Quantifying CRS Fit in the Vehicle Seat Environment: Dimensional Comparison Approach

Co-Principal Investigators: Amanda Agnew, PhD, The Ohio State University & Julie Bing, MS, The Ohio State University

The research goals of this study are to quantitatively define good fit of a child restraint system to a vehicle, to develop a correlation matrix to characterize good fit between various child restraint systems and vehicle seats; and to quantify any changes to child restraint system characteristics that influence good fit over time.

Kinematics of Rear Seat Child Occupants in Small Overlap Crashes

Principal Investigator: Kristy Arbogast, PhD, The Children’s Hospital of Philadelphia

The long-term goal of this line of research is to gain insight into injury causation for common injuries seen by restrained occupants in the rear seat. The project objective is to quantify the kinematics of rear seat adolescent occupants in small overlap crashes and to explore the combination of crash dynamics and initial occupant position that leads to movement of head towards the lateral structures of the vehicle.

Quantifying Children’s Posture in the Rear Seat: A Naturalistic Study (Multiple Year Project)

Principal Investigator: Kristy Arbogast, PhD, The Children’s Hospital of Philadelphia

The goal of the research is to develop data analysis strategies to identify postural triggers in the video data such that an analysis could be directed to a specific epoch in the video stream where the child is sub-optimally positioned; the primary analytical objective is to quantify how often and to what degree the child occupant is in a non-ideal position.

Injury Risk and Causation Scenarios of Children Involved in Rollover Crashes

Principal Investigator: Aditya Belwadi, PhD, The Children’s Hospital of Philadelphia

The broad long-term goals of this research project are to gain insight into causation of common injuries sustained by children in rollover crashes; and to provide vehicle and restraint system manufacturers with data needed to develop rollover injury-mitigation systems for children.

Analysis of Child Comfort in Forward-facing versus Rear-facing Child Restraint Systems

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

The long-term research goal of this project is to identify comfort level of larger, older children in rear-facing child restraints in order to support AAP and NHTSA guidelines. The specific aims of this study are: to identify variables for analyzing child seating position comfort (including parental perception); to analyze comfort and posture of young children (2-3 years old) in forward-facing and rear-facing child restraints; and to conduct a pilot study for real-world on-road driving.

Serious Teen Crashes: Identification of the Most Common Scenarios and Factors

Co-Principal Investigators: Allison Curry, PhD, MPH, The Children’s Hospital of Philadelphia & Catherine McDonald, PhD, RN, The University of Pennsylvania

The long-term research goal of the project is to continue to build scientific foundation for interventions and evaluations that reduce teen driver crash and fatality risk by gaining a more comprehensive understanding of teen crashes, and exploring similarities and differences of teen vs. adult crash scenarios.

Quantifying CRS Fit in the Vehicle Seat Environment – Digitization Approach (Multiple Year Project)

Principal Investigator: Aditya Belwadi, PhD, The Children's Hospital of Philadelphia

Automotive interior design optimization must balance the design of the vehicle seat and occupant space for safety, comfort and aesthetics with the accommodation of add-on restraint products such as child restraint systems (CRS). Important to this balance is understanding the breadth of CRS dimensions, especially as CRS design is constantly changing. Quantifying CRS Fit in the Vehicle Seat Environment – Digitization Approach (Year 2)The long-term objective is to gain insight into the geometric dimensions of commercially available CRSs and develop a virtual surrogate capable of being used in the design cycle of an automobile for virtual fitment and packaging.

Dynamic Comparison of Pediatric and the Small Female ATDs to Size-matched Pediatric Volunteers (Multiple Year Project)

Principal Investigator: Tom Seacrist, MBE, The Children’s Hospital of Philadelphia

The goal of this research is to quantify the dynamic differences between pediatric and 5th percentile female ATDs and matched pediatric volunteers in low-speed lateral and oblique crashes and apply that knowledge towards improved ATD biofidelity requirements.

Child Restraint System Misuse Nationally and in Full-vehicle Crash Tests (Multiple Year Project)

Principal Investigator: Mark R. Zonfrillo, MD, MSCE, The Children’s Hospital of Philadelphia

The goals of this study are to elucidate and reduce child restraint system (CRS) misuse through field observation of consumer practices, experimental studies, and dissemination of findings. The study will build on methods and data from previous projects to analyze patterns of child seat use and misuse, further characterize behavior in modern child restraint systems, and overcome limitations from previous studies; as well as elucidate the performance of properly used and misused CRS in full-scale vehicle crashes, adding valuable data to previously published studies using sled tests.
