    摘要: In manufacturing molded product of urethane foam, a releasing agent mainly composed of organopolysiloxane is applied on the inner surface of the mold maintained at 60.degree. C. The agent is prepared by dissolving the base composed of organopolysiloxane composition in an organic solvent. The organopolysiloxane composition comprises (a) a first organopolysiloxane of which 0.1 to 5.0% of all organic groups bonded with Si atoms are vinyl groups and at least 80% of the remaining organic groups are methyl groups, and (b) a second organopolysiloxane containing at least three Si bonded hydrogen atoms in one molecule, wherein the first and second organopolysiloxanes contain Si vinyl groups and SiH groups at a ratio in a range of 1:0.5 to 1:5, and do not substantially contain unreactive siloxane. The agent is cured by irradiation with ultraviolet rays, and a thin and uniform film of releasing agent is formed on the inner surface of the mold. Inside the mold coated with this film of releasing agent is injected a raw liquid of urethane foam of cold cure-type, and after the curing step, a molded product of urethane foam in a desired shape is manufactured.

    摘要: A breathable seat comprises a seat body formed of urethane foam, a three-dimensional network cushion body incorporated in that region of the seat body which bears a user's body, a seat cover having breathability, and a pan frame. The cushion body is formed of a large number of continuous linear elements of thermoplastic resin. The linear elements are looped windingly so that their respective contact portions are fused together. The seat body is formed having venting holes that penetrate the urethane foam in its thickness direction. The venting holes communicate with the cushion body and apertures of the pan frame. The seat cover envelops the seat body and the cushion body.

    摘要: A cushion manufacturing apparatus comprises a plurality of nozzles for continuously discharging a softened thermoplastic resin, thereby looping a plurality of continuous filaments with the respective contact portions thereof bonded together, first guide portions (41, 42) for moving the continuous filaments inward from opposite surfaces in the thickness direction of the cushion member as the filaments are looped, and second guide portions (43, 44) for moving the filaments inward from the opposite sides of the cushion member. The guide portions (41, 42; 43, 44) are provided with a plurality of rollers (50, 52, 60, 62) individually having outer peripheral surfaces projected or recessed corresponding to the outline of the profile of the cushion member and belts (54, 55, 64, 65) stretched between the rollers and capable of endlessly running to change the respective shapes thereof depending on the respective shapes of the outer peripheral surfaces of the rollers, thereby forming the shaping guide surfaces (56, 57, 66, 67).
