Abstract
A seat (10) including a backrest portion (16) with seat back support (24) providing selective lumbar support to a user. The seat back support (24) includes a pair of clam-shell shaped air bladders (28, 30) with their movable, expanding ends (36, 38) facing one another. Divider members (42, 44) split each of the bladders (28, 30) into separate side-by-side air sections to maintain the clam-shell shape of the bladders (28, 30) preventing bowing in the center of the seat back (14). The bladders (28, 30) support and move a flexible plate (70) connected thereover to provide selective contoured adjustment to the lumbar region of a user.
