Ski binding

A toe-piece to be mounted to a gliding board for binding a boot onto the gliding board, the toe-piece comprising:

• a frame being fixed against movement in relation to the gliding board in use when the frame is mounted on the gliding board;
• two wings each pivotably mounted in relation to the frame about a respective axis of rotation and supporting a respective lateral interface surface which contacts a front portion of the boot when the toe-piece is in a descent configuration;
• a lateral release mechanism comprising:
• a displaceable connecting element connected to the wings such that displacement of the connecting element causes rotation of the wings about the axes of rotation;
• a first elastic member having a first end and a second end, the first end being connected to the displaceable connecting member;
• a body against which the second end of the first elastic member elastically presses;
• the body being movable in relation to the frame;
• an adjustment mechanism acting on the wings to selectively position the wings, in relation to the boot during a single fixed position of the boot in relation to the toe-piece, in either of the following two alternate configurations:
• a first configuration, in which each of the respective lateral interface surfaces is in contact with the boot;
• and
• a second configuration, in which each of the respective lateral interface surfaces is away from the boot.
