ABSTRACT:
A seat having a seat frame mounting a seat bottom, a seat back extending upwardly from the back of the seat bottom and a leg rest extending downwardly in an area forward of a front side of the seat bottom. The seat includes the combination of a seat bottom extension for increasing or decreasing the length of the seat bottom between the seat back and the leg rest to fit the distance between the buttocks and the back of the knees of the occupant. The seat bottom extension has a seat bottom extension assembly on which the leg rest is mounted for movement therewith and an adjustment assembly for adjustably mounting the seat bottom extension assembly to the front side of the seat bottom. The seat bottom extension is mounted for incremental movement between a first position wherein the seat bottom extension is retracted to a position adjacent the front side of the seat bottom and a second position wherein the seat bottom extension is extended to a position spaced apart from the front side of the seat bottom to thereby increase the length of the seat bottom between the seat back and the leg rest to fit the distance between the buttocks and the back of the knees of the occupant.
