ABSTRACT:
A combination of a ski boot and a releasable ski binding which attaches the boot to a ski. The binding includes first connecting portion secured to the ski, second connecting means secure to the boot, and a plunger combination for releasably coupling the first and second connecting portions so that the boot may release from the ski in the forward, backward or lateral directions. The coupling combination includes a pair of plungers aligned in a fore-and-aft arrangement which engage respective spaced sockets. A device is provided for temporarily withdrawing one of the plungers from its engaged socket to permit separation of the first and second connecting portions, and therefore separation of the boot from the ski, without load. The ski boot includes a living hinge in the sole to facilitate walking in the boot. The boot may be locked or unlocked to permit pivoting of boot parts about the living hinge. The boot also includes front and rear cuffs, and a releasable strap securing the two cuffs together which, under predetermined rearwardly-directed load conditions, separate the two cuffs and permits free movement of the rear cuff. The resistance of the ski boot to forward and rear lean is controlled by a pair of oppositely directed springs secured to the front cuff.
