Students from IIT-Roorkee have developed a helmet that can be worn like a collar around the neck and inflates like an airbag before impact during an accident.
Made of Kevlar, a synthetic fibre used to make bullet-proof jackets, the inflatable helmet offers better protection than traditional ones, said, Rajvardhan Singh, one of the three B Tech students who developed the prototype.
“The traditional helmets protect only against skull fractures and not against internal brain bleeding and damage caused by the rapid de-acceleration during an accident. Our impact assessment showed inflatable helmets can reduce the peak crash acceleration up to four times, meaning it absorbs the kinetic energy generated during the crash and then releases it slowly, lowering damage from impact,” Singh said.
The helmet works like an airbag that opens up in less than 100 milliseconds of impact.
