ABSTRACT:
A safety ski binding wherein the holding-down device for the heel of a ski boot constitutes the shorter arm of a two-armed bell crank lever the longer arm of which constitutes or carries one coupling element of a disengageable coupling. The other element of the coupling is provided on or forms part of a yoke which is pivotably mounted on a ski or on a part which is secured to the ski and is rigid with or movably supports a pivot member which defines for the bell crank lever an axis extending transversely of the skiing direction. The lever is pivotable about and is movable transversely of the axis of the pivot member, either with or relative to the pivot member. A helical expansion or compression spring is provided to oppose the disengagement of the coupling. Such disengagement takes place when the one coupling element is moved through a predetermined distance relative to the other coupling element, or vice versa, against the opposition of the spring; the shorter arm of the lever is then free to pivot away from the heel. The spring is located behind the pivot member, as considered in the skiing direction.
