The present invention relates to a device (10, 20) for absorbing kinetic energy caused by an exceptional load, characterized in that it comprises: - an outer casing (100, 200a, 200b) configured to maintain integrity after the exceptional load, - a core (105a, 105b, 205a, 205b, 205c) made of a compactable material at least partially filling the outer casing, the core material becoming compacted under an exceptional load and absorbing some of the kinetic energy caused by the load, - at least one stiffness element (115, 215, 315, 40) incorporated into the core, and - a spreading element (110, 210, 310) comprising each stiffness element. The present invention also relates to an aircraft, a vehicle, an item of equipment and an installation comprising such a device. |
