Air bag device effectiveness

[Checkswrecks]

Been at the SAE World Congress / convention this week and got to sit in on some motorcycle safety seminars. One was about data regarding air bag vests and had not realized how much positive affect they had on accident outcomes. This included data from a study of accident data, crash dummies and cadavers. (PMHS or post mortem human subjects, typically did in their 80s)

And just to get the old assumption out of the way, “other drivers” is not even close to being a major player in accident causality. I wasn’t taking notes but more than half are roadway departures and loss of control was also large. Overall third had alcohol out other impairment involved. The data that does say another vehicle was involved does not say which was at fault but it was striking how many photos were head on collisions showing motorcycles in the left lane of right hand curves.

Getting back to the subject, simple frontal collisions (iirc) at 40 kph (24 mph) reduced broken ribs (they puncture internal organs) from 97% to 70%.
Neck injuries were reduced by larger numbers.

Really kicking myself for not shooting photos of slides or taking notes but below is an older study with similar findings. https://www.ircobi.org/wordpress/downloads/irc19/pdf-files/76.pdf

Dirt Dad and I bought cable operated Helite inflatable vests probably five or six years ago and I’ve had to repack mine twice. Toward the end of last season I’d gotten lazy but after this conference I’m a believer again.

I have been looking at these for a couple of years. I am leaning towards Klim's air vest but every time I look, they are out of stock.

While good that Klim, alpinestar, and Dianese open faster (20 vs 100 ms) they also require a subscription with a monthly or annual fee and need to be sent in for repacking if they open.

I have bought mine 3-4 years ago after asking some members here. (Like it or not somethings in the USA are years ahead the rest of the world...)
Mine is manufactured by an Italian company, motoairbag, and at the time it was the one with the biggest litres once opened.
I chose mechanical over gps because I am mostly riding on mountain where there is not signal coming ...

I'm not sure I quite understand these. I was looking at them and had thought that they went over a jacket. It looks like they go under the jacket. And the one I was looking at only went up to 2XL. I'm a 3-4XL depending on where stuff is made. Or does one need to have one for under and a jacket version?

Kinda like a box of chocolates, they come in a wide variety. The vests to wear outside your jacket are the least expensive and well proven. There are manufacturers who make the bladder system as part of the jacket, and I believe some can be worn inside of outer gear.

They can fit fairly loose so my guess is that you’d do fine in the Helite XL-L. It’s also one of those things where exact fit is not really critical. Have any motorcycle gear shops to try one at? A Cycle Gear near us has a demonstrator.

Our dealerships now are lucky to have helmets and tires, nevermind these.
