The present invention relates to a heel unit (1) for a touring ski-binding, comprising, a heel member (10), wherein the heel member (10) comprises a reception bowl (12) for receiving the heel part of a ski boot and a biasing device (14) for biasing the heel unit (1) against a ski boot, and wherein the heel unit (1) is switchable between a starting position for receiving or releasing the ski boot and a snap-in position for holding the ski boot, wherein the heel unit (1) comprises a blocking means by means (20) of which the heel unit (1) can be blocked in the starting position, wherein the blocking means (20) is switchable between a blocking position and a non-blocking position.

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).

The invention relates to an automatic heel unit (1) for a ski binding, comprising a base (7) for fitting the automatic heel unit (1) on a ski and a heel downholder (3) for holding down a ski boot in a heel region of the ski boot. The heel downholder (3) is mounted so as to be movable in relation to the base (7). The automatic heel unit (1) has a holding configuration in which the heel downholder (3) is located in a holding position and may interact with the heel region of the ski boot that is held in the ski binding in such a manner that the heel region of the ski boot is held down in a lowered position. Furthermore, the automatic heel unit (1) has a step-in configuration in which the heel downholder (3) is located in a step-in position and the heel region of the ski boot is released by the heel downholder (3). The automatic heel unit (1) comprises a heel support structure (6), which is configured separately from the heel downholder (3), for supporting, in a direction that is horizontally transverse to the ski, the heel region of the ski boot that is held in the ski binding in the holding configuration of the automatic heel unit (1).
