The head airbag for bicyclists is a real thing

Dainese make a full suit that some of the MOTO GP guys wear.

Air bag is triggered by sensors - accelerometers and gyro-meters - which records the abnormal movement of the rider in an accident. The sensors then sends a signal to the gas generator for inflating.

In-depth information here.
The sensors continually monitors the rider's movements when the Chief is on. Rider 'movement patterns are divided into two categories:

Normal movements: All city and road cycling, including regular movements in connection to the bike ride, like running down stairs, unlock the bike, sudden braking and evasive action, inflating tires, etc.. categorized as normal movements. Chief does not blow up under normal movements.

Abnormal movements: Movements of the cyclist in a cycling accident categorized as abnormal movements. In an accident, the motion pattern of the cyclist quite different from normal cycling.

Therefore, the air bag is activated only in case of accidents *.

In order to distinguish these two categories of movement patterns, we first collected the movement patterns of a large number of people's everyday cycling, for many years. We have also staged all known types of bicycle accidents, and collected the cyclists' movement patterns in these accidents. Fatal bicycle accidents, we have staged the crash test dummies. Other bicycle accident, we staged with male and female stunt performers. All these movements have been collected in a database. We have developed a unique, patented, mathematical method to distinguish these movement patterns to. The method, combined with the sensors, the brain in Chief.

* It takes an abnormal motion of the cyclist in an accident for the Chief to respond. Why can not protect the rider's head chiefs of such an object falling from above, straight down the rider's head. However, this is an extremely unusual bicycle accident category.
