Abstract: In an orthotic walker, mechanism is provided to bias alternate motion of a user's legs. The mechanism may be a reciprocating bar at hip level, or at least one strap ends of which are attached to leg braces and the bight passing round a fixed frame member. A stirrup mechanism may be pivoted at an "ankle joint" and the pivotal motion may be limited to avoid toe down position. The stirrup may have a clamp for a shoe. Brake mechanism may be movable between operative and inoperative positions. In the operative position rearward rolling is disallowed while forward motion is allowed.

Abstract: The present invention relates to a body supporting network suitable for use with a load supporting system. The network includes at least first and second pluralities of elongate support members securable with the system for supporting a load. The first and second support members respectively extend in first and second directions to provide potential load receiving intersections where the first support members cross the second support members. The network includes adjustment means to vary network pressure response at each intersection and to permit changes in network contour. The network includes interconnecting means for connecting the elongate members at the intersections to maintain network integrity when the network is subjected to the load.
