A committed research effort in understanding and improving child occupant protection in motor vehicles has been ongoing at NHTSA for many years. A renewed emphasis on child safety is underway as data show that motor vehicle crashes are the primary cause of death for children 4 and older. Currently, NHTSA has been conducting research on the protection of children in side impact crashes. Much of that research has focussed on the protection offered by child restraint systems (CRS). Additional research efforts are underway investigating the injuries resulting from rear interior components and surfaces to determine whether there is a need to increase the protection of rear-seat occupants.

Since children 12-years-old and younger represent more than half of the rear seat occupant population, NHTSA has also begun conducting research on protecting large children in the rear seat that use booster seats and seat belts. NHTSA is looking more closely at rear seat geometries, seat belt fit and other aspects related to the rear seat environment as applicable to older children.

Preliminary Drawings of an Upgraded Standard Seat Assembly (Autodesk Inventor, Size 24.5 MB - zipped) March 2015

NHTSA has been working towards upgrading the Federal Motor Vehicle Safety Standard No. 213, “Child restraint systems,” standard seat assembly to better represent a vehicle’s rear seat. Download the preliminary technical drawings of the upgraded standard seat assembly to evaluate child restraint systems in a frontal crash. Drawings are subject to change.
