Abstract
A lumbar support system for a seat backrest having a fixed frame includes a lumbar support coupled to the fixed frame that is movable from a first position to a second position and a motor for moving the lumbar support. A threaded member is operatively associated with the motor such that the motor rotates the threaded member about an axis. A traveling member is operatively associated with the threaded member such that rotation of the threaded member translates the traveling member along the threaded member. The system further includes a flexible cable having a first end and a second end. The first end is coupled to the traveling member for movement therewith and the second end is coupled to the fixed frame such that translation of the traveling member in response to rotation of the threaded member moves the lumbar support element from the first position to the second position.
