Quantifying the whole body response of ATD (anthropomorphic testing device) is important to study the behavior of belted occupant. In a previous study we studied the forward excursion of ATD, PMHS (Post Mortality Human Subject = Cadaver) with standard 3-point belt and Human Volunteer with energy absorbing shoulder belt, and concluded that the excursion of a human volunteer with tensed muscles in high speed frontal impact is less than the forward excursion of PMHS. In this work, we examined the behavior of a relaxed Human Volunteer with Inflataband (an airbag equipped seat belt) in a high speed impact test which conducted in 1970`s and PMHS and ATD with Air Belt. We compared the result with previous study and also study the response of THOR dummy. Result demonstrated the forward excursion of relaxed human volunteer is smaller than PMHS, echoing the results from the previous research.
