The invention discloses a safety belt retractor, a safety belt device, a seat and a vehicle, and the safety belt retractor comprises an angle control mechanism which comprises a driving rotating part which is provided with a first rotating axis; the vehicle body sensing mechanism comprises a driven rotating piece, and the driven rotating piece is provided with a second rotating axis; the transmission part is matched with the driving rotating part, the transmission part and the driving rotating part synchronously revolve around the first rotating axis, the transmission part is matched with the driven rotating part, and the transmission part and the driven rotating part synchronously revolve around the second rotating axis; the transmission part transmits the rotating motion of the driving rotating part around the first rotating axis to the driven rotating part so that the driven rotating part can rotate around the second rotating axis. According to the safety belt retractor, constant-speed transmission of the driving rotating part and the driven rotating part can be achieved, and the safety belt retractor has the advantages of being small in energy loss, low in assembly precision requirement, high in transmission stability and the like.

    本发明公开了一种安全带卷收器、安全带装置、座椅和车辆,包括:角度控制机构,包括主动旋转件,所述主动旋转件具有第一旋转轴线;车体感应机构,包括从动旋转件,所述从动旋转件具有第二旋转轴线;传动件,所述传动件与所述主动旋转件配合且与所述主动旋转件同步绕所述第一旋转轴线公转,所述传动件与所述从动旋转件配合且与所述从动旋转件同步绕所述第二旋转轴线公转,所述传动件将所述主动旋转件绕所述第一旋转轴线的旋转运动传递至所述从动旋转件,以使所述从动旋转件绕所述第二旋转轴线旋转。根据本发明实施例的安全带卷收器能够使主动旋转件和从动旋转件等速传动,且具有能量损耗小、装配精度要求低和传动稳定性高等优点。
