Binding system for a touring ski binding

Binding system for a touring ski binding, comprising a front jaw device and a rear jaw device for receiving a ski boot,

• wherein the ski boot has a heel part and a front foot part, wherein at least one web is arranged in or on the front foot part, wherein the web axis (Y) of the web runs perpendicular to the boot longitudinal axis (X), wherein the boot longitudinal axis (X) extends from the heel part to the front foot part,
• wherein the front jaw device comprises a holding device with a retainer and a locking system,
• wherein the retainer has a hook-shaped receptacle for receiving the web of the ski boot (4), which is aligned opposite the boot longitudinal axis (X), wherein the retainer at least partially surrounds the web and thus receives the web of the ski boot,
• wherein the locking system is configured to lock the web of the ski boot in the retainer rotatable about the web axis (Y),
• wherein the rear jaw device has a lever mechanism which is configured to fix the heel part of the ski boot,
• wherein in an ascent mode of the touring ski binding, the front jaw device is closed and the rear jaw device is open,
• wherein the retainer can lock the web of the ski boot rotatable and the locking system can secure the web against translation against the boot longitudinal axis (X), wherein the rear jaw device does not fix the heel part of the ski boot, so that the ski boot can be rotated about the web axis (Y),
• wherein in a descent mode, the front jaw device is open and the rear jaw device is closed, so that the retainer can receive the web of the ski boot, and the lever mechanism of the rear jaw device can fix the heel part of the ski boot, and
• wherein the rear jaw device with the lever mechanism exerts a contact pressure on the heel part of the ski boot along the boot longitudinal axis (X), so that the web is pressed into the retainer of the front jaw device, and the ski boot is thus secured against a translation against the boot longitudinal axis (X).
