BODY SUPPORT DEVICE FOR CHAIR OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To improve the durability of a sheet in a seat body comprising a frame covered with the net-like sheet. SOLUTION: The circumferential part 4a of the sheet encloses a frame 3 from the outside, and an edge 4b of a sheet 4 is fixed to the lower surface of the frame 3. A cushioning material 11 such as rubber is arranged on the outer surface of a corner part 3a of the frame 3. The load to the sheet 4 can be reduced by the presence of the cushioning material 1 to prevent the sheet 4 from being broken by the corner 3a. Since a projection 13 of the cushioning material 11 is fitted to a groove 12 of the frame 3, the cushioning material 11 is retained without being dropped out.
