Exercise machine adjustment mechanism

摘要

An adjustment mechanism for an exercise machine enables the relative position between a support for the operator of the machine and an exercise member to be adjusted by the operator while in the exercise position. In a particular embodiment, the mechanism adjusts the longitudinal position of a pedal assembly of a recumbent bike exerciser. The operator is supported by a seat on a fixed frame member, and the pedal assembly is mounted on an extension member that slides longitudinally with respect to the fixed frame. Various mechanisms are provided for the operator to conveniently position the pedal assembly relative to the seat while the operator is seated in an exercising position.
