Abstract

An articulated joint for swivel back rests for chairs comprises an iron fitment (1) firmly connected to the seat face frame (2) of the chairs, an iron fitment (3) firmly connected to the back rest (4) an internally toothed spur gear (5) connected to one of the iron fitments and an externally toothed disc (6) firmly connected to the other, the eccentricity e between the spur gear (5) and the toothed disc (6) being chosen so that a space is formed radially between these two inter-engaging parts or more specifically between the two cylindrical faces connecting the tips of the teeth. This space has the general shape of a half moon which extends over an arc of about 180 deg. whilst the rotating operating member which is accessible to the seat occupant is a half-moon member (11) with a smooth inner and outer face which practically fills up the space, suitably connected without rotation to the actuating member (8).
