LEG EXERCISE MACHINE WITH SELF-ALIGNING PIVOTING SEAT
First Claim
1. A leg exercise machine, comprising:
- a main frame having a front end and a rear end;
a user support pivotally mounted relative to the main frame to support a user in a seated position and moving in a first direction between a start position and an end position during an exercise movement, the user support having a seat portion and a backrest portion, the seat and backrest portions being in a fixed orientation relative to one another during an exercise movement and moving together in the same relative orientation to one another throughout the exercise movement, the seat portion having a rear end and a forward end and rotating downwardly at its rear end and upwardly at its forward end between the start and end positions of the exercise movement;
at least one leg exercise arm movably mounted relative to the main frame and having a leg engaging device for engagement by the legs of a user seated on the user support to perform a leg exercise;
a connecting link which links movement of the exercise arm by a user performing a leg exercise to movement of the user support from the start position to the end position; and
a load which resists movement of at least one of the user support, exercise arm, and connecting link.

Abstract
An isolation exercise machine for exercising one muscle group has a user support which is pivotally mounted on a main frame by a pivotal mounting system. A user engaging exercise arm is pivotally connected to the user support, and a connecting link links movement of the user exercise arm to movement in the user support. A load provides resistance to movement of the user support, exercise arm and/or connecting link. The pivotal mounting system is configured to place the user support seat in a relatively flat position in the rest or exercise start position and to recline and change the seat angle to an inclined position as the exercise arm is moved.
