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 release mechanism is provided for releasably connecting a strap to sports equipment. The strap is secured at a first end to the sports equipment and at a second end to the release mechanism. The release mechanism has a fastening part releasably connected to an engagement element. The engagement element interacts with a fastening part bail element that is pivotable about a pivot axle between a release position and an engaged position with the engagement element. The bail element can be secured in the engaged position by a securing element. The securing element and bail element are secured to the fastening part such that the distance between the pivot axle of the bail element and the securing element changes when a tensile load is applied to the bail element. The securing element releases the bail element when a defined release tensile force is exerted on the bail element.

A binding having a front plate (2), a front assembly (3) for immobilising the boot and capable of cooperating with the sole (81) of the boot (8), a rear assembly (6) for retaining the boot and capable of cooperating with a retaining lug (85) of the rear portion of the front sole and/or with the rear sole, the rear assembly being movable relative to the front plate in the vertical plane, and tensioning means (66) which act between the rear retaining assembly (6) and the ski and/or the front plate (2) and which are capable of tensioning the boot (8) on the binding (1) and enabling the heel to be raised freely. The front immobilisation assembly is mounted in a floating manner on the front plate about a transverse pivot axis (A3), the supporting point enabling the front end (81′) of the sole (81) of the boot.

The invention relates to a combination of a downhill binding or downhill ski binding, in particular a front jaw of the downhill binding, and a ski boot. The ski boot (10) comprises a rigid ski boot shell (11) and a sole (1) of the ski boot comprising a front end (1b) of the sole, a rear end of the sole, an upper side (1a) of the sole and a lower side (1c) of the sole. The downhill binding comprises a front jaw (20) and a rear jaw, wherein the downhill binding comprises a bearing structure (2) for the sole (1) of the ski boot. The bearing structure (2) has an apex (5) which has a distance (X1), in the longitudinal direction (X), from the front end (1b) of the sole held in the downhill binding of at least 28 mm and at most 34 mm, and wherein the apex (5) exhibits a perpendicular distance (Y2) from the upper side (1a) of the sole of the ski boot held in the downhill binding of 19 mm±2 mm in at least one point.

A release mechanism is provided for releasably connecting a strap to sports equipment. The strap is secured at a first end to the sports equipment and at a second end to the release mechanism. The release mechanism has a fastening part releasably connected to an engagement element. The engagement element interacts with a fastening part bail element that is pivotable about a pivot axle between a release position and an engaged position with the engagement element. The bail element can be secured in the engaged position by a securing element. The securing element and bail element are secured to the fastening part such that the distance between the pivot axle of the bail element and the securing element changes when a tensile load is applied to the bail element. The securing element releases the bail element when a defined release tensile force is exerted on the bail element.

The present invention relates to a release mechanism for a ski binding system, wherein the system comprises a ski shoe (20) wherein pins (11) moveable in each direction are arranged and at least one intermediate spring element (12), wherein the pins (11) are adapted to slide in a barrel (13) between a protruding and a retracted position. The system comprises a frame (2) with two vertical parts (3, 4) arranged on a ski, wherein each vertical part has an opening (5) each for receiving a pin (11) protruding sideways out of the ski shoe (20), two bails (7) with claws (8) at one end and brought together in a manipulator (9) at the other end, wherein the claws (8) and the manipulator (9) are adapted so that they can move synchronously into the openings in the opposite direction of the pins (11).

A binding for a touring ski, a Telemark ski or a cross-country ski having step in automatic locking. The binding includes a front retaining element to cooperate with the front sole of a boot, a rear retaining element to cooperate with the rear part of the front sole and/or the rear sole of the boot, a tensioning element to tension the boot on the binding and to enable the heel to be freely lifted, a tensioning link placed under and connected to a rear retaining stirrup, and a fixed or retraction stop to cooperate with the tensioning link so as to enable the rear retaining stirrup to move back, tensioning the tensioning element, when the heel of the boot exerts a downwardly directed pressure on the rear retaining boot situated in an idle position.

The invention relates to a combination of a downhill binding or downhill ski binding, in particular a front jaw of the downhill binding, and a ski boot. The ski boot (10) comprises a rigid ski boot shell (11) and a sole (1) of the ski boot comprising a front end (1b) of the sole, a rear end of the sole, an upper side (1a) of the sole and a lower side (1c) of the sole. The downhill binding comprises a front jaw (20) and a rear jaw, wherein the downhill binding comprises a bearing structure (2) for the sole (1) of the ski boot. The bearing structure (2) has an apex (5) which has a distance (X1), in the longitudinal direction (X), from the front end (1b) of the sole held in the downhill binding of at least 28 mm and at most 34 mm, and wherein the apex (5) exhibits a perpendicular distance (Y2) from the upper side (1a) of the sole of the ski boot held in the downhill binding of 19 mm2 mm in at least one point.

A binding system for a touring ski binding has a front jaw device and a rear jaw device for receiving a ski boot. In a descent mode, the front jaw device is open and the rear jaw device is closed, so that a retainer can receive a web of the ski boot, and a lever mechanism can fix a heel part of the ski boot. The rear jaw device with the lever mechanism exerts a contact pressure on the heel part of the ski boot along a boot longitudinal axis (X), so that the web is pressed into a hook system of the front jaw device, and the ski boot is thus secured against translation against the boot longitudinal axis (X).
