The BNS functions by providing an alternative load path for the energy that compresses the neck. If the helmet is in contact with the Bionic Neck Support at the moment of impact the overall load passing through the neck can be reduced, which may prevent a fracture from occurring. The BNS also helps reduce the chance of muscular injuries associated with extremes of head movement. While it is not possible to eliminate the risk of any form of injury, the BNS is designed to help prevent the most serious damage and minimize the risk of collateral injury as the impact load is channeled away from the neck. When compared to soft ‘neck roll’ devices the protection afforded is significantly better because being soft, these devices simply deform, offering no protection against the damaging compressive forces. A special magnesium key located at the rear allows the convenient front opening of the device while also allowing it to be dismantled in an emergency. Fitting System: Fine adjustment of the shoulder height allows a more personalised fit., particularly for individuals who have a shorter than normal neck. Rear Stabiliser Failure system: In the event of large loads being channeled onto the rear stabiliser (the part that sits on the back) there are a number of deliberate bending and fracture points.
