Rear portion of a ski mountaineering binding

A rear portion of a ski mountaineering binding, comprising:

• a base which is fixable to a ski;
• a turret which is borne by the base and which is rotatable with respect to the base in order to assume a first turret position, wherein it is fixable to the heel of a ski boot, so that it is possible to ski downhill, and in order to assume a second turret position, wherein it is not fixable to the heel of a ski boot, so that it is possible to walk uphill;
• a brake for a ski;
• wherein:
• the brake comprises a braking lever which is rotatable to assume a braking position, in which it can brake a ski when the base is fixed to the ski, and a non-active position, in which it is non-active;
• the brake comprises first elastic means for rotating the braking lever towards the braking position;
• the braking lever is arranged so as to be pressable by the heel of the ski boot, when the base is fixed to the ski and the turret is in the first turret position, in order to reach the non-active position against the action of the first elastic means;
• further comprising:
• a rotation member which is rotatingly borne by the base and which in turn bears the braking lever so that a rotation of the rotation member corresponds to a rotation of the braking lever, and vice versa;
• and
• connecting means which connect the rotation member and the turret to one another, in such a way that the rotation member and the turret are solidly constrained to one another, when the turret is in the second turret position and when the braking lever is in the non-active position, so that it is possible to walk uphill, wherein:
• the rotation member is provided with a first arched cogging;
• the turret comprises a cam;
• the connecting means comprise a connecting element which is movable by translation, and which comprises a second straight cogging and a cam follower;
• the connecting element is coupled to the rotation member by enmeshing of the relative second straight cogging with the first arched cogging so that a translating movement of the connecting element determines a rotation of the rotation member, and vice versa;
• and
• the cam of the turret engages with the cam follower of the connecting element when the turret is rotated from the first turret position to the second turret position, so that the connecting element generates a first rotation torque on the rotation member which brings the braking lever into the non-active position, against the action of the first elastic means.

• the turret bears a first abutment;
• the connecting means comprise a connecting element which is movable by translation, and which comprises a second straight cogging and a second abutment element;
• the connecting element is coupled to the rotation member by enmeshing of the relative second straight cogging with the first arched cogging so that a translating movement of the connecting element determines a rotation of the rotation member, and vice versa;
• and
• when the braking lever is in the non-active position the turret can reach the second turret position, so that the first abutment abuts the second abutting element preventing the braking lever from being brought into the braking position due to the action of the first elastic means.
