5)"Airbag System" to reduce shock to the motorcycle rider during collisions

[Research and Development Aim]
Although airbag systems are already commonly used in 4-wheelers to supplement the seat belt function, there has been a demand to develop a different type of system for motorcycles due to such factors as the need for a bag with a larger area in order to offer protective effect to a motorcycle rider, who is not confined within a vehicle, as is the case with 4-wheelers. During research for the development of the system adopted here, full consideration was given to the unique characteristics of a 2-wheeler while focusing attention both on mitigating injury to the rider in frontal collisions and reducing secondary injuries resulting from the rider being thrown off the vehicle.


[Features of the Technology]
The system comprises a "front sensing bumper" with improved shock sensing performance, an ECU that calculates shock to the vehicle and vehicle running speed to make the judgment that a collision has occurred, an inflater to inflate the bag and the airbag itself.
When the ECU detects a shock, it immediately determines whether it is the result of a collision and sends a signal to ignite the inflater. The gas emitted by the triggered inflater inflates the airbag in front of the rider.
