Abstract
Abstract A safety ski binding having a reinforcing member on a ski boot, which ski boot has a shaft portion which is pivotal about a transverse axis. The reinforcing member has a shoulder thereon which is engageable with a removable support to limit the backward pivoting movement of the shaft portion but permit a desired amount of frontward movement. A lever is provided which is movable into and out of supporting engagement with the shoulder to facilitate entry of the ski boot into the ski binding.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
176 words
In a combination of a ski boot and a ski binding, said ski boot having a lower shell and an ankle cuff pivotally secured to said lower shell to allow pivotal movement of said ankle cuff about a pivot axis in response to shifts in the weight of an individual using said ski boot, said ski binding including at least a heel holder engaging the heel portion of said ski boot to hold said heel portion to a ski, the improvement comprising wherein said ankle cuff has projection means extending rearwardly therefrom and includes first means thereon defining a downwardly facing first surface and wherein said heel holder includes second means defining an upwardly facing second surface, said first surface directly engaging said second surface to limit the amount of pivotal movement of said ankle cuff to the rear of said lower shell, support means for supporting said second means for movement toward and away from said heel portion of said ski boot and resilient means for resiliently urging said second means toward said ski boot.
Claim 2
Dependent Claim
176 words
In a combination of a ski boot and a ski binding, said ski boot having a lower shell and an ankle cuff pivotally secured to said lower shell to allow pivotal movement of said ankle cuff about a pivot axis in response to shifts in the weight of an individual using said ski boot, said ski binding including at least a heel holder engaging the heel portion of said ski boot to hold said heel portion to a ski, the improvement comprising wherein said ankle cuff has projection means extending rearwardly therefrom and includes first means thereon defining a downwardly facing first surface and wherein said heel holder includes second means defining an upwardly facing second surface, said first surface directly engaging said second surface to limit the amount of pivotal movement of said ankle cuff to the rear of said lower shell, support means for supporting said second means for movement toward and away from said heel portion of said ski boot and resilient means for resiliently urging said second means toward said ski boot.
Claim 3
Dependent Claim
33 words
The improved combination according to claim 1, wherein said projection means includes a metal fitting mounted on said ankle cuff and movable therewith and wherein said metal fitting has said first surface thereon.
Claim 4
Dependent Claim
18 words
The improved combination according to claim 2, wherein said metal fitting is fixedly secured to said ankle cuff.
Claim 5
Dependent Claim
38 words
The improved combination according to claim 1, wherein said second means includes a bar and wherein said support means includes a hinged joint with an axis extending laterally of said ski for supporting said bar for pivotal movement.
Claim 6
Dependent Claim
27 words
The improved combination according to claim 4, wherein said projection means includes adjusting means for adjusting the position of said first surface relative to said ankle cuff.
Claim 7
Dependent Claim
19 words
The improved combination according to claim 5, wherein said projection means includes a support member made of elastic material.
Claim 8
Dependent Claim
39 words
The improved combination according to claim 6, wherein said support member is an intermediate layer, the physical characteristics of which, in particular its strength and elasticity, lend to the entire system a dampening which acts against the outer forces.
Claim 9
Dependent Claim
59 words
The improved combination according to claim 1 wherein said locking means includes a lock member and a spring, said lock member being movable against said spring, wherein said spring after release of said lock member holds said second means with respect to said projection means in the ready position spaced away from said ski boot and said projection means.
Claim 10
Dependent Claim
21 words
The improved combination according to claim 1, wherein said support means pivotally supports said second means for movement about an axis.
Claim 11
Dependent Claim
18 words
The improved combination according to claim 1, wherein said support means supports said second means for horizontal movement.
Claim 12
Dependent Claim
49 words
The improved combination according to claim 9, wherein said pivot axis lies at a distance behind the point of engagement on said first and second surfaces, which point of engagement effects a pulling in of said second means into a position adjacent said ski boot and said projection means.
Claim 13
Dependent Claim
32 words
The improved combination according to claim 8, wherein said second means includes a lever arm and wherein said lock member is an eccentric which cooperates with a shoulder on said lever arm.
Claim 14
Dependent Claim
