Abstract
Abstract A ski-boot, molded from rubber or plastics, in which the neck portion of the upper is bendable relative to the foot portion. A connection, such as a piston and cylinder arrangement, prevents relative bending of the two portions from an initially chosen infinitely adjustable fixed position until the bending force exceeds a pre-set value. Any subsequent bending is limited by adjustable stops, and the pre-set value of bending force can also be adjusted.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
A ski-boot comprising, in combination: a. a molded upper; b. a foot portion of said upper; c. a neck portion bendable relative to the foot portion about a transverse axis in the vicinity of the ankle of a wearer of the boot; d. connecting means connecting the neck portion to the foot portion to fix the relative position of said neck portion and said foot portion against forward or rearward pivotal movement; e. infinitely variable adjusting means controlling said relative position between upper and lower limits; and f. adjustable release means in said connecting means for releasing said neck portion and foot portion for permitting forward or rearward pivotal movement of the neck and foot portions in response to the application of a predetermined force in accordance with the state of adjustment of said adjustable release means.
Claim 2
Dependent Claim
137 words
A ski-boot comprising, in combination: a. a molded upper; b. a foot portion of said upper; c. a neck portion bendable relative to the foot portion about a transverse axis in the vicinity of the ankle of a wearer of the boot; d. connecting means connecting the neck portion to the foot portion to fix the relative position of said neck portion and said foot portion against forward or rearward pivotal movement; e. infinitely variable adjusting means controlling said relative position between upper and lower limits; and f. adjustable release means in said connecting means for releasing said neck portion and foot portion for permitting forward or rearward pivotal movement of the neck and foot portions in response to the application of a predetermined force in accordance with the state of adjustment of said adjustable release means.
Claim 3
Dependent Claim
33 words
A ski-boot according to claim 1 wherein said connecting means includes stop means effective to limit relative movement between said neck portion and said foot portion when said predetermined force has been exceeded.
Claim 4
Dependent Claim
50 words
A ski-boot as claimed in claim 1 wherein said adjustable release means includes a cylinder connected to one of said portions, a piston slidable in said cylinder and connected to the other of said portions and means for adjusting the force required to move said piston relative to said cylinder.
Claim 5
Dependent Claim
16 words
A ski-boot as claimed in claim 3, wherein said piston comprises a plug of deformable material.
Claim 6
Dependent Claim
72 words
