A toe-piece of a ski binding for ski mountaineering has a base, a first jaw, a second jaw, an activating lever, a joint, a housing, and elastic means. The first jaw is provided with a first guide, and the second jaw is provided with a second guide. The activating lever is rotatably coupled to the base. The joint is activatable by the activating lever, which includes a first sliding element slidably coupled with the first guide and a second sliding element slidably coupled with the second guide, so that the activation of the activating lever causes, via the joint, the rotation of the first jaw and the second jaw. The housing is borne by the base. The elastic means are arranged in the housing so as to push the joint to wedge against the first jaw and the second jaw.

Toe-piece for a boot on a gliding board including a chassis affixed to the gliding board; a body movable on the chassis; a sole-clamp movable on the body; a lateral release mechanism including a first elastic mechanism to return the sole clamp to engagement with the boot; a vertical retention mechanism having a second elastic mechanism arranged to continuously exert a return force on the body to bring the sole-clamp toward the lower surface of the chassis, the return force pressing the sole-clamp on the boot; at least one cam kinematically inserted between the second elastic mechanism and either the chassis or the body, the cam being shaped to modify, in relation to the chassis, the direction of the return force exerted by the second elastic mechanism on the body to attenuate a variation in the pressing force when the sole-clamp is away from the lower surface of the chassis.

A mechanism for attaching, for example, a boot to a ski, that uses a sphere in cylinder geometry to enable release in a wide array of incremental directions and rotations.

The invention relates to an automatic front unit for a ski binding, in particular a touring ski binding, wherein the automatic front unit comprises a first retaining means and a second retaining means for retaining a ski boot in the toe region of the ski boot. This automatic front unit has a first retaining configuration, in which the two retaining means are in a retaining position, in which the two retaining means are at a first distance from one another, wherein the two retaining means can cooperate with the ski boot in the retaining position such that the ski boot is retained at the automatic front unit so as to be pivotable about an axis oriented horizontally in a transverse direction of the ski. Furthermore, the automatic front unit has a step-in configuration, in which the two retaining means are in a step-in position, in which the two retaining means are at a second distance from one another, wherein the second distance is greater than the first distance and wherein the ski boot is released from the two retaining means in the step-in position of the two retaining means, wherein the automatic front unit is adjustable from the step-in configuration into the first retaining configuration and back again. The two retaining means, in order to be adjusted from their step-in position into their retaining position and back again, are mounted so as to be movable in translation relative to one another along an adjustment path, wherein a region of the adjustment path that adjoins the retaining position of the two retaining means is oriented substantially horizontally.

A heel unit including a base comprising a fastening arrangement for fastening to a gliding board, a binding body, and coupling means arranged on the binding body. The coupling means engage with a heel portion of a gliding board boot in a downhill position of the gliding board binding to securely hold the gliding board boot on the gliding board binding. The coupling means protrude in a longitudinal direction from the binding body in the downhill position. The heel unit includes an Mz release mechanism to preload the coupling means into the downhill position so that, in the downhill position, the coupling means are freed from engagement with the gliding board boot upon action of a force exceeding a predetermined release force, and so that the coupling means move from the downhill position into a release position via rotational movement of the binding body about the release axis of rotation.

A toe-piece of a ski binding for ski mountaineering has a base, a first jaw, a second jaw, an activating lever, a joint, a housing, and elastic means. The first jaw is provided with a first guide, and the second jaw is provided with a second guide. The activating lever is rotatably coupled to the base. The joint is activatable by the activating lever, which includes a first sliding element slidably coupled with the first guide and a second sliding element slidably coupled with the second guide, so that the activation of the activating lever causes, via the joint, the rotation of the first jaw and the second jaw. The housing is borne by the base. The elastic means are arranged in the housing so as to push the joint to wedge against the first jaw and the second jaw.

A toe-piece of a ski binding includes rotatable first and second clamping members respectively provided with first and second jaws. First and second rotatable supports rotatably bear the first clamping member and the second clamping member, respectively. In a ski descent configuration, the first and second jaws can elastically retract if solicited by a tip of a ski boot. The first clamping member has a third jaw with a first pin, while the second clamping member has a fourth jaw with a second pin. Locking means are provided which when the ski boot tip is between the third and fourth jaws, the blocking means are activatable to block the third and fourth jaws in angular blocking positions in which the first pin is inserted in a first hole of a ski boot and the second pin is inserted in a second hole of the ski boot, making walking uphill possible.

A toe-piece for binding a boot on a gliding board, the toe piece including a chassis having a lower surface configured to be affixed to the gliding board; a body movably mounted on the chassis; a sole-clamp movably mounted on the body and capable of coming into contact with an upper surface and at least one lateral portion of a front or rear portion of the boot when the boot is engaged with the toe-piece; a lateral release mechanism including at least one first elastic mechanism acting on the sole-clamp to return it to a configuration of engagement with the boot; a vertical retention mechanism comprising a second elastic mechanism, distinct from the first elastic mechanism, arranged so as to continuously exert a return force on the body in order to bring the sole-clamp back toward the lower surface of the chassis, the return force producing a force pressing the sole-clamp on the boot when the boot is engaged with the binding; wherein the toe-piece includes at least one cam kinematically inserted between the second elastic mechanism and either the chassis or the body, the cam being shaped to modify, depending on the position of the body in relation to the chassis, the direction of the return force exerted by the second elastic mechanism on the body so as to attenuate a variation in the pressing force when the sole-clamp is away from the lower surface of the chassis.

A toe-piece of a ski binding has a base fixable to a ski, a first jaw, a second jaw, a first pin on the first jaw for inserting in a first lateral hole a ski boot tip, and a second pin on the second jaw for inserting in a second lateral hole opposite the first lateral hole in the ski boot tip. The toe-piece also has a first guide and a second guide on the base, each with a portion extending away from a longitudinal axis of the ski and another second portion extending towards the front of the ski. Two sliding elements on the first jaw engage slidably along the first guide and two sliding elements on the second jaw engage slidably along the second guide.
