| description | To provide a seat suspension mechanism having a weight adjustment mechanism that automatically adjusts an upper frame to an equilibrium point, and that can improve vibration absorption characteristics and shock absorption characteristics.SOLUTION: A predetermined twist angle (equilibrium point twist angle) of a lower-frame-side torsion bar 141c determined when an upper frame 200 is positioned at the equilibrium point is obtained in advance, and a twist angle of the lower-frame-side torsion bar 141c in a state that a person is seated is detected. Then, the detected twist angle is compared with the above equilibrium point twist angle, and a control signal is sent to an elastic force adjustment unit, and twist angles of upper-frame-side torsion bars 141a and 141b are adjusted so as to match the twist angle of the equilibrium point. The upper frame 200 can be automatically set to an appropriate position in an initial state in which the person is seated and in a stationary state. Further, since the upper frame can always be guided to the equilibrium point even during running, vibration absorption characteristics and shock absorption characteristics are improved.SELECTED DRAWING: Figure 10
【課題】自動的に平衡点に調整する体重調整機構を備えると共に、振動吸収特性及び衝撃吸収特性を向上させる。【解決手段】平衡点に位置する際の下部フレーム側トーションバー１４１ｃの所定のねじれ角（平衡点ねじれ角）を予め求めておき、人が着座した状態での下部フレーム側トーションバー１４１ｃのねじれ角を検出し、検出したねじれ角を上記の平衡点ねじれ角と比較して、弾性力調整部に制御信号を送り、平衡点ねじれ角に一致するように、上部フレーム側トーションバー１４１ａ，１４１ｂのねじれ角を調整する。人が着座した初期状態、静止状態において、上部フレーム２００を適切な位置に自動的に設定できる。また、走行時にも常に平衡点に誘導できるため、振動吸収特性、衝撃吸収特性を向上させる。【選択図】 図１０ |
