MSB-active integrated motor pre-tightening seat belt is a seat belt operating mechanism that acts on the seat belt to improve driving comfort. It uses a high-speed DC motor to actively tighten the seat belt during emergency braking or rapid turning, and restrain the driver on the seat back to prevent serious injury to the driver and passengers.
