PURPOSE:To integrally mold cushioning body without impairing air permeability by a method wherein the cushioning body is integrally foam-molded onto the surface on the side of a high density layer formed on the side opposite to a side, onto which an open cell sheet joined on the back of a skin material is joined. CONSTITUTION:A high density layer 4 is formed by plastically deforming the one face of an open cell sheet 3, the other face of which is joined onto the back side of a skin material 1. In order to manufacture a cushioning body 2 integral with the skin material 1 by means of foaming resin, foaming resin is poured onto the inner surface side of the high density layer 4 so as to foam under low pressure. The external appearance of the skin material 1 of the integrally foam- molded product obtained in the above-mentioned method is free from being marred, because the foaming resin does not soak through the high density layer 4 outwards. In addition, because some foaming resin permeate into and harden the surface layer side of the high density layer 4, the cushioning body 2 and the open cell sheet 3 are made into an integral body and, together with the air permeability held by the open cell sheet 3, a soft product with favorable cushioning property and excellent surface feeling is realized. |
