So you want to fit an airbag?
After seeing this video I would think twice

the idea is that the airbag fully inflates before you hit it, thats why it needs to inflate so fast. if it inflated slowly you would hit it while it
is still going off.
there have been a few cases where they have hurt people, one where a child was killed in a crash at less than 10mph, the child was leaning forward
when it went off.
seatbelts sometimes causes a broken sternum, i will always wear one.

They are worse than that!!!
There have been cases of kids in rear facing seats mounted on front passenger seat who have been decapitated by them.
A friend runs a Ford shop with his brother and he told us that the "official" way to make seat was to place it on floor, pile tyres over
it, leave room and set off!

if you have a piercing on your face they can burst the bag which will set all the burning gas' into your face i would rather stay with the
seat belt

burst!!

The air bags are made from 2mm kevlar, I doubt you could bust one with a pick axe. The bags are vented with 25mm holes so it is the pure gas pressure
that holds it open, and they deflate instantly.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Thats why an air-bag is technically classed as a Class1 explosive device and when delivered to or by a dealers or aftermarket repair shop they legally
be delivered in an armoured vehicle with an escort.

I was in an accident once and i my air bag went off, iwasnt wearing a seat belt at the time. It was a glancing blow off the side of another car so
m head wasnt near the bag. Scary shit. From that day ive always worn a seatbelt. The amount of dust and smoke that fills the car is unbelievable.
Sore throat for days.
If u got stuck in the car with more than one bag and the windows were shut the dust would seriously get in your lungs!!

i found it hard to belive till i saw pictures of it which made me think it happened but still
didn't understand how

dunno
it all will depend on the g's during the impact...
but if the g's are high i surely bet you that with the 3point harness (1 band of 50mm)
you don't want put you body weigt x g's on it...
an airbag isn't an pleasure...
an broken nos either..
broken ribs/lungs either..
i choose airbag...
Tks
don't think airbags are explosive number one....
because they need an good amount of current to go off...
its not like TNT with an small spark it goes..
how much force would it have if you would mount one on the ground.. and put your own weight on it??

My wife used to work in A&E and they are seeing an increase in the injuries to children by airbags. The problem is people don't understand
the danger and let children under 4' tall travel in the front seat. when the airbag goes off it is positioned to protect an adult and the
explosive charge can end up blinding the child !

The video is not a good representation of an air bag going off - it looks like they set it so that the bag would inflate downwards, throwing the more
massive casing upwards.
If the bag had been facing upwards it would have just inflated (like the current Boots ads!)

Thats why the oem's spend time calibrating them so they don't go off when they shouldn't. I've driven into large kerbs and
towed cars through ditches to test this!

As opposed to not having the airbag in the head on ? I will take the broken nose and slight burns instead of fractured skull ect ect ect.- But I
dont have airbags in any of my cars- all too old.

I think we are maybe missing the point of airbags! They are meant to be used in conjunction with seatbelts. The seatbelt protecting the
driver/passenger from major injuries in the event of a sudden stop accident. The air bag is a "secondary restraint system" (SRS) that
should only deploy in the event of a serious accident. In this cirtcumstance minor injuries cased by the airbag are of little concern compared to the
more serious internal injuries that could be caused by making high inertia impact with less yeilding components of the car. I think that the idea of
fitting airbags to kit cars is an area that could benefit from some serious research particularly in the area of side impact protection.
Experience is what you get when you don't get what you want!!!

I was once first on the scene when a BMW had gone straight into a wall.
The lass driving wasn't wearing a seatbelt, and the car was too old for airbags.
There were bits of her forehead on the steering wheel and windscreen where it has smaked her head and her face was split right open from the crown of
her head down to her chin.
Guess that's why I have a phobia for blood and all things grusome like that now.
Fortunately, a police van came round the corner almost immediately after I had run over to her car and opened her door.
Airbag and seatbelt every time for me and no one rides in my car without a belt on.

When i was at Nissan i watched an airbag test. When you watch it live, it all happens so fast. But they film it using a very high speed camera, when
you watch it on this you can see the flame coming out of the explosive, doesnt look like the sort of thing you want going off in your face! Also they
made us stand behind a screen while it was going off!
Still i would rather have a few burns than my face split in 2.

* The air bag's inflation system reacts sodium azide (NaN3) with potassium nitrate (KNO3) to produce nitrogen gas. Hot blasts of the nitrogen
inflate the air bag.
The inflation system is not unlike a solid rocket booster. The air bag system ignites a solid propellant, which burns extremely rapidly to create a
large volume of gas to inflate the bag. The bag then literally bursts from its storage site at up to 200 mph (322 kph) -- faster than the blink of an
eye! A second later, the gas quickly dissipates through tiny holes in the bag, thus deflating the bag so you can move.
Even though the whole process happens in only one-twenty-fifth of a second, the additional time is enough to help prevent serious injury. The powdery
substance released from the air bag, by the way, is regular cornstarch or talcum powder, which is used by the air bag manufacturers to keep the bags
pliable and lubricated while they're in storage.
Experience is what you get when you don't get what you want!!!
