The invention discloses a locking device for a safety belt retractor and the safety belt retractor. The locking device is used for locking a driving gear of the safety belt retractor. The locking device comprises a base body, a locking arm, an electromagnetic assembly and an elastic piece. The locking arm is movably arranged on the base body between a locking position and an unlocking position, so that interference with rotation of the driving gear is formed when the locking arm is located at the locking position, and the locking arm is separated from the driving gear when the locking arm is located at the unlocking position. And the electromagnetic assembly is arranged corresponding to the locking arm, and is configured to release the locking arm at the unlocking position when the electromagnetic assembly is not electrified and respond to a trigger signal to form electrification so as to generate magnetic force for driving the locking arm to the locking position. The two ends of the elastic piece are fixedly connected with the base body and the locking arm respectively, and the elastic piece is configured to keep the locking arm in the tendency of the unlocking position. According to the safety belt retractor locking device and the safety belt retractor, the safety belt can be actively locked, the response speed is high, noise is small, and abrasion is small.

    本公开用于安全带卷收器的锁定装置及安全带卷收器,用于对安全带卷收器的驱动齿轮锁定。所述锁定装置包括基体、锁定臂、电磁组件和弹性件。所述锁定臂可在闭锁位置和开锁位置运动地设于所述基体,以在闭锁位置时形成对所述驱动齿轮的转动的干涉,以及在开锁位置时脱离于所述驱动齿轮。电磁组件与所述锁定臂对应设置,被构造成在未通电时释放所述锁定臂于所述开锁位置以及响应于触发信号以形成通电,产生将所述锁定臂驱动至所述闭锁位置的磁力。弹性件两端分别与所述基体和所述锁定臂固定连接,且被构造成将所述锁定臂保持于所述开锁位置的趋势。本公开的安全带卷收器锁定装置及安全带卷收器,能够主动锁定安全带,响应速度快,噪声小,磨损小。
