Abstract: A release ski binding has a sole plate which is pivotal in its central region about an approximately vertical axis and is tiltable up about a transverse axis which is arranged in front of the vertical axis, which sole plate is held in the skiing position by a resilient holding mechanism which, during a release, effects an opening of the jaws which hold the ski show on the ski.In order to bring about a simple structural design of the binding, the holding mechanism has associated with it a spring housing which is movably supported on the sole plate, the spring of which spring housing urges a locking member for the jaws into the clamping position. The locking member is arranged on the sole plate.

Abstract: A safety ski binding includes a bearing block having an axle thereon, a sole holder pivotally supported on the axle, and a spring housing supported on the bearing block for pivotal movement about an axis which is generally parallel to the axle. A slide member is movably supported in the spring housing and is biased by a release spring into engagement with a control surface on the sole holder in the downhill skiing position of the binding. The axle is closer to the tail of the ski than the axis, and the control surface on the sole holder includes a cam which engages the slide member in the region between the axle and axis. The slide member has a control recess therein and the axle extends through the control recess, pivotal movement of the spring housing causing the axle to engage an inclined surface of the slide member and move the slide member away from the sole holder against the urging of the release spring.

Abstract: A safety ski binding which can releasably hold a ski boot on a ski includes a release mechanism having a slide member which operatively engages the ski boot when it is held in the binding and moves from an initial position in a first direction in response to movement of the ski boot during a release thereof. A coupling mechanically couples the resilient arrangement to the slide member, the resilient arrangement biasing the slide member in a second direction opposite the first direction. The coupling automatically interrupts the coupling of the resilient arrangement and the slide member when the slide member has moved a first distance from its initial position in the first direction. A pickup responsive to movement of the slide member sends signals to a circuit which, when the slide member has moved a second distance less than the first predetermined distance from its initial position, actuates an arrangement which causes the coupling to interrupt the coupling of the slide member and resilient engagement.

Abstract: A safety ski binding includes a releasable jaw having a pivotally supported holding mechanism which is adapted to engage a ski shoe. 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.

Two braking arms are rotationally supported on the second pedal part, are rotationally biased by torsion springs, and have extensions engageable with surfaces on the holding plate to effect rotation of the braking arms in response to movement of the second pedal part.
