Put an explosive device under a cough cushion.

Hilarious.

Would have been even funnier if it had driven his spine up into his
brain pan or he hit his head on the edge of the table on the way down.

Freakin' really funny.

Assholes.

Oh, hell. The auto makers put that same exact terrible "explosive
device" right by the head and face of every driver......

I thought you were an engineer.

The crash sensor triggers an electrical impluse igniting a pellet of
sodium azide. The reaction generates nitrogen gas which fills a nylon
or polyamide bag at a velocity of 150 to 250 miles per hour. The
entire process occurs within 40 milliseconds at about 200 mph +/- 15.

In order for the airbag to cushion the head and torso with air for
maximum protection, the airbag must begin to deflate by the time the
body hits it. The very high internal pressures produce a surface as
hard as steel. The entire process occurs within 40 milliseconds from
inflation to deflation.

The deflation process is accomplished by completely opening the bottom
of the bag as the inflation process is proceeding.

The video in question shows the victim sitting on top of the bag which
launches him a good three feet straight up.

Straight up. *Hardly harmless.- Hide quoted text -

I full well understand how an airbag works. Because of the cushion,
I'm betting the acceleration wasn't that great. Also, given the body
weight of the individual, that would also dampen the rate of
acceleration. The airbag can expand up to that three feet that he was
launched. Therefore, it is a lot different that if something only
inflated 8 inches and slung him three feet into the air.

And to be precise, if you were to drop the person from that three feet
onto the couch cushion, that would be the same force of impact that
propelled him three feet.

The thing I noticed however was that he seemed to be holding his lower
back when he hit the floor.. I know an impact like that would screw my
back up for a while, especially if I wasn't sitting up straight, like
relaxing on a couch. I would be ****ed.
