Sizing Head Forms: Design and Development 960455

This report describes the creation of anthropometric head forms. These head forms represent the population of U.S. children aged 2 to 18, and they can be used to develop bicycle helmets which fit the entire range of that population.A Cyberware digitizer was used to collect 3-D points on the heads of 1035 children. Six traditionally measured dimensions were also taken. The data were grouped into four size and shape categories. Statistical techniques were used to summarize the shapes of the heads in each of the categories. The resulting three-dimensional forms were physically rendered using an automated milling machine.
