Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to the terminal shape of interior parts.

(Prior art) Interior parts such as front pillar garnishes and consoles of vehicles are made by overlaying a skin layer on a base layer made of a synthetic resin material via a pad layer, and at least the part of the terminal part that directly touches the field of view. Conventionally, as shown in FIG. 10, end treatment was performed by wrapping a pad layer 32 and a skin layer 33 around a base layer 31.

(Problems to be solved by the invention) As described above, in the past, terminal processing was required as post-processing.

Therefore, the purpose of the present invention is to eliminate the need for post-processing,
Focusing on three-layer pressure molding, which allows end treatment to be performed simultaneously during product molding, the present invention aims to provide an end shape for interior products in which at least the end portion that directly touches the field of view is made into an undercut shape to maintain good appearance. be.

(Means for solving the problem) In order to achieve the above object, the present invention provides a base layer 1
2. The pad layer 13 and the skin layer 14 are formed by three-layer pressure molding to form the interior parts 11 and 21, and at least a part of the end portion is formed from the skin layer 14 side to the base layer 12.
It is characterized by being formed into an undercut shape 15 that bends to the side.

(Example) Examples will be described below based on the accompanying drawings.

Figure 1 shows the garnish that covers the front pillar of the vehicle from the inside of the vehicle, and Figure 2 shows the garnish.
FIG.

As is known, a windshield 3 is fitted into the front pillar 1 from the front via a molding 5 etc., and a trim 6 is fitted into a flange piece 2 formed to protrude in the longitudinal direction at the rear of the pillar 1. A front pillar garnish 11 that covers the pillar 1 from the inside of the vehicle interior is installed between the front glass and the windshield 3 in the vertical direction.

The garnish 11 includes a base layer 12 made of a synthetic resin material, a pad layer 13 superimposed on the surface of the base layer 12, and a skin layer 14 superimposed on the surface of the base layer 12.
The three-layer body is formed into a predetermined product shape by pressure forming.

Here, pressure forming means, as illustrated in FIG. 11, that after heating a flat resin material A, a predetermined mold B is formed.
, put on the airtight lid C, and in the meantime,
It is molded by applying an air pressure of about 3 atm, and then cut, etc., as necessary.
Even if it has a complicated shape such as the undercut-shaped portion E, there is an advantage that it can be easily molded.
In the figure, F is an air vent passage provided in mold B.

Garnish 1 during the above three-layer pressure forming
At least the part of the end portion of the skin layer 14 that directly touches the visual field is formed into an undercut shape so that the edge of the skin layer 14 does not face the visual field.

In the embodiment, the undercut-shaped end portions include a front edge portion of the garnish 11 along the side of the windshield 3, an upper edge portion along the roof garnish 9, and a lower front edge portion along the lower portion of the windshield 3. However, the terminal portion that does not directly touch the other field of view is left with a simple shape without undercutting.

First of all, Figure 2 shows the front pillar garnish 11.
The front edge along the side of the windshield 3 is shown, and the three layers 12, 13, 14 are bent from the skin layer 14 side to the base layer 12 side at the time of the three-layer pressure forming to form the undercut shaped portion 15. Form.

On the other hand, a thin layer 4 of black ceramic is applied to the inner surface of the side of the windshield 3 where the undercut shaped part 15 faces, so that the undercut shaped part 15 is not visible through the windshield 3 from the front outside the vehicle. Do it like this.

Next, the upper edge of the front pillar garnish 11 along the roof garnish 9 is also formed into an undercut-shaped portion 16 similar to that described above, as shown in FIG. The lower front edge along the line is also formed into a similar undercut-shaped portion 17 as shown in FIG.

On the other hand, since the lower edge of the front pillar garnish 11 along the instrument panel (not shown) does not come into direct contact with the visual field from inside the vehicle, it has a simple shape without an undercut as shown in FIG. The trailing edge along trim 6 is also the second
In the illustrated embodiment, the trim 6 is covered with a lip portion 7 that is integrated with the trim 6, so the shape is similarly kept simple.

In this way, the end portions that directly touch the field of view of the front pillar garnish 11 are simultaneously formed in the undercut portions 15, 16, and 17 bent from the skin layer 14 side to the base layer 12 side during three-layer pressure forming of the product. Eliminating conventional terminal processing,
Good appearance can be maintained while increasing productivity.

Incidentally, in the above embodiments, the undercut-shaped portion was made into a relatively large bent portion, but as shown in FIG. Undercut-shaped portion 18 in which the base layer 14 is slightly bent
It may be formed into

Further, even when the lip portion 7 is not provided on the molding 6, if it is formed into an undercut-shaped portion 19 which is a similar small bent portion as shown in FIG. 7, a good appearance can be maintained. In this case as well, it goes without saying that a large undercut-shaped portion may be used as in the above-described embodiment.

Next, examples regarding other interior items will be described.

FIG. 8 is a perspective view of the console, and FIG. 9 is a cross-sectional view taken along the line --.

As is known, the console 21 is opened downward,
The upper wall has a box-like shape with an opening 22 from which a change lever (not shown) projects, and the console 21 also has three layers 12, 13, 14 similar to those described above.
is formed into a product shape by pressure forming.

During such three-layer pressure molding, the console 21
The lower end peripheral edge portion opened downward is formed into an undercut-shaped portion 25 that bends inward, and
The peripheral edge of the opening 22 provided in the upper wall is formed into an undercut-shaped portion 26 that bends downward.

As described above, the present invention can be applied to the console 21, and can also be applied to other interior items such as the center pillar garnish.

(Effects of the invention) As described above, according to the invention, at least a part of the end portion of the interior component is formed into an undercut shape bent from the skin layer to the base layer side by three-layer pressure forming. It is possible to eliminate the need for post-processing of the end treatment of wrapping the pad layer and the skin layer around the layer, and it is possible to mold the interior product with high productivity while maintaining a good appearance.
