VENTETE - Novel collapsible cycle helmet with multi-density structural system, aiming to prevent traumatic brain injury and increase portability

空气质量、碳排放、健康、福祉和道路拥堵是英国社会和积极旅行面临的严重问题，步行和骑自行车是一个关键的DfT战略，以改善他们所有人。法定的DfT自行车和步行投资战略在两年内承诺了212亿英镑的基础设施和积极的旅游项目，目标是到2025年将短途自行车增加一倍。虽然骑自行车已被证明对健康有益，但骑自行车的人是最脆弱的道路使用者，2020年英国的数据显示，141人在道路上死亡，16，294人严重受伤，每十亿英里的死亡率和受伤率分别为28和3240，而汽车为3和307。瑞典的数据显示，头部和颅骨创伤占所有严重自行车损伤的26%，其中严重损伤率为42%。在帝国的工作表明，目前的头盔测试标准是有限的，因为他们只考虑线性影响，而不是旋转影响显示有助于创伤性脑损伤（TBI）。英国头盔使用率通常只有20%。不戴头盔的实际原因通常包括旅行之间的运输和储存，特别是在通勤时，不适，太热或太冷，不舒服或太重。显然需要一种在使用之间可以紧凑地储存的自行车安全头盔。我们的解决方案是VENTETE，这是一款自行车头盔，具有轻质充气结构系统，放气时仅占原始体积的1/10，与传统头盔相比，可提供上级冷却。BSI测试数据表明，VENTETE超过了当前标准，是同类最佳的线性冲击。在帝国理工学院的工作表明，现有的VENTETE概念在旋转冲击载荷下也表现出色。VENTETE、Adreco和帝国理工学院之间的这个合作项目的目标是建立在VENTETE概念的基础上，开发一种在旋转冲击试验中表现出色的一流设计。它将达到或超过国际标准化组织正在讨论的预计在1-2年内引入的额外标准。

Air quality, carbon emissions, health, wellbeing, and road congestion are serious issues facing British society and active travel i.e., walking and cycling is a key DfT strategy to improve them all. The statutory DfT Cycling and Walking Investment Strategy has £21.2bn over 2 years pledged for infrastructure and active travel projects with the ambition to double cycling for short journeys by 2025\. Although cycling has proven health benefits, cyclists are the most vulnerable of road users and in 2020 UK data shows 141 were killed and 16,294 seriously injured on the roads with fatality and injury rates per billion miles of 28 and 3240 respectively compared to 3 and 307 for cars. Swedish data shows that head and skull trauma account for 26% of all serious cycling injuries with a 42% rate of severe impairment. Work at Imperial shows that current helmet test standards are limited as they only consider linear impacts and not rotational impacts shown to contribute towards traumatic brain injuries (TBI).UK Helmet usage rates are typically only 20%. Practical reasons commonly cited for not wearing helmets include carriage and storage between journeys particularly when commuting, discomfort i.e., too hot, or cold, uncomfortable, or heavy. There is a clear need for a cycling safety helmet that can be stored compactly between uses. Our solution is VENTETE, a cycle helmet with a lightweight inflatable structural system that when deflated occupies 1/10 of its original volume and provides superior cooling compared to conventional helmets. BSI test data shows that VENTETE exceeds current standards and is best-in-class for linear impacts. Work at Imperial shows the existing VENTETE concept also performs highly under rotational impact loads.The objective of this collaborative project between VENTETE, Adreco and Imperial College is to build upon the VENTETE concept and develop a class leading design that will perform exceptionally in rotational impact tests. It will meet or exceed the anticipated additional standard under discussion by ISO for introduction in 1-2 years' time.
