Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior material with a decorative member used for automobiles and a method for manufacturing the same.

[0002]

2. Description of the Related Art For example, in the case of an automobile door trim, FIG.
As shown in FIG. 3, an armrest portion (2) is formed as a deep-drawing forming portion on the main body substrate (1) of the door trim. Conventionally, the material of the main body substrate (1) is resin felt, wood fiber felt, resin felt-polypropylene laminate,
Wood fiber felt-polypropylene laminated board, acrylonitrile-butadiene-styrene resin (ABS) board, polyvinyl chloride (PVC) board, etc. are used. Then, after molding the above material into the main body substrate (1), the skin material (3) is pressure-bonded to the surface of the substrate (1) to manufacture the door trim (4).

[0003]

However, in the above-mentioned conventional door trim (4), when the main body substrate (1) is molded, the tensile stress is applied to the material at the armrest part (2) as a deep-drawing part. As a result, the armrest part (2) and its vicinity are torn (2A), rough part (2B), etc., and even if the skin material (3) is stuck on it, the torn (2A) However, there is a problem in that the rough portion (2B) is felt as a concave portion.

Defects such as the breakage (2A) and the rough portion (2B) occur in a portion of the material of the base material (1) having a small internal structural strength, but the internal structure of the base material (1) is nonuniform. Therefore, the above defect does not occur at a certain place, so that it is difficult to take a countermeasure against the defect.

[0005]

As a means for solving the above-mentioned conventional problems, the present invention has a deep-drawing forming part (2), and an interior material body and a decorating member attached to the surface of the interior material body. In the interior material (4) with a decorative member consisting of (7), a slit (5) is provided in the vicinity of the deep drawing part (2) of the main body substrate (1) of the interior material (4), An interior material with a decorative member, in which the main body substrate (1) surface is covered with a main body skin material (3) and the slit (5) is covered and hidden by a hard decorative member (7), Slit (5) near the part of the material to be molded (1A) in which the deep drawing part (2) is to be molded
And the material to be molded (1A) is molded into the main body base material (1) of the interior material (4), and then the main body base material (1) is coated with the main body skin material (3) and the slit is formed. (5) The present invention provides a method for producing an interior material with a decorative member, in which a hard decorative member (7) is mounted on a part.

[0006]

In the present invention, when molding the main body substrate (1) of the interior material (4), a slit is formed near the deep-drawing portion (2).
(5) is provided. In this way, the deep-drawing part
Even if tensile stress is applied to the material (1A) during molding of (2),
The stress is absorbed by the opening of the slit (5), and the stress is hardly exerted on the material (1A). Therefore, the molded base material (1) is torn and no rough portion is formed.

On the surface of the main body substrate (1), the main body skin material (3)
Since the hard decorating member (7) is attached on the slit (5) part, the slit (5) part is covered and hidden by the hard decorating member (7), and the feeling from the surface is felt. It will not be done.

[0008]

EXAMPLE The present invention will be described with reference to an example shown in FIGS. 1 to 5. As shown in FIG. 1, the main body of the interior material (4) is a base material.
The material (1A) of (1) is molded by a press molding machine (8) consisting of an upper mold (8A) and a lower mold (8B), and as shown in FIG. ) Body substrate having
It becomes (1).

Prior to press molding, a slit is formed in the place where the material (1A) of the main body substrate (1) is present, or press molding is performed,
Or the armrest part of the upper die (8A) of the press molding machine (8)
Attach the cutting edge (8D) near the forming part (8C) of (2), and
The slit (5) is provided in the material (1A) by (8D). If the slit (5) is provided in this way, the armrest part
The tensile stress exerted on the material (1A) when (2) is molded is absorbed by the opening of the slit (5), and the molded main body substrate (1) is torn and rough parts are generated. Is prevented. The main body substrate (1) has the slit at the same time.
(5) The decorative member fitting groove (6) is formed in the peripheral edge of the portion.

As the material (1A) for the main body substrate (1), resin felt, wood fiber felt, resin felt-polypropylene laminate, wood fiber felt-polypropylene laminate, acrylonitrile-butadiene-styrene resin ( An ABS plate, a polyvinyl chloride (PVC) plate, etc. are used.

Next, as shown in FIG. 3, the main body base material (1) is coated with the main body skin material (3), and at the same time or after that, the decorating member (7) is attached to the main body base material (1). Mounted over the slit (5). As shown in FIG. 4, the decorating member (7) is composed of a hard substrate (7A) and a skin material (7B), and a flange (7C) is formed on the peripheral edge thereof.
The decorative member (7) is attached to the main body of the interior material (4) as shown in Fig. 5 by being fitted into the fitting groove (6) of (1) through the body skin material (3). To be

The slit (5) portion of the main body substrate (1) is thus covered and hidden by the decorating member (7), and the decorating member (7) has a hard substrate (7A) and is hard. Therefore, the slit (5) is not felt at all from the surface of the interior material (4) shown in FIG.

Examples of the material of the main body skin material (3) are sheets of polyvinyl chloride leather, polyamide leather, polyester leather, non-woven fabric, fiber knitted fabric or the like, or sheets and polyethylene foam, polypropylene foam, polyurethane foam, etc. A laminated sheet or the like with a plastic foam sheet of is used, and the skin material (7) of the decorative member (7) is used.
As B), the same material as the main body skin material (3) is used, but it is desirable to use a material having a different color and / or a different material from the main body skin material (3).

As the material of the hard substrate (7A) of the decorating member (7), ABS plate, PVC plate, hard plastic plate such as polypropylene plate, metal plate, wood plate, etc. are used.

[0015]

Therefore, according to the present invention, it is possible to obtain an interior material having an excellent appearance in which no unevenness is felt from the surface.
