Abstract
In a method of manufacturing a seat by using adhesives in which an air permeable skin material and a cushioning pad are bonded to each other by means of reactive hot-melt adhesives, the method comprises a step of coating adhesives to the cushioning pad, a step of provisionally assembling the skin material to the cushioning pad from the side of the adhesive coating surface, a step of setting the provisionally assembled cushioning pad and skin material to an attaching die, a step of applying heating by a heating die to the skin material and the cushioning pad attached in the attaching die assembling step from the side of the skin material and a step of applying cooling under pressure by a cooling die from the surface of the skin material subsequent to the heating step. A seat comprising a skin material and a cushioning pad can be molded with a seat frame by this method. It enables easy positioning, bonding of the skin material even to a deep recess of the cushioning pad, shortening the molding cycle, and keeping the raised skin material intact.
