Mid century reclining type club chair

I'm new to this community and need help in any info regarding this type of chair! It has a mechanism that causes the seat to move forward and back similar to a theater seat. It had straps that were connected underneath and all the way up the back but are no longer there or connected. Love the lines of the two we have, just have no clue as to how to fix them and bring them back to the correct operating status. Can't find another style similar. Any help would be appreciated.
