Claims (10)
- リトラクタ内に回転するように取り付けられたスプール(1)と、前記スプールの一方の端部に取り付けられたロックリング(3)と、衝突時に前記ロックリングを回転しないようにロックするロック爪(22)と、前記ロックリング(3)がロックされた後で、乗物の乗員の前方への運動量の働きを受けてシートベルトウェビングをさらに繰り出すのを可能にする荷重制限手段とを有し、前記荷重制限手段は、ある長さのワイヤ(4)と、前記スプールおよび前記ロックリングの一方に取り付けられた巻き取りドラム(5)と、前記スプールおよび前記ロックリングの他方に固定されたピン(6)とを有し、前記ワイヤは、前記ピンの周りに巻かれ、かつ前記ワイヤは、前記スプール(1)と前記ロックリング(3)が相対的に移動したときに、前記ワイヤ(4)が前記ピン(6)の周りを回って引っ張られて、前記巻き取りドラム(5)上に巻かれるように構成されており、前記巻き取りドラム(5)は、前記ワイヤ(4)のコイルの半径が徐々に変化するようになったらせん状部材として形成されているシートベルトリトラクタ。
- 前記ワイヤ(4)は、前記ピン(6)の周りに複数回巻かれている、請求項1に記載のリトラクタ。
- 前記ワイヤ(4)の、前記らせん状部材上の接触点は、所望の荷重制限作用を決定するように選択される、請求項1に記載のシートベルトリトラクタ。
- 前記らせん状部材は、回転する前記ワイヤがより大きな半径の部分に飛び移り、したがって、トルクを段階的に低減させ、2段階の荷重制限作用を生じるように形成されている、請求項3または1に記載のシートベルトリトラクタ。
- 前記らせん状部材が前記スプール(1)の本体に組み込まれている、請求項1から4のいずれかに記載のシートベルトリトラクタ。
- 前記らせん状部材が前記ロックリング(3)に組み込まれている、請求項1から4のいずれかに記載のシートベルトリトラクタ。
- 前記ワイヤ(4)は前記スプールに固定され、前記ピン(6)は前記ロックリング(3)に取り付けられている、請求項1から4のいずれかに記載のシートベルトリトラクタ。
- 前記ワイヤ(4)は、第1の真っ直ぐな部分またはわずかに曲がった部分と、これに続く1つまたは2つ以上のコイルと、これに続く第2の真っ直ぐな部分とを有して、スチールで予め形成され、前記ピン(6)は前記コイルに挿入されている、請求項1から4のいずれかに記載のシートベルトリトラクタ。
- 前記ワイヤは少なくとも1本のピン(6)を半径方向に包囲するように配置されている、請求項1から4のいずれかに記載のシートベルトリトラクタ。
- 前記ワイヤ(4)は、前記ピン(6)を軸方向に包囲するように配置されている、請求項1から4のいずれかに記載のシートベルトリトラクタ。
