TY - JOUR PY - 1976// TI - Non-perpendicular impacts - an experimental study on crash helmets JO - Proceedings of the International Research Council on the Biomechanics of Injury conference A1 - Aldman, B.

Due to friction, this can result in angular accelerations of the head which may prove to be injury-producing. A test method has been developed with the purpose of investigating the effect of different helmet shell materials on the kinematics of the head at impact. The test device utilizes a dummy head and neck attached to a rail-guided free-falling carriage. Simulated road surfaces can be attached to a rotating disc. Linear and angular head accelerations in three perpendicular directions as well as rotation and lateral flexion of the neck have been recorded. Results from a preliminary test series are presented with reference to some published tolerance levels. (a).
