In a sliding device for a ski boot that is to be released from a safety ski binding and that comprises a supporting plate securable to the ski and a slide plate displaceable on said supporting plate against the force of at least one spring, positive guiding means for the slide plate on the supporting plate are avoided insofar that only the spring is used to hold the plates together, there being substantially line contact between the two plates in a direction transverse of the ski.

Sliding device

A ski stick comprising a tubular shank having a handle near one end is provided with an impact surface formed by an extension of said stick extending at an acute angle to the longitudinal axis of said shank and intersecting same.

Ski stick

In a ski brake comprising a pedal for pivotally mounting on a ski and two brake prongs for projecting downwardly from the ski at opposite sides thereof, the pedal is formed from spring wire shaped to define two coplanar open loops. The adjacent ends of the loops are interconnected to form a junction which is spaced from the pivotal axis of the pedal. The junction is linked to a coupling member which extends beyond the pivotal axis and is there hinged at a point that is fixed with respect to the ski.

Ski brake

In a safety ski-binding where the ski boot is connected to the ski by a sole plate which is releasably held to the ski by retaining means, any undesirable play between said retaining means and the sole plate that might be caused by manufacturing tolerances, inaccuracies in assembly and the like is compensated by the provision in a recess of the sole plate of at least one slide member which passes therethrough and is vertically displaceable relatively thereto within limits, the lower end of the slide member resting on the ski and the sole of the boot coming to lie on the upper end.

Safety ski-binding

In a heel-holding device for ski bindings in which a sole depressor equipped with a closing pedal is pivoted to the ski about a horizontal transverse shaft disposed behind the boot and is resiliently pressed onto the upper sole rim by a spring, the force of the spring being transmitted to the sole depressor by an interposed locking member which is pivoted to the ski parallel to the sole depressor, and in which the locking member is deliberately pivotable to a depressor-releasing position by means of a handle so that the sole depressor can assume its open position under the influence of a second spring that is weaker than the first spring, the transverse shaft of the locking member is disposed on the boot side of the transverse shaft of the sole depressor and the locking member is provided with a recess for receiving a latch member of the sole depressor, the recess being formed with a slide track and adjoining catch groove co-operating with the latch member.

Heel-holding device for ski bindings

In a method of automatically releasing a ski boot from a ski in case of danger, the force acting on the leg of the skier and the duration of application of said force are ascertained individually and represented as distances, the sum of said distances is compared with a predetermined distance representing a threshold value and, when such threshold value is reached, a connection between the boot and the ski is released. Apparatus for performing this method comprises at least one boot retaining member, a locking device for said retaining member, a threshold value switch acting on said locking device, a duration evaluating member, and a force receiver, the duration evaluating member being provided with a drive motor, such as a plate spring, which is operative when a predetermined minimum force is exerted on the force receiver.

Method and apparatus for releasing a ski boot from a ski

The skiing boot is connected to the ski by a separate soleplate, which in each of its forward and rear portions has at least one soleholder and to which the skiing boot is secured so as to be only arbitrarily adjustable. A plate holder is mounted on the ski and comprises a pivot bearing for the soleplate adjacent to the rear half of the latter. Adjacent to the rear end of the soleplate, the plate holder is provided with an element of a detent device, which in response to an overload in a vertical and/or horizontal direction releases the soleplate. Adjacent to the forward portion of the soleplate the plate holder is provided with a member for holding down the soleplate. The female detent element of the detent device is part of the plate holder. The male detent element of the detent device is provided on the soleplate. The soleplate is provided with raised side cheeks adjacent to the detent device. The male detent element, the spring acting on said male detent element, and the bracket for the rear soleholder are mounted on said side cheeks.
