AI Technical Summary

Problems solved by technology

[0002] See eg Figure 1 and Figure 2 , a three-point seat belt is usually installed on the existing bus driver's seat, and the seat belt buckle 500, the safety retractor 600 and the seat belt guide ring 700 are all fixed on the seat, and are located on the seat back for safety protection. The height of the seat belt guide ring 700 with guide cannot be adjusted, so that the position of the seat belt exit point from the front of the seat back cannot be adjusted

When drivers of different heights and builds wear seat belts, since the height of the seat belt guide ring 700 cannot be adjusted, people's shoulders may be tightened to varying degrees by the seat belts, which cannot reduce the safety of the seat belts.
