A ski or a snowboard is in the form of a board-type gliding device. By reference to the width of the gliding device, at least one recess is provided in its middle portion extending in its depth direction from the top face of the gliding device in the direction towards the running surface facing and disposed in its longitudinal direction essentially parallel with the longitudinal direction of the gliding device with a view to causing a cross-sectional weakening. At least one manually adjustable adjusting device is provided, which is designed to produce an individually adjustable change in the load-dependent deformability of the cross-sectional shape or to produce an individually adjustable limit to the maximum permissible load-dependent cross-sectional deformation of the gliding device. Further, a ski or a snowboard is provided with a manually adjustable adjusting device which is designed to act as a spreading device for producing an individually adjustable increase in the width of the recess on the one hand and to act as a pulling device to produce an individually adjustable decrease in the width of the recess on the other hand.

1. Ski or snowboard in the form of a board-type gliding device, comprising at least one top belt for imparting strength, at least one bottom belt for imparting strength and at least one core disposed in between, a top layer constituting the top face of the gliding device and a running surface constituting the bottom face of the gliding device, and, by reference to the width of the gliding device, at least one recess is provided in its middle portion extending in its depth direction from the top face of the gliding device in the direction towards the running surface and disposed in its longitudinal direction essentially parallel with the longitudinal direction of the gliding device with a view to causing a cross sectional weakening and reducing the stiffness of the gliding device transversely to its longitudinal direction, being provided with means for producing a cross-sectional shape or contour of the gliding device which is variable depending on load and/or manually variable, wherein at least one manually adjustable adjusting means is provided, which is designed on the one hand to act as a spreading means for producing an individually pre-adjustable increase in the width of the recess and on the other hand to act as a pulling means for producing an individually pre-adjustable reduction in the width of the recess, and the adjusting means selectively acts as an active spreading means or an active pulling means between the portions of the gliding device lying to the left and right of the recess depending on its individually selectable setting and wherein the at least one manually adjustable adjusting means, which is made of one piece and is moveable along the longitudinal axis of the gliding device, has at least two support or guide surfaces extending obliquely with respect to the longitudinal axis and perpendicular with respect to the running surface of the gliding device, which support surfaces cooperate with thrust surfaces on the top face of the gliding device or with longitudinal side walls of the groove-type recess so that when the adjusting means is shifted along the longitudinal axis, the support surfaces slide along the thrust surfaces or the longitudinal side walls and the recess is spread and pulled, respectively. 2. Ski or snowboard according to claim 1, wherein the recess divides or splits the strength imparting top belt essentially within its longitudinal extension into a first or left-hand and a second or right-hand top belt strand. 3. Ski or snowboard according to claim 1, wherein the recess extends from the top face in the depth direction as far as the bottom belt or weakens or reduces the cross-section of the bottom belt, and the running surface extends at least within the longitudinal extension of the recess starting from the left-hand side edge of the gliding device continuously as far as the right-hand side edge of the gliding device. 4. Ski or snowboard according to claim 1, wherein the recess extends across 50% to 90%, preferably across approximately 75%, of the biggest cross-sectional height of the gliding device within this cross-sectional plane. 5. Ski or snowboard according to claim 1, wherein the recess or several recesses aligned in a row in the longitudinal direction of the gliding device extends or extend across 40% to 80%, preferably across approximately 60%, of the length of the gliding device. 6. Ski or snowboard according to claim 1, wherein the recess extends across 50% to 90%, preferably across approximately 75%, of the front longitudinal portion between a binding mechanism and the front end of the gliding device. 7. Ski or snowboard according to claim 1, wherein the recess, which runs continuously or discontinuously, extends as far as the front, upwardly curved shovel portion and extends through at least part-portions of the upwardly extending curvature of the front shovel portion and reduces the transverse stiffness of the front shovel portion. 8. Ski or snowboard according to claim 1, wherein a depth of the recess decreases, starting from a mounting portion for a binding mechanism in the direction towards the rear end and/or in the direction towards the front shovel portion of the gliding device. 9. Ski or snowboard according to claim 1, wherein a base of the recess is of a crease-type shape or is of a rounded design. 10. Ski or snowboard according to claim 1, wherein the adjusting means is designed to vary a width of the recess on an individually pre-settable basis and selectively to permit and to prevent and/or limit a load-dependent variability of the width of the recess. 11. Ski or snowboard according to claim 1, wherein the thrust surfaces are provided in the form of projections fixedly joined to the board-type gliding device. 12. Ski or snowboard according to claim 1, wherein the adjusting means can be switched between an inactive position and at least one active position and vice versa, and when the adjusting means is in an active position, support surfaces are activated in order to provide support between the left-hand and right-hand portions of the gliding device and prevent a load-dependent reduction in the width of the recess or to afford an elastic resistance to a load-dependent reducing movement in the width of the recess. 13. Ski or snowboard according to claim 1, wherein the adjusting means has a lever or gear arrangement for transferring the adjusting means from the inactive position into at least one active position with additional force. 14. Ski or snowboard according to claim 13, wherein the lever or gear arrangement is designed to be operated without tools. 15. Ski or snowboard according to claim 1, wherein the top layer is provided in the form of a plastic layer and lines the longitudinal side walls and base of the recess. 16. Ski or snowboard according to claim 1, wherein the top layer is provided as a one-piece plastic layer which extends from the top face down to the base of the recess and back up to the top face of the gliding device.
