Abstract
Abstract An apparatus located between a ski and a binding mounted thereon, including at least one shock absorption buffer positioned partially in a seat cut-away with respect to the most elevated portion of the ski and extending beyond this portion at rest. The comfort of the skier and the steering of the skis is enhanced without raising the binding with respect to the ski by utilizing the natural cut-aways. The cut-aways are created during the manufacture of the ski or are provided in the thickness of the ski after manufacture. The buffer is then installed within the seat thus cut-away, rather than merely installed on the upper surface of the ski. The buffer is preferably made of viscoelastic material.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
112 words
A shock and vibration absorption apparatus to be located between a ski and a binding of a shoe or boot of a skier, comprising at least one shock and vibration absorption buffer at least partially positioned in at least one seat located at a portion of said ski where said binding is to be attached, and extending beyond the height of said portion, wherein said apparatus is to be used with a ski having a longitudinally extending central projection and wherein said at least one seat comprises two lateral seats provided on both sides of said longitudinally extending central projection of said ski to each receive a shock and vibration absorption buffer.
Claim 2
Dependent Claim
112 words
A shock and vibration absorption apparatus to be located between a ski and a binding of a shoe or boot of a skier, comprising at least one shock and vibration absorption buffer at least partially positioned in at least one seat located at a portion of said ski where said binding is to be attached, and extending beyond the height of said portion, wherein said apparatus is to be used with a ski having a longitudinally extending central projection and wherein said at least one seat comprises two lateral seats provided on both sides of said longitudinally extending central projection of said ski to each receive a shock and vibration absorption buffer.
Claim 3
Dependent Claim
20 words
Apparatus according to claim 1, wherein each said shock and vibration absorption buffer is constituted by a viscoelastic material block.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 2, wherein said block is at least on one surface fastened to a metallic plate.
Claim 5
Dependent Claim
21 words
Apparatus according to claim 2, wherein the viscoelastic material has a shock absorption coefficient which is at most equal to 1.2.
Claim 6
Dependent Claim
18 words
Apparatus according to claim 2, wherein the viscoelastic material has a hardness between 35 and 65 Shore A.
Claim 7
Dependent Claim
13 words
Apparatus according to claim 2, wherein the viscoelastic material is made of polyurethane.
Claim 8
Dependent Claim
13 words
Apparatus according to claim 2, wherein the viscoelastic material is made of polyisoprene.
Claim 9
Dependent Claim
13 words
Apparatus according to claim 2, wherein the viscoelastic material is made of isobutylene.
Claim 10
Dependent Claim
13 words
Apparatus according to claim 2, wherein the viscoelastic material is made of polyisoxylane.
Claim 11
Dependent Claim
26 words
Apparatus according to claim 1, wherein each shock and vibration absorption buffer is fixed to said ski in its seat and to said binding by gluing.
Claim 12
Dependent Claim
39 words
Apparatus according to claim 1, in combination with a ski, further comprising a plate attached to a lower portion of each of said at least one shock and vibration absorption buffer, wherein said plate is embedded within said ski.
Claim 13
Dependent Claim
28 words
The apparatus according to claim 1, wherein said at least one shock and vibration absorption buffer comprises a material having a substantially uniform shock and vibration absorption capacity.
Claim 14
Dependent Claim
26 words
Apparatus according to claim 1, wherein each shock and vibration absorption buffer is fixed to said skit in its seat and to said binding by screwing.
Claim 15
Dependent Claim
50 words
Apparatus according to claim 1, wherein each said seat has a predetermined dimension, and wherein each said shock and vibration absorption buffer comprises a corresponding dimension which is less than said predetermined dimension to thereby permit said shock and vibration buffer to have relatively free play within its respective seat.
Claim 16
Dependent Claim
10 words
Apparatus according to claim 1, in combination with said binding.
Claim 17
Dependent Claim
10 words
Apparatus according to claim 1, in combination with said ski.
Claim 18
Dependent Claim
13 words
Apparatus according to claim 1, in combination with said binding and said ski.
Claim 19
Dependent Claim
24 words
Apparatus according to claim 1, wherein said buffer is adapted to enable the binding to move vertically, laterally, and longitudinally relative to the ski.
Claim 20
Dependent Claim
101 words
A shock and vibration absorption apparatus to be located between a ski and a binding of a shoe or boot of a skier comprising at least one shock and vibration absorption buffer at least partially positioned in at least one seat located at a portion of said ski where said binding is to be attached, and extending beyond the height of said portion, wherein said at least one shock and vibration absorption buffer comprises an upper surface and a lower surface and wherein said upper surface, in its entirety, is movable perpendicularly toward said lower surface to absorb shocks and vibrations.
Claim 21
Dependent Claim
101 words
A shock and vibration absorption apparatus to be located between a ski and a binding of a shoe or boot of a skier comprising at least one shock and vibration absorption buffer at least partially positioned in at least one seat located at a portion of said ski where said binding is to be attached, and extending beyond the height of said portion, wherein said at least one shock and vibration absorption buffer comprises an upper surface and a lower surface and wherein said upper surface, in its entirety, is movable perpendicularly toward said lower surface to absorb shocks and vibrations.
