Abstract
A force-limiting energy absorber comprises at least a first and a second elongated metal element (12, 13), being chosen out of a group consisting of a metal wire, a profiled metal wire, a metal strand, a bundle of untwisted metal wires and a metal rope. The elongated metal elements (12, 13) are deformable in its plastic region of its load-elongation diagram for absorbing energy. The load-elongation diagram and elongation at fracture of the first elongated metal element (12) is different from the load elongation diagram and elongation at fracture of the second elongated metal element (13).
