Airbag Safety Steering Systems.designer handbags[1] , S.botas[2] ,
R.meizitang slim[3] , S. or the supplemental resistant system is an
European style airbag which includes a head and face bag, which means in
effect that it is does protect the head and face during an upfront
collision. The Safety Steering S. R. S. is designed in addition to the
existing seatbelts in a vehicle and do not replace them. The system is
not designed to replace factory installed airbags that have been
deployed in the accident.
Crashed tests show that seat belts do a fairly good job for protecting
the driver's body in a frontal collision, but many not always keep the
driver's head from hitting the steering wheel (which can result in
severe injury or even death). The air bag is designed to provide
additional protection to the factory seats belts by adding an extra
margin of safety. When the bag deploys during a crash, it "fills the
gap" between the driver and the steering wheel. The inflated bag
provides the cushion necessary to to absorb the force of the impact and
prevent the driver's head or face from striking the steering wheel.
The Safety Steering air bag features a "mechanical" impact sensor, which
is the simplest, most reliable type of triggering mechanism. Unlike most
original equipment air bag systems that rely on a complex web of crash
sensors, safety sensors, wiring and an electronic control module, the
mechanical impact sensor is virtually fail-safe. The crash sensor, which
is self-contained within the steering wheel air bag module, consists of
a steel ball within a tube. When a frontal impact of sufficient force
occurs, the ball is dislodged and slides down the tube, releasing a
firing pin that ignites the inflator. The bag deploys in 30 to 55
milliseconds (less time than it takes to blink your eyes), which is just
as fast as an original equipment air bag.
The crash sensor has to experience an impact force of about 20 G's
before the bag will deploy. That is seven times the force of gravity.
This would be the equivalent of hitting a solid oobject at 20-40 km/h,
for most vehicles, or hitting another vehicle moving at a speed of about
40 km/h. The crash speed at which the bag will deploy depends on many
variables such as the angle of impact, the stiffness of the body and
chassis, the relatives mass of the vehicle or object struck, etc., The
only thing that can be said with certainty is that the air bag will
activated in time of need
One of the advantages of having an air bag with a purely mechanical
crash sensor is that it eliminates the need for wiring and expensive
electronics. This allows the crash sensor to be packed with the inflator
in the air bag module, which greatly simplifies replacement and
installation.


It also means the system will function independent of the vehicle's
electrical system. Because the air bag with its purely mechanical crash
sensor can be packed as a self-contained unit, it can be easily
installed on just about any vehicle - provided there's a steering wheel
available for the application designed to accept the air bag module -
and that the required crash testing has been done to make sure the crash
sensor has the correct level of sensitivity for the vehicle.
Though it's relatively simple to replace a steering wheel and bolt on
one with an air bag, the safety steering wheel isn't a
"one-size-fits-all" air bag. The bag has to "fit" the application, which
means different inflators and crash sensors are requires for different
vehicle applications. An air bag with a crash sensor that's set for a
light-weight Chana LDV, for example, may not deploy at the right speed
if used in a heavier vehicle such as a full-sized Toyota Landcruiser. So
currently five different inflator assemblies make up the air bag system.
With ann upfron collision at a speed of less than 8 km/h, the bag will
activate and not be deployed. At the speed of 8 to 25 km/h the
possibility for the air bag to deploy is then relatively higher. When
the speed is over 25 km/h the air bag will definitely deploy on impact.
The angle of impact (not more than 30degrees with frontal collision with
another vehicle), the speed on impact and solidness of the object, as
well as various other factors has a direct influence on the deployment
of these airbags.
