Abstract
In order that the acceleration suffered by the occupant (O) of an aircraft, particularly a rotary-wing aircraft seat in the case of an accident remains below a humanly withstandable limit, no matter what the size of said occupant, a seat is proposed in which a height regulation of the pan or bucket (16), in which the occupant is received, also has the effect of modifying the inclination of the energy absorbers (38). Thus, the vertical component of the retaining force exerted on the pan (16) by said absorbers decreases with the size of the occupant, which leads to the desired result.
