Seating structure and methods for the use thereof

Abstract

A seating structure has an articulated seat and back. A rear portion of the seat is automatically pivotable relative to a forward portion of the seat as the seat is tilted between upright and reclinedtilt positions. An upper portion of the back is pivotable relative to the lower portion between a neutral position and an extended position, with the upper portion being pivotable relative to the lower portion independent of the tilt position of the back. In one aspect, an adjustment mechanism is coupled between lower and upper back support members and pivots the upper support member between at least first and second support positions. A seat with an adjustable seat depth is also provided, along with various methods for operating the different aspects and embodiments of the seating structure.
