The U.S. National Highway Traffic Safety Administration reported 677 cyclists were killed and 48,000 were injured in motor vehicle traffic crashes in 2011. Wearing a helmet is the most effective means of protecting against a head injury. Unfortunately, fewer than half of cyclists wear them due to their unfashionable look and uncomfortableness. For cyclists who shy away from helmets, a Swedish company invented an air bag collar called the Hovding. The device is worn around the neck and has sensors that can detect a sudden change in speed or movements. If an accident is detected, the collar inflates with helium and forms an airbag protective cover around the head. Unlike most helmets it covers the neck as well as the head.
