The device prevented the driver's head from hitting the edge of the cockpit or the steering wheel during an accident. Without the HANS device, the driver could suffer serious neck and skull injuries, including a potentially fatal basal skull fracture. We consider our development and testing work to be a significant contribution towards making auto racing even safer. The basic HANS concept was invented by Dr. Robert Hubbard, professor at the biomechanic constructions research laboratory at Michigan State University, and Jim Downing, a sportscar racing veteran and chassis builder, for use in sports car racing. HANS is a rigid, collar-shaped carbon fibre shell that is held onto the upper body by the seat belts and fastened to the helmet with appropriate tethers.
Drivers still have full movement of their heads while wearing the device.
Made from a composite material, the HANS weighs less than two pounds. It is particularly significant that this research has been carried out jointly with one of the world's major car manufacturers. This shows how motor sport is a research medium for the motor car industry not only for performance, but also for safety. Through testing with the West McLaren Mercedes Formula One team, further adjustments are currently being made to the HANS system to improve driver comfort. The FIA Safety Commission and DaimlerChrysler safety experts have recommended its introduction in Formula One for next season.
