The invention relates to a lift guide with a symmetry axis OY, consisting of a mushroom-shaped element and two flanges, each side of the mushroom element being provided with a side braking and guiding surface for the lift-braking and -guiding elements. The invention is characterized in that the mushroom element includes a head which limits movement of the braking and/or guiding elements along the axis. The head of the mushroom element has: two side braking and/or rolling surfaces, on either side of the symmetry axis, which converge toward one another in the direction of the interior or exterior of the mushroom element; and larger dimensions along the OX axis than the side braking/guiding surfaces. |
