While studies replicating mid-size and\n                    upright fore-aft seated occupants are numerous, experiments with post-mortem\n                    human subjects (PMHS) with obese and reclined occupants are sparse. The\n                    objective of this study was to compare the kinematics of the head-neck, torso\n                    and pelvis, and document injuries and injury patterns in frontal impacts. Six\n                    PMHS with a mean body mass index of 38.2 \u00b1 5.3 kg\/m&lt;sup&gt;2&lt;\/sup&gt; were equally\n                    divided between upright and reclined groups (seatback: 23\u00b0, 45\u00b0), restrained by\n                    a three-point integrated belt, positioned on a semi-rigid seat, and exposed to\n                    low and moderate velocities (15, 32 km\/h). Data included belt loads, spinal\n                    accelerations, kinematics, and injuries from x-rays, computed tomography, and\n                    necropsy. At 15 km\/h speed, no significant difference in the occupant kinematics\n                    and evidence of orthopedic failure was observed. At 32 km\/h speed, the primary\n                    difference between the cohorts was significantly larger Z displacements in the\n                    reclined occupant at the head (190 \u00b1 32 mm, vs. 105 \u00b1 33 mm p &amp;lt; 0.05) and\n                    femur (52 \u00b1 18 mm vs. 30 \u00b1 10 mm, p &amp;lt; 0.05). All the moderate-speed tests\n                    produced at least one thorax injury. Rib fractures were scattered around the\n                    circumference of the rib-cage in the upright, while they were primarily\n                    concentrated on the anterior aspect of the rib-cage in two reclined specimens.\n                    Although MAIS was the same in both groups, the reclined specimens had more\n                    bi-cortical rib fractures, suggesting the potential for pneumothorax. While not\n                    statistical, these results suggest enhanced injuries with reclined obese\n                    occupants. These results could serve as a data set for validating the response\n                    of restrained obese anthropometric test device (ATDs) and computational human\n                    body
