Abstract: A weight stack frame for supporting the weight stack of an exercise machine is designed for positioning alongside a seat and exercise device. The frame has spaced upper and lower struts, and front and rear upright struts extending between the front ends and the rear ends, respectively, of the upper and lower struts to form an enclosed frame. Each upright strut is inclined forwardly at a predetermined angle, and the frame can have a load transfer cam mounted either on the front or rear strut for transferring load to the exercise device alongside the frame.
Abstract: An adjustment apparatus for adjusting the position of a back pad or seat pad of a seat has an inner tube with a series of spaced openings for securing at one end to the back or seat pad, and an outer tube telescopically engaged over the inner tube and secured to a support frame of the seat. The outer tube has a pinning opening for alignment with a selected one of the openings in the inner tube. A lever is pivotally secured on a pivot bracket on the outer tube for rotation about a pivot axis with a first end portion of the lever projecting over the pinning hole, and a pinning button projecting from the first end portion towards the pinning hole. The lever is movable between an operative position in which the pinning button extends through the pinning hole and an aligned hole in the inner tube to secure the tubes together, and a retracted position in which the pinning button is spaced from the pinning hole.
