Abstract
The rotary adjustment mechanism adjusts the seat back of a vehicle seat. The mechanism includes a handle mounted for rotation with respect to the seat. The handle has an internal gear, and the internal gear drives a pair of pinion gears positioned within the internal gear. Each gear rotates a flexible shaft, and each shaft connects to a leadscrew. The leadscrew has a threaded end, which mates with a threaded nut connected one seat pivot. Shaft rotation rotates the leadscrew, which causes the threaded nut to move axially, which in turn, pivots the respective seat pivot.
