Claims (3)
- 歩行者との衝突の際に自動車のボンネット(11)を上昇させるための安全装置(1)であって:
前記ボンネット(11)を上昇させるために前記ボンネットに連結された上昇機構(3;4)と;
前記上昇機構(3;4)に連結され、前記上昇機構(3;4)を展開させることができる火薬式アクチュエータ(2)と;
前記火薬式アクチュエータ(2)が始動されない限り前記上昇機構(3;4)を予め定められた初期位置で動かないようにすることが意図されたロック装置(5)にして、前記火薬式アクチュエータ(2)が作動されたとき前記上昇機構(3;4)を解放するロック装置(5)と、を具備する安全装置(1)において、
前記火薬式アクチュエータ(2)は:
推力ピストン(17)と;
前記推力ピストン(17)を収容する中空本体(16)にして、小径上流部分(18)と、大径下流部分(19)と、前記小径上流部分(18)と前記大径下流部分(19)とを接続する発散通路部分(20)とを有する中空本体(16)と;
前記推力ピストン(17)の周縁に環状に形成された周縁溝(23)に収容されたプレストレス部材(24)と;を具備しており、
前記火薬式アクチュエータ(2)の始動によって、前記推力ピストン(17)は、前記周縁溝(23)に収容された前記プレストレス部材(24)が前記小径上流部分(18)から前記大径下流部分(19)へ向けて移動して弛緩するまで一方向へ滑動させられて、弛緩した前記プレストレス部材(24)が、前記ピストン(17)の前記一方向とは反対の他方向への移動を外部からの力が作用しない限り阻止するように、及び
上昇された前記ボンネット(11)への歩行者の衝突に続いて、弛緩した前記プレストレス部材(24)が、前記ピストン(17)と共に前記他方向へ移動し、該移動の間に前記中空本体(16)を変形させることにより前記ピストン(17)の移動にブレーキがかけられるように構成され、その結果歩行者に対する衝撃が緩和されることを特徴とする、安全装置(1)。 - 前記プレストレス部材(24)がスナップリングから構成されることを特徴とする、請求項1に記載の安全装置。
- スナップリング(24)が円形断面を有することを特徴とする、請求項2に記載の安全装置。
