ABSTRACT:
A safety ski binding having a base plate secured to a ski and a push rod movably mounted on the base plate and adapted to be displaceable against spring force along the axis of symmetry of the base plate. The axis of symmetry extends in the longitudinal direction of the ski. The push rod is adapted to be held in position by a tensioning device. A pair of rollers is carried by the push rod and the base plate, one roller being movable toward and away from the other roller. The axles of the rollers extend transversely to the longitudinal axis of the push rod and parallel to the base plate. The bottom of the heel portion of the ski boot has a longitudinally extending groove therein. The upper surface of the base plate has in the central portion thereon an upstanding truncated cone adapted to be received in the groove in the heel of the ski boot. The surface of the truncated cone engages the side walls of the groove in the heel of the ski boot and permits a rotational movement of the heel about a vertical axis relative to the base plate during a release of the ski boot from the ski.
