Application design of piezoelectric effect in cabin seat belt status indication

Abstract

During the special operation stage of the aircraft, if the passengers did not fasten their safety belts in accordance with the requirements, it may bring unexpected injury, resulting in unnecessary losses. So if there is a corresponding system can help the crew to accurately confirm the state of the safety belts of the passengers under special circumstances, what we said before can be avoided. The seat belt status indicator system is designed based on the piezoelectric effect can help the crew to know the state of the safety belt clearly, to ensure the effectiveness of their work.
