The development of modern smart restraint systems requires access to human surrogates with a biofidelic performance, which includes details on timing and local deformations. Therefore volunteer head neck responses for oblique impacts from the Naval BioDynamics Laboratory were re-analysed using a method developed by Thunnissen. Response parameters were chosen to allow a straightforward comparison of crash dummies with volunteers. The response parameters are time histories of 3D kinematics relative to the sled of the head centre of gravity and the anatomical defined T1. Kinematics of the head relative to a rotating T1 and all six occipital load components are presented. A general applicable method to calculate 3D head flexion and twist is developed. The result is a set of time history corridors and mean peak ± standard deviation windows, which can be used in the evaluation of human surrogates in addition to existing frontal and lateral response specifications.
