Hövding is an invisible bicycle helmet, designed as a stylish collar worn around the neck while cycling. The collar contains an airbag that is visible only if an accident occurs. The airbag is shaped like a hood, surrounding and protecting the cyclist’s head. The inflation is triggered by sensors that register the abnormal movements of the cyclist in an accident. Sales began in November 2011 and Hövding is now available to buy in stores in Sweden, Norway, Denmark, Germany, Austria, Netherlands, Belgium and Switzerland as well as from the company’s website, www.hovding.com.
