Airbag deployment in a ZT

2750 HP · 9th March 2017, 18:52

Good evening: has anyone any idea please as to what speed a ZT airbag will deploy at?

Regards
Steve

It's not speed the airbag deploys, it's the sudden stop

Acceleration, which is a function of speed with time, to be accurate.

And for any pedants out there, yes, you have acceleration in negative figures.

To be pedantic is it not deacceleration that triggers the airbag? Acceleration will not trigger it.

I thought its electric impulse that deploy airbags

If someone crashes into the side of the car, is that acceleration or deceleration? I would say acceleration. And I'm sure the airbags would go off...

This is becoming a very funny thread...

But I think we may be losing sight of the OPs intended question, which I feel is asking for the deployment speed of the actual bag (correct me if I'm wrong - I probably am

) ?

A quick Google is saying at anything up to 200mph.

Can we clarify here please. A change in speed (mph, m/s, whatever) is an acceleration (mph/h, m/s/s). Deceleration is an acceleration, just 'negative' loool, oxymoron or no. I believe an accelerometer is used to initially trigger firing of the airbags. So yes, if struck whilst at a stand still, from the right direction (the accelerometers are direction sensitive) then the air bags may well be deployed.

Reminds me of that great TV advert when the chap is exhausted driving, looking for a comfortable way to get some shut eye, hits a tree a couple of times to get his front airbag out, and a nice comfortable pillow !!!

Oh, that contribution. Look the 'rocket scientists' out there might find it useful to speak in terms of negative acceleration, but that doesn't make it 'correct' in the English language.

Also very inefficient, so much easier to say or write deceleration than negative acceleration - just look at the syllable and letter count.
