Ski binding comprising a toe piece and a heel piece slideably mounted on a slide (1) and respectively supporting two connecting arms (2, 3) providing a rack (19, 20) engaging respectively two gears (6, 7); an auxiliary gear means (8, 9) and a gear (7) displaceable, for example, vertically in a manne

Ski binding comprising a toe piece and a heel piece slideably mounted on a slide (1) and respectively supporting two connecting arms (2, 3) providing a rack (19, 20) engaging respectively two gears (6, 7); an auxiliary gear means (8, 9) and a gear (7) displaceable, for example, vertically in a manner to be able to occupy two different levels in which it engages with two different gears, the binding elements being displaceable either symmetrically in opposite directions in a manner to enable the adjustment of the binding to the length of the boot without changing the central position of the boot relative to the ski, or in the same direction in a manner to be able to change the central position of the boot relative to the ski.

[ What is claimed is:] [1.] A binding device for attaching a ski boot to a ski comprising a front binding element (4) and a rear binding element (5) longitudinally displaceable on a slide (1) fixed to the ski and respectively interconnected with connecting bars (2, 3), these connecting bars being provided with arms (17, 18) which extend parallel to the longitudinal axis of the slide on each side of the axis, each arm facing each other and presenting a toothed rack (19, 20) facing the teeth of the opposed arms for their mutual driving by a gear coupling device mounted between the arms and on a perpendicular axis to the ski and rotatably lockable by manually actuatable locking and unlocking means (11), unlocking permitting the simultaneous longitudinal displacement of binding elements by the displacement of the one of the binding elements, characterized in that the gear coupling device comprises a first principal gear (6) engaged with the teeth (20) of the arms, a second principal gear (7) of the same diameter and the same module as the first gear, engaged with the teeth (19) of the other arm, and at least two auxiliary gears (8, 9), one (7) of the four gears able to occupy a first and a second position, which when the gear occupies the first position, the first principal gear (6) and the second principal gear (7) engage directly one with the other or by an intermediary of at least one auxiliary gear such that they turn in opposite directions and, when the gear occupies the second position, the first principal gear (6) and the second principal gear (7) are coupled by an intermediary of at least one auxiliary gear (8,9) such that they turn in the same direction.
