Effects of Head Restraint Interference on CRS Performance in Frontal and Side Impacts

Principal Investigator: John H. Bolte IV, PhD, The Ohio State University

Forward-facing child restraint systems (CRS) and high-back boosters are often tall enough to contact the vehicle seat head restraint when installed, but guidelines vary on whether or not head restraint interference is acceptable during CRS use. This project aims to study the effects of head restraint interference on dynamic child restraint system (CRS) performance by conducting sled tests simulating frontal and far-side impacts.

This project is currently underway. Further information will be added in late 2023 following project completion.
