According to the automobile safety belt capable of being tightened actively, one end of a woven belt is connected with a retractor center shaft in a contraction retractor, the other end of the woven belt is connected with a belt buckle and inserted into a contraction spring bolt, a first electromagnetic valve and a second electromagnetic valve are connected with an electromagnetic valve relay switch, the electromagnetic valve relay switch is connected with a central processing unit starting module, and a third electromagnetic valve and a fourth electromagnetic valve are connected with a switch. When the distance between an automobile and a front vehicle or an obstacle is smaller than a safe distance, the lock tongue in the contraction lock tongue and the woven belt inserted downwards are controlled to be tensioned, the retractor in the contraction retractor slides downwards to be tensioned, the woven belt is rotated by a gear on a center shaft of the retractor, and meanwhile secondary tightening is conducted; and secondary injury caused by loosening of the safety belt when the driver and the conductor are collided is prevented and avoided.

    本发明主动收紧汽车安全带是,织带一头与收缩卷收器内卷收器中心轴连接,一头与带扣连接,插插在收缩锁舌内,第一和第二电磁阀与电磁阀继电开关连接,电磁阀继电开关与中央处理单元启动模块连接,第三,第四电磁阀与开关连接,本发明在汽车与前方车辆或障碍物之间的距离小于安全距离时,控制收缩锁舌内锁舌和插向下滑动织带拉紧,收缩卷收器内卷收器向下滑动织带拉紧,卷收器中心轴上齿轮转动织带同时二次收紧,预防和避免了司乘人员在发生碰撞时由于安全带松动造成二次伤害。
