The invention provides a self-adaptive adjusting type spring bolt which is applied to the technical field of vehicle seat safety belt assemblies, when a vehicle is normally used, a pin shaft is kept at a first position of a pin hole through a keeping part of the pin hole, meanwhile, relative rotation of an inserting piece and a spring bolt body is limited through a limiting part, and when the vehicle collides, the pin shaft is kept at the first position of the pin hole. The posture and angle of a passenger change to drive the posture of the safety belt to change, the pin shaft breaks through the retaining part through the pulling force of the safety belt to move out of the first position so that the limiting part can relieve limitation, and the spring bolt body can rotate relative to the inserting piece along with the posture change of the safety belt to conduct self-adaptive adjustment. By means of the structure, the braid and the belt hole in the spring bolt body are in a smooth penetrating state all the time, the braid is not prone to being stacked and clamped, the braid is not prone to being cut off, and better safety guarantee can be provided for passengers.

    本申请提供一种自适应调整式锁舌,应用于车辆座椅安全带组件技术领域,其中,在车辆正常使用时,销轴通过销孔的保持部保持在销孔的第一位置,同时通过限制部限制插片和锁舌本体的相对转动,在车辆发生碰撞时,乘员姿态和角度改变带动安全带姿态发生改变,销轴通过安全带的拉力突破保持部移出第一位置以使限制部解除限制,锁舌本体可以跟随安全带的姿态改变与插片相对转动进行自适应调整,使得织带一直与锁舌本体上的带孔处于平顺穿通状态,不易出现织带堆积卡带,且不易割断织带,能够为乘客提供更好的安全保障。
