The invention provides a lock catch assembly. The lock catch assembly comprises a lock catch used for being matched with a lock tongue to fix a safety belt to a seat; the force limiting module is connected to the lock catch through a connecting component and is used for limiting a force threshold value, and the force limiting module comprises a mandrel which is provided with a hollow structure and is rotatably supported at two shaft ends; the torsion bar is positioned in the hollow inner cavity of the mandrel so as to be coaxially arranged with the mandrel, and only a part of the torsion bar is connected to the mandrel in a manner capable of rotating together; and the limiting piece applies force to the core shaft to prevent the core shaft from rotating, and when the force borne by the lock catch is larger than the force threshold value, the limiting piece elastically deforms to allow the core shaft to rotate, so that the distance between the lock catch and the force limiting module is increased.
本发明提供一种锁扣组件。该锁扣组件包括:锁扣,其用于与锁舌配合以将安全带固定到座椅;和限力模块,其经由连接构件连接到所述锁扣并且用于限定力阈值,其中,所述限力模块包括:芯轴,其具有中空结构并且在两个轴端处被可旋转地支撑;扭杆,其定位在所述芯轴的中空内腔以与所述芯轴同轴地布置,并且,其仅仅一部分以能够一起旋转的方式连接到所述芯轴;和限位件,其向所述芯轴施加力以防止芯轴旋转,并且,在所述锁扣受到的力大于所述力阈值时,发生弹性变形以允许所述芯轴旋转,使得所述锁扣与所述限力模块之间的距离变大。
