ein sehr gutes Patent, was wir ähnlich für das Projekt Sidewinder benutzen.
Allerdings hat hier Rossignol nicht komplett weitergemacht.
Denn einige Grundelemente fehlen.
Also: hier optimieren, aufsetzen , dann bauen und anschliessend Probefahren.

The invention relates to a snow gliding board (1) having a sidecut (2)
that widens from the middle area (3)
of the board towards at least one of its ends to a point of maximum width (4)
and of which the structure
includes a reinforcing fiber mat (10)
comprising yarns (11)
that extend in the longitudinal direction of the board.
It is characterised in that the number of yarns (11) per unit of length, measured across the board, varies from the middle area (3) towards the point of maximum width (4) of the board.
. A snow gliding board (1) having a sidecut that widens from a middle area (3) of the board towards at least one of its ends to a point of maximum width (4) , and having a structure which includes a reinforcing fibre mat (10) comprising a plurality of yarns (11) that extend in the longitudinal direction of the board,
wherein the number of yarns (11) per unit of width of the board, varies from the middle area (3) towards the point of maximum width (4) of the board.
2. A gliding board as claimed inclaim 1, characterised in that the number of yarns per unit of width reaches it maximum value in the vicinity of areas (72) where bindings are mounted.
3. A gliding board as claimed inclaim 1, characterised in that the number of yarns per unit of width increases from the middle area towards areas (72) where bindings are mounted and then diminishes beyond this point towards the point of maximum width (74) of the board.
4. A gliding board as claimed inclaim 1, characterised in that the number of yarns per unit of width measured in the traverse direction reduces as the sidecut of the board widens.
5. A gliding board as claimed inclaim 1, characterised in that the fibre mat (10) extends over the entire width of the board.
6. A gliding board as claimed inclaim 1, characterised in that the number of yarns measured over the entire length of the fibre mat is constant over its entire length.
7. A gliding board as claimed inclaim 1, characterised in that the reinforcing fibre mat extends over only part of the length of the board.
8. A gliding board as claimed inclaim 1, characterised in that the board comprises several reinforcing fibre mats placed one above the other or juxtaposed.
9. A gliding board as claimed inclaim 1, characterised in that the fibre mat (25) has openings.
10. A gliding board as claimed inclaim 9, characterised in that the openings (26) are made by cutting out and removing material.
11. A gliding board as claimed inclaim 9, characterised in that the openings (29) are made by spreading apart the yarns (27,28).
12. A gliding board as claimed inclaim 1, characterised in that the fibre mat comprises at least a first layer formed by a mat of yarns (31) extending in the longitudinal direction of the board and a second support layer (32) having a structure capable of deformation in the transverse direction of the board.
13. A gliding board as claimed inclaim 1, characterised in that the fibre mat comprises a plurality of yarns (41) extending in the longitudinal direction of the board woven with a plurality of perpendicular yarns (42) that have the ability to stretch.
14. A gliding board as claimed inclaim 1, characterised in that the yarns (51,52) of the reinforcing fibre mat have different properties, in terms of the nature or size thereof, over the width of said mat.
15. A snow gliding board (1) having a sidecut that widens from a middle area (3) of the board towards at least one of its ends to a point of maximum width (4), and having a structure which includes a reinforcing stiffner (10) comprising a plurality of yarns (11) that extend in the longitudinal direction of the board, wherein
the distance between adjacent longitudinally extending yarns increases from a minimum distance at said middle area (3) to a maximum at the point of maximum width (4) of the board.
16. A gliding board as claimed inclaim 15, characterised in that the number of yarns per unit of width reaches it maximum value in the vicinity of areas (72) where bindings are mounted
