Though not appearing in the patent drawings, most people not in a SWAT team would likely baulk at the idea of simply hanging around in a four-bar cage at a great height, and so some form of restraint looks essential ~ and it might as well be combined with a form of flight-deck for any time you need to do the flying. I've actually got templates somewhere in the workshop that literally describe my own beer-gut, and it did prove to be a practical proposition to practically 'wear' a personal airframe. Again these are likely to be bespoke items for maximum comfort... "Suits you, Sir!".
What I've done here is rather than fashion a generic void in the deck, I've been able to sketch around the mannekin's midriff because it comes in two halves. The elbows do coincide however with the waist a little further upwards, though I figured if the deck fits around the hips like this, then it's likely to so beyond. Incidentally when we look at centre of gravity issues, a Google search suggests that your own centre of gravity does coincide with a point that coincides more or less with your belt-buckle. Figured it'd be higher than that, especially with a brain my size...
