IIT-Roorkee students have developed a helmet that can significantly help in reducing the number of deaths due to road mishaps in India. The students who worked on this unique project say the inflatable helmet, which is more effective than the conventional ones used by Indians, can reduce the chances of deep head injuries to a great extent. This helmet works like an airbag, which can provide the rider with a soft cushioning in times of collision.
The inflatable airbag helmet was developed by three final year mechanical engineering students at IIT Roorkee - Rajvardhan Singh, Sarang Nagwanshi and Mohit Siddha. The idea has been inspired from inflatable space structures which are not too expensive and are used for many space applications such as an inflatable space antenna
Regular helmets do not quite distribute pressure in case of an impact and also do not reduce peak acceleration. According to the tests conducted the IIT-Roorkee team, the inflatable airbag helmet reduced the force on the crash test dummy by up to four times on impact as compared to a conventional helmet. Also, the airbag helmet is able to reduce the peak acceleration as well.
The helmet is made up of Kevlar (same material used to make bullet-proof vests) and it houses sensors for lean angle, velocity, acceleration and so on. The moment, the collar detects an impact; it inflates into an airbag and forms a cushioning layer around the head so as to protect from major injuries. The airbag that surrounds the head helps to lessen the impact and peak acceleration which is what harms the head the most.. Once the proper production model of the helmet is ready, it could be priced somewhere around ₹ 2,000.
India reports the highest number of road mishaps as well as deaths dues to road accidents every year. One in every 10 people who die due to road accidents is an Indian. In 2017 alone, over 1.46 lakh people died in road accidents in India, which on an average comes around 400 people every day. Out of all roads mishaps, around 69 per cent involve two-wheelers. The use of a helmet is mandatory while driving a two-wheeler but many people use inferior quality helmets making them vulnerable to road-related mishaps.
