摘要

The adjusting device (100) has a wedge arrangement (16) arranged at a rotatable hinge (14) in an integrated manner. The wedge arrangement has wedges guided in a reversible manner radial to the rotatable hinge. The wedge exerts axially directed force on the rotatable hinge when a braking or blocking effect is produced by the wedge arrangement by engaging of the wedges between a seat-part sided washer (20) and a backrest-sided washer of the rotatable hinge.
