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 mm2 mm in at least one point.

A binding system for a touring ski binding has a front jaw device and a rear jaw device for receiving a ski boot. In a descent mode, the front jaw device is open and the rear jaw device is closed, so that a retainer can receive a web of the ski boot, and a lever mechanism can fix a heel part of the ski boot. The rear jaw device with the lever mechanism exerts a contact pressure on the heel part of the ski boot along a boot longitudinal axis (X), so that the web is pressed into a hook system of the front jaw device, and the ski boot is thus secured against translation against the boot longitudinal axis (X).

A skiing equipment (1) is provided, comprising two skis (3) each including a base body (31), a fastening group (32) for attaching (3d, 3e) to the base body (31); a track (4) closed around the base body (31); a mover (5) for the said track (4) around the base body (31); sensors configured to detect a movement of said ski (3) relative to said terrain (1a); and a control unit (6) for said mover (5) of each of said skis (3) and thus the sliding of said track (4) around said base body (31) based on said movement of said ski (3) relative to said terrain (1a).

Skiing equipment (1) is provided comprising a ski (2); a track (3) closed on itself and wound around the ski (2); a mover of the track (3) around the ski (2); a fastening group (4) for at least one binding (4a, 4b) defining together with the ski (2) a channel (4c) for the sliding of the track (3); and wherein the track (3) comprises a belt (31) wound longitudinally around the ski (2) and defining two ends (31a, 31b); and a hinge (32) constraining the ends (31a, 31b).

The invention relates to an automatic heel unit (1) for a ski binding, comprising a base (7) for fitting the automatic heel unit (1) on a ski and a heel downholder (3) for holding down a ski boot in a heel region of the ski boot. The heel downholder (3) is mounted so as to be movable in relation to the base (7). The automatic heel unit (1) has a holding configuration in which the heel downholder (3) is located in a holding position and may interact with the heel region of the ski boot that is held in the ski binding in such a manner that the heel region of the ski boot is held down in a lowered position. Furthermore, the automatic heel unit (1) has a step-in configuration in which the heel downholder (3) is located in a step-in position and the heel region of the ski boot is released by the heel downholder (3). The automatic heel unit (1) comprises a heel support structure (6), which is configured separately from the heel downholder (3), for supporting, in a direction that is horizontally transverse to the ski, the heel region of the ski boot that is held in the ski binding in the holding configuration of the automatic heel unit (1).

Traction systems for skis producing traction on snow and ice covered surfaces; the skis selected from a group consisting a pair of Back Country skis each are mounted with an apparatus; having DC powered controls, tilt switch, pressurized carbon dioxide (CO.sub.2) gas powered pneumatic actuators operating gripping parts; controlled by a servo unit. And further consisting a pair of snowmobile skis each having an assembly of parts; driven by an hydraulic rotor that pivots the skis, adjusting their position when cornering, providing traction, according to a snowmobile steering system. And is powered and controlled by at least one of: hydraulic steering system, an electro-hydraulic steering system; an electric power steering system using an electric motor instead of hydraulic rotor.

An apparatus is provided for holding a footwear toe to a snow travel aid. The apparatus comprises jaws that grasp the toe while permitting pivotal movement of the footwear about the toe in forward and rearward directions and is for use with a heel holder that provides for lateral release. The apparatus comprises one or more resilient elements for biasing the jaws whereby the jaws are biased towards a closed position throughout the operational range of motion of the jaws. Also provided is an apparatus which comprises jaws that grasp the toe while permitting pivotal movement of footwear about the toe, wherein the apparatus is adapted for generally horizontal, forward and rearward translation relative to a longitudinal axis of the snow travel aid, selectively by a user. Also provided is an apparatus comprising jaws that grasp the toe while permitting pivotal movement of footwear about the toe, and a lock for inhibiting opening of the jaws, the lock comprising one or more resilient elements which provide resilience while inhibiting opening of the jaws.

Braking device for a gliding board that includes: a base to be affixed to the gliding board; at least one braking arm pivotable about a first substantially transverse axis, the braking arm including a control element extending along an axis substantially parallel to the first axis; a movable support plate including a control element housing, the position of the control element in the guiding housing varying as a function of the angular position of the braking arm; an elastic mechanism acting on the control element along an actuation direction varying as a function of the angular position of the braking arm. The support plate is displaced by an amplitude covering a first positioning range for which the base, the braking arm, the support plate, and the elastic mechanism are arranged so that the elastic mechanism acts on the control element to cause rotation of the braking arm in a first direction, as well as a second positioning range for which the base, the braking arm, the support plate, and the elastic mechanism are arranged so that the elastic mechanism acts on the control element to cause rotation of the braking arm in a second direction, opposite the first direction of rotation.

A heel unit including a base comprising a fastening arrangement for fastening to a gliding board, a binding body, and coupling means arranged on the binding body. The coupling means engage with a heel portion of a gliding board boot in a downhill position of the gliding board binding to securely hold the gliding board boot on the gliding board binding. The coupling means protrude in a longitudinal direction from the binding body in the downhill position. The heel unit includes an Mz release mechanism to preload the coupling means into the downhill position so that, in the downhill position, the coupling means are freed from engagement with the gliding board boot upon action of a force exceeding a predetermined release force, and so that the coupling means move from the downhill position into a release position via rotational movement of the binding body about the release axis of rotation.

A skiing equipment (1) is provided, comprising a ski (2) defining a longitudinal direction (2a) and two ends (2b, 2c) and including at least an upper layer (21), a lower layer (22) mutually coupled, and a groove (25) passing through the upper and lower layers (21, 22) between the ends (2b, 2c) and delimited by at least two transverse edges (25a) extending transversely to the longitudinal direction (2a) and two lateral edges (25b) extending parallel to the longitudinal direction (2a); wherein each of the lateral edges (25b) includes a first insert (26) extending parallel to the longitudinal direction (2a) and including a material that is more rigid than the rest of the lateral edge (25b).
