Cross-country ski

Abstract

Cross-country ski ( 1 ) having a tip ( 4 ) curved upward, extending beyond the front contact line ( 2 ), wherein the projection of the side line of the tip ( 4 ) of the ski over a horizontal plane has an inflexion point ( 6, 7 ) located forward of the front contact line ( 2 ), at least on one side of the ski.

1 . A cross-country ski ( 1 ) having a tip ( 4 ) curved upward, extending beyond the front contact line ( 2 ), wherein the projection of the side line of the tip ( 4 ) of the ski over a horizontal plane H has an inflexion point ( 6 ,  7 ) located forward of the front contact line ( 2 ), at least on one side of the ski.  
     
     
         2 . The ski as claimed in  claim 1 , wherein the projection of the side line of the tip ( 4 ) of the ski over a horizontal plane has two inflection points ( 6 ,  7 ) located forward of the front contact line, on each side of the ski.  
     
     
         3 . The ski as claimed in  claim 2 , which is symmetrical relative to its median longitudinal plane, at least in its tip zone.  
     
     
         4 . The ski as claimed in  claim 3 , wherein the width l of the tip ( 4 ) measured midway between the end ( 5 ) of the tip ( 4 ) and the front contact line ( 2 ) is between 40 and 8%, preferably between 50 and 75%, of the width L measured in the region of the front contact line  2 .
