Design and Evaluation of an Affordable Seatbelt Retrofit for Motor Coach Occupant Safety

2017-01-10
2017-26-0018
Prevention of passenger ejection from motor coach seats in the case of rollover and frontal crashes is critical for minimizing fatalities and injuries. This paper proposes a novel concept of affordably retrofitting 3-point seatbelts to protect passengers during these significant crash scenarios. Currently, the available options involve replacement of either the entire fleet, which takes time to avoid extremely high costs, or all seats with new seats that have seatbelts which is still expensive. Alternatively, this paper presents the development of an innovative product that can be installed in seat belt-ready bus structures at a fraction of the cost. The efficacy of the design is studied using finite element analysis (FEA) to meet Federal Motor Vehicle Safety Standards (FMVSS) 210 standards for conditions involved in frontal and side impacts.

Real-time Crash Detection and Its Application in Incident Reporting and Accident Reconstruction

Characterizing or reconstructing incidents ranging from light to heavy crashes is one of the enablers for mobility solutions for fleet management, car-sharing, ride-hailing, insurance etc. While crashes involving airbag deployment are noticeable, light crashes without airbag deployment can be hidden and most drivers do not report these incidents. In this paper, we are using vehicle responses together with a dynamics model to trace back if abnormal forces have been applied to a vehicle so as to detect light crashes. The crash location around the perimeter of the vehicle, the direction of the crash force, and the severity of the crashes are all determined in real-time based on on-board sensor measurements which has further application in accident reconstruction. All of this information will be integrated to a feature called “Incident Report”, which enable reporting of minor accidents to the relevant entities such as insurance agencies, fleet managements, etc.

Advances in Side Airbag Systems

2005-01-15
Thanks to years of research and development by vehicle manufacturers, suppliers, legislation, and the entire safety community, the side airbag has become a critical safety device to reduce injury and save lives. This new collection of technical research highlights the progression of these essential safety features, providing a complete and thorough perspective through the analysis of both early patents and recent side airbag system developments. Advances in Side Airbag Systems begins with an introduction by editor Donald E. Struble, chronicling the progress made since the mid-1980s in offering improved side impact protection to the motoring public. Authored by leading experts in their respective fields, this book features a comprehensive collection of 26 landmark technical papers. Its scope includes not only thorax airbags, but other inflatable devices designed for side impacts and rollovers.
