Abstract
A chair includes a supporting frame and a seat portion which is foldable about a transverse fold to define a rearward portion behind the transverse fold and a forward portion, forward of the transverse fold. The seat portion is supported above the supporting frame by its rearward portion. The chair also includes a reclinable back portion and a recline mechanism with which the back portion is connected for reclining action of the back portion. The recline mechanism is operably linked to the rearward portion of the seat portion such that on reclining action of the back portion, the rearward portion is moved to increase in rearward tilt angle and to obtain a net increase in height above the supporting frame, with a consequent folding of the seat portion about the transverse fold line under the weight of the occupant.
