Individuals using wheeled mobility devices (WMDs) often use them as motor vehicle seats during transportation. Wheelchair occupant restraint systems (WORSs), consisting of upper torso and pelvic restraints, are usually mounted to the structure of transit vehicles to secure individuals within their wheelchair seats. This preliminary study attempts to evaluate the use and satisfaction of currentl...

PURPOSE Operating or riding on farm equipment is one of the leading causes of farm-related injuries and fatalities among children and adolescents. The aim of this study is to examine environment, crash, vehicle, and occupant characteristics and the probability of injury, given a crash, in youth under age 18 on farm equipment. METHOD Data from the Departments of Transportation on farm equipmen...

Abstract: In this paper, new front-end structures (smart) are proposed to improve vehicle frontal impact. The work carried out in this paper includes developing and analysing mathematical models of vehicle-to-rigid barrier offset frontal impact using fixed and extendable smart front-end structures with piecewise linear characteristics. In these models, vehicle components are modelled by lumped ...

The purpose of our study was to evaluate the impact of shoulder belt use on motor vehicle crash ejection, morbidity and mortality. We analyzed motor vehicle crash records linked to hospital inpatient data for front seat occupants of passenger cars in Utah between 1994 and 1996 (n = 103,035). Stochastic simulations were used to adjust for possible seatbelt misclassification. There were 276 (0.3%...

in the present paper, employing a complete model of a passenger car, contribution of various components and assemblies in the frontal crash energy absorption is determined. thickness of components with more remarkable contribution is increased to improve the occupant safety. furthermore, effects of substituting the metallic bumper with one fabricated from gmt materials on the frontal crash beha...

The objective of this study is to investigate the effects of obesity on occupant responses in frontal crashes using whole-body human finite element (FE) models representing occupants with different obesity levels. In this study, the geometry of THUMS 4 midsize male model was varied using mesh morphing techniques with target geometries defined by statistical models of external body contour and e...

DESCRIPTION An assessment of the independent effectiveness of primary care interventions to increase the proper use of child safety seats, booster seats, and lap-and-shoulder belts to prevent motor vehicle occupant injuries (MVOIs) and to prevent alcohol-related MVOIs in adolescents and adults. METHODS The U.S. Preventive Services Task Force reviewed evidence on the effectiveness of counselin...

OBJECTIVE To determine the effect on fatality rates in crashes of installation of shoulder belts in automobile back seats. METHODS During 1988-96, fatalities to rear outboard seat occupants of passenger cars, classified by age of occupant and vehicle curb weight were matched to data on model year in which shoulder belts became standard equipment. The same data were obtained from the same year...
