Airbags have been protecting car drivers and passengers in dangerous collisions since the late 1980?s and we have recently seen a number of products which adapt the technology to protect those outside the car too. From the Hovding — a wearable airbag for cyclists in Sweden — to the Volvo V40 — which features an external airbag to shield pedestrians, companies worldwide are protecting a variety of at-risk consumers. Now, the Wolk Company in Belgium have developed another specialized product, identifying and protecting the area most in danger for a different high-risk group — the elderly. Wolk — meaning Cloud in Dutch — is a wearable airbag for elderly people which is worn around the waist, fastened like a seatbelt and automatically inflates to protect the hip and lower back of the wearer when it detects a fall.
