| [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. |
