Abstract: Continuous joint permitting automatic compensation of clearances consisting of a fixed plate integral with the seat part and a moving plate integral with the back, this assembly capable of having an angular movement of one of the parts in relation to the other in which: an elastic bearing is inserted between the eccentric constituting a cam and a tooth part which it drives. One of the plates is provided with a shaft which is seated in a bearing aperture of the eccentric constituting a cam bearing aperture which is provided with two main support zones on which the shaft bears.

Abstract: Continuous joint for seat permitting compensation of clearances consisting of a fixed plate integral with the seat part and a moving plate integral with the back, this assembly capable of having an angular movement of one of the parts in relation to the other in which:(a) An elastic bearing (19) is inserted between the eccentric constituting a cam (13, 22) and the part which it drives (4, 21).(b) The central rotational shaft of the eccentric constituting a cam (13) has a flat part giving two opposite bearing points (17, 18) essentially at 120.degree. in relation to each other on the interior zone of the hole (16) of the moving plate (2) in order to compensate for the tolerance clearances inherent in the manufacture of the continuous joint.
