Ski binding and ski therefor

Abstract

The invention relates to a ski binding that includes an elastic buffer adapted to exert a return force on a boot when the boot heel is raised from the upper surface of the ski. The elastic buffer has a support surface adapted to come into abutment against the bottom of the sole of the ski boot, the support surface forming an angle with a plane substantially parallel to the upper surface of the ski ranging between 0° and 80°. The invention also relates to a ski in combination with the aforementioned binding.

1 . A ski binding for binding a boot to a ski, said ski binding comprising:
 an elastic buffer constructed and arranged, relative to the ski when a front of the boot is connected to the binding and the binding is attached to the ski, to exert a return force on the boot when a heel of the boot is raised from an upper surface of the ski;   the elastic buffer having a support surface constructed and arranged to engage in abutment against a bottom of a sole of the ski boot;   the support surface forming an angle with a plane substantially parallel to the upper surface of the ski in a range between 0° and 80°.   
     
     
         2 . A ski binding according to  claim 1 , wherein:
 the angle between the support surface and the plane substantially parallel to the upper surface of the ski is in a range between 0° and 40°.   
     
     
         3 . A ski binding according to  claim 1 , further comprising:
 a retaining device including a fixed jaw and a movable jaw;   the movable jaw being structured and arranged to move, relative to the fixed jaw, between an open binding position and a closed binding position;   in the closed position of the binding, the fixed jaw being spaced from a rear edge of the support surface by a distance of less than 10 millimeters.   
     
     
         4 . A ski binding according to  claim 1 , wherein:
 the elastic buffer comprises a thermoplastic material having a hardness ranging between 35 and 95 Shore A.   
     
     
         5 . A ski binding according to  claim 1 , wherein:
 the elastic buffer has a shape of an accordion.   
     
     
         6 . A ski binding according to  claim 1 , further comprising:
 a plate comprising a longitudinal boot-guiding rib structured and arranged to be complementary with a groove in the sole of the boot to guide the boot during movement of the boot during raising and lowering of the heel of the boot relative to the ski.   
     
     
         7 . A ski binding according to  claim 6 , wherein:
 the guiding rib is sectioned by at least one transverse groove.   
     
     
         8 . A ski binding according to  claim 3 , further comprising:
 a plate comprising a longitudinal boot-guiding rib;   said guiding rib being sectioned by means of at least one transverse groove;   said guiding rib being forwardly extended by means of the fixed jaw.   
     
     
         9 . A ski binding according to  claim 1 , wherein:
 the elastic buffer comprises a deformation portion having a pyramidal shape.   
     
     
         10 . An assembly for skiing comprising:
 a ski; and   a binding for binding a boot to the ski, said binding comprising:
 an elastic buffer constructed and arranged, relative to the ski when a front of the boot is connected to the binding and the binding is attached to the ski, to exert a return force on the boot when a heel of the boot is raised from an upper surface of the ski; 
 the elastic buffer having a support surface constructed and arranged to engage in abutment against a bottom of a sole of the ski boot; 
 the support surface forming an angle with a plane substantially parallel to the upper surface of the ski in a range between 0° and 80°.
