Abstract

This invention relates to a safety binding comprising a soleplate. The usual bindings may release the boot in response to a deflection of the ski caused by large waves. It is an object of the present invention to provide a binding which has a soleplate and which can store a larger energy and will not undesirably release the boot in response to a resilient deflection of the ski. Besides, the binding according to the invention provides for favorable kinematics as regards the movements which result in the release of a boot by a safety binding. For this purpose the invention provides a spring-biased heel holder and a soleplate, which is mounted to be displaceable in the longitudinal direction of the soleplate and is connected to the heel holder by a universal joint and which near that end which is remote from the heel holder is pivoted on an axis which is transverse to the soleplate.

Dependent claims

A safety ski binding comprising a soleplate, a toe holder, which is disposed at a forward end of the soleplate and cooperates with the toe portion of the boot, and a releasing device, which cooperates with the rear end of the soleplate and permits a release of the skiing boot, wherein the soleplate is pivoted to an adapter on an axis which is substantially transverse to the longitudinal direction of the soleplate and said adapter is adapted to be pivoted to the ski for a movement together with the soleplate about an axis which is at right angles to the plane of the soleplate, characterized in that a spring-biased releasing device (4) is adapted to be pivotally moved in vertically upward and lateral directions, the soleplate is mounted on a pivot (16) which is transverse to the longitudinal direction of the soleplate (3) and displaceable in said longitudinal direction, and the rear end of the soleplate (3) is connected to the releasing device (4) by an articulated joint, which is inseparable under operating conditions.
