Patent ID: 7060012

Claim:
A resistance module configured for an exercise machine for providing a substantially constant force through a range of motion, comprising: at least one cantilever spring and at least one rigid member movable with respect to one another along a path of travel with the at least one rigid member causing the at least one cantilever spring to deflect and produce a resistance force as the at least one cantilever spring and the at least one rigid member move with respect to one another along the path of travel; the cantilever spring having an anchored end and a deflection end; the at least one rigid member engaging the deflection end of the cantilever spring, and constraining the deflection end to a predetermined path of deflection as the at least one cantilever spring and the at least one rigid member move with respect to one another; means for operatively coupling at least one of the cantilever spring and the at least one rigid member to an exercise machine; and an active element engageable by a user and operatively coupled to the resistance module.
