The invention relates to a heel-piece for binding a boot on a gliding board that includes a frame including a vertical extension; a body rotatably mounted about the extension; at least two rods supported by the body, extending on respective sides of the vertical extension, the two rods each having a free end to cooperate with a housing in the heel of the boot; and a holding mechanism for maintaining a spacing between the free ends of the rods. The vertical extension supports at least one contact zone fixed in relation to the frame. Each rod cooperates with a respective portion of the contact zone, specific to each rod. The contact zone is arranged such that a rotation of the body about the extension, from a descent configuration, causes an increased spacing between the two rods. The invention also relates to a binding system and a gliding board equipped with such a binding.

The present invention relates to a front unit of a touring binding, wherein the front unit comprises a bearing arrangement having a bearing element, wherein the bearing element is designed to hold a touring shoe on the front unit on a counter-bearing portion of the touring shoe so as to be pivotable about a transverse axis extending transversely to a glide board longitudinal axis, wherein a release path is defined on the bearing arrangement, along which path the counter-bearing portion of the touring shoe can exit the bearing arrangement, wherein the front unit further comprises a blocking portion designed to block the movement of the counter-bearing portion of the touring shoe along the release path when the front unit is in a blocked state, and to allow the movement of the counter-bearing portion of the touring shoe along the release path when the front unit is in a neutral state.

A snow ski has a longitudinal body defining a sole for gliding on the snow. The ski includes: (a) a platform slidably coupled to the body for sliding longitudinally relative to the body; and (b) a gripping element slidably and rotatably coupled to the body and rotatably coupled to the platform. The gripping element extends downward to penetrate the snow in response to the platform being slid rearward relative to the body. The gripping element retracts upward above the sole when the platform is slid forward relative to the body. First and second gripping elements may be disposed on opposing sides of the body. A locking mechanism selectively locks the platform at a forward position, in which the gripping element is retracted, one or more intermediate positions, or a rearward position in which the gripping element extends to penetrate the snow.

A ski-traction kit for retrofitting a ski is provided.

The invention relates to an automatic heel unit (1) for a ski binding, comprising a base (7) for fitting the automatic heel unit (1) on a ski and a heel downholder (3) for holding down a ski boot in a heel region of the ski boot. The heel downholder (3) is mounted so as to be movable in relation to the base (7). The automatic heel unit (1) has a holding configuration in which the heel downholder (3) is located in a holding position and may interact with the heel region of the ski boot that is held in the ski binding in such a manner that the heel region of the ski boot is held down in a lowered position. Furthermore, the automatic heel unit (1) has a step-in configuration in which the heel downholder (3) is located in a step-in position and the heel region of the ski boot is released by the heel downholder (3). The automatic heel unit (1) comprises a heel support structure (6), which is configured separately from the heel downholder (3), for supporting, in a direction that is horizontally transverse to the ski, the heel region of the ski boot that is held in the ski binding in the holding configuration of the automatic heel unit (1).

The invention relates to a system (1) for binding a shoe (2) to a foot rest (3) of a rowing boat, said shoe (2) having a sole (21) and said foot rest (3) being likeable to a plate having an underside (9) and a top surface (8). The main feature of a binding system according to the invention is that it comprises at least one mobile stop (6) projecting from the top surface (8) and a rigid actuating lever (4) projecting from the underside (9), and in that said lever (4) is connected to said at least one stop (6) in such a way that movement of said lever (4) causes said at least one stop (6) to move between a deployed position in which it becomes lodged in a recess (22) in the sole (21), and a retracted position in which it leaves said recess (22) and allows the shoe (2) to be detached from the foot rest (3).

A ski includes an elongated ski body having a bottom layer defining a bottom surface of the ski, a top layer defining a top surface of the ski, and a middle layer disposed between the bottom layer and the top layer, in which the middle layer includes a negative Poisson's ratio (NPR) foam material having a Poisson's ratio of between 0 and 1.

A ski boot for anchoring to a ski via a ski binding system includes a rigid foot enclosure including a bottom wall having a first mating surface. The ski boot also includes a sole block configured to selectively couple to the rigid foot enclosure. The sole block includes a second mating surface configured to mate with the first mating surface, the second mating surface defining a mating surface plane. The sole block also includes a traction surface configured to engage a ground surface, the traction surface defining a traction surface plane. The sole block is configured to support an insert fitting, the insert fitting defining at least one of a) a pair of opposed sockets or b) a pair of arcuate cut-away portions. A non-zero cant angle is defined between the mating surface plane and the traction surface plane.

The present invention relates to a system for a touring ski-binding comprising a front unit (5) and heel unit (1) comprising a heel member (10), wherein the heel member (10) comprises a reception bowl (12) for receiving the heel part of a ski boot, a biasing device (14) for biasing the heel unit (1) against a ski boot, wherein the heel member (10) is pivotally disposed around a pivot axis (S1), wherein the pivot axis (S1) runs horizontally, transverse to the longitudinal direction of the ski (L), and a stopper plate (40) for releasing a ski stopper, wherein the stopper plate (40) is switchable between an adjacent position and a protruding position, wherein the stopper plate (40) is configures to leave the adjacent position when the touring ski binding is released, wherein the heel unit (1) is switchable between a starting position for providing a blocking function and for receiving a ski boot, and a snap-in position for retaining the ski boot, wherein the heel unit (1) comprises a walking means by means of which the stopper plate (40) can be blocked in the adjacent position, wherein the blocking means (20) with respect to the pivot axis (S1) is switchable between a blocking position and a non-blocking position depending on the position of the heel member (1), wherein with respect to the downhill mode the front unit (5) in the climbing mode of the touring ski-binding is displaced to the front in the longitudinal direction of the ski (L), so that a ski boot present in the touring ski-binding cannot contact the heel member (10) of the heel unit (1).
