When I recovered my 73 seats (1973, that is) there was a piece of spring
steel in the tube in the seat back that pressed on to the shaft on the head
restraint, presumably so it says where put. As I can recall no end-stop on
the shaft I can only assume that sufficient force will pull the whole thing
out, assuming you can move it at all. You may be able to slide a piece of
thin steel strip down between tube and shaft (can't remember whether front
or back) to help free it up.
(or if that URL doesn't work try )
