would you wear an inflatable bike helmet? airbag is six times better at absorbing impacts than foam
But there are concerns that while traditional bike helmets can put more risk to cyclists, they do not provide adequate protection against injuries.
Now, American researchers believe alternatives to hard-foam helmets borrowed from airbags in most modern cars can help save lives.
The video oa team at Stanford University is conducting crash tests on helmets to measure the level of protection they provide to standard foam helmets.
While traditional helmets can play a role in crashes and reduce skull fractures, cyclists may not be as safe as they think.
David Camarillo, a bioengineer at Stanford University, said Foam bike helmets can and have been shown to reduce the likelihood of skull fractures and other more severe brain injuries.
But I think a lot of people mistakenly think that the bike helmet is used to prevent concussion.
That\'s not true.
In the lab, the tests show that helmets with airbags can significantly reduce acceleration, resulting in more serious damage.
They claim that the inflatable helmet is 6 times more effective than the foam replacement.
The commercial airbag for cycling has been on the market for many years and consists of a collar worn around the neck that contains an inflatable device.
The algorithm in the collar detects when a cyclist falls and expands the airbag in less than a second in order to surround the head.
Swedish manufacturer Hövding is one of the companies that make airbag helmets for cyclists.
However, they are much more expensive than traditional bike helmets for around £ 219 ($279)each.
Once the airbag is deployed, it needs to be replaced, just like the traditional helmet after the collision.
Tests conducted by the company in 2014 showed that the devices were three times safer than conventional head protection devices.
Mehmet Kurt, one of Stanford\'s teams, explained that we had a drop test, which is a typical federal test to evaluate the bike helmet.
\"We found that airbag helmets with proper initial pressure can reduce head acceleration by 5 to 6 times compared to conventional bike helmets.
\"Using a fake head with an accelerometer to measure the force involved, the team dropped the head from multiple Heights to a solid platform-the equivalent of someone filling the handlebar and head.
The findings were published in the biomedical engineering Yearbook.
As our paper suggests, although the airbag helmet has the potential to reduce the level of acceleration you have experienced in a bike accident, Dr. Kurt said, this also shows that the initial pressure on your airbag helmet is critical to reducing these acceleration levels.
If the airbag is not fully inflated, the team claims that this may cause the head to hit the ground with greater force compared to the rider wearing a standard foam helmet.
They added that the airbag approach could prevent concussion-which is considered to be the result of rapid distortion of brain tissue during an impact, stretch neurons-paving the way for people who use this helmet around the world to protect cyclists.
If our research with others began to provide increasing evidence that this airbag approach might be more effective, Dr. camarillo added: \"In the United States, legitimate provision of a device to the public will face some major challenges. \".
