By restraining the head to move with the torso in a crash, excessive head motions, neck forces, and injuries are dramatically reduced. Many racers credit the HANS with helping them to continue racing and for saving their lives. The HANS Device has been built to industry standards, including those of the SFI and the FIA and is approved by the FIA, NASCAR, and the NHRA among other sanctioning groups worldwide.

The new Vision Advantage PLUS sliding tether system from HANS has been shortlisted for the 2008 Safety Innovation of the Year Award. The sliding tether system allows a full range of head motion under normal race conditions and provides the same impact performance. The Vision Advantage PLUS sliding tether system permits improvements in left and right visibility by allowing easy but controlled rotation of a racer's helmet. The proven results are tethers that allow a much greater field of vision.

Leatt Brace
The Leatt-Brace is an injection molded, glass reinforced nylon or carbon-fiber and Kevlar neck-brace system designed by medical professionals and motorcycle enthusiasts to help prevent:

Hyperflexion: extreme forward head movement.

Hyperextension: extreme rearward head movement.

Lateral Hyperflexion: extreme sideways head movement.

Axial loading: compression of the spinal column due to the effect of force on the helmet.

Posterior hypertranslation: rearward movement of the head on the neck.

The Leatt-Brace allows normal driver mobility and the ability to look sideways. Delphi (70g) and other Sled Tests (SFI 38.1 accredited), High-G Drop Testing, Destruction Testing, and Accident Simulation Software were used along with other engineering design tools to achieve optimum reduction in neck forces without compromising other body dynamics.

The design rationale behind the Leatt-Brace is to bring the head to a controlled stop. This is achieved by slowing the movement of the head until it reaches a controlled stop against the padded, rigid anatomical brace perimeter. This slowed movement also reduces levels of neck tension. In addition, the Leatt-Brace doesn't restrict the driver's mobility, something that seems to be more of a concern amongst drivers than many initially thought.

The Leatt-Brace doesn't require any equipment modification and is compatible with most helmet, safety harness, and seat combinations. It doesn't rely on the safety harness only to be effective. In fact, it keeps the safety harness away from the soft tissue neck structures and at the same time allows the belts to fit more comfortably. The brace is also compatible with open faced helmets and therefore used in Off Road and Rally categories.

Conclusion
Ed Coughenhour owner of PitStopUSA.com reports, "Many racers still are not wearing any head and neck restraint. This is particularly prevalent in the open-wheel Sprint Car and Midget ranks. It's crazy that these sanctioning bodies don't require mandatory head-and-neck restraint use."

No matter if you're racing Street Stocks on dirt, Legends cars, Pro-4 Modifieds, on up to Super Late Models, or any other short-track type of car, you need to protect yourself from a high g-force frontal impact. These head-and-neck restraint systems are specifically designed to help you survive those impacts. It may seem like a rare occurrence to many, but it only takes one crash to hurt you. Do the right thing by completing your safety package with a head-and-neck restraint system.
