HISTORY
• The device was designed in the early 1980s by Dr. Robert Hubbard, a professor of biomechanical engineering at Michigan State University. After talking to his brother-in-law, road-racer Jim Downing, after the death of one of their mutual friends, who was killed in IMSA testing accident at Mid-Ohio, when his Renault Le Car struck a sandbank leaving him dead on arrival with head injuries, it was decided that some sort of protection was required to help prevent injuries from sudden stops, especially during accidents. A major cause of death amongst drivers during races was through violent head movements, where the body remains in place because of the seat belts but the momentum keeps the head moving forwards, causing a Basilar skull fracture resulting in serious injury or immediate death.
DESCRIPTION
• Primarily made of carbon-fiber, the device is something of a U-shape, the back of the U set behind the back of the neck and the two arms laying flat along the top of the chest over the pectoral muscles; the device in general supported by the shoulders. It is attached only to the helmet—and not to the belts, driver's body, or seat -— by two anchors on either side, much like the Hutchens device but placed slightly back. The seat belts that cross the driver's upper-body are properly installed so that the belts go right over the HANS device, on the driver's shoulder, and buckle into the center of the driver's stomach. Therefore, the HANS device is secured with the bodyof the driver, not the seat.
• The purpose of the device is to stop the head from "whipping forward" in a crash, without otherwise restricting movement of the neck. In a crash, an unprotected body is decelerated by the seatbelt with the head maintaining velocity until it is decelerated by the neck. The HANS device maintains the relative position of the head to the body, with the device transferring energy to the much stronger chest, torso, shoulder, seatbelts and seat as the head is decelerated.
Introduced to Formula One racing in 2003, the Head and Neck Support (HANS) system consists of a carbon fibre shoulder collar which is secured under the driver’s 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 driver’s 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 driver’s head, while the collar absorbs and redistributes the forces generated by the head’s pendulum momentum - forces that would otherwise be absorbed by the driver’s 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.
• The original HANS device went on sale in 1990, but its large collar was unsuited to single-seater series with narrow, tight cockpits. However, after Mika Hakkinen's enormous accident in Adelaide in 1995 (in which he fractured his skull) the FIA instituted research to establish the best way of protecting Formula One drivers' heads in major impacts. Airbag and 'active' safety systems were briefly considered, before the focus shifted to development of a HANS system suitable for F1 racing
Did you know …that in tests HANS was shown to reduce typical head motion in an accident by 44 percent, the force applied to the neck by 86 percent and the acceleration applied to the head by 68 percent - bringing the figures for even large impacts under the 'injury threshold'?
• Another driver to benefit from the use of a HANS Device was 14-time NHRA Funny Car Champion, John Force. During a race against fellow racer Kenny Bernstein at the Texas Motorplex, Force's car broke in two after severe tire shake, sending the rear part, containing the cockpit into the wall at almost 300 mph, before coming to rest at the track's halfway point. Force received several injuries, including a fractured ankle, bilateral wrist fractures, several severed finger tips and a severe laceration to his right leg, but received no head injuries.
• In April 2008 in Texas Motor Speedway, Michael McDowell, a NASCAR Driver who was a rookie making his second career start in the Sprint Cup Series, got loose in Turn 1 during qualifying and spun head on to the wall and flipped eight times. After the crash McDowell got out of his #00 Aarons Toyota and walked away with no injuries.
