Abstract (en)
[origin: US4684278A] A joint for use in a collapsible chair has a main component with a stub which is connectable with the seat of the chair and is integral with a housing for the flat shorter arms of first and second two-armed levers each of which is pivotally secured to the housing by a rivet. The longer arm of the first lever is connected to the back and the longer arm of the second lever is connected to the rear foot of the chair. The shorter arms of the levers are coupled to the respective end portions of a link by two pivot members whose axes are parallel to the axes of the rivets. The levers are pivotable relative to the main component between (a) operative positions in which the chair is erected and the axis of the rivet for the first or second lever is disposed in the common plane of the two pivot members, and (b) inoperative positions in which the chair is collapsed and the longer arms of the levers are adjacent and parallel to the stub of the main component.
