According to the safety belt spring bolt structure, a locking assembly comprises a mandrel and a cam sleeve arranged on the mandrel in a sleeving mode, one end of the cam sleeve is in circumferential limiting connection with the mandrel, and the other end of the cam sleeve is in empty sleeve connection with the mandrel; one end of the mandrel is in running fit with the first shaft seat at one end of the belt hole, the other end of the mandrel is in running fit with the second shaft seat at the other end of the belt hole to limit the rotation range, and the mandrel of the mandrel is parallel to the hole length direction of the belt hole. Loosening of the locking assembly is achieved under the limitation of proper damping force, small-distance forward movement of the body of a driver and passengers under the constraint of proper resistance is achieved, and rigid constraint of a safety belt A arranged on the abdomen to the abdomen of the human body is avoided; the violent pressure feeling of the safety belt A on the human body, especially the belly, is effectively reduced, and the health of a driver and passengers is protected.
本发明提供一种安全带锁舌结构,锁紧组件包括芯轴和套设在芯轴的凸轮套管,凸轮套管一端与芯轴构成周向限位连接、另一端与芯轴空套连接,芯轴一端与带孔一端的第一轴座转动配合、芯轴另一端与带孔另一端的第二轴座构成限制转动范围的转动配合,芯轴的轴芯与带孔的孔长方向平行。本发明利用了锁紧组件在适当阻尼力的限制下实现的松动,实现了驾乘人员身体在适当阻力的约束下实现小距离的前移,避免了拦置在腹部的安全带A对人体腹部形成的刚性约束,有效地降低了安全带A对人体尤其是腹部造成的剧烈压刻感,保护了驾乘人员的健康。
