Abstract: A system for binding a boot to a ski in such manner as to permit the heel of the boot to be lifted from the top surface of the ski. The system includes complementary members for laterally retaining the boot on the ski, these members extending substantially longitudinally with respect to the boot, at least beneath the front thereof. One of the members is located beneath the boot and the other on the top surface of the ski, and the members have complementary shapes so as to assure their cooperation during all phases of movement of the skier's foot.

Abstract: A ski boot including a shell base with a sole on its bottom, and a calf, the calf being adapted to accommodate the leg of a skier and being pivotably mounted to the shell base along a first pivot axis. The shoe further includes at least one vertical extension extending from the shell base, the calf being pivotably secured along a second pivot axis on the extension.

Abstract: A slipper for a ski boot produced by injection of a foam mixture of plastic material between the walls of two socks placed upon a form set in a mold, the outer of the two socks comprising a very thin, extensible sheet having the same dimensions as the inner sock when the two are in unstressed condition.

Abstract: A safety binding for a ski including a body having a jaw for holding a ski boot and a support fixed to the ski. The support has a rear transverse face with two recesses therein, and a front transverse face. The body includes a transverse face having two projections thereon, each adapted to engage one of the recesses of the support. The recesses and projections define two lines of support converging at a point above the ski and disposed, respectively, on either side of the longitudinal plane of symmetry of the ski, so that the body can pivot along either one of the lines of support. A spring urges the rear face of a piston against the front transverse face of the support so that the rear traverse face of the support is urged against the transverse face of the body. The rear face of the piston includes two lines of reaction converging toward the ski.

Abstract: A safety binding for a ski the disengagement of which for the release of a skier's boot is controlled by a signal provided by an electrical circuit. The safety binding has a stress detection device located on or in a test member which serves as a connection member between the boot and ski.

Abstract: A system for binding a boot to a ski intended for the practice of cross-country skiing. A connection between boot and ski is provided at the front of the boot, while the heel of the boot is free to lift with respect to the top surface of the ski. Structure for laterally holding the boot on the ski is provided between the sole of the boot and the top surface of the ski, and comprises two pieces, one of which is fixedly arranged on the part of the sole corresponding to the plantar support zone of the metatarsal zone, while the other piece is fixed to the ski in the zone where the first piece abuts.

Abstract: A safety binding adapted to be mounted on a ski for holding a ski boot thereon, wherein one of the parts, jaw or part connected to the jaw, is applied on the support means at three points, namely an upper point disposed in the longitudinal plane of symmetry of the binding and two lower points of support symmetrical with respect to this plane, the points thus defining the two lines of support, disconnection being effected by pivoting either on one of the lines of support, or on the other.

Abstract: A safety binding adapted to be mounted on a ski comprising a one-piece jaw in which engages and is maintained one end of the sole of a ski boot, the jaw being urged under the action of a resilient device against two support lines. The support lines, viewed along the axis of the ski, converge towards the point located above the ski.

Abstract: A cross country ski boot comprises a sole of moulded plastics material having substantially the form of a rectangle elongated in the longitudinal direction in its central part. The sole presents, in the front plantar support zone, a central part of considerable thickness, with flat, relatively narrow lower surface, in contact with the top surface of the ski. This central part is divided into two by a longitudinal centering groove extending over the whole length of the central part of the sole and intended to cooperate with a rib of complementary shape provided on the top surface of the ski. On either side of the central part, the sole comprises two side portions whose thickness decreases towards the longitudinal edges of the sole, with flat or curved lower surfaces, inclined upwardly from the central part towards the longitudinal edges of the sole which are located at a level higher than that of the top face of the ski.

Abstract: A safety binding for a ski, includes a main circuit for providing a signal to control the release of the binding and thus the freeing of a user's ski boot. The binding includes at least one additional circuit for providing an electrical signal which is independent of signals produced during skiing and which is applied to at least one point of the main circuit to enable simple checking of the condition of the binding.

Abstract: A ski brake has a pair of ski elements flanking the ski and each formed by a pair of wires which in the braking position with the ski element projecting down below the bottom of the ski extend at an angle to each other, and which in the rest position extend parallel to the normal displacement direction of the ski and to each other. One of the legs of each of these elements is pivoted about an axis fixed on the ski and the other is pivoted about an axis which can be moved toward and away from the immovable axis on the ski for swinging of the elements up and down between the brake and rest positions. A spring is provided either in the form of a springy joint between the lower ends of the two legs or as a separate compression spring to urge the legs into the brake position. An actuator is displaceable from a raised or advanced position into a depressed position to move the brake elements into the rest position and is similarly urged into the raised or advanced position by the spring.

Abstract: A ski has a heel or toe clamp which is displaceable between a down position holding a skiboot on the ski and an up position freeing the skiboot from the ski. An elongated brake element is pivoted on the ski for movement between a rest position parallel to the ski and a braking position transverse to the ski and extending downwardly below the bottom surface thereof. This element carries a lateral projection which engages in a laterally open recess formed on the clamp or in a rail carried on the clamp so that as the clamp pivots into the up position it pivots the brake element into the braking position. The recess may have a laterally inclined camming surface that further swings the brake element from a position overlying the upper surface of the ski into a position spaced laterally from the ski on displacement of the element from the braking to the rest position.

Abstract: A ski brake apparatus is provided which comprises two brake arms each mounted on one side of the ski and arranged to swing under the action of a spring force into a braking position in which each brake arm partly extends under the bottom side of the ski. Each brake arm and the associated spring is integrally formed from the same spring material. Each brake arm comprises a prolongation perpendicularly bent-off and mounted onto the ski to form the swing axis. This axis is oriented parallel with the upper side and transverse to the longitudinal direction of the ski. The end of the prolongation opposite to the brake arm is bent to form a spring bracket. The end of this spring bracket is bent parallel to the swing axis and separated from this axis in longitudinal direction of the ski.

Abstract: A ski boot made in two parts comprising an upper and a lower part, which co-operate by means of at least one deformation area provided on one of the two parts. A resilient attachment has two states provided for controlling the deformation of the area, namely a first state in a position of the boot suitable for skiing, in which it ensures the locking, at least rearwards, of the upper part on the lower part, and a second state, in a position of the boot suitable for walking, in which by its sole operation it allows at least partial elimination of the co-operation between the deformation area provided on one of the parts with the other part, as well as elimination of the aforesaid locking operation.

Abstract: A ski brake has a pair of elongated braking elements which extend parallel to each other and are pivoted about their middle portions about a pivot axis extending parallel to the upper surface and transverse to the longitudinal direction of a ski so that these braking elements can pivot between a rest position parallel to the ski and a braking position transverse to the ski and digging into the snow under the ski. An actuating member or plate is displaceable toward and away from the upper surface of the ski and is linked to the upper ends of the braking elements so that its displacement toward the surface of the ski will swing the elements into the rest position. In addition this actuating member is provided with links or similar means which tend to swing the lower ends of the braking elements inwardly above the surface of the ski so that they do not project laterally from the ski during use thereof.
