Claim 4

The ski as claimed in claim 1, wherein the layer of the sheet has lateral edges drawn in the form of a curve and which converge to form terminal points from the broadest middle zone with a continuous decrease in breadth of the layer or sheet towards the ends.

Claim 5

A ski comprising a ski body, a layer or sheet attached to an uppermost surface of said ski body, said layer or sheet being adapted to damp vibrations and being made of a viscoelastic material, said layer or sheet extending continuously from a zone of a shovel of said ski body to an end zone of said ski body, said layer or sheet extending from a zone in front of said shovel to said end zone, extending to a distance from an end of said ski body equal to a distance the layer or sheet extends from a ski tip of the ski body, said layer or sheet having generally sinusoidal edges such that a middle broad zone widens following waists towards the ends.

Claim 6

A ski comprising a ski body, a layer or sheet attached to an uppermost surface of said ski body, said layer or sheet being adapted to damp vibrations and being made of a viscoelastic material, said layer or sheet extending continuously from a zone of a shovel of said ski body to an end zone of said ski body, said layer or sheet extending from a zone in front of said shovel to said end zone, extending to a distance from an end of said ski body equal to a distance the layer or sheet extends from a ski tip of the ski body, said layer or sheet having generally sinusoidal edges such that a middle broad zone widens following waists towards the ends.

Claim 7

The ski as claimed in claim 4 wherein the layer or the sheet has a multi-ply structure.

Claim 8

The ski as claimed in claim 5, wherein the plies are selected from the group including plastic, fiber reinforced plastic and metal.

Claim 9

The ski as claimed in claim 6 wherein the layer or sheet is arranged symmetrically to the median line of the ski.

Claim 10

The ski as claimed in claim 6 wherein the zones of the layer or sheet on the two sides of the median line consist of materials of different stiffness.

Claim 11

The ski as claimed in claim 8, wherein ends and edges of the layer or sheet are rounded to steplessly merge with the uppermost surface of the ski body.

Claim 12

A ski with a torsionally stiff inner edge and a torsionally soft outer edge as claimed in claim 8, wherein the inner zone of the layer or sheet is selected from the group of stiff and hard materials and the outer zone is selected from the group of soft and elastic materials.

Claim 13

The ski as claimed in claim 10, wherein the layer or the sheet is adhesively bonded to the ski.

Claim 14

The ski as claimed in claim 10, wherein that the layer or the sheet is attached to the ski by bolts or screws having heads, the shanks of same fitting through slots aligned with the longitudinal direction of the ski.

Claim 15

The ski as claimed in claim 12, characterized in that the slots are arranged in two rows which are parallel to each other.

Claim 16

A ski comprising: a ski body, a layer or sheet attached to an uppermost surface of said ski body, said layer or sheet being adapted to damp vibrations and being made of a viscoelastic material, said layer or sheet extending continuously from a zone of a shovel of said ski body to an end zone of said ski body, said layer or sheet extending from a zone in front of said shovel to said end zone, extending to a distance from an end of said ski body equal to a distance, the layer or sheet extends from a ski tip of said ski body, said layer or sheet having generally sinusoidal edges such that a middle broader zone widens following waists towards the ends, said layer or the sheet has a multi-ply structure, and plies of said multi-ply structure are selected from the group of plastic, fiber reinforced plastic, and metal.

Claim 17

A ski comprising: a ski body, a layer or sheet attached to an uppermost surface of said ski body, said layer or sheet being adapted to damp vibrations and being made of a viscoelastic material, said layer or sheet extending continuously from a zone of a shovel of said ski body to an end zone of said ski body, said layer or sheet extending from a zone in front of said shovel to said end zone, extending to a distance from an end of said ski body equal to a distance, the layer or sheet extends from a ski tip of said ski body, said layer or sheet having generally sinusoidal edges such that a middle broader zone widens following waists towards the ends, said layer or the sheet has a multi-ply structure, and plies of said multi-ply structure are selected from the group of plastic, fiber reinforced plastic, and metal.

Claim 18

The ski as claimed in claim 14, wherein the layer or sheet is arranged symmetrically to a median line of the ski.

Claim 19

The ski as claimed in claim 18, wherein the layer or the sheet is arranged asymmetrically to a median line of the ski.

Claim 20

The ski as claimed in claim 14, wherein zones of the layer or sheet on two sides of a median line consist of materials of different stiffness.

Claim 21

The ski as claimed in claim 14, wherein ends and edges of the layer or sheet are rounded to steplessly merge with the uppermost surface of the ski body.

Claim 22

A ski with a torsionally stiff inner edge and a torsionally soft outer edge as claimed in claim 17, wherein an inner zone of the layer or sheet is selected from the group including stiff and hard materials and the outer zone is selected from the group including soft and elastic materials.

Claim 23
