Abstract

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 at the front of the seat pan such that the seat pan may be tilted upwards. The backrest is pivotally coupled to the rear of the seat pan and the angle of the backrest to the seat pan may be adjusted in use. The backrest and pan are connected by an articulating linkage such that when the seat pan is tilted about the first axis from a rest position (figure 1) to a second position (figure 3) the backrest's angle of incline relative to the floor level is substantially unaltered. Also claimed is a pneumatic cushion for use with a seat: an armrest with a first pivot axis about which the armrest may be pivotally coupled to a seat, 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.
