1. A guide rail for guiding a hand-held power tool, wherein the hand-held power tool has a drive motor, a working tool driven by the drive motor, and a protective cover for the working tool which can be moved between an open position exposing the working tool, and a covering position at least partially covering the working tool, wherein a rail body of the guide rail has, on opposite sides with respect to a center plane of the rail body, a resting surface for laying onto a base surface, of a workpiece, and a guide surface for guiding the hand-held power tool, on which guide surface a guide contour for guiding the hand-held power tool along a guide axis is arranged such that the working tool of the hand-held power tool, guided parallel to the guide axis, can cut into the workpiece in a working direction adjacently to a longitudinal narrow side of the rail body, and wherein the guide rail has a stop assembly having at least one opening stop for moving the protective cover into the open position when the hand-held power tool is moved along the guide axis and wherein the at least one opening stop can be moved on the rail body between a stop position for actuating the protective cover toward the open position and a release position for releasing the protective cover for movement toward the covering position, wherein the opening stop projects further from the longitudinal narrow side of the rail body, with a direction component parallel to the center plane of the rail body, in the stop position than in the release position, wherein the at least one opening stop has a lower surface, the at least one opening stop being in the stop position for actuating the protective cover toward the open position when the lower surface rests on the workpiece.
