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 front jaw for a touring ski binding, includes a base and at least one recess or transit opening in the base. Lateral sole retainers lie opposite each other in relation to a longitudinal axis of the front jaw each include a boot retainer pin and, in a pivoted-in state, co-operate with bearings formed on a ski boot, defining a pivoting axis for the boot extending substantially transverse to the longitudinal axis of the front jaw, and are adjustable between the pivoted-in state, where the bearings of the boot engage the boot retainer pins, and a pivoted-away state where the bearings of the boot are not engaged with the boot retainer pins; spring elements for tensioning the lateral sole retainers; a tensioning lever for moving the sole retainers from the pivoted-in state to the pivoted-away state to release the ski boot from a downhill skiing position or a walking position.

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 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).
