  Impact Performance Comparison of Type II Safety Helmets with and without Dedicated Mechanisms for Brain Protection
  Author(s): Michael Bottlang*, Stanley Tsai, Tristan Miller and Steven Madey
  
  The latest generation of safety helmets features improved impact liners to meet Type II lateral impact requirements of standard ANSI Z89.1. Several manufacturers have also introduced technologies to dampen rotational forces known to cause brain injury. This study evaluated the impact performance of these novel helmets. Seven Type II-rated helmets were tested, four of which included technologies for brain protection from rotational forces, namely Impact Armor, MIPS, Koroyd and WaveCel. Impact performance was tested in three scenarios: lateral impacts according to ANSI Z89.1, crown impacts according to EN-12492 and oblique impacts representative of falls. For lateral impacts, a helmeted headform was dropped onto an anvil with 31 J impact energy, impacting the helmet front, side and back to assess impact acceleration. For crown impacts, a striker was dropped onto the helmet cro.. View more»
