Front unit for a touring binding

A front unit for a touring binding, comprising:

• two lateral bearing portions arranged on a ski transverse axis that extends substantially orthogonally to a ski longitudinal axis and parallel to a ski plane, wherein, when the front unit is in a closed position, the two lateral bearing portions are configured to engage lateral counter bearing portions of a ski boot to hold the ski boot on the front unit so that the ski boot can pivot about the ski transverse axis;
• and
• a longitudinal positioning portion on which the ski boot can be supported in an entry position, wherein the counter bearing portions are positioned, with regard to their position along the ski longitudinal axis, in a position for engagement relative to the bearing portions,
• the front unit being shiftable between an open position and the closed position, wherein:
• in the open position of the front unit, the bearing portions and the counter bearing portions are disengaged, the longitudinal positioning portion is secured relative to the bearing portions, and the longitudinal positioning portion is put in a first position for supporting the ski boot in the entry position, the longitudinal positioning portion being locked in the first position in the open position, and
• in the closed position of the front unit, the bearing portions and the counter bearing portions are engaged and the longitudinal positioning portion can be moved relative to the front unit or to the bearing portions with the ski boot in every step, and
• wherein the longitudinal positioning portion is preloaded in a direction of the first position by a resilient means.
