PROBLEM TO BE SOLVED: To provide a vehicle seat cushion which secures face rigidity, maintains hardness of a seat, moreover, disperses a load into a plurality of lines of spring members, applies proper sinking, thereby, can improve riding excessive hard feeling, at the same time, suppresses increase of the number of components, weight and personnel expenses and can reduce a load of an operator.SOLUTION: A vehicle seat cushion 20 includes spring members 30, 40 which have a plurality of bend parts 30a, 40a, a bridge member 70 arranged so as to be bridged between the spring members 30, 40, and a connection member 80 which connects the bridge member 70 and the spring members 30, 40. The bridge member 70 is arranged on a position different from the bend parts 30a, 40a of the spring members 30, 40, and is bridged between the spring members 30, 40, and the connection member 80 is formed so as not to include the bend parts 30a, 40a of the spring members 30, 40.

    【課題】面剛性を確保しシートの硬さを維持したうえで、複数本のスプリング部材に荷重を分散させて適度な沈み込みを付与して、硬すぎる乗り心地を改善することができるとともに、部品点数、重量及び人件費の増加を抑制し、作業者の負担を軽減することができる乗物シート用緩衝体を提供する。【解決手段】乗物シート用緩衝体20を、複数の屈曲部30a、40aを有するスプリング部材30、40と、スプリング部材30、40間を架け渡すように配設される架け渡し部材70と、架け渡し部材70とスプリング部材30、40とを連結する連結部材80と、を備える構成とする。架け渡し部材70が、スプリング部材30、40の屈曲部30a、40aとは異なる位置に配置されてスプリング部材30、40間に架け渡されるとともに、連結部材80がスプリング部材30、40の屈曲部30a、40aを内包しないように形成する。【選択図】図1
