Alpine ski

Abstract

A ski adapted for the practice of alpine skiing includes a front portion, a rear portion, and a central portion, the central portion being adapted to receive an assembly for binding a boot to the ski, which is inserted between the front portion and the rear portion. The front portion includes a maximum width having a value ranging between 135 mm and 165 mm, and the difference between the maximum width value of the front portion and the maximum width value of the rear portion is greater than 25 mm and less than 55 mm. The rear portion can include a maximum width value ranging between 90 mm and 130 mm, and the central portion can include a smaller width value ranging between 60 mm and 130 mm.

1 . A ski structured and arranged for the practice of alpine skiing, said ski comprising:
 a front portion;   a rear portion;   a central portion structured and arranged to receive an assembly for binding a boot to the ski, such assembly to be mounted to the ski between the front portion and the rear portion;   the front portion of the ski comprises a portion of greater width, including a maximum width value (S) ranging between 135 mm and 165 mm;   a difference between the maximum width value (S) of the front portion and a maximum width value (T) of the rear portion is greater than 25 mm.   
     
     
         2 . A ski according to  claim 1 , wherein:
 the central portion comprises a line of smallest width and a marking of the boot center (MC) corresponding to a zone in which the binding assembly is to be centered;   a distance (LC) separating the line of smallest width and the marking of the boot center is greater than 150 mm.   
     
     
         3 . A ski according to  claim 1 , wherein:
 the rear portion comprises a portion of greater width, including the maximum width value (T) ranging between 90 mm and 130 mm.   
     
     
         4 . A ski according to  claim 1 , wherein:
 a smallest width of the central portion ( 4 ) has a value (C) ranging between 60 mm and 130 mm.   
     
     
         5 . A ski according to  claim 1 , wherein:
 the difference between the maximum width value (S) and the maximum width value (T) is greater than 32 mm.   
     
     
         6 . A ski according to  claim 1 , wherein:
 the difference between the maximum width value (S) and the maximum width value (T) ranges between 32 mm and 55 mm.   
     
     
         7 . A ski according to  claim 1 , wherein:
 the maximum width value (S) ranges between 140 mm and 160 mm.   
     
     
         8 . A ski according to  claim 2 , wherein:
 the distance (LC) is greater than 180 mm.   
     
     
         9 . A ski according to  claim 1 , wherein:
 the shovel has a length (Ls) ranging between 150 and 320 mm.   
     
     
         10 . A ski according to  claim 9 , wherein:
 the shovel has a length (Ls) ranging between 160 and 300 mm.   
     
     
         11 . A ski according to  claim 1 , wherein:
 a width (P) of the ski, measured at a distance of 30 mm from a front end of the ski, is less than 60% of the maximum width value (S) of the front portion: P<0.6×S.   
     
     
         12 . A ski according to  claim 11 , wherein:
 a width (P) of the ski, measured at a distance of 30 mm from a front end of the ski, is less than 50% of the maximum width value (S) of the front portion: P<0.5×S.   
     
     
         13 . A ski according to  claim 4 , wherein:
 the line of the smallest width (C) of the central portion and the line of the maximum width value (T) of the rear portion are merged.   
     
     
         14 . A ski according to  claim 4 , wherein:
 a distance (LB) separating the maximum width value (T) of the rear portion and the smallest width value (C) of the central portion is zero.
