Ski boot

Claim 1

A tensioning device for a cable wire or band wire for utilisation in a ski boot having a casing and a leg portion, more especially a ski boot which is put on by entering the boot from the rear, and wherein the leg portion comprises a sleeve, which forms the front portion thereof, and a cover, which forms the rear portion thereof, as well as a means for securing the leg portions together in the position of use, a pressure distribution plate being disposed inside the shell, preferably between the casing and an inner boot portion, and said pressure distribution plate extends at least over the instep region, preferably to the front part of the foot, and laterally surrounds the foot at least partially; the tensioning device including at least one cable reel mounted in a bearing bush by means of a bearing bolt so as to be rotatable and axially displaceable; wherein the bearing bush forms the rotary member of a freewheel bearing which has a rigid bearing sleeve surrounding the bearing bush and connected to the housing of the tensioning device with wedge locking means operative between the bearing bush and the sleeve for permitting unlimited rotation of the bush in the sleeve in a cable reel-tensioning direction and locking the sleeve against rotation in the bush in a cable reel-relaxing direction; wherein one end of the bearing bush is connected to the cable reel via an engageable and disengageable coupling means; and wherein the other end of the bearing bush is connected to a tensioning disc provided with a rotary knob, a tensioning lever or the like, the bearing bolt extending through the tensioning disc and being connected to a resilient member which is supported on the tensioning disc, the resilient member biasing the engageable and disengageable coupling means into an engaged condition for tensioning the cable reel the coupling means being disengageable by the axial displacement of the bearing bolt in a direction opposite the force of the resilient member.
