Abstract

A rig was developed to permit impacts on a Hybrid III 50th-percentile male anthropomorphic test device (ATD) at selected velocities and head impact orientations in guided free-fall. This is to investigate the ability of a bicycle helmet to reduce angular head acceleration and subsequent brain injury in crashes, as well as the effects of helmets on neck injury. Helmets were able to reduce head linear acceleration significantly and angular accelerations in lateral impacts. There were no significant reductions in biomechanical predictors of neck injury risk in helmeted impacts as compared to un-helmeted impacts. At worst bicycle helmets do not appear to exacerbate head injury risks arising from angular acceleration or neck injury risks.
