Patent ID: 8562075

Claim:
An energy absorber element comprising: an absorber portion having a first elongate element and a second elongate element, wherein each of the first and second elongate elements includes at least four straight-line segments spaced apart in an elevation direction and being mutually parallel to one another, and a plurality of semi-circular segments such that at each of the successive straight-line segments are connected together by one of the semi-circular segments, wherein the first and second elongate elements are connected at a first and second distal end to form a single-piece continuous loop; a first anchor point having a first anchor aperture and fixedly secured to the first distal end of the absorber portion so that the first anchor point is stationary with respect to the absorber portion; and a second anchor point having a second anchor aperture and fixedly secured to the second distal end of the absorber portion so that the second anchor point is stationary with respect to the absorber portion, wherein the first and the second elongate elements deform elastically when subjected to traction in the elevation direction below a predetermined threshold and plastically when subjected to traction in the elevation direction above the predetermined threshold.
