Description

本発明は自動車用シートに備える孔開きヘッドレストの製造方法に関する。       The present invention relates to a method for manufacturing a perforated headrest provided in an automobile seat.

中央部に前後方向に貫通する貫通孔を有する従来のヘッドレストは通孔を有するため、多数の表皮片を接ぎ合わせて筒状の前側表皮材を縫製し、この前側表皮材内にシートバック側に支持されるステーと一体で芯材を架設したＵ形状のフレームを前記通孔を形成する部分のスリットより挿入した後、スリットをホックで閉口し、然る後、これをパッド成形用の成形型に配設して、前側表皮材内にパッド成形用の発泡液を注入して、前側表皮材と一体にパッドを発泡成形している（例えば特開２００１-３１４２７１号公報）。       Since a conventional headrest having a through-hole penetrating in the front-rear direction at the center has a through-hole, a large number of skin pieces are joined together and a cylindrical front skin material is sewn, and the front skin material is placed on the seat back side. After inserting a U-shaped frame with a core material integrated with the supported stay through the slit of the part forming the through hole, the slit is closed with a hook, and then this is a molding die for pad molding The foaming liquid for pad formation is injected into the front skin material, and the pad is foam-molded integrally with the front skin material (for example, JP-A-2001-314271).

特開２００１-３１４２７１号公報JP 2001-314271 A

従って、前記製造方法によるヘッドレストは、前側表皮材内に対するフレームの挿入が容易になるが、多数の表皮片を縫製により接ぎ合わせで形成するため、接ぎ合わせた部分がハギラインになり、ヘッドレストの外観品質が損なわれる。       Therefore, in the headrest according to the manufacturing method, it is easy to insert the frame into the front skin material, but since many skin pieces are formed by sewing together, the joined portions become hook lines, and the appearance quality of the headrest Is damaged.

また、貫通孔が例えば上下二個を有するものの如く、複雑な形状のものは製造できない。       Also, a complicated shape such as one having two through holes in the upper and lower sides cannot be manufactured.
