Abstract: A flat board as a base plate of a binding for splitboards with holders for the bindings' fixation on skis that are joined together to form a snowboard that has a circular slit (or opening) formed in a central part of the board. The circular slit is equipped with a perimeter recess for removable fixation of a contact ring which is, on its inner perimeter, equipped with two pairs of opposed dents (or indentations) that are designed for connection with a holder. The contact ring is also modified between the dents (or indentations) for insertion of end pins of a locking eccentric. The locking eccentric is formed by an axial shaft with end pins protruding from end hubs formed at both ends of the axial shaft.

Abstract: Systems and methods for fixing a binding board to skis that are removably connected together to form of a splitboard are described herein. In some cases, the described systems use a sliding and removable setting of bearing pins in eyes that are formed on adjacent areas of the board and a clamp that is fixed to the skis. The essence of the invention is a fixation of lateral parts of the eyes by stoppers which partially overreach into cross sections of the eyes. A diameter of the bearing pins basically corresponds with a diameter of the eyes. The bearing pins are equipped with circular recesses for engaging with the stoppers and also with end parts that each have a truncated conical tip.

The circular slit is equipped with a perimeter recessing for demountable fixing of a contact ring which is on its inner perimeter equipped with two couples of opposed dents designed for connection with a holder. The contact ring is also modified between the dents for insertion of end pins of locking eccentric. The locking eccentric is formed by an axial shaft with end pins protruding from end hubs formed at the both ends of the axial shaft.
