| titleOfInvention | Manufacturing method of different hardness headrest |
| abstract | (57) [Summary] [Purpose] To make it easy to mechanize the manufacturing process of the headrest and reduce the defective rate of the product. [Structure] A mixed solution of isocyanate A and polyol B, which is a raw material of urethane foam, is introduced into a mold 1 composed of an upper mold 11 and a lower mold 12 on which a mold surface corresponding to the surface shape of a headrest is formed. In a method for producing a urethane foam headrest by reacting the isocyanate A and the polyol B in the mixed solution inside the mold 1, in the head contact surface 120 of the mold corresponding to the head contact part of the headrest. A coating layer 2 is formed by applying a polyol in advance, and an isocyanate or a crosslinking agent that accelerates the curing reaction of the isocyanate and the polyol is applied to both sides of the coating layer 2 to form a second coating layer 3, and then the above The mixed liquid is introduced into the mold 1 to react the coating layer 2, the second coating layer 3 and the mixed liquid. |
