The invention discloses an automobile tightening safety belt, which is characterized in that a braid is connected with a middle shaft and a buckle in a contraction retractor, an insertion and suspension clasp penetrates through the braid and is inserted into a contraction spring bolt, an electromagnetic valve wire is connected with a relay switch, and the relay switch is connected with a central processing unit. While an automobile is driving, when the distance between the automobile and a front vehicle or an obstacle is smaller than a safe distance, a spring bolt in the contraction spring bolt and the inserted downward sliding braid are controlled to be tensioned, a retractor in a contraction retractor downwards slides to be tensioned, vertical teeth and a gear rotate to drive a middle shaft to rotate, the braid is tightened for the second time, and secondary injury caused by loosening of the safety belt when the driver and the conductor are collided is prevented and avoided.

    本发明公开一种汽车收紧安全带,织带与收缩卷收器内中间轴和扣连接,插和吊扣穿在织带上,插插在收缩锁舌内,电磁阀电线与继电开关连接,继电开关与中央处理单元连接,汽车在行驶过程中,本发明能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,竖齿与齿轮产生转动带动中间轴转动,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。
