The invention relates to a ski binding including a front jaw and a rear jaw for holding the sole of a ski boot. The front jaw includes a base, via which the front jaw can be connected to a ski, a first holding device for connecting the boot to the ski at the front end of the boot for ascending, and a second holding device for connecting the ski boot to the ski at the front end of the boot for descending. The second holding device exhibits a first configuration for descending, in which the second holding device is in contact with the front end of the sole of the ski boot, and a second configuration for ascending, in which the second holding device is out of contact with the front end of the sole of the ski boot.

A toe piece for a device for fastening a boot on a sliding board, having a base (130; 3) intended to be fixed to the sliding board, two lateral jaws (101; 8, 9), each mounted to be rotationally mobile on the base (130; 3) about a substantially vertical rotation axis (103; 10, 11), so as to occupy a closed position to hold a boot and a separated position to release or receive a boot, and a pusher (110; 35) having two lateral trig surfaces (114; 24, 25) each cooperating with a respective ramp (104; 22, 23) of each jaw (101; 8, 9), this pusher being linked to the base by a trig spring (112; 36), and two links (120; 28, 29) each linked to a jaw by a first lateral axis (123; 14, 15) and linked together by at least one central axis (125; 32).

System for a touring ski-binding comprising a front unit and heel unit comprising a heel member, wherein the stopper plate is switchable between an adjacent position and a protruding position, wherein the stopper plate is configures to leave the adjacent position when the touring ski binding is released, wherein the heel unit 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 comprises a walking means by means of which the stopper plate can be blocked in the adjacent position, wherein the blocking means with respect to the pivot axis is switchable between a blocking position and a non-blocking position depending on the position of the heel member, wherein with respect to the downhill mode the front unit in the climbing mode of the touring ski-binding is displaced to the front in the longitudinal direction of the ski, so that a ski boot present in the touring ski-binding cannot contact the heel member of the heel unit.

A front jaw (1) of a safety ski binding with a base plate (3) and a housing (2) with a housing upper part (2a) as well as with sole holders (5) pivotable about bolts (6, 6) forming vertically extending axes and having front and rear segments, the sole holders, at their front segments, receiving the bolts (6, 6) in bores (5a, 5a) and, at their rear segments, cooperating with the sole of an inserted ski boot.

The sole holders (5), at their front segments, are mounted on the housing upper part (2a) in a ball-joint-like manner, so that they are movable upwards over their rear segments by tilting the bolts (6, 6), wherein each bolt (6, 6) projects through an elongated hole (11) extending in the ski longitudinal direction, formed in the base plate (3) and having front and rear ends (11a, 11b), and below the elongated hole (11), is pressed towards the front end (11a) of the elongated hole (11) under the action of a spring (14), wherein the rear end (11b) forms a stop limiting the extent of tilting the bolts (6, 6).

The toe-piece of a ski mountaineering binding comprises: a first jaw and a second jaw rotatably coupled with a base fixable to a ski; a first hooking element borne by the first jaw and having a first tip for inserting in a first lateral hole of a ski boot and a second hooking element borne by the second jaw and having a second tip for inserting in a second lateral hole of the ski boot when the toe-piece assumes a configuration of an inserted ski boot. The toe-piece is configured so that the first hooking element is inserted in a first seat in the first jaw to enable a roto-translatory motion between a retracted position when the boot is aligned to the longitudinal axis of the ski, and a plurality of possible advanced positions when the ski boot temporarily misaligns with respect to the longitudinal axis of the ski.

boot on a sliding board, having a base (130; 3) intended to be fixed to the sliding board,

two lateral jaws (101; 8, 9), each mounted to be rotationally mobile on the base (130; 3) about a substantially vertical rotation axis (103; 10, 11), so as to occupy a closed position to hold a boot and a separated position to release or receive a boot,

and a pusher (110; 35) having two lateral trig surfaces (114; 24, 25) each cooperating with a respective ramp (104; 22, 23) of each jaw (101; 8, 9), this pusher (110; 35) being linked to the base (130; 3) by a trig spring (112; 36)

and two links (120; 28, 29) each linked to a jaw (101) by a first lateral axis (123; 14, 15) and linked together by at least one central axis (125; 32).

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).
