Child anthropometry for improved vehicle occcupant safety.
A detailed understanding of the size, shape, and postures of children is required to design effective restraint systems for protecting children in motor vehicle crashes. Compiled and edited by experts in the fields of anthropometry, ergonomics, and child restraint, this book includes 14 important...
Effects of vehicle seat and belt geometry on belt fit for children with and without belt positioning booster seats.
A laboratory study was conducted to quantify the effects of belt-positioning boosters on lap and shoulder belt fit. Postures and belt fit were measured for forty-four boys and girls ages 5–12 in four highback boosters, one backless booster, and on a vehicle seat without a booster. Belt anchorage...
Child passenger restraints in relation to other second-row passengers : an analysis of the 2007-2009 National Survey of the Use of Booster Seats.
Objective: Child restraint systems (CRS) are increasingly being designed to accommodate larger children and to mitigate side impact injuries. Little is known about the impact of CRS on the safety of other vehicle passengers due to limitations of existing crash databases. This study provides the...
Measuring young drivers behaviors during complex driving situations
A laboratory study was conducted to quantify the effects of belt-positioning boosters on lap and shoulder belt fit. Postures and belt fit were measured for forty-four boys and girls ages 5–12 in four highback boosters, one backless booster, and on a vehicle seat without a booster. Belt anchorage...
Factors affecting tether use and misuse
This project investigated factors relating to tether use and misuse. Volunteer testing was performed with 37 subjects on 16 different vehicles using 2 forward-facing child restraints (Britax Marathon 70 or the Evenflo Triumph), with each subject performing 8 child restraint installations on a set...
Assessing the restraint performance of vehicle seats and belt geometry optimized for older children
In a previous study, a computational model of child occupants 6 to 10 years old (YO) was validated using data from a sled test series with the 6YO and 10YO Hybrid III ATDs. Simulations using this model were used to identify characteristics of a vehicle seat and belt geometry that would improve...
Kinematics of pediatric crash dummies seated on vehicle seats with realistic belt geometry
A series of sled tests was performed using vehicle seats and Hybrid-III 6-year-old (6YO) and 10YO anthropomorphic test devices (ATDs) to explore possibilities for improving occupant protection for children who are not using belt-positioning booster seats. Methods: Cushion length was varied from...
