A BACK PORTION FOR A CHAIR WITH A MOVEABLE UPPER SECTION

摘要

A back portion 2015 for a chair 2010 has a lower portion 2027 to extend across at least a major part of a lower region of an adult occupant's back and an upper portion 2029 to extend across and support at least a major part of an upper region of an adult occupant's back. The upper portion 2029 has an upper section 2029a and a remainder 2029b below the upper section. The upper section 2029a is forwardly biased into a position in which it is generally aligned with the remainder of the upper portion, but folds rearwardly relative to the remainder 2029b of the upper portion when a rearward and downward force is applied to the upper section to reduce the overall vertical height of the back portion and to provide a platform for resting the occupant's arm.
