ARM ASSEMBLY FOR A CHAIR

摘要

An arm assembly (24) is provided for a chair (12). The chair (12) has a forward direction and a rearward direction. The arm assembly (24) comprises an armrest (26) an d a support structure (28). A mounting device movably mounts the armrest to the support structure. The mounting device constrains the movement of the armrest (26) relative to the support structure to movement in a substantially horizontal plane having two degrees of freedom defined by first and second transversely arranged axes lying within the substantially horizontal plane. The armrest (26) thus move in a substantially planar fashi on without changing the orientation of the armrest (26).
