    The HANS III represents the third and latest generation of injection molded HANS devices and features a contemporary approach to reducing weight. Using an all new design combined with the latest technological advances in polymer construction, the HANS III features a hollow collar, which aids in maximizing weight savings, without sacrificing any strength. Specially engineered reinforcements ensure an exceptionally strong structure that provides the same level of safety as every HANS device. The reduced mass guarantees the lightest and most comfortable injection molded HANS ever. SFI tag is loacted on the strap on the Hans III device.

      NOTE: This is a high-speed video replayed in slow motion. The elapsed times on the video are marking points for the slow motion replay. Five seconds in this video equate to 100 milliseconds in real time. (An eye blink lasts 400 milliseconds.)

      1-Second Mark: The torso is held in the seat by properly tightened belts. Helmets are properly fastened.

      2-Second Mark: The torso begins to move forward due to belt elongation and compression of the dummy.

      3-Second Mark:
    • (Top) The unrestrained head begins to pitch forward. The elongation of the belts allows the dummy's torso to slide further forward in the seat.
    • (Bottom) The friction rubber on the legs of the HANS has engaged the belts to straighten and load the tethers, enabling the helmet and head to move with the torso. The HANS keeps the head and helmet in normal relationship to the torso despite the elongation of the belts.

      4-Second Mark:
    • (Top) The neck loading increases as the unrestrained head reaches maximum excursion, increasing tension in the neck beyond the threshold for serious or fatal injury.
    • (Bottom) The HANS continues to be held in place by the friction rubber on the legs during the forward movement of the torso. The tethers straighten fully and remain substantially horizontal, keeping the head in normal relationship to the torso.

      5-Second Mark:
    • (Top) Instrumentation in dummy confirms the neck tension threshold for a serious or fatal injury - 4,000 Newtons - has been crossed.
    • (Bottom) The HANS restrains the head and instrumentation in dummy confirms neck tension is kept far below the threshold for serious or fatal injury.

    WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.


    WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
