Improved safety with TG’s
own technology
In a front collision, a driver’s body makes a sudden stop slightly
after the car stops because there is a space between a driver and
an instrument panel and a steering wheel. This fact generates stronger
collision impact against him. In many cases he is injured by the steering
wheel and other components around it.
TG developed a SRS knee airbag to ease the impact by restraining a
driver in a split second. It is stored under a steering wheel, and
opens at the time of collision to restraint his legs under his knees.
It controls his posture to prevent injury.
The most difficult part in our development was to find the right way
of opening the airbag. We used our own technology to fold and open
it so that the knees are protected when the airbag stored in a small
space under a steering wheel opens. It was introduced to a mass-produced
car in fall in 2002 for the first time in Japan.
Severe safety evaluation with CAE in an impact
test
The biggest issue in developing an airbag is how safe it is in collision.
We put our emphasis on analyzing and evaluating it when we develop
new products.
CAE including safety simulation technology in collision and side effect
evaluation technology used in assuming various accidents or collisions
have been developed to improve the ability of safety devices.
Where a dummy is shocked and how strong it is are measured in an impact
test very similar to an actual accident using an impact sled test
device. We effectively use the test results in developing and assessing
products. |
