Abstract

A chair of the tilting type which includes a base (110), a seat (111) and back (112), with the base (110) pivotally supporting the seat (111) with two parallel links (120, 123) of a four-bar parallel linkage, with one of the links extending to support the back. The four-bar linkage is duplicated on each side of the chair by forming the two opposite parallel links or cranks (123) from the upturned ends of the tubes (113) which pass through the base (110) in parallel but vertically offset fashion, the base (110) thus forming the fixed bar of the linkage with its opposite bar or coupler being formed by the seat (111). Also disclosed is an adjustable armrest (600) and a headrest (370) that is pushed into lace when the chair is reclined and retracted.
