Airbag pedestrian (Pedestrian Airbag)
Standard vehicle, safety and standardization
part of Accidents That happens in the streets and urban passages between cars And pedestrians or sometimes Cyclists is! In most of this Accidents, Unfortunately serious damage to Pedestrians enters and they may lose their lives during these incidents. Parts of the car, such as the car hood, pillars and windshield, due to their hardness and rigidity, cause the force from the car to the pedestrian to be transferred to the pedestrian without any drop and lead to physical injuries.. The amount of this type Accidents It is more in cities, and the more urban pedestrian population is, naturally, the probability of these accidents increases and there is a need for a deterrent factor to reduce the number of casualties in such accidents..
According to statistics Car accidents With pedestrians and the resulting deaths in the city, some of the Automobile manufacturers In addition to the lives of the passengers carThey decided that the lives of pedestrians were also important to them The immune system to create a system that protects the body and life of pedestrians in these accidents and reduces the possibility of serious injuries and death.
Auto parts and standardization
This system is activated between speeds of 20 to 50 km/s and at temperatures of minus 20 to plus 70 degrees Celsius.. According to studies, in 75% of accidents involving pedestrians, the average speed of the car was 40 km/h. It is interesting to know that the control part of the pedestrian airbag is so advanced that it detects the shape of the legs or the shape of the pedestrian's head and then activates it. Airbag pedestrian does.(Related)
The important thing about this system is that it should not be in the front sections car Changes by the owner car take place and make any changes non-standard (Adding or subtracting equipment and…) Because with appearance changes, the information sent by the sensors to the control part is accompanied by errors and the system may Airbag pedestrian It will not work well.
Standard vehicle inspection
The reason for not using these airbags in the back car Also, of course it is because when driving with car In the reverse gear mode, the speed of the car does not reach as much as if Accident With the passerby, he will be seriously injured and on the other hand, the times that car It moves much less in reverse gear than in forward gear! But in general, Airbag pedestrian It was able to make a big change in the systems Car safety brought about and problem Safety of pedestrians also brought up.
How does the passenger airbag work?
Explosive release mechanism(Pyrotechnical Release Mechanism) This system releases the hood by removing the pins Airbag pedestrian Once activated, move it 10 cm. As the hood moves, the distance between it and the rigid parts under the hood, such as the engine, increases, and the hood acts like a shock absorber and absorbs the impact of the passerby..
Inspection of cars, motorcycles and power industries
If this function is not performed, the hood will not be moved and the passerby will be thrown on it, the hood will be pressed down and out of its shape.. Compression of the hood makes the hood to the upper part engine hit, because of the collision of the passerby with the hood car After changing the shape of the hood, the upper part of the engine, due to its high stiffness and rigidity, not only prevents the hood from hitting, but also imposes an upward force on the passerby, and it can be very dangerous for the passerby..
after Performance Activation mechanism AirbagThe produced gas fills the airbag. By filling the gas inside Airbag pedestrianBoth the hood and parts of the front are moved by 10 cm car Like pillars, wipers and the lower edge of the windshield (About a third of the way down the glass) which the passerby may encounter and get injured by Airbag pedestrian It is interesting to know that the control section Airbag pedestrian It is so advanced that it detects the shape of the legs or the shape of the passerby's head and then activates it Airbag pedestrian does.
