<p>A synchrotilt chair control in which a heavily loaded toggle linkage or slide arrangement between the rear of the seat support member and the chair back support member is eliminated. By means of an axle (68), the rearward portion of the chair seat support means is pivotally connected directly to the chair back support means and there is a slide (99) and track (20) arrangement between the front of the chair seat support (70) and the front of the stationary housing (10). The front location is relatively lightly loaded as compared to the rear of a chair to which the control is mounted.</p> |
