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

摘要

The present invention relates to a method for activating a means of protection (1) with the aid of a means of activation (3) in order to protect the physical integrity of an occupant of an aircraft (10) during an accident, the aircraft having an orthonormal system comprising a longitudinal axis (x), a transverse axis (y) and an elevation axis (z), during which it is active, said protection means (1) when, on the one hand, the acceleration of said aircraft (10) according to an axis (x, y, z) of the frame of reference of the aircraft (10) is greater than a first variable threshold and, on the other hand, the variation of the speed of the aircraft along said axis (x, y, z) is greater than a second variable threshold, the first variable threshold and the second variable threshold, each of which varies as a function of the flight phase of the aircraft (10) so as to be minimized during the phases of flight accident-prone predetermined.
