In times past in a country far away, passengers on intercity buses were all assigned seat numbers, and the buses were always full. There were many casual people, and there were a few people who were real sticklers for the rules. This is where our problem begins. Adam is the first person to enter an n seat intercity bus, and, since he is a casual person, he takes a seat at random. Subsequently, ...

Loading effects of aircraft seats in an electromagnetic reverberating environment are investigated. The effects are determined by comparing the reverberation chamber’s insertion losses with and without the seats. The average per-seat absorption cross-sections are derived for coach and first class seats, and the results are compared for several seat configurations. An example is given for how th...

Seat cushions for high-performance aircraft are typically selected for their ability to meet stringent specifications. One of the major criteria is the safety performance during an ejection. To address the design goals of cushion and material selection, a computational modeling method was developed that accounts for component and subsystem testing, component and subsystem modeling, validation c...

Injuries will inevitably occur when restraining loads are exerted on a car occupant by a seat belt during a crash. This study investigated the nature, frequency, and severity of such injuries to the chest and abdomen. Vehicle, occupant, and injury details were obtained from accidents occurring in the Midlands of England. The sample was chosen with emphasis on fatal and serious injuries while al...

BACKGROUND Motor vehicles crashes (MVCs) are the leading cause of injury related morbidity and mortality in developed countries. Recent evidence proves that properly used child seat belts can dramatically reduce the risk of severe and life-threatening injury from MVCs. There are rarities of thought and inspiration regarding the use of child seat belts in our society and region, therefore we lac...
