| (54) | Method and apparatus for programmed release in ski bindings |
| (57) A method and apparatus for achieving programmed. release ski bindings is described
including formulation of biomechanical models and associated equations for determining
release cirteria in order to minimize selected types of lower extremity ski injuries.
Analog and digital (122') control circuits are also disclosed for computing the release
variables from the biomechanical model equations and comparing 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. Three embodiments
of ski binding assemblies are also disclosed including releasable binding means (310)
for rigidly securing the ski boot (316) to the ski (314) with a release actuating
element (318, 342, 334) for releasing the ski from the binding upon occurrence of
a release condition as determined by the associated control circuit (122'). |
