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 safety valve intended to limit the pressure of a fluid contained in a vessel to which the valve is connected by a nozzle closed off by a flap-valve pressed against its seat by a spring acting on a first side of the flap-valve. The valve has two operating states; either the flap-valve is closed when the fluid pressure in the vessel acting through the nozzle on the opposite or second side of the flap-valve is below a pre-determined value or the flap-valve is open allowing fluid from the vessel to escape via an escape chamber in the valve when the pressure in the vessel is above the pre-determined value. A casing surrounding the spring is connected with the escape chamber by calibrated holes whereby the pressures in the casing and chamber are equalized. In addition to the spring, fluid pressure in the chamber acts on the first face of the flap-valve. When the flap-valve is closed, the fluid pressure in the escape chamber and casing is low.

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 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 boot comprises an upper, of which the stiffness is adjustable, and a strap surrounding the upper of the boot in the zone advantageously corresponding to the bottom of the leg.Means are provided to fix the strap on said upper.The strap comprises at least one zone of elastic deformation located between the said means for fixation on the upper, and means for controlling the deformation advantageously cooperating with the strap at least one either side of said zone of deformation.

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.

Abstract: A pair of skis are provided on their upper surfaces with respective mounting plates each carrying a treadle depressible by the boot of the user, the treadle overlying the bight of a yoke biased into a rising position be a pair of inclined shanks traversing the mounting plate. The extremities of the wire yoke carry blade-shaped brake elements which in the absence of boot pressure project downwardly beyond the runner surface of the ski and have confronting inner edges formed with notches coming to lie at the level of that surface, the width of the notch exceeding the thickness of the blade whereby the outer blade edges of the other ski can be received in these notches to hold the two skis together in back-to-back position with their runner surfaces contacting each other.

Abstract: A ski brake includes a pair of elongated levers each situated at one side of a ski and pivotable between an extended and an intermediate position laterally of the ski. A free end portion of the lever engages the surface on which the ski is supported when the ski becomes detached from the ski boot. A spring arrangement urges the respective levers toward their extended positions. The levers are further mounted on the ski for angular displacement between the intermediate position and a retracted position in which the free ends of the levers are located over the upper surface of the ski so as not to interfere with the proper operation of the ski. Another spring arrangement urges the levers from their retracted to their intermediate positions when the ski boot becomes detached from the ski.

Abstract: A ski brake for automatic release upon lifiting of a ski boot from the surface of a ski so as to prevent free flight thereof comprises a spring-loaded brake element adapted to reach downwardly below the bottom surface of the ski. A bent wire forms a bight which can be engaged by the ski boot and carries the brake element. A tread plate is disposed on the bight and is connected by another element, e.g. another bent wire, to the mounting structure for the ski brake.

Abstract: A ski binding having a locking device tripped electromechanically.The device includes an electromagnetic circuit comprising means producing a permanent magnetic field and a winding able to move in said field, the winding being connected to a member for retaining the locking member in order to move the retaining member into an unlocked position when a current is established or interrupted in the winding.

Abstract: A ski is provided with a heel clamp longitudinally slidable along the ski between a rear and a forward position and also pivotal on the ski between an up and a down position. A brake element is pivotal on the ski between a ready position extending parallel to the ski and a braking position extending generally normal thereto. A spring is provided for urging the brake element into the braking position. When a skiboot is securely held by the clamp it is in the down and rear position. When the boot is released and the clamp slides forwardly into the front position the abutments disengage to allow the brake element to assume the braking position. Similarly when the clamp pivots up into the upper position the brake element can assume the braking position. Pivoting of the clamp from the up to the down position automatically pushes the brake element back into the ready position.
