Abstract
A seat (10) includes a backrest portion (16) and a seat portion (14) for supporting a cushion (12). The backrest portion (16) includes a back frame (18) which supports an expansion bladder (28) for expanding and retracting to provide lumbar support. A longitudinal plate (34) is fixedly connected to the frame (18) at a first end (36) and placed over the bladder (28) to provide lumbar support in response to selective expansion of the bladder (28). A second end (38) of the plate (34) is slidably connected within a rotatable member (46). The rotatable member (46) allows bending of the second end (38) to provide thoracic support separate from the lumbar support.
