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.

The invention relates to an automatic heel unit for a ski binding, in particular a ski-touring binding, comprising a heel retainer, for retaining a ski boot in a heel area of the ski boot, and a heel retainer support on which the heel retainer is mounted so as to be movable along an adjustment path relative to the heel retainer support. The automatic heel unit has a holding configuration in which the heel retainer is located in a holding setting and the heel retainer can interact with the heel area of the ski boot held in the ski binding in such a way that the heel area of the ski boot is held in a lowered position. Furthermore, the automatic heel unit has a walking configuration in which the heel retainer is located in a walking setting and the heel area of the ski boot held in the ski binding is freed from the heel retainer and can be lowered toward the ski without being locked by the heel retainer in the lowered position. The heel retainer in its walking setting is located farther to the rear than in its holding setting and is movable from its walking setting to its holding setting and back again along a first area of the adjustment path. Starting from its walking setting, the heel retainer is movable along the first area of the adjustment path, beyond its holding setting, upward from the first area of the adjustment path into a second area of the adjustment path separate from the first area of the adjustment path and adjoining the first area of the adjustment path, and back again.

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.

Disclosed herein are systems and methods relating to a snowboard that includes a raised edge rail and one or more pockets where the sidecut meets the nose and/or tail of the snowboard; and to a snowboard that includes a braking system. Aspects of the present disclosure relate to a snowboard that includes one or more sensors, including position sensors, distance sensors, accelerometers, or other sensors, that may detect information related to the snowboard motion and/or position. Sensor data may be utilized, in some aspects, to signal a braking system to engage under certain conditions.

An apparatus for supporting a board is disclosed. The apparatus includes a support device including a support bar extending beyond the board toward the ground when deployed to provide support to the board.

A ski brake having two brake pins which can be moved from a non-fixed position to a fixed position in which the brake pins are held in a position to the side of the ski, including a brake housing, a pedal, a lever-like brake support which has a knob-like projection, and having a locking lever rotatably mounted on the brake housing and which can be moved into a lowered and a raised position. The locking lever is arranged on a locking bolt which is rotatably mounted on the brake housing and which can be rotated to a limited extent relative to the locking lever, on which at least one torsion spring. To establish the fixed position of the brake pins, the locking lever can be raised and in a second phase the locking bolt holds the brake support via the knob-like projection.
