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 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 ski binding release system includes a spring that is releasably maintained in a first state using a pyrotechnic fastener. In the first state, a ski boot is secured in the ski binding. The pyrotechnic fastener is electrically coupled to an activation circuit. The activation circuit includes a battery, a plurality of sensors, a switch, and a controller. When the controller determines that the skier has fallen, the controller generates an output signal that transitions the switch from a disconnected state to a connected state. In the disconnected state, the pyrotechnic fastener is electrically disconnected from the battery. In the connected state, the pyrotechnic fastener is electrically connected to the battery. Electrical energy from the battery causes the pyrotechnical fastener to explode to transition the spring from the first state to a second state to release the ski boot from the ski binding.

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.

Some aspects include a ski binding system using controllable electromagnets, alone or in combination with permanent magnets, as means of attaching or releasing a ski boot to a ski during use. Some aspects include a ski binding system using a controllable solenoid. In some aspects, microprocessor-based control releases binding electronically based on input from sensors located in binding, ski and/or boot, as well as in other equipment or clothing connected to them or to skier, or binding releases when a mechanical threshold is overcome. In some aspects, sensor data are recorded for analysis of system performance and for adjustment and improvement of system parameters based on data analytics.

A binding having a front plate (2), a front assembly (3) for immobilising the boot and capable of cooperating with the sole (81) of the boot (8), a rear assembly (6) for retaining the boot and capable of cooperating with a retaining lug (85) of the rear portion of the front sole and/or with the rear sole, the rear assembly being movable relative to the front plate in the vertical plane, and tensioning means (66) which act between the rear retaining assembly (6) and the ski and/or the front plate (2) and which are capable of tensioning the boot (8) on the binding (1) and enabling the heel to be raised freely. The front immobilisation assembly is mounted in a floating manner on the front plate about a transverse pivot axis (A3), the supporting point enabling the front end (81′) of the sole (81) of the boot.

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 a combination of a downhill binding or downhill ski binding, in particular a front jaw of the downhill binding, and a ski boot. The ski boot (10) comprises a rigid ski boot shell (11) and a sole (1) of the ski boot comprising a front end (1b) of the sole, a rear end of the sole, an upper side (1a) of the sole and a lower side (1c) of the sole. The downhill binding comprises a front jaw (20) and a rear jaw, wherein the downhill binding comprises a bearing structure (2) for the sole (1) of the ski boot. The bearing structure (2) has an apex (5) which has a distance (X1), in the longitudinal direction (X), from the front end (1b) of the sole held in the downhill binding of at least 28 mm and at most 34 mm, and wherein the apex (5) exhibits a perpendicular distance (Y2) from the upper side (1a) of the sole of the ski boot held in the downhill binding of 19 mm±2 mm in at least one point.
