An improved adjustable body supporting assembly which is distinguished by its capability to provide with a single power means the movement of a support and the additional movement of a pivoting second support portion in relation to the first such as the head serving upper back support portion by means of linkages, to base and the improved adjustable body supporting assembly which is distinguished by single power means moving the lower body supports from a horizontal to an upward slanted position of the leg support in combination with the aligned knee support, and of moving the leg support from its slanted elevated position through a horizontal position at an angle to the knee support to a position with the leg support pivoted downward for a regular sit-up position. A variation of the embodiment serving especially for persons with cardiac or vascular problems, has power driven separate sides, each composed of a leg and knee support, and can be adjusted for separate positioning or programmed movement simulating walking movements to facilitate the hearts activity. The invention is also providing for more compact adjustable assemblies, moving from a wall hugging sit-up and elevated position to a full length bed. The embodiments also include an improved mode of operating a built-in toilet. A further variation, serving for human activities is provided with three separate adjustable lower supports, to facilitate various positioning of two occupants. The enclosed description of the objects of the invention and the description of the preferred embodiments of the various improvements serve to illustrate and explain said embodiments, but are not stated as limitations of the invention as various other embodiments can be developed.

A variable body support assembly composed of pivotally connected supports and distinguished by a single mechanism or power means such as a fluid driven piston in a cylinder serving to move, the leg support member of the assembly both for the adjustment of said leg support in relation to a knee support, and for combined adjusting movements of both said leg supports and its connected knee support simultaneously in relation to other portions of the assembly and whereby the adjustable assembly accomplishes with a single mechanism to have the leg support moved by said mechanism from a position wherein the said leg support is pivoting downward from the knee support with the occupants legs downward to the floor, to a elevated position as continuation of the knee support, and wherein a movement by said mechanism elevates said leg support together with the knee support to an upward and slanted position, and wherein a movement of said mechanism causes said leg support to pivot downward together with the knee support until the knee support is restrained from further downward movement by means such as coming to rest on an assembly member, to facilitate positions such as sitting up, and whereby a variety of other positions can be achieved.
