ダクト入りシートパッドの製造方法及びこれに用いる発泡型
Document Type and Number:
Japanese Patent JP5734496
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method for a seat pad with a duct which prevents a foam material from entering a duct through an air jetting opening.SOLUTION: In a method of manufacturing a seat pad with a duct, an air distribution duct 6 in which an air jetting opening is provided in a duct route is set to a foam mold 7. Then, by injection of foam material m and closing of a mold, a seat pad in which the duct 6 is embedded is foam-molded. By the foam molding, a recess formed on a seat pad surface on a passenger abutment side is made to be an air blowing opening to match with the air jetting opening. At a raised portion 72 for forming a recess, the foam mold 7 in which a cave is dug from its upper surface portion is used to form an annular recess that encloses the air jetting opening, at a duct surface portion of a duct part 66 around the air jetting opening. By setting the duct 6 to the foam mold 7, an upper surface portion of the raised part is made to tightly contact to a duct surface portion so as to close the annular recess. Then, by injection of the foam material m and closing the mold, the duct 6 is inserted to integrally foam-mold with the seat pad.
