ッション性シート(2)Aの肉薄部分が他方のクッション性
シート(2)Bの肉厚部分に重なる。The cushioning sheet (2) A is a flexible elastic body whose thickness can be changed, and the thin portion and the other thick portion which are formed by stretching when one of them is vacuum formed by the convex die (5). The cushioning sheet (2) B is in a complementary relationship with the thin portion formed by stretching the other side of the cushioning sheet (2) B by vacuum molding with the concave mold (6), and thus the pair of cushioning sheets. When (2) A and (2) B are polymerized, the thin portion of one cushioning sheet (2) A overlaps the thick portion of the other cushioning sheet (2) B.
したがって本発明においては肉厚が均一な内装材を簡単

るいはホットメルト接着剤を介して行なわれる。The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. As shown in FIG. 1, a convex substrate (5) is provided with a porous substrate (1) made of a resin board or the like. A cushion made of a flexible elastic body that can be changed in thickness, such as polyethylene foam, polypropylene foam, polyvinyl chloride foam, or other plastic foam that is formed into a predetermined shape and then set on top of it. When the material (2) A is heated and softened and then placed and vacuum-formed, the cushion material (2) A has a thin portion (a) and a thicker portion (c). At this time, the base material (1) and the cushion material (2) A are adhered to each other by welding or a hot melt adhesive. Then, as shown in FIG. 2, the cushion material (2) B, which is a cushioning sheet, and the skin material (3) are polymerized and heat-softened by a concave mold (6), and then vacuum formed. The cushion material (2) B is made of the same material as the cushion material (2) A, and the skin material (3) is made of non-woven fabric, fiber knitted fabric, polyvinyl chloride leather, or the like. In this case, the cushion material (2) B is thin at the part B and is thick at the other part D. At this time, the cushion material (2) B and the skin material (3) are bonded to each other by welding or a hot melt adhesive.

And the cushioning material (2) B and the skin material (3) are polymerized and adhered to each other to form the interior material (10). At this time, the cushion material (2) A and the cushion material (2) B are bonded to each other by welding or a hot melt adhesive.
Thus, in the interior material (10), the thin portion a and thick portion c of the cushion material (2) A and the thin portion b and thin portion b of the cushion material (2) B have a complementary relationship with each other. 2) The thin part a of A overlaps with the thick part d of the cushion material (2) B, and the thick part c of the cushion material (2) A overlaps with the thin part b of the cushion material (2) B. The cushion material (2) A and the cushion material (2) B form a cushion material (2) having a uniform thickness.
本実施例ではクッション材に基材や表皮材を積層した
が、本発明では基材、表皮材は必ずしも必須のものでは
