The invention relates to a rotating part of a clutch device of a safety belt retractor, the clutch device and the safety belt retractor, and the rotating part can be jointed with or separated from other rotating parts of the clutch device so as to receive torque from the other rotating parts or freely rotate relative to the other rotating parts. The rotating part can be connected with a reel of the safety belt retractor, the reel is used for winding the safety webbing, and the rotating part can drive the reel to rotate under the condition that torque is received from other rotating parts so as to recover the safety webbing, and the rotating part is characterized by comprising a clutch part which can receive the torque to rotate around a rotating axis; the toothed plate and the clutch piece are coaxially arranged, the toothed plate and the clutch piece are mutually connected to limit relative rotation of the toothed plate and the clutch piece in the circumferential direction, the toothed plate abuts against the clutch piece in the axial direction under the action of elastic bias force, and the toothed plate is further arranged to be capable of being connected with the reel in an anti-torsion mode; and when the torque received by the toothed plate from the reel exceeds a preset value, the toothed plate can resist the elastic bias force to rotate relative to the clutch piece.

    本发明涉及安全带卷收器的离合装置的旋转部件、离合装置以及安全带卷收器,旋转部件能够与离合装置的其他旋转部件接合或分离以从其他旋转部件接收扭矩或相对于其他旋转部件自由旋转,旋转部件还能够与安全带卷收器的用于卷绕安全织带的卷轴接合,并且能够在从其他旋转部件接收扭矩的情况下带动卷轴转动以回收安全织带,其特征在于,旋转部件包括:离合件,其能够接收扭矩而绕旋转轴线转动;以及齿板,其与离合件同轴布置并且与离合件相互接合以限制两者在周向上的相对转动,齿板在弹性偏置力的作用下沿轴向抵靠所述离合件,齿板还设置成能够与卷轴抗扭转接合,并且齿板在从卷轴接收的扭矩超过预定值时能够抵抗弹性偏置力而相对于离合件转动。
