Knee twist sensing ski binding

摘要

A ski binding for preventing twist-type fractures of the lower leg has an elongated sensor element extending between the knee region of the skier and the ski boot and responsive to angular displacement of the knee relative to the foot so as to release a locking mechanism interconnecting the boot to the ski when excessive twist between the foot and the knee is detected. This sensor element can comprise a Bowden-type cable whose core projects more or less from the sheath as the leg is twisted. Alternately a nontwistable but otherwise flexible element extending from the knee to the latch in the boot is provided which operates the locking mechanism securing the boot to the ski.
