Snowboard binding

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 an attachment location on 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 plate 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

at least one intermediate element, each intermediate element:

mounted below the heel support element;

mounted above a side plate that is connected to one side of the base plate;

having, on a lower side, an interacting section that engages with a counter section on the side plate; and

adjustable in its location relative to the rear and front ends of the base plate;

wherein the attachment location, first pivot support, and first lower connection collectively define a generally triangular shape when viewed from a side of the device when the heel support element is in a closed position around a user's heel.

2. The device according to claim 1 , wherein:

the at least one intermediate element enables a predeterminate longitudinal displacement of the heel support element independent of the elongated element.

3. The 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. The device according to claim 1 , wherein:

the device is a snowboard binding for retaining a snowboard boot on a snowboard.

5. The device according to claim 1 , further comprising:

an assembly to mount the base plate to the sports apparatus.

6. The device according to claim 5 , 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.

7. The device according to claim 1 , wherein:

the at least one intermediate element enables a predetermined longitudinal displacement of the heel support element parallel to an upper support surface of the base plate.

8. 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

at least one intermediate element, each intermediate element:

mounted below the heel support element;

mounted above a side plate that is connected to one side of the base plate; and

adjustable in its location relative to the rear and front ends of the base plate.

9. The device according to claim 1 , wherein the interacting section on each intermediate element and the counter section on the side plate are toothed sections.
