ABSTRACT:
A linkage mechanism is interposed between a pedal and a movable actuating member, and movement of the pedal in one direction is resisted by the extension of a resilient helical spring. The linkage and spring are arranged so that movement of the pedal in such one direction is resisted by a substantially constant force throughout the travel of such pedal in such one direction.
