Wearable airbag for the elderly

Neat idea. [Link]

The 1.1 kilogramme (2.4 pound) airbag looks like a traveller's waist pouch but inflates in one-tenth of a second when sensors detect the wearer has taken a tumble.

The Tokyo-based company, Prop, unveiled the 148,000 yen (1,400 dollars) device at a fair of products for the elderly and people with disabilities.

It protects the back of the head and the buttocks with two inflated bags that contain 15 litres (3.9 gallons) of gas each.

Elderly people are more prone to injury when they fall due to their brittle bones.
