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.

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 touring skibinding (1) comprises a support element (2) which can be fastened to the ski, a bearing element (3) with a skiboot reception (4) which is designed in such a way that the skiboot (5) can be mounted in the skiboot reception (4) such that the skiboot can pivot about a first pivot axis (S1) with respect to the skiboot reception (4) and a convex supporting surface (6) on which the skiboot (5) can roll, the bearing element (3) being connected to the support element (2) so as to be pivotable about a second pivot axis (S2) from an initial state into a pivoted state, wherein the skiboot (5) is moveable from a standing state, in which the skiboot (5) stands on the convex supporting surface (6), into a pulling state, in which the skiboot (5) is at least partially lifted from the convex supporting surface (6), wherein, starting from the standing state, the skiboot (5) is movable on the convex supporting surface (6) in the direction of the pulling state in such a manner that the skiboot (5) rolls on the convex support surface (6), wherein a pivoting movement of the skiboot (5) about the first pivot axis (S1) and of the bearing element (3) about the second pivot axis (S2) is effected simultaneously with the rolling process.

A brake arrangement for a touring binding, adjustable between a braking position and a sliding position. The brake arrangement includes a base having a fastening arrangement for fastening to one or more of a ski or the touring binding, a pedal having a step surface for a shoe on a side of the pedal facing away from the ski, at least one brake arm mounted on the base and on the pedal, at least one first resilient element configured to preload the brake arrangement into the braking position, and a locking element that is movable between an engaged position and a disengaged position. The locking element, in the engaged position, is designed to lock the brake arrangement in the sliding position. The locking element may be preloaded into the engaged position. The brake arrangement may include a blocking element that is adjustable between a blocking position and a release position.

A brake device for a sliding board, including: a base for connecting the brake device to the sliding board; and a brake, including: at least one brake paddle; a latching element which can be moved back and forth between a first position in which the brake paddle can be released in order to slow the sliding board and a second position in which the brake paddle can be fixed in a non-braking position; and a pedal which includes a bearing area for a boot and a functional element which can be moved relative to the bearing area, wherein moving the functional element releases the latching element to be moved from the first position to the second position.
