Anti-crash energy-absorbing aero seat with ring-shaped dampers

Abstract

The invention relates to an anti-crash energy-absorbing aero seat, which belongs to the technical field of aero seats. The anti-crash energy-absorbing aero seat comprises a seat board (4), a seat back (8), front legs and rear legs, wherein the front legs and the rear legs are similar in structure and adopt buffering structures; the front legs are perpendicular to the ground, the lower ends of thefront legs are fixed on the ground, and the upper ends of the front legs are connected with the seat board (4) through a guide track slideway structure; the rear legs are obliquely laid towards the front upper part, the lower ends of the rear legs are hinged on the ground, and the upper ends of the rear legs are connected with the seat board (4) in a hinged way; the seat back (8) is divided into an upper part and a lower part which are connected through a ring-shaped damper (5) in a hinged way; and the seat board (4) and the seat back (8) are connected through a ring-shaped damper (5) in a hinged way. The anti-crash energy-absorbing aero seat, provided by the invention, can buffer and absorb energy after a plane crash, generate ideal structural distortion, reduce the impact force undergone by passengers and protect the safety of the passengers as much as possible.

Description

technical field [0001] The invention relates to an anti-crash energy-absorbing aviation seat with an annular damper, which belongs to the technical field of aviation seats. technical background [0002] When a civil plane lands abnormally and hits the ground, its course and vertical speed decrease suddenly, and the occupant is affected by inertia, which produces a vertical and course impact force on the seat. The impact force reacts on the human body, causing damage to the human spine and neck Dangerous, causing fatal injury to human body. The only way to reduce this impact is to design special aviation seats. In the early 1960s, the U.S. Aviation Safety Engineering and Research Department began to investigate the causes of occupant injuries caused by aircraft crashes. The investigation results pointed out that: during the crash, the aviation seat must be able to fully and reliably restrain the occupants while maintaining connection with the aircraft structure; The loads g...

AI Technical Summary

Problems solved by technology

They can both act as a buffer, but only absorb vertical kinetic energy through the struts, and have no effect on directional kinetic energy

In addition, the current aviation seats have other deficiencies: there is no special design for the shape of the impact deformation, so that the seat deforms in a way that is conducive to protecting the occupants; after the seat is impacted, only the chair legs are compressed or crushed, The occupant's legs are in danger of being impacted; the occupant will lean forward due to the inertial force of the yaw, and his head will hit the front seat, causing injury
