Alpinestars仿生颈部支撑（BNS）是一种旨在与头盔配合的结构，以减少颈部灾难性损伤（即瘫痪性损伤）的风险和严重程度。新的BNS SB模型成分是由强化聚氨酯与可变密度EVA泡沫混合而成。
仿生颈部支撑。
功能
- 仿生颈部支撑的功能是为压迫颈部的能量提供一个替代的负载路径。如果头盔在撞击的瞬间与BNS接触，通过颈部的整体负载可以减少，这可以防止骨折的发生。
- BNS还有助于减少与极端的头部运动相关的肌肉损伤的机会。
- 虽然不可能消除任何形式的伤害风险，但BNS的设计有助于防止最严重的伤害，并将附带伤害的风险降至最低，因为冲击载荷被引导到远离颈部的地方。
- 与软质的颈部滚动装置相比，所提供的保护要好得多，因为软质装置在撞击时变形，对破坏性的压缩力没有保护作用。
- 与任何骑行装备一样，适合是确保最有效保护的关键，骑手应该选择最适合自己身体的装备。颈部设备不应该在肩膀上滚动。
主要特点
- 主体结构是由强化的聚氨酯复合材料混合而成，在不同的温度下进行了广泛的冲击测试，以确保颈环保持完整。
- BNS SB使用两种不同密度的EVA泡沫：肩部使用较硬的EVA，胸部和背部使用较软的EVA，以保证舒适性。
- 枢轴钥匙系统--位于后部的特殊镁质钥匙可以方便地在前面打开设备，并可以在紧急情况下进行拆卸。
- 合身系统 - 肩部高度的微调可以实现个性化的合身，特别是对脖子较短的人。
- 后稳定器系统 - 在大的负荷被引导到后稳定器（位于背部的部分）的情况下，有几个弯曲和断裂点，旨在缓解可能被传递到背部的极端负荷。
- 领骨保护1 - 所有与身体接触的部分都使用膨胀的泡沫化合物，将冲击力分布在最广泛的区域，但仍保持轻质。
- 领骨保护2--一个连续的框架部件贯穿肩部。这意味着在框架的关键部分没有薄弱点，也没有直接位于肩膀上方的金属销或螺丝，在事故中可能会移位到肩膀或锁骨。
- 带子系统的选择 - BNS提供X-带子系统，它允许一个小的、轻的带子穿在球衣上或穿在球衣下，将设备固定在骑手身上。较大的A-Strap组件（可作为单独的附件）为那些喜欢将保护器紧贴身体的人提供了传统的胸带。
- 配件的安装点--允许BNS与其他Alpinestars配件整合。
- 有XS尺寸。
注意。 由于事故的动态变化，没有任何产品能够保证对所有摩托车伤害的保护，但BNS的设计是为了大大减少职业生涯结束时颈部受伤的可能性。与其他颈部支撑系统一样，BNS不可能在所有情况下都能防止受伤。

Alpinestars Bionic Neck Support (BNS) is a structure designed to work with a helmet to reduce the risk and severity of a catastrophic neck injury (i.e. paralyzing injury). The new BNS SB model composition is a blend of strengthened polyurethane with variable density EVA foam.
BIONIC NECK SUPPORT:
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 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 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 and riders should choose the equipment that is best suited to their body. No neck device should roll around over the shoulders.
Key Features
- Mainframe construction is a blend of reinforced Polyurethane composite material extensively impact tested at varying temperatures to ensure the neck ring stays intact.
- Two different EVA foam densities are used in the BNS SB: Firmer EVA in the shoulders and softer EVA on the chest and back for comfort.
- Pivot Key system - A special magnesium key located at the rear allows convenient front opening of the device and 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 channeled onto the rear stabilizer (the part that sits on the back) there are several bending and 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 and 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 (available as a separate accessory) provides a traditional chest strap for those who like to wear the protector tight against the body.
- Mounting points for accessories – Allow for integration of the BNS with other Alpinestars accessories.
- Available in XS sizes.
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.
