Abstract:Validation of new crash test dummies for rear-end collision testing requires human response data from pertinent test situations. Eleven human volunteers were exposed to 23 low-speed rear impacts to determine human response in well-defined test seats, and to quantify repeatability, variability and the effect of seat design on human response.

The results showed vertical motion of the volunteers’ H-point caused by ramping up along the seat, and an upward motion of the volunteers’ torso and head. The latter was caused by a combination of ramping up along the seatback and straightening of the thoracic kyphosis. During the first 100 ms, the volunteers flexed their necks. Thereafter, the volunteers extended their necks. These new data have proven to be useful in validation of rear-impact dummies.
