Abstract
Abstract A ski boot has a tongue part forwardly deflectable relative to the shank part connected to the sole of the boot, as the skier's lower legs move in the leaning forward direction. The deflectability of the tongue part can be limited by means of a limiting device consisting of laterally arranged limiting arrangements. By means of actuating elements, the limiting arrangements can be adjusted to different distances of deflection, permitting a more or less leaning forward stance depending on the needs of the skier. A ski boot with such a limiting device permits the skier to effortlessly adjust the degree of limitation in the leaning forward position in any desired way.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
66 words
A ski boot having a shell comprising: a sole; a shank coupled to said sole; a tongue deflectable relative to said shank in a leaning forward direction under stress in the lengthwise direction of the boot; and means for limiting the distance to be travelled by said tongue, said limiting means operatively connecting said tongue and shank, and said limiting means having at least one stop.
Claim 2
Dependent Claim
66 words
A ski boot having a shell comprising: a sole; a shank coupled to said sole; a tongue deflectable relative to said shank in a leaning forward direction under stress in the lengthwise direction of the boot; and means for limiting the distance to be travelled by said tongue, said limiting means operatively connecting said tongue and shank, and said limiting means having at least one stop.
Claim 3
Dependent Claim
46 words
A ski boot according to claim 1, wherein said limiting means comprises two identical devices for limiting the leaning forward position of said tongue, said limiting devices being positioned opposing each other on opposite sides of the boot relative to the lengthwise plane of the boot.
Claim 4
Dependent Claim
67 words
A ski boot according to claim 1, wherein each limiting means has a counterstop, wherein one of said tongue and said shank has said counterstop adjustably supported therein and the other one of said tongue and said shank has said stop formed therein, such counterstop being reversible between a first position and a second position in the former of which it cooperates with and engages said stop.
Claim 5
Dependent Claim
57 words
A ski boot according to claim 3, wherein the counterstop is formed by a flattened head on a peg, said peg being rotatably supported in the tongue, said flattened head engaging a slot formed in a lateral portion of the shank and extending in the leaning forward direction of said tongue, and said slot containing said stop.
Claim 6
Dependent Claim
74 words
A ski boot according to claim 4, wherein said slot has a wide zone and a narrow zone wherein said stop being formed by the separation of said zones, said narrow zone following said wide zone in the leaning forward direction, the width of said narrow zone being dimensioned in a way such that the flattened head of said peg fits into said narrow zone only when said counterstop is in its second position.
Claim 7
Dependent Claim
20 words
A ski boot according to claim 4, wherein the angle of rotation of the peg is limited to 90° .
Claim 8
Dependent Claim
23 words
A ski boot according to claim 3, wherein the actuating element comprises a toggle, said toggle being torsionally rigidly connected with the peg.
Claim 9
Dependent Claim
27 words
A ski boot according to claim 5, wherein the narrow zone of said slot ends in a second stop for engaging the flattened head of the peg.
Claim 10
Dependent Claim
70 words
A ski boot according to claim 1, wherein each limiting means has a limiting element providing at least two counterstops for providing for different distances of travel of said tongue in the leaning forward direction, such limiting element being reversible between at least two positions, so that in a first position the first counterstop cooperates with said stop, and in a second position the second counterstop cooperates with said stop.
Claim 11
Dependent Claim
37 words
A ski boot according to claim 9, wherein the limiting element is connected to an actuating element and is adjustably secured on the tongue, and said stop is rigidly arranged on the shank of the boot shell.
Claim 12
Dependent Claim
37 words
A ski boot according to claim 9, wherein a peg is rotatably retained in said tongue and is operatively positioned in a slot formed in said shank, said limiting element secured to and rotatable with said peg.
Claim 13
Dependent Claim
34 words
A ski boot according to claim 11, wherein said counterstops are formed by plane surfaces on said limiting element, said plane surfaces being disposed with different spacings from the rotary axis of said peg.
Claim 14
Dependent Claim
18 words
A ski boot according to claim 12, wherein said counterstops are formed by a single, spirally extending surface.
Claim 15
Dependent Claim
22 words
A ski boot according to claim 9, wherein said limiting element and said stop is arranged on the inside of the boot.
Claim 16
Dependent Claim
22 words
A ski boot according to claim 9, wherein said limiting element and said stop is positioned between the shank and the tongue.
Claim 17
Dependent Claim
44 words
A ski boot according to claim 9, wherein said actuating element connected to the limiting means is positioned on the outer side of the boot shell and said actuating element has a toggle capable of movement between a folded open and folded back position.
Claim 18
Dependent Claim
20 words
A ski boot according to claim 16, additionally including locking means for releasably securing said toggle in its folded-back position.
Claim 19
Dependent Claim
41 words
A ski boot according to claim 17, wherein said toggle has cams formed thereon and said tongue has recesses formed therein for releasably receiving said cams, said cams and recesses thereby cooperating with one another to secure said toggle against rotation.
