Didn't you see the O2 canister in the back of the pilot seat in the video?
Assuming it wasn't moved prior to taxi and takeoff, the canister looked to
me like it was uncomfortably wedged up against the pilot's seat and
certainly would have prevented the seat from moving backwards.

It also may have prevented the seat from being locked in place OR
dislodged it. Then if that gurney and O2 bottle moved away goes the
seat.

It can happen, I've had jumpers move my seat for me...quite exciting.

I was thinking a seat slip also.
