Mechanisms of Seat Belts Seat belts restrain occupants using high‑strength webbing anchored to the vehicle, a retractor that locks during sudden deceleration or rapid pull, pretensioners that remove slack in milliseconds at crash onset, and load limiters that let the belt pay out in a controlled way to manage chest forces. Together with sensors and …
What Is the Viscous Coupling in AWD?
