PROBLEM TO BE SOLVED: To provide a bag-like skin-integrated foam molded article of which the number of components is not increased, of which productivity is not lowered without a jig device, and which has a stable quality even if two skin pieces forming a tongue piece part have different resilient forces, and a method for manufacturing the same.SOLUTION: Two skin pieces comprise skin pieces 3 having different resilient forces. A seam line, which forms a bottom surface part 23, is sewn to primary parts 31 of two skin pieces 3 except a bottom surface area of a bag-like skin 2 in which there is a flat cylindrical part 4, and in addition to this, a part E, in which a tongue piece part 33 of the skin piece 3 having a higher resilient force is bent from a bottom surface portion 231, is provided with a fragile part 34 of a stripe shape which weakens an elastic restoration force and enables easy bending.SELECTED DRAWING: Figure 3
【課題】部品点数を増加させず、また治具装置なしで生産性を落とすことがなく、さらに舌片部を形成する二つの表皮片の弾発力が違っていても、品質が安定した袋状表皮一体発泡成形品及びその製造方法を提供する。【解決手段】二つの表皮片は、弾発力が違う表皮片3であり、扁平筒部4が在る袋状表皮2の底面部域を残して、二つの表皮片3の主部31に、底面部23を形成する縫目ラインが縫合されるのに加え、弾発力が高い方の表皮片3の舌片部33が底面部分231から折れ曲がる部位Eに、弾性復元力を弱めて折り曲げを容易にする筋状の脆弱部分34が設けられた。【選択図】図3
