AN IMPROVED MOTORCYCLE HELMET DESIGN FOR TROPICAL CLIMATES

Approximately 20% of all fatal traffic crashes in India involve riders of motorized two-wheelers. Head protection of two-wheeler riders is therefore a very important issue. This paper reports the results of a survey of patterns of motorcycle helmet use in Delhi, and the design details of a more comfortable helmet. The survey results were used as guidelines for designing a safer helmet, with a better ventilating system, to promote wider use. In the new design additional protection is provided on the sides of the helmet, since our earlier studies showed that more head injuries occur on the side of the head than on the top. A low-cost locking device has also been developed with which the helmet can be secured to the vehicle when not in use. All these design features are incorporated into a stylized product form. The new design is being marketed by a Delhi-based manufacturer and has received a very favourable response in the market.
