Abstract
A system for protecting a head of a wearer from an impact force includes a helmet defining an interior space for housing the head and at least one damper coupled to the helmet at a first end and extending therefrom along a longitudinal axis to a second end. The damper includes of a plurality compressible energy damper elements concentrically arranged about the longitudinal axis. The plurality of compressible energy damper elements includes an outer damper element and an inner damper element. The outer damper element surrounds the inner damper element and extends to the second end of the damper. The outer damper element has a first uncompressed length and the inner element has a second uncompressed length that is different from the first uncompressed length. Alternatively, the plurality of compressible damper elements are concentrically arranged and are arranged end to end in series.
