Is there an accident when the airbag is deployed?

The regulations are like this, a head-on collision: 13 km h airbag must not detonate, 13-18 km h is a blurred area, can detonate or not, 18 km h or more must detonate.

In other experiments, we also have angular collisions, cylindrical collisions (simulated hitting large trees, power poles, etc.), which are according to the development requirements.

In addition, the upstairs is not right, for the side airbag and the curtain airbag, the side impact is required to detonate, for some high-end cars, the curtain airbag has an anti-rolling function, and the curtain airbag should be detonated when the car rolls.

But in absolute terms, an airbag detonation does not necessarily mean an accident, and sometimes it can also occur due to development defects or extreme road conditions. Let's talk about extreme road conditions, such as very bumpy roads, washboard roads, etc., but the chances are very small.

The airbag is basically popped out after an accident.

The computer board of the airbag is usually located in front of or under the gear lever.

There is an air belt in the car

The place of the bag is the airbag.

Use a computer airbag system to detect the fault, and then repair it according to the meaning of the fault.

If there is no fault, the computer can directly clear the fault.

If you can't solve it, you can go to No. 11, District 13, Wuzhong Auto Parts City, Minhang, Shanghai to help you solve the problem.

In the event of an accident, the airbag will automatically open in the event of a sudden change in speed, such as a brake failure and a rear-end collision.

Airbag Deployment Principle: A minor collision will not open an airbag. Generally speaking, there are two conditions for the frontal airbag to work:

Angle of impact and velocity of impact. Different models have different working conditions for airbags. In general, the airbag works when it collides at a 30-degree angle to the front of the vehicle at a speed of 60 km/h.

And when the car rolls over, in a side impact, or in a rear collision, the airbags are not inflated. At this time, even if the airbag is inflated, it will not help the driver and passengers. Another point is that for the impact velocity, the airbag system measures the deceleration of the vehicle after the impact, so when doing the safety crash test, the car is generally hit straight against the wall that cannot be moved and deformed, and the deceleration is relatively large.

Necessary conditions for airbag opening:

a, the speed of the vehicle is generally more than 50 kilometers per hour, but the key factor is the acceleration at the time of the collision (in the national identification test, the instantaneous acceleration of the collision is about -40g;

b, frontal driving;

c. Collision object: rigid wall or obstacle;

e. The rigidity of the collision object: the effect of the vehicle hitting the wall at a speed of 50 kilometers per hour and hitting the sand pile is completely different, so 50 kilometers per hour is only a relative speed, and the airbag will automatically open only when the actual collision meets the conditions.

This is not absolute, it may have been accidentally detonated while repairing the vehicle's circuitry. It's also possible.

If the safety parameters of the car are normal, the airbag is an accident.

When a car airbag pops out, it's a big accident.

A car airbag burst is considered a major accident in the car, and the airbag will not pop off until it has suffered a violent impact, and basically such a vehicle has been unrecognizable. Although some vehicles are not damaged by a large collision, but just happen to hit the induction position of the airbag and cause the airbag to pop out, but after the overall replacement of the airbag, it will still be defined as an accident car, which will not only reduce the safety performance of the car, but also affect the secondary sales of the car.

Conditions under which the airbag is deployed

1. In the event of a traffic accident, if the speed is greater than 50km h, and the acceleration in the opposite direction reaches more than 40g at the moment of collision, then the condition for airbag opening has been reached.

2. You need to look at the angle of the collision of the vehicle, if it hits the vicinity of the airbag sensor, then the airbag will also be opened, generally between 60 ° on the left and right sides of the left front of the car, it will touch the sensor, and the airbag will be opened.

3. If the vehicle needs to hit the wall or obstacle, the airbag will be loaned, if the item is only used to hit the airbag sensor, it will not trigger the airbag to open. The deployment of the airbag has a certain relationship with the speed of the vehicle.

First of all, the airbag is generally caused by two reasons, the first is that an accident occurred, and the second is the design flaw of the car, such as the collision sensor is too sensitive, and the airbag will be popped out after a slight scratch, etc., in this case, it must not be regarded as an accident car.

The electronic airbag airbag system is a passive safety protection system, which works in conjunction with the seat belt to provide effective collision protection for the occupants. In the event of a car collision, car airbags can reduce the rate of head injuries by 25% and the rate of facial injuries by about 8 0%.

The airbag was first proposed by Hetrick in August 1953 and obtained the American patent for "automobile cushioning safety device". With the formulation of vehicle safety standards in various countries, the equipment rate of airbags is getting higher and higher. The airbag installation rate in Europe, the United States, Japan and other countries has reached nearly 100%.

It is mainly composed of airbag sensors, anti-collision airbags and electronic control devices. The driver's side crash avoidance airbag is installed in the steering wheel; Occupant-side crash avoidance airbag devices are typically mounted on the instrument panel. The airbag sensor is installed on the left, right and middle of the cab partition; The airbag sensor and airbag system in the middle are mounted with electronic controls.

Hello, if the airbag pops out after the impact, it must be an accident car, if it is an airbag failure popping out, then it doesn't count [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

A full airbag is a passive safety system device that airbags when a car crashes.

The pressure sensor of the system.

and accelerometers in the ECU.

If the conditions of the airbag are met, the airbag will be inflated and popped out at the same time to protect the driver's head and chest, so as to ensure personal safety.

What are the conditions that need to be met for the airbag to pop out?

