Xcitation,
I was very surprised myself to read the BEA report's section on cockpit PF and PNF seats - section 1.12.4.2.1.3. I was also dissappointed, as it has made no special reference to the pilots, just the seats. One can only infer the pilots state based on the generic comment in Section 1.13. which has only one sentence on the new found bodies referring to the previous analysis.
That being said, I've thought about the problem of him flying unbuckled, and the rest of what you've mentioned.
With the risk of repeating of what was already said, that means that either the impact, the shock unbuckled him, or him being alive and unbuckle himself. If it were the latter, then the Section 1.13 would not apply, which invalidates the latter. If it were the first, the BEA investigation would have found some evidence, but that is not mentioned at all.
This leaves us open to speculation.....

A word for word translation of the BEA Report text I have referred:
1.13 Renseignemants medicaux et pathologiques
L'examen des corps remontes lors de la phase 5 confirme les observations consignees dans le rapport d'etape nr 2.

I find it very unlikely that PF would not be strapped in whilst entering turbulence, at the onset of AP disconnnect, approaching impact. Surely the capt or FO would say something? I don't think that FDR capture a seat pressure sensor and belt activity.
