Was quite funny! However that's surely a set-up? If airbags went of that easily then I'd have got through loads whilst shunting my boat around. Don't they operate on speed/kinetic sensors like seat belts do?

To answer the OP, NO! Years ago I managed to write off a SAAB 9000 Aero, and the only injury was burns on my wrists from the b____y airbag!

Whilst you brought up the subject Ian. I know someone who I used to work with who's wife was blinded and received burns from an Airbag failure.

I think it's genuine, the old lady has obviously been on the Iron Brew cos the speed of her handbag hitting the grill must've been at least 20mph

It's the deceleration that sets them off.

It might have been genuine 30 years ago but on a modern car....I don't think so. Airbag technology is such these days that the airbag computer gets info on speed of car, decelleration and what type of impact to decide what airbag should be deployed and when it should be deployed. I believe that many airbags won't activate under a certain speed as a safety measure. You wouldn't want it to destroy your dash just from a slow speed shunt? Also the airbag inflates much slower than one would expect.

Airbags systems of the last 30 yrs are deployed by a control unit that responds to a crash pulse signature - unique to every model of car - received these days from one sensor but up to five in earliest times. The deployment is a function of deceleration AND time. A simple blow from an old lady and her handbag is neither strong enough nor long enough.

Typically, air bags never deploy at speeds of less than 19mph, the speed below which no serious injury would occur to an unbelted occupant.

The whole airbag deployment event is over in around 60ms - if you're going to get hurt it will be in this time window. When the 60ms starts is a function of when the airbag is deployed by the control unit - earlier in a high speed event, later in a lower speed event.

I think that I'm right in saying that for a long time manufacturers of cars have been looking at inventing/developing an intelligent explosive charge, one that gives variable inflation rates. They have to date been unable to find anything that can react quick enough in the event of an accident. Come on guys, get your thinking caps on!

Airbags deploy at something like 200-300mph. That guy would be picking the lenses out of his head, not simply removing his shades.

And not a chance that hitting a bumper will set it off.

As I recall, it was an ad for something but I don't remember what (wasn't it on this site a few months back? )
