A ski binding attachment (3) comprising:—an attachment plate (60) designed to be mounted on a ski,—an exchangeable fastening element (30) designed to be detachably mounted on a forward part of the attachment plate (60), where the attachment plate (60) and the fastening element (30) comprise respectively one or more first locking elements (301a, 302a) and one or more second locking elements (311a, 312a), the first locking elements (301a, 302a) and the second locking elements (311a, 312a) engaging with one another and locking the fastening element (30) in the longitudinal and lateral direction of the attachment plate (60) when the fastening element (30) is arranged from above and down onto the attachment plate (60).

An apparatus for charge-assisted release of a ski binding includes an explosive material, a battery, an electrical circuit, and a processor. The explosive material is mounted on or in a ski, a ski boot, and/or a ski binding. The apparatus also includes The electrical circuit extends from the explosive material to the battery, the electrical circuit including a switch having a connected state in which the battery and the explosive material are electrically connected through the switch and a disconnected state in which the battery and the explosive material are electrically disconnected. The processor is electrically coupled to the switch and configured to generate an output signal that transitions the switch from the disconnected state to the connected state in response to an input signal from one or more sensors.

A ski binding moving mechanism (1) comprising:a ski binding (2a) configured to be fastened in the vertical and lateral direction on a ski, and further configured to be movable in the longitudinal direction relative to the ski;a rod (5) with two or more pushing elements (51a, 51b, . . . ), the rod (5) being fastened to the ski binding (2a); anda rotatable element (32), configured to be fastened fixedly relative to the ski in the longitudinal direction of the ski, the rotatable element (32) being rotatable relative to the ski (6), wherein the rotatable element (32) comprises:a first and a second rotating pin (321, 322) configured to rotate with the rotatable element (32), and cooperate with the pushing elements (51a, 51b, . . . ), whereinthe rotatable element (32) is configured to be rotated at least one revolution and move the rod (5) and the binding (2a) in the same longitudinal direction throughout the revolution.

Coupling assembly between a footwear and a sport equipment comprising at least one housing on the footwear near the sole suitable for receiving a first metallic element, a binding, on the sport equipment, provided with a seat for the insertion of the footwear, the binding being equipped with at least a second metallic element positioned in the seat, the first or the second metal element being an electromagnet, which when activated is magnetically bound to the other element.

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.
