Who motorists today who do not know Airbag, Airbag is the tools usually installed on cars of upper middle class, which aims to maintain the safety of the users of the car. But do you know specifically? From the start who the inventor, is made of, to how to work Airbag ?. We discuss more about Airbag, we should study the history of the airbag. At first the air bags used in the second world war, at that time the use of Air Bag earmarked for the pilot made an emergency landing and going on crash landing. And in the year 1951 by Walter Linderer by the compressed air system, find the first prototype of the forerunner of the airbag, but not perfect, and not fast enough to save the passengers of the vehicle. Then in 1953 a ship engine engineer named John W. Hetrick find a tool designed to protect motorists, then the tool is patented under the name of the defined safety cushion pillow protectors. The invention is based on the accidents suffered by John on when traveling using their private cars, of it John racked his brain and finally John found a protective device that Allen Breed tersebut.Setelah find airbag uses sensors and safety systems. And in 1971 the Ford car company began experimenting with the airbag, and continue to do penyempuranaan the airbag, and since 1973 the Ford pair Airbag on product manufacturers Ford and automotive companies are using Airbag first is Ford.
Once you know the history of airbags, we will discuss making materials airbag. Airbag made of nylon material selection, which is the material used for making parachutes formed as a balloon. Due to the nature of the material is easy to install, and usually airbag is located, such as in this part of the steering wheel, on the panel, at the door, even on the seat of the vehicle. Airbag filled with nitrogen gas pumped from the tube in other parts of the restricted valve that has been equipped with sensors that function collision if the collision occurred in an accident, then the sensor is active and pumping nitrogen into the airbag. There is also the accelerometer, which is a tool for measuring the acceleration of a movement and mendetekdi vibration or shock, which is planted on the microchip. Position airbags are also always laid out in accordance with the anatomy of the human body, so that when the accident occurred telindungi starting from the head, body and legs. And dots airbag is located on the dashboard, airbag, steering airbags, side airbags, curtain airbags, knee airbag, seatbelt airbag, head airbag.
After knowing the history, materials and points Airbag sure you want to know the function of the airbag, as one of the safeguards you when you drive. Airbag or airbag is intended protective device for vehicle users four or more wheels. Airbag work when you drive a car accident the airbags ballooned to hold the body to avoid collisions with other devices in the car or thrown out of the car when the accident occurred. Airbag works by bulging when danger occurs and deflate when the danger has passed. So fill in your favorite car with the airbags if a safety device is not already installed on your car.
In recent decades airbags have reduced the number of deaths and serious injuries from a car accident. Based on data from the Insurance Institute for Highway Safety, the number of deaths due to collisions when seatbelts and airbags are used by 24%. So The National Highway Traffic and Safety Administration (NHTSA) issued a rule that cars made after 1998 must be equipped with airbags in the driver and passenger.
Mechanism of action of the airbag is divided into two systems, sensors and airbag modules. The sensor consists of two sensors and sensor impact deceleration. Deceleration sensor works when the car experienced a sudden reduction in speed from high speed. While the impact sensors placed in the front of the car, so the car when the clash sensors will send electrical current to the airbag module unit.
Airbag inflator module consists of, nylon bag, and cover. Located inside the steering wheel and dashboard of a passenger. Airbag modules work when the sensor sends an electric current to the inflator. Because inflator initiator get an electric current then went to work by creating a spark that is capable of burning propellant or most cars using the compound sodium azide. Where the results of this combustion will create nitrogen gas. The combustion process will produce ash and hot nitrogen gas. Abu automatically discharged into the air while hot nitrogen gas is cooled through filtration screens.
