The Hövding is an airbag for your head. Hövding means “chieftain” in Swedish, and the air-helmet was designed by Swedes Anna Haupt and Terese Alstin as a university thesis project. The Hövding collar contains gyroscopes and accelerometers which constantly monitor your movements, releasing the airbag hidden within only when you’re in danger.
