METHOD FOR MANUFACTURING BODY SUPPORTER FOR SEAT BODY OF CHAIR AND BODY SUPPORTER

摘要

PROBLEM TO BE SOLVED: To prevent an end face protruding in a needle shape from the cut end face of a cushion material with a solid network structure formed by bonding together many entangled loop shaped linear materials made of resin used for a body supporting member such as a seat body of a chair or the like at respective contact positions from breaking a cover material. SOLUTION: A cushion material 3 is cut into a substantially trapezoidal shape in section so that one wide face 3a of front and back wide surfaces is wider than the other wide face 3b. The edge parts 4a of a skin material 4 bonded to the wide face 3a by an adhesive agent are projected from the cushion material 3. The wide face 3b is bonded to the surface of an inner shell 2 by an adhesive agent 5. The peripheral cut face of the cushion material 3 is covered with the peripheral edge part of the wide face 3a o be deformed so as to come near to the peripheral edge of the inner shell 2. The edge 4a of the cover material 4 is fixed to the back surface side of the inner shell 2 by an rest adhesive agent 6.
