Abstract: A safety binding device for binding a boot on an alpine ski including a releasable retaining mechanism of the mechanical, hydraulic, viscoelastic type, which actuate a release as a function of the forces to which the boot is subjected and as a function of the duration ?t of the application of such forces. The release action occurs as soon as the magnitude of the force is greater than an actual release threshold, Sr, which is dependent upon the duration ?t of the application of force, such that if duration is greater than one second, the actual release threshold is between 50% and 75% of the theoretical release threshold, St, whereby: ?t>1 s; 0.75×St?Sr(?t)?0.5×St, with the theoretical release threshold St being determined as a function of the skier's parameters in conformance with ISO standards.

Abstract: A method and a device for controlling the connection between a user and a gliding or rolling apparatus on which the user is retained by a releasable retaining system, i.e., such as between a skier and ski by means of a ski binding. According to the method, the values of at least two flexion and torsion angles between the user's upper leg and lower leg are measured and the values of these angles in relation with the angles that indicate a critical posture of the user are considered, and the release of the retaining system is caused if the angle values measured exceed the indicative values. The device includes a member for measuring at least two angles and a processing circuit in relation with a table of indicative values.

Abstract: Goggles having a frame with two lateral edges, a shield borne by the frame, and a tie for retaining the frame on the user's head which is attached to each of the lateral edges of the frame. The tie for retaining the frame has a flexible cord located at each of the ends of the tie, each of the cords being connected to the frame by two upper and lower pull points separated along a lateral edge according to an upper cord strand and a lower cord point, and a return element sliding along the cord to allow the respective lengths of the upper and lower cord strands to be modified.

Abstract: A retaining element for retaining the front of a boot sole on a ski. The element includes a jaw carried by a body which itself is mounted on a mounting base. The mounting base has a front zone that supports the body, and a rear zone positioned lower than the front zone. The retaining element can accept ski boots having a thicker sole.

Abstract: The invention relates to a boot support device on a gliding board such as a ski. A support plate translationally movable along a transverse direction of the ski is overlaid by a support element of the boot that is rotationally movable about a longitudinal axis with respect to the support plate. A reverse construction is possible, the goal being to combine a translational displacement and a rotational displacement.

Abstract: A binding element adapted to retain the end of a boot. It includes a body that bears on a jaw. The jaw is vertically movable, and its movement is transmitted to the return spring of the jaw, which constitutes a compensation for a backward fall. The sole of the boot is pinched between a support plate and sole-tightener of the jaw. The support plate is movably mounted about a horizontal and longitudinal axis so that a twisting of the boot causes an elevation of the jaw and thus, activates the compensation mechanism.

Abstract: An assembly of two retention elements of two boots of a skier on two skis. Each retention element has a movable retention jaw, a return spring of the jaw, a transmission linkage of movement between the retention jaw and the spring, an adjustment mechanism acting on the transmission linkage to modify in a differential manner the release threshold of the jaw depending upon whether it displaces on one side or the other with respect to its aligned position and a movable manipulation button accessible from the exterior to control the adjustment mechanism.

Abstract: A retention element of a boot on a gliding board, particularly an alpine ski including a body, a base, a jaw for retaining the boot, likewise including a compensation mechanism to lower the return force that the spring exerts on the jaw. The support plate is movable to rock laterally around a longitudinal rocking axis, the support plate being supported on each side of the rocking axis on movable linkage assembly with the compensation mechanism, the rocking axis of the plate being movable along a vertical direction over a limited amplitude, and an elastic return device elastically returns the plate to the raised position.

Abstract: The invention relates to an assembly of a boot and a retention element of the ski boot. The boot has at the level of its tip a local asymmetry, that the retention element has a specific and symmetrical elastic retention element adapted to cooperate with the asymmetric zone in a manner such that the boot is freed more easily on one side than on the other. The invention relates also to a retention element and a boot considered alone, and to a pair of boots whose tips are symmetrical to one another.

Abstract: The invention is related to a binding element for alpine skis including a base connected to the ski, a body mounted on the base, a boot retention jaw borne by the body, an energy spring housed in the body to elastically oppose the opening movements of the jaw in response to biases of the boot, and a support plate on which the sole of the boot rests. The support plate is configured for being mobile in a rocking motion, and a linking arrangement, sensitive to the rocking motions of the support plate, connect the support plate to one of the mobile members of the binding element to reduce the resistance force that the boot must overcome in order to be released by the jaw in response to a rocking bias exerted on the support plate.
