Introduction:
Distribution of the airbag in the vehicle forward (passenger seat), the side (vehicle front and the rear row) and the roof three directions. Outside the vessel equipped with the airbag system are printed Supplemental Inflatable Restraint System, referred to as SRS) message, directly translated into Chinese, should ldquo; auxiliary inflatable restraint system rdquo ;. It aims to reduce vehicle after the collision, the occupant due to the inertia of the degree of injury during a secondary collision.
airbags to protect the occupants of the car were safe side impact, and vehicle rollover. Usually installed in the door, in a vehicle collision can cause side door was badly disfigured that it can not open the door, the car occupants were trapped in the car, side airbags can effectively protect car occupants from side impacts caused waist, abdomen, chest outside, and arm injuries, ensure mobility and ability to escape the body of the upper limbs.
With the popularity of passive vehicle safety significance, there have been some high-end luxury cars are up to 30 a few balloon from the neck, knee, or even on both sides of the roof will be equipped with two the tubular article airbag when the accident occurs can effectively relieve the pressure from the upper roof, with a side air curtain can effectively protect the occupant’s neck and head. Knee airbag front portion is located in the driver’s seat, once opened can effectively protect the extremity of the rear passenger waist, thus can alleviate the forward momentum from the frontal collision.
Principle:
The main airbag by the sensor, a microprocessor, an airbag gas generator and the other components. Crash sensor and a microprocessor for determining the degree of transmission and the transmission signal; a gas generator based on a signal indicating an ignition operation, the solid fuel ignites to generate gas to inflate the airbag and the airbag is rapidly inflated balloon capacity is about (50-90) L . withWhen provided with a safety airbag, when inflated excess intraluminal pressure exceeds a certain value or automatically bleed part of the gas, to avoid injury to the passenger pressing. Airbag used mostly nitrogen gas or carbon monoxide.
In addition to the driver’s side airbag, but also some cars front passenger airbag installed (i.e., dual airbags standard), drivers and passengers with a similar, but the volume of the airbag to a little bigger, a little more gas is also required of it. In addition, some cars are still seats side by side door mounted side airbags.
effect:
The airbag is a striking high-tech devices on modern cars. Install a car steering wheel airbag device, usually there is no difference with ordinary steering wheel, but once the car front end collision occurred a strong, airbag from the steering wheel will instantly ldquo; jump rdquo; out of cushion between the steering wheel and driver , to prevent the driver’s head and chest impacts the steering wheel or dashboard to other hard objects. Since airbags available, it has saved many lives. Studies have shown that frontal air bag device car crash, the driver of mortality, big cars reduced by 30 percentage midsize sedan by 11 percentage, the percentage of small cars reduced 14.
