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.

An apparatus for holding a footwear heel to a snow travel aid is provided. The apparatus comprises a mountable base connected to a generally vertical post and an upper portion having at least one forward connector for connecting the upper portion to the heel. The upper portion is rotatable on the post between a downhill position and at least one touring position and comprises at least one part which travels over a prominence at a fixed location relative to the upper portion during rotation from the downhill position to the touring position. The at least one part becomes engageable with a depression adjacent the prominence when the upper portion is in the touring position to resist rotation from the touring position back to the downhill position. The post comprises a feature that provides clearance for the at least one part to travel over the prominence or which functions as the prominence and depression. Also provided are posts for use as a part in such an apparatus.

A system for optional dynamic positioning of a ski binding or parts thereof on or in a ski during use, the system comprising a motor, an energy source for driving the motor, a control system arranged to control the motor and a track that transmits power from the motor to the ski binding or parts thereof.

A pin binding toe unit for holding a footwear toe to a snow travel aid has a pair of pivotal jaws with respective teeth for engaging concavities in sides of the footwear toe, and a biasing element operable to bias the jaws into open and closed positions. In contrast to conventional incorporation of multiple biasing elements into the jaws, the biasing element is instead uniquely housed in the mode lever by which the jaws are openable and closeable, and in this housed relation to the mode lever, the biasing element is constrained to a uniform horizontal orientation through the full range of jaw motion. The assembly is simplified, torque leverage on the jaws is advantageously varied within the range of the jaw motion for improved energy absorption, and the trigger of the mode lever is uniquely widened for easier user step-in. Threaded pivots enable disassembly of components for service and end-of-life recycling, with the two threaded jaw pivots being characterized by opposing thread directionality or opposing insertion orientation for self-prevented loosening of the threaded jaw pivots over repeated open-close cycles.

The toe-piece of a ski mountaineering binding comprises: a first jaw and a second jaw rotatably coupled with a base fixable to a ski; a first hooking element borne by the first jaw and having a first tip for inserting in a first lateral hole of a ski boot and a second hooking element borne by the second jaw and having a second tip for inserting in a second lateral hole of the ski boot when the toe-piece assumes a configuration of an inserted ski boot. The toe-piece is configured so that the first hooking element is inserted in a first seat in the first jaw to enable a roto-translatory motion between a retracted position when the boot is aligned to the longitudinal axis of the ski, and a plurality of possible advanced positions when the ski boot temporarily misaligns with respect to the longitudinal axis of the ski.

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.

A boot binding system for a splitboard that can include a latch pedal mechanism at an end of a baseplate on which the rider's boot rests. The latch pedal can have a dual function: either to attach each boot binding to a ride mode interface, or to attach each boot binding to a ski tour interface. In a release position the latch pedal is disengaged allowing the baseplate assembly to alternate between the ski tour interface and the ride mode interface. In a lock position, the rider depresses the latch pedal and locks the boot binding onto the selected interface. The latch pedal is held down by the rider's boot when in the lock position, contributing to the system's lightness and strength.

A binding for a touring ski, a Telemark ski or a cross-country ski having step in automatic locking. The binding includes a front retaining element to cooperate with the front sole of a boot, a rear retaining element to cooperate with the rear part of the front sole and/or the rear sole of the boot, a tensioning element to tension the boot on the binding and to enable the heel to be freely lifted, a tensioning link placed under and connected to a rear retaining stirrup, and a fixed or retraction stop to cooperate with the tensioning link so as to enable the rear retaining stirrup to move back, tensioning the tensioning element, when the heel of the boot exerts a downwardly directed pressure on the rear retaining boot situated in an idle position.

boot on a sliding board, having a base (130; 3) intended to be fixed to the sliding board,

two lateral jaws (101; 8, 9), each mounted to be rotationally mobile on the base (130; 3) about a substantially vertical rotation axis (103; 10, 11), so as to occupy a closed position to hold a boot and a separated position to release or receive a boot,

and a pusher (110; 35) having two lateral trig surfaces (114; 24, 25) each cooperating with a respective ramp (104; 22, 23) of each jaw (101; 8, 9), this pusher (110; 35) being linked to the base (130; 3) by a trig spring (112; 36)

and two links (120; 28, 29) each linked to a jaw (101) by a first lateral axis (123; 14, 15) and linked together by at least one central axis (125; 32).

The invention relates to a heel-piece for binding a boot on a gliding board that includes a frame including a vertical extension; a body rotatably mounted about the extension; at least two rods supported by the body, extending on respective sides of the vertical extension, the two rods each having a free end to cooperate with a housing in the heel of the boot; and a holding mechanism for maintaining a spacing between the free ends of the rods. The vertical extension supports at least one contact zone fixed in relation to the frame. Each rod cooperates with a respective portion of the contact zone, specific to each rod. The contact zone is arranged such that a rotation of the body about the extension, from a descent configuration, causes an increased spacing between the two rods. The invention also relates to a binding system and a gliding board equipped with such a binding.
