The invention discloses a safety belt assembly capable of detecting a fastening state. The safety belt assembly comprises a pressure sensor arranged on a seat, a detection switch in an insertion state, a warning device and a warning controller, and the pressure sensor, the detection switch and the warning device are electrically connected to the warning controller; the safety belt assembly furthercomprises a retractor and a main frame, two ends of the retractor are integrally and rotationally installed on the main frame through rotating shafts, an auxiliary winding spring is further arrangedbetween the retractor and the main frame, and the winding direction of the auxiliary winding spring is opposite to the winding direction of a winding spring; the length of the reversely wound safety belt on the shell is matched with the minimum pull-out length of the safety belt in a correct fastening state; the main frame is provided with a distance sensor arranged towards the shell in the radialdirection, and the distance sensor is electrically connected to the warning controller. The safety belt assembly has the advantages that the combination design is reasonable, the detection means is accurate and reliable, the false insertion state can be identified, and the driving safety is improved.
本发明公开了一种能够检测系扣状态的安全带总成,包括设置在座椅上的压力传感器、插入状态的检测开关、警示装置和警示控制器,压力传感器、检测开关和警示装置均电连接至警示控制器;还包括卷收器和主框架,卷收器的两端通过转轴可整体转动地安装在主框架上,卷收器与主框架之间还设置有副卷收卷簧,副卷收卷簧的卷收方向与卷收卷簧的卷收方向相反;壳体上反向卷绕的安全带长度与安全带正确系扣状态下的最小拉出长度相匹配;主框架上具有沿径向朝向壳体设置的距离传感器,距离传感器电连接至警示控制器。本发明具有结合设计合理,检测手段准确可靠,能够识别假插状态,有利于提高行车安全性等优点。
