SEAT
First Claim
1. A seat comprising a seat pan, a backrest and a support structure, wherein the seat pan is pivotally coupled to the support structure about a first pivot axis (P1) provided extending across the seat pan substantially at the front edge of the seat pan, such that the seat pan may be pivoted about the said first pivot axis in use, and the angle of the seat pan relative to the support structure may thus be adjusted, the backrest being pivotally coupled to the seat pan about a second pivot axis (P2) extending across the seat pan substantially at the rear of the seat pan, such that the angle of the backrest relative to the seat pan may be adjusted in use, the backrest being linked to the seat structure by an articulating linkage whereby in one mode of operation as the backrest moves forward during forward tilting movement of the seat from a rest position (Delta) to a second position (Delta 2) the seat pan rear tilts upwardly relative to the seat pan front and the backrest rises therewith but the angle between the seat pan and backrest adjusts substantially simultaneously so that the backrest'"'"'s angle of incline relative to the floor level/horizontal is substantially unaltered.

Abstract
A seat comprising a seat pan (12) and a support structure, wherein the seat pan (12) is pivotally coupled to the support structure (8) about a first pivot axis (pi) provided across substantially the front of the seat pan (12), such that the seat pan (12) may be pivoted about the said first pivot axis (pi) in use, and the angle of the seat pan (12) relative to the support structure (18) may thus be adjusted. The seat further comprises a backrest (14), the backrest being coupled (p2) to substantially the rear of the seat pan (p2). Also provided is pneumatic apparatus for use with a seat, comprising one or more inflatable cushions for supporting a user in use. Further provided is an armrest comprising: a first pivot axis about which the armrest may be pivotally coupled to a seat, the first pivot axis being arranged to orient sideways out of the seat and thereby enable upward and downward rotation of the armrest in use; and a second pivot axis oriented parallel to the longitudinal dimension of the armrest, the armrest being rotatable about the second pivot axis in use.
