Adjustable support systems are provided for holding human arms in fixed or moving positions, and providing support for other portions of the body that may be subjected to strain. The support systems are configurable for use in a variety of postures including sitting, standing and crouching. Dynamic support components are incorporated into the system to counter forces on a user created by a user's posture or objects a user is lifting or working with. The pivoting joints can be compliant within a settable range of motion, and the torsional forces produced at the pivoting joints can be variable by use of an elastic element acting across the fixed and movable sides of the rotary joints. |
