Test results indicated that all resilient linear helmets (six of seven helmets tested) produced similar peal axial compressive forces at the neck. The only helmet with a nonresilient crushable foam liner that was tested produced much larger axial compressive neck forces at the higher tackling block impact speeds. Two injury reference curves for axial compressive neck loading are described based on measurements made with the GM Hybrid III dummy, and a procedure for assessing axial compressive neck load impulses relative to either injury reference curve is given. Because of the limited information relating neck loadings measured with the GM Hybrid III dummy to known human neck injuries, these injury references should be used only as guides in interpreting data obtained with the dummy. Neck injuries that might result from bending, shearing, axial tension, or combinations of these loadings are not applicable to either of these axial compressive force references. (Author)
