摘要：1. A pivot device between the cushion and the backrest of a seat, and in
particular a motor vehicle seat, or the like, comprising a fixed side wall (2) provided with a
circular recess, a movable side wall (1) connected to an internally toothed ring (4) which isfitted in the recess (7) of the fixed side wall and, between the side walls, at least a pivotalpawl (28) which has a generally curved shape whose radius is less than that of thetoothed ring, and end lateral surfaces in the shape of an arc of a circle (30, 33, 34), andwhich carries a portion of a set of teeth (36) in confronting relation to the toothed ring, ateach end of the pawl a projection (16, 18, 20, 22) projecting from the bottom of therecess which has surfaces of a shape corresponding to those of the pawl, and a cam (40)movable between a position for locking the pivot in which it maintains the set of teeth(36) engaged with the toothed ring, and an adjusting position in which it releases the setof teeth in order to allow the relative displacement of the side walls, characterized inthat it comprises at least three projections (16, 18, 20, 22) which define three guidingsurfaces (16, 23, 24, 20, 25, 26) for the pivoting of the pawl (28) which are coaxial and havetheir common centre (0, 01 ) located on the periphery of the recess, or even outside thelatter, and which are constantly in contact respectively with the three lateral surface inthe shape of an arc of a circle (30, 33, 34) of the pawl, which have the same centre and arerespectively in the neighbourhood of the apex and the ends of the pawl so that the latteris maintained solely by a fitting between the projections and the cam and, under theaction of the latter, slides on the pivoting surfaces and pivots about an imaginary axispassing through their centre (0, 01 ) between the locking and unlocking positions.
