1. An apparatus for adjusting the height of the upper fixing or guide fitting for the shoulder belt of a safety belt system, with said belt being looped through said fitting, resulting in a belt looping axis;

  • said apparatus comprising;

    a guide rail having a guide slot and recesses;

    a sliding member which is movable within said guide slot of said guide rail, said fixing or guide fitting being supported on said sliding member;

    at least one locking member mounted on said sliding member and adapted to engage in said recesses of said guide rail for selective locking and releasing of said sliding member relative to said guide rail, said at least one locking member being symmetrical in construction with regard to its locking and releasing function;

    said belt looping axis, at said fixing or guide fitting, being located externally of the zone in which the forces between said at least one locking member and said guide rail are transmitted along a plane, a line, or pointwise when said sliding member is locked relative to said guide rail; and

    operating means for selectively locking said at least one locking member into, and releasing it from, said recesses of said guide rail to effect said selective locking and releasing of said sliding member relative to said guide rail;

    said operating means having a finger pressure construction to permit operating thereof with one hand and with substantially no force of hand and arm, a spring-loaded locking member which is longitudinally movable at right angles to the direction of slide of said sliding member; and

    in which said operating means for selectively locking and releasing said lockingmember is in the form of a sliding key which is movable parallel to said guide rail in the manner of a known belt buckle having a PRESS buttom, and, by means of suitable configuration, controls the longitudinal movements of said locking member.
