ENERGY ABSORBING SYSTEM AND HELICOPTER SEAT CONTAINING ENERGY ABSORBING SYSTEM Russian patent published in 2021 - IPC B64D11/06 B64D25/04 B60N2/427 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aircraft engineering, in particular to energy-absorbing systems, used mainly for helicopter seats, as well as to the structure of a helicopter seat containing an energy-absorbing system. The energy-absorbing system includes the first stage of energy absorption, consisting of a damper tube with damper shafts, and the second stage of energy absorption, consisting of energy-absorbing inserts and sliding bushings installed on cylindrical lower and upper guides along which the sliding brackets with the seat of the chair slide in case of rupture breaking element. The first stage of energy absorption additionally contains a sleeve that provides spatial orientation of the damper tube. The helicopter seat includes support legs with the energy-absorbing systems mentioned above, on which the seat of the seat is mounted by means of hinge brackets.

EFFECT: increasing the reliability of the structure of the energy-absorbing system and the chair as a whole, increasing safety due to the effective damping of the impact energy.
