Abstract
A seating furniture chassis comprises a seat surface frame, a lever mechanism, a footrest, a guide element, and a guide rail. The footrest is connected to the seat surface frame by the lever mechanism and is convertible between a folded-in state in which the footrest is arranged below the seat surface frame and a folded-out state in which the footrest forms an obtuse angle with the seat surface frame. The guide element is rigidly connected to the seat surface frame. When the footrest is converted between the folded-out and folded-in states, the guide element is guided in the guide rail, which has a curved shape.
