An airbag helmet for cyclists has been developed by Swedish inventors, Anna Haupt and Terese Alstin.

The Hövding helmet inflates in a tenth of a second and contains sensors that detect abnormal movements to inflate the airbag prior to impact.

Unlike standard helmets, the Hövding is not placed on the head, but as a collar around the neck, which inflates and protects the head in the event of an accident.

The device costs £335 and has been cleared by European safety standard regulators. The Hövding helmet can be customised with exterior patterns and is waterproof. It is also sold with a rechargeable battery.

Sound like something from the future?
