A heel piece for a safety ski binding is provided comprising a support member in the form of a slide member on which is pivotally mounted a sole holder having a pedal, a sole engaging portion and an interior cam surface configured to cooperate with a bearing member or cam follower which engages the cam surface. The cam follower is supported by a bearing lever having an axis of rotation near the upper surface of the ski, and a connecting member. The cam surface has an upper portion, a lower portion and an intermediate critical portion, and the binding opens when the soleholder is driven upwardly so that the critical portion passes the cam follower. An opening lever for manually opening the binding is rotatably attached to the connecting member, and is pivotally mounted on the soleholder. A spring disposed between the axes of the opening lever and of the bearing lever biases the connecting member to urge the soleholder to a closed position when the cam follower is in the upper cam portion, and to an open position when the cam follower is in the lower cam portion.

Heelpiece for safety ski binding

The invention relates to a front piece for safety ski-bindings. The front piece comprises a supporting member which can be pivoted sideways. Linked to the support member are side clamps for engaging the toe of a ski boot in order to hold the ski boot in the front piece of the safety ski-binding. The side clamps are releasable when a predetermined force is applied to the side of the ski binding. The binding of the present invention will automatically reset after the side clamp is released and the boot is free from the binding. An advantage of the mechanism of the present invention is that internal friction is minimized during the release/reset operation. This is achieved in part by the side clamps being designed such that they are extended beyond their respective points where they are pivotally attached to the supporting member.

Heel binding

Force transducer

An electronic ski binding incorporating a capacitor for generating actuating signals to a release circuit, and a recharging circuit for recharging the capacitor from an energy source according to the energy level of the capacitor. A charge measuring circuit is provided for measuring the charge of the energy source according to the time required to recharge the capacitor.

Electronic ski binding and a method for its operation

A safety ski-binding having force transmitting surfaces which are inclined at an angle which corresponds substantially to the angle of friction. The force component acting in the direction of release of the sole plate created by the additional load compensates for the friction, so that the release resistance is not influenced even for a heavy load from the ball of the skier's foot even for the purely rotary fall load. These inclined surfaces are preferably provided on a rearward tongue which is disposed between the base plate and a rearward guide rail, the rearward tongue comprising an upper surface in substance in the shape of a flat M whose upper tips are flattened to abut in the normal position supporting elements depending from the guide rail. A forward tongue and guide rail is similarly provided and both the forward and/or rearward tongues which are configured at their lower and upper surfaces, respectively, as a W or an M, for engaging two supporting elements on a ski structure cooperating with the respective tongues for compensating for friction on the binding.

Safety ski-binding having a sole plate

An indicator in a grasping piece of a safety ski binding for indicating the setting of an adjustable operating characteristic, including a window and an elongated indicating member operatively connected at one end to the operating characteristic adjusting means, the opposite end of the indicating member bearing on the window, the indicating member being supported intermediate its ends.

Indicator for safety ski binding

A pedal-actuated ski brake which is biased into the braking position. The ski brake may be easily released from the biasing device so as to permit the ski brake to be released into a non-braking position permitting free access to the sides and bottom of the ski.

Ski brake

A pedal-actuated ski brake biased into the braking position and having a means for holding the brake prong inboard of the ski when in the skiing position. The ski brake may also have a means for biasing the brake prong outboard of the ski when in the braking position. When the ski brake is used with a turntable ski binding, the pedal is received inside an opening in the turntable and there is also a means for engaging the heel retainer so as to hinder unwanted movement.

Current supply circuit for electronic safety ski bindings

A magnetic release system of a safety ski binding having a permanent magnet, a release mechanism, a core disposed between the magnet and release mechanism in which a temporary magnetic field may be induced, an electromagnet coil associated with the core for cancelling or diminishing the magnetic field induced in the core by the magnet, and a spring biasing the release mechanism from a non-actuating to an actuating position.

Cross country ski binding

A manually releasable heel holder of a safety ski binding having a housing, a sole holder, a connecting arm movably connected to the housing and to the sole holder, and a manually actuable releasing member for releasing the connecting arm from a locking to an unlocking position, allowing the sole holder to open under the influence of a spring.

Heel holder for safety ski bindings

A method and apparatus for actuating a safety ski binding, for the purpose, in hazardous situations, of automatically releasing a ski boot from a ski on which it is held. The forces exerted by the ski on the leg of the skier are continuously integrated with respect to time. The thus formed time integral of the force releases the connection between the ski and boot on reaching a threshold value representing a product of force.times. time which is higher than the integration threshold value corresponding to the holding force of the ski binding. To avoid a summation of pulses, a pulse that has not resulted in actuation is cleared through downward integration.
