Development of Anthropometric Analogous Headforms

The overall goal of the CTI study is to design three manikin headforms--small, midsized, and large--for use in military ejection seat and crashworthiness testing, as well as retention and fit assessment, of helmet and head-supported devices. The headforms will be applicable to military male and female aviator populations. 14. Sponsonng Agency Code UMTRI conducted a literature search and review to help establish the most appropriate design specifications for headform characteristics and properties. The U.S. Army Anthropometric Survey (ANSUR) database was selected from the literature review as the most suitable existing database for use in design of headforms. It includes data for 1,774 men and 2,208 women. An ANSUR data subset, obtained from the U.S. Army Natick Research, Development and Engineering Center, includes, for each subject, 16 head and face traditional anthropometric variables and the- (continued on next page)
