Abstract: A ski binding has a cheek for engagement with the sole, or sole and upper, of a ski boot, and elongated ribs are mounted on the cheek by a bridging portion of less width remote from the ski boot, a resilient slip lining being engaged by deformation on the ribs and having opposed longitudinal edges positioned adjacent the bridging portion, the slip linings being of polytetrafluoroethylene or other material with a low coefficient of friction.

Abstract: A safety ski binding comprising a movable elongated plate pivotally and releasably mounted on the ski for supporting the ski boot. It has front and rear end means for holding the ski boot on the plate, resilient retaining means registering with one end of said plate and adapted to keep same in its normal position, and a fixed abutment member at the opposite end of said plate for retaining same on the ski. Said abutment member has curved and cooperating inclined faces that cooperate with a correspondingly curved registering end of said plate to cause self-centering of the plate.

Abstract: A safety ski binding comprises a movable plate for supporting a ski boot, and is mounted for pivotal movement in a plane parallel to the ski; toe-end and heel-end devices are adapted to retain the plate under normal skiing conditions against upward and lateral movements; the toe-end device comprises co-acting inclined and curved surfaces, and the heel-end device comprises a tilting arm pivotally mounted to a transverse pivot pin carried by a pintle mounted in turn for rotation about its axis perpendicular to the ski surface; spring-loaded members normally urge the tilting arm to its normal skiing, boot-retaining position; the plate is adapted to be released in all directions when subjected to excessive stress.

Abstract: A safety ski binding comprising a detachable, pivotally-mounted plate for clamping the ski boot at the toe and heel ends thereof, and toe-end and heel-end devices for releasably holding said plate to the ski. The heel-end device essentially comprises a lock-bolt pivotally mounted to a case pivoting in turn about a pivot member rigid with, and perpendicular to, the top ski surface. The pivot axis of this lock bolt is perpendicular to said pivot member and parallel to the top ski surface, and extends across the longitudinal axis of the ski. This arrangement further comprises resilient means enclosed in said case and adapted to retain both said lock bolt in relation to said pivoting case and said pivoting case in relation to its pivot member in their normal operative position.

Abstract: A pivoting support adapted to be secured to a ski for receiving the heel member of a ski boot safety ski binding arrangement, which comprises in combination a pivot means adapted to be adjustably secured to the ski; plate means adapted to receive the heel portion of the ski boot and rotatably mounted to said pivot means, and an aperture formed in said plate means and having said pivot means disposed therein. The contours of said aperture and said pivot means are respectively shaped to permit certain movements of said plate means in the longitudinal direction of the ski. The guiding surfaces formed on said pivot means are adapted to guide said plate in the longitudinal direction while holding said plate against movement in the transverse direction by interposition of resilient means between said pivot means and said plate.

Abstract: This safety ski binding with incorporated boot-supporting pivoting plate comprises for supporting the ski boot a pivoting plate adapted to rotate about a pivot member rigid with the ski and provided with boot retaining means, preferably at both toe and heel ends of the boot. These boot retaining means are movably mounted on said plate and held in their operative position in a predetermined area or amplitude of the permissible pivoting movement of the plate, any overstepping of said area or amplitude being attended by a release of the boot.

Abstract: A ski braking device adapted to be preset automatically by fitting the ski boot to the ski. It comprises essentially a pair of braking arms having a common transverse shaft. These arms are normally parallel to the top surface of the ski and their shaft is rigid with a crank arm pivoted to a longitudinally movable member associated with spring means and adapted to transform the movement of rotation of said shaft into a movement of translation of said longitudinally movable member against the resistance of a spring. This arrangement constitutes a knee action mechanism and the device can operate efficiently whether the ski is sliding downhill with the ski tip or the heel end first. Means for locking the device against operation for transport or other purposes are provided.
