For many centuries people have exploited the characteristics of the wool fibre. Most know the value of woollen clothing for keeping warm and that it retains this feature even when wet. In the home woollen blankets, carpets and materials all make life more comfortable. Sheepskin rugs are widely used on beds for long term patients to help prevent bed sores, and sheep skin car seat covers are very...

17 Zimmern RL, Campbell FW, Wilkinson IMS. Subtle disturbances of vision after optic neuritis elicited by studying contrast sensitivity. Effect of seat belt legislation on the incidence of sternal fractures seen in the accident department In the United Kingdom legislation on the compulsory wearing of seat belts was introduced on 1 February 1983. Subsequently the number of front seat occupants o...

INTRODUCTION The leading cause of injury and death among children in the United States is motor vehicle crashes. Even though restraint laws are in place and public awareness campaigns and educational interventions have increased, many children are still improperly restrained or not restrained at all. When correctly used, child restraints significantly reduce risk of injury or death. METHODS T...

In the literature value of driver’s head acceleration has been widely used as an objective function for modification suspension and/or seat characteristics in order to optimize ride comfort a vehicle. For these optimization procedures various lumped parameter Vehicle–Seat–Human models are proposed. present paper Quarter Car model is integrated with three Seat–Human different levels detail. The ...

This work describes the development and the application of a computer-based vehicle simulator. Such real-time simulation software is currently used in our Department as a tool for optimizing the design of a racing car, namely a single-seat vehicle for the SAE-ATA formula. Being based on our custom multibody library Chrono::Engine, the vehicle simulator exploits a recent formulation founded on v...

All hospitals should set policies that require the discharge of every newborn in a car safety seat that is appropriate for the infant's maturity and medical condition. Discharge policies for newborns should include a parent education component, regular review of educational materials, and periodic in-service education for responsible staff. Appropriate child restraint systems should become a be...

The National Institute for Occupational Safety and Health (NIOSH) researchers have investigated seat design issues for the occupants and operators of underground mine transport vehicles relative to wholebody vibration (WBV) and mechanical shock. Considering the ergonomic and engineering improvements made to underground mine shuttle car seats, this study has focused on reducing injury risk by im...

Passive mechanical systems have been used in automotive seat design to reduce whiplash injuries, but these designs can only be optimized for a small range of occupant mass and impact severity. The overall goal of this work is to develop an actively controlled car seat that can reduce injurious kinematics during a rear impact for a large range of occupant mass and impact severity. In this study,...

A new car seat design, which allows the back part of the seat (BPS) to lower down while a protruded cushion supports the lumbar spine, was quantitatively tested to determine its effectiveness and potentials in reducing whole-body vibration (WBV) and musculoskeletal disorders in automobile drivers. Nine subjects were tested to drive with the seat in: 1) the conventional seating arrangement (Norm...

In the development of foam seats, there are many design variables and design requirements to be taken into account. In this context, numerical simulation can be a valuable tool to facilitate this process and shorten its duration by minimizing the number of test specimens built and the number of real tests made. In general, the aim is to predict the response of a seat under certain conditions an...
