One has a structure in which a metal core material 13 is placed inside a thick urethane foam 12 covered with an outer skin 11 made of ABS resin, and a metal core material 13 is provided for both shape retention and reinforcement. It has been proposed that a metal core material 13 is placed inside a thick integral skin urethane foam 14 in order to simplify the structure, but these conventional products are difficult to soften as parts. Although it has achieved its purpose, there remains room for improvement in terms of cost and weight since the core material occupies a large area in the interior parts.

に大きく貢献しうる製品を提供できるに至つた。 This idea replaces the metal core material and part of the urethane foam used as essential components in conventional products by replacing the hard, relatively thick polyurethane foam with a polyvinyl chloride skin. As a lining layer on the inside of a composite skin formed with a polyvinyl chloride foam layer on the inside, the density when cured is in the range of 0.2 to 1.3 g/cm 3 and the flexural modulus is in the range of 1000 to 20000 Kg/cm 2 By constructing the wall material of the product with a laminate that is integrated so as to wrap around the periphery of the backing layer, the entire surface including the periphery of the product, including the periphery required by the times, has sufficient strength comparable to conventional products. We have also been able to respond to the issue of softness, and have also been able to provide a product that can significantly contribute to reducing product weight and cost.

る。 FIG. 1 shows a console box 1, in which a lid 3 is attached to an opening of a console box main body 2 using a hinge 4 so as to be openable and closable. The console box main body 2, including the lid 3, is made by laminating a polyvinyl chloride foam layer 7 on the inside of a polyvinyl chloride skin 6 to form a composite skin 8. On the inside thereof, there is a backing layer 9 made of relatively thick polyurethane foam that acts as a core material, and a laminate that is integrally laminated so as to wrap the peripheral edge of the backing layer with the composite outer skin 8. It forms the entire wall material of automobile interior parts.

その密度を0.2〜1.3ｇ／cm3に、そして曲げ弾性率
を1000〜20000Kg／cm2の範囲に設定された硬質の
もので、芯材としての適宜の剛性機能と補強効果
を有し、かつ軽量面で顕著な特徴を有している。 The backing layer 9 made of polyurethane foam is hard and has a density of 0.2 to 1.3 g/cm 3 and a flexural modulus of 1000 to 20,000 Kg/cm 2 to provide appropriate rigidity as a core material. It has functions and reinforcing effects, and is also notable for its light weight.
裏打層９の密度を上記数値範囲に設定すること

相対的に求められたもので、又曲げ弾性率を前記
数値範囲に求めた根拠は数値の下限以下とすると

なるという面が派生し芯材としての本来の目的を
逸脱する結果となる。 Setting the density of the backing layer 9 within the above numerical range was relatively determined in relation to the present invention, which aims to reduce the weight of the product, and was also the basis for determining the flexural modulus within the above numerical range. If it is below the lower limit of the numerical value, the flexibility will increase and it will be easily deformed, making it impossible to achieve the purpose as a core material of the product.On the other hand, if it is above the upper limit of the numerical value, the hardness will increase and it will be easy to break. As a result, this aspect deviates from its original purpose as a core material.

ム等がある。 Further, the thickness of the backing layer 9 is determined relative to the above numerical value and the type of automobile interior parts. In addition to the hard urethane foam, the backing layer 9 may be a hard polyurethane foam obtained by RIM molding, or a glass fiber mixed hard polyurethane foam obtained by RIM molding.

First, the skin 6 is formed on the inner surface of the mold by slush molding or rotation molding using a powder material or plastisol of vinyl chloride resin, and then the inner surface of the skin 6 is formed by pouring the vinyl chloride resin containing a foaming agent into the mold. The foam layer 7 is integrally molded to form a composite skin 8. As a final step, the foamed composite skin 8 is set, and then urethane resin is put into a mold and a backing layer 9 made of hard urethane foam or hard urethane foam mixed with glass fiber is placed inside the existing composite skin 8. layered in one layer.

している。 This idea uses a backing layer made of polyurethane foam that has appropriate rigidity and bending elasticity by increasing the wall thickness as an alternative to the conventional metal core material. Even though the foamed layer of the composite shell that covers the surface is significantly thinner than the conventional product, it is not inferior to the conventional product in terms of softness, and the thickness of the backing layer is due to the thickness of the composite shell. We were able to fully compensate for this by making the parts thinner, and without making the product itself particularly large in size, we were able to create a product that does not fall behind in any way compared to conventional products. In addition, in this invention, the integral molding of the outer skin part and the backing layer is made easier and stronger by configuring the outer skin part to wrap around the periphery of the backing layer, and furthermore, the integral molding of the outer skin part and the backing layer is made easier and stronger. A uniform soft feel can be imparted over the entire surface. In addition, the remarkable lightness of the backing layer of this invention compared to conventional metal core materials is realized in the weight reduction of the product.
It also contributes significantly to reducing product costs.
