A touring skibinding (1) comprises a support element (2) which can be fastened to the ski, a bearing element (3) with a skiboot reception (4) which is designed in such a way that the skiboot (5) can be mounted in the skiboot reception (4) such that the skiboot can pivot about a first pivot axis (S1) with respect to the skiboot reception (4) and a convex supporting surface (6) on which the skiboot (5) can roll, the bearing element (3) being connected to the support element (2) so as to be pivotable about a second pivot axis (S2) from an initial state into a pivoted state, wherein the skiboot (5) is moveable from a standing state, in which the skiboot (5) stands on the convex supporting surface (6), into a pulling state, in which the skiboot (5) is at least partially lifted from the convex supporting surface (6), wherein, starting from the standing state, the skiboot (5) is movable on the convex supporting surface (6) in the direction of the pulling state in such a manner that the skiboot (5) rolls on the convex support surface (6), wherein a pivoting movement of the skiboot (5) about the first pivot axis (S1) and of the bearing element (3) about the second pivot axis (S2) is effected simultaneously with the rolling process.

A fastening assembly for a ski crampon includes a hinge pin having a mounting portion and a securing portion. The mounting portion has a smaller dimension in a first direction and a larger dimension in a second direction, the first and second directions orthogonal to the longitudinal direction of the hinge pin. The securing portion has substantially the same dimension in the first and second directions. A mounting fastening portion defines a gap and an opening. The gap and the opening each extends substantially transversely to a ski longitudinal direction and substantially parallel to the ski surface. The gap receives the mounting portion of the hinge pin, which is inserted through the opening. The dimension of the opening in the ski longitudinal direction is larger than the dimension of the mounting portion in the first direction and smaller than the dimension of the mounting portion in the second direction.

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.

The present invention relates to a front unit (10) for a touring binding, which front unit is to be mounted on a sliding board and has a mounting surface pointing in the direction of a sliding board surface, which mounting surface defines a sliding board plane (E), the front unit (10) being adjustable between a downhill configuration and a climbing configuration, comprising a first holding device (20) which is designed to fix a front portion of a sliding board boot for downhill travel with the touring binding, in the downhill configuration of the front unit (10), the first holding device (20) being adjustable between an active position and a passive position, and the first holding device (20) being set into the active position in the downhill configuration of the front unit (10), and being set into the passive position in the climbing configuration of the front unit (10), and a second holding device (40), which is designed to secure a toe portion of the sliding board boot for ascent with the touring binding in the climbing configuration of the front unit (10), in such a way that the sliding board boot is pivotable about a hinge pin that is substantially in parallel with the sliding board plane (E) and substantially perpendicular to a longitudinal axis (L) of the sliding board, the first holding device (20) being arranged closer to the sliding board plane (E) in the passive position than in the active position. Furthermore, the present invention relates to a touring binding comprising the front unit (10), which touring binding further comprises a heel unit and optionally a brake assembly.

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).
