Abstract
An inflatable lumbar support system that includes a plurality of thermoplastic layers sealed together to form at least two laterally spaced bladders. A resiliently flexible face panel is disposed between the back of the user and the inflatable chambers. The panel is composed of form stable outer portions overlying the laterally spaced bladders and a medial portion therebetween of substantially greater yieldability than the outer portions of the panel. The inflatable lumbar support system is incorporated within a chair having a one-piece shell with a backrest that is cantilevered from the top of the backrest. The lumbar support system is carried by a mounting plate that includes a pair of mounting hooks that attach to and can slide vertically along the side edge of the cantilevered portion of the backrest. The lumbar support system can be slid vertically along the cantilevered backrest and can be inflated and deflated by a person setting in the chair.
