I wonder if that's what Dainese does at their corporate team spirit days.  Roll Eyes

They all must get together around a table with donuts and coffee and take turns dumping the bike and having a little roll on the tarmac followed by a group hug.

How does the airbag know when to inflate?  I don't see a lanyard or anything and I paused the video where it inflates.  He's still got both hands on the handlebars so he hasn't left the bike yet.  Are there impact sensors on the side of the suit or something?  What happens if some close racing happens and you bang into another rider?  Do you puff up while still on the bike?

Listening to those two guys talk made me hungry..... Grin

BTW - this concept had been tried in the '70s but was shelved due to a cut in government funding:

I didn't read it, what does it say? It opens when someone pinches a fresh one in their shorts?




I tried listening to Valentino and the D-Tech guys explain it. It was kind of hard to hear but they said it goes off when there is a violent change in acceleration. The accelerometers are tuned to respond in situations where you'd need it and not when you don't need it. Vale is asking if it goes off when you wave really fast. They said no. That video showed a suit with internal airbags. Pretty dang cool  waytogo

Rider and track safety have improved over the years, and now manufacturers are working on airbags that prevent head and neck injuries. Spidi introduced an airbag for riders in 1999, and Alpinestars and Dainese are working on their own airbag systems. The Spidi airbag is worn over a jacket or leathers, and the Alpinestars and Dainese airbags are incorporated into racing leathers.

All three of the manufacturers use an airbag that inflates around the rider's head and neck. The Spidi system is activated by a cord that is attached to the handlebars. When a rider crashes and is thrown from the bike the cord is pulled and the bags inflate. The system has been criticized because it will not inflate if the rider isn't thrown from the bike and because the system will inflate if a rider forgets about the cord when they are getting off the bike.

The Alpinestars and Dainese systems use gyroscopes and motion sensors to detect crashes and inflate the airbags. Alpinestars Advanced Safety Technology incorporates the sensors into a rider mounted telemetry system that they have been using for several years. That system includes acceleration sensors, a central logging unit, two GPS units, an inertial motion unit and a display board. Both companies are still evaluating the rider data they've accumulated, and are perfecting their systems to insure that the airbags "inflate predictably in the right circumstances".

Dainese has been developing their D-air® Racing airbag with Grand Prix riders, and had their first deployment of an airbag under race conditions at Valencia in 2007. In the years since they first started to develop the system they have reduced the volume of the sack, redistributed protective areas, increased the system's inflation pressure and programmed the airbag to deflate after 10 seconds. The latest version of the airbag is contained inside the suit so when the airbag is deployed the suit expands.

next it will be Bluetooth connected to the bike's telemetry controls and computer and when the bike reads something(s) abnormal or outside of normal logged data from practise and other logged info they collect and and program and save, then the airbag will deploy.

I was wondering what the little bracket under the exhaust on the left side of the bike was for and then I realized -- it must be to lift the rear wheel & make sure the bike actually lowsides in a fairly controlled manner instead of losing the front or highsiding. Would have been kind of embarrassing had he crashed it before he got into camera range...
