Description

[Detailed Description of the Invention] The present invention relates to an automobile lining material used for lining an automobile interior panel such as an automobile door interior panel.

Recently, some in the industry have attempted to use thick carpet fabrics, such as uncut pile or cut pile, which have loops and furrows with pile lengths of several millimeters or more on the surface, as lining materials for automobiles. However, since this kind of carpet material is quite thick, the treatment of the side edges is troublesome, and the use of good-looking carpet material for automobile interior panels has not become widespread, and it is difficult to achieve a luxurious appearance. There is a strong demand in the industry for the development of an automotive lining material that can be used on carpeted surfaces and is easy to line with.

The present invention was completed with the aim of producing an automobile lining material that met the above-mentioned demands, and will be described in detail below using the illustrated automobile door as an example.

1 is a base material 2 knitted with thin strings made of synthetic resin such as polyester fiber, and a tufting machine is used to form countless ring-like or fuzzy loops made of thermoplastic synthetic fibers such as polyamide fiber. In the carpet area where pile 3 is planted, the carpet area 1
A thermoplastic synthetic resin base 4 such as polyethylene resin or polypropylene resin is integrally adhered to the back surface of the base material 2 to form a main lining material 5 having a desired shape. Reference numeral 6 denotes a required side edge portion of the main lining material 5. In this embodiment, the peripheral portion is compressed by a required width using a high frequency welding device or a heating plate, and the pile 3 on the surface is collapsed by the hot pressure. An appropriate number of attachment holes 7 are punched out at required locations on the thin edge 6. Reference numeral 8 denotes a belt-shaped leather fabric made of a thermoplastic synthetic resin material for edging, which is sewn in the middle to the base 6' of the thin edge part 6 extending from the lower side to both sides. 9, the hard plate 9 is folded back from the upper surface of the thin edge 6 to cover the lower edge and both side edges of the hard plate 9, and in this state, the hard plate 9 is attached to the lower half of the door panel. The hard plate 9 is fixed with a stopper 11 that is inserted into a mounting hole 10, and the thin edge part 6 of the upper edge is attached to the upper half of the door panel. The mounting hole 7 is inserted through and locked into a stopper C which is interposed between the door panel A and the door panel A and which fixes the automobile interior panel B.

In this structure, a thermoplastic synthetic resin material 4 is integrally attached to the back surface of a carpet material 1 whose main lining material 5 is a countless number of piles 3 such as cut pile or uncut pile formed on the surface. Therefore, it goes without saying that the pile 3 on the surface has a luxurious appearance, and the required side edge portions of the main lining material 5 are made of thermoplastic synthetic fibers on the surface of the carpet material 1. The thin edge part 6 is formed by compressing countless piles 3 between pressing molds of a high-frequency welding device, a heat welding device, etc., and is made to lie down by hot pressure. When the thin edge portion 6 is placed on the edge of the hard plate 9 and used as an interior panel for an automobile, the thin edge portion 6 is placed on the edge of the hard plate 9, and a strip of leather as shown in the figure is applied from the surface of the thin edge portion 6 to the back surface of the edge of the hard plate 9. It is very easy to fix by rolling up the base 8, or by pulling the thin edge part 6 outward from the side edge of the hard plate 9 and sandwiching it between another automobile interior plate which is separately fixed to the door pile. The automobile door thus obtained can be made into an automobile door by a suitable means, and the automobile door obtained in this way has a thin edge portion 6 on the required side edge portion of the main lining material 5. The thermoplastic synthetic resin material 4 does not cause the edges to swell up and become unsightly, unlike when thick carpet material is used as is, and is integrally attached to the back surface of the main lining material 5. Moreover, the thin edge part 6 formed by laying down the pile 3 by heat pressure prevents the pile 3 made of thermoplastic synthetic fibers from returning to its old state due to the influence of heat. Moreover, a part of the thermoplastic synthetic resin material 4 is also made into a main lining material 5 by heat pressure.
It digs into the edges and almost completely prevents fraying from the periphery, resulting in a beautiful appearance for a long time.

Therefore, the present invention has great practical value as an automobile lining material because the side edge portions can be easily treated, the lining work is easy, and it has an extremely luxurious appearance.
