Abstract
A modular chair mechanism for limiting travel and adjusting tension in a chair is provided. The chair mechanism generally includes a shuttle that travels inside a housing, with a biasing member that applies tension during travel of the shuttle. An interface is coupled to the shuttle that alters the amount of force required to cause the shuttle to travel. In embodiments, the chair mechanism limits travel of a chair back support assembly to a number of positions based on travel of a shuttle inside the mechanism housing. For example, a feature on an end of the shuttle may selectively abut one of a plurality of retention means on the housing, which determines how far the shuttle may travel in that position. The amount of tension in the biasing member may also be affected by a self-weighing mechanism that applies an initial amount of force against a biasing member.
