Airbag helmets may reduce impact of
a crash by six fold compared to traditional bike helmets, drop tests from a
height of two metres have shown. Foam helmets can and have been proven to
reduce the likelihood of skull fracture and severe brain injury. But, many falsely
believe that a bike helmet is there to protect against a concussion. Researchers
tested a new type of helmet that comes in a soft pocket worn around the neck. It
pops up, like an air bag, around a person’s head when it senses a potential
collision. Researcher said that the large size of the airbag helmet, compared
to foam bike helmets, was the likely source of its success. Being larger, it
can also be softer, allowing for a more cushioned fall. However, this cushioning
also has a potential downside. In the testing, the airbag helmet was
pre-inflated and the researchers maximized the pressure of the air inside the
helmet before each drop in order to get these results.
