Abstract
A dental chair has an armrest pivoted to a base at an armrest pivot, and a seat back pivoted to the base at a back pivot located forward of the armrest pivot. The seat back includes a support pin for supporting the armrest at a position forward of the seat back pivot. Moving the seat back from an upright position to a reclined position through a large range of angular motion causes the support pin to elevate the armrest by a substantially smaller angular amount.
