Airbag Safety SRS Steering Airbags

Airbags and Safety Steering. S.R.S. (SRS stands for “supplemental resistant system”).The European style airbag is a head and face bag, which means in effect that it is designed to protect the head and face during an upfront collision. It is of importance to know that the Safety Steering S.R.S. is designed to supplement the existing seats belts in a vehicle and not to replace them. The system is not designed to replace 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 (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.

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.

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.

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.
