Ski boot

Abstract

A ski boot includes a substantially rigid foot-casing that accommodates a user's foot; a substantially rigid cuff enclosing the lower leg of the user and hinged to the foot-casing for swinging about a first rotation axis substantially perpendicular to a midplane of the ski boot; a protective innerboot within the foot-casing and adapted to accommodate the user's foot; and a manually-operated cuff closing assembly adapted to tighten the cuff on the user's leg, and in turn includes: a manually-operated tensioning device rigidly fixed on a first lateral side of the cuff; a flexible ribbon having two ends rigidly fixed to the second lateral side of the cuff opposite to said first lateral side, and extends grazing the front part of the cuff up to the tensioning device; and a coupling member is fitted in free slidable manner on said flexible ribbon, to couple in releasable manner to said tensioning device.

1 . A ski boot comprising: a substantially rigid foot-casing, which is adapted to accommodate the user's foot; a substantially rigid cuff, which is adapted to enclose the lower leg of the user, and is hinged to the foot-casing so as to be able to swing about a first rotation axis substantially perpendicular to the midplane of the ski boot; a protective innerboot, which is placed within the foot-casing and is adapted to accommodate and to protect at least the user's foot; a manually-operated foot-casing closing assembly, which is capable of tightening the foot-casing on the user's foot; and a manually-operated cuff closing assembly, which is adapted to tighten the cuff on the user's leg;
 the cuff closing assembly comprising: a manually-operated tensioning device, which is rigidly fixed on a first lateral side of the cuff; a flexible transversal band, which is rigidly fixed to a second lateral side of the cuff opposite to said first lateral side, and extends grazing to the front part of the cuff up to reach said tensioning device and a coupling member, which is located on the transversal band and is structured so as to couple in releasable manner to said tensioning device;   wherein the transversal band comprises a flexible ribbon, which has its two ends rigidly fixed to the second lateral side of the cuff and extends grazing the front part of the cuff up to reach the tensioning device; and   wherein the coupling member is fitted in free slidable manner on said flexible ribbon.   
     
     
         2 . The ski boot according to  claim 1 , wherein the flexible ribbon is bent in a substantially V shape and has the two ends fixed on the second lateral side of the cuff, one spaced above the other; the coupling member being placed on the bend of the flexible ribbon. 
     
     
         3 . The ski boot according to  claim 1 , in which one of the two ends of the flexible ribbon is fixed to the cuff in a manually adjustable manner. 
     
     
         4 . The ski boot according to  claim 3 , wherein the first end of the flexible ribbon is fixed to the cuff via a mechanical self-locking member that, in turn, is rigidly fixed to the second lateral side of the cuff. 
     
     
         5 . The ski boot according to  claim 1 , wherein said tensioning device comprises: a support base, which is rigidly fixed to the cuff; and a manually-operated tensioning lever, which is butt-hinged to the support base so as to be able to freely rotate about a second rotation axis, and is provided with at least one housing seat adapted to be engaged in removable manner by said coupling member. 
     
     
         6 . The ski boot according to  claim 5 , wherein said tensioning device additionally comprises: a manually-operated retention lever, which is butt-hinged to the support base or to the tensioning lever so as to freely rotate from or towards a closing position, in which it is substantially skimmed over the side of the tensioning lever where the housing seat is located, so as to prevent the exit of the coupling member from said housing seat;
 and an elastic member, which is adapted to bring and to maintain, in an elastic manner, the retention lever in said closing position.   
     
     
         7 . The ski boot according to  claim 6 , wherein the retaining lever is butt-hinged to said support base so as to freely rotate about said second rotation axis. 
     
     
         8 . The ski boot according to  claim 7 , wherein the retaining lever is butt-hinged to said tensioning lever so as to freely rotate about a third rotation axis parallel to said second rotation axis. 
     
     
         9 . The ski boot according to  claim 5 , wherein the tensioning lever is substantially U-shaped, and the free ends of the two arms/prongs of the tensioning lever are fitted in rotatable manner onto a transversal pin fixed to said support base. 
     
     
         10 . The ski boot according to  claim 9 , wherein the proximal end of the retaining lever is fitted in freely rotatable manner on said transversal pin, between the free ends of the two arms/prongs of the U-shaped tensioning lever. 
     
     
         11 . The ski boot according to  claim 5 , wherein said housing includes a transversal rectilinear groove that extends on the central segment of the tensioning lever parallel to said second rotation axis, advantageously for the entire width of the same tensioning lever. 
     
     
         12 . The ski boot according to  claim 11 , wherein said transversal rectilinear groove has a profile shaped substantially like an overturned-T or like a dovetail. 
     
     
         13 . The ski boot according to  claim 1 . wherein the first lateral side of the cuff, the outer lateral side of the cuff, and the second lateral side of the cuff is the inner lateral side of the cuff.
