<p>A safety ski binding wherein the heel holding assembly includes a holder which is pivoted with reference to the ski about a transverse horizontal axis when stepped on by the heel of a ski boot. The holder is overlapped by a pivotably mounted support for a retaining lever having a claw which normally engages one or more surfaces on a base which is secured to the ski to thereby hold the support in a locked position. The holder is also mounted on the base and supports a disengaging lever which is coupled to the base by a link and engages the retaining lever to prevent the latter's disengagement from the base while the holder pivots within a range of heel-retaining positions. A helical spring which operates between the support and the holder tends to resist the lifting of the heel when such heel is received in the holder. In the event of a fall, the holder is pivoted beyond a predetermined position and thereby enables the disengaging lever to permit or to cause disengagement of the retaining lever from the base. The two levers thereupon cooperate to automatically pivot the holder to a step-in position in response to expansion of the spring as soon as the claw of the retaining lever is disengaged from the base. The support can be pivoted with reference to the holder and base to permit intentional disengagement of the retaining lever.</p> |
