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 cross-country skiing kit with a cross-country ski binding and with a cross-country ski boot, wherein the crosscountry ski binding, for articulated connection of a cross-country ski boot to a cross-country ski, is provided with a substantially unyielding binding main body which has a stand surface for a sole of the cross-country ski boot, with a holder device which has a seat for pivotable arrangement of the cross-country ski boot about a pivot axis extending in the transverse direction of the binding main body, with an elastically deformable resetting element for resetting the cross-country ski boot from an upwardly pivoted position in the direction of the stand surface of the binding main body, wherein at least one substantially unyielding elevation is provided on the stand surface of the binding main body, to the rear of the pivot axis in the longitudinal direction of the binding main body, with which elevation the sole of the cross-country ski boot in its unloaded state is arranged at a distance from the stand surface of the binding main body.

A rear portion of a ski mountaineering binding has a base with a turret rotatable into a first position. The binding portion attaches to a ski boot heel for downhill skiing. The turret has a second position for walking uphill. A ski brake includes a braking lever rotatable to assume a braking position and a non-active position. The brake has elastic for rotating the braking lever towards the braking position, the braking lever is pressed by the ski boot heel, when the turret is in the first position, in order to reach the non-active position. A rotation member rotatably borne by the base bears the braking lever. The rotation member and the turret are interconnected and solidly constrained to one another, with the turret in the second turret position and the braking lever in the non-active position, to enable walking uphill.

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.
