Abstract
Abstract The safety binding comprises a vertical pivot integral with a base mounted to the ski, a binding rotating upon the pivot and carrying means for retaining the boot, a locking system ensuring that the boot is maintained in a specific position upon the ski, and a compensating mechanism acting upon the locking system to cause a lateral retention force applied to the boot to vary inversely to a vertical retention force. The compensating mechanism includes a first part mounted to pivot about an axis at right angles to the longitudinal axis of the ski, and a second part mounted in the binding and movable relative to the first part; this second part cooperate, through a system of ramps, with the boot-retaining means to oppose the lifting of the boot.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
229 words
A safety binding for skis which releases at least laterally and comprises: a vertical pivot integral with a base secured to the ski; a binding rotating upon the pivot and carrying means for retaining the boot; a system for locking said retaining means, said system being mounted in the binding and ensuring that the boot is maintained in a specific position upon the ski, said locking system comprising at least one resilient element and opposing a vertical retention force and a lateral retention force, respectively, to the vertical lift and lateral displacement of the boot, said resilient element being preset to allow the boot to be released when subjected to predetermined stresses in the plane of the ski; and a compensating mechanism acting upon said locking system, in order to cause the lateral retention force applied to the boot to vary inversely to the vertical retention force, said compensating mechanism including: a first part mounted to pivot about an axis at right angles to the longitudinal axis of the ski and located between the kinematic chain consisting of the resilient element and a reaction part which is fixed in relation to the ski; and a second part mounted in the binding so as to be mobile in relation to the first part, and cooperating, through a system of ramps, with the boot-retaining means opposing the lifting of said boot.
Claim 2
Dependent Claim
229 words
A safety binding for skis which releases at least laterally and comprises: a vertical pivot integral with a base secured to the ski; a binding rotating upon the pivot and carrying means for retaining the boot; a system for locking said retaining means, said system being mounted in the binding and ensuring that the boot is maintained in a specific position upon the ski, said locking system comprising at least one resilient element and opposing a vertical retention force and a lateral retention force, respectively, to the vertical lift and lateral displacement of the boot, said resilient element being preset to allow the boot to be released when subjected to predetermined stresses in the plane of the ski; and a compensating mechanism acting upon said locking system, in order to cause the lateral retention force applied to the boot to vary inversely to the vertical retention force, said compensating mechanism including: a first part mounted to pivot about an axis at right angles to the longitudinal axis of the ski and located between the kinematic chain consisting of the resilient element and a reaction part which is fixed in relation to the ski; and a second part mounted in the binding so as to be mobile in relation to the first part, and cooperating, through a system of ramps, with the boot-retaining means opposing the lifting of said boot.
Claim 3
Dependent Claim
21 words
A binding according to claim 1, the transverse axis upon which is mounted said first part is accommodated in the binding.
Claim 4
Dependent Claim
20 words
A binding according to claim 1, wherein said second part is mounted to pivot in relation to said first part.
Claim 5
Dependent Claim
23 words
A binding according to claim 1, wherein the stationary reaction part is integral with the fixed vertical pivot about which the binding rotates.
Claim 6
Dependent Claim
20 words
A binding according to claim 4, wherein said reaction part consists of a vertical flat arranged upon the fixed pivot.
Claim 7
Dependent Claim
20 words
A binding according to claim 4, wherein said reaction part consists of a curved profile arranged upon the fixed pivot.
Claim 8
Dependent Claim
105 words
A binding according to claim 6, wherein the first part of the compensating mechanism consists of a rocker pivoting about a horizontal axis in the binding and applied to the stationary reaction part by the resilient element of the locking system, in such a manner as to oppose the rotation of the binding; the second part of the compensating mechanism consists of a second rocker mounted to pivot upon the first rocker and caused, by the resilient element of the locking system, to besar against a cross member mounted in the sole-clamp and transferring to said second rocker the vertical forces applied to said sole-clamp.
Claim 9
Dependent Claim
32 words
A binding according to claim 7, wherein the second rocker is mounted to pivot on a seat in the first rocker, so that it may execute a rotary motion in relation thereto.
Claim 10
Dependent Claim
74 words
A binding according to claim 8, wherein the resilient system consists of a single spring, one end of which bears against the binding and the other end against the second rocker, the thrust of said spring being transferred to the first rocker through an area of contact between the rockers, the distance of which from the hinge axis of said first rocker varying as a function of the relative angular position of the rockers.
Claim 11
Dependent Claim
28 words
A binding according to claim 9, wherein the second rocker is provided with a ramp in its area of contact with the cross member mounted in the sole-clamp.
Claim 12
Dependent Claim
98 words
A binding according to claim 6, wherein the compensating mechanism consists of: a first rocker pivoting about a horizontal axis in the binding and caused to bear against the reaction part by the resilient locking system, in such a manner as to oppose the rotation of the binding about the pivot; and by a second rocker, also pivoting about a horizontal axis in the binding, the free end of the said rocker being designed to cooperate, under the action of the locking system, with the rear part of the sole-clamp which is in the form of a cam.
Claim 13
Dependent Claim
19 words
A binding according to claim 11, wherein the two rockers are mounted upon one and the same pivot axis.
Claim 14
Dependent Claim
38 words
A binding according to claim 12, wherein the resilient locking system consists of two springs bearing respectively, on the one hand on the binding and, on the other hand on the free end of one of the rockers.
Claim 15
Dependent Claim
53 words
A binding according to claim 13, wherein the first rocker has a support surface acting as a stop for the second rocker, in such a manner that when said rockers are bearing against each other, the load applied by the spring associated with said second rocker is transferred completely to the first rocker.
Claim 16
Dependent Claim
119 words
A binding according to claim 6, wherein the compensating mechanism consists of: a single rocker pivoting about a horizontal axis in the binding and urged towards the flat on the pivot by the resilient locking system bearing, on the one hand on said binding and, on the other hand on said rocker; and by a part mounted in a housing in the sole-clamp and adapted to move in relation thereto, said part being in constant contact, on the one hand, with a ramp on the free end of the rocker and, on the other hand, with the flat on the pivot, and being designed to transfer the loads between the sole-clamp, the rocker, and the flat on the pivot.
Claim 17
Dependent Claim
38 words
