Ski binding adapted for emergency release. A ski binding is provided with a pair of mechanical parts which are arranged to separate during release of the binding. A permanent magnet is affixed to one of said parts and an electromagnet is affixed to the other thereof, the electromagnet being energizable either at the will of the skier or by remote control. Same is energized under normal skiing conditions and holds the binding closed with a relatively high level of force which can be overcome under emergency conditions to effect release of the binding. However, if a condition of danger is anticipated, the electromagnet can be de-energized, whereupon the holding force remaining is only that of the permanent magnet and the holding force thereupon is reduced to a lesser level. This, while not opening the bindings, makes it possible for same to open under the impact of a lesser opening force. Control of the electromagnet may be manually in response to a switch controlled by the skier or by remote control, such as impulses received from a transmitter which in turn is responsive to bio-chemical electrical impulses derived from the muscles of the skier. |
