Improved Design Criteria for Crash Helmets,

Abstract

A commercial motorcycle helmet was impact evaluated. The motorcycle helmet's impact protection is compared that of the SPH-4, the standard Army aviator's helmet. Drop tests, ranging from 0.91- to 2.44-meters, were used for the helmet testing by means of a helmet/headform free-fall device. The two examples of the helmet were subjected to 16 drop tests. Two of these drop tests resulted in a high level of transmitted force and acceleration which focuses on the inadequate thickness of the motorcycle helmet liner. The helmets did not provide adequate protection to prevent concussion or serious injury at all energy levels greater than produced at a 1-meter drop height. The tested helmets could be changed to provide adequate protection by doubling the thickness of the liner.
