A rear portion of a ski mountaineering binding includes a base, a turret rotatable with respect to the base, a brake fixable to the ski for braking the ski, first elastic element arranged to exert a force to bring the brake into a braking configuration, and a hooking member borne by the base and having a hook for hooking the brake. The hooking member has engaged and disengaged configurations. A second elastic element pushes the hooking member into the engaged configuration. A cam borne by the turret has a pusher borne by the base, activatable by the cam and movable along a second movement path. The hooking member includes an abutment for abutting the pusher and is activatable by the turret via the cam and the pusher, to assume the disengaged configuration and alternately the engaged configuration.

A thrust-responsive structure for skis includes a plurality of retractable elements. Each retractable element includes a portion configured to move from an elevated position to a retracted position. Each retractable element further includes a first retention feature. The structure further comprises a matrix surrounding at least a subset of the plurality of retractable elements. The matrix is static relative to the plurality of retractable elements. The matrix includes a plurality of second retention features configured to captively engage the first retention features of the plurality of retractable elements. A position of each retractable element of the plurality of retractable elements, in the elevated position, is limited by contact between the first retention feature and the second retention feature.

The present invention relates to a braking system for a recreational riding-board. The braking system includes a braking mechanism and an activating means. The braking mechanism is adapted to slow down or stop, the motion of the riding-board. The activating means is adapted to control the braking mechanism. The activating means in use is located between the middle and rear end of the riding-board.

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 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.
