Abstract

A seat including a seat back and a seat bottom which is pivotally mounted is disclosed. The seat bottom is pivotally mounted for rotational movement between a first position wherein the seat bottom is substantially horizontal and a second position wherein the seat bottom is angled relative to a horizontal plane. The seat also includes means for maintaining the seat bottom in a number of positions intermediate the first and second positions. An occupant of the seat can select a seat bottom position which provides the best balance between the shock absorbing functions provided by the knees and the posterior.
