ABSTRACT:
A chair back has a user-positionable lumbar support plate, movable vertically along the back to position the support in an area between a padding panel and a backpan of the chair back. The lumbar support plate is mounted on a pin-and-slot track, and protrudes forwardly to bear against the padding panel to provide a protrusion or relatively harder section in the chair back at the chosen height. Cable-in-conduit control lines are attached to the lumbar plate and to a manual control such as a pivoting handle on the chair seat, in a closed loop whereby the handle positively positions the lumbar plate in a push-pull arrangement. A low friction sheet material is disposed between the lumbar plate and the padding panel for free sliding, and can be attached to the backpan above the range of travel of the lumbar plate. A series of spaced stops are associated with the control handle for fixing the vertical position of the lumbar plate.
