Restraint Systems

Dr. Renfroe has studied the mechanical properties of restraint systems, such as seatbelt buckles and retractor systems.  Dr. Renfroe and Dr. Thorbole, Biomechanist & Occupant Motion Specialist, have an understanding of the interaction of the seat back and airbags in occupant motion during vehicle collisions. Most significantly they understand the effects of airbag deployment timing and seat back deflection during a collision on occupant injury potential.
