Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automobile door trim, and more particularly to an automobile door trim having an improved appearance design at a joint between a rear edge of a door trim and an inner panel.

《Prior art and its problems》 Recently, in order to improve the habitability in the vehicle interior, the material of interior parts such as door trims for automobiles is upgraded, or a single skin material is not used. By using a composite skin material in which sheets of different materials such as resin sheets, cloths, and carpets are joined together, the appearance and design is improved.

5 and 6 show a front view and a partial sectional view of a conventional automobile door trim. A conventional automobile door trim 1 has a core material 2 formed into a required shape and a skin material 3 on the surface thereof.
As the skin material 3, different materials having different surface appearances and surface textures, that is, a foamed vinyl chloride sheet 4 and a cloth 5 are bonded.

The two are joined by a sewing process, and in order to make the sewing line inconspicuous to the outside, a groove portion 6 is formed in the core material 2 along the joining line. The sewn portion with 5 is fixed with wood grain.

<< Problems to be Solved by the Invention >> Thus, in the conventional vehicle door trim 1, the groove portion 6 is formed along the joining line between the foamed vinyl chloride sheet 4 and the cloth 5 from the front upper end portion to the rear side edge of the door trim 1. It extends to the portion, and in particular, the rear edge of the vehicle door trim 1 and the inner panel 7 have a plow, which is very unattractive (see FIG. 7).

Further, when the groove portion 6 is set up to the rear end portion of the door trim 1, the bottom portion of the groove portion 6 abuts the inner panel 7, so that the rear end edge of the door trim 1 other than this groove portion 6 is in a state of protruding to the indoor side. It has also been pointed out that a clearance cannot be set between the mating part and it interferes with the mating part.

Therefore, the object of the present invention is to improve the appearance of an automobile door trim in which sheets of different materials are joined as a skin material to improve the appearance and design, and particularly, the appearance is improved at the rear side edge portion and the mating component It is to provide an automobile door trim that enables setting a sufficient clearance with.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a skin in which a core material formed into a required shape and sheets of different materials that are attached to the surface side of the core material are joined together. In a vehicle door trim made of a material, the sheet of the different material has a portion corresponding to the rear end edge of the door trim as a welded joint and is integrated by welding, and the other joints are sewn joints. As an integral feature of the present invention, the sewn joint of the sheet is grained in the groove formed in the core material while the weld joint of the sheet is arranged on the surface of the flat portion of the core material. .

<Operation> As is clear from the above configuration, the sheets of different materials are
A welded joint corresponding to the rear end portion of the door trim and a sewn joint corresponding to the other general portion are provided, and the sewn joint is housed in the wood grain groove of the core material, is not conspicuous to the outside, and is further welded. Is located on the flat surface of the core material, and the groove is not set up to the rear end of the door trim, so there is no gap between the inner panel and the rear edge of the door trim, and this part looks good. It will be extremely good.

Further, since the rear end edge of the door trim is fixed to the inner panel in a state of being almost in close contact with the inner panel, a clearance with the counterpart component can be maintained and interference with the counterpart component can be prevented.

<< Embodiment >> An embodiment of an automobile door trim according to the present invention will be described in detail below with reference to the accompanying drawings.

1 to 3 are front views and respective cross-sectional views of an automobile door trim, and FIG. 4 is a cross-sectional view showing a procedure for joining sheets of different kinds of materials constituting a skin material.

In the drawings, a door trim 10 includes a core material 11 such as a wood fiber board hot-press molded into a required shape or a thermoplastic composite resin plate cold-press molded into a required shape, and an integrally attached surface side of the core material 11. It is generally composed of a skin material 12 to be worn.

The skin material 12 is formed by joining sheets of different materials having different surface appearances and surface feels. That is, in this example, foamed vinyl chloride 13 and cloth 14 such as velvet, jersey, tricot, and moquette.
The joining line (boundary line) between the seats 13 and 14 is set to a line that draws a gentle curve from the front upper end of the door trim 10 to the rear end central portion.

Further, the joint structure of the foamed vinyl chloride 13 and the cloth 14 is such that only a part of the rear end side of the door trim 10 is welded to both seats 1.
A welder joint portion 15 in which 3, 14 are joined is set, and a sewn joint portion 16 in which both sheets 13 and 14 are joined by sewing is provided in the other portion. .

On the other hand, the shape of the welded joint portion 15 or the sewing joint portion 16 provided on the skin material 12 on the side of the core material 11 is not so good in appearance of the stitched joint portion 16, so that the groove portion 17 is formed in the core material 11. The sewing joint 16 is fixed in the groove 17 with wood grain, and the groove 17 is not set in the portion corresponding to the welder joint 15, and the flat portion 18 of the core 11 is arranged. .

Therefore, as shown in FIG. 2, the sewn joint portion 16 between the foamed vinyl chloride 13 and the cloth 14 is housed in the groove portion 17 so that the sewn portion is not conspicuous to the outside, and as shown in FIG. Welding joint 15 between expanded PVC 13 and cloth 14 on flat portion 18
Since the groove is not formed on the rear end edge of the automobile door trim 10 as in the past because it is attached, it is attached and fixed in a state in which it is in close contact with the inner panel (not shown), and there is no gap between the two. Since the welder joint portion 15 attached to the flat portion 18 has a sharp joint line, the appearance of the rear edge portion of the automobile door trim 10 is significantly improved, and the welded portion 15 interferes with a mating component at this portion. Conventional problems can be effectively resolved.

For reference, the welder joint 15 between the foamed PVC 13 and the cloth 14
As shown in FIG. 4 regarding the method of forming the, the high-frequency welder-weldable PVC sheet 19 is laminated on the back surface of the cloth 14, and the welder bar 20 is used to form the PVC foam 13 and the PVC.
The welding portion 15 in the skin material 12 can be easily formed by pressing the lap portion 21 with the cloth 14 backing the sheet to supply electricity.

In this example, the foamed vinyl chloride 13 and the cloth 14 are used as the different materials forming the skin material 12, but the material is not particularly limited as long as the material can be welded to the welder.

<Effects> As is clear from the above description, in the automobile door trim according to the present invention, a composite skin material in which sheets of different materials such as foamed vinyl chloride and cloth are joined is used as the skin material, and the appearance design is improved. A door trim for an automobile, which has improved performance, in which the groove formed along the joining line of the skin material does not extend to the rear end of the door trim, but the rear edge of the door trim is flat, Since the welder joint with the line is set, the rear edge of the automobile door trim is made flat without deteriorating the aesthetics of the joint, eliminating the gap between the inner panel and the automobile door trim. This has the effect of significantly improving the appearance of the rear edge and improving the appearance and design of the door trim.

Furthermore, since the rear edge of the automobile door trim is attached to the inner panel almost in close contact, sufficient clearance can be secured between the inner panel and the mating parts, and interference with the mating parts can be prevented. is there.
