Abstract
Abstract In ski binding apparatus, cam surfaces are engaged by bearing surfaces movable with the ski boot arranged to afford lateral restraint yet allow the ski boot to move along the ski. A heel binding has inclined cam surfaces engaged by bearing surfaces movable with the ski boot to afford vertical restraint for the heel of the ski boot. The bearing surfaces pass the extremities of an associated cam surface to release the ski boot upon the application of a selected amount of lateral or vertical thrust to the ski boot in cooperation with a forwardly yieldable toe binding which allows the ski boot to slide forwardly for release at the heel, the toe binding having an adjustable force-applying means resisting forward movement of the ski boot to regulate the amount of thrust required to release at the toe and at the heel. An intermediate support between the toe and heel may also be utilized to provide lateral movement restraint for the ski boot and establish a pivot about which the ski boot will turn to reduce the strain on the leg. In an alternate form, a step-in carrier for the ski boot is releasably secured to the ski by toe and heel bindings together with an intermediate support for establishing a pivot for the carrier and ski boot between the toe and heel without altering or adding structure to the ski boot.
