OBJECTIVES The purpose of this work was to investigate the fitness of the existing truck seats for Bangladeshi truck drivers and suggest a guideline for drivers' seats based on their anthropometry. METHODOLOGY In this study, eight anthropometric measurements of 120 Bangladeshi truck drivers and seven seat dimensions of ninety trucks of three brands namely, TATA, ASHOK LEYLAND, and ISUZU were ...

OBJECTIVE We sought to determine the age at which US parents first turned their child's car seat to face forward and information sources used to make that decision at the time of the release of the 2011 guidelines for child passenger safety and 30 months later. METHODS We administered 2 separate cross-sectional Web-based surveys of nationally representative panels of US parents in May 2011 an...

PROBLEM It has been established that graduated licensing systems lead to crash reductions among beginning drivers. What is the contribution of the various components of graduated licensing to these reductions, and how can their effectiveness be increased? METHOD Literature review and synthesis. RESULTS Extended learner periods, nighttime restrictions, and passenger restrictions have contrib...

This paper used the Hyper Mesh and LS-DYNA software to establish a dummy-seat finite element simulation model. The head, chest and neck injury of the dummy were analyzed respectively in the frontal impact and rear impact. It was indicated that modification of seat was needed to meet the requirements. The simulation results showed that the original model cannot provide effective protection for t...

In this paper a nonlinear quarter car suspension-seat-driver model was implemented for optimum design. A nonlinear quarter car model comprising of quadratic tyre stiffness and cubic stiffness in suspension spring, frame, and seat cushion with 4 degrees of freedom (DoF) driver model was presented for optimization and analysis. Suspension system was aimed to optimize the comfort and health criter...

Seat belt legislation appears to have reduced mortality from, and the incidence of, serious head and facial injuries due to motor vehicle accidents. The use of seat belts has, however, also modified injury patterns in car occupants involved in accidents. This review traces the introduction of seat belt legislation and delineates the types of injury which have been attributed to seat belt wearing.

Expected marginal seat revenue (EMSR) is a well-known method for airline seat inventory control airlines. However, this method employs a static model to study the dynamic reservation process, and does not take into account the risk tolerance of policy makers. Expected marginal seat utility (EMSU) replaces revenue by utility, which addresses the real situation of seat inventory control. However,...

R.Kaeser Winterthur Engineering School Although much progress has been made in the field of passive car safety in the last years, there is still a strong need for safety improvements in rear-end impacts. While rear-end collisions seldom cause fatal injuries, lesions of the cervical spine are known to cause a high societal cost associated with their often long-term consequences. The critical bod...

The unit price seat reservation problem is investigated. The seat reservation problem is the problem of assigning seat numbers on-line to requests for reservations in a train traveling through k stations. We are considering the version where all tickets have the same price and where requests are treated fairly, i.e., a request which can be fulfilled must be granted. For fair deterministic algor...

OBJECTIVES This study presents an investigation of anti-whiplash features that can be implemented in a car seat to reduce whiplash injuries in the case of a rear impact. The main emphasis is on achieving a seat design with good energy absorption properties. METHODS A biofidelic 50th percentile male multi-body human model for rear impact is developed to evaluate the performance of car seat des...
