Abstract
Abstract Interface device between a boot and a ski designed to modify the natural distribution of the ski on the snow along the line of a vertical thrust force which at least one part of the boot generates on the ski. The device comprises a vertically-mobile sensing device (11) which absorbs the vertical stresses from the boot, a rocker (16), and a transmission device (21) which transforms the vertical stresses of the boot into a forward-directed force of thrust. The transmission device (21) is connected to the base (25) in a zone raised off the upper ski surface. The transmission device (21) is connected to a transmission element (31) which travels longitudinally in relation to a stationary element (30), and a deformable means (38) blocks relative motion of the transmission element (31) in relation to the stationary element (30).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
232 words
An interface device between a boot and a ski intended to modify the natural pressure distribution of the ski on a sliding surface of the ski in the direction of a vertical thrust force which at least one portion of the boot exerts on the ski, said boot being held in place on the ski by a front binding (3) and a rear binding (4), each of said bindings being assembled to the ski by respective bases (12,14), said interface device comprising a sensor device (11) intended to absorb stresses between said boot and said ski, linkage means (16) for transforming said stresses into at least one force of thrust directed approximately longitudinally to at least one of the ends of the ski, and a transmission device (21) intended to transmit the longitudinal force to said base (25) of said front binding (3) on a side facing one end of said ski, said transmission device (21) being connected to said base of said front binding in a zone raised off an upper surface of the ski, wherein said transmission device (21) is connected to a longitudinally movable transmission element (31, 50, 71) of said base of said front binding, and a deformable element (38, 53, 73) which opposes the relative motion of said movable transmission element in relation to the upper ski surface and longitudinally in the direction of the longitudinal force.
Claim 2
Dependent Claim
232 words
An interface device between a boot and a ski intended to modify the natural pressure distribution of the ski on a sliding surface of the ski in the direction of a vertical thrust force which at least one portion of the boot exerts on the ski, said boot being held in place on the ski by a front binding (3) and a rear binding (4), each of said bindings being assembled to the ski by respective bases (12,14), said interface device comprising a sensor device (11) intended to absorb stresses between said boot and said ski, linkage means (16) for transforming said stresses into at least one force of thrust directed approximately longitudinally to at least one of the ends of the ski, and a transmission device (21) intended to transmit the longitudinal force to said base (25) of said front binding (3) on a side facing one end of said ski, said transmission device (21) being connected to said base of said front binding in a zone raised off an upper surface of the ski, wherein said transmission device (21) is connected to a longitudinally movable transmission element (31, 50, 71) of said base of said front binding, and a deformable element (38, 53, 73) which opposes the relative motion of said movable transmission element in relation to the upper ski surface and longitudinally in the direction of the longitudinal force.
Claim 3
Dependent Claim

Device according to claim 1, wherein said deformable element (38) comprises at least one spring (35, 36, 37) resting, at one of its ends, against a stationary element (30) belonging to said base (25) of said front binding, and at the other end, against the mobile transmission element (31, 71).
Claim 4
Dependent Claim
46 words
Device according to claim 2, wherein the pretensioning of said deformable element (38) is calibrated and said linkage element (31, 71) travels in relation to said stationary element (30) only when the force transmitted to it is greater than the calibrated force of said deformable element.
Claim 5
Dependent Claim
21 words
Device according to claim 3, wherein said calibrated force of said deformable element is between 30 and 80 kilograms of force.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
49 words
Device according to claim 5, wherein said stationary element (30) belonging to said base (25) is extended beneath said platform (52) by a tongue (69) pressed against the upper ski surface and said block of elastically deformable material (43) is inserted between said platform (52) and said tongue (69).
Claim 8
Dependent Claim
55 words
Device according to claim 1, wherein said mobile transmission element (50, 71) is extended beyond the binding by a platform (52, 72) raised off the upper ski surface and said deformable element is a block of deformable material (53, 73) mounted in a sandwich configuration between said platform (52, 72) and the upper ski surface.
Claim 9
Dependent Claim
