It has been discussed one of the most important motor accidents to whiplash injury due to the low speed rear-end collision. Whiplash injury is one of injuries caused by automotive rear-end impacts, but occupies much frequency of occurrence and the high cost for treatments. For these reason, the test procedures and the evaluation criteria of seats and head restraints have been devised by IIWPG (International Insurance Whiplash Prevention Group) to prevent neck injury in moderate and low speed rear-end impacts. This paper describes a theory of whiplash injury in low-speed rear impact and the effect of head restraint systems. seat mechanism with sled using a BioRID-Ⅱ. We studied comparison of the injury criteria in order to improve whiplash injury.

The IIWPG (International Insurance Whiplash Prevention Group) dynamic test and FMVSS (Federal Motor Vehicle Safety Standard) 202a dynamic test evaluate occupant's neck injury about head restraint at the low speed rear-end car accident. However two tests have the different to acceleration pulse, test procedure, dummy type and injury criteria for evaluation at sled. The IIWPG dynamic test has the injury criteria such as T1 (Thoracic 1) acceleration, head contact time, neck shear (Fx), and neck tension (Fz). And FMVSS 202a dynamic test has the injury criteria such as HIC₁?, chest to head rotation angle. This paper compared test procedure, head restraint's evaluation method of IIWPG head restraint dynamic test and FMVSS 202a dynamic test. And as the two tests perform at sled, we compared interrelation of the injury criteria such as Head X Acceleration, T1 Acceleration and Upper Neck Force which are acquired in common.
