With the third generation of D-Air systems, Dainese have developed their most effective and accessible airbag to date. So what makes them tick?

The best manufacturers understand that the most important aspect to a motorcycle garment is its protective properties, and they don't get more effective than an airbag system. Since 1993, Italian brand Dainese have made consistent strides to evolve their patented airbag systems, the Dainese D-Air, to higher standards of safety, improved ergonomics and terms of use, and the most precise activation to one-thousandth of a second.

Dainese D-air systems are some of the most proven in the motorcycle industry with, as of writing, 12 years of MotoGP experience, thousands of analysed tests and deployments, and more than a dozen patents on just the airbag alone. Now in their third generation, Dainese has developed a full range of products specific for both track and road use, with reduced overall weight and a higher level of active and passive protection, and for the first time, various models specific for men AND women.

So what makes these airbags tick?

So, what is "D-Air"?

The D-Air system consists of a special piece of personal protective equipment (PPE) that uses an inflatable protector. Essentially, it's an airbag specifically designed for motorcyclists.

In a car, the simple concept of the airbag is an inflated cushion fitted between its occupants and the surface of impact and is designed to greatly reduce the risk of trauma and injury, as the resulting energy from the impact is absorbed by the cushion and deceleration is smoother.

Whereas a car collision would cause occupants to hit violently against the inside of the cabin, typically against the steering wheel, dashboard or doors, strapping an airbag to a motorcycle isn't the most effective method of protection, as a rider could fall in any direction during an impact, rendering the inflated bag strapped to the bike useless. Therefore in translation, the airbag cushion must be applied directly to the rider's body.

Lino Dainese understood this back when he developed the first concepts of wearable airbag technology in 1993. These early prototypes adopted airbag technology seen in cars at the time, with the airbag on the outside of the suit. From the outset, Dainese's aim was to create an airbag for motorcycle riders that could detect an impact and activate a three-dimensional airbag that covered the most critical parts of the human body.

Throughout the years, Dainese and his team were able to examine a large pool of data on motorcycle accidents that allowed them to understand which parts of the body were more susceptible to trauma in a number of different situations. Their research was pivotal to understanding than an airbag system must offer the best passive safety, while also maintaining the highest level of active safety. Their modern designs were created based on this concept,

Nowadays, contemporary D-Air systems see the airbag ingrained into the internal fibres of the rider's suit, as before they were an internal vest separate from the garment. There are also two different designs depending on how the D-Air is to be used: D-Air Racing designed for track-day use and racing, and D-Air Road, intended for touring and adventure riding.

These systems are built up of three elements that make them so effective: the special inflatable bag and the microfilaments within it, the electronic control unit that measures and detects the rider's actions, and the algorithm that calculates deployment.


What is the Airbag made of?

The core element of the D-Air is the special inflatable bag that protects the rider's body. This cushion effectively absorbs and distributes the energy of an impact in the event of an accident. This bag features a specific shape designed to cover the anatomical areas that need the most protection in a collision and is different in D-Air Racing and D-Air Road garments to best compliment the garment's use.

Inside the cushion are Microfilaments, a Dainese invention that differs from any design in an airbag system on the market. These innovative microfilaments, when in use, create real armour made of air that maintains thickness and an area of impact that is constant across the whole area of the body protected by the bag. The internal pressure inside the bag remains the same at each point, achieving a homogenous level of protection across the entire air armour.

The combination of high pressure and the microfilaments prevents air from escaping to other parts of the airbag when weight is applied. This prevents any irregular expansion or change to the shape of the bag and provides a consistent, high-level of pressure at any point in the bag.


How does the airbag inflate?

The D-Air system operates on a combined action of a number of mechanisms, from the airbag, a gas generator, sensors built into the suit, and the built-in software.

Inside the airbag is a built-in canister filled with highly-compressed gas that when activated, immediately inflates as the gas expands directly inside the bag. This cold gas generator is operable via an electronic control unit that consists of 6 sensors: 3 accelerometers and 3 gyroscopes that work to recognize the rider's movements, and a GPS that allows the system to detect and accurately measure the rider's actual speed. This is powered by a small, lightweight lithium battery that can be recharged via a USB port and a micro USB cable.

This control unit works in tandem with the system's internal algorithm, built up of a complex combination of instructions, controls and calculations, analysing the information provided by the various sensors up to one thousand times per second and decides whether to activate the airbag.

With 18 years of development and data analysis, and 2500 activations during testing, races and road use, the software built into the D-Air is so intelligent and effective, the airbag is only deployed only when precisely necessary.


What is the difference between D-Air racing and D-Air road?

During development in each generation of airbag systems, Dainese adopts a single philosophy: to expand diversify in their range to protect what must be protected, as required by the context.

Essentially, Dainese develops each product to fit around its intended use. In the context of D-Air, the needs of an adventure and touring rider are different to the needs of a racing and track-day rider, and so how the D-Air System works is different to cater for these needs.

The key differences in the two systems are the shape and size of the airbag, and deployment algorithm. This is because they are two different fields of application when taking into account speed, terrain, and impact, so as to offer the most protection to the human body as possible. The microfilaments inside D-Air Racing and Road garments also vary in length, so as to maintain their thickness during an impact on different surfaces.

How effective is the Dainese D-Air system?

Every D-Air product is improved through experience, research and testing, with numerous advancements in technology made in each iteration of their airbag systems improving upon the last since their introduction to the commercial market in 2012.

Dainese claim their airbag systems are so effective, that they work 10 times better than a traditional protector. The effectiveness of a traditional protector derives from its ability to absorb the energy that results from an impact. The more energy absorbed by the protector, the less energy the rider's body receives. When comparing the energy absorbed by a D-Air airbag to a Level 1 chest protector, the amount of energy is reduced by 86%

What is new about the D-Air 3rd Generation?

Now in their third generation, the D-Air airbag is now fully integrated into the garment rather than in an internal vest separate from the garment. The total weight of the airbag system is 37% lighter when compared to their previous version, which makes for more comfortable wear and ergonomics.

Dainese have developed motorcycle airbag tech for both racing and road purposes, as well as of broadened themselves out of the motorcycle industry with products specifically for skiing, developing various models of jackets both for men and for the first time, women.

How do I reset the D-Air system?

In previous generations, the procedure to reset after deployment meant the garment had to be sent back to Dainese for the airbag to be replaced, and for a general check-up of its functions.

For the third generation procedure, the construction of D-Air Road garments has been overhauled to allow for easier reset of the airbag. All you need do is take the jacket back to us, Infinity Motorcycles, where we can replace the airbag after deployment using a spare parts kit sent by Dainese.

For D-Air Racing garments, these still need to be sent back to the manufacturer in order to reset the airbag. This is because the stress caused by the fall on the track, as well as the damage to the suits, only Dainese laboratories are capable of fully resetting the system's functionalities and restoring to maximum efficiency.


How to register the D-Air jacket/suit

Before you take home the D-Air jacket or suit you've just purchased, you will be required to register the product. This is so if you're involved in an accident, or if there is any damage to the jacket/suit or circuitry, you can send your garment back to Dainese to have it repaired.

You shouldn't need to worry about how though - this is carried out by our Infinity staff, and they only need your email, address, and contact number before letting you take your purchase home, or before dispatching your item if you buy online.
