A mounting plate and mounting plate system for a ski comprising: a bottom surface configured to be placed against a ski; an upward directed left and right side edge along the outer sides of the mounting plate, where the edges have laterally opposed undercuts that are configured to hold a ski binding with complementary cuts fastened to the mounting plate in the vertical direction; a longitudinal groove, configured to hold a first interchangeable rail fixed in the lateral direction and the longitudinal direction, and a second interchangeable rail which can be interchanged with the first rail, fixed in a lateral direction but movable in the longitudinal direction.

The present invention relates to a mounting system for a binding, or a binding component (2; 4) on a cross-country ski, where a mounting plate (6) is arranged on the top surface of the ski and where the mounting plate (6) comprises longitudinal side edges having a profile (33) with undercuts for longitudinal positioning and attachment of the binding or binding component (2; 4) with the aid of a complementary profile (34) on the binding or binding component (2; 4). According to the invention, the mounting plate (6) comprises a longitudinal channel (21) that houses a longitudinal rail (5), where the upper side of the rail (5) comprises at least one locking device (20; 23), and where the underside of the binding or binding component (2; 4) comprises at least one complementary locking device.

The present invention relates to a front unit (10) for a touring binding, which front unit is to be mounted on a sliding board and has a mounting surface pointing in the direction of a sliding board surface, which mounting surface defines a sliding board plane (E), the front unit (10) being adjustable between a downhill configuration and a climbing configuration, comprising a first holding device (20) which is designed to fix a front portion of a sliding board boot for downhill travel with the touring binding, in the downhill configuration of the front unit (10), the first holding device (20) being adjustable between an active position and a passive position, and the first holding device (20) being set into the active position in the downhill configuration of the front unit (10), and being set into the passive position in the climbing configuration of the front unit (10), and a second holding device (40), which is designed to secure a toe portion of the sliding board boot for ascent with the touring binding in the climbing configuration of the front unit (10), in such a way that the sliding board boot is pivotable about a hinge pin that is substantially in parallel with the sliding board plane (E) and substantially perpendicular to a longitudinal axis (L) of the sliding board, the first holding device (20) being arranged closer to the sliding board plane (E) in the passive position than in the active position. Furthermore, the present invention relates to a touring binding comprising the front unit (10), which touring binding further comprises a heel unit and optionally a brake assembly.

The present invention concerns a system for optional dynamic positioning of a ski binding (2) or parts of this, on or in a ski during use. The invention is characterized in that the system comprises an electrical actuator (6), an energy source (7) in order to run the electrical actuator, in addition to a control system (8) adapted to control the electrical actuator.

System for a touring ski-binding comprising a front unit and heel unit comprising a heel member, wherein the stopper plate is switchable between an adjacent position and a protruding position, wherein the stopper plate is configures to leave the adjacent position when the touring ski binding is released, wherein the heel unit is switchable between a starting position for providing a blocking function and for receiving a ski boot, and a snap-in position for retaining the ski boot, wherein the heel unit comprises a walking means by means of which the stopper plate can be blocked in the adjacent position, wherein the blocking means with respect to the pivot axis is switchable between a blocking position and a non-blocking position depending on the position of the heel member, wherein with respect to the downhill mode the front unit in the climbing mode of the touring ski-binding is displaced to the front in the longitudinal direction of the ski, so that a ski boot present in the touring ski-binding cannot contact the heel member of the heel unit.

A heel unit for a touring ski-binding, comprising, a heel member, wherein the heel member comprises a reception bowl for receiving the heel part of a ski boot and a biasing device for biasing the heel unit against a ski boot, and wherein the heel unit is switchable between a starting position for receiving or releasing the ski boot and a snap-in position for holding the ski boot, wherein the heel unit comprises a blocking means by means of which the heel unit can be blocked in the starting position, wherein the blocking means is switchable between a blocking position and a non-blocking position.
