Snowboard binding

Abstract

A snowboard binding includes a base plate and a heel support attached directly or indirectly to this base plate so that it can pivot. Intermediate elements mount the heel support and can be adjusted in the longitudinal direction of the snowboard binding. Thus, the effective length of the snowboard binding can be adapted to the respective boot. Also, through different positioning of the intermediate elements, the heel support can be arranged diagonally relative to the longitudinal axis of the snowboard binding.

What is claimed: 
     
         1 . A device for retaining a foot or boot on a sports apparatus, the device comprising:
 a base plate extending lengthwise from a rear end to a front end and widthwise from a first side to a second side;   a heel support element and a pivot mechanism mounting the heel support element to pivot with respect to the base plate, the pivot mechanism comprising a first pivot support and a second pivot support;   an elongated element extending between the base plate and the heel support element to limit rearward pivot movement of the heel support element relative to the base plate, the elongated element having a first portion and a second portion, the first and second portions of the elongated element being connected to the base by a first and a second lower connection, respectively, the first and second lower connections being located in front of the first and second pivot supports; and   an adjustment mechanism to enable a modification of a longitudinal position of the heel support element with respect to the base plate.   
     
     
         2 . A device according to  claim 1 , wherein:
 the adjustment mechanism enables a predeterminate longitudinal displacement of the heel support element independent of the elongated element.   
     
     
         3 . A device according to  claim 1 , further comprising:
 a mechanism to enable a predeterminate displacement of the heel support element simultaneously with the elongated element.   
     
     
         4 . A device according to  claim 1 , wherein:
 the adjustment mechanism enables a predeterminate longitudinal displacement of the heel support element in an area of at least one of two transversely opposite sides of the heel support element.   
     
     
         5 . A device according to  claim 1 , further comprising:
 an upward element positioned at one of the sides of the base plate;   a displacement element mounted for longitudinal displacement with respect to the upward element, the displacement element connected to a fastening end of the heel support element; and   the adjustment mechanism comprising a structure to adjust the longitudinal position of the displacement element.   
     
     
         6 . A device according to  claim 1 , wherein:
 the device is a snowboard binding for retaining a snowboard boot on a snowboard.   
     
     
         7 . A device according to  claim 1 , further comprising:
 an assembly to mount the base plate to the sports apparatus.   
     
     
         8 . A device according to  claim 7 , wherein:
 the base plate comprises a through opening in a thickness of the base plate;   the assembly to mount the base plate to the sports apparatus comprises a disk adapted to be positioned within and to be engaged with a periphery of the opening of the base plate, and a plurality of screws adapted to extend through holes in the disk and into the sports apparatus.   
     
     
         9 . A device according to  claim 1 , wherein:
 the adjustment mechanism enables a predetermined longitudinal displacement of the heel support element parallel to an upper support surface of the base plate.   
     
     
         10 . A device for retaining a foot or boot on a sports apparatus, the device comprising:
 a base plate extending lengthwise from a rear end to a front end and widthwise from a first side to a second side;   a heel support element and a pivot mechanism mounting the heel support element to pivot with respect to the base plate, the pivot mechanism comprising a first pivot support and a second pivot support, said first and second pivot supports being widthwise spaced apart;   an elongated element extending from the heel support element to widthwise spaced-apart positions adjustably fixed longitudinally relative to the base plate, forward of respective ones of said first and second pivot supports, to limit rearward pivot movement of the heel support element relative to the base plate; and   an adjustment mechanism to enable a longitudinal positional adjustment of the heel support element with respect to the base plate.
