摘要:
A braking device for a gliding board, such as a ski, that includes a plate adapted to be fixed on an upper surface of the gliding board; two braking arms movable between a gliding position and a braking position; and two flanges, each guiding a braking arm. Each flange is rotationally movable in relation to the plate about separate axes of rotation.

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.

Latching apparatus for a ski brake that has three elements: at least one braking element journalled on a base plate and movable between an active position, in which the braking element projects under the sole of the ski, and an inactive position, in which the braking element is raised with respect to the ski; an elastic system biasing the braking element toward the active position; and activation means for activating the braking element to move from the active to the inactive position in response to downward pressure from a boot on the activation means. The latching apparatus is a removable bar positioned either, between two of the movable elements of the brake or between the braking element and an element integral with the ski, to lock the braking element in its inactive position. The latching apparatus also includes an extension element, extending vertically above the bar, and positioned in front of the binding so as to block the insertion of the boot into the binding. In addition, the extension element is positioned between lateral edges of the ski above the sole of the ski so as to permit easy access to the sole of the ski and the edges of the ski for easy maintenance.
摘要:
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.

A helmet for protecting the head having a rigid shell that includes a body, made of an expanded polystyrene type of material, for example, molded over an outer skin, the shell further including a rigid arch device, the arch device includes a headband applied to the shell, each of the ends of the headband being equipped with an ear-covering part. The ear-covering parts can include a foam cushion covered by fabric. The arch device can have two wings which cover the ear-covering parts and which extend the headband and which can also be provided with a chin guard joining the two wings together. The arch device can be either glued or releasably attached to the shell.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
An assembly of a boot and a binding for a gliding board, such as a ski, as well as the boot and binding themselves. The binding has a movable mechanical mechanism for enabling a modification of the release threshold of the binding at will. The boot has a local reference which differs according to whether the boot is for the right or left side. The binding has movable sensors and a linkage to affect the release threshold of the binding. The reference of the boot determines the side of the jaw for which the release threshold is modified.
摘要:
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 Δt 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 Δt 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: Δt>1 s; 0.75×St≧Sr(Δt)≧0.5×St, with the theoretical release threshold St being determined as a function of the skier's parameters in conformance with ISO standards. In a particular embodiment, the release principle, which defines the actual release threshold as a function of the duration, Sr (Δt), is of the exponential decrease type: Sr(Δt)=a+exp[(b−Δt)/c]; whereby a, b, and c are parameters.
