ABSTRACT:
An apparatus provides a linearly decreasing force. The apparatus includes a plurality of links, which can be referred to as swing, seat, fixed, and input/output links. A spring is coupled to each of the seat links, and a rod is positioned in proximity to each spring and through each of the seat links. A load applied to the input/output link will experience a linearly decreasing resistance.
