It seems like it blowing up like a balloon would reduce the impact, but make you more likely to tumble.
Prepare to be bored!!!
After retiring in 2007 after 34 years as a Fireman, ( no pandering to the PC brigade here!!!), I still go abroad to work for the Fire Service College as an Instructor. One of areas I instruct in is Road Traffic Collisions, extrication of people etc., etc.
Now, I don't know for definite if bike jacket air bags would be the same or even similar to cars but car air bags kind of deflate as they inflate if that makes any sense, they are designed so they don't become solid, if they did they would cause injury to the occupants, therefore defeating their purpose, I'd imagine the bike ones would be designed in a similar way.
Just to make you aware, undeployed ones, can still operate up to about 20-30 mins after an impact, so if you come across and RTC with undeployed bags try not and stand in the line of fire, I have a cracking video , from Florida I think, of F/f's in and about a car after a crash and an undeployed airbag suddenly goes off .......oops!!..ouch!!!... not the cleverest place to be I can assure you!
To Hobat, as to the speed of deployment, unbelievably fast , thousandth's of a second, if you just toppled over without coming off your bike I wouldn't think, as you say it would operate, but if leaving the bike I've no doubt it would deploy before you hit the deck.
Did I ever tell you when I was in Iran last year I turned round just in time to see an Iranian f/m about to cut the 'B' post , (which contains an airbag and gas canister), with hydraulic cutters............????????????? , he didn't realise a Scotsman knew so many swear words and could put them in the one sentence!!
