Body support cushioning system
Abstract
Abstract A CUSHION FOR UNIFORMLY DISTRIBUTING SUPPORT OF AN INVALID COMPRISING A LIQUID CONTAINER OF FLEXIBLE SHEET MATERIAL WHICH IS IMPERVIOUS TO THE FLUID, AND MEANS TO ELEVATE SIDE PORTIONS OF THE CONTAINER TO FORM A LOOSE UPPER SURFACE WHICH CAN CONFORM TO THE SUPPORTED BODY PORTIONS OF THE INVALID AND SUPPORT THOSE PORTIONS AS INFLOTATION. A SUPPORT STRUCTURE FOR THE LIQUID CONTAINER IS ARRANGED TO CONTROL THE POSITION OF THE SIDE PORTIONS OF THE CONTAINER AND, FOR A CONSTANT VOLUME OF LIQUID THEREIN, ADJUST THE DEPTH AND ENABLE BODIES OF VARYING WEIGHT TO BE FLOATED FREE OF THE UNDERLYING SUPPORT SURFACE. RESTRAINING MEANS ARE PROVIDED FOR THE CONTAINER TO MAINTAIN ITS ORIENTATION ON THE SUPPORT SURFACE DURING MANIPULATIONS OF THE CONTAINER AND INVALID. A CUSHIONING PAD ACCOMMODATES THE CONTAINER RESTRAINING MEANS AND CONTAINER POSITIONING MEANS WHILE MINIMIZING DISCOMFORT TO THE USER.
