The jaw includes first and second cylinders with fluid actuated pistons therein, and a fluid channel interconnects the cylinders. A check valve in the fluid channel resists fluid flow from the first cylinder to the second, and a solenoid controlled valve in the fluid channel, when open, creates a bypass around the check valve. A mechanism is provided for applying forces to the piston of the second cylinder to pressurize the first cylinder via the check valve causing the piston of the first cylinder to itself be urged against or to urge another member against a locking track in a manner which maintains the jaw in a closed position. In a preferred embodiment, the cylinders are provided on the holding mechanism and the locking track is fixed to the ski. Sensors responsive to forces exerted on the holding mechanism by the ski shoe drive a control unit which, when the forces exceed a predetermined threshold, actuates the solenoid controlled valve to release the jaw.Other References
