Influence of standing or seated pelvis on dummy responses in rear impacts

► We evaluated the influence of dummy pelvis on occupant responses in rear sled tests. ► The seated pelvis involves only a small portion of the upper leg molded into the vinyl skin of the pelvis and does not limit leg rotation. ► Matched testing at 10-40 km/h showed no significant difference in occupant kinematics or biomechanical responses with the standing and seated pelvis. ► Hybrid III dummy with the seated pelvis is suitable for FMVSS 301 and other rear impact tests.
