ABSTRACT:
A ski binding is provided for use both in alpine skiing and cross-country skiing and can be quickly converted between two different conditions for use in either type of skiing. A longitudinally extensible boot plate is selectably securable to the bottom of a ski boot and has laterally flexible spring bars pivotally and releasably connected to laterally extending pin members on a toe piece anchored to the ski so that the boot plate can move pivotally about an axis extending transversely of the ski. To prevent pivotal movement of the boot plate about the toe piece during alpine skiing, a heel piece is provided to hold the trailing end of the boot plate in closely adjacent relationship with the ski. The heel piece is selectively movable so as to release the trailing end of the boot plate for cross-country skiing and a heel lift plug can be incorporated into the heel piece to facilitate cross-country skiing. In addition, resilient means are provided on the heel piece which can be positioned beneath the trailing end of the boot plate to bias the boot plate upwardly to assist a skier in climbing uphill.
