ABSTRACT:
An improvement to the seat having relatively adjustable sections disclosed and claimed in U.S. Pat. No. 3,749,442 to restrict the movement of each separate seat section to movement only back and forth in a longitudinal rocking motion as opposed to universal movement, to thereby more effectively and efficiently assist in the comfort of the individual and adjustment of the seat to movements of the user without causing undue fatigue over time. The improvement includes a seat rocking member such as a cylindrical rod affixed to the lower portion of each seat half and a pair of spaced apart resilient receiving members for each seat half to movably and rotatably support a seat half on the base of the seat. The resilience of the receiving members permits the the seat rocking members to vertically move downward within the receiving members when a force such as the weight of a person pushes downward on the seat. The resilience of the receiving members further permits the seat rocking members to rock back and forth to thereby enable the user to independently rock back and forth in a front to back rocking arrangement on each seat half. An adjustable device limits the amount of front to back rocking which can be created.
