Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile interior part such as an automobile door trim, and more particularly to an automobile interior part capable of performing a terminal treatment of a decorative sheet with good appearance and efficiency.

[0002]

2. Description of the Related Art Recently, in order to improve the comfortability of the interior of a vehicle, the materials of interior parts such as automobile door trims are upgraded, or decorative sheets such as cloths and carpets are attached at appropriate places on the surface of the door trims. The method is being tried.

9 and 10 show an outline of the structure of an automobile door trim. An automobile door trim 1 is formed by adhering a skin material 3 to the surface of a core material 2 formed in a required shape. The door trim main body 4 and a decorative sheet 5 such as a cloth, which is attached to the surface of the door trim main body 4 to add a decorative property to the appropriate places.

As a material for the decorative sheet 5, a cloth 6 having a superior surface appearance and feel, which is laminated with a cushion material 7 on the back surface thereof, is used to improve decorativeness and cushioning property. As a method for mounting the decorative sheet 5, the following method has been conventionally performed.

First, as shown in FIG. 11, the lower die 8 for crimping is used.
After mounting the decorative sheet 5 with the peripheral edge clamped on the mold surface, the crimping upper mold 9 on which the door trim body 4 is set is lowered, and the crimping upper and lower molds 8 and 9 are attached to the door trim body 4. Then, the decorative sheet 5 is pressure bonded.

Further, as shown in FIG. 12, in a state where the decorative sheet 5 is pressure-bonded to the door trim body 4, the hot-melt cutting blade 8a provided around the outer periphery of the lower pressure-bonding die 8 is raised. After cutting the decorative sheet 5 along the outer peripheral trim cut shape, the wood grain bar 8b installed between the lower crimping die 8 and the hot-melt cutting blade 8a rises, and the wood grain formed on the door trim body 4 Decorative sheet 5 in the groove 4a for use
The pressed peripheral edge portion 5a of the
Is performing terminal processing.

[0007]

As described above, the cushion material 7 is conventionally provided on the back surface of the cloth 6 which is the material of the decorative sheet 5 in the automobile door trim 1 in which the decorative sheet 5 is mounted on an appropriate place on the surface. In the laminated product, as shown in FIG. 13, due to the texture-like property of the cloth 6, defects such as thread fraying and omission of the cloth end occur at the cut portion of the cloth 6, and the frayed portion from the wood grain groove 4a is external. It has been pointed out that there is a problem that the external appearance is remarkably deteriorated such as being exposed to the outside.

Further, although the groove width of the wood-grooving groove portion 4a is usually set narrow in terms of molding, for example, when a thick cloth such as moquette is set as the material of the cloth 6, the thickness of the cloth 6 and the cushion material 7 are set. The total thickness becomes very large, and as shown in FIG. 14, when the terminal portion 5a of the decorative sheet 5 is inserted into the wood grain groove 4a together with the wood grain bar 8b, an excessive external force in the arrow direction is applied to the wood grain groove 4a. As a result, defects such as cracks and cracks are likely to occur in the wood grain groove 4a, and therefore, there is a problem that the degree of freedom in material selection is limited, such as being greatly restricted by the thickness and specifications of the cloth 6.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an interior part for an automobile in which a trim body is provided with a decorative sheet composed of a cloth and a cushion material. Another object of the present invention is to provide interior parts for automobiles having a high practical value, such as improving the appearance of the terminal portion of the decorative sheet, smoothly performing the terminal processing work, and freely selecting the cloth material.

[0010]

In order to achieve the above object, the present invention provides an interior for an automobile, which comprises a trim body molded into a required shape and a decorative sheet mounted on a predetermined position on the surface of the trim body. In the component, the terminal portion of the decorative sheet is subjected to compression flattening, and the terminal portion is set to be thin.

[0011]

As is apparent from the above construction, if compression flattening is applied along the end portion of the decorative sheet, the occurrence of thread fraying at the cloth end portion can be prevented.

Furthermore, when selecting a cloth material, even if a thick cloth is used, since the portion to be inserted into the wood grain groove is set to be thin, it is possible to use a thick cloth. No defects such as cracks occur in the wood-grooving groove.

Further, since the end portion of the decorative sheet is set to be thin, it is possible to smoothly perform the press-fitting operation into the grain-grooving groove and the winding operation on the back side of the core material.