Collision angle trigger sensor: The airbag does not pop out for no reason, it is equipped with a sensor, and if the car does not touch the airbag's sensor when it collides, the airbag will not pop out. Generally, if there is a serious frontal collision, it will only pop normally, but if the collision angle of the vehicle is wrong, such as the headlights, front wheels, or the back of the car, the airbag may not be deployed.

Speed and collision object: In addition to the collision angle, the deployment of the airbag is also related to the driving speed and the collision object. When the vehicle is traveling at a speed of more than 50 km/h and the collision object is rigid, the airbag will be ready to deploy.

If the speed is less than 50 km/h, the airbag may not activate when it stops crashing into a vehicle of the same class. Suppose it's a pile of sand and mollusks.

And so on the general safety argument that the airbag will not pop open.

Where did the airbag pop out?

Normally, car manufacturers install airbags in the main driver and co-driver. We don't seem to have a trace of the steering wheel.

And on the outer dial in front of the co-pilot, is where the airbag is deployed. The thinnest of these places is about the thinnest point, and when the gas starts to expand, it pushes through the weakest points and then quickly pops out.

If 23 airbags pop open at the same time, will it happen? The foreigner drove the car directly! Ling Jinheng.

Yes. Because the airbag of the car will only be deployed in an emergency, and it is a safety configuration designed to protect the passengers in the car after the vehicle is violently impacted, the airbag deployment is a major accident compared to other failures.

Airbags are mainly used to protect the safety of the driver and co-pilot passengers, cushion the life of the front passenger in case of danger, buffer the impact force encountered in the front, and protect the head and chest, while the side airbag system is used to protect the safety of passengers in the event of a side impact and vehicle rollover.

It is generally installed on the door of the car. In the event of a severe side impact, the doors will be severely deformed, and the side airbags can effectively protect the driver and passengers in the vehicle from injuries to the waist, abdomen, outside of the chest and arms caused by a side impact, protecting the lives of passengers and drivers.

The following are the precautions for the use of airbags:

1. Fasten your seatbelt: Airbags must be used with seatbeltsIf you don't fasten your seatbelts, even if you have an airbag, it can cause serious injury or even death in the event of a crash.

2. Keep a distance: Keep a suitable distance from the airbag when riding in the car.

3. Item placement: Do not place items in front, above or near the airbag, pay attention not to place items in front, above or near the airbag, because these items may hinder the airbag from inflating or being ejected in an emergency, causing greater danger.

4. Driving habits: To ensure that the airbag really plays a safe role, the driver and passengers must develop good driving habits and ensure that the chest is kept at a certain distance from the steering wheel.

5. Avoid high temperature: avoid high temperature The components of the airbag device should be properly kept, and should not be placed in a high temperature environment above 85 degrees for a long time.

When an airbag is deployed, it is a major accident. The airbag of the car will only be deployed in an emergency, and it is a safety configuration designed to protect the passengers in the car after the vehicle is violently impacted.

Precautions for proper use of airbags:

1. The airbag must be used together with the seat belt, if the seat belt is not fastened, even if there is an airbag, it may cause serious injury or even death in the event of a collision;

2. Keep a suitable distance from the airbag when riding;

3. Do not place items in front, above or near the airbagPay attention not to place items in front, above or near the airbag, because these items may hinder the airbag from inflating or being ejected at the time of emergency, causing greater danger;

4. To ensure that the airbag really plays a safe role, the driver and passengers must develop good driving habits and ensure that the chest is kept at a certain distance from the steering wheel;

5. The components of the airbag device should be properly kept, and it should not be placed for a long time in the high-temperature ring environment above 85 degrees;

6. Do not change the airbag system and the surrounding layout without authorization, do not change the wiring and components of the system without authorization, and do not change the bumper and the front structure of the vehicle at will;

7. The airbag is a disposable product, and each airbag can only be used once, and it must be returned to the factory for a new airbag after detonation.

Everyone who buys a car knows that there is a safety device inside the car called Yu Chongqing airbag.

Whenever a car accident occurs, this airbag will explode to block the impact for the person in the driver's seat. There are also some special circumstances that cause the airbag to not be able to deploy in time when the box is drawn. Under what conditions will the airbag explode normally?

For some ordinary cars, if the speed exceeds a certain limit and does not change for a long time, then the airbag may explode, because the faster the speed, the faster the fuel, at this time, the system on the car will automatically identify that the person is in danger, so as to quickly pop the airbag to save the driver's life. And when you are in the driver's seat, be sure to wear a seat belt.

Because when the airbag pops out violently, it will suddenly make people unable to maintain their shape. For your own safety, be sure to rent a rental and fasten your seatbelt first. <>

In a car accident, the car suddenly hit something sharper, and there was a violent vertical impact. In this case, the airbag will pop out normally, because each car has been set when it is designed, and once the car support is hit more seriously, it will automatically pop out, and people do not need to press it themselves. For some people, when they encounter danger, they can also manually press the airbag by themselves, so as to save their lives from the danger of car accidents.

In normal times, be sure to check regularly whether the airbag can be deployed. After all, sometimes because the airbag has not been used for a long time, the dust in the airbag will affect the airbag and cannot be ejected in time. For the sake of your own life and health, you must check the airbag settings regularly, and do not change the position of the airbag at will.

The car is driving too fast, the car hits something harder, when a car accident occurs, the steam crack spring car sensor is strongly hit by the outside world, the car is used for too long and slips, and the source will let the car's airbag burst out, which is an auxiliary role, which can protect the safety of the owner to a certain extent.
