Investigation of Potential Design and Performance Criteria for Booster Seats Through Volunteer and Dynamic Testing
The purpose of this research was to explore candidate booster performance metrics that have the potential to identify less effective booster systems. A combination of volunteer testing of belt fit and posture along with dynamic sled tests of booster seats was employed to achieve the project goals. Posture and belt fit were measured in 24 child volunteers 4 to 12 years old.
Children were measured in three vehicles and three laboratory seating conditions selected to provide cushion lengths and belt geometries representing the range found in late model vehicle rear seats. Six different booster seats, as well as the no-booster condition, were evaluated.
