What is the service life of a car seat belt?

[DeXavier]

Seat belts generally have a service life of 3 to 5 years. The specific duration depends on the level of care during regular use. Seat belts should be inspected periodically to extend their lifespan. However, if a seat belt cannot be tightened properly, it should be replaced immediately to prevent safety hazards. During a collision while driving, passengers may lurch forward, subjecting the seat belt to significant impact, which necessitates prompt replacement. Seat belts are devices installed in vehicles to reduce passenger and driver injuries when the car body experiences severe impact. Public security authorities mandate that all front-seat occupants must wear seat belts, as they provide restraint and cushioning during traffic accidents, preventing secondary injuries. In addition to seat belts for both front and rear seats, cars are also equipped with airbag systems. In the event of a collision, the airbags automatically inflate and deploy to prevent occupants from hitting the car body, thereby protecting them.
