  • Ski binding having a dynamically variable upward heel release threshold
    Patent number: 7810833
    Abstract: A ski boot binding securable to an alpine ski. The binding includes a heel unit having a base heel release threshold in a direction perpendicular to the upper surface of the ski to which the binding is attached. The heel unit includes a compensation mechanism that dynamically changes the base heel release threshold as a function of force conditions encountered by the ski during skiing.

  • Alpine ski binding having release logic for inhibiting anterior cruciate ligament injury
    Patent number: 7762572
    Abstract: An alpine ski binding system for releasably securing a ski boot to a ski. The binding system includes a secondary toe release that provides an attenuated release threshold under lateral shear loading conditions that can cause anterior cruciate ligament injuries. The secondary toe release responds to a trigger that senses the lateral shear loads applied to the inside (medial) afterbody of the ski and triggers the secondary toe release to release the boot at an attenuated release torque. Lateral shear loads applied to the ski along the leading (medial) forebody and along the entire outside (lateral side) of the ski substantially do not cause the trigger to trip.
