Abstract: 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.

Abstract: This invention provides an improved ski braking mechanism wherein the braking unit comprises a pair of Z-shaped, independently movable rods each having an outer leg attached to a braking spur, an inner leg attached to a brake pedal, and a central cross-bar forming a pivot axis. A stop is provided to inhibit the movement of the braking spurs towards the longitudinal middle section of the ski when the spurs are in the lowered braking position. Each braking spur is retractable towards the longitudinal middle section of the ski when the spurs are in the raised skiing position.

Abstract: 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.

Abstract: A heel holder of a ski binding for assuming an open position from a closed position when a ski boot is released from a toe holder of the binding, the heelholder including a baseplate, a housing mounted on the baseplate, a soleholder pivotally mounted on the housing for rotation between open and closed positions, a retaining member mounted on the soleholder for releasably retaining the soleholder in the closed position, a locking member for releasably restraining the retaining member to lock the soleholder in the closed position, a blocking member for blocking the retaining member from movement from its restrained position and a release member for moving the blocking member to free the retaining member when a ski boot is released from the toe holder to enable the opening of the soleholder.

Abstract: 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.

Abstract: A method and apparatus for automatically releasing a ski boot from a ski on which the ski boot is held by a ski binding. Circuitry is provided for continuously monitoring over a time integral the forces exerted by the ski on the leg of the skier. The monitored forces are compared with a characteristic threshold value representing a product of force .times. time, which lies above an integration threshold value corresponding to the holding force of the ski binding. The connection between the ski and boot is released when the monitored forces exceed the characteristic threshold value. The characteristic threshold value is varied independently of a static actuating force by varying the integration threshold value.

Abstract: A heelholder for a safety ski binding comprising a carriage, a soleholder pivotally mounted on the carriage and carrying a lever, a first locking lever mounted on the carriage and disposed in the path of the soleholder lever and biassed towards a blocking position by a release controlling spring so that the soleholder normally cannot be opened unless the force of the spring is overcome, a second locking lever for releasably blocking the soleholder lever from movement from a position obstructed by the first locking member, and a toggle joint for voluntarily moving the second locking lever to unblock the soleholder lever to enable release of the binding with a small force.

Abstract: 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, 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 and an interim lever for automatically releasing the connecting arm from a locking to an unlocking position when a ski boot is released from the ski by the toe unit.

Abstract: A heelholder for a safety ski binding having a baseplate, a slide mounted for movement between forward and rearward positions, a soleholder pivotally mounted on the slide for movement between closed and open position, a locking device mounted on the soleholder for movement between an obstructed position where it holds the soleholder in the closed position and an unobstructed position, a locking lever for releasably obstructing the locking device against movement from the obstructed position, and a blocking lever mounted on the slide for movement between a blocking condition wherein the blocking lever holds the locking device in the obstructed position and an unblocking condition wherein the blocking lever moves the locking device out of the obstructed position.

Abstract: A locking device for an electronic safety ski binding comprises two interengaged locking members of which the locked member is connected to a sole retainer and is movable between its releasing and its retaining position in which it is held by the locking other member which is movable by an electromagnet. To provide a shockproof lock for an electronic safety ski binding with a reliably operative electromagnet, a rotary magnet is provided to move the locking member.

Abstract: To test the setting of safety ski bindings, a force testing device comprises a permanent magnet securable to a binding. The attractive force of the permanent magnet holds a soft iron plate comprising force engagement means on which the force producer of the binding can act.

Abstract: A safety ski binding comprises force-pick-ups for generating electric signals in response to forces and/or torques acting on the skier's leg, an electronic integrated circuit for initiating the operation of the releasing mechanism by a tripping signal generated in response to the occurence of dangerous forces or torques, and a rechargeable battery for feeding the circuit. In order to avoid a continuous maintenance of the battery (B) it is supplied with charging current from a generator (8, 10; 21, 22). The generator comprises parts that are movable relative to each other for a generation of electric power and are respectively connected to a member (1) of the ski binding and to the surface of the ski (5).

Abstract: In a ski stopper having a pivoted spur spring-biassed to swing to a braking position in the absence of a ski boot on a pedal connected to a spur extension, a coupling member displaceable on the spur extension by the biassing spring and the pedal is secured to the ski, or a part fixed thereto, by a connection which is only deliberately releasable.
