Claims (4)
- 衝突時または衝突を予知した際に、車体上方にフードを跳ね上げる際に、跳ね上げによって生じた前記フードの振動である当初振動を減殺する減殺振動を前記フードに加える振動減殺手段を設けたフード跳ね上げ装置において、
前記振動減殺手段は、前記当初振動の位相角が(2nπ−π/3<φ<2nπ+π/3)の範囲にあり、かつ、前記当初振動が上向きの変位となるときに、前記フードの上方移動を規制することによって生じる下向きの規制力を加えることによって、前記当初振動の変位の向きと逆向きの変位である前記減殺振動をフードに加えてフードの振動を減殺し、前記減殺振動の振動変位の所定時間内での時間積分値の絶対値と、前記当初振動の振動変位の所定時間内での時間積分値の絶対値とを、略一致させたことを特徴とするフード跳ね上げ装置。 - 前記規制力を調整する規制力調整機構を備えたことを特徴とする請求項1に記載のフード跳ね上げ装置。
- 前記規制力調整機構は、流体の抵抗を利用して規制力を調整することを特徴とする請求項2に記載のフード跳ね上げ装置。
- 前記規制力調整機構は、材料の変形を利用して規制力を調整することを特徴とする請求項2に記載のフード跳ね上げ装置。
