10 G is not sustained. 10 G max is not enough for airbag deployment in cars.

For a short time is nothing to talk about during emergency when it comes from the back (eyballs in) and you are protected from the whiplash.

Agreed, I've read you get about 4g peak deceleration going down stairs. But people seem to survive that process on a regular basis. So a temporary 10g is not a problem, and the effects of gravity loads on the human body are well studied and understood by military and aerospace organizations.
