Hövding is the world's first airbag bicycle helmet, invented by Anna Haupt and Terese Alstin in Malmö, Sweden in 2005. After seven years of research, development and testing, the Hövding was launched in November 2011. The two founders Anna Haupt and Terese Alstin left the company in beginning of 2015 when the new external CEO didn't agree on the company visions.
Hövding was initially created as a master thesis for the founders' Master of Industrial Design at the Faculty of Engineering at Lund University in Sweden. Their studies included the comparison of accelerometer data from bicycle crashes against 'typical' cycling. The Hövding contains accelerometers that detect these unusual movements which then deploys the airbag if the movement patterns match the profile of a crash. Each Hövding airbag also contains a " Black Box" that records the accelerometer data 10 seconds before a deployment. This data can be used by the Hövding developers to improve the product. The Hövding collar is constructed of a waterproof material, and has interchangeable fabric "shells" that allow colour customisation.
Hövding is CE certified after undergoing an extensive process for approval by SP Technical Research Institute of Sweden. CE marking is required for a cycle helmet to be able to be sold in Europe and certifies that the helmet complies with the requirements laid down in the EU Directive for personal protection equipment.
In March 2015 Hövding 2.0 was released. There are a number of changes that were added based on feedback from users. These include improvements to the weight, comfort and change in location of the USB port.
