Jr.Assistant: Mar, Michael Attorney, Agent or FirmInternational ClassA63C 9/08 (20060101)AbstractA method for achieving programmed release in ski bindings determines release criterial in order to minimize selected types of lower extremity ski injuries, the release criteria being formulated from biomechanical models and associated equations. Analog and digital control circuits compute the release variables from the biomechanical model equations and compare the variable values to the release criteria in order to precisely generate a release initiating signal. Loads measured in the ski binding drive the biomechanical model equations. The ski binding assemblies have a releasable binding for rigidly securing the ski boot to the ski with a release actuating element for releasing the ski boot from the binding upon occurrence of a release condition as determined by the associated control circuit.Other References
