ABSTRACT:
A bed comprises an inflatable mattress supported on a platform of articulable links by a support system mounted on a base frame. A connector assembly is used to couple the cells to the platform, to adjacent cells, and to tubes connected to other cells. The mattress includes lateral cushions or cells that have a general triangular shape with larger upper cells forming a patient support surface and smaller base cells laterally supporting the upper cells. The upper cells may be elevated at the ends to form a broad U or V shape. Alternative embodiments include shorter base and upper cells with a box-shaped restraining cell on each end that extends above the upper cells. Modified upper cells have end pouches that store separate restraint cells when deflated, and provide inflation pressure when removed by a fixed connecting tube. The restraint cells are positionable along the host upper cell and anchor to catches mounted on the adjacent base cells.
