Center airbags are a relatively new innovation in vehicle safety technology. They protect in a collision by filling the gap between two front passengers.
What Will I learn
Thus they protect them from being thrown into each other with potentially devastating force. Today we’ll discuss the types of center airbags available, how they work, and their potential benefits.
Center Airbags: Working Mechanism
Center airbags are typically triggered by sensors located around the vehicle’s frame. These sensors detect changes in speed and direction.
Let’s find out how the airbag’s deployment works in detail:
1. Sensor Detection:
The center airbag also differs from other airbags in that it inflates differently. Its deployment is triggered by a series of sensors located throughout the vehicle.
When the sensors detect a rapid deceleration or lateral force, they transmit this information to the Electronic Control Module (ECM).
The ECM then sends a signal to initiate inflation of the center airbag. ECM is a computer that is used to control various components of the vehicle.
Sensors are also connected to the front passengers’ seatbelts. They detect when a collision is imminent and prepare the airbag for inflation.
However, the sensors do not detect every type of collision. They are designed to activate only in collisions that meet certain criteria.
These may be frontal impact or rollover collisions. Some may also detect an impact on the side of the vehicle.
2. Inflation Process:
This inflation process usually occurs within the first few milliseconds of a collision.
The inflation process is instantaneous. But it only applies to a relatively small area of the vehicle’s cabin.
It means that the center airbag only inflates when an occupant is in a certain area of the vehicle.
Also, the center airbag is designed to inflate slightly slower than other airbags. This helps reduce the risk of injury while providing more cushioning and protection.
Once inflated, the center airbag acts as a buffer between occupants in the vehicle’s cabin. It works by dispersing the force of a collision over a larger area.
This reduces the risk of serious injury. Also, the cushioning effect helps to reduce the severity of whiplash and other forms of neck and spine injuries.
As compared to other airbags, center airbags are generally larger in size. This helps to provide more coverage and protection for occupants in the vehicle’s cabin.
3. Cushioning:
The center airbag helps to provide additional cushioning for occupants in the event of a collision. There is a combination of sensors, inflation devices, and other components that help to trigger the airbag’s deployment.
This helps to ensure that it inflates in the appropriate timeframe. The center airbag also works differently than other types of airbags.
For example, side airbags are designed to protect against impact from an outside force.
A center airbag, on the other hand, protects from forces that come from either side of the vehicle.
It also helps to spread out the impact force more evenly across all occupants in the vehicle’s cabin.
This provides an added level of protection for passengers. It can help reduce the severity of injuries caused by a collision.
3 Types Of Center Airbags
There are three main types of center airbags: seat-integrated, door-mounted, and console-mounted. Each type works differently and has its own unique advantages.
1. Seat-Integrated Airbags:
Seat-integrated airbags are installed directly into the cushion of the vehicle’s driver or passenger seats. They deploy in the center of the seat during an accident.
This type of airbag is most commonly used in vehicles today due to its increased protection and safety benefits.
What’s more, seat-integrated airbags are unique in that they provide additional side-impact protection.
When the airbag is deployed, it fills in the gap between the front and side airbags. With any side-impact crash, this airbag will provide additional cushioning.
It will provide protection to the head, neck, and torso. And while it won’t stop the occupant from being thrown forward, it will help to slow them down.
Their effectiveness has been tested and proven to reduce injury in case of an accident.
2. Door-Mounted Airbags:
The second type of center airbag is the door-mounted airbag. As shown in the name, the airbag is mounted on the door.
When deployed, it expands and covers the gap between the front and side airbags. This type of airbag provides similar protection as seat-integrated airbags.
But its deployment may be slower due to having to travel further to reach its target area.
Still, when compared to other types of airbags, it is more effective than a seat-integrated airbag.
With any airbag, the cushioning effect is greater when closer to the occupant.
Door-mounted airbags provide optimal protection in side impacts or rollover collisions. Here the occupant is at greater risk of injury.
It can also help reduce whiplash injuries that are common in rear-end collisions.
The use of door-mounted airbags has become more popular. Automakers look for such ways to provide additional safety measures in their vehicles.
