BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspended ceiling material for automobiles.

[0002]

2. Description of the Related Art As a suspension ceiling material for an automobile of this type, vinyl leather has been mainly sewn or welded, but it is inferior in terms of appearance and feel. For this reason, in recent years, Japanese Utility Model Publication No. 56-29264 and Japanese Utility Model Publication No. 5
As can be seen in Japanese Patent Publication No. 8-6780, cloth sewn with a good appearance and feel is also used. However, a suspended ceiling material for automobiles made of cloth is a seam stitched at a linear joint portion of the cloth with a sewing machine. Since the air inside the vehicle is contaminated by dirt, the seam stains the seams, and in particular, a bag-like portion for inserting the hanging member is provided on the back side of the linear joint as shown in the above-mentioned utility model publication. In the formed product, when the tension is applied to the linear joint and air is easily circulated to the back side, the seams are heavily soiled and the aesthetic appearance is impaired in a short period of time. .

As a solution to such a problem, Japanese Utility Model Laid-Open No. 59-35168 discloses a hot-melt material in which a fabric type interior material is bent from a folding curve to the back side and is interposed between the butting portions. A suspended ceiling material for automobiles has been proposed in which a suspended ceiling material body having a linear pattern portion on the surface is joined by a heat-sealable thin sealing strip material such as When an attempt is made to produce a pile fabric with innumerable loops, which is good and has excellent decorative properties, as an interior fabric, the texture will appear in the linear pattern and the melted thin band of heat-sealable sealing material will be produced. However, since it remains in the naruna and the appearance is damaged, it has been said that when a pile fabric having numerous naruna is used as the interior fabric, it cannot be joined by a heat-sealable thin seal strip.

[0004]

[Problems to be Solved by the Invention] The problem to be solved by the present invention is to solve the above-mentioned problems by providing a pile fabric having innumerable loops that is exceptionally good in touch and excellent in decorativeness. Even if a bag-shaped portion for inserting a hanging member is formed on the back side of a linear joint as an interior material, it is intended to provide an inexpensive suspended ceiling material for an automobile that does not impair the appearance in a short period of time. It is in.

[0005]

A suspension ceiling material for an automobile according to the present invention, which has solved the above-mentioned problems, is a heat-sealing material in which an interior cloth is bent from a folding curve to a back side and interposed between butting portions thereof. In the interior material for automobiles, which is a suspended ceiling material body having a linear pattern portion on the surface joined by a thin sealing strip material, the interior material is a plastic-based non-woven fabric on the back surface of a pile fabric having innumerable loops. It is characterized in that the breathable thin film is layered so that the folding curve is made substantially orthogonal to the weaving direction of the pile forming yarn of the pile fabric.

[0006]

[Operation] Such a suspended ceiling material for automobiles is similar to a conventional suspended ceiling material for automobiles of this type, in which a suspended wire material is inserted into a bag-like portion for inserting the suspension member on the back side of the suspended ceiling material body. When used as a product, the surface is a pile fabric with innumerable loops, so it has excellent feel and decorativeness. Moreover, the linear pattern on the surface has no perforations, and the plastic material on the back of the pile fabric is used. Since the non-breathable thin film of the system does not allow the postscript that is dirty inside the vehicle to circulate to the back side, the stain is significantly reduced even after long-term use. Since the fold curve for forming the mating portion is assumed to be substantially orthogonal to the weaving direction of the pile forming yarn of the pile fabric, the surface of the linear pattern located at the base of the wanna appears or the thin seal strip material The stripping residue may remain in Rana The finish of the linear pattern portion is extremely good, and it is possible to completely eliminate the defective finish of the joint portion, which has been the biggest problem of the product in which the pile fabrics are joined.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described based on the illustrated embodiments. Reference numeral 1 denotes an interior fabric made of a pile fabric having innumerable loops knitted with polyester fibers, polyamide fibers and other arbitrary fibers, and the pile fabric as the interior fabric 1 is a weaving direction of the pile forming yarns 2. A suspended ceiling material main body 5 having a linear pattern portion 4 on the front side is joined at the abutting portions 3 and 3 that are bent to the back side from a folding curve substantially orthogonal to is doing. 6 is a plastic-based non-breathable thin film that is layered on the back surface of the pile fabric to block the breathability without impairing the feel of the surface of the pile fabric and to limit the stretch of the pile fabric, The non-breathable thin film 6 is formed on the back surface of the pile fabric which is the inner cloth 1 by means of a film joining method or a coating film forming method. Reference numeral 7 denotes a heat-sealing thin seal strip material interposed between the butting portions 3 and 3 of the pile fabric which is the interior cloth 1. The thin seal strip material 7 shown in the figure has a wall thickness of 0.3 to
It is made of a low melting point material such as a hot-melt sheet made of a 1 mm ethylene-vinyl acetate copolymer or a thermoplastic resin material such as a polyvinyl chloride sheet.

