Abstract

A safety ski binding mounted on a member movable with respect to the ski but fixedly secured thereto. A release of the ski boot from engagement with the ski binding is initiated by forces applied to the heel holder. The heel holder is movable about both a vertical axis and a horizontal axis so that it is responsive to not only vertical and horizontal applied forces by the ski boot but also diagonally applied forces. A connecting lever-like element is movably secured to the housing for the heel holder and has one end thereof connected to a piston reciprocally movable in an open-sided cylinder on the housing. Thus, a reciprocal movement of the piston will initiate a pivotal movement of the connecting element. The other end of the connecting element is pivotally attached to a lock so that the lock is movable in response to a pivotal movement of the connecting element. The lock has a protuberance which projects over a lip on the heel holder to hold the heel holder in the boot holding position. Thus, a pivotal movement of connecting element in response to release forces applied by the ski boot to the binding will effect an unlocking of the heel holder and a release of the ski boot.
