    • The structure is formed by serially connecting a torsion bar and a coil spring via a arm and a supporting frame to thereby elastically support a flat-type supporting member, and by disposing a cushioning member for seat cushion provided with a spring characteristic closely analogous to a load-to-deflection characteristic (spring characteristic) of the muscle of a human body above the flat-type supporting member. Accordingly, it is possible to make a spring characteristic for working when supporting a load of a human different from a spring characteristic for working when removing vibration even with an extremely simple structure. In other words, the structure has an excellent function to make the spring constant at work when removing vibration, especially when removing a high frequency component.
    • 该结构通过臂和支撑框架串联连接扭杆和螺旋弹簧而形成,从而弹性地支撑平板式支撑构件,并且通过设置具有与 在平面型支撑构件上方的人体的肌肉的负载 - 挠度特性(弹簧特性)。 因此,即使采用非常简单的结构,即使在除去振动时,也可以在支承不同于弹簧特性的人的负载时进行加工时的弹簧特性。 换句话说,该结构具有在去除振动时使弹簧恒定工作的优异功能,特别是在去除高频分量时。
