Well, I had a minute between Zoom calls ...
There are two cables involved. The first runs from the passenger's right shoulder to the passenger's right hip. All this cable does is initiate the seat 'tilt'. When the seat tilts, it pulls on the second cable, which initiates the tumble. This second cable runs from the passenger's left hip, under the seat springs, to a mounting point right next to that "paddle lever", which as you probably know can be used to manually trigger the fold-and-tumble action.
Pics below.
First cable initiates 'tilt' feature only. Can be triggered by pulling on ribbon or lifting the lower lever. | Second cable attaches here. It's missing in this pic, but you can see the black sheath, and also the mounting point / hole that pivots when the seat tilts forward. | Second cable runs under the springs, along the left side of the seat. It terminates at a mounting point right by the paddle-lever. | Closer pic of where the second cable's sheath terminates at a mounting point, with the nearby hole for the cable to connect to. Just under that is the black paddle-lever. |
