ABSTRACT:
A heel holder arrangement of a safety ski binding has a sole holder which is pivotable about a first axis parallel to the surface of the ski between a position of locking the heel of a ski boot and a release position. Arranged behind the sole holder and pivotable about a second parallel axis is a retaining lever which at its upward end carries at least one retaining roller. The retaining roller co-operates both with a cam surface on the sole holder and also with a cam surface on a pivotable opening lever which is loaded by a compression spring. The cam surface on the sole holder includes a retaining recess in which the retaining roller is engaged when the sole holder is in the locking position. The spring is pivotable with the opening lever. The cam surfaces jointly determine the force-travel characteristic of the sole holder both in the event of safety release of the arrangement and also upon voluntary opening by actuation of the opening lever. A brace member is pivoted at a first end on the first axis and has its second end engaging the rear of the sole holder. At its first end the brace member also has a contact surface which can be engaged by the end of the compression spring as it is pivoted upon pivotal actuation of the opening lever. The brace member being pivoted about the first axis under the spring loading, it causes the sole holder to be pivoted into its release position after the movement of the opening lever allows the retaining roller to come out of the retaining recess of the cam surface of the sole holder.
