Today, along with the strong development of technology, it is accompanied by the optimization and the more complete car safety systems. Thanks to these systems, people in traffic will reduce risks while traveling. However, among many people using cars, not everyone is knowledgeable about this safety system in the most thorough way.
A car safety system is always divided into two distinct types of features: passive and active features.
In order to protect the passengers and drivers present in the car from unwanted injuries and accidents, cars should have this passive safety feature. After the active safety feature is activated but fails, the passive safety feature is now considered the "last layer of defense". Since then, we have envisioned somewhat the importance of this security feature is not it? And Thanh Phong Auto Find out about passive safety right here!
Crumple Zones is a very important and special area. Because it is designed not only to distribute collision force across the board but also to absorb collision forces, in order to reduce the impact on the passengers sitting in the car. At the same time to avoid forces focusing on a certain position.
Before each car is designed, manufacturers must conduct careful analysis and calculation of dangerous hotspots and possible collision forces. This calculation and analysis aims to:
Therefore, in some test tests of NHTSA or Euro Ncap, they all use fake mannequins placed in the car and conduct a crash test at different angles. After the vehicle collides, they can calculate, measure and check the extent of the collision of the traffic as well as the passengers present on the vehicle.
According to the structure, size and design of each vehicle, the Crumple Zone will be designed completely different. Therefore, in some crash tests we may come across some Crumple Zone vehicles that will be completely shattered, but there are some cars that only have a small amount of broken. Depending on the intentions of each car manufacturer, it may not be a good break. The most important thing here is that after each collision, to ensure the best big injuries occur and the passengers are protected to be the safest and best.
The frame surrounding the car cabin is one of the core details, ensuring the safety of the passengers sitting in the car after a collision occurs. The cabin frame is the second main layer after the first layer of protection is the absorption area. Therefore, to be able to avoid injuries to people in the car to the maximum extent, this cabin frame must be hard to deform and very hard.
In order for passengers not to be injured by deformed frames after an accident, the parts such as the accelerator, control panel, brake pedals, steering column, hood, etc. must be set up by the garage. so that when problems occur they will be pushed inwards as much as possible.
On the other hand, after a collision, so that passengers can get out quickly by themselves in all cases, the car door parts must be specially designed such as: Being able to close the door before the incident. happens, opening the door easily after a car collision…
In particular, in order for people in the car to not be injured in a bad situation such as a car rolled many times, the hood must also be reinforced with the most certainty.
One of the most dangerous parts when a collision occurs is the side of the car. If this section is not designed properly, the possibility of casualties is very high.
Therefore, the car manufacturers when designing the car side need to ensure the hardness as well as the safety for passengers when unfortunately there is a collision. Most of the luxury cars or luxury cars are very well equipped with the transmission mechanism and the force absorption mechanism. Inside the structure of the car will be designed more foam pads to ensure a certain softness and thickness.
In the event of an accident, in order to reduce casualties to a minimum, the airbag is one of the last layers of protection. This is the direct contact with the passengers inside the car.
The airbag is considered one of the great inventions to be able to prevent catastrophic unintended accidents. However, when we are using only the airbag without the straps, the airbag can become an indirect "double-edged sword" causing us injury. Because at this time, the upper body will be pushed by the airbag to a number of positions such as the side door, glass, ... causing the person inside the car to fall into a passive position ..
Frontal Airbag - Frontal airbag is usually arranged in two positions: the right row and the row on the taplo section in front of the sub-seat and on the steering wheel bar.
For frontal airbags, in some cases when the airbag inflates too strongly, it can cause injury to passengers in the vehicle. Therefore, there are many other car manufacturers today equipped with quite a lot of "smarter" technology for this type of airbag, especially luxury car manufacturers.
The system will calculate and analyze whether or not to inflate the airbag directly in front, which side to open, one or more of them, and most importantly, how much force to extract when it is "aware" about There was a collision.
Based on the data collected from the sensor, the most appropriate airbag inflating force will be decided:
Currently there are 2 common types of airbags:
Normally all cars will have all 2 types of airbags if they are equipped with an airbag, but only a few models only have curtain airbags. Because the distance between the outside collision object and the passenger is very close, the supplementary airbag may inflate at a faster rate than the direct air bag, if the airbag does not inflate in time. , in time, the situation of casualties is very high.
Protection of the victim's body is the effect of the hip airbag, while the curtain airbag has the duty to protect the shoulder and head of the passenger. Both types of airbags will often be fitted to high-end, luxury or optional vehicles as both are very expensive.
After many collisions, most of the victims' legs were injured, so many automakers designed this airbag to protect the legs of the passengers in the front row. .
This type of knee airbag will usually be arranged in 2 positions:
This type of central airbag helps to reduce the lowest rate of casualties for passengers in the car when there is an accident from the side of the car.
Due to the strong impact from the outside, when there is no central airbag if there is only one person sitting inside the car, there is a possibility that the person will be thrown to the opposite side. Or the case of many people in the car will be very easy to collide with each other.
However, with the appearance of the central air bag, when there is a collision, this airbag acts as a smooth wall to prevent and minimize casualties. Central airbags will usually be arranged in positions such as the top of the hood in the rear seat, the side of the driver's seat.
To help passengers slip until a collision occurs, this type of airbag will be located just below the passenger seat. Padded airbags will be combined with seat belts to help keep passengers firmly seated.
A seatbelt airbag is supposed to help hold the victim in a chair so that the best chance of casualties can be minimized when a collision occurs. This type of airbag airbag is usually arranged by the garage right inside the belt. In addition, the seatbelt airbag has an additional layer of protection right in front of the passenger's abdomen to help reduce injuries to the ribs and chest.
The only difference from this air bag to the air bags mentioned above is the pedestrian airbag mounted on the hood of the car. In the event of a collision between the vehicle and the pedestrian, this air bag helps to reduce pedestrian injuries to the lowest possible level. Airbags will cover the hardest areas on the front of the vehicle when a collision occurs.
A 3-point seat belt is a very important part in protecting the life of passengers in a car in the event of a collision, although it is an extremely simple invention.
It is especially important that passengers are seated in their original position when an accident occurs. Therefore, all positions on cars today are designed by manufacturers, so when you ride, remember to install seat belts.
Currently, seat belts have made great improvements, helping it develop to its full potential:
The headrest is also one of the most important passive safety features on cars, so it is fitted on all seats including the front and rear seats. Preventing the phenomenon of "Whiplash" occurring in collisions is the task of headrest.
In the first phase of a rear-end collision, your head will be pulled backwards and the next when your vehicle is stopped, your head will be pushed forward, this is called the "Whiplash" phenomenon.
So is the phenomenon of "Whiplash" dangerous or not? Of course the "Whiplash" phenomenon is very dangerous. When your head is too far from the headrest position, in the event of a collision, your cervical vertebrae are very easy to break.
In particular, the headrest on the car if as close to the nape as possible and the headrest should be at least as high as the center of the head, thus preventing the phenomenon of "Whiplash" from happening. Therefore, you need to pay special attention to adjust your head accordingly when boarding to avoid the "Whiplash" situation.
Posts above Thanh Phong Auto shared with you 6 passive safety features in cars today. Although these features are only for "fire fighting", they are very important to our survival in the event of an unfortunate collision. Therefore, to be able to use the car as well as protect our safety, you should remember and understand these features.
