The results of the tests on each device are presented in absolute terms, compared to baseline tests (no head/neck restraint) and normalized to the best performing device. Kinematic control of the head was also determined from analysis of the high-speed video recordings to obtain forward head excursion. Head and Neck Restraint Systems Head and Neck Support FHR Stand 21 Club Series III SFI 38. Head accelerations, neck loads and moments were analyzed to provide a comparison of the various systems ability to control head dynamics. The systems tested were the HANSĀ®, the Hutchens device, and the D-CEL device. Three tests with three samples of each system were performed to assess repeatability. In low or high speed conditions, a head and neck restraining system can be implemented to reduce forces exerted on a drivers (users) head and neck, in event of an accident. Three head/neck restraint systems were tested using a sled pulse with a 35 mph (56 km/h) velocity change and 50G peak deceleration. The goal of the tests was to examine the performance of the head/neck restraint without the influence of the seat or steering wheel. A six-point latch and link racing harness restrained the ATD. The tests were conducted at an impact angle of 30 degrees to the right, with a midsize male Hybrid III anthropomorphic test device (ATD) modified for racecar crash testing.

This paper evaluates the performance of a number of commercially available head/neck restraint systems using a stock car seating configuration and a realistic stock car crash pulse. Recent action by some racecar sanctioning bodies making head/neck restraint use mandatory for competitors has resulted in a number of methods attempting to provide head/neck restraint.
