In reply to jimtitt:
Ok, I read the "description"....
"Part of a contingency to hoist astronauts from the capsule that wasn't needed. The orange straps aren't criss crossed slings around the back, they're independent sewn terminations that are integral to the suit. Bright orange webbing indicates its a structural hardpoint on the suit that can support the entire weight of the person inside. Using the 2 bottom straps makes a sit harness for a conscious person, using the top 2 is a full body harness lift from the shoulders to get a floppy unconscious person out of the capsule, and there are additional straps not pictured in a small pocket near the wrists that you could lift someone in an arms up position from the sleeves to get someone out of a hole too small for their shoulders. Quick draws are some prerigging that lets you quickly choose sit harness or shoulder harness by detaching 1 side."
The above is one guys opinion on a climbing forum. Perhaps he's right but they look awfully tight to be able to simply detach from an unconscious person.
