Can Rear Seat Belts Be Left Unfastened?
1 Answers
Rear seat belts must not be left unfastened, as doing so not only seriously endangers the lives of front-seat occupants but also poses safety risks to oneself. In the event of a vehicle accident, without the protection of seat belts, rear-seat passengers may directly impact the front seatbacks, resulting in injuries to the nose, arms, neck, etc. The function of a car seat belt is to instantly tighten during a collision or emergency braking, securing the occupant firmly in the seat to prevent secondary collisions. Once the tightening force exceeds a certain limit, the force-limiting mechanism appropriately loosens the belt to maintain stable chest pressure. Thus, car seat belts serve to restrain movement and provide cushioning.
