[Iron Man] How come Tony Stark doesn't break his bones while wearing that suit?

He's a normal human being so far as I know and that suit moves in quite inhuman speed and absorbs quite a lot of damage.

The suit is rigid, it absorbs the force of impacts and distributes them around its shell, just like a medieval suit of plate armour would distribute the force of a sword blow to a limb without breaking that limb's bone. This doesn't explain why the G forces he experiences don't liquefy his internal organs, but not breaking his bones is exactly what you'd expect from a suit of titanium-gold alloy.
