Abstract

A chair control includes a fixed housing, a back support bracket rotatably secured to the fixed housing for movement about a back tilt axis between a fully upright position and a fully reclined position, and an energy source for biasing the back support bracket toward the fully upright position. A tension adjustment mechanism including a bell crank is pivotally attached to the fixed housing, the bell crank including a first leg having a threaded member thereon and a second leg operably engaging the energy source. The tension adjustment mechanism further includes a threaded rod engaging the threaded member and rotatably engaging the fixed housing so that the threaded rod can be rotated to move the threaded member along the rod in a selected axial direction to thus pivot the bell crank and in turn change the tension provided by the energy source.
