Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an improvement of a clip for attaching an interior part to a vehicle body panel.

<Prior art and its problems> As is well known, various interior parts such as door trims, body sides, and rear parcels are installed inside automobiles, and these types of interior parts are made of wood fiberboard as shown in Figure 3. A molded core material 1 formed by molding a composite resin plate or the like into a desired shape, a pad material 2 such as a plastic foam, and a skin material 3 such as a PVC sheet are integrated on the surface side of the molded core material 1 via an adhesive. In order to attach this kind of interior parts to the car body panel 4, the clip mounting seat 5, which bulges out toward the car body panel 4 side, is attached to the molded core material 1.
By attaching the clip 6 to the clip mounting seat 5 and press-fitting the elastic fitting piece 6a of the clip 6 into the mounting hole 4a of the vehicle body panel 4, it can be attached to the vehicle body panel 4. This makes it easy to install interior parts.

However, in such a mounting structure for the clip 6, the head flange 6b and center flange 6c, which are located on the front and back sides of the clip mounting seat 5 and hold the clip mounting seat 5 under pressure, are thin. In particular, the head flange 6b does not have sufficient rigidity, and since the adhesive A is applied to the inner surface of the clip mounting seat 5, the adhesive A is interposed between the head flange 6b and the mounting seat 5. was unavoidable.

As a result, the head flange 6b of the clip 6 frequently moves into and out of contact with the inner surface of the mounting seat 5 due to vibrations during running, which causes the adhesive A interposed between the two to make a sticky sound. It was hot.

As a countermeasure for this, adhesive A can be applied to the clip mounting seat 5.
It has also been proposed to use a masking plate 7 as shown in FIG. 4 to prevent the coating from being applied to the inner surface of the core material 1. However, the process of fixing the masking plate 7 to the core material 1 and the material cost of the masking plate 7 are Taking these factors into consideration, this was not an effective measure in terms of man-hours and costs.

《Purpose of the invention》 This invention was made in view of the above-mentioned circumstances.The purpose of the invention is to improve the shape of the clip to eliminate abnormalities during driving without using a masking plate. To provide a clip for attaching interior parts that reliably prevents noise generation.

《Structure 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 and an adhesive bonded to cover the surface of the molded core material. An interior parts attachment clip for attaching an interior part made of a pad material and a skin material to a vehicle body panel,
Clip mounting seats are formed at appropriate locations on the molded core material to protrude toward the vehicle body. The head flange is equipped with a head flange that holds the mounting seat, a center flange, and an elastic fitting piece that is fitted into the mounting hole of the vehicle body panel. By processing the rounded surface, only the base of the head flange comes into contact with the inner surface of the clip mounting seat, which prevents the adhesive sound between the head flange and the mounting seat. do.

In other words, the clip for attaching interior parts used in this invention has a thick head flange, which improves rigidity, and the inner surface of the head flange, that is, the side facing the mounting seat, has a rounded surface. Since the contact area with the adhesive between the mounting seats is significantly reduced, the head flange may bend due to vibrations during driving and may come into contact with or separate from the adhesive. There is no need to repeat this process, and since the contact area with the adhesive can be reduced, the adhesive noise can be prevented as much as possible, and quiet running can be expected.

Further, in the present invention, since a masking plate is not used and quiet running can be expected, the man-hours for installing the masking plate, the cost of materials for the masking plate, etc. can be reduced, which is advantageous in terms of man-hours and cost.

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

FIG. 1 is a sectional view of a main part of a door trim attached to a vehicle body panel using the present clip, and FIG. 2 is a sectional view showing a modification of the same clip.

In FIG. 1, reference numeral 10 indicates an automobile door trim. This door trim 10 includes a molded core material 11 such as a hard board or a composite resin board formed into a desired shape, and an adhesive on the surface of the molded core material 11. A pad material 12 made of polypropylene foam, polyethylene foam, etc., which is integrally adhered and fixed through the
It is composed of a skin material 13 such as a PVC sheet.

Furthermore, clip mounting seats 15 are formed at appropriate locations on the molded core material 11, and bulge toward the vehicle body panel 14 side.

On the other hand, the clip 16 attached to the clip mounting seat 15 has a head flange 17 and a center flange 18 on one end thereof, which hold the clip mounting seat 15 under pressure from the front and back sides of the clip mounting seat 15, and Elastic fitting pieces 19 that elastically fit into the mounting holes 14a of the vehicle body panel 14 are formed on the other end sides. The head flange 17 and the center flange 18 are disposed around the outer periphery of the clip 16 with a predetermined interval (approximately equal to the plate thickness of the clip mounting seat 15) in the axial direction of the clip 16. Further, a skirt-shaped seal piece 20 is provided below the center flange 18, and
4 and its peripheral edge abuts to provide good sealing performance.

Furthermore, in the present invention, the shape of the head flange 17 of the clip 16 is set to be thick as shown in FIG.
7a is rounded. For example, conventionally,
The thickness of the head flange of the clip was approximately 0.8 mm, but in the case of the present application, by setting the thickness to 0.8 to 2.0 mm, this head flange 17
The head flange 17 is provided with rigidity so that the head flange 17 will not rattle against the clip mounting seat 15 even due to vibrations during driving.
The lower surface 17a of the clip mounting seat 15 is rounded to avoid contact with the adhesive A attached to the inner surface of the clip mounting seat 15.
It is constructed to reliably prevent the sound of adhesive from sticking.

Next, in the clip 16' shown in FIG. 2, the lower surface 17a of the head flange 17 is rounded and textured, and the texture 21 further reduces the contact area of the lower surface 17a of the head flange 17 with the adhesive. By doing so, the sound of adhesive sticking can be further prevented compared to the clip 16 of the above embodiment.

As described above, the clip for attaching interior parts according to the present application has a simple structure in which the shape of the head flange 17 of the clip 16 is devised;
It has the effect of preventing as much as possible the adhesive noise that was caused by the repeated contact and separation between the clip head flange and the clip mounting seat due to vibrations during driving, and is extremely practical. It is an idea.
