Abstract
The seat has a cushion portion and a back portion connected thereto by a pivot. The back portion is rotated relative to the cushion portion about the pivot by a flexible threaded tube rotatably attached to the frame of the cushion portion and passing through a threaded member on the back portion. Rotation of the tube by means of a hand wheel, or an electric motor, drives the threaded member. The thread is selected to be self-locking.
