Effects of obesity on seat belt fit
Introduction: Obesity has been shown to increase the risks of some types of injury in crashes. One way in which obesity may increase injury risk is by changing the routing of the belt relative to the underlying skeletal structures. Methods: Belt fit was measured in a laboratory study of 54 men and...
Explaining state-to-state differences in seat belt use a multivariate analysis of cultural variables.
There is considerable variation in seat belt use within the United States despite extensive evidence that the use of seat belts saves lives. Previous studies have identified some important factors that affect belt use rates, including gender, age, race, vehicle type, seat-belt enforcement laws, and...
LATCH usability in vehicles
This project investigated the usability of Lower Anchors and Tethers for CHildren (LATCH) hardware by measuring LATCH implementations in 98 2011 or 2010 model-year vehicles. ISO and SAE LATCH usability rating systems were used to assess all vehicles using data from the second row left position....
Fetal outcome in motor-vehicle crashes effects of crash characteristics and maternal restraint.
This project was undertaken to improve understanding of factors associated with adverse fetal outcomes of pregnant occupants involved in motor-vehicle crashes. In-depth investigations of crashes involving 57 pregnant occupants were performed. Maternal and fetal injuries, restraint information,...
Quantifying dynamic mechanical properties of human placenta tissue using optimization techniques with specimen-specific finite-element models
Motor-vehicle crashes are the leading cause of fetal deaths resulting from maternal trauma in the United States, and placental abruption is the most common cause of these deaths. To minimize this injury, new assessment tools, such as crash-test dummies and computational models of pregnant women,...
Estimation of seatbelt and frontal-airbag effectiveness in trucks: U.S. and Chinese perspectives.
The objectives of this study were (1) to estimate the effectiveness of seatbelts and driver airbags for mitigating medium- and heavy-truck driver injuries, and (2) to discuss the implication of these estimates with respect to truck-driving conditions in the U.S. and China. U.S. data showed that...
Documenting how states recently upgraded to primary seat belt laws
States with primary seat belt enforcement laws consistently have higher observed daytime belt use rates than secondary law States. Secondary belt law States, on the other hand, consistently have more occupant fatalities who were not restrained than primary law States. Since the year 2000, 14 States...
Modeling the impact of rescinding Michigan’s primary and secondary seatbelt laws on death and injury from passenger vehicle crashes
Seatbelts are the most effective method of decreasing fatal and non-fatal motor vehicle crash injury. Advocacy groups have recently been successful enacting repeals of mandatory motorcycle helmet laws in several states. In some states, this has prompted renewed efforts aimed at repealing mandatory...
