Description

[Detailed Description of the Invention] The present invention relates to improvement of interior materials for automobiles.

The surface of a core board made of synthetic resin board, hard fiberboard, etc. is covered with a skin material via a bed material layer, and a part of the surface is covered with a decorative skin material different from the skin material to decorate it. Automotive interior materials with enhanced effects are already known, but the decorative skin materials in conventional automotive interior materials of this type have their peripheral edges attached to the core plate or skin material directly or through a molding material. Since integrated welding is common, the material is limited to heat-adhesive synthetic resins, and there are various drawbacks, such as the need for a lot of work to improve the finish of the welded parts.

The present invention was completed with the aim of creating an interior material for automobiles that does not have the above-mentioned drawbacks.As shown in the illustrated embodiment, slits 2 are provided in a frame shape at required locations on a core plate 1. The inside of the sub-core plate part 1b
The main skin material 3 is coated on the surface of the main core plate portion 1a of the core plate 1, and the outer peripheral edge thereof is fixed to the back surface of the peripheral edge portion of the core plate 1, and the inner surface of the main skin material 3 is coated with the main skin material 3. It is characterized in that the peripheral edge 3' is inserted into the slit 2 so as to overlap the outer peripheral edge 4' of the decorative skin material 4 covered with the sub-core plate part 1b, and fixed to the back surface of the core plate 1. It is something. In addition, 5 and 6 in the figure are a lining material layer such as a polyurethane foam thin layer interposed between the core plate 1, the main skin material 3, and the decorative skin material 4;
In the figure, 7 is the main core plate part 1 on the back side of the core plate 1.
This is a reinforcing plate material that connects the inner circumferential edge part 3' and the outer circumferential edge part 4' together with the sub-core plate part 1b and the inner peripheral edge part 3'.

With this structure, the surface of the core plate 1 is covered with a decorative skin material 4 which is covered with the sub-core plate part 1b inside the frame-shaped slits 2 provided at required locations on the core plate 1. Since it is completely covered with a different type of main skin material 3 having a different material or color from the decorative skin material 4 covered on the main core plate portion 1a, only one type of skin material can be used. It is similar to conventional automotive interior materials of this type in that it has a superior decorative effect compared to automotive interior materials that are completely coated, but the outer periphery is covered with a core plate 1. All or most of the inner circumferential edge 3' of the main skin material 3 which is fixed to the back surface of the peripheral edge part and covered with the main core plate part 1a, and the decorative skin material which is covered with the auxiliary core plate part 1b. All or most of the outer peripheral edge 4' of the core plate 1 is inserted into the frame-shaped slit 2 provided in series or partially in the core plate 1, and is inserted into the back surface of the core plate 1, that is, the sub-core plate part 1b. Since the slits 2 are fixed to the back surface of the periphery of the slit 2 or the back surface of the periphery of the main core plate portion 1a using adhesive, staples, or any other fixing means, a valley-like pattern is formed in the slit 2, which prevents post-processing. Even without this, a beautiful finish can be obtained on the surface side, and since the sub-core plate portion 1b utilizes one core plate 1 together with the main core plate portion 1a, there is no wastage of material. It also has the advantage of being lightweight. Moreover, since there is no need to weld the main skin material 3 and the decorative skin material 4, the material for both is not limited to heat-adhesive synthetic resin, and can be combined with any material such as woven fabric, leather, etc. It can be enriched. Therefore, in order to manufacture such an automobile interior material, slits 2 are provided in a frame shape at required locations on the core plate 1, and the slits 2 are placed on the main core plate portion 1a of the core plate 1 with a cloth layer interposed therebetween. The main skin material 3 is coated, the outer peripheral edge thereof is wrapped around the back surface of the core plate 1, and fixed with staples, etc., and then the decorative skin material 4 is also covered on the sub-core plate part 1b via the bed material layer. The outer peripheral edge 4' of the main skin material 3 is overlapped with the inner peripheral edge 3' of the main skin material 3, and the inserted part is inserted into the slit 2.
Since it is only necessary to pull it in along the direction b and fix it with staples or the like, it has the advantage that it can be easily mass-produced and can be provided at a low cost. Note that when other members 9 such as armrests are attached to the surface as in the second embodiment shown in FIG. When the slit 2 is partially provided as in the third embodiment shown, a groove 10 is formed between the slits 2 and 2.
A retainer 11 with claws 11' is attached to this groove 10, and a part of the inner peripheral edge 3' and a part of the outer peripheral edge 4' that remain on the surface side without being inserted into the slit 2 are removed. It goes without saying that the retainer 11 may be embedded in the groove 10 and locked therein.

Therefore, the present invention has great practical value as it eliminates the drawbacks of conventional interior panels for automobiles of this type.
