Abstract
An emergency parachute 1 comprises an umbrellalike body 10 which has an outer cloth 11 and an inner cloth 12 and is formed in bag shape, an inflator 15 which is inserted in an opening part 121 of the inner cloth 12 and fills a gas into the umbrellalike body 10, a suspension band 16 which holds a person, and a rope set 17 which couples the umbrellalike body 10 and the suspension band 16. The outer cloth 11 and the inner cloth 12 of the umbrellalike body 10 are coupled by a plurality of coupling cords 14, and when the gas is filled, the outer cloth 11 and the inner cloth 12 generate curved surfaces toward the same direction. Also the inflator 15 ignites an ignition device by pulling a tractive cord 30, and a gas producing agent within a gas producing chamber is exploded and the gas is jetted from a jet.
