Abstract: A ski binding for cross-country skiing comprises a locking lever provided with a nose for locking the toe end of the ski shoe in position and also with an extracting appendage. During disengagement of the ski shoe from the binding, the extracting appendage exerts an upwardly directed thrust beneath the toe end of the ski shoe, thus facilitating the disengagement operation.

Abstract: The cross-country skiing assembly comprises a ski shoe and a ski binding for fixing the shoe on a ski. A toe block at the front end of the shoe has a fastening contour which is capable of cooperating with a complementary fastener on a shoe-retaining stirrup of the ski binding. A spring-loaded locking and releasing lever of the ski binding permits automatic positioning of the ski shoe by downward engagement. The shoe-retaining stirrup is pivotally mounted on a cross-pin which is adjacent to the front end face of the toe block.

Abstract: The toe abutment member of a ski binding is adapted to cooperate with a ski boot provided with a sole having a truncated front end and a toe-cap extension in overhung relation to the truncated front end. The abutment member comprises a feeler element placed directly beneath the toe-cap extension of the ski boot in close proximity to the toe-cap extension under normal skiing conditions. In the event of a forward fall, the feeler element undergoes a vertical displacement in the downward direction under the thrust exerted by said extension while producing a reduction in inherent stiffness of release of the toe abutment member.

Abstract: The control ends of two pivotal braking arms have elbowed extensions rotatably mounted in bearings provided on or within an operating pedal. In the active braking position of the pivotal arms, the axes of the elbowed extensions form a V having a downwardly-directed point and the braking ends of the pivotal arms are outwardly displaced with respect to each other on each side of the ski. In the withdrawn position, the braking ends are close together and set back with respect to the sides of the ski. However a tension spring tends to produce a pivotal displacement of the operating pedal with respect to the pivotal arms to an angular position such that the braking ends are spaced at a sufficient distance to pass on each side of the ski.

Abstract: A ski brake is provided with two braking arms pivotally mounted in bearings disposed transversely with respect to the ski. The braking arms are downwardly inclined towards the interior of the ski and joined together by means of a resilient stirrup-piece located above the ski and capable of undergoing resilient flexural deformation in its own plane. The stirrup-piece is connected to the braking arms by means of pivot-pins in the form of rivets, the axes of which are located at right angles to the plane of the stirrup-piece.

Abstract: Under normal skiing conditions, two lateral arms of a jaw unit cooperate with the toe end of a ski boot in order to maintain the boot in the axis of the ski and are held in position with a force designated as the inherent stiffness of release. When an excessive twisting effort is exerted on the skier's leg, the arms both move in a transverse direction with respect to the ski in order to permit lateral disengagement of the boot. A toe abutment feeler member is in contact with the front end of the boot and cooperates with a spring-loaded piston unit in order to reduce the inherent stiffness of release as well as resistance to torsional disengagement in the event of a forward fall of the skier and/or of an axial thrust exerted by the boot, thus achieving considerably enhanced safety.

Abstract: This toe-fitting for safety ski binding is of the type intended for operating in conjunction with a boot supporting device and includes a boot supporting plate movable across the ski and adapted, during its movement, to cause through a cam mechanism the translation along the ski axis of a slide controlling the release spring in order to reduce the resistance thereof to the ski boot release movement, the release threshold being thus kept to a substantially constant value notwithstanding the presence of dirt, mud or other unevennesses on the bottom surface of the boot sole.

Abstract: This ski brake comprises two pivoting brake arms disposed symmetrically on either side of the ski and having each an operative portion movable between a lower braking position and a raised retracted inoperative position, the opposite ends of the brake arms carrying a control pedal hinged to bent extensions of the opposite ends of the brake arms. When the pivoting brake arms are in their retracted inoperative position above the ski top and the pedal is pressed against the ski top, the axes of the bent extensions form an obtuse angle having its vertex directed away from the brake shoes carried by the operative portions of the brake arms. These brake arms are on the other hand so shaped that when inoperative the brake shoes are retracted inwards of the ski edges, above the ski top. When the ski boot is lifted off the brake control pedal, the latter is urged by spring means to its raised position while both brake shoes are divaricated and lowered to their operative position clear of the ski edges.

Abstract: A retractable ski brake includes a pair of pivoted brake arms disposed symmetrically on either side of the ski and freely journaled on the ski top surface in bearings, the operative ends of the brake arms being adapted to be raised and retracted inwards of the ski so as not to protrude from the side edges thereof when inoperative. The opposite ends of these arms are interconnected by hinge means through a flexible, suitably shaped portion of the same metal wire constituting the brake arms. A strap fastened to clamps rotating about these opposite ends forms a control pedal, and the hinge means is anchored to one end of resilient return means normally urging the brake arms to their operative position and the control pedal to its raised position, these positions being obtained when the ski boot is lifted off the ski.

Abstract: A safety ski binding includes an end piece engageable with a ski boot and horizontally pivotable on a body rotatably mounted on a pivot member carried on the surface of a ski for vertical pivotability with respect to the ski. The vertical pivot member includes two diametrically opposed cam faces movable in the longitudinal direction of the ski, each of the cam faces being engaged by a separate piston while being urged by a common spring. The end piece is adapted to move one of the two pistons away from the corresponding cam surface on vertical movement of the end piece. A modified embodiment of the invention utilizes a single piston and the spring controls the release of the ski boot under both side torsion stresses and vertical movements of the ski boot end associated with the binding when they exceed predetermined and adjustable limit values.

Abstract: A ski brake fitted on the heel-retaining unit of a ski binding has two rotatable arms actuated by a battery-powered reversible electric motor which is engaged with an arm-actuating mechanism. A double-throw contactor associated with the actuating mechanism co-operates with a spring-loaded pusher. When the ski boot is inserted in the ski binding, the pusher is moved away from the contactor and the motor produces a pivotal displacement of the arms to their inactive position. When the boot becomes detached from the binding, the pusher spring applies the pusher against the contactor, the motor is started-up and produces a pivotal displacement of the arms to their active braking position.

Abstract: A jig for drilling and/or tapping in a ski top the holes necessary for fixing a safety ski binding thereto comprises a frame adapted to be temporarily secured to the ski and consisting of a pair of parallel elastic rods along which a pair of slides are movable and adapted to be locked in the desired positions; each slide carries the necessary number of guide sockets for the bit and/or tap, the socket length and position on the frame being such that in combination with shoulder means provided on the bit and/or tap the depth of penetration of the bit or tap into the ski cannot exceed a predetermined value.

Abstract: In this assembly comprising a ski boot and a safety ski binding for the heel end of the ski boot, adapted to cooperate with the heel end by means of a heel clamping member, the rounded rear end of the upper extends beyond the heel end of the sole, and a recess is formed between the upper and the sole, the heel clamping member comprising a lever adapted to be depressed by the rear end of the upper for closing this lever upon the edge of the sole when the ski boot is being fitted into the binding, the free outer operative end of the lever being thus caused to penetrate into the recess, so that the device can safely be used even with ski boots having their heel edges bevelled as a consequence of the wear thereof.

Abstract: This combined ski boot and safety binding comprising a recessed boot receiving a binding case is adapted releasably to cooperate with a complementary member fastened to the ski, the case comprising pistons responsive to resilient return springs, the pistons being provided with transverse rods engaging cam contours formed on upstanding lateral lugs rigid with the complementary member; the boot is provided with a pivot member formed with opposite flat faces adapted to actuate the pistons when the boot is lifted and/or rotated as a consequence of a forward or backward fall, or in case of abnormal torsion stress, so as to release the boot and the case from the complementary member.
