Abstract

PURPOSE:To improve appearance, by eliminating a gap on a mounted surface for the inner panel of a door, and eliminating a level difference at a side edge. CONSTITUTION:A tension member 10 is conjoined to the side edge portion of a thick outside material 4 by high-frequency welding 11. The tension member 10 and the thick outside material 4 are pushed and deformed onto the surface of a core material 1 at the location of the high-frequency welding 11. The tension member 10 is bent back and stuck to the back of the core material 1 as the tension member extends outwards from the location of the high-frequency welding, due to the thickness of a padding material 2, so that the thick outside material 4 is fixed on the surface of the core material 1. Since the thickness of the tension member 10 is equal to that of a thin outside malterial 3, the thickness of the tension member is equal to that of a side edge projection end and a back wrapping end. When a door trim of such construction is fitted on the inner panel of a door, a continuous outline corresponding to the outline of the core material 1 is provided.

Description

Detailed Description of the Invention (Field of the Invention) This invention relates to an automobile door trim in which a thick skin material such as cloth or carpet is pasted together with a thin skin material such as vinyl chloride. Regarding processing.

(Prior art and its problems) Door trims used in relatively high-end passenger cars include a thin skin material made of vinyl chloride, which is commonly used, and a thick skin material such as fabric or carpet that is laminated to provide decorative properties. We are trying to further improve this.

FIG. 1 shows an example of the door trim, in which a thin skin material 3 made of a vinyl chloride sheet is adhered to the surface of the core material 1 via a pad material 2, and is surrounded by this skin material 3. A thick skin material 4 made of cloth is adhered to the covered part.

The peripheral edge of the thin skin material 3 is folded back and adhered to the back surface of the core material 1.

Further, one end portion of the thick skin material 4 reaches one side edge of the core material 1, and this portion is folded back and adhered to the back surface of the core material 1 in the same manner as the thin skin material 3 described above.

FIGS. 2(a) and 2(b) show the cross-sectional shape of the folded end.

The thickness a of the part where the thin skin material 3 is attached is the same as that of the thick skin material 4.
It is definitely smaller than the thickness b. Further, when comparing the protrusions la- and b- from the side edges of the core material 1, the amount of protrusion of the thick skin material 4 is larger.

Therefore, when this door trim is attached to the door inner panel, if the side edge is positioned exactly at the opening/closing end of the door, a gap will be formed corresponding to the difference in thickness between the two skin panels. Moreover, since the amount of protrusion from the core material is large, the level difference becomes noticeable, which also causes a poor appearance.

(Objective of the Invention) The present invention eliminates the gap between the door inner panel and the side edge of the door trim in which skin materials of different thicknesses are bonded together, thereby improving the appearance. The purpose of writing is to write something new.

(Structure and Effect of the Invention) In order to achieve the above object, in the present invention, a tension horn sheet having the same thickness as the thin skin material is joined to the winding end side of the W-hand skin material, and the tension sheet is It is characterized by being folded back and pasted on the back side of the core material together with the skin material.

According to the above configuration, the thickness J3 of the back folded edge and the amount of protrusion from the side edge are exactly the same, so when this door trim is attached to the inner panel, there will be no gap on the mounting surface, and the side edge will be completely fixed. Since there are no uneven edges, the appearance of one door and one rim can be improved.

(Description of Embodiment) FIGS. 3a3 and 4 show a first embodiment of the present invention.

Note that the same reference numerals are given to the same parts as in the prior art, and the explanation thereof will be omitted.

A tension member 10 is joined to the side edge end of the thick skin material 4 by high frequency welding 11.

Then, the high-frequency welding 11 portion is in a state of being crushed by the surface of the core material 1, and by once rising from this portion due to the thickness of the pad material 2, the tension member 10 is folded back and attached to the back surface. A thick skin material 4 is fixed to the surface of the core material 1.

The thickness of this tension member 10 is the same as the thickness of the thin skin material 3.3, and therefore the thickness of the side edge projecting end and the back surface rolling end are also the same.

The material of the tension sheets 1 to 10 is made of vinyl chloride or the like, the same as that of the thin skin material 3.

In addition, the color tone and the like may be either matched to the thick skin material 4 side or to the thin skin material 3 side.

Therefore, C1 when the door trim configured as described above is attached to the door inner panel side, it forms a continuous contour line that corresponds to the contour line of the core material 1, resulting in an extremely good appearance.

Next, FIG. 5 shows a second embodiment of the present invention, in which the tension member 10 is integrally fixed to the end of a thick skin material by sewing 12 instead of high frequency welding 11.

In this embodiment, since the sewing line 12 is ACLEN 1~, in addition to the above-mentioned effects, it is possible to bring about a unique design.
