Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door trim having an ornament part of a gather specification.

[0002]

2. Description of the Related Art In order to improve the decorativeness of an ornament portion formed on a door trim, when a gather (wrinkle) specification is formed, conventionally, as shown in FIG. 4 and FIG. A volume pad 32 made of a urethane pad or a nonwoven fabric formed in the same shape as that for increasing the volume feeling was adhered to the surface of the substantially flat base 31 formed with the shape with an adhesive, and then gathered in advance. An ornament assembly 34 is formed by covering and adhering a surface material 33 such as soft leather so as to wrap the surface of the volume pad 32, and then the ornament assembly 34 is made of a fiber material and a binder such as resin. It is configured to be fixed to the ornament portion of the door trim base material 35 by nail caulking or heat welding. .

[0003]

However, in the case of the above-described conventional door trim, since the ornament assembly is formed in a separate process and then assembled to the door trim base material, a large number of components are required and time is required for production. And the gathers formed on the skin material 33 are unstable and may disappear at the time of heating and bonding, resulting in a decrease in appearance quality.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a door trim which can be easily manufactured with a small number of components and which is stable in quality. Is to do.

[0005]

Means for Solving the Problems In order to solve the above problems, the present invention is configured as follows. Claim 1
The invention is a door trim, a door trim base material having a gather-like uneven portion formed in the ornament setting portion,
It is characterized by comprising a pad adhered to the ornament setting portion and a skin material adhered to the entire surface of the door trim base material including the surface of the pad.

According to the first aspect of the present invention, the ornament is integrally formed with the door trim. As a result, only two parts, a pad and a skin material, are required except for the door trim base material, and an ornament base made of an iron plate or a hard synthetic resin is omitted, which leads to a reduction in weight and a stable quality. A door trim having an ornament portion is configured.

Further, since the ornament portion can be formed in the process of manufacturing the door trim, the time required for manufacturing the door trim can be reduced as compared with the conventional method in which the ornament portion is formed in a separate process and then assembled. Is done. Further, since the pad and the molded skin are adhered along the uneven portion of the door trim base material along the gather, a gather-like shape is maintained, and the quality can be stabilized.

[0008]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a schematic front view showing the entire door trim according to the present embodiment, and FIG.
FIG. 4A is a cross-sectional view taken along line A, where FIG.
(B) shows the state after bonding. FIG. 3 is an explanatory view showing a welding mode of the peripheral portion of the ornament portion.

As shown in the figure, a door trim 1 arranged to cover the surface of a door inner panel includes a door trim base 2 made of a wood-based or glass-based fiber and a binder such as a resin, and the door trim. Of the surface of the substrate 2,
A part 2a corresponding to a part forming the ornament part 1a in the door trim 1 (hereinafter, referred to as an ornament setting part)
Pad 3 for increasing volume feeling adhered to the surface of
And soft leather 4 as a skin material made of a synthetic resin sheet such as vinyl chloride or polypropylene which is adhered so as to cover the entire surface of the door trim base material 2 including the pad 3.

The ornament setting portion 2a of the door trim base 2 has a substantially corrugated uneven portion 2b for forming a gather-like shape. Accordingly, the pad 3 adhered to the surface of the ornament setting portion 2a and the soft leather 4 adhered to the surface of the pad 3 have irregularities along the irregularities 2b, that is, a gather-like shape having decorativeness. Is formed.

As the pad 3, a urethane foam or vinyl chloride foam pad or a soft material such as nonwoven fabric or cotton is used. As shown in FIG. 3, the peripheral edge of the ornamental portion 1a is crushed by high-frequency welding to form a groove 5, whereby the molded skin 4 corresponding to the outer peripheral edge of the pad 3 is formed by the pad 3 and the door trim base. It is strongly adhered to the material 2 and the appearance quality of the outer periphery of the ornament 2a is stabilized.

The door trim 1 constructed as described above is manufactured as follows. As shown in FIG. 2A, a door trim base material 2 having an uneven portion 2b for forming a gather-like shape in an ornament setting portion 2a is heat-formed into a predetermined shape by, for example, a hot press mold. Subsequently, the pad 3 is bonded to the surface of the ornament setting portion 2a of the door trim base material 2 with an adhesive. Further, an adhesive is applied to the entire surface of the door trim base material 2 including the pad 3, and the soft leather 4 is bonded by vacuum molding or pressure bonding. Thus, an ornament part 1a having a three-layer structure is formed as shown in FIG.

Subsequently, the peripheral edge of the ornamental portion 1a is crushed by high frequency welding using a welding horn 6 designed as shown in FIG. 3, thereby forming a groove 5 having a beautiful design. The outer appearance quality of the outer periphery of the portion 1a is stabilized. That is, in the three-layer structure including the door trim base material 2, the pad 3, and the soft leather 4, when the second-layer pad 3 is partially interposed, the pad 3 is displaced from the target set position. easy. In this case, the groove 5 is formed by crushing the peripheral edge of the ornament portion 1a by high-frequency welding as described above, thereby absorbing the displacement and stabilizing the appearance quality of the outer peripheral edge of the ornament portion 1a. In addition, the decorativeness can be improved. Further, a strong adhesive force of the soft leather 4 to the pad 3 can be obtained. When performing such high-frequency welding, the material of the pad 3 is made of vinyl chloride.

As described above, the door trim 1 according to the present embodiment is different from the conventional one in which the ornament assembly is manufactured in a separate process and then assembled to the door trim base material, and the ornament portion 1a is manufactured in the door trim 1. Since the parts can be manufactured simultaneously in the process, the number of parts is reduced to only two parts except for the door trim base material 2, the number of components is significantly reduced, and the number of assembling steps is also reduced, so that the cost can be reduced.

Furthermore, in this embodiment, since the door trim base material 2 also serves as an ornament base, the weight is reduced as compared with the conventional case where an iron plate or a synthetic resin is used as the ornament base in the ornament portion. . In addition, the gather-like shape formed on the ornamental portion 1a as described above is formed by bonding the pad 3 and the soft leather 4 along the corrugated uneven portion 2b of the door trim base material 2, so that the quality is high. It will be stable.

In this embodiment, the case where the skin material of the door trim 1 is made of the soft leather 4 is described. However, the present invention is not limited to this case. There may be.

[0017]

As described in detail above, according to the present invention,
It is possible to provide a door trim having a small number of components and having an ornamental portion that is stable in quality, and it is possible to provide a door trim that is easy to manufacture and effective in reducing costs.
