ABSTRACT:
A combination chair and seat pivoting mechanism includes a frame and a seat section pivotally connected to a front end of the frame. The seat section is pivotal along a fulcrum axis defined along a front end thereof. The front end remains contiguously abutted with the frame during pivoting motions. Pulleys are connected to spaced portions of the frame and are registered along a single plane. A weight member is coupled to the pulleys and positioned subjacent to the seat section. A cable is tethered to the frame and the weight member. A pneumatic piston has a stationary portion coupled to the frame, and a linear piston coupled to the seat section. The pneumatic piston and weight member cooperate in tandem for resisting an operating force directed on the seat section during sitting and standing procedures.
