Airbags on bikes are not a new idea. British transport researchers have been toying with the idea for many years and there is a commercially available motorcycle jacket with built-in airbags.
According to Honda, the system is comprised of the airbag module, which includes the airbag and the inflator; crash sensors, which monitor acceleration changes; and an ECU, which performs calculations to instantly determine when a collision is occurring.
When a severe frontal collision occurs, the four crash sensors mounted on the front fork measure the change in acceleration caused by the impact and convey this data to the airbag ECU, which determines that a collision is occurring and whether or not it is necessary to inflate the airbag. If the calculations performed by the ECU indicate that airbag deployment is necessary, the ECU sends an electronic signal to the airbag inflator, which instantaneously responds by inflating the airbag.
The company says the airbag can absorb some of the forward energy of the rider, reducing the velocity at which the rider may be thrown from the motorcycle and helping lessen the severity of injuries caused by the rider colliding with another vehicle or with the road. We understand the system will initially be trialled in the USA market, before a decision is made on whether to export.
