HANS Device Seminar & Paper Presentation
Only recently has the racing industry acknowledged that the number one cause of racing-related fatalities is basilar skull fractures from excessive head motions and neck loading. Racing legend Dale Earnhardt‟s death proved to the racing world and the general public that what appears to be a low impact crash can be fatal. Under development and extensively tested for over a decade, there is a device that can reduce the risk of serious injury or even death to the driver in such a crash. It is the Head And Neck Support (HANS) device.

Abstract : Introduced to Formula One racing in 2003, the Head and Neck Support (HANS) system consists of a carbon fibreshoulder collar which is secured under the driverís safety belts and connected to his helmet by two elastic straps.
In the event of an accident, HANS is intended to prevent a stretching of the vertebrae and to prevent the driverís head from hitting the steering wheel.
Invented in the mid 1980s by Dr Bob Hubbard, a biomechanical engineering professor at Michigan State University in the USA, the passive HANS system works on a simple principle.
In the event of an impact, the helmet straps control the movement of the driverís head, while the collar absorbs and redistributes the forces generated by the headís pendulum momentum -forces that would otherwise be absorbed by the driverís skull and neck muscles, causing injuries ranging from whiplash to neck or skull fractures.
The helmet loading is also transferred from the base of the skull to the forehead, which is far better suited to taking the force.
