Abstract
An adjustment mechanism for use with a chair. The adjustment mechanism is for use on a chair that has a base assembly with an extending pedestal, a seat, a chassis, and a back. Specifically the adjustment mechanism is for use on a chair that utilizes a J-back bar that couples the chassis to the back. The J-back adjustment mechanism allows the angle of the J-back bar and thus, the back to be changed throughout a range of motion. The J-back adjustment assembly includes a casing and an adjustment portion, wherein rotation of the adjustment portion changes the inclination of the J-back bar and, thus, the back with respect to the seat.
