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 such as an automobile door trim and a method for producing the interior material.

[0002]

2. Description of the Related Art An automobile door trim as shown in FIG.
(1) is composed of a base material (2) formed into a predetermined shape and a skin material (3) adhered to the surface of the base material (2). For example, a decorative member (on the upper side of the armrest part (4) ( 5) is installed. The decorative member (5) is different from the skin material (3) in color, color tone, material, etc., and gives the door trim (1) a decorative property.

Conventionally, as shown in FIG. 7, the decorative member of the base material (1) is mounted on the door trim (1) by attaching the decorative member (5).
(5) A wood-graining method is adopted in which the periphery of the mounting portion is surrounded by a groove (6) and the peripheral edge portion (5A) of the decorative member (5) is wood-grained into the groove (6) through a skin material (3). (US Pat. No. 4,779,
390).

[0004]

However, in the above wood-graining method, the groove (6) must be formed at the time of molding the base material (1), and the molding die for the base material (1) has grooves and protrusions for that purpose. Must be provided, resulting in high die cost and easy damage to the groove and the protruding portion. Further, it is necessary to provide a groove and a protrusion corresponding to a vacuum pressure bonding die for pressure-bonding the base material to the skin material and the decorative member, which increases the cost of the die as well as the molding die and is easily damaged.

[0005]

Means for Solving the Problems As a means for solving the above conventional problems, the present invention is to decorate an interior material (1) consisting of a base material (2) and a skin material (3) at a predetermined portion of a main body. Member mounting recess
(1A) is formed, and a decorative member (5) composed of a cushion core material (5A) and a skin material (5B) covering the cushion core material (5A) is fitted into the recess (1A). Providing interior materials (1) with decorative members,
In addition, place a vertical wall on the mold surface of the lower mold (9) of the vacuum crimp mold (7).
A decorative member mounting portion (10) surrounded by (11) is provided, the decorative member mounting portion (10) is provided with a cushion core material (5A), and a skin material (5B that covers the cushion core material (5A). ) A decorative member consisting of
(5) is set in a slightly compressed state, the interior material (1) on the lower mold (9) is vacuum-molded with the skin material (3) of the main body, and the decorating member (5) and the skin material (3) And the interior material (1) molded into a predetermined shape from above, and the base material (2) of the main body is pressure-bonded, and the interior material with a decorative member obtained in this manner is vacuum-pressed (7). The present invention provides a method for manufacturing an interior material (1) with a decorative member, which is removed from (1).

[0006]

[Function] In the interior material (1) of the present invention, the vacuum pressure bonding type
(7) Cushion core material on the decorative member mounting part (10) of the lower mold (9)
Since the decorative member (5) consisting of (5A) and the skin material (5B) covering the cushion core material (5A) is set in a slightly compressed state, after the interior material (1) is manufactured, it is vacuum-pressed. When removed from (7), the decorative member (5) is elastically restored to the vertical wall (11) of the decorative member mounting portion (10) of the lower mold (9) of the vacuum crimping mold (7). )
Of the interior material (1)
The peripheral wall (1B) of (1A) and the decorative member (5) are in close contact with each other without a gap.

In the present invention, for example, a resin board, a wood fiber board, a cardboard, a polystyrene foam board or the like is used as the base material (2), and the skin material (3) is a polyvinyl chloride sheet or a thermoplastic elastomer sheet (for example, A thermoplastic sheet such as a polyolefin thermoplastic elastomer sheet or a polyester thermoplastic elastomer sheet), or a thermoplastic sheet and a plastic foam such as a polyethylene foam, a polypropylene foam, a polyvinyl chloride foam, or a polyurethane foam. Laminated sheets are used.

Further, the decorative member (5) is a polyurethane foam,
Cushion core material such as polyethylene foam, polypropylene foam, felt (5A) and fiber knitted woven fabric covering the cushion core material (5A), non-woven fabric, natural leather, synthetic leather, skin material such as polyvinyl chloride leather ( 5B) and.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 4. A base material (2) of a door trim (1) molded in a predetermined shape by a molding die as shown in FIG. Type
(7) is set on the upper mold (8), while the lower mold (9) is provided with a decorative member mounting portion (10) surrounded by a vertical wall (11) at a predetermined position. The lower mold (9) is composed of a porous air-permeable electric mold and a ceramic mold, and is connected to the vacuum path (12).

As shown in FIG. 1, the decorative core mounting member (10) of the lower mold (9) of the vacuum crimping mold (7) is covered with a cushion core material (5A) and the cushion core material (5A). The decorative member (5) including the skin material (5B) is set in a slightly compressed state, and the adhesive (13) is applied to the back surface of the decorative member (5). The lower mold
The skin material (3) is inserted between the (9) and the upper mold (8) in a heat-softened state, and as shown in Fig. 2, the skin material (3) is a lower mold.
Vacuum-formed by (9) and with decorative material (5) and adhesive (1
The skin material (3) is bonded by the base material (2) between the lower mold (9) and the upper mold (8) at the same time. And the lower mold
The decorative member mounting portion (10) of (9) is a skin material together with the decorative member (5).
It is fitted into the decorative member mounting recess (2A) formed in the base material (2) via (3).

Thus, as shown in FIG. 3, the decorative member-equipped door trim (1) in which the decorative member (5) is fitted in the decorative member mounting recess (1A) of the main body is manufactured. Door trim (1)
Is removed from the vacuum crimp mold (7). At this time, the decorative member
(5) is a slightly compressed state and the lower mold (9) of the vacuum crimping mold (7)
The decorative member (5) is elastically restored when the door trim (1) is taken out from the vacuum crimping mold (7) because it is set on the decorative member mounting portion (10). Crimping mold (7) lower mold
The thickness of the vertical wall (11) of the decorative member mounting portion (10) of (9) is filled, and the interior material (1) Peripheral wall (1B) of the decorative member mounting recess (1A) of the main body
The decorative member (5) and the decorative member (5) are in close contact with each other as shown in FIG.

Other than the above embodiment, as the decorative member (5), as shown in FIG. 5, a cushion core material (5A) is covered with a skin material (5B) and a plastic plate (5C) is adhered to the back surface. You may. In this case, the shape may be restored in advance as shown in the figure.

[0013]

Therefore, in the present invention, since it is not necessary to form a groove for wood grain in the periphery of the decoration member mounting portion of the interior material, a molding die or a vacuum pressure bonding mold used for producing the interior material with the decoration member can be used. The structure is simplified and less likely to be damaged, and the mold cost is greatly reduced.
