Dr. Srini Sundararajan: passive safety expert led development of Ford’s new inflatable seat belt

Automotive safety innovations don't happen overnight. Just ask Dr. Srini Sundararajan, Ford Motor Company's technical leader on the development of its new inflatable seat belt system – a project that has been in the works for approximately 10 years.

"Combining the functionality of a safety belt and some of the benefits of an air bag into one occupant protection system was easier said than done," says Sundararajan. "There were many challenges along the way – such as determining the need to inflate through a special buckle and the need to use a special retracting system that could handle a thicker belt. There was much trial and error before we hit upon the right solutions." The 21-year Ford veteran has applied his expertise of vehicle occupant biomechanics and advanced restraint development to a number of other safety projects at Ford as well. He led the development and evaluation of the industry's first comprehensive automatic collision notification system by completing a study of 500 police vehicles in Texas to establish its operational parameters in real-world crash scenerios. Sundararajan also guided Ford's development of deployable door trim systems designed to improve side-impact protection. The systems exceeded stringent federal expectations for crash protection, and earned Sundararajan a Henry Ford Technology Award for invention and implementation. Sundararajan also led innovative biomechanics research on the human cervical spine movement during rear end collisions, which influenced seatback and head restraint designs at Ford.He also led research and development of automatic adjustable head restraints to enhance occupant protection in low-speed rear-end impacts, and a leading orthopedic manufacturer used his research methodology to obtain FDA approval for cervical implants. In addition to helping protect vehicle occupants, Sundararajan has helped protect pedestrians with his work as well. He led development of an active hood system for pedestrian head protection, and directed Ford's North American vehicle assessment of proposed global regulations for pedestrian safety. Sundararajan's interest in safety began in the aerospace industry where he worked on structural design for safety of helicopter pilots and passengers. He made the transition to automotive, and moved to Michigan from Texas after earning his master's degree at the University of Texas in Arlington. "A friend of mine was working in Ford and told me the company was looking for people with crash safety expertise, and I asked 'does helicopter crash safety count?' and he said sure," Sundararajan said. "In both aerospace and automotive, my passion has always been safety." * Ford Motor Company's Passive Safety Research team relies on the expertise of Technical Leader Dr. Srini Sundararajan, who led the development of Ford's new inflatable safety belt * Sundararajan also has guided Ford's development of deployable door trim systems designed to improve side-impact protection, and led innovative biomechanics research on the human cervical spine movement during rear-end collisions
