The Hövding airbag collar that we first covered in 2010 when it was originally shown off to the world by its inventors, industrial designers Anna Haupt and Terese Alstin, has now officially gone on sale.

The Hövding (Chieftain) is an airbag collar called that inflates to enclose the head of a cyclist in the event of an accident.

An air bag system for astronauts evacuating the International Space Station should allow for soft landings.
