A hinge is made for connecting a sofa seat and a back which must be mutually pivotal. Each furniture portion has a circumferential frame of metal tube and has furthermore one or more tube projections (11) opposing corresponding projections (12) on the other furniture portion. Each tube projection (11) is provided with a bundle (21) of parallel sheet-shaped hinge means (121a, 121b) which by means of a main pin (23) are hinged to another almost corresponding bundle (22) of parallel sheet-shaped hinge means (122a, 122b) on the opposing tube projection (11) on the other furniture portion. Every second hinge means in each bundle (21) is constituted by a hinge lap (121b), and the other hinge means in the bundle are constituted by an angle controlling lap (121a). Opposing hinge laps (121b, 122b) are inserted so much between each other that the main pin (23) can connect them, and the hinge lap (121b) and the angle controlling lap (121a) are placed in such a way that each hinge lap (121b) in one bundle (21) is always in register with an angle controlling lap (122a) in the other bundle (22). The hinge lap (FIG. 5) and the angle controlling lap (FIG. 6) have means (38a, 38b, 45) for restricting the angle of rotation (v) of one furniture portion relative to the other furniture portion. The hinge allows a reliable limitation of the angular range within which the furniture portions may turn relative to each other. |
