[W126 Coupe] Seat Lock Problem

[Dick Spellman]

Dan,

They slide forward and then lift up at the front and continue pulling 
forward to release the tab at rear.

The front most side edges slide under a metal lip and the back end of 
the cover has a plastic tongue.

You need to find a way to gently tap the plastic cover so it slides 
forward.  Only needs to move perhaps 3/8 inch (8mm) or so to free it up.
