A front unit for a touring binding, which is to be mounted on a sliding board and has a mounting surface that points in the direction of a sliding board surface and defines a sliding board plane, the front unit being adjustable between a downhill configuration and a climbing configuration, comprising:
- a first holding device which is configured, in the downhill configuration of the front unit, to fix a front portion of a sliding board boot to the touring binding for a descent, the first holding device being adjustable between an active position and a passive position, and the first holding device being set into the active position in the downhill configuration of the front unit and being set into the passive position in the climbing configuration of the front unit, wherein the first holding device is arranged closer to the sliding board plane in the passive position than in the active position;
- a second holding device which is configured to secure a toe portion of the sliding board boot, for ascent with the touring binding, in the climbing configuration of the front unit, 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 and substantially perpendicular to a sliding board longitudinal axis, wherein the second holding device comprises two arms which are pivotably mounted on a base of the front unit and have holding means which are configured to pivotally hold the sliding board boot in the climbing configuration of the front unit, and wherein an opening angle of the arms of the second holding device relative to one another in a starting configuration of the front unit is greater than in the downhill configuration of the front unit and/or the climbing configuration of the front unit;
- and
- a lever assembly comprising an opening lever and a deflection mechanism,
- wherein the opening lever has an actuating portion and is adjustable by means of the actuating portion between a downhill position, a starting position, and a climbing position and the lever assembly is configured to adjust the front unit between the downhill configuration, a starting configuration, and the climbing configuration by means of an adjustment of the opening lever between the downhill position, the starting position and the climbing position,
- wherein the deflection mechanism comprises a locking lever, which is formed in one piece with the opening lever or is immovable relative to the opening lever, and an adjusting lever which is connected to the opening lever and/or the locking lever and which is configured to transmit an adjusting movement of the opening lever to the second holding device in order to effect a movement of the arms of the second holding device relative to one another to modify the opening angle of the arms,
- wherein one end of the locking lever has a latching portion which is configured to engage with a complementary latching portion provided on the base of the front unit in the climbing position of the opening lever, in order to lock the second holding device in the active position, in the climbing position of the front unit, and
- wherein the opening lever is pivotably mounted about a swivel pin in such a way that the latching portion is able to pivot in front of and behind the complementary latching portion in relation to a direction in parallel with the sliding board longitudinal axis.