3. Console-Mounted Airbags:
This type of airbag is mounted in between the front seats. As per the name, the airbag is mounted in the center console.
It deploys upward towards the front dashboard. Console-mounted airbags are particularly effective in frontal collisions. It provides additional cushioning to the occupants.
It is especially beneficial when a car occupant is not wearing a seat belt. It absorbs much of the force from the impact.
Console-mounted airbags are also beneficial in offset collisions. They provide a cushion to the occupant’s chest and abdomen when they move toward the side of the car during impact.
The advantage of this type of airbag is that it protects both the driver and the front passenger.
It also helps reduce head-on collisions by providing cushioning between both occupants.
So these are three different types of center airbags that have been developed to provide additional protection during a crash.
Each type has its own advantages and disadvantages. But they all provide an extra layer of protection during a car accident.
Safety Benefits Of Center Airbags
Center airbags have been found to be highly beneficial in reducing fatalities and injuries in car accidents.
Tests have shown that the center airbag works in some production settings and crash scenarios to reduce injury. But it may not work in all types of vehicles or real-world accidents.
However, the center airbag provides an additional layer of safety when used in conjunction with seat belts, side-curtain airbags, and other safety features.
Let’s discuss the types of injuries center airbags are most effective at preventing:
1. Torso:
With a center airbag deployed, the occupant’s torso is better protected against forces that may cause injury.
This includes protection from a side impact or frontal collision. Here the occupant may be forced forward into an object such as the dashboard or steering wheel.
Some center airbags are designed to keep the occupant seated during an accident.
2. Head:
A deployed center airbag can prevent contact with objects like the dashboard, steering wheel, and windshield. This helps reduce head and neck injuries in a crash.
Also, some models of center airbags come with an inflator in the headrest. This inflator helps to reduce the impact of a side collision, further reducing injury potential.
3. Back And Chest:
Center airbags can also reduce the severity of back and chest injuries in a crash. The airbag helps to absorb some of the force from an impact.
It can disperse it from the occupant’s body, reducing the potential for serious injury.
Some models of center airbags have a deflation system. It allows them to deflate gradually after the initial impact, providing additional protection.
4. Limbs:
In addition to others, center airbags can also help reduce limb injuries. They provide an extra cushioning layer between the occupant’s body and other objects in a crash.
Thus, center airbags can help limit injury severity to arms and legs. With the right positioning, the airbag can be deployed so that it wraps around the body.
This helps distribute the force of impact away from limbs and other vulnerable body parts.
Are SeatBelts Mandatory Even With Center Airbags?
Center airbags provide additional protection. But it is still important to wear a seatbelt for maximum safety.
In fact, in some states, wearing a seat belt continues to be mandatory, even with the presence of center airbags.
This is because seat belts help hold occupants in their seats during an accident. This way, they can reduce the risk of being thrown from the vehicle.
It is also important to ensure that seat belts are properly worn for maximum safety benefits.
Some states even require the use of shoulder harnesses. They ensure that the seat belt is securely fastened across an occupant’s body.
Precautions To Take When Using Center Airbags
When using center airbags, remember they are only effective when an accident occurs.
It is essential to take other safety precautions. Wear a seatbelt and observe the speed limit to reduce the chances of having an accident in the first place.
Also, occupants should make sure not to sit too close to the center airbag. Sit in the proper seating positions, maintaining some distance between you and the airbag.
Ensure that objects like purses, bags, or even groceries are placed in a secure area and not near the airbag.
These items can interfere with its deployment. They cause additional injury during an accident.
Be sure to secure children in the back seat properly. And make sure their feet are not touching any part of the airbag when it deploys.
Maintenance And Replacement
Regular maintenance and inspection of center airbags are essential for their optimal performance. This should be conducted at least once every three years or 36,000 miles, whichever comes first.
Here are some tips to keep in mind when inspecting and maintaining center airbags:
1. Inspect the airbag’s exterior for any signs of wear or damage.
2. Ensure that all mounting hardware is securely attached and undamaged.
