Background

In the seventies of the last century, with the development of new technological revolution and technology, a great deal of alloy materials have come to be used for seats of airplanes. Aircraft seats are becoming lighter in weight, but the overload experienced by aircraft seats has continued for the 9G overload required in the 1952 s. Since 1980, the normal landing speed of a large jet airliner can reach 280 km/h, the brake overload acting on a human body during crash can reach 25G, and the airplane still has a seat which is installed according to the previous standard and bears the static load of 9G. In 25.1.1990, the 052 flight of columbia aviation, a boeing 707 with an old seat crashed on the mountain of the long island near the new york airport due to the exhaustion of fuel, the airplane was dropped into two parts under violent impact, 85 passengers survived and 73 passengers died. The NTSB American air crash investigator found a fact in investigation that the seat which can bear the overload of 9G according to the design standard in 1953 does not play a good role in protecting the passenger during the crash of the airplane, and the support legs of the seat of the airplane are broken during the crash of the airplane with more than 15G, so that the passenger flies on the seat fixed by the safety belt and collides with the passenger in front. The body and the floor of the airplane are still intact, the safety belt of the airplane is not broken, but the seat of the airplane is fallen off, so that the passenger who uses the safety belt to bind on the seat loses the function of protecting the passenger because the safety integrity of the seat of the airplane is damaged.
