Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to interior parts of vehicles including automobiles, houses, and others, and particularly to interior parts with uneven surfaces.

<Prior Art> Examples of conventional interior parts include those shown in FIGS. 5 to 8 (see Nissan Service Bulletin No. 466, page 68, published by Nissan Motor Co., Ltd.).

A door trim 3 and a rear side finisher 4 as "interior parts" are attached to the sides of a door 1 and a rear seat 2, respectively, inside the vehicle interior. The door trim 3 and the rear side finisher 4 have almost the same structure, so the door trim 3 will be explained below as a representative. The door trim 3 consists of a slab urethane pad 5, a PVC sheet 6, and a curved steel plate 7. A waist part A formed by overlapping the above steel plates 7 and a thermoplastic resin whose surface is covered with a cloth 8 as a "covering material" and a recessed part 9 is provided in the center. A central part B consisting of a polyester stock 10 made of
is fixed with a screw 11, and the armrest part 12 is integrally formed with an overhang part C.
It has a piece configuration and is attached with one end of the steel plate 7 of the waist portion A hooked above the door inner panel (not shown). The recessed portion 9 provided in the polyester stock 10 is provided to make it easier for the occupant to place the arm on the armrest portion 12, and the cloth 8 covering the entire surface of the polystock stock 10 is provided to improve the feel and appearance of the polyester stock 10. It is provided in

In particular, as shown in FIGS. 7 and 8, the method of applying the cloth 8 to the polyester stock 10 provided with the spacer recesses 9 is as shown in FIGS. 7 and 8. Adhesive is applied beforehand, and a small hole 15 for air venting is also made. Then, a PVC laminate 16 (commonly known as hotmelt) as an adhesive layer containing ABS resin and a high-temperature adhesive strength enhancer is superimposed on the back side of the cloth 8, and the cloth 8 and the PVC laminate 16 are heated to soften, and then the polyester 10 is bonded. Place it over the small hole 1.
The fabric 8 is brought into close contact with the polyester 10 by suction from 5, and vacuum molding is applied. However, since the adhesion is still insufficient, it is necessary to press the surface of the cloth 8 twice with a press to make the PVC laminate 16 bite into the cloth 8 to further ensure the adhesion between the cloth 8 and the polyester 10. It is. When the cloth 8 is glued to the polyester stock 10 in this way,
The PVC laminate 16 digs into the fabric 8, making it appear as if only the fabric 8 is glued to the polyester 10 (see FIG. 8). In addition, the reason why ABS resin and high-temperature adhesive strength enhancer are mixed into the PVC laminate 16 is to strengthen the adhesive strength of the PVC laminate 16 as an adhesive layer, and if these are not mixed into the PVC laminate 16, the fabric 8 will be This is because the tricot (mesh) has a strong force to return to its original state, and the adhesive strength of the PVC laminate 16 is weakened, causing the fabric 8, especially in the recessed portion 9, to peel off from the polyester 10 and lift up.

<Problems to be Solved by the Invention> However, in the case of such conventional interior parts, in order to provide a covering material such as the cloth 8 on the uneven surface such as the recessed portion 9 as described above, it is necessary to Very expensive ABS resin and PVC mixed with high temperature adhesive strength enhancers
In order to adopt a laminate 16 or to bond the cloth 8 and the polyester 10 more reliably,
Since it was also necessary to press the PVC laminate 16 two more times with a press, the cost was extremely high and the work was troublesome.

This invention was made by paying attention to such conventional technology, and the expensive ABS was used to provide the cover material.
The purpose of the present invention is to provide an interior product that is inexpensive and can be provided with a covering material through simple work without using an adhesive layer such as PVC laminate mixed with a resin or a high-temperature adhesive strength enhancer.

<Means for Solving the Problems> In order to achieve the above object, the interior product according to the present invention is provided with a cloth covering material in which inexpensive heat-sealable fibers are arranged at least on the side facing the interior product. The summary is what was done.

<Function> Since heat-sealable fibers are placed on at least the adhesive side of the cloth cover material, which is the side that corresponds to the interior parts, the cover material itself has extremely strong adhesion and shape-retaining functions. There is no need to use any other adhesive layer such as conventional hot melt, and even if the adhesive surface is uneven, it can be reliably covered by simply pressing the covering material onto the adhesive surface of the interior product while heating it. The material can be attached to the adhesive surface of interior parts.

<Example> The details of this invention will be explained below based on the drawings. Note that the explanation of parts common to the conventional one will be omitted since they are redundant.

FIGS. 1 and 2 are diagrams showing an embodiment of the present invention. The cloth 17 as the "covering material" is made of pile fiber, and its fiber raw materials, the pile yarn (warp) 18 and the ground warp (warp) 19, are a blend of polyester and thermoplastic resin materials such as nylon. In addition to polyester and nylon, the ground weft (weft) 20 contains heat-fusible fibers [for example, "Chitsuso Polypro ES", a polypropylene-based heat-fusible fiber manufactured by Nippon Chitsuso Co., Ltd.
(product name)] is blended at 40%. Therefore, at least a portion of the heat-fusible fibers will be on the side to be bonded, which is the side a corresponding to the interior item. This heat-fusible fiber has high adhesion and shape retention, and has approximately 120%
It melts at ℃ and forms an adhesive layer with remarkable adhesive strength. Therefore, the fabric 17 blended with this heat-fusible fiber is heated to 130°C.
When pressed against the adhesive surface of the interior item while heating, the heat-sealing fibers melt and strongly adhere the fabric weft 20 to the adhesive surface of the interior item, ensuring that the entire fabric 17 is applied to the uneven adhesive surface. However, it can be bonded even when the surface is bonded, and the uneven shape can be maintained even in the bonded state. In addition, the ratio of blending of heat-fused fibers is
A suitable content is 20 to 60%; if it is less than this, the adhesiveness and shape retention will be reduced, and if it is more than this, the ground weft yarn 20 will become weak. Also, the appropriate heating temperature is around 130℃.
If the temperature is lower than 120°C, the heat-fusible fibers will not melt, and if the temperature is too high, the pile yarn 18 and ground warp yarn 19 made of a blend of polyester and nylon will be damaged.

FIGS. 3 and 4 are diagrams showing other embodiments of the present invention. The cloth 21 is of plain weave, and the warp threads 2
Both yarns 2 and weft 23 are made by blending spandex yarn with good elasticity with 30% heat-fusible fiber. Since both the warp yarn 22 and the weft yarn 23 are blended with heat-fusible fibers, they have good adhesion to the adhesion surface of the interior product, and since spandex yarn is used, even if the adhesive surface of the interior product is uneven. We can respond even better.

In addition, in the above explanation, "blending" was shown as an example of how to arrange heat-fusible fibers on cloth facing material, but the method is not limited to this. It may be woven or sewn into a surface, or a nonwoven fabric may be formed using heat-fused fibers as one of the materials, and this nonwoven fabric may be sewn integrally to the surface of the facing material that corresponds to the interior product.

<Effects> Since the interior product according to the present invention has the contents as explained above, the outer covering material itself does not require an adhesive layer such as an expensive ABS resin or PVC laminate mixed with a high-temperature adhesive strength agent. Since it can have an adhesive function, it has the advantage that it is extremely inexpensive and the work of providing the covering material is simple. In addition, heat-fusible fibers have high adhesion and shape retention, so they are particularly suitable for interior products with uneven surfaces, and are extremely versatile and can be employed in a variety of interior products.
