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 ).