Reference numeral 8 denotes a bag-like portion formed on the back side of the suspended ceiling material main body 5 for inserting a hanging member, and the bag-like portion 8 forms a linear joint portion of the pile fabric as the interior cloth 1. Therefore, the abutting portions 3 and 3 are located at the base of the bag-shaped portion 8 and are formed by a portion bent to the back side. In addition,
Even if the bag-like portion 8 is formed by taking a tack in the middle of the pile fabric as in the first embodiment shown in FIG. 1, two piles are provided as in the second embodiment shown in FIG. The edge portion of the ground may be the welded portion 9, and the bag-shaped portion 8 may be formed between the welded portion 9 and the linear joint portion forming the linear pattern portion 4.

With the above construction, the interior material main body 5 is a pile material having a looper on the surface, which is bent from the folding curve to the back side and interposed between the butting portions 3 and 3 of a heat-fusible property. A linear pattern portion 4 is formed on the surface by joining with a thin seal strip material 7.
Since it is formed, the appearance and feel are better than those of conventional vinyl leather fabrics, and the linear pattern part 4 is also better than that of general febric interior fabric sewn on. It appears beautifully.

In particular, the important point of the present invention is that the pile forming yarn 2 of the pile fabric 1 has a folding curve for forming the abutting portions 3 and 3 despite the fact that the surface of the pile fabric is formed with loops. By making it almost orthogonal to the weaving direction of the wrinkle, the linear pattern part 4 located at the base of the wanna does not show the surface of the skin and the stripping residue of the thin seal strip material 7 does not remain in the wanna and is linear. This is a point that the finish of the pattern portion 4 is improved, and it is possible to completely eliminate the defective finish of the joint portion which has been the biggest problem of the product in which the pile fabrics are joined.

The linear pattern portion 4 is formed by the butting portion 3,
3 is joined by the thin seal strip 7 so that the seams such as the sewing machine are not present and the appearance is very good, and the dirty interior air flows through the linear pattern portion 4 to the back side to form a linear shape. The area around the pattern portion 4 does not get dirty.

Further, since the plastic-based non-breathable thin film 6 is layered on the back surface of the pile fabric, the dirty interior air does not flow to the back side through the cloth of the pile fabric, and the dirty interior air is generated. The dirt on the surface of the pile fabric is reduced, and the plastic-type non-breathable thin film 6 has the effect of limiting the expansion of the pile fabric that is the interior fabric 1 and increasing the strength, and the abutting portions 3 and 3 are made of plastic. Since they are the same non-breathable thin film of the system, they also exert the effect of increasing the bonding strength with the heat sealable thin seal strip 7.

In order to manufacture such an automobile interior material, however, as shown in FIG. 3, a pile fabric which is an interior cloth 1 cut into a required size and superposed so that the surfaces thereof face each other is used. Between the tooth tips of the pair of weld dies 11, 11 are set so that the weaving direction of the pile forming yarn 2 of the pile cloth is substantially orthogonal to the longitudinal direction of the tooth tips of the weld dies 11, and A heat-sealing thin sealing strip 7 extends between the buttresses 3 and 3 of the interior fabric 1, 1 between the tooth tips, and one side edge of the thinly sealing strip 7 projects from the buttresses 3 and 3 to the front side. The side edge portions are interposed between the abutting portions 3, 3 so as to project inside the bag-shaped portion 8, and then the abutting portions 3, 3 are welded together as shown in FIG. By sandwiching the thin sealing strips 7 by sandwiching between them, the abutting portions 3 and 3 are joined together, As shown in FIG. 5 later, from the pile fabric having the linear pattern portion 4 on the surface by stripping off the protruding portion 7a of the remaining thin seal strip 7 protruding from the abutting portions 3 and 3 to the surface side. Since it can be formed on the suspended ceiling material body 5, the joint strength can be increased and mass production is extremely easy and can be provided at a low cost.

[0014]

[Effect of the Invention] As is apparent from the above description, the present invention is as follows.
Even if a pile fabric with innumerable loops that is exceptionally good in touch and has excellent decorative properties is used as the interior fabric, the flow of dirty air is completely cut off, so linear joining occurs due to the flow of air. When the folding curve is set as the weaving direction of the pile forming yarn, the folding line is made substantially orthogonal to the weaving direction of the pile forming yarn in the pile fabric. The exposed surface of the striped pattern and the stripping of the thin sealing strips left on the wrapping cloth are eliminated, resulting in a very good finish of the linear pattern portion, and the pile fabric as an interior fabric is made of non-air-permeable plastic material. By layering a conductive thin film, the problem of strength of the interior fabric font and its joint portion can be solved, and in combination with the advantage that mass production is easy and it can be provided at low cost, it has an extremely large practical value.
