Abstract:
An energy damper comprising:a plurality of break lines having different tensile strengths to sequentially part as the tensile strengths of said break lines are exceeded to absorb and dissipate energy; andan elongate strength member to be connected between a component and a source of inertial drag, said break lines sequently parting to absorb and dissipate energy during displacement of said component from said source of inertial drag, said strength member being connected between said displaced component and said source of inertial drag to limit said displacement, said strength member having greater tensile strength than individual ones of said break lines and being arranged in a serpentine shape with said break lines connected in sets to said strength member, and different ones of said sets of break lines being each connected across separate turns in said serpentine-shaped strength member and having said different tensile strengths.
