BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door trim capable of reliably preventing generation of noise from the door when the door is opened / closed or while traveling.

[0002]

2. Description of the Related Art Conventionally, as a door trim for an automobile, as shown in FIG. 5, a cover material 12 is wound on a surface of a base material 11 with its peripheral edge being wound on a back surface of the base material 11 as a winding end portion 14. Although the ones worn are widely used,
Since the skin layer 13 of the skin material 12 wound on the back surface is in direct contact with the body panel 20, there is a phenomenon that an abnormal noise is generated from the door when the door is opened / closed or while traveling.

Therefore, for example, as disclosed in Japanese Utility Model Laid-Open No. 55-87811, a cushioning material made of a foaming resin or the like is interposed between the skin material and the body panel to prevent generation of abnormal noise. However, there is a problem that it is troublesome to mount the cushioning material and the assembling work is complicated, and there is also a problem that the cost is increased because it is necessary to prepare a cushioning material separately. It was

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and can reliably prevent the generation of noise from the door when the door is opened / closed or while the vehicle is running. The present invention has been completed with the object of providing a door trim for an automobile, which can be easily assembled and can exhibit excellent productivity without using a special member and can be manufactured at a low cost. .

[0005]

In the automobile door trim of the present invention made in order to solve the above-mentioned problems, a skin material is wound on the surface of a base material and its peripheral edge is wound on the back surface of the base material as an end portion. In an automobile door trim that is mounted in a state, the skin material is a laminated skin material in which a pad layer is laminated to a skin layer, and the surface of the surface that comes into contact with the body panel is wound on the back surface of the base material as a laminated skin material. Part of the epidermis layer
It is characterized by being formed on the exposed pad surface where a part of the pad layer is exposed after peeling and removal .

[0006]

In this structure, since the contact portion of the wound-in end portion of the skin material with the body panel is the pad exposed surface of the pad layer laminated on the skin layer,
It is possible to prevent the body panel from directly hitting the skin layer as in the conventional case, and it is possible to reliably prevent the generation of abnormal noise due to the cushioning action of the pad layer made of the foaming resin.

[0007]

The present invention will now be described in detail with reference to the illustrated embodiments. In the figure, 1 is a base material for an automobile door trim, 2 is a front surface of the base material 1, and a peripheral edge thereof is wound around a back surface of the base material 1 to form an end portion 5.
It is a skin material that is covered in the state of being caught.
The skin material 2 is a laminated skin material in which a pad layer 3 made of a foaming resin such as a polypropylene foam layer is laminated and integrated on the back surface of a skin layer 4 such as a vinyl chloride resin sheet.

In the present invention, a part of the pad layer 3 is exposed as a pad exposed surface 6 on the surface of the wound-in end portion 5 of the skin material 2 which is in contact with the body panel 10. There are features. That is, the first shown in FIG.
In this embodiment, a convex portion 1a is formed on the lower portion of the contact surface side of the base material 1 with the body panel 10, and a part of the winding end portion 5 protrudes corresponding to the convex portion 1a, and The skin layer 4 of the protruding portion is peeled and removed to form the exposed surface 6 of the pad layer 3, which is a contact portion with the body panel 10. As a result, the body panel 10 comes into direct contact with the elastic pad layer 3, so that the phenomenon of noise generation is eliminated and the sealing property between the two is increased.

As shown in FIG. 2, such an automobile door trim can be easily produced by an ordinary vacuum forming die without problems such as draft and the like. The skin layer 4 of the protruding portion may be peeled and removed by slicing or the like, and then folded back to end-process the peripheral portion of the base material. In addition, as shown in FIG. 3, the base material 1 is formed in a flat plate shape and a protruding portion is formed only on the winding end 4 side, and the skin layer 4 of the protruding portion is peeled off to remove the pad layer 3. Exposed surface 6 and body panel 1
You may make it a contact part with 0. In addition, as shown in FIG. 4, a vehicle door trim similar to the conventional one is molded, and the winding end 5 of the skin material 2 is doubled on the back surface side of the base material 1 so that the skin layers 4 and 4 are in close contact with each other. It is also possible to fold it back to expose the pad layer 3 at the end as the exposed surface 6.

In such a structure, the skin material 2 is attached in a state in which the skin material 2 is folded back at the peripheral portion of the base material 1 and rolled up to the back surface side, like the conventional door trim for an automobile of this kind. However, the skin material 2 is used as a laminated skin material in which the pad layer 3 is laminated on the skin layer 4, and the pad layer 3 of the pad layer 3 is formed on the surface of the winding end 5 wound on the back surface of the base material 1 in contact with the body panel. Since a part is exposed as the pad exposed surface 6, it is possible to prevent the body panel 10 from directly hitting the skin layer 4 of the wound-in end portion 5 of the skin material 2 as in the conventional case, and it is made of a foaming resin. It is possible to reliably prevent abnormal noise from being generated by the cushioning action of the pad layer 3 having elasticity. Further, the sealing property between the two is improved, and a higher quality automobile door trim can be provided. Moreover, skin material and body panel 1
Unlike the one in which a cushioning material made of a foaming resin or the like is additionally interposed between 0 and 0 to prevent the generation of abnormal noise, the pad layer of the laminated skin material is effectively used. There is an advantage that the cost can be reduced because it is unnecessary.

[0011]

As is apparent from the above description, the present invention can reliably prevent the generation of noise from the door when the door is opened / closed or while the vehicle is running, and a special member can be used. Therefore, the assembling work can be easily performed, excellent productivity can be exhibited, and the production cost can be reduced. Therefore, the present invention has an extremely great contribution to the development of industry as an automobile door trim that eliminates the conventional problems.
