Abstract
An upper shaft part of the ski boot is pivotable on a lower shaft part about an axis (20) from a standing position, which runs approximately at right angles to the sole (14), into a forwardly inclined rest position which corresponds to the skiing position. This pivoting movement of the upper shaft part (16) when the ski boot is closed is transmitted to transmission members (86), which are displaceable in the longitudinal direction of the boot, by means of actuating levers (82). The movement of the transmission members (86) toward a heel element (98) is converted into a pushing forward of a tensioning member (90) by means of toothed wheels (94). Thereupon, the effective part loops (106,108) of the tensioning element (102), which are guided around the tensioning member (90), are shortened. When the upper shaft part (16) is in the rest position, the foot is consequently retained by the retaining element (96) and the heel cap (100). When the upper shaft part (16) is pivoted back into the standing position, the foot is free inside the ski boot.
