Airbags for vehicles SRS Steering Safety Airbags
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 mechanical impact sensor is an impotrtant feature of the Safety Steering Airbag which is a simple but extremely reliable type of triggering mechanism. Unlike most original equipment air bag systems that rely on a complex web of crash sensors, wiring and an electronic control module, safety sensors, the mechanical impact sensor is so to say 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, and triggers a firing pin that ignites the inflator. The bag is ejected and air filled in 30 to 55 milliseconds 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 20 G’s which is seven times the force of gravity. This would be the same as driving into a solid object at the speed of 20-40 km/h or driving into another vehicle at a speed of 40 km/h. The collision speed at which the bag will be ignited and deploy, depends on many variables such as the angle of impact, the stiffness of the body, the stiffness of the chassis, the mass of the vehicle or truck, etc., What can be said with certainty is that the airbag will activated when needed.
A great advantage of airbags with a purely mechanical crash sensors 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 cause the system to function independent of the vehicle’s electrical system. Because of the fact that the airbag’s mechanical crash sensor can be packed as a self-contained unit, it can be easily installed on most vehicles as log as there is a steering wheel for the application designed to accept the air bag module and that the neccessary crash testing has been done to make sure the crash sensor has the correct level of sensitivity for the vehicle.
It is a simple task to replace a steering wheel and bolt but the safety steering wheel does not fit all size airbags. The bag has to fit the application. Different size inflators and crash sensors are required for different vehicle applications. When a light-weight motor vehicle is fitted with an air bag with a crash sensor that’s set for this specific vehicle, it may not ne ignited and activated at the right speed if used in a biiger vehicle such as a truck or landcruiser. Five inflator assemblies make up the air bag unit.
In the case of upfront collision at a speed of less than 8 km/h, the airbag will activate and not be deployed. At the speed of 8 to 25 km/h there is a higher possibility for the air bag to deploy. At a speed is more that 25 km/h the air bag will definitely be activated and deploy on impact. The angle of impact should not be more than 30degrees with frontal collision with another vehicle, solidness of the object and the speed on impact, and various other factors has an influence on the deployment of airbags for safety steerings.
The air bag will not deploy when overturning or collision from behind. Approved technician are required for installation of the airbags and they will select the appropriate module for the specific application, then remove the stock steering wheel and install a the new steering wheel which includes the airbag. Ths product creates opportunity for our customers to comply with safety requirements. They also have the advantage to sell their products on markets which was not in their each before. Safety Steering Airbags saves lives and limits injuries.
