What is the seat belt automatic tightening function?

[Ida]

Seat belt automatic tightening function is: when the vehicle is about to or is experiencing a collision, the seat belt will automatically tighten to secure the occupant's body. The function of the seat belt is: when the vehicle collides or emergency braking is applied, the pre-tensioning device will instantly retract, tightening the slack seat belt to firmly secure the occupant in the seat, preventing secondary collisions. The method for replacing the seat belt is: 1. Locate the wiring under the car seat and find the sensor wire for the seat belt buckle; 2. Remove the seat cushion, take out the airbag, locate the bolt securing the seat belt, and remove the seat belt buckle; 3. Find the seat cushion sensor inside the seat cushion and remove it; 4. Install the new seat belt buckle onto the seat and insert the bolt; 5. Install the weight sensor on the car seat, then install the new retractor and tighten it with a wrench; 6. Reinstall the seat cushion onto the car seat and arrange the wiring at the bottom of the seat properly.
