Abstract: A heel holder arrangement of a safety ski binding has a sole holder which is pivotable about a first axis parallel to the surface of the ski between a position of locking the heel of a ski boot and a release position. Arranged behind the sole holder and pivotable about a second parallel axis is a retaining lever which at its upward end carries at least one retaining roller. The retaining roller co-operates both with a cam surface on the sole holder and also with a cam surface on a pivotable opening lever which is loaded by a compression spring. The cam surface on the sole holder includes a retaining recess in which the retaining roller is engaged when the sole holder is in the locking position. The spring is pivotable with the opening lever. The cam surfaces jointly determine the force-travel characteristic of the sole holder both in the event of safety release of the arrangement and also upon voluntary opening by actuation of the opening lever.

Abstract: A front jaw having two laterally spaced toggle levers which can be swung out against the force of a release spring housed in a housing and through which housing extends a pull rod. In order to cause in this front jaw during a backward twisting fall an initial tension of the release spring and thus a reduction in the work of the swinging-out toggle lever, the invention provides that the two shorter lever arms of the toggle levers are loaded by a release spring acting through a pull rod onto an angular intermediate lever supported in the lower area of the housing on a first pivot axle.

Abstract: A sideways releasable jaw of a ski binding for holding one end of the ski boot (9) has a binding housing (11) in which a release spring (14) is arranged The release spring (14) extends substantially in the longitudinal direction of the ski and is braced at one end against the binding housing (11). At its other end it exerts a release force with a substantial component in the longitudinal direction of the ski pointing away from the ski boot (9) on a sole clamp (22) arranged towards the ski boot (9). On exceeding a predetermined sideways force exerted by the ski boot (9) the sole clamp (22) can pivot sideways about a substantially upright pivotal axis and releases the ski boot (9). In so doing the release spring exerts a downwardly directed force component on the sole clamp which is vertically displaceably arranged on the binding housing (11) for movement along an upright sliding guide. Thus the sole clamp (22) is pressed against the upper side of the sole (29) of the ski boot.

Abstract: Described is a safety ski binding with a sole plate which can pivot about a pivot pin parallel to the surface of the ski and is connected to the ski. The sole plate is fixed in a central position, so that it cannot pivot laterally relative to the ski, by means of a spring-biased fixture fitted at the rear end of the sole plate, but the sole plate pivots out laterally relative to the ski against the spring bias when a given moment is exceeded. In order to avoid loading the pivot pin in the sole plate, and in the ski itself, by the force exerted by the spring, the invention calls for the fixture to have swivelling levers which, in their locking position, in which they hold the sole plate in its central position, rest against a stop disposed at right angles to the ski next to the swivelling levers.

Abstract: A ski binding component, such as a front jaw, arranged movably in longitudinal direction of a ski on a ski-fixed guide rail and being releasably lockable in predetermined positions. To fix each chosen position of the ski binding component on the guide rail, a locking part with an operating member is provided and which is adjustable to two different elevational positions, which locking part is biassed by a spring. In order to be able to use such a ski binding component together with a heel holder connected by means of a metal band to the ski binding component, the invention provides that the operating member has three surfaces through which the locking part provides two defined locking positions. Thus, it is possible to adjust either the heel holder and the connected metal band relative to the front jaw or both the front jaw and the heel holder can be adjusted in longitudinal direction of the ski.

Abstract: The invention relates to a ski binding (1) with a toe-holding unit (2) and a heel-holding unit (3). Release mechanisms (8) are integrated in the latter and can be set to different releasing forces. Detachably fastened on the ski are longitudinal guidance devices (5, 6) for the toe-holding and/or heel-holding unit (2, 3), which are movably connected to the connecting element (4). The toe-holding and/or heel-holding unit (2, 3) can be fixed by an arresting device (17) for fixing the toe-holding unit (2) in a longitudinal guidance device (5) and/or a transverse guidance device (74).

Abstract: A releasable ski binding is provided with a boot holder which can be swivelled around a vertical shaft and is pushed into a normal ski boot holding position by a piston. At its end facing the boot holder, the piston is arranged to be slidable into the transverse direction with play, and at its other end, the piston is arranged to be slidable in a guide almost without play. Thus, swivel motions of the boot holder can take place largely without friction between the boot holder and the piston parts which rest against it. At the same time, the normal position is defined virtually without play.

Abstract: In a safety ski binding with a heel unit which includes a bearing housing (11), a sole holder (13), a hand opening lever (15) and a release spring (16), an actuating abutment (22) is arranged on the sole holder (13) at a distance (A) from the first transverse axle (12) which is substantially smaller than the distance (B) of the culmination point from the first transverse axle (12). Moreover, a counter-abutment (23) which cooperates with the actuating abutment (22) is provided on the hand opening lever (15), with one of the two abutments (22, 23) being made resiliently yielding. Through cooperation of the two abutments (22, 23) the sole holder (13) pivots at a higher speed than the hand opening lever (15) into its open position. As a result the horizontal sliding section (32) enters into engagement again with the latch projection (17) shortly before reaching the culmination point (21), so that the further pivoting is only possible under compression of the resilient abutment.

Abstract: A ski boot, and a binding for binding the ski boot onto the ski. The boot is provided with blocking means which prevents its attachment by bindings other than those which should properly be used with the specific boots. The binding itself however is capable of use with any standardized boot, whether or not it has blocking means. This assures that boots requiring specially modified bindings will not be used otherwise, but nevertheless permits the use of such boots with bindings used with standardized boots having no blocking means.
