An aircraft seat with head cushioning and anti-collision function

Abstract

The invention discloses an aircraft seat with head cushioning and anti-collision function, comprising a seat cushion, a backrest is arranged on one side of the top of the seat cushion, armrests are arranged in the middle of both sides of the backrest, and a headrest is arranged on the top of the backrest. The headrest includes a headrest body, and both sides of the headrest body are provided with headrest wings, and the headrest body and the headrest wings on both sides are movably connected by bolts. A supporting frame is arranged in the side of the pillow, and a buffer is provided between the side of the headrest and the supporting frame. Fasteners and connectors are provided on the bottom of one side, and vertical grooves and horizontal grooves are arranged in the fasteners, and the horizontal grooves are located at the lower right of the vertical grooves, and the vertical grooves A spring washer 1 is arranged at the bottom of the groove. Beneficial effect: the buffer zone can effectively prevent the passenger's head from colliding with other objects due to forward tilt.

Description

technical field [0001] The present invention relates to the technical field of seats, in particular to an aircraft seat with a head buffering and anti-collision function. Background technique [0002] In the 1970s, with the new technological revolution and the development of science and technology, a large number of alloy materials began to be used in aircraft seats. Aircraft seats are getting lighter and lighter, but the overloads experienced by aircraft seats have continued to the 9 G overload required in the 1952's. Since 1980, the normal landing speed of large jet airliners can reach 280 km / h, and the braking overload acting on the human body during the crash can reach 25G. The aircraft is still installed in accordance with the previous standard. chair. On January 25, 1990, Colombian Airlines Flight 052, a Boeing 707 with old-fashioned seats crashed on the mountains of Long Island near the New York Airport due to running out of fuel. The plane fell into two pieces unde...

Problems solved by technology

NTSB U.S. air accident investigators found a fact in the investigation that the seats designed in 1953 to withstand 9 G overloads did not play a very good role in protecting passengers during the crash. During the collision of G's plane, the supporting legs of the plane seat broke, causing the passenger to fly up from the seat fixed by the seat belt and hit the passenger in front

The fuselage and floor of the plane are still intact, and the safety belt of the plane is not broken, but the seat of the plane has fallen off, so the passengers who are tied to the seat with the safety belt, because the safety integrity of the plane seat is destroyed, lost The role of protecting passengers
