DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
As shown in FIG. 1, a vehicular lining as an example of the present invention, such as a roof lining 1, covers the inside of a roof portion (not shown) of a vehicle body panel. FIG. 1 shows the back side of the roof lining 1 (vehicle body panel side). The roof lining 1 has a duct 9, and includes a roof lining main body 2 and a duct wall 3 that is bonded to the back side of the roof lining main body 2 to form the duct 9.
[0017]
The roof lining body 2 is obtained by molding a flat lining base material 2a (FIG. 4), and has a substantially rectangular shape in plan view. The roof lining body 2 is arranged with its long sides facing the front and rear of the vehicle. The roof lining body 2 is formed with a blowout hole (not shown) for blowing air into the vehicle from the duct 9 constituted by the duct wall 3 bonded to the roof lining body 2. Further, the surface of the roof lining body 2 on the passenger compartment side is covered with a skin material 10 (FIG. 2) such as a nonwoven fabric, a woven fabric, a knitted fabric, or synthetic leather. Here, examples of the lining substrate 2a include a non-breathable substrate such as a laminate of a thermoplastic resin and a thermosetting resin and a foamed sheet, for example, a polypropylene-based foamed sheet or a polyphenylene ether-based foamed sheet.
[0018]
The duct wall portion 3 is formed by forming a flat duct base material 3 a (FIG. 4), and has an adhesive layer of, for example, a hot melt film 12 on the surface to be bonded to the roof lining body 2. Such a duct wall 3 is curved in a convex shape and forms the duct 9. The duct 9 communicates with one long side of the roof lining body 2 and further communicates with, for example, an air conditioner. Here, the duct base material 3a may be any non-breathable base material having an adhesive layer on the surface. For example, the duct base material 3a may be provided with the adhesive layer on the same base material as the lining base material 2a.
[0019]
Further, as shown in FIG. 2, the duct wall 3 is bonded to the roof lining body 2 by the adhesive layer of the hot melt film 12. Here, the hot melt film 12 is an adhesive having a characteristic that it becomes liquid when heated and exhibits fluidity, and returns to the original solid when cooled. Generally, the hot melt film 12 can be bonded quickly and is relatively inexpensive. And there is an advantage such as not containing a solvent. Further, the adhesive layer provided on the duct base material 3a may be composed of, for example, a commonly used adhesive, or may be composed of an adhesive such as a silicon-based adhesive. What is necessary is just to be able to adhere the main body 2 and the duct wall 3.
[0020]
Next, a press mold for forming the roof lining 1 will be described. As shown in FIG. 3, a concave chamber (duct molding concave chamber) 23 for molding the duct wall portion 3 in the lower mold 21 out of the lower mold 21 and the upper mold 22 constituting the press mold. have. In addition, a suction port 24 for sucking air between the duct wall 3 and the lower mold 21 is formed in the concave chamber 23 as described later.
[0021]
Here, the manufacturing method of roof lining 1 is demonstrated with reference to FIG.
First, as shown in FIG. 4A, the duct base material 3 a, the lining base material 2 a, and the skin material 10 are overlapped in this order from the lower mold frame 21 side between the lower mold frame 21 and the upper mold frame 22. Arrange in the state. Here, the duct base material 3a and the lining base material 2a are heated in advance so as to be easily press-formed, and the hot melt film 12 provided on the duct base material 3a is in a molten state.
Next, as shown in FIG. 4 (b), the duct base material 3a and the lining base material 2a are sandwiched from both sides by a press mold and pressed by, for example, a cold press and hot melted by heating. When the melt film 12 is cooled and solidified during cold pressing, the duct base material 3a is bonded to the lining base material 2a. At this time, air is injected from the air injection port 25 between the lining substrate 2a and the duct substrate 3a, and the air between the duct substrate 3a and the lower mold 21 is sucked through the suction port 24. By doing so, the duct base 3 a is deformed into the shape of the concave chamber 23 to form the duct 9. In addition, since the lining base material 2a and the duct base material 3a are non-breathable, air does not leak from the adhesion part of the duct base material 3a and the lining base material 2a. Further, for example, an adhesive layer of a hot melt film 12 is provided on either side of the lining base material 2a and the skin material 10 so as to adhere to each other during press molding.
[0022]
As described above, according to the roof lining 1 which is an example of the vehicle lining according to the present invention, the duct base material 3a constituting the duct 9 is superimposed on the lining base material 2a which is the main body of the roof lining 1. When these are sandwiched from both sides by a press mold (lower mold 21 and upper mold 22) and press molded, and when the duct base 3a is bonded to the lining base 2a, the lining base 2a and the duct base By injecting air between the material 3a and sucking air between the duct base material 3a and the lower mold 21 of the duct base material 3a, the duct base material 3a is deformed to form the duct 9. As a result, it is possible to reduce the number of press molding steps compared to the prior art because a pair of press molds required for molding the lining base material 2a and the duct base material 3a is sufficient. So it can be reduced as compared with the prior art. In addition, the roof lining 1 can be formed by integrally molding the lining substrate 2a and the duct substrate 3a by a single press molding. Moreover, in addition to the air injection between the lining base material 2a and the duct base material 3a, the air suction between the duct base material 3a and the lower mold 21 is performed. The duct 9 can be formed by deformation.
[0023]
In the above embodiment, the roof lining 1 is used. However, the present invention is not limited to this, and the present invention can be applied to other roof lining, door lining, side lining, and the like.
Of course, the material and shape of the roof lining body 2 and the duct wall 3, the adhesive layer, and other specific detailed structures can be variously changed without departing from the gist thereof.
In addition, the shape of the roof lining 1, the material of the cover material, and the like are arbitrary, and it is needless to say that the specific detailed structure and the like can be appropriately changed. Further, the drawings are only schematically shown so that the invention can be understood, and the invention is not limited to the illustrated examples.
Further, when forming the duct 9, air is injected from the air inlet 25 between the lining base material 2a and the duct base material 3a, and the air between the duct base material 3a and the lower mold 21 is sucked. Although the example which deform | transforms the duct base material 3a into the shape of the concave chamber 23 by attracting | sucking via the opening | mouth 24 was demonstrated, not only this but the air between the duct base material 3a and the lower mold frame 21 is attracted | sucked The duct base material 3 a may be deformed into the shape of the concave chamber 23 only by suction through the mouth 24.
[0024]
