Abstract
Abstract A boot heel holding member of a ski safety binding is pivotally mounted and urged by a spring either downwardly towards an operative boot holding position, or upwardly towards an inoperative boot releasing position. A second pivotally mounted member can be releasably locked in a fixed position by adjustable locking means such as a spring-urged ball engaging in a recess. One-direction movement means act between the holding and second members so that when the second member is locked in position the holding member can move towards the operative position under the action of the spring, whilst for movement of the first member towards the inoperative position the holding member is angularly locked with the second member. The binding can thus automatically adapt to different heel thickness and can accomodate a layer of snow the maximum thickness of which is independent of the spring strength. The one-direction movement means can be a pawl cooperating with a locking surface or any free-wheel mechanism.

Claim 8
Dependent Claim
138 words
A binding according to claim 4, including a third member pivotally mounted about said common axis, said third member acting as a support for at least a part of a sole of a boot held by the binding, and means for angularly interlocking the first and third members such that movement of the first member from the operative position towards the inoperative position causes raising of the third member, and lowering of the third member causes movement of the first member from the inoperative position towards the operative position, wherein when the third member is lowered while the second member is away from the first position, a part of the third member engages with said lever to move the second member towards the first position and to urge the pawl towards the surface integral with the first member.
Claim 9
Dependent Claim
52 words
A binding according to claim 4, wherein the second member comprises a generally hollow cylindrical part having an inner cylindrical surface, said pawl being pivotally mounted on a part of the first member inside said hollow cylindrical part, the one-direction movement device comprising means for urging the pawl against said cylindrical surface.
