A brake arrangement for a touring binding adjustable between a braking position and a sliding position, including: a base having a fastening arrangement; a pedal; at least one brake arm mounted on the base and on the pedal; at least one first resilient element to preload the brake arrangement into the braking position; a locking element that is linearly displaceable along a longitudinal direction of the ski to adjust between an active position, which locks the brake arrangement in the sliding position, and a passive position; and an actuating element mounted on the brake arrangement pivotable about a pivot access, the actuating element adjustable between a locking position, where the locking element is set into the locking position, and a release position, where the locking element is set into the passive position, and wherein a pivoting movement of the actuating element causes a linear movement of the locking element.

A toe-piece of a ski binding for ski mountaineering has a base, a first jaw, a second jaw, an activating lever, a joint, a housing, and elastic means. The first jaw is provided with a first guide, and the second jaw is provided with a second guide. The activating lever is rotatably coupled to the base. The joint is activatable by the activating lever, which includes a first sliding element slidably coupled with the first guide and a second sliding element slidably coupled with the second guide, so that the activation of the activating lever causes, via the joint, the rotation of the first jaw and the second jaw. The housing is borne by the base. The elastic means are arranged in the housing so as to push the joint to wedge against the first jaw and the second jaw.

A front unit for a touring binding, comprising: two lateral bearing portions arranged on a ski transverse axis, wherein, when the front unit is in a closed position, the two lateral bearing portions are configured to engage lateral counter bearing portions of a ski boot to hold the ski boot on the front unit so that the ski boot can pivot about the ski transverse axis; and a longitudinal positioning portion on which the ski boot can be supported, wherein the counter bearing portions are positioned for engagement relative to the bearing portions, the front unit being shiftable between an open position and the closed position, wherein the bearing portions and the counter bearing portions are disengaged in the open position and engaged in the closed position, wherein the longitudinal positioning portion, relative to the bearing portions, is secured in the open position and movable in the closed position.

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.

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.

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.

A toe-piece of a ski binding for ski mountaineering has a base, a first jaw, a second jaw, an activating lever, a joint, a housing, and elastic means. The first jaw is provided with a first guide, and the second jaw is provided with a second guide. The activating lever is rotatably coupled to the base. The joint is activatable by the activating lever, which includes a first sliding element slidably coupled with the first guide and a second sliding element slidably coupled with the second guide, so that the activation of the activating lever causes, via the joint, the rotation of the first jaw and the second jaw. The housing is borne by the base. The elastic means are arranged in the housing so as to push the joint to wedge against the first jaw and the second jaw.

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.
