[Detailed description of the invention]

[0001]

The present invention relates to an automobile door interior material which can secure the strength at the opening of the pocket bulging portion of the interior material body and can prevent peeling of the skin material end. It is about.

[0002]

2. Description of the Related Art Door interior materials for automobiles in which a skin material is adhered to the surface of an interior material body having a pocket-shaped bulging portion are widely known.

However, such door interior materials for automobiles have a problem in that the edges and openings are not sufficiently strong, so that they may be deformed or damaged during use. There is also a problem that the end of the skin material is peeled off at the opening. Therefore, an automotive interior material that solves these problems by fitting a reinforcing member such as a metal molding into the periphery of the opening is disclosed in, for example, Japanese Utility Model Laid-Open No. 62-140827. No. 63-79222, which has been previously proposed, but in this case, a separate processing step for fitting the reinforcing member is required, and the cost is high. There was another problem that the feel was poor.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and ensures the strength at the opening of the pocket-shaped bulging portion of the interior material body and ensures the peeling of the end of the skin material. It has been completed with the objective of providing an automotive door interior material that can be prevented at the same time, has an excellent touch feeling in the opening, and is also excellent in productivity and can be produced at low cost. Things.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an automobile door interior material according to the present invention is an automobile door interior material having a pocket-shaped bulging portion and a surface material adhered to the surface of the interior. In the door interior material, the end of the skin material adhered to the surface of the pocket-shaped bulging portion is wound behind the opening of the pocket-shaped bulging portion, and the wrapped edge is formed in a pocket shape from the surface of the end portion. It is characterized by being covered with a protective film layer of a hot-melt adhesive coated over the back surface of the bulging portion.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. In the drawing, reference numeral 1 denotes a three-dimensionally shaped interior material main body forming an interior material of an automobile door, 2 denotes a pocket-shaped bulge formed on the interior side of the interior material main body 1, and 3 denotes a pocket-shaped bulge. An opening 4 formed in the upper part of the portion 2 is a skin material adhered to the surfaces of the interior material main body 1 and the pocket-shaped bulging portion 2, 5.
Is an end of the skin material 4 which is wound around and adhered to the back side of the opening 3 of the pocket-shaped bulging portion 2.

The end 5 of the skin material 4 wrapped around and adhered to the back side of the opening 3 of the pocket-shaped bulging portion 2 is further coated with hot melt from the surface to the back surface of the pocket-shaped bulging portion 2. It is covered with a protective film layer 6 of a mold adhesive and is firmly fixed to the surface of the interior material main body 1. As the protective film layer 6 of the hot melt adhesive, for example, a melt thermoplastic synthetic resin adhesive having a melt viscosity property of about 10,000 cps such as a polyester resin or a urethane-based moisture-curable resin is used. About 20 depending on the gun
It is heated and melted at 0 ° C. and coated from the surface of the end portion 5 to the back surface of the pocket-shaped bulging portion 2, and has a width of 10 to 15 m.
m, and is formed on a protective film layer 6 having a thickness of about 1.5 to 2.5 mm.

A glass fiber material, a rayon fiber material, a thermosetting synthetic resin, or the like may be appropriately mixed into the material of the protective film layer 6 in accordance with the purpose of improving the strength and the feeling of touch. As shown in FIG. 3, a core material 7 made of a metal wire or the like is placed in advance of the winding edge of the end portion 5 of the skin material 4 and then covered with a protective film layer 6 to increase the strength. You can also.

[0009]

In the above-described construction, the opening 3 has the end 5 of the skin material 4 extending to the back side of the pocket-shaped bulging portion 2.
Not only is rolled up and adhered, but also the rolled edge of the end 5 is covered with a protective film layer 6 of a hot melt type adhesive coated from the surface of the end 5 to the back of the pocket-shaped bulging portion 2. Since it is covered and fixed, there is no reinforcing member made of a separate member at the peripheral portion of the opening 3 as in the conventional case, so that the design is excellent and the touch feeling is also preferable. Maintains sufficient strength in the opening portion 3 by the protective film layer 6 covering from the surface of the end portion 5 to the back surface of the pocket-shaped bulging portion 2 without the conventional reinforcing member made of a separate member. And peeling of the end portion 5 of the skin material 4 can be reliably prevented.

When the thickness or shape of the protective film layer 6 is varied by using a material obtained by mixing a glass fiber material or the like in a hot-melt type adhesive as the material of the protective film layer 6, the strength is further improved and the touch is improved. In particular, as shown in FIG. 3, a core material 7 such as a metal wire is disposed in front of the winding edge of the end 5 of the skin material 4 as shown in FIG. In the case where is formed, the strength can be greatly increased. Further, the coating of the protective film layer 6 can be easily performed by a usual coating gun, and exhibits excellent productivity without requiring a special processing step for fitting a reinforcing member as in the related art. And in particular,
When a hot-melt type adhesive having the above-mentioned predetermined viscosity characteristics is used as the material of the protective film layer 6, efficient production can be achieved without problems such as dripping after the coating process.

[0011]

As is apparent from the above description, the present invention ensures the strength at the opening of the pocket-shaped bulging portion of the interior material body and ensures that the wrapping edge of the skin material at the opening is peeled off. It has excellent touch feeling in the opening, and it has a very simple structure that can greatly expand the degree of freedom of design, and it is also excellent in formability and inexpensive. It can be produced.

Accordingly, the present invention has a very high practical value as a solution to the problems of the conventional door interior materials of this kind.
