Hovding_ air bag helmet

jamie had show me this picture, which i think it has a interesting shapes and it can also become
a fashion. I went and do some research on this, i found it is design by Swedes Anna Haupt and Terese Alstin. Hovding is a collar for bicyclists, worn around the neck. The collar contains a folded up airbag that you'll only see if you hapen to have an accident. the airbag is shaped lik a hood, sourrounding and protecting the bicyclist's head. The triggr mechanism is controlled by sensors which pick up the abnormal movements of a bicyclist in an accident.
