Company R β c a r ο GtnbHe & Co », Stuttgart, Augustenstrasseβ 8θ - 82 Hinge fitting

The invention relates to an articulated fitting, in particular for seats with an adjustable backrest, with a pawl = lock for locking the pivotably connected parts, for example the fitting parts associated with a seat part bw, the backrest, the pawls = lock a proportional to the The pivoting angle of the backrest shifting and at least over an angular range corresponding to the desired pivoting angle extending ring gear and a pivotably mounted pawl ₈ which is coupled to an actuator which inevitably brings it into and out of engagement with the ring gear _o

In a known hinge fitting of this type for motor = convincing seats of the ring gear is designed as a gear which is rotationally fixedly connected to a pinion lst _s meshing = segment with at the intended the backrest associated fitting part dental _o is to pivoting of the pawl them with a

j The invention, the object is to reasons _e a Gelenkb © -

cleverly create »the also in the axial direction

small drafts can be carried out and a constructive one

professionally trained and therefore cheap to manufacture into

Starting from a hinge fitting of the initially mentioned type, this object is erfindun & convention under solved in that the locking pawl a it comprises elongating sweiten lever arm about its pivot axis out and that sum pivoting of the pawl "ine means of the actuating member rotatable cam is provided _s on the cam depending on the angular position and device one or the other lever arm of the pawl runs up »

By extending the pawl backwards beyond its pivot axis, the system is extremely simple to ensure that a compulsory “continuous movement of the pawl can be brought about in both pivoting directions by means of a cam disk”, which is a structurally simple and robust force transmission element, and in this respect too _s advantageous as di @ pawl is arranged as them in the "same level and therefore keinmsusätslichen axially Plata needed"
