The assembly of claim 1, wherein said mounting means for sufficient tooth engagement comprises sufficient idle connection means for effecting displacement of a single tooth pitch. An assembly as set forth in claim 5 wherein one of said toothed means is said idled toothed pole. An assembly as claimed in claim 6 comprising means for centering the pawl with respect to the idle during initial tooth engagement. The assembly of claim 1 wherein one of the members comprises a toothed sector having a jade center coinciding with the pivotal connection member. 9. An assembly according to claim 8, wherein one of said toothed means is a toothed pawl revolving with another member and engageable with a toothed sector, said pawl being fixed in a controlled position by said cam means. The assembly of claim 1 wherein said rotatably connected member consists of a bracket member of a hinge. The assembly of claim 1 wherein the pivotally connected member consists of a hinged bracket member that can be used as a hinge of an adjustable seat back. 12. The apparatus according to claim 11, comprising manually adjustable handle means for operating the cam means in the release position for effective adjustment, and elastic means for returning the cam means to the engaged position upon manual release of the handle. Assembly. 13. An assembly as claimed in claim 12 comprising dual cam means each rotatably arranged separately operated by manipulation of a single handle. 10. The assembly of claim 9 including a handle actuated resilient connector for separating the pawl following separation of the cap means and for sufficiently restoring the engagement of the pawl prior to recombination of the cam means. An assembly as claimed in claim 9 comprising means for centering the poles for recombination at any controlled position of the sector within the idle limits of the pole connection. An assembly as claimed in claim 1 comprising means for attaining a relative axial tooth displacement when preliminary engagement of each tooth tip interferes with sufficient tooth engagement. An assembly as claimed in claim 9 comprising means for laterally moving the poles in the presence of an aligned preliminary toothed engagement of the pawls and sector teeth that interferes with sufficient tooth engagement. The apparatus of claim 15 comprising means for laterally moving the pawl from its centered position when there is an aligned relative toothed engagement that interferes with sufficient toothed engagement in the adjusted position. Assembly. 20. The assembly of claim 18, wherein the means consists of a protrusion protruding from the pawl such that the means is engageable by an extension of the handle when recombination of the pawl and the lateral tooth in the adjusted position is stopped. 20. The apparatus of claim 19, wherein the protrusions and extensions form sharp edges that are mutually engageable when recombination of the pawls and the lateral teeth in the adjusted position is interrupted, and the clearances of the respective sharp edges are defined by the sharp edges. An assembly of bars that provides a boundary between engagement and bypassing relationships.
