Title and Subtitle: Evaluation of Head Impact Kinematics for Passengers Seated Behind Interior Walls

Report Date: May 1992

Authors: Gowdy, V. and DeWeese, R.

Abstract: Federal Aviation Regulations for crashworthy seats include the Head Injury Criteria (HIC) as part of the pass-fail performance specifications. For passenger seats located behind interior walls to meet this requirement, the dynamics of head impact with the wall must be evaluated from a system approach. Procedures for conducting system tests and analyzing the head motion of an anthropomorphic test dummy (ATD) are described. Analyses of head kinematics from dynamic impact tests with a lap belt restrained ATD are presented.
