ABSTRACT:
An inflatable seat cushion is positioned on a firm support on which a user is seated for assisting the user in rising from a seated position. The cushion is in the form of a ring-shaped inflatable tube having a front and rear area in which the front area is restricted during inflation with respect to the rear area. The ratio of inflation being between the rear and front areas is in the range of three to seven times greater. The inflatable cushion is inflated under the control of the user or attendant whereby the thighs of the user are supported and are elevated by the inflation of the front area of the cushion while the user's buttocks which is seated on the cushion is simultaneously elevated about 3-7 times higher than the user's thighs thereby raising the user slowly from a sitting to a standing position in front of the support in which the cushion is positioned. The cushion may be formed of two ring-shaped tubes which are inflated simultaneously but are bound together and restricted in inflation by a suitable cover or binding. The cushion may also be formed of a single tube which is tapered from front to rear which also may have a suitable restricting cover.
