Alpinestars Carbon Bionic Neck Support (BNS) is a structure designed to work with a helmet to reduce the risk & severity of a catastrophic neck injury. Function The Bionic Neck Support functions by providing an alternative load path for the energy that compresses the neck. If the helmet is in contact with the BNS 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 & minimize the risk of collateral injury as the impact load is channelled away from the neck. When compared to soft neck roll devices the protection afforded is significantly better since soft devices deform on impact offering no protection against the damaging compressive forces. As with any riding equipment fit is critical to ensuring the most effective protection possible & riders should choose the equipment that is best suited to their body. No neck device should roll around over the shoulders. Key Features Carbon Composite frame to maximize frame stiffness & minimize weight. Two different EVA foam densities are used in the BNS SB: Firmer EVA in the shoulders & softer EVA on the chest & back for comfort. Pivot Key system
- A special magnesium key located at the rear allows convenient front opening of the device & allows for dismantling in an emergency. Fitting System
- Fine adjustment of the shoulder height allows a personalized fit particularly for individuals with shorter necks. Rear Stabilizer system
- In the event of large loads being channelled onto the rear stabilizer (the part that sits on the back) there are several bending & fracture points designed to relieve extreme loads that may be transmitted down the back. Collar Bone preservation 1
- All parts in contact with the body use an expanded foam compound to distribute the impact force over the widest area yet remain lightweight. Collar Bone preservation 2
- A continuous frame member runs over the shoulders. This means there are no weak points in a critical part of the frame & that there are no metal pins or screws sitting directly above the shoulders which could be dislodged into the shoulders or collarbone during an accident. Choice of Strap Systems
- The BNS is supplied with the X-Strap System which allows a small light strap worn over or under the jersey to secure the device to the rider. The larger A-Strap assembly provides a traditional chest strap for those who like to wear the protector tight against the body. Mounting points for accessories (Allows for integration of the BNS with other Alpinestars accessories.) For sizing information please visit www.alpinestars.com/sizechartbns.htm Note: While no product can guarantee protection from all motorcycle injuries due to the varied dynamics of accidents the BNS is designed to substantially reduce the likelihood of a career ending neck injury. The BNS as with other neck support systems may not prevent injuries in all cases.
