Abstract:
1. A resistance unit, comprising: a body; a rotatable member mounted to the body for rotation relative to the body, wherein the rotatable member is located exteriorly of the body and is rotatable relative to the body about an axis of rotation; an electrically conductive member interconnected with the rotatable member for rotation with the rotatable member; a magnetic member located within a passage defined by the body and spaced from the rotatable member, wherein the magnetic member interacts with the electrically conductive member to establish eddy current resistance to rotation of the rotatable member upon rotation of the rotatable member; and an adjustment mechanism interposed between the body and the magnetic member, wherein the adjustment mechanism is configured and arranged to move the magnetic member toward and away from the rotatable member in a direction parallel to the axis of rotation of the rotatable member to vary the eddy current resistance to rotation of the rotatable member.
