Abstract:
1. 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, 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 as the back portion is reclined; the chair configured such that: when the chair is not occupied, the entire seat portion is moved to obtain a net increase in height above the supporting frame upon a reclining action of the back portion; and when the chair is occupied, the rearward portion of the seat portion is moved to obtain a net increase in height above the supporting frame upon a reclining action of the back portion, with the consequent downward folding of the forward portion about the transverse fold caused by weight of an occupant's legs.
