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 airbags 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. Air bags 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.
