What are the principles of seat belt usage?

The principles of seat belt usage are as follows: Regularly check the condition of the seat belt. When pulling the belt downward slowly by hand, it should smoothly extend from the retractor. If the belt can be pulled out with a sudden jerk, it indicates failure and requires immediate replacement if damaged. All bolts securing the seat belt to the floor near the seat should be tightened according to specifications, with sealant applied around them. Before using the seat belt, pull out the lap belt as much as possible, adjust the buckle near the waist, and loop the remaining belt over the shoulder. Adjust the shoulder strap length to fit snugly across the chest, leaving enough room to fit a fist. The three-point lap belt should be worn as low as possible over the hips, not the waist. The shoulder belt should not be placed under the arm but should cross the chest diagonally. Precautions for seat belt usage: Seat belts are for individual use only; sharing is strictly prohibited. Avoid twisting the belt while wearing it. Do not let the belt press against hard or fragile objects, such as glasses, pens, or keys in clothing. Keep the belt away from sharp objects to prevent damage. When the seat is unoccupied, retract the belt into the retractor. To remove the belt, hold it with your left hand, press the buckle release with your right hand, and gently guide it back with your left hand. Do not let go immediately to prevent the metal buckle from snapping back and causing injury or damage. Avoid reclining the seat back too far, as this may hinder the belt's extension and retraction, reducing effectiveness. Always fasten the buckle securely to prevent accidental release under force. After any accident, the seat belt must be reset. During a severe collision, the belt stretches, and many components, including sensors, are designed for one-time use.
