practical device.

<<Description of Embodiment>> Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view showing an automobile interior part according to the present invention, and FIG. 2 is a longitudinal sectional view of the same interior part.

In FIG. 1, reference numeral 10 indicates interior parts;
This interior component includes a molded core material 11 such as a hard board or composite resin board molded into a desired shape, a breathable skin material 12 such as a carpet or cloth material affixed to the surface of the molded core material 11, and the molded core material 12 such as a carpet or cloth material. A clip 1 is attached to a round hole 13 appropriately opened in the core material 11.
It is composed of 4.

The clip 14 attached to the round hole 13 is
Flange portion 15 attached to interior component 10 at one end
and an elastic fitting piece 1 that elastically fits into a mounting hole 17 provided in the vehicle body panel 16 at the other end.
It has 8.

More specifically, the flange portion 15 includes a head flange 19 and a center flange 20 formed on the outer periphery of the shaft at a predetermined interval in the axial direction of the clip 14.
A fan-shaped notch 21 is formed in a part of the head flange 19.

Furthermore, between the head flange 19 and the center flange 20, there is provided a neck portion 22 having a dimension approximately equal to the plate thickness of the molded core material 11.
20 are connected.

Next, when attaching the clip 14 to the molded core material 11, as shown in FIG. After inserting into the round hole 13 provided in the material 11, this clip 14
Just rotate it in the direction of the arrow in the figure. By rotating this clip 14 approximately once, the head flange 1
9 is located on the inner side of the molded core material 11 as shown in FIG. Since it is set to , the molded core material 11 can be held securely, and the round hole 13 can be airtightly sealed.

At this time, the diameter of the neck 22 of the clip 14 is set slightly smaller than the diameter of the round hole 13, so
The clip 14 can be moved minutely within the round hole 13, and can absorb slight installation errors when it is attached to the vehicle body panel 16.

As described above, in the interior part 10 according to the present invention, when the clip 14 is attached to the molded core material 11, the round hole 13 is reliably closed by the center flange 20 of the clip 14, so that the interior of the vehicle interior can be improved. Air inflow from the inside can be reliably prevented, and staining of the surface of the skin material 12 due to air inflow can be reliably prevented.

Furthermore, when attaching this clip 14, after inserting the notch 21 of the head flange 19 into the round hole 13, the clip 14 can be attached to the back side of the molded core material 11 by simply rotating the clip 14 about its axis. It can be inserted from the side and installed in the proper position.
The mounting operation is also extremely simple.

In addition, this invention eliminates the conventional Daruma hole,
Since it is possible to use a round hole, the punching die for forming the clip hole in the molded core material 11 can be simplified, and additional benefits include being able to use it in conjunction with a punching die for painted type single products. It also has
