Abstract: The heel holding device has a non-stretching tension member which is movable in every direction and constructed in the manner of a ribbon. The tension member is fastened at the ski by one end and can be fastened with its other end at a peg at the heel of the boot by means of a clamp. The tension member can be detached voluntarily by means of this clamp and can be pulled off the peg when a tensile force acts substantially in the direction of the boot sole. Two parts of a connecting piece are adjustably fastened to the tension member at a distance relative to one another. The two parts form a connecting piece which is constructed in the manner of a push button. A loop of the tension member remains in the closed state of the connecting piece, which loop leads to a lengthening of the tension member after the connecting piece is loosened when acted upon by increased tensile force, so that the boot heel can be lifted farther from the ski.

Abstract: The safety binding has a base part which is fixed with respect to the ski, a release part which is supported so as to be rotatable relative to the base part, and a guide jaw with clamping device for clamping the boot sole. In order to support the release part relative to the base part, this release part has at least three guide rolls which are supported so as to be freely rotatable and have circumferential grooves in which guide flanges engage, which guide flanges are downwardly and inwardly bent at the underside of the release part and engage in the guide grooves with their inwardly bent edges. Cut out portions are located between the guide flanges so that the release part can be freed from the guide rolls after a determined rotation relative to the base part. A release cam having a central locking recess and two symmetrically arranged control cams is securely connected with the release part.
