Controlling device for controlling sitting position e.g. for prevention of spine tendon-muscular disorders, has rigid unit movable in center of gravity around joint that is located adjacent to and perpendicular to spinal axis of user

摘要

The device has a central base (5) connected to two side knee supports (7) by short connection elements (6) to form a rigid unit (4). The rigid unit is symmetrical and movable in a center of gravity around a joint (3). The joint is connected to a base (1) by a frame (2) and located adjacent to and perpendicular to a spinal axis of a user. A fixed handle is located in front of the central base and connected to the base by a rigid stem. The connection elements retain feet supports, and the knee supports are placed in an identical and symmetrical manner.
