Patent ID: 8662265

Claim:
An energy absorber for an aircraft, the energy absorber comprising: a first energy absorber element and a second energy absorber element, both for absorption of an acceleration energy by plastic deformation; and a housing including a first cover plate and a second cover plate parallel to the first cover plate, wherein the energy absorber elements are configured to undergo plastic deformation within the housing between the first cover plate and the second cover plate; and wherein the second energy absorber element is arranged parallel to the first energy absorber element and abuts the first energy absorber element; wherein the first energy absorber element comprises a first longitudinal slit; wherein the second energy absorber element comprises a second longitudinal slit; and wherein the housing further comprises an intermediate wall arranged in the area of the first and second longitudinal slits, the intermediate wall substantially extending between the first cover plate and the second cover plate and subdividing the housing into at least first and second chambers.
