There is no such thing as a correlation between the worth of a helmet and its safety degree, in response to a brand new examine from Imperial School London, printed on Thursday.
Researchers examined 30 of essentially the most widespread grownup helmets available on the market, all medium sized, primarily based on a mix of in-lab testing, knowledge from main retailers, and a survey of greater than a thousand cyclists after which ranked them primarily based on their threat degree.
Whereas all helmets bought within the UK, and examined within the Imperial examine, have to fulfill European security requirements, some provided much more safety than others, in response to the examine.
The most effective-performing helmet of the check – in response to the researchers and primarily based on their protocol – was the Specialised Tactic MIPS, which may be purchased for £50, whereas costlier lids just like the Kask Protone (£135) got here additional down their desk. The general threat rating was calculated as a mean of the linear and the rotational threat, which assumes they’ve equal significance and presence in real-world casualties.
The examine centered on security, and didn’t have in mind aerodynamics, breathability and weight, which additionally have an effect upon price.

The complete outcomes may be seen at www.hiperhelmets.org. Helmets have been given scores from 0-5 with the intention to enable prospects to know the outcomes, and likewise help producers in future helmet design. Plans are in movement so as to add youngsters’s helmets sooner or later.
The examine was printed in Annals of Biomedical Engineering on Thursday, and was funded by The Highway Security Belief, which has prolonged its funding for 3 years. Ruth Purdie, the chief govt of the belief, mentioned that the brand new ranking system was “extremely essential”.

The examine’s lead creator, Dr Claire Baker, from Imperial’s Dyson College of Design Engineering, mentioned: “Till now, there was restricted details about how properly cyclists can anticipate their helmet to guard them throughout head influence. It is because present security requirements are merely move/fail and solely check direct influence sustained throughout straight-on head influence.
“Nonetheless, proof from earlier research reveals that lasting mind injury happens in additional severe impacts or when the top undergoes speedy rotation throughout an influence.”
“All helmets bought in Europe should meet the EN1078 minimal security commonplace, however we needed to find out whether or not some provided higher security safety than others in reasonable collision exams,” Dr Baker continued.
Describing the protocol, she mentioned: “We developed a easy scoring system to charge helmets primarily based on the danger of head damage throughout a collision. The chance of damage took account of the probability of deep mind accidents from head rotation in addition to extra floor degree accidents and potential cranium fractures from direct influence. Our scoring ranges from zero for decrease safety to 5 for one of the best available on the market.
“Curiously, we discovered no correlation between worth and safety, with the highest-performing helmet being one of many inexpensive, retailing at round £50. Our new scores give customers goal, evidence-based knowledge to assist their shopping for selections.”
Senior creator Dr Mazdak Ghajari, from the identical college as Dr Baker, can also be a member of the working group accountable for one of many European requirements on helmet security.
“The science of mind biomechanics has superior tremendously and we now know far more about how greatest to guard the human head from severe damage and accidents with long-term results in a collision,” he mentioned.
“We’re sharing our findings with helmet producers and people accountable for setting testing requirements, in order that the trade can preserve tempo and develop merchandise that provide the absolute best safety.
“Due to funding from the Highway Security Belief, our analysis can now assist customers to make an knowledgeable alternative after they purchase a helmet. We imagine these scores will result in additional enhancements in helmet designs, offering higher safety towards a spread of head and mind accidents if a bicycle owner is concerned in a fall or collision.”
