ABSTRACT:
A chair tilt mechanism incorporating a tilt stop and height adjustment mechanism on a single lever is disclosed. In addition, the component parts of the chair tilt mechanism can be formed by conventional stamping operations which allows for the standard components to be used for a wide variety of chair tilt applications. The chair tilt mechanism includes a housing mounted to the support spindle and rails mounted to the underside of a chair. The rails are pivotally mounted to the housing and a load bracket member is fixedly mounted to the rails. A tilt adjustment spring extends between the load bracket and the housing. A lever is received within the housing and is laterally movable within the housing to selectively engage a tilt lock and adjust the height of the chair.
