Abstract
An underframe for a passenger aircraft seat, the underframe including at least one element forming a front leg and at least one element forming a rear leg, and energy absorption structure that is active when a moving element of the seat moves relative to another element of the seat or of the floor of the aircraft cabin, under the effect of the seat being subjected to deceleration above a predetermined value. The energy absorption structure includes an energy absorption device including a male part that penetrates by force and with plastic deformation into an aperture in a female part. Either the female part or the male part is attached on and directly associated with the moving element, and the other part, i.e. the male part or the female part, is attached on and directly associated with the other element.
