Recent design characteristic changes in a small segment of production passenger car front seats have focused attention on the influence of seat back strength on occupant kinematics and potentially injurious loads placed on occupants during rear end collisions. The results of the sled tests indicated that stiffer seats do not have any consistent advantages over yielding seats for the complete range of speeds tested. When the production seats were modified to obtain higher seat back stiffness, higher responses were seen at the neck, thoracic spine, and lumbar spine. The other, stiffer production seats of different design also showed no consistent improvement in occupant protection across the speed range. Even a seat with a head restraint located closer to the center of gravity of the occupant's head did not perform better than the baseline seat. Throughout the testing, the most sensitive response to seat design and crash severity was the lower neck extension moment.
