Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
286 words
A safety ski binding for releasably securing a ski boot having a ski boot sole to a ski, comprising; an automatic heel portion means for permitting forward release of the ski boot; a toe jaw arranged in spaced relation to said automatic heel portion means, said ski boot being received between said automatic heel portion means and said toe jaw; a laterally pivotable plate secured to said toe jaw and extending between said toe jaw and said automatic heel portion means a distance less than the spacing therebetween and from said toe jaw at least to a location beneath the ball of the foot of a skier when said ski boot is disposed in said safety ski binding between said toe jaw and said automatic heel portion means, said plate including an upwardly extending portion having a substantially vertical surface defining abutment means; stop means arranged on the underside of said plate in longitudinally spaced, confronting relation with said abutment means; counter support means fixed to the ski and arranged beneath said plate in non-contacting relation with the sole of said ski boot, said counter support means having a substantially vertical surface means engaging between said abutment means and said stop means for preventing movement of said plate along the longitudinal axis of the ski and for permitting lateral movement of said plate relative to said counter support means; bearing means cooperating with said plate for enabling lateral pivotal movement of said plate about a point longitudinally spaced from said counter support means; means for releasably fastening the plate to the ski, said fastening means comprising a spring-loaded locking means arranged forwardly of and cooperating with said plate for enabling lateral pivotal movement of said plate.
