Aircraft seat and in particular a rotorcraft seat with an energy absorbing device automatically adjustable in terms of the passenger weight

摘要

So that the acceleration experienced by the occupant (O) of an aircraft seat, especially of a rotor craft seat, in the event of an accident, remains lower than a humanly tolerable limit, whatever the size of this occupant, a seat is proposed in which height adjustment of the seat pan (16), on which the occupant is accommodated, also has the effect of altering the inclination of the energy absorbers (38). Thus, the vertical component of the retention force exerted on the seat pan (16) by these absorbers reduces with the size of the occupant, which obtains the desired result.
