Abstract
A seat assembly having a seat frame arranged to support a cushion, a rotatable armrest, a threaded receiver mounted to either the seat frame or the armrest, a translation shaft coupled with the other of the seat frame or the armrest which includes a thread disposed on the outside surface of the shaft arranged to matingly engage with the threaded receiver. Rotation of the armrest relative to the seat frame causes the armrest to translate toward or away from the seat frame as the threads of the translation shaft engage with the threaded receiver.
