Abstract: A ski binding having a heel hold-down member which releases the boot whenever an overload is applied thereto. An opening lever is mounted for pivotal movement about an axis secured to a pair of parallel upstanding bearing supporting members mounted to the upper surface of a ski. One arm of the operating lever extends rearwardly of the heel hold-down member and is longer than the other arm which extends generally toward the heel hold-down member. The long arm is connected to a strap and the short arm is operatively connected to a spring-loaded operating member for controlling the movement of the heel hold-down member during the releasing operation.

Abstract: A ski binding having a pivotal boot hold-down part engaging a ski boot sole. The pivotal hold-down part is biased into two separate positions on opposite sides of a dead-center position by a spring. One end of the spring has an operating member located at one end thereof and engages a guideway on the pivotal hold-down part. The housing for holding the spring and the operating member is supported on a pivot axis spaced from the pivot axis for the hold-down part. The position of engagement by the operating member with the guideway effects a defining of a dead-center position relative to the spaced pivot axes.
