Abstract
An exercise treadmill (10) includes a deck assembly (12) having a rearward end portion pivotally mounted on an underlying frame (14). A powered endless belt (100) is mounted on the deck assembly (12) to present a moving surface which slides over the top of the deck assembly. The forward end of the deck assembly is supported by a suspension system (20) utilizing lever arms (160L and 160R) mounted on the frame (14) to pivot about an axis (169). The lever arms are pivotally interconnected with the deck at a location distal from the pivot axis of the lever arms. Dampeners in the form of shock absorbers (178) are connected between the lever arms and the frame to impart a progressively increasing damping force on the lever arms as the lever arms rotate about their pivot axis under the influence of the descending deck.
