At present, elevators lack of comprehensive security system. Once the elevator drop occurs, the protection measures that people can take is very limited. For this, we designed a elevator safety belt. When the elevator is falling down, the people inside the elevator can tie it immediately to avoid getting hurt. Our elevator safety belt equipped a neck support device and a nursing of spinal device, which could decrease the hurt during the process of fast falling effectively. It can greatly decrease the death rate of elevator accident.
