An automobile active tightening safety belt comprises an active contraction locking retractor and an active contraction spring bolt. A solenoid valve, a limiting device, a relay switch, a speed measuring sensor, a vehicle speed sensor, a distance sensor, a collision sensor, a tilt sensor, a display screen and a trip computer ECU are included. When a vehicle, a front vehicle and an obstacle are about to collide, during rollover, the trip computer ECU sends a control signal to the relay switch circuit to connect the electromagnetic valve to be powered on; the electromagnetic coil generates an electromagnetic field to shrink the valve rod backwards; and a compression spring elongates, a tension spring shortens, the locking retractor drives the safety belt to be tensioned downwards, circular teeth and vertical teeth rotate downwards to tighten the safety belt twice at the same time, the spring bolt, an inserting buckle and the safety belt are pulled downwards, the safety belt is tightened,the safety belt is tightened actively and can be recovered to be used, the safety belt tightens a driver and passengers on the seat, and secondary injuries caused by loosening of the safety belt to the driver and passengers are avoided.

    本发明汽车主动收紧安全带包括主动收缩锁止卷收器和主动收缩锁舌,电磁阀,限位装置,继电开关,测速传感器,车速传感器,距离传感器,碰撞传感器,倾斜传感器,显示屏和行车电脑ECU当本车与前车,障碍物即将发生碰撞,侧翻时本发明行车电脑ECU将控制信号给继电开关线路接通电磁阀通电,电磁线圈产生电磁场将阀杆向后收缩,压缩弹簧伸长,拉簧缩短,锁止卷收器带动安全带向下拉紧,圆齿向下与竖齿产生转动安全带同时两次收紧,将锁舌,插扣和安全带向下拉动,安全带收紧,主动收紧安全带可恢复使用,安全带将司乘人员收紧在座椅上,司乘人员不会因为安全带松动而造成二次伤害。
