Description

[Detailed Description of the Invention] <<Technical Field of the Invention>> This invention relates to an automobile door trim, and particularly relates to an improvement of the armrest portion thereof.

<<Prior art and its problems>> FIG. 1 shows a state in which a conventional general automobile door trim 1 using a flat core material is attached to a door inner panel 2. Door trim body 5 made by welding a skin material 4 to the surface of a flat core material 3 such as hardboard.
and an armrest 9, which is formed by injecting and foaming a pad material 7 into a molded skin material 6 and inserting a core material 8, are constructed separately.
0 and the weather strip 11 are attached to the door inner panel 2, and then the armrest 9 is attached with the screw 1.
2, the cap 13 is fixed to the door inner panel 2, and finally the cap 13 is fitted into the mounting hole of the armrest 9 to form the door trim 1.

However, in such a conventional configuration, since the armrest 9 is formed separately, there is no sense of unity or continuity with the door trim body 5, and furthermore, the door trim body 5 is a flat plate,
Since the armrest 9, which can be seen as a separate body at first glance, is attached to this, a sufficient sense of unity cannot be obtained, and the quality of the appearance is therefore poor.

In addition, in order to obtain sufficient three-dimensionality and a sense of unity for use in some luxury cars, integrally molded door trims are provided in which the door trim body and armrest parts are integrally formed by vacuum molding or foam molding of resin. However, this product is extremely expensive compared to the above-mentioned one using hardboard, and the same skin material must be used for the door trim body and the armrest, and the armrest is made of the same material. To give a soft feel,
It is not possible to use a different skin material, such as cloth, in this part, and there is a problem in that the feel of the armrest part is poor.

《Purpose of the invention》 This invention was made in view of the above-mentioned drawbacks of the conventional technology, and the purpose of the invention is to:
A sense of unity between the door trim body and the armrest,
To provide a door trim for an automobile that has a sense of continuity, is inexpensive, has a sufficient three-dimensional effect, and can use a skin material of a different specification only for the armrest part.

《Structure and Effects of the Invention》 In order to achieve the above object, the present invention laminates a skin material on the surface of a flat core material, and places a resin molded body at an appropriate position on the surface of the door trim body which is integrated by welding. In a door trim for an automobile, the resin molded body is fixed to the surface of the core material on the side of the door trim body, and the armrest skin material is covered with resin. It is arranged so as to extend outward from the periphery of the back surface of the molded body, and the peripheral edge end of this armrest skin material and the skin material on the side of the door trim body are integrated with the surface of the core material on the side of the door trim body by welding. It is characterized by

That is, according to this invention, the armrest skin material is arranged on the door trim main body side in a state extending outward from the back surface periphery of the resin molded body (core material of the armrest), and is placed on the side of the door trim main body to form a separation between the door trim main body and the armrest. The wire is covered by the armrest skin material, and the outer peripheral end of the armrest skin material is welded to the core material of the door trim body together with the skin material on the door trim side, so the sense of unity and continuity between the door trim body and the armrest is achieved. Even if the core material of the door trim is made of a flat material, there is an advantage in that it is possible to provide an extremely excellent automobile door trim with a sufficiently three-dimensional appearance and an excellent external design.

Moreover, unlike integrally molded door trims, the skin material of the present invention is not limited; for example, a skin material with excellent feel and feel can be used only in the armrest area, allowing for various variations. , and can be produced at a much lower cost than integrally molded door trims.

<<Description of Embodiment>> Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

FIG. 2 shows a state in which an automobile door trim 21 according to the present invention is attached to a door inner panel 22. This door trim 21 has a door trim body 2 whose core material 23 is a flat material such as hardboard
4, and an armrest 25 provided on the side surface of the door trim body 24 over substantially its entire length as shown in FIG.

The door trim body 24 has a garnish 26 fixed to the upper edge of the core material 23 by a metal stitcher M, and the entire surface except for the armrest 25 portion is covered with a skin material 27. For example, a low melting point urethane foam 28 for welding is laminated with a vinyl chloride sheet 29, or a separate laminated product, or especially at the lower edge, a carpet 30 is used, and this is used as the armrest 25 as described below.
At the same time, a welder 31 is welded to the core material 23.

The armrest 25 is constructed by pasting an armrest skin material 33 on the surface of a resin molded body 32 obtained by injection molding or the like as its core material, and the resin molded body 32 has, on the outer periphery of the back surface, It has a locking pawl 34 that engages with the core material 23 of the door trim body 24, and a boss portion 36 that penetrates the core material 23 and is directly fixed to the door inner panel 22 with a screw 35.

Further, the armrest skin material 33 is made of, for example, a low melting point urethane foam 37 for welding and a fabric skin layer 38 of nylon or the like laminated thereon, and is adhered to the surface portion of the resin molded body 32. At the time of this attachment, the armrest skin material 33 is cut to be one size larger than the outer peripheral edge of the resin molded body 32 and extends outward from the back surface peripheral edge of the resin molded body 32. Then, with the resin molded body 32 attached to the core material 23 of the door trim body 24 by the locking claws 34, the skin material 27 of the door trim body side is superimposed on the upper surface of the outer periphery of the armrest skin material 33. At the same time as welding the entire skin material 27, both skin materials 2
Welder welding 31 to the surface of core material 23 for both 7 and 33
It has been a.

During this weld welding, as shown in FIG. 4, the overlapping skin materials 27, 3 are
3 is cut off, and its excess portion is removed, so that both skin materials 27 and 33 are constructed as if they were continuous.

In Fig. 2, 41 indicates the door window glass, 42 indicates the weather strip, and 4
3 is a cap that is attached to the opening of the boss portion 36 of the armrest 25 after the door trim 21 is attached to the door inner panel 22 and the screws 35 are tightened, and this cap 43 is also made of the same material as the armrest skin material 33. Decorated.

Therefore, according to the above configuration, the armrest 25
A sense of unity and continuity can be obtained between the door trim body 24 and the flat door trim body 24, and there is no sense of discomfort as if only the armrest was attached as in the past, and the appearance quality has been greatly improved. Material 23
Since a flat plate material such as a hardboard is sufficient without using a molded product, it can be manufactured at an extremely low cost.

Further, unlike an integrally molded door trim, the armrest skin material 33 for the armrest 25 portion can be freely selected, and if it is made of cloth as described above, the appearance quality and feel will be greatly improved. Further, instead of fabric, a carpet material made by planting piles on a resin sheet by electrostatic flocking may be used, and furthermore, the skin material 27 of the door trim body 24 and the skin material 33 for the armrest may be made of the same material. Of course, this is also possible.
