  • Patent number: 4062563
    Abstract: On a support for attachment to a ski there is at least one ski-boot clamp that is movable from a boot-clamping to a boot-releasing position. A leaf spring has one end disposed in the clamp while means on the support hold the other end of the spring. The spring normally holds the clamp in clamping position but yields to a force sufficient to cause the spring to bend to permit the clamp to be moved out to boot-releasing position. The spring is curved transversely, with its concave side facing in the direction of the counter force that the spring exerts on the clamp while resisting movement of the clamp toward releasing position.
