Abstract
A treadmill (10) includes a frame (12) on which are rotatably mounted first and second transverse roller assemblies (14, 16). An endless belt (18) is trained about the roller assemblies. A deck (20) is disposed between an upper run of the belt and the frame. The deck is supported spaced from the frame by a plurality of cup-shaped elastomeric springs (22). The elastomeric springs reversibly deform upon downward deflection of the deck toward the frame. Each elastomeric spring (22) has a sidewall (50) tapering in thickness. The resistance to the downward travel of the deck provided by the elastomeric springs is proportional to the degree of deflection of the deck toward the frame.
