Which component is NOT part of a seatbelt?

• A. Coupling Unit
• B. Anchor Fitting
• C. Wheel Assembly
• D. Seat Belt

Answer: (C)

The component that is not part of a seatbelt is the wheel assembly. A seatbelt system primarily consists of several key components designed for safety: the coupling unit, which connects different parts of the seatbelt system; the anchor fitting, which secures the seatbelt in place to the vehicle's structure; and the seatbelt itself, which is the belt that restrains the occupant during a collision.

The wheel assembly, on the other hand, does not relate to the operation or functionality of a seatbelt. It typically pertains to components associated with a vehicle's wheels, such as the hub, tire, or related mechanisms. Therefore, it does not have a role in the configuration or effectiveness of a seatbelt system, making it the correct choice in identifying which component is not part of a seatbelt.
