The invention provides a safety belt retractor and an automobile seat. The safety belt retractor comprises a cam disc assembly, a transmission assembly and a locking swing assembly. The cam disc assembly is arranged on the first end face of the mechanical plate, and the first end face of the mechanical plate is the end face, facing the locking cover cap, of the mechanical plate. The transmission assembly is connected between the mandrel and the cam disc assembly so as to drive the convex fluted disc assembly to rotate through the transmission assembly under driving of the mandrel, and the convex fluted disc assembly forms an abutting position and a separation position relative to the locking swing assembly in the rotating process. The locking swing assembly is movably arranged at the notch position of the edge of the mechanical plate and swings at the relative abutting position to abut against the cam disc assembly, so that the locking swing assembly is separated from the ratchet wheel assembly to be in an unlocking state, and in the unlocking state, the braid can be rewound and pulled out; the locking swing assembly swings to be separated from the cam disc assembly when located at the relative separation position, so that the locking swing assembly makes contact with the ratchet wheel assembly to be in a locking state, and in the locking state, the braid can be rewound and cannot be pulled out.

    本申请提供安全带卷收器及汽车座椅,安全带卷收器包括凸轮盘组件、传动组件和锁止摆动组件。凸轮盘组件设于机械板的第一端面,机械板的第一端面为机械板朝向锁止罩盖的端面。传动组件连接在芯轴和凸轮盘组件之间,以在芯轴的带动下通过传动组件带动凸齿盘组件转动,凸齿盘组件在转动过程中相对锁止摆动组件形成抵接位置和分离位置。锁止摆动组件活动设置在机械板的边沿的缺口位置,并在相对抵接位置时被摆动以与凸轮盘组件抵接,使锁止摆动组件与棘轮组件分离以处于解锁状态,在解锁状态时,织带可回卷且可拉出;在相对分离位置时摆动以与凸轮盘组件分离,使锁止摆动组件与棘轮组件接触以处于锁止状态,在锁止状态时,织带可回卷且不可拉出。
