Developed in 1950 and introduced commercially in 1980, the airbags are all new cars, trucks and SUVs are needed. Before their debut, drivers relied on for security protection in the event of a collision accident. Due to the changing needs of motorists, a new security technology was required.
Ford Motor Company has developed a test air bag system in 1971. E 'quickly gained the attention of the entire automotive industry and was considered far superior toAlternative seat belts. In fact, it was believed at the time to replace the new security measure taken by a safety belt all day.
Today, all vehicles, driver and passenger side airbags. Some car manufacturers have installed them to protect rear seat passengers. In this article I will explain how they work and describe some security issues have been raised.
How the technology works
If a driver involved in a traffic accident,their vehicle stops suddenly as their bodies continue to go in the same direction. The challenge is to eliminate the momentum before the body of the driver of an object hits (like the steering wheel), without causing any damage. This is the foundation, is designed for the airbag technology.
The system consists of bag (usually of a nylon material), a crash sensor, and a device that inflation causes together. The sensor has two jobs. First, a control switch andidentified if it has become tilted. This mirroring occurs when something is a level of energy equal to colliding with a wall at about 15 mph. The crash sensor of the second task is to provide an electrical signal that tells the airbag inflation provision.
After receiving the electrical signal from the crash sensor, sodium azide mixture of inflation and potassium nitrate to produce nitrogen gas. The explosion immediately filled with nitrogen, the airPocket.
Security concerns
the first drafts airbag has drawn criticism for several reasons. First, many people claimed the technology was limited, because the bags must be placed at the front. In the event of a collision site, would offer little protection from evil. Secondly, were emerging evidence that air bags dangerous, this session was to close at the time of distribution. Thirdly, children are particularly vulnerable to damage caused by their height.
AirbagThe technology has evolved over the last twenty years. car manufacturers have ways to deploy them on the passenger side, weight, size, location, and developed the special circumstances of the collision. What's more, the airbags are now routinely installed in the doors, the driver and passengers with improved side impact protection.
E 'likely to see a steady development in airbag technology for the next decade. Must be a reliable method to reduceInjuries and fatalities in road traffic.
