A system and method of activating protection means () in order to protect the physical integrity of an occupant of an aircraft () during an accident is provided. The protection means () are activated when, firstly the acceleration of said aircraft () along a particular axis (X, Y, Z) of the coordinate system of the aircraft () is greater than a first variable threshold, and secondly when the speed variation of the aircraft along said particular axis (X, Y, Z) is greater than a second variable threshold. The first variable threshold and the second variable threshold each vary as a function of the stage of flight of the aircraft () in such a manner as to be minimized during predetermined accident-prone stages of flight.

Method of activating protection means for protecting an occupant of an aircraft, and an aircraft implementing said method

An anti-crash seat () for a vehicle, the seat comprising a bucket () and a frame (), said bucket () being provided with a seat proper () and with a back () for receiving a person. Said seat () includes crash energy absorber means () and antivibration means (). The seat also includes inhibitor means () for inhibiting said antivibration means () so as to neutralize the antivibration means () when the seat () is subjected to acceleration towards the floor that is greater than a predetermined threshold.
