ABSTRACT OF THE INVENTION An energy absorber (or arrestor) working on the principle of straining an elongated element by pulling it through a tortuous path over rotatable rollers and characterised by the element being of flexible laminar construction. The flexibility of this element allows it to be formed into a conveniently small coil, the diameter of which being that of an equivalent section rigid element divided by the number of laminae. The rollers, similarly reduced in diameter, are arranged into two opposed banks which temporarily divide the element into two equal and opposite laminar groups, the angular reactions of which counterbalance each other. The normally haavily loaded exit rollers are substantially assisted by contact with remote support bearings. The end of the element is anchored by entrapping two equal groups of laminae, utilising the strain energy principle and retaining the use of the full tensile area.
