Patent ID: 7441839

Claim:
A chair comprising: a supporting frame; 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 being supported above the supporting frame by its rearward portion; 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 being 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 obtain a net increase in height above the supporting frame and to increase in rearward tilt angle so that a first portion of the rearward portion that is closest to the fold has a greater net increase in height than a second portion of the rearward portion that is farthest from the fold, the seat portion also being configured so that a consequent downward folding of the forward portion about the transverse fold is caused by weight of an occupant's legs when the occupant is seated on the seat portion.
