Do you mean the speed of impact (i.e. the speed the car was doing immediately prior to impact) or the speed at which the airbags themselves deploy from the steering wheel / dashboard?
In terms of impact speed, the airbags are designed to not deploy in an impact with a solid barrier at impact speeds of 14mph or less - this is the UK standard test for insurance repairablility for low-speed impact, and preventing the airbag from inflating in these type of impacts keeps insurance costs down.
However, the loads registered by the car will differ with different types of impacts, so the airbag may not deploy in a 20mph impact if you hit a softer object, or it may deploy if you hit a solid object at a lower speed, but only part of the car takes the impact (e.g if you hit a lamppost). If you hit an oncoming vehicle, then the speeds of both vehicles will affect the severity of the impact, and hence whether the airbag deploys.
The speed at which the face of airbag deploys from the steering wheel or dashboard can exceed 200mph.
Airbags are designed to fully inflate before the occupant hit them, and to deflate at a controlled rate as they hit them, hence softening the impact of the occupant with the car's interior.

It isn't about speed it is about how much force the impact is. There are sensors in the front of the vehicle. Upon impact if the force of the impact is great enough to trigger the sensor the airbags will deploy...Prior to the late 90s the airbags would deploy at 200 mph which would cause injuries to the crash victims. Now days they are delayed just enough not to cause injuries. Hope this helps you out.

if you're asking how fast do they go off then i have no idea, but if you're asking how fast do you have to be going in a crash for them to deploy then the answers is :- Airbag deployment is not dependant on speed, instead it is dependant on the movement of the person sat in the seat , if for example during a crash you stay upright in your seat the airbag should not deploy, if however you start to slide on you're seat (know as submarining) the airbag is deployed to hold you in the seat during the collision, hope this helps .
P.S. if you are not wearing your seat belt in a collision and the airbag deploys it'll pick you up and put you though the roof.

Speed is not relevent. Airbags deploy if you stop quickly enough.

speed of teh airbag is almost supersonic... unlike the astra...

The same as almost any other automobile w/SRS systems. As soon as the inertia switch see's an impact.

i should think the same speed as every other airbag...milliseconds

from what i've read could be 200 mph
