Airbag Safety SRS Steering Airbags
Airbag Safety Steering Systems. S.R.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.
Various tests indicated that seat belts do a good job for driver body protection in a up front collision, but they do not always keep the driver’s head from colliding with other objects , normally the steering wheel, which can result in injury and in certain cases death. The air bag is designed for extra protection in addition to the original seatbelts and is adding an additional margin of safety. When the bag fills the gap between the driver and the steering wheel when it deploys. A cushion is the provided to to absorb the force of the impact and prevent the driver’s head or face from hitting the steering wheel by the inflated airbag.
The mechanical impact sensor is an impotrtant feature of the Safety Steering Airbag which is a simple and effective type of releasing mechanism. Airbag systems that rely on a complex web of crash sensors like wiring and an electronic control module, safety sensors, the mechanical impact sensor is so to say fail-safe can now be replace with this system. The crash sensor, which is self-contained within the steering wheel air bag module, consists of a steel ball within the tube. When a frontal impact with force occurs, the ball is dislodged and slides down the tube, it activates a firing pin that ignites the inflator. The air bag is then ejected and deploys in 30 to 55 milliseconds which is as fast as an originally installed air bags.
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.
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.
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.
