Swiveling user support for exercise machine

摘要

A swiveling user support assembly has a user support or seat rotatably mounted on a user support mounting device or frame for rotation about a first pivot axis, while the mounting device or frame is pivotally or rigidly connected to a main frame of an exercise machine. The user support has a base, and a primary user support and stabilizing device mounted on the base. A pivot connection between the base and mounting device or frame allows the user support to swivel from side to side about the first pivot axis. A centering mechanism helps to orient the user support in a central position for user entry or exit.

主权项

1. An exercise machine, comprising:
a stationary main frame having a forward end and a rear end; a user support mounting device associated with the main frame; a user support which is adapted to support a 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 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 adapted for engagement by a user during performance of 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; and the first part comprising a releasable positioning device which is movable between a retracted position and an advanced position, and the second part having only one engagement formation adapted to engage with the positioning device in the advanced position only when the user support is in the central, forward facing position, whereby the one engagement formation defines the central, forward facing position of the user support and is not engageable with the positioning device in any other position of the user support during a user controlled swivel movement.
