The invention discloses a retractor device, a safety belt device, a seat and a vehicle. The retractor device comprises a force limiting assembly, a pre-tightening mechanism and a clutch supporting plate, and the pre-tightening mechanism is arranged at the end of the force limiting assembly; when the retractor device carries out pre-tightening work, a pre-tightening mechanism can generate remarkable axial or radial pressure in the working process, and if the pressure cannot be effectively managed, adverse effects on the overall performance and the service life of the retractor can be possibly generated, however, according to the invention, a clutch supporting plate is additionally arranged; the clutch supporting plate is arranged between the force limiting assembly and the pre-tightening mechanism, so that the clutch supporting plate can bear at least part of radial pressure generated when the force limiting assembly deviates from the axis and rotates at the same time, the stability of the structure can be effectively enhanced, the service life is prolonged, the driving experience is improved, and the positive effects of reducing noise and vibration and the like are achieved.

    本发明公开了一种卷收器装置、安全带装置、座椅及车辆,包括限力组件、预紧机构、离合托板,预紧机构设于限力组件的端部;在卷收器装置进行预紧工作时,预紧机构工作过程中会产生显著的轴向或径向压力,这些压力如果得不到有效管理,可能会对卷收器的整体性能和寿命产生不利影响,而本发明通过增加一个离合托板,将离合托板设于限力组件与预紧机构之间,使其能够承受限力组件偏离轴心同时旋转的至少部分径向压力,可以有效的增强结构的稳定性、延长使用寿命、提升驾驶体验以及降低噪音和振动等方面都具有积极的效果。
