Ok here goes, and with all things techie a few phots have gone missing so please ask if it seems there's a bit missing, and the wife will confirm there is a bit missing.
I am using flickr now phuckbucket want to charge, I don't find it as easy and always seem to end up with a bit of photo code on the thread, but oh well.
I'm assuming the seat is out on the dining room table or kitchen side
Bit that got me before I realised was the plastic covers and the plastic pins, pushed out with a long screwdriver from behind, and gently removed with long nose.
Little spring clips on the hinge pins pull off
Found I needed to remove the seat catch buffers
