“…The other five rib fractures were associated to the standard belt. These findings are in line with those reported by Forman et al (2009). The paucity of pediatric thoracic data under the same belt conditions does not allow drawing any conclusion on the ability of this adult PMHS to represent the behavior of a pediatric chest.…”

“…Using a parametric MADYMO study, Kent et al (2007) reported that there are likely different combinations of force-limiting and pretensioning belts that can decrease thoracic injury risk with no increase in forward head excursion (or with an acceptable one). Forman et al (2009) analyzed the performance of different restraints using adult PMHSs in simulated rear seat frontal impacts at 48 km/h. This study shows that a progressive force-limiting pretensioning belt can decrease maximum normalized chest compression (PT+FL: 29 ± 3%; standard belt: 35 ± 9%) and number of rib fractures (FL+PT: 10 ± 8 fractures; standard belt: 18 ± 9 fractures) when compared to a standard belt.…”

“…Several sets of sled test data using overweight post mortem human surrogates (PMHS) (Forman et al 2009a; Forman et al 2009b; Michaelson et al 2008) and standard anthropomorphic test devices (ATD) (Forman et al 2008) were reported, in which the subjects were seated in the rear seat. Since no test data of overweight PMHS in the front seat is available at present, the test data at the rear seat (Forman et al 2008; Forman et al 2009a; Forman et al 2009b; Michaelson et al 2008) were used for the validation of the standard and overweight dummy models.…”

The objective of this study was to examine the role of body mass and subcutaneous fat in injury severity and pattern sustained by overweight drivers. Finite element models were created to represent the geometry and properties of subcutaneous adipose tissue in the torso with data obtained from reconstructed magnetic resonance imaging datasets. The torso adipose tissue models were then integrated into the standard multibody dummy models together with increased inertial parameters and sizes of the limbs to represent overweight occupants. Frontal crash simulations were performed considering a variety of occupant restraint systems and regional body injuries were measured. The results revealed that differences in body mass and fat distribution have an impact on injury severity and pattern. Even though the torso adipose tissue of overweight subjects contributed to reduce abdominal injury, the momentum effect of a greater body mass of overweight subjects was more dominant over the cushion effect of the adipose tissue, increasing risk of other regional body injuries except abdomen. Through statistical analysis of the results, strong correlations (p < 0.01) were found between body mass index and regional body injuries except neck injury. The analysis also revealed that a greater momentum of overweight males leads to greater forward torso and pelvic excursions that account for higher risks (p < 0.001) of head, thorax, and lower extremity injury than observed in non-overweight males. The findings have important implications for improving the vehicle and occupant safety systems designed for the increasing global obese population.
