To properly support a load of a person seated on a seat by a flexible elastic surface material.SOLUTION: A support body 20 for supporting in a planar state, a load of a person seated on a seat from a lower side comprises: a panel frame 21 having an outer peripheral frame part 21A along a peripheral edge and a panel part 21B covering inside of a frame of a front region of the outer peripheral frame part 21A for receiving a load of a person seated on a seat from a lower side in a planar state; and a net material 22 which is extended between a rear edge of the panel part 21B and a front edge of a rear frame 21Aa of the outer peripheral frame part 21A, for elastically supporting a load of a person seated on a seat from a lower side in a planar state. A connection position Pr of the net material 22 with the rear frame 21Aa is set on a rear side of a reference position Ph to which an ischial tuberosity point HPa of a person contacts, by a prescribed interval Lr, and the connection position Pf of the net material with the rear edge of the panel part 21B is set to a rear side of a position where is a front side of the reference position Ph by the prescribed interval Lr.SELECTED DRAWING: Figure 3

    【課題】着座者の荷重を可撓性の弾性面材により適切に支持できるようにすること。【解決手段】着座者の荷重を下側から面状に支持する支持体20は、その周縁に沿った外周枠部21Aと外周枠部21Aの前部領域の枠内を覆って着座者の荷重を下側から面状に受け止めるパネル部21Bとを備えたパネルフレーム21と、パネル部21Bの後縁と外周枠部21Aの後枠21Aaの前縁との間に架橋されて着座者の荷重を下側から面状に弾性支持するネット材22と、を有する。ネット材22の後枠21Aaとの接続位置Prが、着座者の坐骨結節点HPaの当てられる基準位置Phより後側に所定間隔Lrあけた位置に設定され、ネット材22のパネル部21Bの後縁に対する接続位置Pfが、上記基準位置Phから前側に上記所定間隔Lrあけた位置より後側の位置に設定されている。【選択図】図3
