Abstract
The disclosure relates to a cross country ski binding having a triple-leaved hinge interconnecting a fixed toeplate and a heelplate detachably connected to the boot heel characterized in that as the boot is bent at the ball of the foot and lifted off the ski carrying with it the heelplate thereby lengthening the distance separating the latter from the toeplate, a yieldable spring-biased connection becomes operative to permit these elements to spread apart without materially retarding or otherwise interfering with the skier's freedom of lifting the boot and setting it back down again to initiate and complete the cross country glide while, at the same time, providing the lateral stability necessary for effectively edging the skis in the downhill mode. The invention also encompasses certain novel features present in a yieldable self-adjusting heel holdown subassembly.
