To provide a generic type belt retractor in which a probability of unwanted engagement of a tensioner connection part is reduced.SOLUTION: A belt retractor includes a belt reel, a belt tensioner, and a tensioner connection part, in which the tensioner connection part is displaceably mounted on a drive wheel and includes, for establishing and cutting off the rotational connection of the drive wheel with the belt reel, at least one coupling pawl and a friction ring that has a control arm coupled with the coupling pawl. When the belt tensioner is activated, the friction ring performs a relative movement to the drive wheel, which is advanced by frictional force, and controls via the control arm the movement of the coupling pawl into engagement and disengagement with a row of teeth. The friction ring and/or the coupling pawl has a block contour, and the block contour is positioned such that the coupling pawl abuts on an upper part after the disengaging movement out of the row of teeth, and is blocked in the direction of a repeated engagement movement into the row of teeth.SELECTED DRAWING: Figure 2

    【課題】テンショナ連結部の望ましくない係合の確率が低減されたジェネリック型のベルトリトラクタを提供する。【解決手段】ベルトリールとベルトテンショナとテンショナ連結部とを備え、テンショナ連結部が駆動ホイール上に変位可能に取り付けられ、駆動ホイールとベルトリールとの回転接続を確立及び切断するために、少なくとも1つの連結爪、及び連結爪に連結された制御アームを有する摩擦リングを備え、ベルトテンショナの起動時に、摩擦リングは、摩擦力によって推し進められる駆動ホイールに対する相対運動を実施し、相対運動によって、制御アームを介して、連結爪が歯列との係合に入り、係合から抜け出す運動を制御し、摩擦リング及び/又は連結爪がブロック輪郭を有し、ブロック輪郭は、歯列からの係合離脱運動後に、上部に連結爪が当接するように位置付けられ、かつ歯列への繰り返しの係合運動の方向にブロックされる、ベルトリトラクタ。【選択図】図2
