The Debate Between Stiff and Yielding Seats

In 1967, Derwyn M. Severy and his colleagues published several SAE papers that demonstrated improvements in occupant retention with rigid (stiff) seats, sparking a debate that lasted for nearly four decades. The Debate Between Stiff and Yielding Seats presents an interesting and informative history of this debate, delving into the many questions and answers that continue to surround each of these seat types.

The Debate Between Stiff and Yielding Seats begins with new material from editor David C. Viano, explaining the key factors that allowed the debate to be resolved. The publication then analyzes the effects of stiff and yielding seats on various crash scenarios, followed by an exploration of high retention seats. Patent information, new studies, and historical information are also included, making this comprehensive collection an essential resource for any safety professional's library.
