1. An adjustment mechanism for mine lining units, equipped with a servo-motor connected by an articulated joint at one end to a sill-piece construction and at the other end also by an articulated joint to a lever system, characterized in that it has a profiled flexible connector (4) of variable cross-section, connected at one end by an articulated joint to a holder (10) of a sill-piece (1) and through the other end through an articulated joint (8) connected to a servo-motor (2), while the profiled flexible connector (4) is simultaneously connected by an articulated joint to a rotating and sliding flat flexible connector (6).<IMAGE>
