What is a primary function of the seat belt extender?

The primary function of the seat belt extender is to accommodate larger passengers. This tool is designed specifically to provide an additional length to the standard seat belt, allowing passengers who may not fit comfortably or safely into the standard belt due to their size to secure themselves properly. Ensuring that all passengers can buckle their seat belts is crucial for safety during flights, as it helps to prevent injuries in case of turbulence or an emergency.

While enhancing passenger comfort and securing passengers during takeoff are important aspects of passenger experience and safety, the seat belt extender specifically addresses the need for individuals who cannot utilize a standard seat belt comfortably. Keeping the aisle clear, while important for safety and access, is not a function related to the seat belt extender's design or purpose.
