Abstract
Abstract A ski boot having an ankle cuff which is movable relative to a lower shell about a transverse axis or the like which is provided at approximately ankle height on the ski boot. A support member is provided which cooperates with structure on the ski to limit the forward and/or the rearward movement of the ankle cuff relative to the lower shell. Generally, the support member cooperates between the ankle cuff and a component of the ski binding effecting securement of the ski boot to the ski. The components of the support member can be separate from the ski boot construction, namely part of the ski binding components or the support member can be an integral part of the ski boot construction having structure thereon which cooperates with an element fixedly secured to the ski.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
166 words
The combination of a ski boot and a ski binding for releasably securing said boot to a ski, said ski boot having a lower shell with a raised rear wall 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 fixedly secured to said ski and engaging the heel portion of said ski boot to hold said heel portion to a ski, 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 is wholly separate from said ski boot and 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.
Claim 2
Dependent Claim
166 words
The combination of a ski boot and a ski binding for releasably securing said boot to a ski, said ski boot having a lower shell with a raised rear wall 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 fixedly secured to said ski and engaging the heel portion of said ski boot to hold said heel portion to a ski, 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 is wholly separate from said ski boot and 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.
Claim 3
Dependent Claim
66 words
The improved combination according to claim 1, wherein said second surface is located at a fixed height above the upper surface of said ski, and wherein said heel portion of said ski boot has a design which permits, when the boot is used for walking, said projection means to move unhindered and limited only by the original design of the pivoting capability of said ankle cuff.
Claim 4
Dependent Claim
102 words
The improved combination according to claim 1, wherein said ankle cuff has a plurality of vertically spaced recesses along the rearwardly facing side thereof, wherein said projection means comprises a reinforcing member pivotally secured to said pivot axis and being pivotal independently of said ankle cuff, said reinforcing member including a reinforcing insert which, in cross section, has an approximately inverted L-shape, the longer arm of which forms the rearward inner part of said reinforcing member, and the shorter arm of which is received into one of said recesses to fix the position of said reinforcing member relative to said ankle cuff.
Claim 5
Dependent Claim
33 words
The improved combination according to claim 3, including fastener means for additionally fixing said reinforcing member relative to said ankle cuff; and wherein said second surface is a surface on said heel holder.
Claim 6
Dependent Claim
99 words
The improved combination according to claim 1, wherein said projection means defines a hollow housing having a polygon-shaped recess therein, wherein said first surface is provided on a support member movable in said housing against the force of a spring, said spring being located in said housing so that one of its ends engages said support member and the other end engages the bottom of said recess, and wherein said support member has along the rear side thereof saw-toothlike teeth, said housing having a catch mechanism engaged with selected teeth to fix the position thereof relative to said housing.
Claim 7
Dependent Claim
57 words
The improved combination according to claim 15, wherein said projection means includes a fixed stop secured to said ankle cuff and, in the downhill position, engaging a bar pivotally secured to a plate held fixedly on said ski by said heel holder, said first surface being on said fixed stop, said second surface being on said bar.
Claim 8
Dependent Claim
46 words
The improved combination according to claim 1, wherein said second means includes a support member consisting of two elongated parts movable lengthwise relative to one another and means for securing said parts in different positions to vary the spacing of said second surface from said ski.
Claim 9
Dependent Claim
22 words
The improved combination according to claim 7, wherein said second surface on said support member has a coating of elastic material thereon.
Claim 10
Dependent Claim
88 words
The improved combination according to claim 1, wherein said ankle cuff has an opening therein, wherein said second means includes a support member and wherein said support member is secured to said heel holder and has a support head thereon extending through said opening in said ankle cuff into a recess on said raised rear wall, said first surface being defined by an edge segment of said opening in said ankle cuff, said second surface being defined by a segment on said support head opposing said edge segment.
Claim 11
Dependent Claim
65 words
The improved combination according to claim 1, including a sole plate positioned between said ski boot and said ski, said heel holder being mounted on said sole plate and further including a front toe holder, said heel holder having said second means thereon engaging said raised rear wall of said lower shell of said ski boot and forming said second surface for said projection means.
Claim 12
Dependent Claim
35 words
The improved combination according to claim 10, wherein said second means engages, in addition to said raised rear wall of said lower shell, said ankle cuff to lock said ankle cuff to said lower shell.
Claim 13
Dependent Claim
39 words
The improved combination according to claim 1, including a support element fixed with respect to said ski and located adjacent the toe of said ski boot for limiting the forward extent of said pivotal movement of said ankle cuff.
Claim 14
Dependent Claim

The improved combination according to claim 12, including a front toe holder and wherein said support element consists of an extension which is secured to said front toe holder and terminates at the free end thereof in an insert member and wherein said ski boot has at least two spaced buckles thereon, said insert member being received in the space between said buckles.
Claim 15
Dependent Claim
32 words
The improved combination according to claim 13, wherein said boot buckles include adjustment means for permitting an adjustment of the position thereof relative to said ski boot to vary the spacing therebetween.
Claim 16
Dependent Claim
41 words
The improved combination according to claim 1, wherein said means includes a support member movably supported on said ski, and wherein said second surface is on said support member and is defined by a roller rotatably mounted on said support member.
