Ski with a connecting device for a ski binding

1. A ski with a connecting device for connecting a ski binding comprising a front and rear cup piece to the ski, comprising a plate-type support body for the front and rear cup pieces, which support body is designed at its front end portion to retain the front cup piece and at its rear end portion to retain the rear cup piece, and the support body has a fixing zone in its longitudinal middle portion for rigidly connecting to the ski, and at least the front end portion of the support body constitutes a flexural element extending freely with respect to the fixing zone and to the ski, the lengthways end of which facing away from the fixing zone is connected to the ski by means of at least one mechanical coupling device so as to be relatively displaceable, wherein the freely extending flexural element is made from plastic, and the coupling device comprises a connecting arm which has a first articulated connection to the flexural element in its first end portion and a second articulated connection to the ski in its second end portion, and the first or second articulated connection is disposed on a guide carriage displaceable in a sliding movement in the ski longitudinal direction, and a restrictor element is provided for suppressing, restricting or inhibiting lifting movements of the flexural element relative to the ski.

2. The ski according to claim 1 , wherein at least the freely extending flexural element of the support body is made from injection molded plastic reinforced with glass fiber.

3. The ski according to claim 1 , wherein the coupling device comprises an essentially C-shaped bearing body by reference to a vertical longitudinal section extending parallel with the ski longitudinal direction, the bottom arm of which has a bearing point for the connecting arm and the top arm of which forms the restrictor element.

4. The ski according to claim 1 , wherein the guide carriage comprises a slide plate which is guided in a sliding movement in a guide groove on the flexural element in the ski longitudinal direction and which is coupled with the connecting arm via the first articulated connection.

5. The ski according to claim 1 , wherein the flexural element is supported by means of a support body which is elastically flexible relative to the ski, disposed between the top face of the ski and the bottom face of the flexural element.

6. The ski according to claim 5 , wherein the elastically flexible support body has a seating length by reference to the ski longitudinal direction of less than 5 cm with respect to the top face of the ski and/or a supporting length by reference to the ski longitudinal direction of less than 5 cm with respect to the flexural element.

7. The ski according to claim 1 , wherein the rear end portion of the support body is supported on the ski top face in a load-transmitting arrangement by means of a fixing device, being retained so as to slide freely in the ski longitudinal direction and secured to prevent any lifting from the ski top face.

8. The ski according to claim 7 , wherein the fixing device comprises a clamp-type or clip-type fixing element which extends round or extends through the support body in its rear end portion and is rigidly screwed to the ski.

9. The ski according to claim 1 , wherein the front and/or the rear end portion of the support body has an essentially top-hat rail or C-shaped cross-sectional contour, which forms a longitudinal guide for the front and/or rear cup piece.

10. The ski according to claim 1 , wherein the support body has a lesser stiffness with respect to flexing than the ski within its longitudinal portion overlapping the support body.
