The new HANS Sport II head and neck support device for racing drivers uses renewably sourced DuPont™ Zytel® RS polyamide to deliver needed impact resistance while significantly reducing weight. The device is credited for saving many lives and is required on circuits run by NASCAR, CART, Formula 1 and NHRA.

“Using Zytel® RS to injection mold this HANS device enabled us to continue to make the same protection enjoyed by champions in major series around the world available at a reasonable price,” said Gary Milgrom, vice president, HANS Performance Products, Atlanta, Ga.

Molded by HiPer Technology Inc., the new HANS Sport II is the lightest ever Sports Series HANS Device, weighing in at 30% lighter than the previous Sport model.

“Weight is absolutely critical in motor sports applications,” said Christopher Bovis, vice president of marketing, HiPer Technology, Inc., Lawrence, Kan. “We worked very closely with DuPont Performance Polymers as they developed a new grade of Zytel® RS that maintained strength and stiffness needed to surpass all national and international safety standards."

This grade of Zytel® RS is a toughened carbon-fiber/glass-fiber reinforced polyamide that is strong, impact resistant and chemical and moisture resistant. Zytel® RS products are made from non-food based renewable sources.

“With Zytel® RS, the physical properties and ease of production have allowed HiPer and HANS Performance Products to produce a smaller and lighter HANS Device with integrated features that make exiting a car in an emergency a faster process,” said Bovis.

The HANS Sport II device was invented by Robert Hubbard, Ph.D., a professor of biomechanical engineering at Michigan State University, with his brother-in-law, racer Jim Downing, in an effort to reduce the potential for serious and fatal injuries.
