A toe-piece for binding a boot to a gliding board, the toe-piece including a frame; two wings each pivotable in relation to the frame about an axis of rotation and supporting a lateral interface surface designed to come into contact with a front portion of the boot when the toe-piece is in a descent configuration. The toe-piece further includes a lateral release mechanism that includes a connecting element connected to the wings such that the displacement of the connecting element causes the rotation of the wings about their axes of rotation; a first elastic member, a first end of which is connected to the connecting member; and a body against which a second end of the first elastic member presses. The toe-piece further includes an adjustment mechanism that acts on the wings in order to position them alternately in a first configuration, in which each lateral interface surface is in contact with the boot, or in a second configuration, in which each lateral interface surface is away from the boot, for the same positioning of the boot in relation to the toe-piece. The body of the lateral release mechanism is movable in relation to the frame.

Fixation of a binding board to skis demountable connected into a form of a splitboard uses a sliding demountable setting of bearing pins in eyes formed on adjacent areas of the board and a clamp fixed to the skis. The essence of the invention is a fixation of the lateral parts of the eyes by stoppers which partially overreach into the cross sections of the eyes. The diameter of the bearing pins basically corresponds with the diameters of the eyes. The bearing pins are equipped with circular recesses for engaging of the stoppers and also with end parts formed as from above one-sidedly reduced conical tips.

A front insert for a ski mountaineering boot has first and second heads, positionable on lateral portions of a front part of the boot, a first housing in the first head, a second housing in the second head, and two contact elements with respective holes for coupling with respective hooking elements of a binding. The housings and respective ones of the contact elements are reciprocally conformed so as to enable the contact elements to displace from internal positions with respect to the housings, towards the outside, so that the contact elements orient with respect to the housings so that the holes can misalign from an alignment axis to maintain the contact with the hooking elements following a rotation of the ski boot with respect to the ski.

A heel unit for a touring binding includes a base for mounting on a sliding board and coupling means to engage a heel portion of a sliding board boot in a downhill position of the touring binding to retain the sliding board boot on the touring binding. A release mechanism holds the coupling means so as to be moveable relative to the base and releasable from the sliding board boot, in the downhill position, in an event of action of a force exceeding a predetermined release force. An adjustment mechanism adjusts the touring binding between the downhill position and a walking position in which the coupling means are remote from and do not engage the sliding board boot. The adjustment mechanism comprises an actuation assembly manually actuatable to lock or unlock the adjustment mechanism substantially without an actuation force or with an actuation force less than the predetermined release force.

A heel unit for a downhill or a combined downhill and alpine touring ski binding has a vertical-release functional group with a tensioning device with a first spring assembly for holding a ski boot downhill, and a horizontal-release functional group with a base plate to be positioned on the ski and a slide that deflects laterally opposing the ski longitudinal direction against the force of a second spring assembly, on which the vertical-release functional group is arranged, as well as with a compression spring assembly acting on the horizontal-release functional group. The vertical-release functional group rotates on the horizontal-release functional group around an axis running vertically towards the top of the ski or towards the vertical, such that, after a limited lateral deflection of the slide, the vertical-release functional group rotates against the force of the second spring assembly to release of the ski boot into the respective lateral-release direction.

The invention relates to an automatic front unit for a ski binding, in particular a touring ski binding, wherein the automatic front unit comprises a first retaining means and a second retaining means for retaining a ski boot in the toe region of the ski boot. This automatic front unit has a first retaining configuration, in which the two retaining means are in a retaining position, in which the two retaining means are at a first distance from one another, wherein the two retaining means can cooperate with the ski boot in the retaining position such that the ski boot is retained at the automatic front unit so as to be pivotable about an axis oriented horizontally in a transverse direction of the ski. Furthermore, the automatic front unit has a step-in configuration, in which the two retaining means are in a step-in position, in which the two retaining means are at a second distance from one another, wherein the second distance is greater than the first distance and wherein the ski boot is released from the two retaining means in the step-in position of the two retaining means, wherein the automatic front unit is adjustable from the step-in configuration into the first retaining configuration and back again. The two retaining means, in order to be adjusted from their step-in position into their retaining position and back again, are mounted so as to be movable in translation relative to one another along an adjustment path, wherein a region of the adjustment path that adjoins the retaining position of the two retaining means is oriented substantially horizontally.

An apparatus for charge-assisted release of a ski binding includes an explosive material, a battery, an electrical circuit, and a processor. The explosive material is mounted on or in a ski, a ski boot, and/or a ski binding. The apparatus also includes The electrical circuit extends from the explosive material to the battery, the electrical circuit including a switch having a connected state in which the battery and the explosive material are electrically connected through the switch and a disconnected state in which the battery and the explosive material are electrically disconnected. The processor is electrically coupled to the switch and configured to generate an output signal that transitions the switch from the disconnected state to the connected state in response to an input signal from one or more sensors.

A toe-piece of a ski binding includes rotatable first and second clamping members respectively provided with first and second jaws. First and second rotatable supports rotatably bear the first clamping member and the second clamping member, respectively. In a ski descent configuration, the first and second jaws can elastically retract if solicited by a tip of a ski boot. The first clamping member has a third jaw with a first pin, while the second clamping member has a fourth jaw with a second pin. Locking means are provided which when the ski boot tip is between the third and fourth jaws, the blocking means are activatable to block the third and fourth jaws in angular blocking positions in which the first pin is inserted in a first hole of a ski boot and the second pin is inserted in a second hole of the ski boot, making walking uphill possible.

A brake arrangement for a touring binding, adjustable between a braking position and a sliding position. The brake arrangement includes a base having a fastening arrangement for fastening to one or more of a ski or the touring binding, a pedal having a step surface for a shoe on a side of the pedal facing away from the ski, at least one brake arm mounted on the base and on the pedal, at least one first resilient element configured to preload the brake arrangement into the braking position, and a locking element that is movable between an engaged position and a disengaged position. The locking element, in the engaged position, is designed to lock the brake arrangement in the sliding position. The locking element may be preloaded into the engaged position. The brake arrangement may include a blocking element that is adjustable between a blocking position and a release position.
