Twelve elderly female rheumatoid arthritis patients (mean age = 65.5 +/- 8.6 yr) were assessed rising from an instrumented Eser Ejector chair under four conditions: high seat (540 mm), low seat (450 mm), with and without the ejector mechanism operating. Sagittal plane motion, ground reaction forces, and vertical chair arm rest forces were recorded during each trial with the signals synchronised...

We study how the seat value perceived by consumers attending an event in a theater/stadium, depends on the location of their seat relative to the stage/field. We develop a measure of seat value, called the Seat Value Index, and relate it to seat location and consumer characteristics. We implement our analysis on a proprietary dataset that a professional baseball franchise in Japan collected fro...

One hundred ninety-five rear impacts with both front- and rear-seat occupants in the struck car, where at least one occupant sustained permanent disability, were selected for study. There was a significantly higher disability risk for the female rear-seat occupant compared with the male driver. Furthermore, a higher risk was found for female rear-seat occupants compared with female front-seat p...

A new approach to driver seat-position modeling is presented. The equations of the Seating Accommodation Model (SAM) separately predict parameters of the distributions of male and female fore/aft seat position in a given vehicle. These distributions are used together to predict specific percentiles of the combined male-andfemale seat-position distribution. The effects of vehicle parameters—seat...

a motor vehicle seat belt use law for the driver and front-seat passenger was implemented in taiwan on june 1, 2001. the purpose of this study was to determine the effect of motor vehicle seat belt use on the severity of traumatic brain injuries because of motor vehicle accidents.data were collected from 27 major teaching hospitals four years before june 1, 2001 and until may 31, 2013. a total ...

OBJECTIVE Observe and report seat belt use among children transported in belt-positioning booster seats. DESIGN We conducted a cross-sectional, observational survey of children transported in motor vehicles between 2006 and 2007. While drivers completed a survey reporting the child's age, weight and gender, and the driver's age, gender, race, income, education, and relationship to the child; ...

OBJECTIVES Traffic crashes are a leading cause of deaths and injuries in Pakistan. The World Health Organization (WHO) estimates that approximately 30,131 people die in road crashes annually on Pakistani roads (WHO 2013). The use of seat belts can be effective in reducing road crash fatalities in Pakistan but under existing seat belt laws, seat belt use is mandatory only for drivers and is limi...

INTRODUCTION In this paper, we show that FARS data can be a comparable alternative to observational NOPUS data in estimating seat belt use in the United States once we correct for sample selection bias. RESULTS Based on assumptions of independence for seatbelt choice, we establish a lower and upper bound for seatbelt usage rates, and find that once we correct for sample selection bias, the se...

To assess the efficacy of occupant protection systems, the authors measured the mortality reduction associated with air bag deployment and seat belt use for drivers involved in head-on passenger car collisions in the United States. They used a matched case-control design of all head-on collisions involving two passenger cars reported to the Fatality Analysis Reporting System in 1992-1997, and d...
