The invention relates to the technical field of safety belts, in particular to a safety belt retractor and a safety belt assembly.The safety belt retractor comprises a shell, a winding roller, a winding assembly, a safety belt and a fixing assembly, the fixing assembly comprises a clamping shell, a rotating shaft, a fixing plate and conical teeth, and a human body on a seat is limited and protected by pulling the safety belt; after the safety belt is continuously pulled to move out by a certain distance, the clamping shell slides, the left end of the clamping shell makes contact with the right end of the shell, then the fixing plate is pushed to move, the conical teeth are made to be close to the safety belt, and finally the conical teeth are inserted into the safety belt, so that the clamping shell is fixed to the outer side of the safety belt, and the safety belt is loosened; at the moment, due to the fact that the tightening spring deforms to drive the winding roller to wind the safety belt, the clamping shell abuts against the outer shell, the mode that the safety belt is limited through a contracting fastener is replaced, the safety belt can be moved out without continuously pressing a locking fastener, force applied to the hand is reduced, and discomfort such as aching pain of the hand is avoided.
本发明涉及安全带技术领域,具体涉及一种安全带卷收器以及安全带总成,包括外壳、收卷辊、收卷组件、安全带和固定组件,固定组件包括卡壳、转轴、固定板和锥齿,通过牵拉安全带对座位上的人体进行限位保护,通过继续牵拉安全带移出一定的距离后,滑动卡壳,使得卡壳的左端与外壳的右端接触,接着推动固定板移动,使得锥齿靠近安全带,最后使得锥齿插入至安全带中,实现将卡壳固定在安全带的外侧,松开安全带,这时由于收紧弹簧形变驱使收卷辊对安全带进行收卷,使得卡壳与外壳抵接,代替使用缩扣件对安全带进行限位,不需要持续按压锁扣件就能将安全带移出,减少手部的用力,避免手部产生酸痛等不适感。
