  According to the survey data in Taiwan, the ratio of death and injury of drivers and front seat passengers wearing safety belts and not wearing safety belts during a traffic accident is 1: 7. This figure proves the importance of wearing safety belts sufficiently. doing. As a result, the government has enacted a law that requires the use of a safety belt when driving. The exact method of wearing the safety belt is as follows. Most new safety belts are automatic, but there are a few things to keep in mind (especially for manually adjustable safety belts): That is, fix the user's buttocks so that the lateral belt of the safety belt crosses over the thigh instead of the user's abdomen, and further hangs the slant belt in the middle of the shoulder so that it tightly contacts the clavicle position of the chest, and The buckle is hung on the side of the body to prevent other objects from being entangled or pressed against the safety belt and to prevent twisting, and then locked. If necessary, adjust the tension of the safety belt. However, it is uncomfortable when the user is sitting too tight. As a result, a positioning device for adjusting the length of the safety belt has appeared on the market.

  As shown in FIGS. 1 and 2, a generally used positioning device a is composed of an upper cover a1 and a lower cover a2, and a plurality of ridges a11 and a21 are formed on the inner surfaces of the upper cover a1 and lower cover a2. In addition, one side of the upper cover a1 and the lower cover a2 is connected to each other by a connecting part a3, and a locking part a12 and a locking hole a22 are provided at the other end. At the time of use, the length is adjusted to the required length according to the body shape of the passenger first, and when the upper cover a1 and the lower cover a2 are subsequently closed, the positioning device a holds the safety belt b by the ridges a11 and a21. The safety belt b is not pulled back by the pulling force of the internal spring, and an appropriate degree of tension is generated to increase the comfort. However, when an emergency situation occurs, the spring inside the safety belt b generates an inward pulling force and is blocked by the positioning device a, so that the safety belt b cannot be automatically adjusted according to the situation. The protective function of b is greatly reduced.

  In view of the drawbacks of the above-described safety belt positioning device, the present invention is a positioning device that is particularly easy to install and convenient for adjustment, and when an emergency situation is encountered, the locking member is caused by the tensile force generated by the safety belt. It is intended to provide a positioning device capable of automatically releasing elastically to prevent the safety belt from being lowered in its protective function.
