This is a conceptual project in which I sought to improve the current design of the mechanism of opening and closing the seat belts of an aircraft.
Not a few people find it difficult to open seat belts under normal conditions, so its difficulty can be increased in situations of emergency.
The system is released automatically if the crew members (flight attendants and / or captains) give the evacuation signal. It is also released after a time, if the aircrafts suffered impacts of various gravities (similar to how the seat belts with airbags work)
