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...

A growing issue in the area of vehicular ride comfort is that of child safety seats. Postural, thermal and vibrational comfort considerations are finding their way into child seat design. This paper makes some observations regarding the current state of child safety seat design, then goes on to present the results of vibration tests performed over two road surfaces using two child seats and two...

The risk of death of unbelted rear-seat occupants is obviously increased in car crashes. However, there is little epidemiological evidence that unbelted rear-seat occupants will also increase the risk of death of front-seat passengers. We compared risk of death and severe injury of front-seat occupants in car crashes with belted or unbelted rear-seat passengers. The risk of death of belted fron...

Roadway incidents involving motorized vehicles accounted for 24% of fatal occupational injuries in the United States during 2013 and were the leading cause of fatal injuries among workers.* In 2013, workers' compensation costs for serious, nonfatal injuries among work-related roadway incidents involving motorized land vehicles were estimated at $2.96 billion.(†) Seat belt use is a proven method...

OBJECTIVE To describe several aspects of booster seat use and misuse in a sample of children attending child safety seat clinics. METHODS Booster seat practices were assessed at 76 child safety seat clinics held between April 1997 and January 1999 in Pennsylvania and southern New Jersey. At each assessment, a child passenger safety team evaluated the booster seat and identified modes of misus...

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; ...

This study finds that the break-even point for child safety seat misuse reduction programs and vehicle and seat design improvements is dollars 121 a year per child seat in use, annual misuse reduction program cost is dollars 6, and Lower Anchors and Tethers for Children (LATCH) cost dollars 13 annually per seat in use (in 2004 dollars). To estimate societal injury cost savings we compared tow-a...

The purpose of this study is emphasized on searching for the ergonomic child safety seating design to reduce the neck injuries during forward car collision. The new designed prototype of ergonomic safety seat, featuring with two cushions under the seat, buffering device in the back-rest support and lowery placing the child restrain belt through the rear side of the seat, is suitable for the use...

To design and develop a comfortable driver’s seat, cheaper in cost and adds value to the customer is an important issue in an automotive industry. It is tough to design such a driver car seat. However, taking account all these things many researchers have put effort to design and developed a driver car seat considering various aspects (e.g. Biomechanical, materials, vibration absorption, safety...
