Mechanism for adjusting the orientation of bindings on a snowboard

A device for setting an orientation of a binding of a boot on a snowboard, comprising:

• a disk configured to be fixed to the snowboard, the binding being mounted movable in rotation relative to said disk, around a vertical axis of rotation;
• a ring is mounted movable in rotation in relation to the disk around the vertical axis of rotation;
• at least one locking element mounted adjustably between:
• a locked position where the binding is immobilized in relation to the disk, and
• an unlocked position where the rotation of the binding around the vertical axis of rotation for an angular adjustment of said binding in relation to the board is allowed;
• and
• a shift of the locking element between the locked position and the unlocked position is ensured by an actuator,
• wherein the actuator is remotely controllable, the locking element and the actuator are installed in the disk so that said actuator can be actuated when the boot is retained in the binding, and said locking element is movable by said actuator when the boot is retained in said binding, and the locking element is in the form of retractable teeth installed in the disk and which, in the locked position, cooperate with complementary teeth arranged on the ring.
