Safety Steering
S.R.S. (SRS stands for "supplemental resistant system").
The air bag is a "European" style head and face bag, which means
it is designed to protect primarily the head and face during a
frontal collision.
An important point to note about the Safety Steering S.R.S.
is that it is designed to supplement the existing seats belts in
a vehicle, not to replace them. Nor is the system designed to be
a replacement for factory-installed air bags 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.
Before the bag will deploy, the crash sensor has to experience
an impact force of about 7 G's (seven times the force of
gravity). For most vehicles, this would be the equivalent of
hitting a solid barrier at 20-40 km/h, or hitting another
vehicle at a speed of about 40 km/h. The actual crash speed at
which at which the bag will deploy depends on so many variables
(angle of impact, the relatives mass of the vehicle or object
struck, the stiffness of the body and chassis, etc.), that it's
impossible to give an extra speed. The only thing that can be
said with certainty is that the air bag will deploy when it is
needed.
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.
When colliding frontally to a solid object with a speed less
than 8 km/h, the bag will not deploy. When the speed is between
8 and 25 km/h the possibility for the air bag to deploy is
relatively higher. When the speed is over 25 km/h the air bag
wiil deploy on impact.
Remark: The speed on impact and solidness of the object, the
angle of impact (not more than 30degrees with frontal collision
with another vehicle) and various other factors make an
influence on the deployment of the airbag.
The air bag will not detonate at instances when overturning or
collision from behind. To install the air bag, an approved
technician selects the appropriate module for the application,
removes the stock steering wheel and installs a new steering
wheel that contains the airbag.
Manufacturing Safety Steerings SRS products are
manufactured as a OEM product in accordance with ISO/TS
16949:2002 quality and management system for the Manufacturing
of Automotive Safety Restraint Systems (Air Bags) with product
design and development.
Testing The air bags are tested in compliance with ISO/IEC
17025:1999 General Requirements for the Competence of Testing
and Calibration Laboratories.
This new advanced technology not only create opportunity for our
customers to comply with safety requirements of various
installations and people, but they have the advantage to sell
their products on markets which was not reachable before.
The Safety Steering also saves lifes and injuries.
We are proud of our excellent back up service, both technically
and stock. |
