Abstract
An 'invisible' syncro tilt mechanism is provided for chairs. The chair has a seat with a back portion and a seat pan portion and the seat pan portion is connected to the back portion and to a pivotable support structure, and thereby to a base. The mechanism has a generally closed track defined in the seat pan portion. A plunger is attached to a front portion of the pivotable support structure. The plunger is slidably disposed in the track. A spring is disposed in the track which is connected at opposing ends to the plunger and to a front end of the track. The mechanism does not extend or protrude outside of the seat pan. The mechanism provides synchronous movement of the plunger in the track.
