what is this

i think that is the space jockey suit but split open down the middle, and the space jockey sits in it and it closes. that is a far stretch but i think that looks like the head split open.

I read it as half of the SJ Bio meck mask (which most likley connect to the hose or trunk, when he is seated and the, marsk suit and chair close around him - see the open apeture of the chairs bottom) if you look at the Bald Bio mech Guy in the picture he hs a slightly drooping pointed face he will most likley resenble the Fossilised SJ we all know and love. Unfortuanlety I really think he will be the SJ and if you look to the left you will see one what looks to be an open cryo tube (there are what looks like 3 on the floor (a closed one near him) and slightly behind the chair). Yep my money is the big dude is SJ sans Bio suit/ chair molding and has just left the cryotube to the left (It looks open). Most likely thought dead in the chamber when David was looking at the starmap and then aweaked for his mission in the chair (if this is indeed the same room or perhaps a regular shaped room on the ships or facilities) shame like others I really wanted to see the really alien SJ's doing thier stuff but I guess not and Scott has gone with the much more believable humanoid race, makes sense with any techno species to be adaptable (not stuck in a chair with poor head movement - if that was his nosed permantley connected to his ribs) and stand up and engineer things but a shame all the same, still wanted the SJ to be Alien all on its own and in its own way more strange than the creature that killed it.
