This invention concerns a basic arrangement of a ski binding having a front part or a toe end and a rear part or a heel end for securing the ski boot, and also having a front supporting part, longitudinally displaceable on a first base part fixed on the ski, for supporting the front boot holding part, and a rear supporting part, longitudinally displaceable on another base part fixed on the ski, for supporting the rear boot holding part. The invention further includes an adjusting device designed as a rack-and-pinion gear for simultaneous adjustment of both supporting parts; this adjusting device has two toothed racks, each connected to a supporting part, and a manually operable, lockable gearwheel which meshes with both toothed racks between the two supporting parts. In one embodiment, the gearwheel is arranged on a middle base part in an essentially stationary mount on the ski, and is separate from the front and rear base parts, and is held indirectly on the ski by the front and rear base parts. In another embodiment, the gearwheel has an unlocked position which is raised vertically relative to the top side of the ski for the rotational adjustment, and a locked position which is depressed toward the top side of the ski.

A basic arrangement according to claim 1, wherein the gearwheel adjoins a plastic hand wheel and a second gearwheel which has the same contour as the gearwheel and when said gearwheel is in the locked position, said second gearwheel works together with the toothed racks and when said gearwheel is in the unlocked position, said gearwheel works together with the toothed racks. 4. A basic arrangement according to claim 2, wherein the gearwheel and the second gearwheel have a lower position or a catch position secured by the spring system and are lifted by a lifting device against the force of the spring system. 5. A basic arrangement according to claim 1, wherein a lever lifts the gearwheel out of the locked position and adjust into the locked position, with the lever projecting over a longitudinal edge of the ski when the gearwheel is unlocked. 6. A basic arrangement according to claim 5, wherein a spring arrangement under tension puts the lever into the position locking the gearwheel, and the position of the lever unlocking the gearwheel is top dead center. 7. A basic arrangement according to claim 3, wherein said gearwheel is metal. 8. A basic arrangement according to claim 3, wherein said second gearwheel is plastic. 9. A basic arrangement of a ski binding having;a front boot holding part or a toe end for securing a ski boot;a first base part fixed on the ski;a front supporting part longitudinally displaceable on the first base part, said front supporting part supporting the front boot holding part;a rear boot holdings part or a heel end for securing the ski boot;a second base part fixed on the ski;a rear supporting part longitudinally displaceable on the second base part, said rear supporting part supporting the rear boot holding part;a rack-and-pinion gear adjusting device for simultaneous adjustment of both said front supporting part and said rear supporting part, said device having two toothed racks, the first rack connected to the front supporting part and the second rack connected to the rear supporting part, and a manually operable, lockable gearwheel which meshes with both toothed racks between the two supporting parts;a third base part in an essentially stationary mount on the ski, said third base part being separate from the first and second base parts and said third base part being held indirectly on the ski by the first and second base parts to restrict movement of said third base part,wherein the gearwheel is arranged on the third base part, and the gearwheel has a locked position in a fixed position on the ski, and the toothed racks are arranged pivotally about a transverse axis of the ski in the meshing zone of the gearwheel,wherein the gearwheel is fixedly arranged or integrally molded on a hand wheel, and the hand wheel and the gearwheel have a vertically raised position with respect to the top side of the ski for the rotational adjustment, a locked position depressed toward the top side of the ski, and a meshing position wherein at least one of the gearwheel or a gearing provided on the hand wheel meshes with a stationary lock gearing and works together with the lock gearing.
