Alfred,
This is fairly straightforward. First remove the recline adjusting knob, it has one keeper screw you can access by carefully prying off the plastic center insert. All of the other hardware is hidden behind the chrome covers. These covers are held on by 4 (I think) tabs that are crimped around the L-shaped brackets. Be very careful in opening these tabs, I use a long thin screwdriver to "unbend" them from the inside face of the bracket. Just be careful as the tabs can break off. You can actually just unbend the ones on the lower section of the L and then pop/slide the chrome off by moving it upwards. Once the chrome is off you will see the other screws that need to be removed.
Hope that helps, let us know how the recovering works out.
