Abstract: The shoe shall include at least one spring (R), notably a metal spring, set into the sole between an upper plate (2) extending as far as the back of the shoe and a lower plate (3) to cushion the shoe from shocks from the ground.

Abstract: The jig for facilitating the adjustment of a block under the sole of a cyclist's shoe, comprises a support (5) whereon the user's foot (6) is intended to be positioned. This support (5) is provided with an indentation (7) intended to receive the bulge corresponding to the articulation of the first metatarsal; a stop (19) is slidably mounted along the longitudinal direction of the support (5), this stop (19) being capable of being applied against one end of the foot (6), and provision is made for at least one graduation (G) on a longitudinal edge of the support, so as to cooperate with a specific zone (33) of the stop (19), to indicate the correct adjustment of the block (2) to be carried out, so that the articulation of the first metatarsal should occupy a specific position in relation to the axis (34a) of the pedal (34).

Abstract: The braking arms of the ski brake are carried solely by an operating pedal which is pivoted to the ski about a transverse axis. The corresponding control ends of the braking arms are elbowed so as to form a V, the point of which is directed away from the braking shoes and/or away from the top face of the ski. The control ends are rotatably mounted within bores having the same angular orientation and formed in the operating pedal. By means of an elastic plug applied against a flat face formed in each control end, the braking arms are caused to rotate upon completion of an upward displacement and the active ends of the arms are automatically restored to their inwardly withdrawn position above the ski.

Abstract: A toe-abutment member providing safety ski boot release in the event of a backward-fall movement combined with a twisting movement of the skier's leg comprises a fixed locking member having an inclined ramp and an abutment body pivotally mounted on a cross-pin. The jaw unit for retaining the toe end of the ski boot is movably mounted within the abutment body and carries a transverse rod which is applied against the ramp by means of a spring-loaded piston.

Abstract: A rear ski-binding element comprises a heel-holding member carried by a plate pivoted about an axis at right angles to the top ski face. Lateral flanges formed on the pivotal plate are each adapted to carry a lateral packing member. Each packing member has a resilient inner wall which is capable of outward elastic deformation under the action of engagement of a ski boot. The rear ski-binding element is thus automatically adaptable to ski boots having different widths.

Abstract: A pivotal control flap carried by the top section of one ski-braking arm is connected to an identical flap carried by the other braking arm by means of a top arcuate member. Each flap has two separate bores forming swivel-bearings respectively for the top section of the corresponding arm and for the respective leg of the arcuate connecting member. The angle made by the bores with respect to each other is such that the pivotal displacement of the two flaps under the pressure of the ski boot produces a movement of relative inward withdrawal of the bottom sections of the braking arms when they are in the raised position.

Abstract: A ski brake comprising two pivotal arms having intermediate elbowed portions pivotally mounted in fixed bearings about an axis transverse to the ski, an operating pedal and a spring for restoring the pivotal arms to their braking position. A flexible and resilient metallic strip provides a connection between the control ends of the braking arms, is secured to an operating pedal actuated by the ski boot and is subjected to the action of a restoring spring and traction member. The ends of the resilient strip are fixed in cylindrical sleeves which are rotatably mounted on the control ends. When a boot is in position within the safety ski binding and the ski brake is therefore in a standby position of withdrawal above the ski, the resilient strip has a flat configuration and is located in practically the same plane as the traction member, thus preventing the appearance of a parasitic stress which would otherwise be liable to interfere with the operation of the ski binding.

Abstract: The toe abutment member comprises a jaw unit pivotally mounted on the ski and consisting of two lateral arms adapted to cooperate with the front portion of the ski boot in order to maintain the boot in the axis of the ski, and a resilient device housed within the body of the abutment member for locking the arms in the boot-retaining position with a predetermined stiffness of release. The toe abutment member essentially comprises in addition a feeler member placed in contact with the front portion of the ski boot and adapted to cooperate with the resilient device to reduce the stiffness of release at the time of a forward-fall position and/or when an axial thrust is exerted on the ski boot.
