What are the contents of the visual inspection before using the seat belt?

[LaSawyer]

The contents of the visual inspection before using the seat belt include checking whether the webbing has deteriorated, whether the buckle has cracks, and whether the spring mechanism of the buckle functions properly. Correct usage method of the seat belt: Gently pull the tongue and pass the seat belt across the chest and hips, checking for any knots or twists. Insert the tongue into the buckle until you hear the sound of engagement. The lumbar seat belt must fit snugly against the pelvis and be fastened as low as possible. Adjust the hip section of the seat belt to ensure it is tightly connected to the hips. To release, press the button on the seat buckle to open the tongue and loosen the seat belt. The retractor mechanism is located on the tongue side, allowing the seat belt to automatically tighten. Importance of the seat belt: It protects the driver and passengers by restraining them in their seats during emergency braking, preventing them from being thrown forward and thus avoiding secondary impact injuries. In the event of a collision or when emergency braking is applied, the pre-tensioner device instantly retracts, tightening any slack in the seat belt and securing the occupants firmly in their seats to prevent secondary collisions. If the retraction force exceeds a certain limit, the force limiter device will appropriately loosen the seat belt to maintain stable chest pressure. Therefore, the car seat belt serves to restrict movement and absorb impact energy, mitigating inertial forces and reducing or preventing injuries to the occupants.
