Abstract:
1. An exercise machine, comprising: a stationary main frame having a forward end, a rear end, and opposite sides; a user support mounting device associated with the main frame; a user support which is adapted to support to user in an exercise position while performing an exercise; a pivotal connection between the user support and the user support mounting device which defines a user support pivot axis which permits free swiveling of the user support relative to the user support mounting device during an exercise at least through arcuate paths on each side of a central, forward facing, position of the user support, whereby rotation of the user support about the user support pivot axis during an exercise comprises a user-controlled swivel movement; a user engagement device movably associated with one of the main frame, user support, and user support mounting device which is configured for engagement by a user to perform an exercise while positioned on the free swiveling user support; a centering device between the user support mounting device and user support which releasably holds the user support in the central, forward facing position, the centering device comprising first and second parts, one of the parts being located on the user support and the other part being located on the user support mounting device; the first part of the centering device comprising a releasable locking device and the second part having a central opening for releasably receiving the locking device when the user support is in the central position, the locking device including a biasing mechanism for biasing the locking device into the opening when the user support is in the central, forward facing position; and the second part of the centering device having ramp surfaces on each side of the central opening which urge the locking device towards a retracted, spring biased position as the user support is rotated in either direction towards the central position, whereby the retracted locking device is biased outwardly to spring into engagement with the central opening when the user support reaches the central, forward facing position.
