Can a seat-belt be a pulley?

A seatbelt can function as a type of pulley system in certain contexts, such as in a vehicle's restraint mechanism. In this case, the seatbelt is integrated with a retractor that allows it to extend and retract, similar to how a pulley allows movement along a rope. However, it's important to note that while it may share some mechanical functions, a seatbelt is primarily designed for safety rather than as a traditional pulley.
