Ski boot with selective tensioning device

A ski boot comprising:

• a sole;
• a shaft, a lower shaft part thereof enclosing the foot, a front shaft part surrounding the lower tibia area, and a rear shaft part provided in the area of the heel and the lower fibula and being pivotable about an axis which runs approximately parallel to the sole and transversely to a longitudinal direction of the boot;
• and
• a foot retaining device arranged inside the ski boot and being connected to a tensioning device, the tensioning device actuated by means of pivoting of the rear shaft part;
• wherein the front shaft part is mounted on the lower shaft part about a pivoting axis which runs approximately parallel to the sole and transversely to the longitudinal direction of the boot, the front and rear shaft parts jointly pivotable out of a standing position when the ski boot is closed running approximately perpendicularly to the sole, into a forwardly inclined rest position, and wherein the tensioning device, driven by said joint pivoting movement of the front and rear shaft parts, tensions the foot retaining device;
• and
• wherein the foot retaining device comprises a tensioning element and the tensioning device comprises a tensioning member which acts on the tensioning element for the tensioning of the tensioning element upon the pivoting of the front and rear shaft parts into the rest position and which is displaceable in the longitudinal direction of the boot by means of an actuating member connected to one of the front and rear shaft parts, the actuating member being arranged inside the ski boot, pivotable about the pivoting axis of one of the front and rear shaft parts respectively and connected to a transmission member displaceable in the longitudinal direction of the boot in the sole area and connected to the tensioning member by means of a gear which reverses the direction of movement, and wherein the tensioning element is guided from behind, in the longitudinal direction of the boot, to the tensioning member.

• and
• wherein the foot retaining device comprises a tensioning element and the tensioning device comprises a tensioning member which acts on the tensioning element for the tensioning of the tensioning element upon the pivoting of the front and rear shaft parts into the rest position, the tensioning element forming at least one endless loop and being guided around the tensioning member to adjust the effective loop length upon the displacement of the tensioning member in the longitudinal direction of the boot.
