1, principle: The working principle of the intelligent anti-fall airbag with belt protection is to detect the movement state of the wearer by sensors. When it is detected that the wearer falls abnormally, the airbag will quickly inflate and wrap the waist of the wearer, thus slowing down the impact force and reducing the harm to the body.

2. Manufacturing method: The manufacturing method of intelligent anti-fall airbag with belt protection is to integrate sensors, microcontrollers, micro air pumps and other components into the belt, and transmit data to terminal devices such as mobile phones through wireless transmission. When it is detected that the wearer falls abnormally, the micro air pump will automatically start and fill the air bag with gas, so that the air bag will expand rapidly, thus playing a protective role.
