Air Bag Folding
Country: United States

How do they put the air bag in the steering wheel of a car?
Airbags are carefully folded an exact way, so that when they
suddenly are inflated, they unfold without one part of the
bag getting in the way of the rest of it. Quite a bit of
research was needed to determine the best and most reliable
way to fold an airbag, so that it works every time.
This is rather like how parachutes are folded. If a parachute
is incorrectly folded, it will get caught up in itself when
opening, with disastrous consequences for the user. Well, it
is the same with an airbag. Great care must be taken to
ensure it is folded in the correct sequence, otherwise it may
fail to inflate properly, resulting serous injury to the
person behind it in a crash.
